[Title] A case report of Merkel cell carcinoma on chronic lymphocytic leukemia: differential diagnosis of coexisting lymphadenopathy and indications for early aggressive treatment.

BACKGROUND: Chronic lymphocytic leukemia (CLL) is a monoclonal disorder, characterized by a progressive proliferation of functionally incompetent B lymphocytes.

There is increased evidence of association between CLL and skin cancers, including the uncommon Merkel cell carcinoma (MCC).

During the recurrences of MCC, coexisting regional lymphadenopathy, posed a problem in the differential diagnosis and treatment of lymph node involvement.

Histopathology and immunoistochemistry showed that submandibular lymphadenopathy coexisting with the second recurrence of MCC, was due to B-cell small lymphocytic lymphoma.

The subsequent and more aggressive recurrence of the skin tumor had involved the superficial and deep cervical lymph nodes.

CONCLUSION: MCC has a high incidence of regional lymphadenopathy at presentation (12-45%) and even when it arises on the background of chronic leukemia, lymphadenopathy at presentation should be managed agressively with elective lymph node dissection.

We overview the postulated correlation between Merkel tumor and CCL, the differential diagnosis of regional lymphadenopathy during the recurrences of the skin tumor and the strategies of treatment.

[Title] Molecular imaging of bcl-2 expression in small lymphocytic lymphoma using 111In-labeled PNA-peptide conjugates.

The bcl-2 gene is overexpressed in non-Hodgkin's lymphoma (NHL), such as small lymphocytic lymphoma (SLL), and many other cancers.

In vitro studies were performed in Mec-1 SLL cells, which express both bcl-2 messenger RNA and somatostatin receptors.

Biodistributions and microSPECT/CT studies were performed in Mec-1-bearing SCID (severe combined immunodeficiency) mice, a new animal model of human SLL.

CONCLUSION: A new (111)In-labeled antisense PNA-peptide conjugate demonstrated proof of principle for molecular imaging of bcl-2 expression in a new mouse model of human SLL.

[Title] Initial diagnosis of small lymphocytic lymphoma in parotidectomy for Warthin tumour, a rare collision tumour.

Warthin tumours (WT) and malignant lymphomas are only rarely associated, and most are examples of involvement of the lymphoid stroma of WT by a disseminated lymphoma.

This report describes a case where excision of a parotid mass led to the initial diagnosis of WT and small lymphocytic lymphoma (SLL).

The diagnosis of SLL was confirmed by immunohistochemistry and molecular studies.

This case highlights the extremely rare association of SLL with WT and the importance of evaluation of the WT stroma, where the pale proliferation centres of SLL may mimic germinal centres of reactive lymphoid nodules.

[Title] Dietary factors and risk of chronic lymphocytic leukemia and small lymphocytic lymphoma: a pooled analysis of two prospective studies.

BACKGROUND: Other than male sex, family history, advanced age, and race, risk factors for chronic lymphocytic leukemia and small lymphocytic lymphoma (CLL/SLL) are unknown.

METHODS: Using two large prospective population-based studies, we evaluated the relationship between diet and CLL/SLL risk.

Among 525,982 men and women free of cancer at enrollment, we identified 1,129 incident CLL/SLL cases during 11.2 years of follow-up.

RESULTS: We found no associations between total fat, saturated fat, fiber, red meat, processed meat, fruit, or vegetable intake and risk of CLL/SLL.

We noted a suggestive positive association between body mass index and CLL/SLL (hazard ratio, 1.30; 95% confidence interval, 0.99-1.36).

CONCLUSION: We did not find any associations between food or nutrient intake and CLL/SLL.

IMPACT: Our large prospective study indicates that diet may not play a role in CLL/SLL development.

[Title] Programmed death 1 is a marker of angioimmunoblastic T-cell lymphoma and B-cell small lymphocytic lymphoma/chronic lymphocytic leukemia.

PD-1 expression was recently reported in some T-cell non-Hodgkin lymphoma (NHL) subtypes, but the expression profile of PD-1 and its ligands (PD-L1 and PD-L2) in B-NHLs remains largely to be characterized.

A series of 161 lymphoma tissue and 11 blood samples was analyzed using either immunohistochemistry or flow cytometry.

In reactive lymph nodes, PD-1 was mainly expressed in follicular T cells.

In B-NHLs, PD-1 was mainly expressed in reactive T cells; but expression was also noted in neoplastic B cells from small lymphocytic lymphoma (SLL, 12/13), grade III follicular lymphoma (3/3), and diffuse large cell lymphoma (2/25).

In contrast, neoplastic B cells from mantle cell lymphoma (0/11), marginal zone lymphoma (0/12), Burkitt lymphoma (0/3), and grade 1 to 2 follicular lymphoma (0/40) were PD-1 negative.

PD-L1 and PD-L2 were negative in small B-cell lymphomas, including B-SLL.

Flow cytometry showed that blood cells from chronic lymphocytic leukemia (B-CLL) also displayed PD-1 expression, which could be increased by CD40 stimulation.

These results show that PD-1 expression among B-NHLs is mainly associated with SLL/CLL and is influenced by activation of the CD40/CD40L pathway.

Because the anti-PD-1.6.4 antibody works on paraffin sections, it represents a useful tool to differentiate SLL/CLL from other small B-cell lymphomas.

[Title] Chromosomal abnormalities detected by multicolor fluorescence in situ hybridization in fine-needle aspirates from patients with small lymphocytic lymphoma are useful for predicting survival.

BACKGROUND: Fine-needle aspiration (FNA) of lymph nodes is commonly used to assess disease progression in patients with small lymphocytic lymphoma (SLL).

Although cytologic features are helpful for diagnosing typical SLL and transformed large-cell lymphoma (tLCL), SLL in accelerated phase (SLLacc) is more difficult to diagnose.

Additional tests are needed to identify those patients who are transforming to a higher-grade lymphoma.

This study evaluated the use of a multicolor fluorescence in situ hybridization (FISH) probe panel specifically designed for chronic lymphocytic leukemia (CLL)/SLL and assessed the association between FISH findings and cytologic diagnosis, proliferation index, and risk of death.

METHODS: FNA specimens from 50 patients (32 men and 18 women; mean age, 57 years [range, 36-77 years]) with histologically confirmed CLL and/or SLL were evaluated in this study for chromosomal abnormalities of 11q22 (ATM), 12, 13q14.3, 13q34.3 (LAMP1), and 17p13.1 (p53) by using a multiprobe FISH kit.

The FISH findings were compared with the cytologic diagnoses (26 SLLs, 12 SLLaccs, and 11 tLCLs), Ki-67 immunostaining, and risk of death.

CONCLUSIONS: FISH can be performed on FNA specimens from patients with a history of SLL/CLL.

Knowledge of genetic abnormalities from FNAs may be useful in deciding when and how to treat indolent or progressive SLL.

[Title] Multiple lymphomatous polyposis associated with small lymphocytic lymphoma: a unique presentation.

Multiple lymphomatous polyposis (MLP) is a rare extra-nodal manifestation of lymphoma.

In most cases, MLP is associated with mantle cell lymphoma (MCL).

We report a 66-year-old male diagnosed with small lymphocytic lymphoma (SLL)/chronic lymphocytic lymphoma (CLL), who showed evidence of rectal bleeding.

A CT-scan of the abdomen and pelvis showed an enlarged spleen, multiple paraaortic and mesenteric lymph nodes, and some diverticular pouching along the antimesenteric border of the pelvic colon.

A colonoscopy revealed the presence of multiple polypoid lesions, biopsies of which showed diffuse lymphoid infiltrate without any identifiable follicles.

Immunohistochemical analysis combined with a Fluorescence In-Situ Hybridization (FISH) study excluded the diagnosis of MCL.

A bone marrow aspiration biopsy demonstrated diffuse infiltration of the bone marrow with low grade lymphocytes that expressed CD 20, CD5 and CD23, with negative BCL-1, t (11;.

A diagnosis of B-cell CLL with kappa light chain restriction was made.

Multiple lymphomatous polyposis is considered to be a digestive counterpart to MCL and can therefore be considered as a presentation of MCL.

The patient's bone marrow revealed a B-cell lymphoma of CLL/SLL phenotype, which to our knowledge has not been linked to MLP in previously reported cases.

[Title] Micronodular T-cell/histiocyte-rich B-cell lymphoma of the spleen in a case of small lymphocytic lymphoma: a Richter's transformation.

Abstract A case of micronodular T-cell/histiocyte-rich B-cell lymphoma of the spleen who had a prior diagnosis of small lymphocytic lymphoma is presented.

Micronodular T-cell/histiocyte-rich B-cell lymphoma of the spleen was first described in 2003, and very few cases have been reported since then.

This is the first reported case supervening in a patient with pre-existing chronic lymphocytic lymphoma.

We review its clinical, pathologic, and immunohistochemical features and the difficulties we encountered during diagnosis.

[Title] High expression of the inhibitory receptor BTLA in T-follicular helper cells and in B-cell small lymphocytic lymphoma/chronic lymphocytic leukemia.

B- and T-lymphocyte attenuator (BTLA) is a lymphoid receptor that inhibits lymphocyte activation on interaction with its ligand, herpesvirus entry mediator (HVEM).

In reactive lymph nodes, they were both expressed in interfollicular T cells and in B cells from mantle and marginal zones.

BTLA was strongly expressed in chronic lymphocytic leukemia/small lymphocytic lymphoma (B-CLL/SLL, 19 of 19 positive) when compared with other small B-cell lymphomas, including follicular lymphoma (0 of 24 positive), mantle cell lymphoma (0 of 10 positive), and marginal zone lymphoma (0 of 5 positive).

Our results suggest that down-regulation of the BTLA-HVEM pathway may be involved in germinal center B-cell activation.

The specific high expression of BTLA in B-CLL/SLL represents a new potential diagnostic tool.

[Title] Indolent lymphomas of mature B lymphocytes.

The lymphomas of small B lymphocytes are a biologically diverse group of B cell derived neoplasms that includes B cell small lymphocytic lymphoma/chronic lymphocytic leukemia; mantle cell lymphoma; follicular lymphoma; nodal, splenic and extranodal marginal zone lymphomas; and lymphoplasmacytic lymphoma.

This article reviews the essential diagnostic and biologic features of these clinically indolent B cell malignancies.

[Title] Simultaneous occurrence of peripheral T-cell lymphoma unspecified and B-cell small lymphocytic lymphoma. Report of 2 cases.

We report on 2 composite lymphomas occurring in elderly patients, morphologically characterized by the combination of peripheral T-cell lymphoma (PTCL) unspecified and B-cell small lymphocytic lymphoma.

Immunohistochemistry provided objective confirmation of the coexistence of the 2 malignancies, as did molecular biology by revealing clonal T-cell receptor gamma and immunoglobulin heavy chain gene rearrangements.

One of the patients had no history of indolent lymphoma either at the personal and family level, whereas the other showed a strong familial predisposition, his mother and sister having suffered from B-cell chronic lymphocytic leukemia.

To the best of our knowledge, the simultaneous occurrence of PTCL unspecified and B-cell small lymphocytic lymphoma is an exceptional event; the possible pathogenetic correlations between the 2 neoplasms are discussed.

[Title] Frequencies of non-Hodgkin's lymphoma subtypes in Kuwait: comparisons between different ethnic groups.

There is a wide variation in the prevalence of various subtypes of non-Hodgkin's lymphoma worldwide.

The aim of this study was to determine the relative frequency of different subtypes of non-Hodgkin's lymphoma in Kuwait based on the Revised European-American Lymphoma (REAL) classification.

From 1998 to 2006, 738 subjects were included that were registered with non-Hodgkin's lymphoma in the population-based cancer registry at the Kuwait Cancer Control Center.

We performed detailed immunohistochemical studies and classified subjects based on the REAL classification.

The prevalence of different types of non-Hodgkin's lymphoma was determined based on age, sex, site of disease, and ethnicity.

The prevalence of B- and T-cell lymphomas was 81.8% and 14.2%, respectively.

The three most common subtypes in Kuwaiti Arabs were diffuse large B-cell lymphoma (46.5%), follicular lymphoma (15.5%), and mycosis fungoides (9.3%).

In non-Kuwaiti Arabs, the most common subtypes were diffuse large B-cell lymphoma (48%), B-cell small lymphocytic lymphoma/chronic lymphocytic leukemia (15.8%), and follicular lymphoma (12.7%).

Compared to the Western world, Kuwait had a lower prevalence of follicular lymphoma, a higher prevalence of diffuse large B-cell lymphoma and extranodal presentation, and a high frequency of mycosis fungoides.

Compared to other parts of Asia, Kuwait had a lower frequency of peripheral T-cell lymphomas.

[Title] Synchronous interdigitating dendritic cell sarcoma and B-cell small lymphocytic lymphoma in a lymph node.

A diagnosis of an interdigitating dendritic cell tumor of the lymph node and a B-cell small lymphocytic lymphoma occurring in the same anatomic location was made.

We found that although rare cases of interdigitating dendritic cell tumor with an associated secondary malignancy have been described in the literature, to our knowledge, this is the first report of interdigitating dendritic cell tumor and synchronous neoplasm diagnosed at the same site.

Ongoing phase 1 studies of ABT-263 show anti-tumor activity in CLL and some lymphomas (Wilson W et al, ASH. 2008).

We tested 2 strategies to mitigate variability in circulating platelet levels and achieve higher cumulative exposure: introducing a lower lead-in dose and using a continuous dosing (CD) (21/21 d schedule).

For pts receiving 150 mg lead-in, nadir occurred during this phase, and platelet levels remained relatively stable on CD for doses up to 225 mg.

While CD enrollment and time on study is still limited, anti-tumor activity includes 1 unconfirmed partial response (68% CT regression) in a SLL pt at 275 mg and 3 CLL pts with ≥50% lymphocyte reduction for ≥2 months.

[Title] ABT-263 activity and safety in patients with relapsed or refractory lymphoid malignancies in particular chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL).

ABT-263 displays activity (EC₅₀ ≤ 1μM) against human lymphoid and small cell lung cancer cell lines.

Mechanism based preclinical toxicities include reductions in circulating lymphocytes, apoptosis of circulating platelets, and decreased spermatogenesis, mediated by inhibition of Bcl-2, Bcl-X_L, and Bcl-w, respectively.

Among 27 CLL/SLL pts, 3 have confirmed radiographic partial responses (PR) (99%, 92% and 72%) and 2 have unconfirmed regressions, 51% and 72%.

6 pts maintained a ≥50% decrease in circulating lymphocytes for ≥ 2 months and 11 pts have stable disease; of these 5 experienced minor radiographic responses (range of 36% to 49%).

In addition, among 40 (M06-814) lymphoma pts, 3 with follicular lymphoma achieved PR and one had a minor response (49% regression).

With CD dosing (16 pts), activity includes 1 unconfirmed PR in SLL & and 3 CLL pts with ≥50% lymphocyte reduction for ≥2 months duration.

CONCLUSIONS: ABT-263 showed favorable PK and safety profiles with anti-tumor activity in relapsed/refractory CLL/SLL and follicular lymphoma.

[Title] VSV Oncolysis in Combination With the BCL-2 Inhibitor Obatoclax Overcomes Apoptosis Resistance in Chronic Lymphocytic Leukemia.

In chronic lymphocytic leukemia (CLL), overexpression of antiapoptotic B-cell leukemia/lymphoma 2 (BCL-2) family members contributes to leukemogenesis by interfering with apoptosis; BCL-2 expression also impairs vesicular stomatitis virus (VSV)-mediated oncolysis of primary CLL cells.

In the effort to reverse resistance to VSV-mediated oncolysis, we combined VSV with obatoclax (GX15-070)'a small-molecule BCL-2 inhibitor currently in phase 2 clinical trials'and examined the molecular mechanisms governing the in vitro and in vivo antitumor efficiency of combining the two agents.

In combination with VSV, obatoclax synergistically induced cell death in primary CLL samples and reduced tumor growth in severe combined immunodeficient (SCID) mice-bearing A20 lymphoma tumors.

Combination treatment triggered the release of BAX from BCL-2 and myeloid cell leukemia-1 (MCL-1) from BAK, whereas VSV infection induced NOXA expression and increased the formation of a novel BAX-NOXA heterodimer.

These studies offer insight into the synergy between small-molecule BCL-2 inhibitors such as obatoclax and VSV as a combination strategy to overcome apoptosis resistance in CLL.

[Title] [Bilateral tonsillar hypertrophy as the first manifestation of B cell-small lymphocytic lymphoma with interfolicular pattern].

[Transliterated title] Hipertrofia amigdalina bilateral como primera manifestación de linfoma de linfocitos pequeños B con patrón interfolicular.

B-cell small lymphocytic lymphoma typically involves nodal or extranodal tissues as a diffuse proliferation with proliferation centers (pseudofollicules) obliterating normal architecture.

But there are unusual patterns of involvement including interfollicular pattern that can be difficult to recognize histologically and probably represent partial or early involvement by neoplasm.

Tonsillar lymphoma usually presents either as a unilaterally enlarged palatine tonsil or as an ulcerative and fungating lesion over the tonsillar area.

Most lymphomas that involve the tonsil are diffuse large B cell lymphomas and primary low-grade lymphomas are exceptional.

We present a primary B-cell small lymphocytic lymphoma affecting palatine tonsils with interfollicular pattern in a 54 year-old man that clinically presented with symmetric / bilateral tonsillar enlargement and sleep apnea.

[Title] A phase I trial of TRU-016, an anti-CD37 small modular immunopharmaceutical (SMIP) in relapsed and refractory CLL.

Pre-clinical studies have demonstrated CD37 SMIP mediates significantly greater direct and NK-cell mediated killing of CLL cells as compared to other therapeutic antibodies used in CLL.

METHODS: Patients with relapsed/refractory CLL or SLL who had adequate organ function, platelets > 30,000/mm³ were eligible.

Dose escalation and de-escalation is based on CTC AE toxicity grades.

Two patients had partial clearing of leukemia cutis, and the other six had 27-94% reduction in peripheral lymphocyte count.

One pt. had an increase in Hgb of 40% and a reduction in lymph nodes of 36%.

CONCLUSIONS: To date, TRU-016 is a well tolerated treatment with minimal infusional toxicity and no observed dose limiting toxicity.

Encouraging reduction in tumor lymphocyte blood counts, lymph node/spleen size and improvement in normal hematopoeitic function in patients with high risk genomic CLL have already been observed at low, non-saturating doses of CD37.

[Title] Chronic lymphocytic leukemia (CLL) coexistent with HIV: An increasing association?

METHODS: Cases of HIV-associated CLL/small lymphocytic leukemia (SLL) were collected from the authors' archives and published case reports (using PubMed search).

Information regarding patient demographics (age, gender), mode of HIV acquisition, HAART use, immunosuppression (HIV Viral load [VL], CD4+ cell count), clinical presentation, pathology, and outcome were abstracted and analyzed.

CLL/SLL was diagnosed by lymph node biopsy (n = 1) and/or flow cytometry (n = 5).

Two patients remained well without treatment and 4 required therapy due to either hemolytic anemia, CLL- induced renal failure, pancytopenia, or hypogammaglobulinemia with recurrent infections.

CONCLUSIONS: CLL/SLL may occur in association with HIV infection in the elderly without significant concomitant immunosuppression.

CLL-related complications in our small series were frequent (67%), including mortality (50%).

Additional cases of CLL/SLL are anticipated as HIV-infected patients in the HAART era are reported to be living longer.

Chromosome 6q deletions are also commonly found in lymphoid malignancies such as acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), non-Hodgkins lymphoma (NHL), multiple myeloma (MM), mantle zone lymphoma (MZL), and Waldenström's macroglobulinemia (WM).

In childhood B- and T-cell ALL a deletion of 6q is the hallmark of a neutral prognosis; however, it may be cytogenetically obscure or cryptic, requiring interphase FISH analysis.

In adult ALL it indicates a favorable prognosis, but in CLL, B-cell small lymphocytic lymphoma (SLL), WM, and MM it has a poor prognosis.

[Title] Chronic lymphocytic leukaemia and small lymphocytic lymphoma: overview of the descriptive epidemiology.

The 2001 World Health Organization classification scheme considers B-cell chronic lymphocytic leukaemia (CLL) and small lymphocytic lymphoma (SLL) in an aggregate category (CLL/SLL) because of shared clinicopathological features.

We have estimated age-adjusted incidence rates (IRs) of CLL and SLL in the population-based Surveillance, Epidemiology and End Results Program in the United States to analyse patterns of CLL and SLL separately and jointly.

Age-standardized to the 2000 US population, overall IRs were 3.83 per 100 000 person-years for CLL (n = 15 676) and 1.31 for SLL (n = 5382) during 1993-2004.

Incidence of the combined entity, CLL/SLL, was 90% higher among males compared to females, and the male:female IR ratio was significantly higher for CLL (1.98) than for SLL (1.67).

CLL/SLL IRs were 25% and 77% lower among Blacks and Asian/Pacific Islanders, respectively, compared to Whites.

A significant reporting delay was evident for CLL but not for SLL, so that CLL/SLL temporal trends must be interpreted cautiously.

CLL and SLL IRs increased exponentially with age among all gender/race groups, with CLL IRs increasing more steeply with advancing age than SLL.

[Title] Fine-needle aspiration biopsy findings in patients with small lymphocytic lymphoma transformed to hodgkin lymphoma.

Although small lymphocytic lymphoma (SLL) is an indolent lymphoma, approximately 5% of cases can transform to a higher-grade lymphoma, rarely Hodgkin lymphoma (HL).

We report the fine-needle aspiration (FNA) results of 6 cases of SLL/chronic lymphocytic leukemia (CLL) that transformed to HL.

The patients included 5 men and 1 woman, ranging in age from 49 to 72 years at the time of SLL/CLL diagnosis with time for development of HL ranging from 0 to 95 months (mean, 49.3 months).

The FNA diagnoses were SLL with HL transformation (2 cases), SLL with large atypical cells (1 case), and atypical lymphoid proliferation with large atypical cells (3 cases).

Flow cytometry performed in 5 cases (2 FNA specimens) demonstrated a monoclonal B-cell population with CD19/CD5 coexpression.

The presence of large atypical mononucleated and binucleated cells in lymph node FNA specimens from patients with SLL/CLL with progressive adenopathy should raise the possibility of transformation to HL.

[Title] Primary manifestation of small lymphocytic lymphoma in the prostate.

BACKGROUND: Infiltration of non-haematopoietic organs by small lymphocytic lymphoma/chronic lymphocytic leukaemia (SLL/CLL) is not unusual in late-stage disease and thus quite frequently encountered in post-mortem examinations.

However, primary manifestation of SLL/CLL in the prostate is rarely diagnosed.

PATIENTS AND METHODS: We report two cases of primary prostatic SLL/CLL, in one case in combination with prostate carcinoma, and discuss diagnostic pitfalls, pathophysiological mechanisms and therapeutic management, together with an overview of the literature.

CONCLUSIONS: Lymphocytic infiltration of the prostate associated with obstructive symptoms is rare but can already occur in very early disease.

Microscopically, SLL/CLL infiltration can be distinguished from chronic prostatitis by its pattern of infiltration and by immunohistochemistry.

As the incidence of both SLL/CLL and prostatic carcinoma increases with age, composite tumours might occur more often in the future.

[Title] Community-based phase II trial of pentostatin, cyclophosphamide, and rituximab (PCR) biochemotherapy in chronic lymphocytic leukemia and small lymphocytic lymphoma.

We conducted a multicenter, community-based phase II trial of PCR biochemotherapy (pentostatin 4 mg/m2, cyclophosphamide 600 mg/m2, and rituximab 375 mg/m2) every 3 weeks for up to 6 cycles in patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).

PCR is active in CLL/SLL, but appears to be less active and associated with more complications in the community setting, compared to trials with younger, lower risk patients who travel to academic referral centers for treatment.

[Title] Cervical cancer coexisting with small lymphocytic lymphoma detected during positron emission tomography/computed tomography simulation: a case report.

CASE: A 63-year-old woman who was deemed inoperable due to carcinoma of the cervical stump extending to the parametria and paraaortic lymph nodes detected on MR images presented for extended field radiotherapy.

The excisional biopsy was consistent with small lymphocytic lymphoma (SLL).

CONCLUSION: In our case, PET/CT simulation not only led to changes in treatment management, but also revealed a very rare coexistence of SLL and invasive squamous cell carcinoma of the cervix.

[Title] Expression of the human concentrative nucleotide transporter 1 (hCNT1) gene correlates with clinical response in patients affected by Waldenström's Macroglobulinemia (WM) and small lymphocytic lymphoma (SLL) undergoing a combination treatment with 2-chloro-2'-deoxyadenosine (2-CdA) and Rituximab.

In vitro studies of resistant human cell lines have confirmed that human concentrative nucleoside transporter 1 (hCNT1)-deficient cells display resistance.

EXPERIMENTAL DESIGN: We applied real-time PCR method to assess the mRNA expression of equilibrative and concentrative nucleoside transporter (hENT1, hCNT1), deoxycytidine and deoxyguanosine kinase (dCK, dGK), 5'-nucleotidase (5'-NT), ribonucleotide reductase catalytic and regulatory (RR1, RR2) subunits in bone marrow cells from 32 patients with Waldenström's Macroglobulinemia (WM) and small lymphocytic lymphoma (SLL) who received 2CdA-based chemotherapy.

RESULTS: All 32 patients enrolled expressed lower levels of hCNT1 as compared to healthy donors.

In univariate analysis, lower expression level of hCNT1 (p=0.0021) and RR2 (p=0.02) correlated with response to chemotherapy.

In particular, patients with low levels of hCNT1 achieved inferior clinical response.

This study suggests that nucleotidase expression levels can be used to identify subgroups of WM and SLL patients who will likely respond differently to a 2CdA-based therapy.

[Title] Small lymphocytic lymphoma involving an enlarging complex renal cyst.

Cervical lymph node biopsy had revealed small lymphocytic lymphoma.

Computed tomographic scan disclosed diffuse mesenteric and retroperitoneal adenopathy consistent with chronic lymphocytic leukemia, as well as a 4.5-cm complex cystic right renal mass, which 17 months later enlarged to 6.2 cm.

Partial nephrectomy revealed infiltration of the cyst wall by small lymphocytic lymphoma.

To our knowledge, this is the first reported case of lymphoma arising in or colonizing a renal cyst.

[Title] Assessment of chronic lymphocytic leukemia and small lymphocytic lymphoma by absolute lymphocyte counts in 2,126 patients: 20 years of experience at the University of Texas M.D. Anderson Cancer Center.

PURPOSE: Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are currently considered the same entity, but controversy remains over whether CLL and SLL should be treated similarly.

We assessed whether characteristics of patients with CLL and SLL differ in ways other than the absolute lymphocyte count (ALC) and evaluated treatment outcomes and prognostic factors.

METHODS: We searched the electronic database for patients with CLL or SLL who presented to The University of Texas M.D.

RESULTS: Among 2,126 consecutive CLL/SLL patients, 312 (15%) had ALC less than 5 x 10(9)/L.

CONCLUSION: Patients with CLL or SLL can be treated similarly.

[Title] Combination therapy with fludarabine and rituximab followed by alemtuzumab in the first-line treatment of patients with chronic lymphocytic leukemia or small lymphocytic lymphoma: a phase 2 trial of the Minnie Pearl Cancer Research Network.

BACKGROUND: The purpose of the current study was to evaluate the efficacy and toxicity of the combination of fludarabine and rituximab, followed by alemtuzumab, as first-line treatment for patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).

METHODS: In a nonrandomized phase 2 trial, 41 patients who had previously untreated CLL or SLL and required treatment received 4 cycles of the fludarabine and rituximab combination followed 5 weeks later by 4 weeks (12 doses) of intravenous alemtuzumab therapy.

RESULTS: Initial treatment with the combination of fludarabine and rituximab was well tolerated, and produced a 71% overall response rate (13% complete response).

[Title] [Well-differentiated lymphocytic lymphoma of the prostate. Case report and bibliographic review].

[Transliterated title] Linfoma linfocítico, bien diferenciado de la próstata, presentación de un caso y breve revisión de la literatura.

OBJECTIVE: To report a case of prostate lymphoma and a brief review of the literature.

Surgery with retropubic prostatectomy was performed, and pathology revealed a primary prostate lymphoma.

The case study is followed by a brief bibliographic review, where we analyse clinical menifestations of this entity, complementary studies useful for diagnosis (laboratory test, trasrectal prostate biopsy, transuretral resection, ultrasound and computerised axial tomography), treatment options (surgery, polychemotherapy, radiotherapy) as well as survival in these patients.

CONCLUSIONS: Of the cases reviewed, mean age at diagnosis was 57 years.

Clinical debut was with prostate symptoms, with or without AUR and sometimes manifestations of renal failure due to obstructive uropathy, as well as general symptoms (astenia, anorexia, weight loss).

PSA values remain unaltered in prostate lymphoma patients.

Histologic diagnosis may be made by transrectal prostate biopsy, although transurethral resection (TUR) may be necessary for confirmation.

Ultrasound and CT scan are of great utility for diagnosis of both local and distant tumors.

From a therapeutic point of view, surgery for the obstruction of the lower urinary tract (TURP or retropubic prostatectomy) may be necessary, as well as the cyclophosphamide based polychemotherapy with corticosteroids and other cytostatic agents, and radiotherapy; intratecal chemotherapy has also been used adjuvant bone marrow transplantation.

[Title] Autoimmune pancreatitis and concurrent small lymphocytic lymphoma: not just a coincidence?

Computed tomography imaging revealed fullness of the pancreatic head and multiple enlarged retroperitoneal lymph nodes.

Several enlarged lymph nodes in the aortocaval region and a firm hard mass in the pancreatic head were found.

Frozen section from one of the lymph nodes was suspicious for low-grade lymphoma.

The retroperitoneal lymph nodes were involved by small lymphocytic lymphoma.

DISCUSSION: Autoimmune pancreatitis is the most common benign diagnosis after pancreatic resection for presumed malignancy.

It has a well-documented association with autoimmune conditions, such as Sjögren's syndrome, inflammatory bowel disease, and sclerosing cholangitis.

Additionally, chronic lymphocytic leukemia-small lymphocytic lymphoma is often associated with autoimmune phenomena, most notably autoimmune hemolytic anemia.

However, an association between autoimmune pancreatitis and small lymphocytic lymphoma has not been previously described.

To our knowledge, this is the first reported case of a patient with concurrent autoimmune pancreatitis and small lymphocytic lymphoma.

[Title] Indolent systemic mastocytosis associated with atypical small lymphocytic lymphoma: a rare form of concomitant lymphoproliferative disease.

Patients with systemic mastocytosis (SM) may acquire an associated hematologic non-mast cell (MC)-lineage disease (AHNMD).

In most cases, a myeloid neoplasm is diagnosed, whereas the occurrence of a lymphoproliferative disease is an extremely rare event.

We report on a patient with indolent SM associated with small lymphocytic lymphoma (SLL).

The patient presented with lymphadenopathy, maculopapular exanthema, and elevated serum tryptase.

The bone marrow biopsy showed focal MC aggregates together with SLL.

As assessed by immunostaining, neoplastic MC were found to exhibit CD117 and CD25 but did not display CD5 or CD20, whereas SLL cells were found to coexpress CD5 and CD20 but did not express MC antigens.

The KIT mutation D816V was detected in sorted CD34(+) cells and unfractionated marrow cells but not in CD5(+) SLL cells, confirming the coexistence of 2 distinct neoplasms.

[Title] A phase I/II study of rituximab and etanercept in patients with chronic lymphocytic leukemia and small lymphocytic lymphoma.

Rituximab has modest activity in relapsed chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma but is associated with tumor necrosis factor-alpha (TNF-alpha) release that can cause CLL proliferation and inhibit apoptosis.

The combination of etanercept and thrice weekly rituximab produces durable remissions in non-del(17p13.1) CLL patients and is well tolerated.

[Title] Fine-needle aspiration diagnosis of squamous cell carcinoma in a lymph node involved with small lymphocytic lymphoma: case report and review of the literature.

Diagnosis of two distinct malignant entities existing concurrently and at the same location (synchronous malignancy) by fine- needle aspiration (FNA) is unusual but may occur.

Small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) in particular is associated with an increased incidence of secondary tumor, likely due to associated immunodeficiency.

Co-occurrence of some carcinomas such as squamous cell carcinoma (SCC), may show especially aggressive behavior.

A 57-year-old Caucasian male presented with recurrent upper extremity lymphedema and diffuse lymphadenopathy of the axillary and cervical regions.

FNA of a large cervical lymph node was diagnostic for both atypical lymphocytic proliferation and SCC.

Flow cytometric analysis showed the atypical lymphocytic proliferation to be positive for CD5, CD23, CD19, CD20, HLA-DR, CD38, and the population was kappa light chain restricted.

These cells were negative for CD-10 and FMC-7 antigens, suggesting a phenotype of B-cell SLL/CLL.

We report a rare occurrence of metastatic SCC to a lymph node infiltrated by SLL/CLL.

The diagnosis was achieved by a combination of cytomorphologic examination of FNA smears, immunohistochemical staining of cell block material, and flow cytometry on the sample obtained by FNA.

To the best of our knowledge, only three cases of SCC metastasis to SLL/CLL diagnosed by FNA have been reported in the English literature.

[Title] AID protein expression in chronic lymphocytic leukemia/small lymphocytic lymphoma is associated with poor prognosis and complex genetic alterations.

The biological behavior of chronic lymphocytic leukemia and small lymphocytic lymphoma is unpredictable.

Nonetheless, non-mutated IgV(H) gene rearrangement, ATM (11q22-23) and p53 (17p13) deletion are recognized as unfavorable prognosticators in chronic lymphocytic leukemia.

The mRNA expression of activation-induced cytidine deaminase (AID), an enzyme indispensable for somatic hypermutation processes, was claimed to be predictive of non-mutated chronic lymphocytic leukemia cells in blood.

Here, we evaluated AID protein expression compared with known molecular and immunohistochemical prognostic indicators in 71 chronic lymphocytic leukemia/small lymphocytic lymphoma patients using a tissue microarray approach.

Twenty-five percent (17/69) of patients with AID-positive chronic lymphocytic leukemia/small lymphocytic lymphoma displayed a shorter survival than AID-negative chronic lymphocytic leukemia/small lymphocytic lymphoma patients (61 vs 130 months, P=0.001).

Taken together, our study shows that AID expression is an indicator of an unfavorable prognosis in chronic lymphocytic leukemia/small lymphocytic lymphoma patients, although it is not a surrogate marker for the IgV(H) status.

[Title] Composite small lymphocytic lymphoma and extra-medullary myeloid tumor: a potential diagnostic pitfall.

Reported herein is a case of composite small lymphocytic lymphoma (SLL) and extramedullary myeloid tumor (EMT) occurring in the same lymph node.

Routine morphologic examination revealed a diffuse proliferation of small mature lymphocytes with numerous irregularly dispersed nodules, closely resembling SLL with prominent proliferation centers or Richter's transformation.

Flow cytometric immunophenotyping and immunohistochemical stains demonstrated the presence of SLL cells as well as myeloblasts, confirming the diagnosis of a composite SLL and EMT.

In conclusion, the occurrence of SLL and EMT in the same lymph node is rare and multiparameter approach is essential for a definitive diagnosis.

[Title] Synchronously diagnosed lymph nodal collision tumor of malignant melanoma and chronic lymphocytic leukemia/small lymphocytic lymphoma: case report.

We report a case of chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma and malignant melanoma (MM) occurring synchronously in the same lymph node.

To our knowledge this is the first time that synchronous occurrence of these two malignant processes in the same tissue is described.

In this case it is important that the melanoma was recognized in the excised lymph node, as this finding had much more critical treatment and long term survival consequences.

[Title] Systemic mastocytosis associated with small lymphocytic lymphoma: an incidental finding in a patient with invasive gastric adenocarcinoma.

We report an interesting case of systemic mastocytosis diagnosed incidentally in an omental lymph node in the setting of an invasive gastric adenocarcinoma.

The Diff-Quick touch preparation of the lymph node revealed abundant single cells and loose aggregates of cells with round to oval nuclei and deeply basophilic granules.

Monotonous proliferation of small mature lymphocytes and many eosinophils were also present in the background.

The frozen section and permanent sections of lymph node showed partial to complete replacement of lymph node by neoplastic mast cells.

[Title] Increased trisomy 12 frequency and a biased IgVH 3-21 gene usage characterize small lymphocytic lymphoma.

Small lymphocytic lymphoma (SLL) and chronic lymphocytic leukemia (CLL) are considered as similar entity by the WHO classification.

We assessed the distribution of the four prognostic cytogenetic markers (deletion 11q23, 13q14, 17p13 and trisomy 12) and VH mutational status in 32 SLL and 119 CLL.

Trisomy 12 was most frequent (36% vs 13%, p=0.014) and 13q14 deletion was less frequent (9% vs 44%, p=0.001) in SLL in comparison with CLL.

An over representation of VH3-21 gene usage was found in SLL (17% vs 1%, p=0.011).

In conclusion, SLL show specific genetic markers that distinguish them from classical CLL.

[Title] Diagnosis and prognosis of B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (B-CLL/SLL) and mantle cell lymphoma (MCL).

BACKGROUND: B-cell chronic lymphocytic leukemia/ small lymphocytic lymphoma (B-CLL/SLL) and mantle cell lymphoma (MCL) show many overlapping morphologic and immunophenotyping features, however they have great difference in therapeutic regimens and prognosis.

THE AIM OF THE STUDY: Is to determine the diagnostic and prognostic role of clinico-pathologic variables, CD23 and Cyclin D1 oncoprotiens in B-SLL/CLL and MCL.

PATIENTS AND METHODS: This study included 25 BCLL/ SLL cases and 25 MCL cases.

RESULTS: There was significant difference between BCLL/ SLL and MCL regarding several items including pattern of growth, where interfollicular pattern was restricted to B-SLL/CLL while nodular and mantle zone pattern were confined to MCL; pseudo-follicles were only present in B-CLL/SLL.

Transformed cells, plasmacytoid cells, peripheral blood lymphocytosis, significant longer survival and good prognosis were statistically more prominent in favor of B-CLL/SLL.

On the other hand, cell cleavage, epithelioid histiocytes, plasma cells, naked nuclei, hyalinized venules, deposited hyaline material in background and reticular fibers in addition to higher mitotic index per 20 HPF were more significantly identified in favor of MCL.

CD23 was expressed as membranous pattern in 16/25 (64%) of B-CLL/SLL cases and 1/25 (4%) of MCL cases.

On the other hand, Cyclin D1 was expressed as nuclear staining in 18/25 (72%) of MCL cases and only 1/25 (4%) of B-CLL/SLL cases.

Regarding B-CLL/SLL, age >60 years and mitosis >or=10/20 HPF were independent prognostic factors of shorter survival by multivariate analysis.

CONCLUSION: Cyclin D1 is not only implicated in tumor genesis of MCL, but also in progression and extension of the disease when expressed in high levels (50% cut off value) and it seems to have prognostic impact in MCL.

This can be used as a basis for future therapeutic strategies targeting cell cycle regulators.

This study could support the concept that Cyclin D1 and CD23 immunostaining may be reliable diagnostic tools for discrimination between B-CLL/SLL and MCL.

[Title] The spectrum of coincident entities with small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) diagnosed by cytology.

BACKGROUND: The cytologic diagnosis of Small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) often relies on finding a small lymphoid population with the characteristic immunoprofile by ancillary testing.

There are only a few reports of other processes identified with SLL/CLL.

The aim of this study was to review the fine needle aspiration (FNA) and touch prep (TP) diagnoses of SLL/CLL in order to identify any coincident entities.

MATERIALS AND METHODS: We retrospectively reviewed all FNA and TP cytology cases between January 2005 and May 2009 with a diagnosis of SLL/CLL to determine the presence of any coincident process.

Coincident entities were identified in nine cases (31%) and included seven (28%) neoplastic entities (Hodgkin lymphoma [HL], adenocarcinoma, squamous cell carcinoma, seminoma) and two (7%) non-neoplastic entities (infection and immunoglobulin containing cells).

Six cases (21%) suspicious for large cell transformation were also identified.

CONCLUSION: In our review of SLL/CLL, coincident entities were present in 31% of the cases and included a spectrum of non-neoplastic and neoplastic processes.

FC was the most frequently utilized ancillary test, but IHC provided important information by excluding a mantle cell lymphoma or confirming a coincident process.

[Title] Autoimmune cytopenia in chronic lymphocytic leukemia/small lymphocytic lymphoma: changes in clinical presentation and prognosis.

Improved medical care could have altered the clinical presentation and survival of patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) complicated by autoimmune disease cytopenia (AID cytopenia).

When compared with the historical reported data, our study shows a lower rate of autoimmune hemolytic anemia (2.3%), and similar rates of immune thrombocytopenia (2.0%), and pure red blood cell aplasia (0.5%).

AID cytopenia occurred at all stages of CLL, responded well to treatment, did not alter overall survival, and contributed to death in only 6 (12%) patients.

[Title] The proliferation center microenvironment and prognostic markers in chronic lymphocytic leukemia/small lymphocytic lymphoma.

Prognostication in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) based, in part, on ZAP-70 and CD38 expression, and to a lesser extent, on MUM1/IRF4 expression, is currently of great interest.

The more aggressive type of CLL/SLL is reportedly characterized by neoplastic cells that are more responsive to B-cell signaling with proliferation centers (PCs), a potentially important site of neoplastic cell stimulation.

To study the relationship of these markers to each other and to the pattern of PCs, immunohistochemical stains for ZAP-70 and MUM1/IRF4 were performed and the PC patterns assessed (where possible) in 29 tissue biopsies with CLL/SLL.

Seven cases, none with atypical PC, also showed uniform positivity throughout, 14 showed weaker staining of surrounding lymphocytes, and 8 had PC staining only.

These findings highlight the complex interrelationship of prognostic markers in CLL/SLL and demonstrate potentially important microenvironmental variations in their expression.

They support the hypothesis that PCs are a site for B-cell receptor signaling, which helps explain reported site-dependent antigenic variation in CLL/SLL, and suggest that PC morphology may correlate with other biological features.

[Title] Chronic lymphocytic leukemia/small lymphocytic lymphoma associated with IgM paraprotein.

We studied the clinicopathologic, immunophenotypic, and cytogenetic features of 26 patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) associated with serum IgM paraprotein.

The study group (16 men; 10 women; median age, 64 years; range, 40-82 years) represents approximately 2.5% of CLL/SLL cases at our institution.

The paraprotein level ranged from 1 to 14 g/L (median, 4 g/L).

Neoplasms in bone marrow were composed of small round lymphocytes arranged in nodular (n = 6), diffuse (n = 5), interstitial (n = 5), or mixed (n = 10) patterns.

The overall survival of this group (median follow-up, 24 months) was not significantly different from that for an age-, sex-and stage-matched group of 52 CLL/SLL patients without IgM paraprotein (P = .60).

We conclude that CLL/SLL cases with serum IgM paraprotein are similar to other CLL/SLL cases in their clinicopathologic and immunophenotypic features.

[Title] Characterization of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) in Shanghai, China: molecular and cytogenetic characteristics, IgV gene restriction and hypermutation patterns.

The clinical, cytogenetic and molecular features of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), a disease previously considered to be rare in Asia, were examined in consecutive series of 70 cases diagnosed by our laboratory over a 30-month period.

Clonal abnormalities were observed in 80% of CLL/SLL cases using a combination of conventional cytogenetic and fluorescence in situ hybridization (FISH) analysis.

IgV(H) gene mutation status was a significant predictor of initial survival in CLL/SLL.

[Title] Renal cell carcinoma with non-Hodgkin's lymphoma infiltration: a case report.

The coexistence of renal cell carcinoma and non-Hodgkin's lymphoma is more common than expected in the general population; however, renal cell carcinoma with infiltration by non-Hodgkin's lymphoma has rarely been reported.

Here we report on a 77-year-old patient who presented with small lymphocytic lymphoma in the jugulodigastric lymph node.

On histopathological examination, the mass was diagnosed as a grade III renal cell carcinoma with infiltrated small lymphocytic lymphoma that was positive for B-cells (CD20).

[Title] Transformation of chronic lymphocytic leukemia/small lymphocytic lymphoma to interdigitating dendritic cell sarcoma: evidence for transdifferentiation of the lymphoma clone.

Interdigitating dendritic cell sarcoma (IDCS) is a rare tumor derived from interdigitating dendritic cells.

Three cases of IDCS associated with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) have been described, but no clonal relationship between the 2 neoplasms was demonstrated.

We present a detailed case analysis of a CLL/SLL with metachronous IDCS and demonstrate that these 2 neoplasms are clonally related.

Our study demonstrates for the first time clonal transformation of CLL/SLL into IDCS.

[Title] A rare case of chronic lymphocytic leukemia/small lymphocytic lymphoma presenting in the thyroid gland.

BACKGROUND: Lymphoma involving the thyroid gland is rare.

Diffuse large B-cell lymphoma and mucosa-associated lymphoid tissue lymphoma are the two most common histologic subtypes of primary thyroid lymphoma.

Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) presenting initially as a thyroid abnormality is extremely rare, with very few reported cases in the literature.

The sonographic finding of a distinct thyroid nodule in the heterogeneous background of chronic lymphocytic thyroiditis led to the performance of a fine-needle aspiration biopsy and flow cytometry, with a high index of suspicion for thyroid lymphoma.

Subsequent surgical removal of the thyroid gland, prompted by the patient's history of head and neck radiation, confirmed the diagnosis of CLL/SLL.

Although thyroiditis has long been associated with lymphoma arising in the thyroid gland, CLL/SLL involving the thyroid has not been linked to chronic lymphocytic thyroiditis.

CONCLUSIONS: Due to the rarity of thyroid lymphomas, our experience in the detection and management of this disease is limited.

Primary thyroid lymphoma should be suspected in a patient with a history of chronic lymphocytic thyroiditis presenting with a rapidly enlarging neck mass.

The initial diagnostic method for thyroid lymphoma should consist of a fine-needle aspiration biopsy with the use of ancillary techniques such as flow cytometry and immunohistochemistry for improved diagnostic accuracy.

Although controversial, the treatment of thyroid lymphoma is typically guided by the histologic subtype and extent of disease.

CLL/SLL is one of the rarest subtypes of lymphoma that can involve the thyroid gland.

Diagnosis of this entity is difficult, particularly before the recognition of systemic involvement, requiring the expertise of a multidisciplinary team for early detection and optimal management.

[Title] The treatment of recurrent/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL) with everolimus results in clinical responses and mobilization of CLL cells into the circulation.

BACKGROUND: Patients with recurrent/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL) often have chemotherapy-resistant disease, resulting in poor prognosis.

An unanticipated finding in this study was an increase in absolute lymphocyte count (ALC) associated with a decrease in lymphadenopathy in 8 (36%) patients.

CONCLUSIONS: Everolimus has modest antitumor activity against CLL and can mobilize malignant cells from nodal masses into the peripheral circulation in a subset of CLL patients.

[Title] Cytogenetic abnormalities detected by fluorescence in situ hybridization on paraffin-embedded chronic lymphocytic leukemia/small lymphocytic lymphoma lymphoid tissue biopsy specimens.

Cytogenetic fluorescence in situ hybridization (FISH) panels are a major prognostic tool in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), but few data exist on using paraffin-embedded extramedullary tissue biopsy specimens for these purposes.

Isolated whole nuclei were extracted from 20 paraffin-embedded tissue biopsy specimens with CLL/SLL and analyzed using a standard CLL FISH panel.

Cytogenetic FISH studies using paraffin-embedded tissue biopsy specimens in CLL/SLL had a high yield and, with 1 exception, demonstrated a profile similar to cases diagnosed in PB/BM.

[Title] [Clinical significance of ZAP-70 protein expression in chronic lymphocytic leukemia/small lymphocytic lymphoma].

OBJECTIVE: To study the clinicopathologic features and prognostic significance of ZAP-70 protein expression in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL).

METHODS: The histologic features of 52 cases of CLL/SLL with lymph node and/or bone marrow biopsies performed were retrospectively reviewed.

RESULTS: The lymph nodes of the 12 cases studied showed effacement of the nodal architecture and was replaced by a monotonous infiltration of small lymphoid cells.

Similar morphologic pattern was seen in the 40 bone marrow biopsy samples, but no proliferation center formation obtained.

The infiltration pattern of tumor cells in the bone marrow were further subdivided into nodular (n = 9), interstitial (n = 3), mixed (n = 9) and diffuse types (n = 19).

There was no significant difference found on survival rates between the diffuse infiltration and non-diffuse infiltration groups (Fisher's exact test, P = 0.199).

ZAP-70 protein was mainly located in the cytoplasm and nuclei of lymphoma cells.

Among the 21 dead cases, 15 died of CLL/SLL or the related infection.

CONCLUSION: A positive expression of ZAP-70 protein in CLL/SLL suggests a poor prognosis.

[Title] Most morphologic features in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) do not reliably predict underlying FISH genetics or immunoglobulin heavy chain variable region somatic mutational status.

Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is common in the Western world.

Genetic abnormalities detected by fluorescence in situ hybridization (FISH) and immunoglobulin heavy chain variable gene region (IGHV) mutational status are well-known independent prognostic indicators in CLL/SLL.

Given the requirement for specialized testing to detect such aberrations, we investigated whether morphologic features may predict the presence of a more or less favorable genetic profile.

Forty-one SLL cases were morphologically evaluated for expanded proliferation centers, increased large cells outside of proliferation centers, and nuclear contour irregularities (NCI) in small and large tumor cells.

Significant NCI in both small and large cells correlated with the presence of an unfavorable FISH abnormality (ie, ATM or p53 deletions).

No other significant associations with morphologic features were identified.

In conclusion, morphologic features in SLL are not a reliable predictor of underlying genetic status.
