  • [Title] Gene expression analysis of angioimmunoblastic lymphoma indicates derivation from T follicular helper cells and vascular endothelial growth factor deregulation.
  • Angioimmunoblastic lymphoma (AILT) is the second most common subtype of peripheral T-cell lymphoma (PTCL) and is characterized by dismal prognosis.
  • We performed gene expression profile (GEP) analysis of six AILT, six anaplastic large cell lymphomas (ALCL), 28 PTCL-unspecified (PTCL/U), and 20 samples of normal T lymphocytes (including CD4(+), CD8(+), and activated and resting subpopulations), aiming to (a) assess the relationship of AILT with other PTCLs, (b) establish the relationship between AILT and normal T-cell subsets, and (c) recognize the cellular programs deregulated in AILT possibly looking for novel potential therapeutic targets.
  • First, we found that AILT and other PTCLs have rather similar GEP, possibly sharing common oncogenic pathways.
  • Furthermore, we found that the molecular signature of follicular T helper cells was significantly overexpressed in AILT, reinforcing the idea that AILT may arise from such cellular counterpart.
  • Finally, we identified several genes deregulated in AILT, including PDGFRA, REL, and VEGF.
  • The expression of several molecules was then studied by immunohistochemistry on tissue microarrays containing 45 independent AILT cases.
  • Notably, we found that the vascular endothelial growth factor (VEGF) was expressed not only by reactive cells, but also by neoplastic cells, and that nuclear factor-kappaB (NF-kappaB) activation is uncommon in AILT, as suggested by frequent exclusively cytoplasmic c-REL localization.
  • Our study provides new relevant information on AILT biology and new candidates for possible therapeutic targets such as PDGFRA (platelet-derived growth factor alpha) and VEGF.

  • [Title] Angioimmunoblastic T-cell lymphoma developed with lymphocytic pleural effusion.
  • Angioimmunoblastic T-cell lymphoma (AILT) is a rare variant of nodal and aggressive lymphoma.
  • It is sometimes difficult to distinguish AILT from reactive lymphoid hyperplasia from the histopathological aspect.
  • We report a case of AILT which developed with bilateral pleural effusion.
  • Although we could not further identify the tumor cells in this case, analysis of pleural effusion cells will increase our understanding of the pathogenesis and the pathophysiology of AILT.

  • [Title] The frequency of B- and T-cell gene rearrangements and epstein-barr virus in T-cell lymphomas: a comparison between angioimmunoblastic T-cell lymphoma and peripheral T-cell lymphoma, unspecified with and without associated B-cell proliferations.
  • We report on a series of 58 cases of angioimmunoblastic T-cell lymphoma (AILT) and 59 cases of peripheral T-cell lymphoma, unspecified (PTCL-NOS).
  • Subsets of cases from both diagnostic groups were complicated by associated B-cell proliferations, and we performed B- and T-cell clonality studies and in situ hybridization for Epstein-Barr virus (EBV) to investigate the relationship between B-cell proliferation, B-cell clonality, and EBV.
  • Using multiplex polymerase chain reaction assays based on the BIOMED-2 collaborative study, we detected TCRgamma T-cell clones in 78 and 81% of AILT and PTCL-NOS cases, respectively, and IGH B-cell clones in 34 and 35% of AILT and PTCL-NOS cases, respectively.
  • The majority of cases contained EBV-positive cells, including 50% of AILT and 57% of PTCL-NOS cases, and cases with B-cell proliferations were more often EBV-positive.
  • Although a relatively high rate of B-cell clonality has been shown for AILT, our findings for PTCL-NOS differ from previous reports in that B-cell clonality was relatively frequent.
  • Overall, a positive B-cell clone correlated, in part, with the presence of a B-cell proliferation but not with EBV.
  • Our findings demonstrate that B-cell clonality is a common finding in AILT and PTCL-NOS, and its presence should not negate the diagnosis established by morphologic, immunophenotypic, and clinical findings.

  • [Title] Analysis of single nucleotide polymorphisms in the FAS and CTLA-4 genes of peripheral T-cell lymphomas.
  • Angioimmunoblastic T-cell lymphoma (AILT) represents a subset of T-cell lymphomas but resembles an autoimmune disease in many of its clinical aspects.
  • We investigated single nucleotide polymorphisms (SNPs) of the FAS and CTLA-4 genes in 94 peripheral T-cell lymphomas.
  • Although allelic frequencies of some FAS SNPs were enriched in AILT cases, none of these occurred at a different frequency compared to healthy individuals.
  • Therefore, SNPs in these genes are not associated with the apoptotic defect and autoimmune phenomena in AILT.

  • [Title] Epstein-Barr virus genome level, T-cell clonality and the prognosis of angioimmunoblastic T-cell lymphoma.
  • BACKGROUND AND OBJECTIVES: Angioimmunoblastic T-cell lymphoma (AILT) is a peripheral T-cell tumor of unknown etiology with variable biological and clinical presentations.
  • Previous clonality studies have shown heterogeneous clonal restrictions of B- and T-cell populations in this tumor.
  • AILT is characterized by the presence of increased numbers of Epstein-Barr virus (EBV) infected cells.
  • DESIGN AND METHODS: Frozen material from 59 cases of AILT was used for DNA isolation and gene analysis by Southern blotting.
  • Survival rate did not correlate with either T-cell clonality (p=0.84), or presence of EBV-infected cells (p=0.84).
  • The EBV-DNA copy number in EBV-infected tissue did not correlate with disease progression (p=0.87).
  • The survival rate and clinical status according to the international prognostic index (IPI) did not correlate with T-cell clonality status or EBV infection.
  • INTERPRETATION AND CONCLUSIONS: AILT remains a heterogeneous disease with clinical behavior that varies irrespective of the genomic parameters investigated.

  • [Title] Characterization of angioimmunoblastic T-cell lymphomas (AILT) and its association with Epstein-Barr virus (EBV) in Pakistani patients.
  • OBJECTIVE: To characterize angioimmunoblastic T-cell lymphoma (AILT) on morphological, immunohistochemical and molecular grounds and its association with Epstein-Barr virus (EBV) in Pakistani patients.
  • PATIENTS AND METHODS: Over a period of 11 years archival biopsy material of 13 AILT cases (lymph nodes), identified on the basis of histological and immunohistochemical criteria, using REAL and WHO classifications, were retrieved from the files of Department of Pathology.
  • Immunophenotyping was carried out by using CD45 (LCA), two T-cell markers CD45RO (UCHL1; monoclonal) and CD3 (polyclonal).
  • Polymerase chain reaction (PCR) was used to assess T-cell clonality for T-cell receptor (TCR)-b, g and immunoglobulin heavy chain (IgH) for FR2 and FR3 regions using primers recognizing conserved sequences of the variable (V), diversity (D) and joining (J) region segments.
  • Association of EBV in AILT cases was studied by PCR and in situ hybridization (ISH).
  • RESULTS: This study showed AILT to constitute 0.71% of all NHLs (non-Hodgkin's lymphoma) [both T and B].
  • All the 13 cases were largely negative for CD20 (L26), a B-cell marker, except few large scattered cells labelling.
  • PCR technique demonstrated clonal gene rearrangement of the TCR-b, g and IgH regions in 3 (23.1%), 7 (53.8%) and 3 (23.1%) AILT cases, respectively out of 13 cases.
  • Association of EBV was seen in 11 out of 13 cases (84.6%) of AILT by PCR.
  • CONCLUSION: The prevalence of AILT in the Pakistani population is slightly lower compared to other studies and that EBV is an etiological agent in pathogenesis of this disease.

  • [Title] Frequent occurrence of B-cell lymphomas in angioimmunoblastic T-cell lymphoma and proliferation of Epstein-Barr virus-infected cells in early cases.
  • Secondary lymphomas occurring in the setting of angioimmunoblastic T-cell lymphoma (AILT) are considered to be rare.
  • A previous study detected a dysregulated hypermutation process in B-cells of AILT.
  • The present study aimed at estimating the frequency of B-cell lymphomas in AILT.
  • By studying the expression of EBV and activation-induced cytidine deaminase (AID) as an indicator of hypermutating cells, we assessed whether B-cell lymphoproliferations in AILT were strictly associated with EBV and whether hypermutation might contribute to lymphomagenesis.
  • Among 161 cases of AILT, diagnosed between 1996 and 2005 at the lymph node registry, Frankfurt, Germany, 19 cases were detected that also had B-cell non-Hodgkin lymphoma (NHL) and two cases had classical Hodgkin lymphoma (HL).
  • AID was expressed in AILT in large cells disseminated in the tissue, implying that the process of somatic hypermutation is ongoing in AILT, although the GC architecture is disrupted.
  • This might be relevant in the development of secondary lymphomas.

  • [Title] Chromosomal aberrations in angioimmunoblastic T-cell lymphoma and peripheral T-cell lymphoma unspecified: A matrix-based CGH approach.
  • Angioimmunoblastic T-cell lymphoma (AILT) is a histopathologically well-defined entity.
  • However, despite a number of cytogenetic studies, the genetic basis of this lymphoma entity is not clear.
  • Moreover, there is an overlap to some cases of peripheral T-cell lymphoma unspecified (PTCL-u) in respect to morphological and genetic features.
  • We used array-based comparative genomic hybridization (CGH) to study genetic imbalances in 39 AILT and 20 PTCL-u.
  • Array-based CGH revealed complex genetic imbalances in both AILT and PTCL-u.
  • Chromosomal imbalances were more frequent in PTCL-u than in AILT and gains exceeded the losses.
  • The most recurrent changes in AILT were gains of 22q, 19, and 11p11-q14 (11q13) and losses of 13q.
  • Interestingly, gains of 4q (4q28-q31 and 4q34-qtel), 8q24, and 17 were significantly more frequent in PTCL-u than in AILT.
  • Moreover, we could identify a recurrent gain of 11q13 in both AILT and PTCL-u, which has previously not been described in AILT.
  • Trisomies 3 and 5, which have been described as typical aberrations in AILT, were identified only in a small number of cases.
  • In conclusion, CGH revealed common genetic events in peripheral T-cell lymphomas as well as peculiar differences between AILT and PTCL-u.

  • [Title] Angiogenic mediators of the angiopoietin system are highly expressed by CD10-positive lymphoma cells in angioimmunoblastic T-cell lymphoma.
  • Angioimmunoblastic T-cell lymphoma (AILT) is a malignant disease of peripheral T-cell origin that is characterized by a prominent proliferation of high endothelial venules in the lymph node.
  • To investigate angiogenic mechanisms in AILT we measured the angiogenic mediator gene expression levels in the lymph nodes of 54 non-Hodgkin lymphoma patients, by immunostaining and quantitative reverse transcription polymerase chain reaction.
  • Angiogenic mediators angiopoietin (Ang) 1 (ANGPT1), Ang2 (ANGPT2) and their receptor, Tie2 (TEK), vascular endothelial growth factor (VEGF; VEGFA) and its receptor, VEGFR2 (KDR), and hepatocyte growth factor (HGF) and its receptor, c-Met (MET) were all more highly expressed in AILT lymph nodes (16 cases) than in B-cell lymphomas (24 cases).
  • Moreover, significantly higher Ang1 and Tie2 expression was detected in AILT cases with CD10-positive neoplastic T-cells by comparison with unspecified peripheral T-cell lymphoma (14 cases).
  • These results suggest that the angiopoietin system may play an important role in the development of high vascularity in AILT lymph nodes.
  • Consequently, as neoplastic T-cells and follicular dendritic cells are both increased in AILT and may represent an important source of angiogenic mediators, targeting these cells with anti-angiogenic strategies might represent a novel therapy for AILT.

  • [Title] c-Maf expression in angioimmunoblastic T-cell lymphoma.
  • We previously examined c-Maf expression in various T-cell lymphomas by reverse-transcription polymerase chain reaction and found extremely elevated c-Maf levels in angioimmunoblastic T-cell lymphoma (AILT).
  • In this study, we examined T-cell lymphomas for c-Maf and cyclin expression immunohistochemically.
  • Of 93 cases of T-cell lymphomas we investigated in the current study, c-Maf expression was seen in 23 out of 31 cases of AILT, 3 out of 11 of adult T-cell leukemia/lymphoma, 4 out of 19 of peripheral T-cell lymphoma, unspecified [PTCL(U)], and 0 out of 11 cases of mycosis fungoides, 0 out of 11 of anaplastic large cell lymphoma, and 1 out of 10 of extranodal NK/T-cell lymphoma, nasal type.
  • Double immunostaining in AILT revealed that the majority of c-Maf-positive cells were also positive for CD43 (MT1), CD45RO (UCHL-1), and CD4 but were negative for CD20 (L26).
  • Additionally, cyclins D1 and D2, which stimulate cell cycle progression, were overexpressed in a large number of the c-Maf-positive AILT samples.
  • Quantitative reverse-transcription polymerase chain reaction analysis also showed that c-Maf was overexpressed in 8/31 cases of AILT, 0/19 cases of PTCL(U), 0/11 cases of anaplastic large cell lymphoma, 0/10 cases of extranodal NK/T-cell lymphoma, nasal type, and 2/8 cases of multiple myeloma, presenting significant difference between AILT and PTCL(U) (P=0.016, chi test).
  • These findings strongly suggest that CD4-positive neoplastic T cells in AILT show c-Maf expression and provide new insight into the pathogenesis of AILT suggesting c-Maf to be a useful diagnostic marker for AILT.

  • : e19538 Background: Peripheral T-cell lymphoma is a rare entitydisease, compromising 10% of non-Hodgkin's lymphoma worldwide and 5% of all lymphoid neoplasms in the United States.
  • High-dose chemotherapy followed by autologous haematopoietic stem cell transplantation, has been explored in recent years with little experiences.
  • METHODS: A retrospective analysis on patients with diagnosis of peripheral T-cell lymphoma receiving autologous stem cell transplant was conducted (January 1997 to July 2008).
  • The patients were stratified according to their International Prognostic Index (IPI), disease status at the time of transplant and histology type.
  • RESULTS: Twenty-nine subjects were identified, with a median age of 51; 13 patients had Anaplastic T cell, 18 patient had PTCL-nos, and 6 patients with angioimmunoblastic T cell lymphoma.
  • Seventeen patients (58.62%) presented with an aa IPI score greater than 2.4 patients were in complete remission, 15 at first relapse, 4 in greater than 1 episode, and 6 with refractory disease at the time of transplantion.Kaplan Meier overall survival (OS) 72 and relapse free survival (RFS) was 62 at 1 year respectively.
  • A multivariate analysis and new risk stratification based on the IPI score system and disease status at time of transplant were employed.
  • CONCLUSIONS: The status at time of transplant with new methods for evaluation of minimal residual disease may help in assessing outcome.

  • A 30-year-old Japanese female with an 18-year history of SLE presented with right neck lymphadenopathy of 3 months duration.
  • Interestingly, the immunohistochemical study demonstrated large, irregularly shaped accumulations of follicular dendritic cells (FDCs) surrounding the small vessels, which is an immunohistochemical finding characteristic of angioimmunoblastic T-cell lymphoma (AILT).
  • However, the present lesion showed the following differences to AILT: (a) absence of CD3+, CD4+ and CD10+ clear cells, which are tumor cells of AILT;.
  • (c) on molecular analysis, the present case demonstrated a polyclonal pattern converse to the monoclonal T-cell receptor gamma chain gene rearrangement in most AILTs (d) absence of EBV infected lymphoid cells, which are frequently detected AILT.
  • As previously suggested, the present case indicates that a clinical correlation as well as immunohistologic and genotypic studies may be necessary to discriminate between ALPIBPs and AILT.

  • Angioimmunoblastic T-cell lymphoma (AILT) and peripheral T-cell lymphoma, unspecified (PTCL-u) are relatively frequent subtypes of T- or natural killer cell lymphoma.
  • To characterize the structural anomalies of chromosomes associated with these disorders, we here determined chromosome copy number alterations (CNAs) and loss of heterozygosity (LOH) at >55,000 single nucleotide polymorphism loci for clinical specimens of AILT (n=40) or PTCL-u (n=33).
  • AILT- or PTCL-u-specific CNAs or LOH were also identified at 21 regions, some spanning only a few hundred base pairs.
  • Our data indicate that AILT and PTCL-u consist of heterogeneous subgroups with distinct transforming genetic alterations.

  • [Title] Adult T-cell lymphoma/leukemia with angioimmunoblastic T-cell lymphomalike features: Report of 11 cases.
  • In adult T-cell lymphoma/leukemia (ATLL), the neoplastic lymphoid cells are usually medium-sized to large, often with pronounced nuclear pleomorphism compatible with the diagnosis of diffuse pleomorphic peripheral T-cell lymphoma.
  • We describe here 11 patients with the rare morphologic variant of ATLL, angioimmunoblastic T-cell lymphoma (AILT)-like type.
  • The lymphoma cells were medium-to-large size with clear cytoplasm.
  • These findings were suggestive of AILT.
  • However, immunohistochemical features of AILT, namely, CD10 and CXCL13 expression in lymphoma cells and proliferation of CD21-positive follicular dendritic cells, were not detected.
  • All patients were positive for antiadult T-cell leukemia/lymphoma-associated antigen, which is a specific antibody for human T-cell lymphotropic virus type-I.
  • Southern blot analysis revealed proviral DNA integration in lymphoma cells in 9 patients.
  • This is the first report of ATLL with AILT-like morphologic features.

  • [Title] Nodal peripheral T-cell lymphomas correspond to distinct mature T-cell populations.
  • Peripheral T-cell lymphomas (PTCL) have not been successfully correlated with specific developmental stages of reactive T-cells.
  • In this study, we evaluated lymph node biopsies from eight PTCL-not otherwise specified (PTCL-NOS), seven angioimmunoblastic T-cell lymphomas (AILT), and 15 anaplastic large cell lymphomas (ALCL).
  • Detection of tumour cells with antibodies that recognize specific rearranged T-cell receptor Vbeta segments allowed us to investigate the expression of various differentiation-associated molecules.
  • All AILT and ALCL showed a homogeneous effector cell phenotype (CD45RA(-)/CD45R0(+)/CD27(-)), but differed in the cytotoxic and activation markers expressed.
  • Several (5/8) PTCL-NOS clustered together; these cases all exhibited a CD4(+) central memory cell phenotype (CD45RA(-)/CD45R0(+)/CD27(+)) and four expressed the lymph node homing receptor CCR7.
  • In conclusion, AILT and ALCL tumour cells correspond to different subsets of effector cells, while a subset of PTCL-NOS correlates with a non-effector T-cell population.

  • Post-transplant lymphoproliferative disorder (PTLD) is a complication that can develop after either solid-organ or hematopoietic stem cell transplantation (HSCT).
  • T-cell PTLD is a rare disorder, especially following autologous HSCT.
  • Here we report a case of T-cell PTLD which occurred after autologous peripheral blood stem cell transplantation (PBSCT) for relapsed angioimmunoblastic T-cell lymphoma (AILT).
  • Our post-mortem study confirmed the marked proliferation of EBV-infected T-cells that differed from the original AILT clone and macrophages/histiocytes were observed in the marrow, liver, lymph nodes and lungs.
  • The patient's AILT remained in complete remission.
  • To the best of our knowledge, this is the first case of fulminant EBV-associated T-cell lymphoproliferative disorder (LPD) following autologous HSCT.

  • [Title] Epstein-Barr virus-positivity in tumor has no correlation with the clinical outcomes of patients with angioimmunoblastic T-cell lymphoma.
  • BACKGROUND/AIMS: Epstein-Barr virus (EBV) is involved in the pathogenesis of angioimmunoblastic T-cell lymphoma (AILT), but its precise role and prognostic impact are not clear.
  • This study aimed to evaluate the incidence of EBV-postitivity in the tumor and bone marrow (BM) samples from AILT patients, and their correlations with the clinical variables and patient survival.
  • METHODS: Seventy AILT cases were identified over a period of 8 years.
  • In 13 (48%) patients, gross tumor involvement was recognized by hematoxylin-eosin staining at the time of diagnosis.
  • CONCLUSIONS: EBV-positivity of tumor had no impact on the prognosis of AILT patients.

  • [Title] Monoclonality and oligoclonality of T cell receptor beta gene in angioimmunoblastic T cell lymphoma.
  • Angioimmunoblastic T cell lymphoma (AILT) is an aggressive T cell lymphoma with an incidence of approximately 1-2% of all non-Hodgkin lymphoma.
  • The detection of clonal T cell receptor (TCR) gene rearrangements helps in the diagnosis of T cell malignancies such as AILT, where morphological and immunohistological investigations are not always sufficient to reach a definitive diagnosis.
  • TCR beta (TCRB) and TCR gamma (TCRG) gene rearrangements were analysed from 17 WHO-defined cases of AILT by PCR for the presence of TCR clonality.
  • The results of this study emphasise that TCR clonality and oligoclonality is a diagnostic feature of AILT and that BV17S1 is over-represented with no other common molecular findings.

  • Four months after the auto-PBSCT, bilateral cervical lymphadenopathy developed.
  • Histopathological findings from a biopsied cervical lymph node showed angioimmunoblastic T-cell lymphoma (AILT).
  • The patient was treated with modified CVP therapy, and she is alive with no evidence of lymphoma five years after auto-PBSCT.
  • Clinical and histopathological findings showed that the FL and AILT in this case were not concomitant.
  • It is thought that in this case, the AILT developed as a post-transplant lymphoproliferative disorder after auto-PBSCT for the FL.

  • All angioimmunoblastic T-cell lymphoma (AILT) and subcutaneous panniculitis-like T-cell lymphoma (SPTCL) patients achieved CR; 5 of 6 have remained disease free for more than 3 years.
  • The patient with hepatosplenic lymphoma did not achieve CR even after PBSCT and underwent allogenic bone marrow transplantation (allo-BMT).
  • Thus, our regimen appears to be effective for high-risk AILT and SPTCL.
  • However, allo-BMT should be considered for high-risk of PTCLu and hepatosplenic T-cell lymphoma.

  • Epstein-Barr virus (EBV)-associated B-cell lymphoproliferative disorders occur at an increasing frequency in various hereditary and acquired states of immune dysfunction.
  • In a few cases of T-cell lymphoma, especially in angioimmunoblastic T-cell lymphoma (AILT), EBV-associated B-cell lymphoproliferative disorders have been reported.
  • Here, we present two cases of EBV-associated B-cell lymphoma after treatment of T-cell lymphoma (AILT and peripheral T-cell lymphoma, unspecified, PTCL-NOS) with a regimen containing alemtuzumab and fludarabine.
  • Conventional and immunohistological tissue staining showed the typical features of highly proliferating diffuse large B-cell lymphoma in both cases.
  • The monoclonal B-cell population displayed EBV latency type III.
  • At the time of diagnosis the cellular immune status of both patients was severely compromised with an absolute CD4 T-cell count below <120 microl(-1).
  • Our observation supports the notion that combination of cytotoxic drugs and immunosuppressive antibodies in patients with T-cell lymphoma may severely aggravate the already present immunodeficiency.
  • We suggest to monitor the cellular immune status in combination with the EBV load in high risk patients for early detection-and possibly intervention-of EBV-associated lymphoma.

  • [Title] Morphologic and immunophenotypic analysis of angioimmunoblastic T-cell lymphoma: Emphasis on phenotypic aberrancies for early diagnosis.
  • The morphologic features and immunophenotype of diagnostic nodal and bone marrow biopsy specimens were reviewed in 29 well-established cases of angioimmunoblastic T-cell lymphoma (AILT).
  • All cases showed a characteristic polymorphous lymphoid and inflammatory cell infiltrate along with stromal-vascular changes.
  • Unique architectural changes, including extranodal extension (83%), follicular dendritic cell proliferation (93%), and a distinctly marginalized distribution of residual B cells (67%) were observed.
  • Subsets of T cells with immunophenotypic abnormalities (CD10 coexpression or loss of pan-T-cell antigens CD3 and CD7) were identified in a majority of cases (96%).
  • Significantly, these morphologic and phenotypic features were seen irrespective of the presence of an overt lymphomatous pattern.
  • Our results indicate that unique morphologic alterations and subsets of phenotypically aberrant T cells are present consistently in nearly all cases of AILT, including morphologically less definitive biopsy specimens.

  • [Title] Evaluation of FoxP3 expression in peripheral T-cell lymphoma.
  • Peripheral T-cell lymphomas (PTCLs) are biologically heterogeneous and have not been successfully correlated with specific T-cell subsets.
  • We investigated PTCL, not otherwise specified (NOS), angioimmunoblastic T-cell lymphoma (AILT), and anaplastic large cell lymphoma (ALCL) cases for FoxP3 expression to determine a potential derivation from regulatory T (Treg) cells.
  • One PTCL-NOS case strongly expressed FoxP3 in the neoplastic T cells and showed unusual histomorphologic features with a dense infiltration of the lymph node by immunoblastic T cells and almost no reactive background infiltrate.
  • The patient died shortly after diagnosis, suggesting that biologic properties of Treg cells may have contributed to the rapidly fatal clinical course.
  • All remaining PTCL-NOS and AILT cases showed FoxP3 positivity only in the reactive infiltrate.
  • FoxP3+ PTCL-NOS presumably derived from bona fide Treg cells occurs but seems rare in the Western population.

  • We studied the clinico-pathologic features and treatment outcome of patients with peripheral T-cell lymphoma (PTCL).
  • This study included 215 patients with T/natural killer (NK)-cell lymphoma, including 59 with PTCL-unspecified (PTCL-U), 42 with angioimmunoblastic T-cell lymphoma (AILT) and 20 with anaplastic large-cell lymphoma (ALCL).
  • Most of the analyses were performed on patients with AILD, ALCL and PTCL-U.
  • The patients with AILT and PTCL-U tended to be older than those with ALCL.
  • Stage III/IV disease was seen in 90.5% of the AILT cases, 55% of the ALCL cases and 67.8% of the PTCL-U cases.
  • In addition, 61.9% of the AILT cases had an international prognostic index (IPI) of H-I or H risk.
  • The 5-year progression-free survival (PFS) and overall survival (OS) rates were 72.2 and 76.1% among the ALCL cases, 40.7 and 42.2% among the PTCL-U cases and 31.2 and 49.3% among the AILT cases, respectively.
  • The 5-year PFS and OS rates among patients who received CHOP therapy, CyclOBEAP [cyclophosphamide (CPA), vincristine (VCR), bleomycine, etoposide, doxorubicin (DXR), prednisone (PDN)] therapy or autologous stem cell transplantation were: 22 and 25.7%, 59 and 61.7% or 33.3 and 60%, respectively.

  • [Title] FDG-PET in T-cell and NK-cell neoplasms.
  • BACKGROUND: A growing number of studies demonstrate the utility of (18)fluoro-2-deoxyglucose positron emission tomography (FDG-PET) in the management of malignant lymphoma.
  • The results of FDG-PET, however, have not been studied extensively for T-cell and natural killer (NK)-cell neoplasms.
  • PATIENTS AND METHODS: We retrospectively evaluated pretreatment FDG-PET scans in 41 patients with T/NK-cell neoplasms diagnosed according to the World Health Organization (WHO) classification.
  • Histological subtypes frequently included were peripheral T-cell lymphoma, unspecified (PTCLu, n = 11), extranodal NK/T-cell lymphoma, nasal type (ENKL, n = 8), primary cutaneous anaplastic large cell lymphoma (C-ALCL, n = 5), and angioimmunoblastic T-cell lymphoma (AILT, n = 4).
  • RESULTS: FDG-PET detected a lymphoma lesion in at least one site in 36 out of 41 patients.
  • The positive rate was equally high in most histological subtypes except for cutaneous lymphomas: PTCLu 91%, ENKL 100%, C-ALCL 60%, AILT 100%.
  • CONCLUSION: T/NK-cell neoplasms incorporated in this study were generally FDG-avid except for cutaneous lesions and bone marrow involvement.

  • [Title] Clinicopathologic features and treatment outcome of mature T-cell and natural killer-cell lymphomas diagnosed according to the World Health Organization classification scheme: a single center experience of 10 years.
  • BACKGROUND: Data on mature T-cell and natural killer (NK)-cell lymphomas diagnosed with the World Health Organization (WHO) classification scheme are scarce.
  • METHODS: Consecutive T-cell and NK-cell lymphomas classified according to the WHO scheme within 10 years in a Chinese population were reviewed.
  • RESULTS: There were 148 cases, constituting 16.6% (T-cell, n=90, 10.1%, NK-cell, n=58, 6.5%) of all non-Hodgkin lymphomas in this period.
  • There was a male predominance (male:female = 2.5), young age at diagnosis (median age 50 years, range 8-86) and frequent extranodal presentation.
  • Commonest T-cell lymphomas included anaplastic large cell lymphoma (ALCL, n=25, median age 35 years, nodal 60%, stage I/II 60%), peripheral T-cell lymphoma, unspecified (PTCL, n=24, median age 54 years, nodal 42%, stage I/II 42%), and angioimmunoblastic T-cell lymphoma (AILT, n=19, median age 67 years, nodal 95%, stage I/II 26%).
  • Overall frequencies of T-cell lymphomas were comparable to Western patients.
  • AILT, PTCL and ALCL were aggressive with a poor outcome.
  • NK-cell lymphomas were predominantly extranodal (96%) and aggressive, with a frequency much higher than Western patients.
  • CONCLUSIONS: The apparent high prevalence of T-cell and NK-cell lymphomas in the Chinese was due to more frequent NK-cell but not T-cell lymphomas.

  • [Title] Powerful strategy for polymerase chain reaction-based clonality assessment in T-cell malignancies Report of the BIOMED-2 Concerted Action BHM4 CT98-3936.
  • Polymerase chain reaction (PCR) assessment of clonal T-cell receptor (TCR) and immunoglobulin (Ig) gene rearrangements is an important diagnostic tool in mature T-cell neoplasms.
  • To obtain reference values for Ig/TCR rearrangement patterns, 19 European laboratories investigated 188 T-cell malignancies belonging to five World Health Organization-defined entities.
  • TCR clonality was detected in 99% (143/145) of all definite cases of T-cell prolymphocytic leukemia, T-cell large granular lymphocytic leukemia, peripheral T-cell lymphoma (unspecified) and angioimmunoblastic T-cell lymphoma (AILT), whereas nine of 43 anaplastic large cell lymphomas did not show clonal TCR rearrangements.
  • Ig clonality was mostly restricted to AILT.
  • Our study indicates that the BIOMED-2 multiplex PCR tubes provide a powerful strategy for clonality assessment in T-cell malignancies assisting the firm diagnosis of T-cell neoplasms.
  • The detected TCR gene rearrangements can also be used as PCR targets for monitoring of minimal residual disease.

  • [Title] [Clinicopathologic study of 963 cases of mature T-cell and natural killer/T-cell lymphoma with respect to 2008 WHO classification of lymphoid neoplasms].
  • OBJECTIVE: To study the clinicopathologic features of various types of mature T-cell and natural killer (NK)/T-cell lymphoma in Guangdong, China, with respect to the 2008 WHO classification of lymphoid neoplasms.
  • METHODS: Eleven hundred and thirty-seven (1137) cases of mature T-cell or NK/T-cell lymphoma diagnosed during the period from 2002 to 2006 in Guangzhou area were retrieved.
  • RESULTS: Nine hundred and sixty-three (963) cases fulfilled the diagnostic criteria of mature T-cell or NK/T-cell lymphoma and accounted for 20.1% of all cases of lymphoma encountered during the same period (963/4801).
  • A predominance of extranodal involvement was noted in 644 cases (66.9%), while 319 cases (33.1%) showed mainly nodal disease.
  • The prevalence of various lymphoma subtypes was as follows: peripheral T-cell lymphoma, unspecified (PTCL, NOS) 293 cases (30.4%), extranodal NK/T-cell lymphoma, nasal type 281 cases (29.2%), anaplastic large cell lymphoma (ALCL) 198 cases (20.6%), and angioimmunoblastic T-cell lymphoma (AILT) 46 cases (4.8%).
  • The median age of the patients was 44 years, with the peak age of PTCL, NOS, extranodal NK/T-cell lymphoma, nasal type and AILT being 55 to 64 years, 25 to 54 years and 65 to 74 years, respectively.
  • CONCLUSIONS: Extranodal lesions predominate in mature T-cell and NK/T-cell lymphomas occurring in Guangzhou area.
  • The most common subtype was PTCL, NOS, followed by extranodal NK/T-cell lymphoma, nasal type, ALCL and AILT.
  • The relatively frequent occurrence of extranodal NK/T-cell lymphoma, nasal type in Guangdong area is likely associated with the high incidence of Epstein-Barr virus infection there.

  • Angioimmunoblastic T cell lymphoma is a distinct entity for which there is no standard therapy.
  • On the basis of the rationale that CsA may represent a novel drug for AITL, a disease with considerable immune dysregulation, and encouraging case reports, the authors have treated 12 patients with this agent.
  • Responding patients received a maintenance dose of 50 - 100 mg, with a gradual taper after a maximal response was achieved as tolerated.
  • By interrupting T-cell activation, CsA may alter the immune dysregulation that characterizes AILT.
  • The efficacy of CsA is being explored in patients with recurrent AILT in a prospective trial (ECOG 2402).

  • [Title] Peripheral T-cell lymphoma with involvement of the expanded mantle zone.
  • Peripheral T-cell lymphoma (PTCL) with a nodular architecture is rare.
  • Recently, two variants have been described with infiltration of the B-cell follicle, one variant that localizes to the marginal zone with a so-called perifollicular growth pattern, and a variant that localizes to the germinal center.
  • These lymphomas have a CD4+ phenotype and may express Bcl-6.
  • We have studied five similar cases of PTCL with involvement of the B-cell follicle.
  • However, our cases differ from the cases previously described by their predominant and frequently patchy involvement of the expanded mantle zone of the B-cell follicle at onset.
  • Later biopsies in three of the cases show diffuse infiltration of the lymph node, without features of angioimmunoblastic TCL (AILT).
  • Whether our cases are part of a spectrum of PTCLs that encompasses previously described variants with predominant marginal zone or germinal center infiltration or they represent a separate T-cell lymphoma type remains to be demonstrated by a study of more of such cases.

  • [Title] 'Normal counterparts' of nodal peripheral T-cell lymphoma.
  • Peripheral T-cell lymphomas (PTCL) have been difficult to classify.
  • A homogeneous principle of classification is still lacking, partly because lymph node compartments containing functionally distinct T-cell subsets have not been identified.
  • A correlation to differentiated T-cell subsets, as CD4(+) or CD8(+) cells as well as cytotoxic populations has not revealed clinically meaningful entities.
  • Immunohistological analysis of PTCL showed an effector or effector-memory cell phenotype (CD45RA(-)/CD45R0(+)/CD27(-)) for both angioimmunoblastic T-cell lymphoma (AILT) and anaplastic large cell lymphoma (ALCL), but different cytotoxic and activation markers expressed by these tumours.
  • A subset of CD4(+) PTCL-not otherwise specified (PTCL-NOS) may correspond to a central memory cell phenotype (CD45RA(-)/CD45R0(+)/CD27(+)).
  • A comparison between the lymphomas and their normal counterparts may contribute to the understanding of the underlying transformation mechanisms.

  • [Title] Pathobiology of peripheral T-cell lymphomas.
  • Peripheral T-cell lymphomas (PTLs) are uncommon, accounting for fewer than 10% of all non-Hodgkin lymphomas.
  • Success in therapy of the PTLs has lagged behind that of aggressive B-cell lymphomas, and most PTLs have a poor prognosis.
  • In the WHO classification, clinical features, in conjunction with morphological and immunophenotypic criteria, are relied on to define most disease entities.
  • Functionally, T-cell lymphomas are related to the two major arms of the immune system, the innate and adaptive immune systems.
  • The lymphomas derived from these cells often involve cutaneous and mucosal sites.
  • The expression of cytotoxic molecules in these lymphomas may predispose to apoptosis by tumor cells and normal bystander cells.
  • Hepatosplenic T-cell lymphoma is a systemic disease derived from functionally immature innate effector cells, most often of gammadelta T-cell origin.
  • In contrast, most nodal T-cell lymphomas belong to the adaptive immune system.
  • Angioimmunoblastic T-cell lymphoma (AILT) is mostly likely derived from follicular helper T-cells (T(FH)), a finding that explains many of its pathological and clinical features.

  • [Title] Tissue microarray-based screening for chromosomal breakpoints affecting the T-cell receptor gene loci in mature T-cell lymphomas.
  • The pathogenesis of mature T-cell non-Hodgkin lymphomas (T-NHLs) is poorly understood.
  • Analogous to B-cell lymphomas, in which the immunoglobulin (IgH) receptor loci are frequently targeted by chromosomal translocations, the T-cell receptor (TCR) gene loci are affected by translocations in a subset of precursor T-cell malignancies.
  • In a large-scale analysis of 245 paraffin-embedded mature T-NHLs, arranged in a tissue microarray format and using improved FISH assays for the detection of breakpoints in the TCRalpha/delta, TCRbeta, and TCRgamma loci, we provide evidence that mature T-NHLs other than T-cell prolymphocytic leukaemia (T-PLL) also occasionally show a chromosomal rearrangement that involves the TCRalpha/delta locus.
  • In particular, one peripheral T-cell lymphoma (not otherwise specified, NOS) with the morphological variant of Lennert lymphoma displayed a chromosomal translocation t(14;19) involving the TCRalpha/delta and the BCL3 loci.
  • A second case, an angio-immunoblastic T-cell lymphoma (AILT), carried an inv(14)(q11q32) affecting the TCRalpha/delta and IgH loci.
  • FISH signal constellations as well as concomitant comparative genomic hybridization (CGH) data were also suggestive of the occurrence of an isochromosome 7, previously described to be pathognomonic for hepatosplenic T-cell lymphomas, in rare cases of enteropathy-type T-cell lymphoma.

  • [Title] A multivariate analysis for the survival of nodal peripheral T-cell lymphoma (PTCL).
  • : e19521 Background: Nodal peripheral T-cell lymphoma (PTCL) is uncommon lymphoma with various subtypes and poor prognosis.
  • However, the superiority of high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) has remained inconclusive.
  • We conducted a retrospective study of fifty six patients with three major nodal PTCL, histologically classified as PTCL-not specified (NOS, n=29), angioimmunoblastic T-cell lymphoma (AITL, n=19), and ALK-negative anaplastic large cell lymphoma (ALCL, n=8) who underwent ASCT (n=14) or not (n=42) after CT in Tokai University Hospital, Ebina General Hospital, and Hadano Red Cross Hospital, Kanagawa, Japan between 1997 and 2008.
  • METHODS: Retrospective, multicenter cohort study by time-dependent or non-time-dependent multivariate survival analysis with Cox proportional hazard regression.
  • In non-time-dependent analysis, both ASCT and sIL-R were significant prognostic factors for overall survival (OS).
  • On the other hand, ASCT was only important effect on progression-free survival (PFS) by non-time-dependent analysis, which HR was 0.20 (95%CI: 0.07-0.55, p=0.02).

  • OBJECTIVE: Membranous (M) cell of the human palatine tonsil is an antigen entry site for mucosal infection, but its location is obscure in histological sections.
  • Recently, a microarray analysis has demonstrated that clusterin, annexin A5, CD44, MMP14, and beta-tubulin are candidate genes of M cell marker in mice.
  • Among these genes, we here describe class II beta-tubulin as a new marker for human tonsillar M cells and follicular dendritic cells (FDCs), and present its usefulness for diagnosis of angioimmunoblastic T-cell lymphomas (AILTs).
  • MATERIALS AND METHODS: Immunohistochemistry and Western blotting for class II beta-tubulin were performed using 81 cases of lymphoid, gastrointestinal and thyroid tissues, and an FDC cell line, respectively.
  • Immunoblot analysis revealed that class II beta-tubulin expression was upregulated in HK cells, a normal FDC cell line.
  • Thus, class II beta-tubulin immunostaining may be useful to identify tonsillar M cells and to diagnose FDC proliferative lesions such as AILT.

  • The association of Epstein-Barr virus (EBV) with human immunodeficiency virus-negative T-cell lymphoma was examined in 68 patients using the polymerase chain reaction (PCR) with DNA obtained from formalin-fixed paraffin-embedded tissues and an in situ hybridization technique.
  • EBV-encoded RNA (EBER) was detected in 43 of 68 cases (63%) of peripheral T-cell lymphoma: in 100% (11 of 11 cases) of NK/T-cell lymphomas, 70% (14 of 20 cases) of angioimmunoblastic T-cell lymphomas (AILT) and 49% (18 of 37 cases) of other types of peripheral T-cell lymphoma.
  • The 5-yr survival rate was 28% for peripheral T-cell lymphomas overall, 0% for NK/T-cell lymphomas, 38% for AILTs and 28% for other types of peripheral T-cell lymphoma.
  • The difference in the overall survival rate between NK/T-cell lymphoma and non-NK/T-cell lymphoma was significant (P = 0.0498 by Log-rank test).
  • Among peripheral T-cell lymphoma patients overall, the group severely infected with EBV (EBER-ISH ++) had a lower 5-yr survival rate (8%) than the group slightly (EBER-ISH +) or not infected (38%; P = 0.0013).

  • BACKGROUND: Cardiac tamponade (CT) as the primary clinical manifestation of lymphomas is extremely rare.
  • Angioimmunoblastic T-cell lymphoma (AILT) is characterised by systemic disease usually presenting with generalised peripheral lymphadenopathy, hepatosplenomegaly, and bone marrow infiltration.
  • CASE REPORT: We report on a 59-year-old male patient with CT as initial clinical manifestation of AILT.
  • Coexistence with malignant pleural mesothelioma was additionally revealed.
  • Cytologic examination of pericardial fluid presented diffuse lymphoid cells and sporadic malignant mesothelial cells.
  • AILT diagnosis was confirmed by thoracoscopic mediastinal lymph node and bone marrow biopsy.
  • Despite the presence of pleural effusion, the diagnosis of mesothelioma was initially established by cytologic ex-amination of pericardial fluid, due to the patient's critical cardiac condition requiring prompt subxiphoid pericardiocentesis.
  • CONCLUSION: CT as primary clinical manifestation of AILT is very rare.
  • This case reflects the differences in the underlying biology of AILT and consequently the vast spectrum of its clinical presentations.
  • Coexistence of AILT with malignant pleural mesothelioma is also extremely rare.

  • [Title] Follicular dendritic cell immunohistochemical markers in angioimmunoblastic T-cell lymphoma.
  • Angioimmunoblastic T-cell lymphoma is characterized by a paracortical proliferation of medium to large neoplastic T cells, often with clear cytoplasm, in a background of arborizing high endothelial venules, many surrounded by follicular dendritic cells (FDCs).
  • The authors stained a collection of 45 angioimmunoblastic T-cell lymphomas with CD21, CD23, CNA.42, cystatin A, and fascin for direct comparison of FDC staining characteristics in this setting.
  • CD21 highlighted the expected dendritic network of cell processes, within residual follicles and outside of follicles, often adjacent to proliferating vessels.
  • Cystatin A stained the cytoplasm of follicular dendritic cells within and outside of follicles; however, staining was often not sharply localized to dendritic cell processes, and scoring was further complicated by reactivity with other cell types in over half of the cases.
  • Likewise, fascin stained a variety of cell types, including strong staining of interdigitating dendritic-like cells, moderate staining of endothelial cells, and only weak staining of follicular dendritic cells within and outside of follicles.
  • Thus, CD21 remains the most reliable marker of follicular dendritic cells in angioimmunoblastic T-cell lymphoma.

  • Patients with angioimmunoblastic T-cell lymphoma can have profound immune dysfunction and immunodeficiency.
  • Epstein-Barr virus-driven B-cell lymphoid proliferation can occur in angioimmunoblastic T-cell lymphoma, as in other immunodeficiency states.
  • However, few cases of Epstein-Barr virus-positive B-cell lymphoma arising in patients with preexisting angioimmunoblastic T-cell lymphoma have been reported.
  • We report a case of angioimmunoblastic T-cell lymphoma in which diffuse large B-cell lymphoma developed 56 months after the diagnosis of angioimmunoblastic T-cell lymphoma.
  • The patient survived for 9 years after the initial diagnosis of angioimmunoblastic T-cell lymphoma, and molecular studies performed on multiple biopsy specimens during this period revealed the dynamic nature of clonal lymphoid expansion.
  • Epstein-Barr virus latent membrane protein 1 and Epstein-Barr virus-encoded RNA were detected in the diffuse large B-cell lymphoma, suggesting that Epstein-Barr virus may have played a role in the pathogenesis of the diffuse large B-cell lymphoma.

  • [Title] Peripheral T-cell lymphomas with a follicular growth pattern are derived from follicular helper T cells (TFH) and may show overlapping features with angioimmunoblastic T-cell lymphomas.
  • Rare cases of peripheral T-cell lymphomas with follicular growth pattern (PTCL-F) have been recently reported, and their association with t(5;9)(q33;q22) involving ITK and SYK has been suggested.
  • However, the clinicopathologic aspects of PTCL-F are poorly described and the normal cell counterpart of this subgroup of lymphoma is still unknown.
  • Patients with clinical data available had multiple lymphadenopathies (25/28, 89%), stage III to IV diseases (17/26, 65%), B symptoms (7/27, 26%), and skin lesions (6/23, 26%).
  • Three patients with sequential biopsies disclosed clinical and histopathologic features of angioimmunoblastic T-cell lymphoma at initial presentation.
  • Our results show that this rare form of PTCL-F (1) has an immunophenotype indicative of derivation from TFH cells, (2) is associated with t(5;9) in a proportion of cases, and (3) shows some overlapping features with angioimmunoblastic T-cell lymphoma, raising the question of a possible relationship.

  • OBJECTIVE: To study the morphologic and immunophenotypic features of angioimmunoblastic T-cell lymphoma (AITL), as well as the origin of the proliferative follicular dendritic cells (FDCs) in AITL.
  • Cases of peripheral T-cell lymphoma, unspecified, extranodal NK/T-cell lymphoma, nasal-type, enteropathy-type T-cell lymphoma, anaplastic large cell lymphoma, subcutaneous panniculitis-like T-cell lymphoma and reactive lymphoid proliferation were selected as controls.
  • RESULTS: Amongst the 29 cases of AITL studied, 75.9% (22/29) showed aberrant expression of CD10, while all except one of the controlled cases were negative, 82.8% (24/29) of the AITL cases expressed CXCL13, while all cases of peripheral T-cell lymphoma, unspecified were negative.
  • As for bcl-6 staining, although the highest percentage of bcl-6-positive cells was observed in AITL, the expression pattern was not useful in differentiating AITL from peripheral T-cell lymphoma, unspecified and lymphoid reaction.
  • Two of the cases, which contained obvious germinal centers, had the follicular dendritic cell meshwork extending beyond the lymphoid follicles.

  • [Title] Identification of circulating CD10 positive T cells in angioimmunoblastic T-cell lymphoma.
  • In most cases of lymphomas with blood dissemination, the careful cytological analysis of peripheral blood smears provides a rapid orientation to diagnosis, even if the final subtyping is achieved by histology and eventually other techniques.
  • Here, we evaluated if the analysis of blood smears may suggest the blood dissemination of angioimmunoblastic T-cell lymphoma (AITL) and if CD10 expression on neoplastic T cells, as recently reported on AITL, may contribute to the diagnosis.
  • In all, 11 lymph nodes and six peripheral blood samples from 12 patients with AITL were studied using four-colour flow cytometry associated to histological, cytological and molecular data.
  • Interestingly, all blood smears showed atypical lymphoid cells and a fraction of T cells expressed CD10 with a mean percentage of 18.75% (range 5.00-47.00%), regardless of lymphocytosis level and of rate of CD10 T cells in corresponding lymph node.
  • In contrast, in all control samples (100), none CD10-positive T cell was identified.
  • Therefore, they ought to be explored in further studies when aggressive lymphoma, in particular with lymphopenia and circulating atypical cells, is suspected.

  • [Title] Mast cells and Th17 cells contribute to the lymphoma-associated pro-inflammatory microenvironment of angioimmunoblastic T-cell lymphoma.
  • Reports focusing on the immunological microenvironment of peripheral T-cell lymphomas (PTCL) are rare.
  • Here we studied the reciprocal contribution of regulatory (Treg) and interleukin-17-producing (Th17) T-cells to the composition of the lymphoma-associated microenvironment of angioimmunoblastic T-cell lymphoma (AITL) and PTCL not otherwise specified on tissue microarrays from 30 PTCLs not otherwise specified and 37 AITLs.
  • We found that Th17 but not Treg cells were differently represented in the two lymphomas and correlated with the amount of mast cells (MCs) and granulocytes, which preferentially occurred in the cellular milieu of AITL cases.

  • [Title] Diffuse large B-cell lymphoma in patient after treatment of angioimmunoblastic T-cell lymphoma.
  • Relatively few cases of Epstein-Barr (EBV)-positive B-cell lymphomas arising in patients with angioimmunoblastic T-cell lymphoma (AITL) have been reported.
  • We report a case of AITL in which diffuse large B-cell lymphoma arose 13 months after the initial diagnosis of AITL.
  • In a 36-year-old female patient, evaluated for moderate leukocytosis, peripheral and abdominal lymphadenopathy AITL was diagnosed in March 2008, based on results of fine-needle aspiration cytology (FNAC) of the enlarged cervical and supraclavicular lymph nodes.
  • The diagnosis was also confirmed by immunophenotyping and histopathology of the cervical lymph nodes.
  • The patient initially recieved FED chemotherapy (fludarabine, cyclophosphamide, dexamethasone) followed by elective autologous hematopoietic stem cell transplantation.
  • In April 2009 the patient was hospitalized because of fever, pancytopenia, hyperbilirubinemia and peripheral lymphadenopathy.
  • CHOP-R chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab) was then administered, resulting in good partial response of the disease.
  • Reduced intensity allogeneic stem cell transplantation performed thereafter, resulted in complete remission of the disease.
  • AITL is a rare lymphoproliferative disorder in which the neoplastic T-cells represent the minority of the lymph node cell population and almost all cases harbor EBV-infected B-cells.
  • Various authors postulated that immunodeficiency in AITL patients together with immunosuppressive effects of cytotoxic drugs, may be responsible for EBV-induced proliferation of latently or newly EBV-infected B-cells with eventual clonal selection and progression to aggressive B-cell lymphoma.

  • [Title] Clinical, biologic, and pathologic features in 157 patients with angioimmunoblastic T-cell lymphoma treated within the Groupe d'Etude des Lymphomes de l'Adulte (GELA) trials.
  • To evaluate the prognostic significance of clinicobiologic and pathological features in angioimmunoblastic T-cell lymphoma (AITL), 157 AITL patients were retrieved from the GELA LNH87-LNH93 randomized clinical trials.
  • In multivariate analysis, only male sex (P = .004), mediastinal lymphadenopathy (P = .041), and anemia (P = .042) adversely affected overall survival.
  • In conclusion, AITL is a morphologically heterogeneous T-cell lymphoma commonly expressing CXCL13 and CD10 and carrying few prognostic factors.

  • [Title] [Clinicopathologic, immunohistochemical and molecular analysis in 15 cases of angioimmunoblastic T-cell lymphomas].
  • OBJECTIVE: To evaluate angioimmunoblastic T-cell lymphoma(AITL) completely, we gave injdepth investigation of histopathological features, specific immunochemical markers, antigen receptor gene rearrangements and in situ hybridization for Epstein-Barr virus (EBV).
  • Polymerase chain reaction for immunoglobulin heavy chain (IgH) and T cell receptor gamma (TCRgamma) rearrangements and in situ hybridization for Epstein-Barr virus encoded RNA (EBER-1) were performed.
  • CD21 expression exihibited extrafollicular expansion of follicular dendritic cell meshworks in 11 cases (73.3%), partially with a tendency of perivascular distribution.
  • Among the four cases with large B cell proliferation, three were EBV-positive.
  • Only when we recognize such diversity, can we reasonably apply and properly evaluate immunochemical markers and molecular techniques, and thus give a correct diagnosis.

  • [Title] The clonality of CD3+ CD10+ T cells in angioimmunoblastic T cell lymphoma, B cell lymphoma, and reactive lymphoid hyperplasia.
  • T cells coexpressing CD3 and CD10 are a characteristic feature of angioimmunoblastic T-cell lymphoma (AITL) [1].
  • However, they are not unique to AITL, as these cells are also present in B cell lymphoma and reactive lymphoid hyperplasia [2].
  • To determine the significance of CD3+ CD10+ T cells, we used flow cytometry with cell sorting and molecular biology techniques for T cell gene rearrangement to study T cells from patients with AITL, B cell lymphoma, and reactive lymph node hyperplasia.
  • We found that CD3+ CD10+ T cells in B cell lymphoma and reactive lymphoid hyperplasia were polyclonal.
  • These findings illustrate the differences between early and late lymphoma and could be important for the diagnosis of AITL.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Histological and immunophenotypical characteristics of peripheral T-cell lymphomas].
  • Histopathologic features of immunohistochemically confirmed 37 nodal peripheral T-cell lymphomas are described.
  • Unspecified and 10 angioimmunoblastic T-cell lymphomas were analyzed.
  • The most demonstrative histological features of both types of lymphomas were spectrum of small, medium and large lymphoid cells, lymphoid cells with irregular nuclei, presence of clusters of clear cells, arborizing endothelial venules, increased number of histiocytes, eosinophils and plasma cells.
  • Delineation between peripheral T-cell lymphoma, unspecified and angioimmunoblastic T-cell lymphoma needs evaluation of follicular dendritic cell pattern.
  • The results suggest that detection of histopathologic features typical for peripheral T-cell lymphomas gives an opportunity to compose optimal panel for immunotyping which is absolutely necessary.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Spectrum of bone marrow findings in patients with angioimmunoblastic T-cell lymphoma.
  • Bone marrow (BM) biopsy is often performed early in the evaluation of patients with angioimmunoblastic T-cell lymphoma (AITL), and may be the first diagnostic tissue sample; yet the BM histopathology associated with this disease has not been well described.
  • Seven (54%) were involved by AITL, which was characterised by paratrabecular and interstitial polymorphous infiltrates containing cytologically atypical lymphocytes, histiocytes and eosinophils.
  • As in lymph nodes, the lymphomatous infiltrate in some BMs contained numerous small or scattered large B cells, resembling either benign lymphoid aggregates or T cell rich large B cell lymphoma, respectively.
  • When BM biopsy preceded the diagnosis of AITL, these secondary changes were misinterpreted as chronic myeloproliferative disease (n = 2), or plasma cell dyscrasia (n = 2).
  • The spectrum of BM findings in AITL patients is important to recognise for early and accurate diagnosis in this disease.

  • [Title] [Analysis of overexpression of vascular endothelial growth factor-C in patients with angioimmunoblastic T-cell lymphoma].
  • OBJECTIVE: To explore the vascular endothelial growth factor-C (VEGF-C) expression and its clinical significance in malignant lymphoma.
  • METHODS: Lymphoma cells were isolated by laser microdissection.
  • VEGF-C expression in lymphoma tissue and microdissected lymphoma cells was measured by realtime quantitative PCR.
  • RESULTS: Comparing with that in 8 patients with reactive lymphocyte hyperplasia, VEGF-C was overexpressed in angioimmunoblastic T-cell lymphoma, both in lymphoma tissue (n = 18, P = 0.0020) and in microdissected lymphoma cells (n = 10, P < 0.0001).
  • CONCLUSION: The value of VEGF-C expression might be a biomarker of disease progression in angioimmunoblastic T-cell lymphoma.

  • [Title] Expression of CXCL13, a chemokine highly upregulated in germinal center T-helper cells, distinguishes angioimmunoblastic T-cell lymphoma from peripheral T-cell lymphoma, unspecified.
  • The germinal center T-helper cell has been proposed as the cell of origin for angioimmunoblastic T-cell lymphoma.
  • Our recent report of expression of CXCL13, a chemokine critical for germinal center formation and one of the most highly upregulated genes in the germinal center T-helper cell subset, in the majority of angioimmunoblastic T-cell lymphoma cases, provided further support for this theory.
  • To determine the specifity of this marker for angioimmunoblastic T-cell lymphoma, we evaluated CXCL13 expression in 26 nodal-based peripheral T-cell lymphomas and 14 lymph nodes showing paracortical lymphoid hyperplasia.
  • By WHO classification criteria, 20 of the lymphoma cases were considered peripheral T-cell lymphoma, unspecified, and six were reclassified as angioimmunoblastic T-cell lymphoma after immunohistochemical detection of disorganized follicular dendritic cell meshworks.
  • Combining the results of our studies, 31 of 35 angioimmunoblastic T-cell lymphoma cases (89%) showed CXCL13 expression, in contrast to two out of 20 peripheral T-cell lymphoma, unspecified cases (10%).
  • The two peripheral T-cell lymphoma, unspecified cases that were positive for CXCL13 showed a Lennert lymphoma-like histology.
  • While these cases did not meet all histologic criteria for angioimmunoblastic T-cell lymphoma, they did show an increase in EBV-positive B cells, suggesting they may be histologic variants of angioimmunoblastic T-cell lymphoma.
  • In conclusion, CXCL13 expression is a distinctive feature of angioimmunoblastic T-cell lymphoma, providing further support for the germinal center T-helper cell as the cell of origin for this neoplasm.
  • Given its specificity when compared to cases of peripheral T-cell lymphoma, unspecified as well as paracortical lymphoid hyperplasia, it may be a useful marker in the diagnosis of angioimmunoblastic T-cell lymphoma.

  • [Title] Molecular signatures to improve diagnosis in peripheral T-cell lymphoma and prognostication in angioimmunoblastic T-cell lymphoma.
  • Peripheral T-cell lymphoma (PTCL) is often challenging to diagnose and classify.
  • Gene expression profiling was performed on 144 cases of PTCL and natural killer cell lymphoma and robust molecular classifiers were constructed for angioimmunoblastic T-cell lymphoma (AITL), anaplastic lymphoma kinase-positive (ALK(+)) anaplastic large-cell lymphoma (ALCL), and adult T-cell leukemia/lymphoma.
  • Many of the pathologic features and substantial components of the molecular signature of AITL are contributed by the follicular dendritic cells, B-cell, and other stromal components.
  • The expression of Th17-associated molecules in ALK(+) ALCL was noted and may represent aberrant activation of Th17-cell differentiation by abnormal cytokine secretion.
  • Adult T-cell leukemia/lymphoma has a homogeneous molecular signature demonstrating high expression of human T-lymphotropic virus type 1-induced genes.

  • [Title] Angioimmunoblastic T-cell lymphoma in bone marrow: a morphologic and immunophenotypic study.
  • Angioimmunoblastic T-cell lymphoma is known to frequently involve bone marrow.
  • However, the histologic and immunophenotypic features of angioimmunoblastic T-cell lymphoma at this site are poorly defined.
  • We assessed 27 bone marrow specimens involved by angioimmunoblastic T-cell lymphoma from 20 patients.
  • Flow cytometry immunophenotyping revealed a CD3+CD10+ T-cell population in 2 (25%) of 8 cases assessed.
  • We conclude that the recognition and classification of angioimmunoblastic T-cell lymphoma in bone marrow are made difficult by the uncommon expression of CD10 (25%), rarity of follicular dendritic cells, and lack of CXCL13 expression at this site.
  • By contrast, programed death-1 immunohistochemical staining and double labeling using antibodies specific for BCL-6 and CD3 were helpful in appreciating the follicular T-helper cell immunophenotype of angioimmunoblastic T-cell lymphoma.

  • [Title] Angioimmunoblastic T-cell lymphoma: clinical and laboratory features at diagnosis in 77 patients.
  • We retrospectively analyzed 77 patients with pathologically diagnosed angioimmunoblastic T-cell lymphoma from a single city.
  • Average time between first symptoms of the disease and diagnosis was 3.6 months.
  • At diagnosis, peripheral nodes were present in all but 1 patient, and were generalized in 90% of cases.
  • Other clinical manifestations included pleuritis (22%); arthralgia or arthritis (17%); ear, nose, and throat involvement (14%); central or peripheral neurologic manifestations (10%); and ascites (5%).
  • Most patients presented with advanced disease at diagnosis (bone marrow involvement in 60% of cases).
  • Auto- or disimmune manifestations were reported in one-third of patients: autoimmune hemolytic anemia was present at diagnosis in 19% of patients and thrombocytopenic purpura in 7%.
  • Clonality was analyzed in lymph nodes in 47 patients: T-cell and B-cell clones were found in 45 (96%) and 20 (45%) patients, respectively.

  • [Title] Angioimmunoblastic T-cell lymphoma with hyperplastic germinal centres: a neoplasia with origin in the outer zone of the germinal centre? Clinicopathological and immunohistochemical study of 10 cases with follicular T-cell markers.
  • Angioimmunoblastic T-cell lymphoma is an aggressive peripheral T-cell lymphoma whose natural history is not fully understood.
  • The accurate recognition of Angioimmunoblastic T-cell lymphoma with pattern I remains a challenge and therefore the aim of this study is to phenotypically and morphologically characterize this variant with the use of the follicular helper T-cell (T(FH)) markers PD1, CXCL-13 and ICOS.
  • Out of the 88 Angioimmunoblastic T-cell lymphoma cases reviewed, 10 showed hyperplastic follicles.
  • Molecular probe methods for the detection of T-cell and B-cell clonality, as well as in-situ hybridization probes for EBV RNA expression, were carried out to leave no question as to the establishment of the diagnosis in each case.
  • By contrast, CD10 was found to only weakly label the neoplastic T cells, with only 5-10% of the target cell population staining for this marker.
  • Clinically, 8/9 cases presented with stage IIIB/IVB and in 2/10 cases consecutive biopsies showed 'progression' from pattern I to classical Angioimmunoblastic T-cell lymphoma.
  • In conclusion we have shown that the T(FH) cells markers PD1, CXCL13 and ICOS are useful adjuncts in the diagnosis of Angioimmunoblastic T-cell lymphoma with hyperplastic germinal centres.
  • PD1 also highlighted the presence of neoplastic cells in the outer zone of lymphoid follicles, suggesting that Angioimmunoblastic T-cell lymphoma (pattern I) may originate from T(FH) cells in this region, in accordance with previous immunological studies.
  • As the majority of cases in our series presented clinically with advanced stage disease, progression from pattern I to classical Angioimmunoblastic T-cell lymphoma may represent histological evolution rather than clinical progression.

  • To evaluate the clinical, pathological characters and prognosis of patients with angioimmunoblastic T cell lymphoma (AITL), the clinicopathologic features, immunophenotypes, therapy and survival rate of 12 AITL patients which were confirmed by pathologic examination were retrospectively studied.
  • The results indicated that main symptom was observed as general lymphadenopathy, however, 9 patients had fever.
  • The diagnosis of AITL was based on lymph-node biopsy.
  • The histopathologic characteristics of AITL showed the damage of normal lymphnode structure, the proliferation of immunoblastic cells and arborescent super vascularization.
  • All immunophenotypes were mature peripheral T-cellular.
  • In conclusion, most cases of AITL display an aggressive course, therefore, the disease progresses rapidly and has unfavorable prognosis, further studies are required to improve its therapy regimen.

  • [Title] Eosinophilic pleural effusion as the first presentation of angioimmunoblastic T cell lymphoma.
  • Eosinophilic pleural effusion (EPE), defined as pleural effusion that contains at least 10% eosinophils among the leukocytes, can be a manifestation of a great variety of diseases.
  • However, eosinophilia is a relatively rare finding in malignant pleural effusions, and it has been used as an indicator of good prognosis.
  • In clinical experience, very few cases of malignant lymphomas accompanied by EPE have been reported.
  • Pleural biopsy could not yield a definite diagnosis initially.
  • Six months later, bilateral neck, axillary and inguinal lymphadenopathy developed, and lymph node biopsy confirmed the diagnosis of angioimmunoblastic T cell lymphoma, with positive CD10 expression.
  • Therefore, we retrospectively carried out CD10 staining of the sample obtained from pleural biopsy and the positive result confirmed that the etiology of EPE was due to malignant T cell lymphoma.

  • OBJECTIVE: To study the value of immunomarkers CXCL13, CD10, bcl-6 in pathologic diagnosis of angioimmunoblastic T-cell lymphoma (AITL).
  • METHODS: One hundred and fifteen cases of AITL, 30 cases of peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS) and 30 cases of reactive lymph nodes with paracortical hyperplasia (RH) encountered during the period from January, 1990 to January, 2008 were retrieved from the archival files of the Department of Pathology, West China Hospital of Sichuan University, China.
  • The morphologic features were reviewed and compared.
  • RESULTS: Regressed follicles were evident in 7.8% (9/115) of AITL cases, 6.7% (2/30) of PTCL, NOS cases and 83.3% (25/30) of RH cases, respectively.
  • A marked increase of number of arborizing venules was shown in 98.3% (113/115) of AITL cases, 63.3% (19/30) of PTCL, NOS cases and 76.7% (23/30) of RH cases, respectively.
  • In AITL, 96.5% (111/115) of cases showed CXCL13 expression, in contrast to 26.7% (8/30) of PTCL, NOS.
  • Expression of CD10 and bcl-6 were found in the neoplastic cells in 50.4% (58/115) and 78.3% (90/115) of AITL, and 3.3% (1/30) and 3.3% (1/30) of PTCL, NOS, respectively.
  • CONCLUSIONS: AITL is a type of lymphoma originated from the follicular helper T cells.
  • Detailed morphologic assessment and use of immunohistochemical markers are essential for accurate diagnosis.

  • OBJECTIVE: To retrospectively analyze the clinical features and prognostic factors of patients with angioimmunoblastic T-cell lymphoma (AITL).
  • All of the patients received CHOP-like regimens as initial chemotherapy, including 4 once treated with radiotherapy and 1 with high dose therapy followed by autologous stem cell transplantation (HDT-ASCT) as upfront consolidation therapy.
  • B-cell, T-cell and NK-cell subgroup proportions in the peripheral blood were tested by flow cytometry in 6 patients.
  • With the median follow-up of 26 months, the overall 2-year survival and disease free survival (DFS) rates were 62.2% and 44.4%, respectively.
  • In the univariate analysis, only age > 30 years and primary refractory disease adversely affected overall survival (OS); age > 30 years, advanced stage, B symptoms and splenomegaly adversely affected DFS.
  • Flow cytometry of peripheral blood lymphocytes showed that 5 of the 6 tested cases had decreasing proportion of CD3(+)CD4(+) T cells, B cells and NK cells but elevated CD3(+)CD8(+) T cells.
  • Two heavily treated patients achieved partial and complete response by thalidomide therapy, with a progression free survival (PFS) of 2 and 6+ months, respectively.
  • Peripheral blood lymphocytes test indicates that AITL patients suffered from both natural and acquired immune defects.

  • [Title] In angioimmunoblastic T-cell lymphoma, neoplastic T cells may be a minor cell population. A molecular single-cell and immunohistochemical study.
  • The significance of T-cell proliferations in angioimmunoblastic lymphoma (AILD) is still enigmatic.
  • Although classified as a malignant T-cell lymphoma in the World Health Organisation lymphoma classification, some cases of AILD lack dominant T-cell clones.
  • In a previous study, based on single-cell polymerase chain reaction (PCR), we obtained similar results as studies of AILD using Southern blot or conventional PCR: some cases of AILD contained large T-cell clones, and, in other cases, T-cell clones were undetectable.
  • As in single-cell studies, only a limited number of cells could be investigated; thus, we wanted to gain more insight into the amount and distribution of tumour cells.
  • By applying triple immunofluorescent staining with antibodies directed against T-cell receptor Vbeta-family-specific epitopes, we investigated T-cell populations in AILD and their localisation in the tissue in relation to B cells (CD20) and follicular dendritic cells (CD21).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] CD10 expression in peripheral T-cell lymphomas complicated by a proliferation of large B-cells.
  • CD10 expression by the neoplastic T cells in angioimmunoblastic T-cell lymphoma was recently described.
  • As cases of peripheral T-cell lymphoma, unspecified, fail to show similar CD10 expression, this feature helps discriminate between these two entities, particularly in cases exhibiting morphologic overlap.
  • Given these findings, we studied CD10 expression in a subtype of peripheral T-cell lymphoma known as peripheral T-cell lymphoma complicated by a proliferation of large B cells and compared it with angioimmunoblastic T-cell lymphoma and angioimmunoblastic T-cell lymphoma with a large B-cell proliferation.
  • A total of 33 cases were identified including peripheral T-cell lymphoma complicated by a proliferation of large B cells (10), angioimmunoblastic T-cell lymphoma (10) and angioimmunoblastic T-cell lymphoma with a large B-cell proliferation (13).
  • Diagnoses were established by hematoxylin and eosin (H&E) stain, immunohistochemistry and/or molecular findings (polymerase chain reaction for T-cell receptor-gamma gene rearrangement).
  • Two of 10 cases of peripheral T-cell lymphoma complicated by a proliferation of large B cells showed aberrant CD10 expression (20%) compared to 9/10 cases of angioimmunoblastic T-cell lymphoma (90%) and 8/13 of angioimmunoblastic T-cell lymphoma with a large B-cell proliferation (62%).
  • One case each of angioimmunoblastic T-cell lymphoma and angioimmunoblastic T-cell lymphoma with a large B-cell proliferation showed a rare, but not unequivocal, CD10+ atypical cell.
  • Four cases of angioimmunoblastic T-cell lymphoma with a large B-cell proliferation were CD10 negative.
  • Of the 2 CD10+ peripheral T-cell lymphoma complicated by a proliferation of large B cells, one had no H&E or IHC features of angioimmunoblastic T-cell lymphoma and showed only a rare positive cell.
  • The second case, a lung biopsy, exhibited diffuse CD10 tumor cell positivity.
  • Our data indicate that only 20% of cases of peripheral T-cell lymphoma complicated by a proliferation of large B cells show CD10 expression by the neoplastic T cells in contrast to angioimmunoblastic T-cell lymphoma and angioimmunoblastic T-cell lymphoma with a large B-cell proliferation which exhibit CD10 staining in 90 and 62% of cases, respectively.

  • Angioimmunoblastic T-cell lymphoma (AITL) is a distinct peripheral T-cell lymphoma (PTCL) entity with peculiar clinical and pathological features.
  • The recent identification of follicular helper T (T(FH)) cell as the cell of origin of this neoplasm represents a major step in our understanding of the pathobiological characteristics of the disease and should, in the future, clarify the diagnostic criteria for AITL and help to delineate its spectrum, especially from PTCL, not otherwise specified (PTCL, NOS).
  • Deciphering the pathogenesis of the disease is needed to identify targets for new therapies that are expected to improve the poor outcome of AITL patients, when treated with conventional chemotherapy regimens.

  • We describe a 66-year-old man initially diagnosed with primary cutaneous marginal zone B-cell lymphoma who developed four additional monoclonal/monotypic B-cell lymphoid proliferations and a systemic angioimmunoblastic T-cell lymphoma over the course of 19 months.
  • Through retrospective analysis, we identified the evolution of a T-cell clone within the background of clinically and pathologically dominant cutaneous B-cell tumors.
  • In terms of clinical practice, this case supports that patients diagnosed with multiple clonal B-cell proliferation need thorough investigation and close clinical follow up to identify a coexistent or evolving systemic lymphoma, in particular, peripheral T-cell lymphomas of follicular T-helper cell type, such as angioimmunoblastic T-cell lymphoma.
  • Biologically, this case offers unique insight into the interactions between B-cell and T-cell lineages in lymphoid neoplasia.

  • [Title] Regulatory T-cell depletion in angioimmunoblastic T-cell lymphoma.
  • Angioimmunoblastic T-cell lymphoma (AITL) is the most frequent nodal T-cell lymphoma and is characterized by a polymorphic lymph node infiltrate, various dysimmune disorders, and a poor prognosis.
  • Regulatory T-cells (Treg) play an emerging role in the prognosis of non-Hodgkin B-cell lymphoma and mediate significant autoreactive T-cell suppression.
  • In this report, we demonstrate that numbers of Treg are significantly decreased in AITL lymph nodes [n = 30, 91 (40-195) per high power fields] compared with follicular lymphoma [n = 19, 179 (86-355)] and reactive lymph nodes [n = 8, 186 (140-265)].
  • Moreover, the few Treg in lymph nodes of AITL are resting Treg (rTreg) and have a naive CD45RA+, PD1-, and ICOS- phenotype [n = 5, 57% of Treg are CD45RA+ (16-96)], in contrast to the Treg in follicular lymphomas [n = 5, 7.4% (1-13)] or reactive lymph nodes [n = 7, 18.6% (6-48)].
  • Interestingly, Treg depletion was not observed in AITL peripheral blood at diagnosis.

  • [Title] Therapy of peripheral T/NK neoplasms.
  • The mature T/natural killer (NK) lymphoma/leukemias represent 5-15% of all non-Hodgkin lymphoma.
  • These diseases have a geographic variation, with more nodal disease in North America and Europe, including peripheral T cell lymphomas, unspecified, anaplastic large cell lymphoma, and angioimmunoblastic T cell lymphoma; and more extranodal disease in Asia due to Epstein-Barr virus-related nasal NK/T lymphoma and human T-cell leukemia virus (HTLV)-1-associated adult T cell leukemia/lymphoma.
  • The prognosis in most peripheral T/NK neoplasms is poor, with 5-year survival less than 30%.
  • Progress has been slow due to the rarity of the diseases, geographic variation, relative chemoresistance, and lack of randomized trials.
  • In this review, topics include the question of CHOP as standard therapy, prognostic factors, disease-adapted therapy, novel approaches, monoclonal antibody therapy, and stem cell transplantation.

  • [Title] Expression of two markers of germinal center T cells (SAP and PD-1) in angioimmunoblastic T-cell lymphoma.
  • BACKGROUND AND OBJECTIVES: In the present paper we report that SAP, an intracytoplasmic molecule that is involved in cell signaling, is an immunohistologic marker for germinal center T cells in paraffin-embedded tissue.
  • We document its expression, and also that of PD-1 (another recently described marker of germinal center T cells to which a new antibody has been raised), in normal and neoplastic lymphoid tissue to evaluate the suggestion that helper T cells within the germinal centers of human lymphoid tissue are the cell of origin of angioimmunoblastic T-cell lymphoma (AITL), and to assess the diagnostic value of these two markers.
  • DESIGN AND METHODS: Expression of SAP and PD-1 was investigated by immunohistochemistry in paraffin-embedded tissue sections and in cell lines.
  • Western blotting was performed on cell lines, and antibody specificity was confirmed by immunostaining of transfected cells.
  • RESULTS Screening on more than 500 lymphoma biopsies showed that 95% (40/42) of cases of AITL expressed at least one of these markers.
  • However, PD-1 and SAP were also found in a minority of cases of peripheral T-cell lymphoma other than AITL, in contrast to a report that the former marker is specific for AITL.
  • This observation raises the possibility that such non-angioimmunoblastic cases may be related to germinal center helper T cells.
  • They may also prove of value in the diagnosis of this disease since a negative reaction was rarely observed in this disorder.

  • [Title] Comparison of peripheral T-cell lymphomas and diffuse large B-cell lymphoma.
  • BACKGROUND: Peripheral T-cell lymphomas (PTCLs) are a biologically heterogeneous subgroup of lymphomas with poor prognosis.
  • In this study, the authors analyzed the clinical behaviors of PTCLs and diffuse large B-cell lymphoma (DLBCL).
  • METHODS: The authors compared the characteristics and outcomes of 59 patients with PTCLs, including 33 angioimmunoblastic T-cell lymphomas and 26 unspecified peripheral T-cell lymphomas, with the characteristics and outcomes of 193 patients with DLBCLs who were treated in the era before rituximab.
  • The 5-year overall survival (OS), progression-free survival (PFS), and disease-free survival (DFS) rates were 31%, 26%, and 47%, respectively, in patients with PTCLs and 59%, 55%, and 73%, respectively, in patients with DLBCL (P = .001, P < .001, and P = .003, respectively).
  • T-cell phenotype itself did not appear to have a significant impact on either response or survival.

  • [Title] The 2008 WHO classification of lymphomas: implications for clinical practice and translational research.
  • Recent studies have drawn attention to the biological overlap between classical Hodgkin lymphoma (CHL) and diffuse large B-cell lymphomas (DLBCL).
  • Similarly, there is a greater appreciation of the borderlands between Burkitt lymphoma and DLBCL.
  • Among the peripheral T-cell lymphomas (PTCL), more precise definitions were introduced for several entities, including anaplastic large cell lymphoma, angioimmunoblastic T-cell lymphoma, enteropathy-associated T-cell lymphoma, and subcutaneous panniculitis-like T-cell lymphoma.
  • Several new variants of primary cutaneous T-cell lymphomas are proposed.
  • Finally, the subclassification and categorization of the most common lymphoma subtypes, follicular lymphoma (FL) and DLBCL, were altered to enhance diagnostic accuracy and aid in clinical management.

  • [Title] The gene expression profile of nodal peripheral T-cell lymphoma demonstrates a molecular link between angioimmunoblastic T-cell lymphoma (AITL) and follicular helper T (TFH) cells.
  • The molecular alterations underlying the pathogenesis of angioimmunoblastic T-cell lymphoma (AITL) and peripheral T-cell lymphoma, unspecified (PTCL-u) are largely unknown.
  • The molecular profile of AITLs was characterized by a strong microenvironment imprint (overexpression of B-cell- and follicular dendritic cell-related genes, chemokines, and genes related to extracellular matrix and vascular biology), and overexpression of several genes characteristic of normal follicular helper T (T(FH)) cells (CXCL13, BCL6, PDCD1, CD40L, NFATC1).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Class III beta-tubulin shows unique expression patterns in a variety of neoplastic and non-neoplastic lymphoproliferative disorders.
  • In Hodgkin lymphomas (HLs), 47.1% (40/85) expressed TUBB3 in the tumor cells with an all-or-none pattern.
  • TUBB3 expression in HL was more common in mixed cellularity type than nodular sclerosis type (P=0.032).
  • Among non-HLs, 79.3% (23/29) of anaplastic large cell lymphoma (ALCL), 8% (2/25) of extranodal natural killer/T-cell lymphoma, and 75% (21/28) of Burkitt lymphoma showed TUBB3 expression with an all-or-none pattern.
  • Of diffuse large B-cell lymphoma, 15.2% (32/210) expressed TUBB3 in a heterogeneous pattern.
  • Diffuse large B-cell lymphomas with a germinal center B-like subgroup exhibited TUBB3 expression more frequently than non-GCB-like subgroup (P=0.01).
  • Otherwise, none of the 18 angioimmunoblastic T-cell lymphomas; 18 peripheral T-cell lymphomas, not otherwise specified; 12 follicular lymphomas; 62 marginal zone lymphomas; 7 mantle cell lymphomas; 8 small lymphocytic lymphomas; or 2 FDC sarcomas expressed TUBB3.
  • In angioimmunoblastic T-cell lymphoma and Castleman disease, TUBB3 was positive in immunoblasts corresponding to Epstein-Barr virus-infected or Kaposi sarcoma herpes virus-infected cells.
  • A variety of neoplastic and non-neoplastic lymphoproliferative disorders exhibited characteristic TUBB3 expression patterns; these results suggest potential for diagnostic utility, some insight into the pathobiology of TUBB3 expression, and potential therapeutic implications.

  • [Title] Allogeneic stem cell transplantation is able to induce long-term remissions in angioimmunoblastic T-cell lymphoma: a retrospective study from the lymphoma working party of the European group for blood and marrow transplantation.
  • PURPOSE: To analyze the long-term outcome in terms of nonrelapse mortality (NRM), relapse rate (RR), progression-free survival (PFS), and overall survival (OS) in patients with angioimmunoblastic T-cell lymphoma (AITL) treated with allogeneic stem-cell transplantation (alloSCT).
  • Median age was 48 years (range, 23 to 68 years), 34 patients had received > or = two lines of chemotherapy before alloSCT, and 11 patients had experienced treatment failure with a prior autologous stem-cell transplantation.
  • Twenty-seven patients were allografted in chemotherapy-sensitive disease, and 18 were allografted in refractory disease.
  • RR was estimated as 16% and 20% at 2 and 3 years, respectively, and was lower in patients developing chronic graft-versus-host disease (cGVHD).
  • Both the lower RR after transplantation as well as the decreased RR in patients developing cGVHD after the alloSCT suggests the existence of a clinically relevant graft-versus-lymphoma effect.
