  • [Title] Bevacizumab for recurrent ependymoma.
  • BACKGROUND: Ependymoma is a rare type of glioma, representing 5% of all CNS malignancies.
  • At recurrence, ependymoma is notoriously refractory to therapy and the prognosis is poor.
  • METHODS: In this Institutional Review Board-approved study, we retrospectively analyzed the records of 8 adult patients treated for recurrent ependymoma and anaplastic ependymoma with bevacizumab containing chemotherapy regimens.

  • A 15-year-old boy presented with an anaplastic supratentorial ependymoma causing massive intratumoral calcification, without contributory medical and family history, and manifesting as persistent headache for 2 months.
  • Cranial computed tomography revealed a huge calcified mass in the left parietooccipital lobe, with extensive perilesional brain edema.
  • The findings were compatible with anaplastic ependymoma (World Health Organization classification grade 3).
  • Ependymoma should be included in the differential diagnosis of a supratentorially located, extraventricular mass with massive intratumoral calcification.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Conformal radiotherapy after surgery for paediatric ependymoma: a prospective study.
  • BACKGROUND: Therapy for ependymoma includes aggressive surgical intervention and radiotherapy administered by use of methods that keep the risk of side-effects to a minimum.
  • METHODS: Between July 11, 1997, and Nov 18, 2007, 153 paediatric patients (median age 2.9 years [range 0.9-22.9 months]) with localised ependymoma were treated.
  • 85 patients had anaplastic ependymoma; the tumours of 122 were located in the infratentorial region, and 35 had received previous chemotherapy.
  • The incidence of secondary malignant brain tumour at 7 years was 2.3% (0-5.6) and brainstem necrosis 1.6% (0-4.0).
  • Overall survival was affected by tumour grade (anaplastic vs differentiated: HR 3.98 [95% CI 1.51-10.48]; p=0.0052), extent of resection (gross total vs near total or subtotal: 0.16 [0.07-0.37]; p<0.0001), and ethnic origin (non-white vs white: 3.0 [1.21-7.44]; p=0.018).
  • EFS was affected by tumour grade (anaplastic vs differentiated: 2.52 [1.2705.01]; p=0.008), extent of resection (gross total vs near total or subtotal: 0.20 [0.11-0.39]; p<0.0001]), and sex (male vs female: 2.19 [1.03-4.66]; p=0.042).
  • Distant recurrence was only affected by tumour grade (anaplastic vs differentiated: 4.1 [1.2-14.0]; p=0.017).
  • INTERPRETATION: Treatment of ependymoma should include surgery with the aim of gross-total resection and conformal, high-dose, postoperative irradiation.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Cerebrospinal fluid cytology in patients with ependymoma: a bi-institutional retrospective study.
  • BACKGROUND: Ependymoma cells are known to occasionally exfoliate into cerebrospinal fluid (CSF).
  • However, the frequency of CSF involvement in patients with ependymoma is unclear, and to the authors' knowledge the cytomorphologic features of the tumor cells have not been described in detail to date.
  • In this study, the CSF findings in patients with ependymal neoplasms are summarized and the cytomorphologic features of ependymoma, including its variants, are illustrated.
  • METHODS: A search of the pathology databases of 2 medical centers was performed to identify all patients with a histologic diagnosis of ependymoma in whom CSF samples were examined.
  • RESULTS: In all, 177 patients with a diagnosis of ependymoma were identified.
  • Of the 8 patients with positive and/or suspicious diagnoses, 5 ependymomas exhibited anaplastic features and 1 tumor was a myxopapillary ependymoma.
  • The positive samples were usually hypercellular, with cohesive epithelioid cells; long cytoplasmic processes resembling bipolar tanycytes were observed in the tanycytic variant of ependymoma.
  • CONCLUSIONS: Exfoliated cells from ependymomas are recognizable in CSF samples, especially in patients with myxopapillary tumors and tumors with anaplastic features.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Childhood intracranial ependymoma: twenty-year experience from a single institution.
  • BACKGROUND: Because few large studies of pediatric ependymoma treatment are available, the authors believed that a retrospective review of treatment outcomes from a single institution would yield potentially valuable information regarding potential prognostic factors.
  • METHODS: Medical records were reviews of patients with intracranial ependymoma who received their initial treatment at the Children's Hospital of Philadelphia (CHOP)/Hospital of the University of Pennsylvania (HUP) between January 1980 and December 2000.
  • Anaplastic histology predicted for decreased PFS.
  • CONCLUSIONS: In this study of patients with pediatric intracranial ependymoma, OS and PFS rates were concordant with the rates published in other modern series.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Intracavitary chemotherapy (Gliadel) and oral low-dose etoposide for recurrent anaplastic ependymoma.
  • Anaplastic ependymoma is associated with a higher incidence of tumor recurrence and its prognosis still remains unsatisfactory.
  • Consolidated therapy for ependymoma includes surgery followed by focal radiotherapy when resection is incomplete.
  • We sought to establish the feasibility of administering low-dose oral etoposide (50 mg/m(2)/day for 21 days) in combination with the implantation of intracavitary carmustine (BCNU) wafers (Gliadel) at the gross total resection for achieving synergistic treatment in three children affected by recurrent anaplastic ependymoma.
  • Two patients relapsed after 4 months as shown in brain MRIs.
  • This multimodal approach was not effective for the treatment of refractory anaplastic ependymoma and further studies are required in order to define the role of the combination of multidrug systemic chemotherapy with BCNU wafer implantation in children with high-risk brain tumors.

  • [Title] Bevacizumab for recurrent ependymoma.
  • : 2060 Background: Ependymoma is a rare type of glioma, representing less than 5% of brain tumors in adults.
  • At recurrence ependymoma is notoriously refractory to therapy and the prognosis is poor.
  • Therefore, we treated patients with recurrent ependymoma and anaplastic ependymoma with bevacizumab containing chemotherapy regimens.
  • METHODS: We retrospectively identified adults treated for recurrent ependymoma and anaplastic ependymoma with bevacizumab containing chemotherapy regimens.
  • CONCLUSIONS: Bevacizuamb has efficacy in the treatment of recurrent ependymoma.

  • Recurrence of clear cell ependymoma is not a rare condition, but malignant transformation of clear cell ependymoma has not yet been well presented.
  • A brain tumor in the left frontal premotor area was removed and an initial pathological diagnosis of oligodendroglioma was made.
  • The first and second surgical specimens did not contain any ependymal rosettes or pseudorosettes, and thus a diagnosis of oligodendroglioma was made.
  • At this time, the tumor had an ultrastructural appearance compatible with ependymoma.
  • Thereafter, the recurrent tumors showed anaplastic features such as nuclear pleomorphisms and necrosis with pseudopallisading.

  • [Title] Giant cell ependymoma: a case report.
  • A peculiar variant of ependymoma known as "giant cell ependymoma" ("GCE") is especially rarely reported, it may pose some difficulties for the diagnosing neuropathologist.
  • Here we present a case of a giant cell ependymoma occuring in a 17-year-old patient with the history of 2-year recurrent headaches and a 1-month history of vision impairment.
  • Histological, immunohistochemical and electron microscopic findings were consistent with high-grade ependymoma.
  • As a result the diagnosis of GCE was established.
  • This type of neoplasm necessitates, at least in theory, differentiation with anaplastic oligodendroglioma, clear cell ependymoma, pleomorphic xanthoastrocytoma, giant cell glioblastoma, and subependymal giant cell astrocytoma.

  • OBJECT: Reports on spinal cord ependymoma in children are rare.
  • The aim of this study was to evaluate the clinical spectrum, treatment, and outcome of children with primary ependymoma of the spinal cord who were registered in the database of the pediatric German brain tumor studies Hirntumor (HIT) '91 and HIT 2000.
  • METHODS: Between 1991 and 2007, 29 patients (12 male and 17 female, median age at diagnosis 13.6 years) with primary spinal cord ependymoma (myxopapillary ependymoma WHO Grade I, II, and III tumors in 6, 17, and 6 patients, respectively) were identified.
  • One patient with anaplastic ependymoma (WHO Grade III) died 65 months after diagnosis of disease progression.
  • A high relapse incidence (4 of 6) was observed among patients with myxopapillary ependymoma.
  • CONCLUSIONS: Gross-total resection is the mainstay of treatment for patients with primary spinal cord ependymoma and may be achieved in about 50% of the patients using modern surgical techniques.
  • Primary adjuvant treatment was commonly used in children with spinal cord ependymoma irrespective of the extent of resection or tumor grade.

  • The insulin-like growth factor (IGF) system plays an important role in neuronal development and may contribute to the development of brain tumors.
  • IGFBP-2 expression was indicative of poor prognosis in medulloblastomas, whereas IGFBP-3 mRNA levels were especially high in anaplastic ependymomas.
  • Protein expression levels of IGFs and IGFBPs were analyzed in the cerebrospinal fluid (CSF) of 16 medulloblastoma, 4 ependymoma and 23 control patients by radioimmuno assay to determine whether they could be used as markers for residual disease after surgery.
  • No aberrant CSF protein expression levels were found for ependymoma patients.
  • In medulloblastoma patients, the IGFBP-3 protein levels were significantly higher than in ependymoma patients and controls.

  • [Title] A case of anaplastic pleomorphic xanthoastrocytoma presenting with tumor bleeding and cerebrospinal fluid dissemination.
  • However, PXA cases having several recurrent patterns with poor prognosis have been reported in recent years, and a new concept of anaplastic PXA has been proposed.
  • Histopathological findings showed that the tumor was typical PXA with strong pleomorphism and xanthomatous changes and contained an ependymoma-like component in the center area.
  • From these findings, the histopathological diagnosis was anaplastic PXA.
  • Histopathological findings suggested anaplastic PXA from the first surgical specimens, and PXA recurred many times.
  • We thus believe that the patient displayed primary anaplastic PXA rather than secondary anaplastic PXA that results in malignant transformation.

  • [Title] Primary postoperative chemotherapy without radiotherapy for treatment of brain tumours other than ependymoma in children under 3 years: results of the first UKCCSG/SIOP CNS 9204 trial.
  • BACKGROUND: Radiotherapy is an effective adjuvant treatment for brain tumours arising in very young children, but it has the potential to damage the child's developing nervous system at a crucial time - with a resultant reduction in IQ leading to cognitive impairment, associated endocrinopathy and risk of second malignancy.
  • We aimed to assess the role of a primary chemotherapy strategy in avoiding or delaying radiotherapy in children younger than 3 years with malignant brain tumours other than ependymoma, the results of which have already been published.
  • Patients with medulloblastoma presented as a high-risk group, 83.9% having residual disease and/or metastases at diagnosis.
  • All children with large cell or anaplastic variants of medulloblastoma died within 2 years of diagnosis.
  • INTERPRETATION: The outcome for very young children with brain tumours is dictated by degree of surgical resection and histological tumour type and underlying biology as an indicator of treatment sensitivity.
  • This study highlights the differing therapeutic challenges presented by the malignant brain tumours of early childhood, the importance of surgical approaches and the need to explore individualised brain sparing approaches to the range of malignant brain tumours that present in early childhood.

  • It is very difficult to treat the patients with malignant brain tumor in children, especially under 3 years, because the conventional irradiation cannot be applied due to the damage of normal brain tissue.
  • Among 183 patients with brain tumors treated by our group using BSH-based intra-operative BNCT, 23 patients were under 15 years.
  • There were 3 glioblastomas (GBM), 6 anaplastic astrocytomas(AAS), 7 primitive neuroectodermal tumors (PNET), 6 pontine gliomas and 1 anaplastic ependymoma.
  • Four of 6 anaplastic astrocytoma and 1 anaplastic ependymoma patients alive without tumor recurrence.
  • BNCT can be applied to malignant brain tumors in children, especially under 3 years instead of conventional radiation.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Doublecortin is preferentially expressed in invasive human brain tumors.
  • These facts led us to hypothesize that DCX is increased in invasive brain tumors.
  • DCX expression was assessed in 69 paraffin-embedded brain tumors of neuroepithelial origin.
  • In addition, mouse brain sections of the subventricular zone and dentate gyrus were used as positive controls for immunostaining, and specificity of antibody staining was demonstrated by peptide neutralization.
  • DCX was highly expressed in both high-grade invasive tumors (glioblastoma, n=11; anaplastic astrocytoma/oligoastrocytoma, n=7; and medulloblastoma/PNET, n=6) and low-grade invasive tumors (oligodendroglioma, n=3; and astrocytoma/oligoastrocytoma, n=5).
  • However, DCX was less intensely expressed in the circumscribed group of tumors (pilocytic astrocytoma, n=6; ependymoma/subependymoma, n=7; dysembryoplastic neuroepithelial tumor, n=4; ganglioglioma, n=2; meningioma, n=9; and schwannoma, n=9).
  • We conclude that DCX is preferentially expressed in invasive brain tumors.
  • Collectively, the immunohistochemistry, Western blots and Northern blots conclusively demonstrate expression of DCX by human brain tumors.

  • [Title] NGAL immunohistochemical expression in brain primary and metastatic tumors.
  • Thus NGAL urinary detection has been proposed as a method for the early diagnosis of brain tumors.
  • In view of this, the objective of this study was to investigate whether NGAL expression differs according to brain tumor type or in primary vs. metastatic brain neolasias.
  • 42 surgically resected formalin fixed and paraffin embedded neoplasias, including 15 cases of brain metastasis and 27 cases of primary central nervous system (CNS) tumors (11 meningiomas; 1 pilocytic astrocytoma, 2 diffuse astrocytomas, 2 oligoastrocytomas, 2 oligodendrogliomas, 1 anaplastic oligoastrocytoma, 7 glioblastomas, 1 ependymoma) were submitted to the immunohistochemical procedure.
  • NGAL staining was found in all the analyzed glioblastomas and in the anaplastic oligoastrocytoma.
  • In conclusion, our findings suggest that NGAL expression is restricted to high grade gliomas among primary brain tumors, and that brain metastases do not express this protein.
  • Considering the correlation between NGAL expression in tumors and its urinary levels, if our observations will be further validated, NGAL urinary detection might be used as an additional tool in the pre-surgical definition of brain lesions involving difficult differential diagnosis.

  • OBJECTIVE: To detect and analysis epidermal growth factor receptor (EGFR) and phosphatase and tensin homolog deleted on chromosome ten (PTEN) in different malignancy brain tumors, and to evaluate their prognostic significance.
  • METHODS: Using immunohistochemistry to detect the expression of EGFR and PTEN and adopting confocal technology to verify their location in the specimens of 25 respectively glioblastoma multiformes, medulloblastomas, anaplastic oligodendrogliomas, and anaplastic ependymomas.
  • However amplification of EGFR and deletion of PTEN were relatively low in other malignancy brain tumors.
  • They were 36% and 8% in medulloblastomas, and 28% and 8% in anaplastic oligodendrogliomas, and 24% and 4% in anaplastic ependymomas.
  • PTEN mutation and EGFR overexpression are rare in medulloblastoma, anaplastic oligodendroglioma, and anaplastic ependymoma, so the EGFR or PTEN targeted antitumor approaches may be useful in glioblastoma multiformes but the other 3 tumors.

  • [Title] Distribution of 4-hydroxynonenal-protein conjugates as a marker of lipid peroxidation and parameter of malignancy in astrocytic and ependymal tumors of the brain.
  • It results in the production of 4-hydroxynonenal (HNE), which plays a crucial role in hypoxic brain injury, neuronal degeneration and apoptosis.
  • Significantly higher HNE expression was found in tumor cells of glioblastomas multiforme than in cells of pilocytic astrocytomas (P < 0.005), and in anaplastic ependymomas than in benign ependymomas (P < 0.01).
  • HNE was expressed in the endothelium of almost all tumor vessels, but its expression in the walls of the vessels was significantly higher in diffuse and anaplastic astrocytomas than in pilocytic astrocytomas and glioblastomas multiforme (P < 0.05).
  • Therefore, HNE might be involved in the damage of brain cells and the induction of malignancy.

  • [Title] Pediatric brain tumours at a tertiary care hospital in Karachi.
  • The objectives of this study were to determine the epidemiology of brain tumors during infancy and childhood and to define and segregate childhood brain tumors vis-a-vis their morphological characteristics.
  • The present study includes pediatric brain tumors, ICD-10 category C71 encountered during 10 years (January 1989 through December 1998) at a tertiary care hospital in Karachi.
  • The morphological distribution of cases was astrocytoma (28 cases, 34.6%), primitive neuroectodermal tumor or PNET (40 cases; 49.4%), ependymoma (8 cases, 10%), mixed glioma (4 cases; 5%) and a case of oligodendroglioma.
  • The morphological categorization of supratentorial tumors was astrocytoma (17 cases; 63%), ependymoma (5 cases; 18.5%), mixed glioma (2 cases; 7.4%).
  • The 17 supratentorial astrocytoma were sub-categorized as follows - pilocytic astrocytoma (5 cases; 29.4%), grade II astrocytoma (6 cases; 35.3%); grade III astrocytoma (2 cases; 11.8%), anaplastic astrocytoma (1 case; 5.9%) and glioblastoma multiforme (3 cases; 17.7%).
  • The morphological categorization of infratentorial tumors was astrocytoma (11 cases; 20.4%), medulloblastoma (38 cases; 70.4%), ependymoma (3 cases; 5.6%) and mixed glioma - astroependymoma (2 cases, 3.7%).
  • The morphological sub-categorization of infratentorial astrocytoma was pilocytic astrocytoma (7 cases, 63.6%), with gemistocytic astrocytoma, grade II, grade III and anaplastic astrocytoma comprising 1 (9.1%) case each.
  • The pediatric brain tumors in Karachi reflect a developing country scenario, with a strong male predisposition and a late presentation with a peak in the 5-9 year age group.
  • Population-based studies are required to determine the cancer burden due to pediatric malignancies of the brain in this population and for the morphological categorization of brain tumors in Karachi.

  • [Title] Quantitative short echo time 1H-MR spectroscopy of untreated pediatric brain tumors: preoperative diagnosis and characterization.
  • PURPOSE: Our aims were to evaluate the metabolic profiles of pediatric brain tumors with short echo time (TE) MR spectroscopy and absolute quantitation of metabolite concentrations (in mmol/kg of tissue) and to describe metabolic features that distinguish individual tumor types and that may help to improve preoperative diagnosis of specific tumors.
  • METHODS: MR imaging examinations of 60 patients with untreated brain tumors (14 medulloblastomas, 5 anaplastic astrocytomas, 3 low-grade astrocytomas, 17 pilocytic astrocytomas, 4 anaplastic ependymomas, 5 ependymomas, 3 choroid plexus papillomas, 3 choroid plexus carcinomas, and 6 pineal germinomas) were reviewed.
  • Guanidinoacetate was reduced in low-grade astrocytomas and anaplastic astrocytomas (P < .00001) versus All Other, whereas ependymoma and anaplastic ependymomas exhibited particularly low N-acetylaspartate (P < .00001 versus All Other).
  • CONCLUSION: Quantitative proton MR spectroscopy reveals features of pediatric brain tumors that are likely to improve preoperative diagnoses.

  • This retrospective study aimed to evaluate the safety and toxicity of intrathecal liposomal cytarabine (Depocyte) in children and adolescents with refractory or recurrent brain tumors.
  • Nineteen heavily pretreated patients (males, n = 14; females, n = 5; median age at diagnosis 8.5 years; range, 1.4-22 years) were given intrathecal liposomal cytarabine on a compassionate use basis for recurrent refractory medulloblastoma (n = 12), mixed germ cell tumor (n = 2), central nervous system primitive neuroectodermal tumors of the pons (n = 1), anaplastic ependymoma (n = 1), anaplastic oligodendroglioma (n = 1), atypical teratoid rhabdoid tumor (n = 1), or rhabdoid papillary meningioma (n = 1).
  • In conclusion, although intrathecal liposomal cytarabine was generally well tolerated, it should be used cautiously and only with dexamethasone prophylaxis in extensively pretreated patients with recurrent brain tumors.

  • Statistically significant difference was present for Ki-67 LI between ependymomas (grade II, WHO) and anaplastic ependymomas (grade III, WHO) (p < 0.001) (mean Ki-67 LI for ependymoma, 2.8%, for anaplastic ependymomas, 15.6%).
  • Anaplastic ependymomas did not demonstrate a greater vascularization than ependymomas, and the MVD values were 84.5 +/- 39.7 for ependymomas, and 90.6 +/- 61.4 for anaplastic ependymomas.
  • Although Cox-2 expression was slightly higher in anaplastic ependymomas, it was not statistically significant.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Ependymal tumors are classified as ependymoma (benign or low grade) versus anaplastic ependymoma (malignant or high grade).
  • Histologic subgroups were 18 ependymomas (43.6%), and 22 anaplastic ependymomas (56.4%).
  • Postoperative treatment consisted of regional (8 patients) or craniospinal (CSI) (9 patients) radiotherapy (RT) in patients with ependymoma; regional (7 patients) or CSI RT (14 patients) with chemotherapy (ChT) in patients with anaplastic ependymoma; ChT only (1 patient) in patients less than 3 years of age.
  • The median age at diagnosis is 6 years in our patient group; younger children (less than 3 years old) have less favorable outcome.

  • This study reports on a series of adult patients with confirmed ependymoma treated at The University of Texas M. D.
  • Patients aged >17 and with ependymoma were identified, and clinical data were collected by retrospective chart review.
  • Forty had tumors in the brain, 80 in the spine, and 3 had both.
  • The majority were Grade I/II lesions (108) vs Grade III (anaplastic; 15).
  • The most common presenting symptom was pain, with an average of 4 symptoms reported prior to diagnosis.
  • Median time to recurrence was 21 months (Grade II) brain and 18 months (Grade III).
  • Worse outcome measured by overall and progression-free survival were associated with brain location (P = .01, P = .04) and tumor anaplasia (P = .0025, P = .001).
  • Tumor grade and brain location are associated with a worse prognosis.
  • Reclassification of ependymoma by neuropathologists is common.
  • Results of this study have lead to a multicenter study to further define important diagnostic and prognostic variables for adults with ependymoma.

  • Aberrant methylation is common in malignant brain tumors of childhood and may have implications for stratification and therapy.
  • Methylation of p16 (INK4A), p14 (ARF), TIMP3, CDH1, p15 (INK4B )and DAPK1 in medulloblastoma (MB) and ependymoma has been discussed controversially in the literature.
  • We examined methylation in MB, sPNET and ependymoma using methylation-specific PCR (MSP), quantitative Combined Bisulfite Restriction Analysis (COBRA) and direct and clone sequencing of bisulfite PCR products.
  • Only p16 (INK4A )and TIMP3 were methylated consistently in medulloblastomas (p16 (INK4A ) 14%, TIMP3 11%) and p16 (INK4A) also in anaplastic ependymomas (1/4 tumors).
  • Therapeutic and diagnostic implications urge into depth analyses of methylation as a mechanism, which might fill some of the gaps of our understanding of brain tumor origin.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: The purpose of this study was to evaluate ADC values in the preoperative grading of primary infratentorial brain tumors in children.
  • All children were operated on and tumors were histopathologically proved as low-grade - 25 (24 pilocytic astrocytomas, 1 ependymoma) and high-grade lesions - 25 (19 medulloblastomas, 6 anaplastic ependymomas).
  • RESULTS: Statistically significant differences were found in the comparisons of mean ADC of pilocytic astrocytomas (1.54×10(-3)mm(2)/s ±0.2) with medulloblastomas (0.75×10(-3)mm(2)/s ±0.075) and pilocytic astrocytomas (1.54×10(-3)mm(2)/s ±0.2) with anaplastic ependymomas (0.99×10(-3)mm(2)/s ±0.25).

  • The overlap in ADC between tumor types appeared partly due to technical factors (in small, heterogeneous, calcific, or hemorrhagic tumors) but also likely reflected true histologic variability, given that our 3 overlap cases included a desmoplastic medulloblastoma, an anaplastic ependymoma, and a JPA with restricted diffusion in its nodule.

The Lens. Cited by Patents in .

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • We histologically and molecularly reviewed our pediatric brain tumors for unrecognized AT/RTs and evaluated the role of cyclin D1, a potential molecular target of hSNF5/INI1.
  • METHODS: We analyzed 16 tumors under three years of age: seven medulloblastomas, three anaplastic ependymomas (E IIIs), two each of supratentorial primitive neuroectodermal tumors (sPNETs) and choroid plexus carcinomas (CPCs), and one each of neuroblastoma and pineoblastoma.
  • Because of the presence of rhabdoid cells and the polyimmunophenotypic features, the diagnosis was revised to AT/RT in five (31%) tumors, namely, two E IIIs and one each of medulloblastoma, CPC and pineoblastoma.
  • CONCLUSION: AT/RT can be misdiagnosed as a variety of tumors, including ependymoma that potentially harbors LOH 22q.
