Abstract
Acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) is a heterogeneous hematological disorder defined by morphological, genetic, and clinical features. Patients with AML-MRC often show cytogenetic changes, which are associated with poor prognosis. Straightforward criteria for AML-MRC diagnosis and a more rigorous characterization of the genetic abnormalities accompanying this disease are needed. Here we describe an informative AML-MRC case, showing two separate, but concurrent, chromothripsis events, occurred at the onset of the tumor, and originating an unbalanced t(5;7) translocation and a derivative chromosome 12 with a highly rearranged short arm. Conversely, despite chromothripsis has been often associated with genomic amplification in cancer, in this case a large marker chromosome harboring amplified sequences from chromosomes 19 and 22 arose from a stepwise mechanism. Notably, the patient also showed a TP53 mutated status, known to be associated with an increased susceptibility towards chromothripsis and a poor prognosis. Our results indicate that multiple chromothripsis events may occur early in neoplastic transformation and act in a synergistic way with progressive chromosomal alterations to determine a dramatic impact on disease outcome, as suggested by the gene expression profile analysis.

Abstract
The identification of chromosome 1 translocations and deletions is a rare and poorly investigated event in chronic lymphocytic leukemia (CLL). Nevertheless, the identification of novel additional molecular alterations is of great interest, opening to new prognostic and therapeutic strategies for such heterogeneous hematological disease. We here describe a patient affected by CLL with a mutated IGHV status, showing a balanced t(1;3)(q23.1;q21.3) translocation and a der(18)t(1;18)(q24.2;p11.32), accompanying the recurrent 13q14 heterozygous deletion in all analyzed cells at onset. By combining whole-genome sequencing, SNP array, RNA sequencing, and FISH analyses, we defined a 1q23.1 biallelic minimally deleted region flanking translocations breakpoints at both derivative chromosome 1 homologues. The deletion resulted in the downregulation of the Fc receptor-like family genes FCRL1, FCRL2, and FCRL3 and in the lack of expression of FCRL5, observed by RT-qPCR. The mutational status of TP53, NOTCH1, SF3B1, MYD88, FBXW7, and XPO1 was investigated by targeted next-generation sequencing, detecting a frameshift deletion within NOTCH1 (c.7544_7545delCT). We hypothesize a loss of tumor suppressor function for FCRL genes, cooperating with NOTCH1 mutation and 13q14 genomic loss in our patient, both conferring a negative prognosis, independently from the known biological prognostic factors of CLL.

Abstract
BACKGROUND AND STUDY AIMS Colorectal cancer (CRC) screening with biennial fecal occult blood test has been shown to reduce CRC mortality. For the effectiveness of the CRC screening program is crucial that a high-quality colonoscopy with a high adenoma detection rate (ADR) be performed. To improve ADR, various endoscopic devices have been developed. Endocuff, an endoscopic cap with finger-like projections, has been shown to improve ADR. The aim of this study was to compare in an organized CRC screening program ADR, advanced adenoma detection rate (AADR) and mean number of adenomas per patient (MAP) using standard colonoscopy (SC) and Endocuff-assisted colonoscopy (EAC). PATIENTS AND METHODS We compared performance of SC (in 2014) and EAC (in 2015) in consecutive participants in an organized CRC screening program. RESULTS SC and EAC were performed in 546 (284 males) and 519 (293 males) subjects, respectively (mean age 60 years). Cecal intubation rate was 97.4 % for SC and 97.1 % for EAC and not significantly different ( P = 0.7). ADR was 47 % for SC and 52 % for EAC, P = 0.1. MAP in SC and EAC were 0.87 (range: 0 - 7) and 1.11 (range: 0 - 13) respectively, P = 0.02. AADR rate was 25 % and 23 % for SC and EAC, respectively, P = 0.5. CONCLUSION Endocuff-assisted colonoscopy does not improve the number of patients with at least one adenoma but it may increase the number of detected adenomas per procedure.

Abstract
Background The progression of low-risk del(5q) myelodysplastic syndrome to acute myeloid leukemia is increased when associated with mutations of TP53, or with additional chromosomal abnormalities. However, to date the prognostic impact and molecular consequences of these rearrangements were poorly investigated. Single additional alterations to del(5q) by balanced chromosome rearrangements were rarely found in myelodysplasia. In particular, balanced alterations involving TP63 and FOXP1 genes were never reported in the literature. Case presentation Here we report on a 79-year woman with an aggressive form of myelodysplastic syndrome with del(5q), no TP53 mutation, and a novel complex rearrangement of chromosome 3 in bone marrow cells. Our results revealed that the FOXP1 and TP63 genes were both relocated along chromosome 3. Strikingly, immunohistochemistry analysis showed altered protein levels, disclosing that this rearrangement triggered the expression of FOXP1 and TP63 genes. FOXP1 was also found activated in other patients with myelodysplasia and acute myeloid leukemia, showing that it is an important, recurrent event. Conclusions We document an apparent role of FOXP1 and TP63, up to now poorly documented, in the progression of MDS in our patient who is lacking mutations in the TP53 tumor suppressor gene normally associated with poor outcome in myelodysplastic syndrome with 5q-. Finally, our results may suggest a possible broader role of FOXP1 in the pathogenesis and progression of myelodysplasia and acute myeloid leukemia.

Abstract
Intravascular lymphoma is a rare subtype of diffuse large B cell lymphoma, characterized by proliferation of mature B cells within the lumina of small and medium vessels of many organs, without parenchymal involvement. The clinical phenotype is extremely variegated; moreover, neurological symptoms such as encephalopathy and focal neurological deficits occur and often coincide with disease's debut. We described the clinical course of a patient with intravascular diffuse large B cell lymphoma presented with subacute cognitive decline without focal signs, later associated to aspecific general symptoms that rapidly evolved to a severe inexplicable encephalopathy accompanied to systemic failure.

Abstract
Well-established histopathological prognostic factors are lacking in primary central nervous system (CNS) lymphomas (PCNSL). The present study investigated the presence and prognostic role of tumour necrosis (TN) and reactive perivascular T-cell infiltrate (RPVI), defined as a rim of small reactive T-lymphocytes occurring alone or located between the vascular wall and large neoplastic cells, in tumour samples from 100 immunocompetent patients with PCNSL. World Health Organization histotypes of the patients were: 96 diffuse large B-cell lymphomas, two Burkitt-like lymphomas, one anaplastic large T-cell lymphoma and one unclassified B-cell lymphoma. TN was observed in 24 (24%) cases and RPVI in 26 (36%) of 73 assessable cases. Patients with RPVI-positive lesions exhibited a significantly better overall survival (OS) than patients with RPVI-negative lymphoma, particularly among patients treated with high-dose methotrexate-based chemotherapy (3-year OS: 59 +/- 14% vs. 42 +/- 9%, P = 0.02). By contrast, the presence of TN did not demonstrate prognostic significance. Multivariate analysis confirmed an independent association between RPVI and survival. In conclusion, the presence of RPVI is independently associated with survival in PCNSL. This parameter can be easily and routinely assessed at diagnosis on histopathological specimens.

Abstract
Purpose To date, no data are available on the relationship between 1p/19q deletions and the response to temozolomide (TMZ) in primary anaplastic oligodendroglioma (AO) and anaplastic oligoastrocytoma (AOA) recurrent after surgery and standard radiotherapy. The aim of this study was to evaluate correlations between 1p/19q deletions, O6-methylguanine DNA methyltransferase (MGMT) promoter methylation, and response rate to TMZ in this setting. Patients and Methods From June 2000 to February 2005, 67 patients were enrolled; 39 patients (58%) had AO and 28 patients (42%) had AOA. All patients received 150 to 200 mg/m2 of TMZ every 28 days. Chromosome 1p and 19q deletions were detected by fluorescence in situ hybridization and MGMT promoter methylation was analyzed using methylation specific polymerase chain reaction. Results The overall response rate was 46.3% (17 complete responses and 14 partial responses). The response rate was higher in patients with AO than in those with AOA (61.5% v 25%, P = .003). Combined 1p/19q allelic loss was found in 32 patients (47.8%), while MGMT methylation occurred in 37 (68.5%) of 54 assessable patients. 1p/19q loss was significantly correlated with response rate (P = .04), time-to-progression (P = .003), and overall survival (P = .0001). Despite the significant concordance found between MGMT promoter methylation and 1p/19q deletions (P = .02), MGMT promoter methylation showed only a borderline correlation with overall survival (P = .09). Conclusion TMZ is active in anaplastic oligodendroglial tumors treated at first recurrence. In this setting, 1p/19q allelic loss is an important predictive and prognostic factor. Further studies on MGMT promoter methylation should be performed in randomized trials to test its correlation with survival.

Abstract
Background Intra-thoracic desmoid tumours with mediastinal invasion are very rare. Although rare they have to be taken into account in the differential diagnosis of a thoracic mass and therapeutic options have to be weighted since surgical treatment may require wide excision. Case presentation A 48-year-old male diabetic, dyslipidaemic, former heavy smoker with psychiatric illness was operated by sternotomy for a triple aorto-coronary bypass 4 years before, presented with complains of recent onset such as constant and oppressive chest pain. At surgery a mass extending from the aortic arch into the entire anterior mediastinum and to most of the right pleural cavity was found. The mass was separated from sternal periosteum and vessels of aorto-coronary by pass were isolated starting from the aortic arch up to the pericardium. The histological examination revealed aggressive fibromatosis. Conclusion Although technically demanding, radical surgical excision is actually the most indicated therapeutic approach for intra-thoracic desmoid tumours.

Abstract
We compared survival in patients with anaplastic astrocytoma (AA) treated with adjuvant procarbazine, lomustine, and vincristine (PCV) with survival in patients treated with temozolomide. A retrospective analysis was made of patients with newly diagnosed AA treated with adjuvant postradiotherapy chemotherapy. Outcome analysis included progression-free survival and overall survival. The following prognostic factors were taken into account: patient age, extent of resection, performance status, presence of contrast enhancement in presurgical imaging, and type of adjuvant treatment. Among 109 AA patients, 49 were treated with PCV and 60 with temozolomide. The treatment groups were well matched for pretreatment characteristics, except for the presence of contrast enhancement. Age, extent of surgery, performance status, and presence of contrast enhancement were statistically significant prognostic factors according to the Cox model analysis of survival. Type of adjuvant chemotherapy was not a significant factor, either for progression-free survival or for overall survival. Hematological toxicity, nonhematological toxicity grades 3-4, and premature discontinuation due to toxicity were observed in 9%, 3% to 5%, and 37%, respectively, of cases in the PCV group versus 4% to 5%, 0, and 0, respectively, in the temozolomide group. Although the present study was not randomized, it was well designed, and it reports on two homogeneous and consecutive series of patients, for whom histology was verified to obtain survival data only for patients with AA following the recent WHO 2000 classification. Even if no survival advantage has been demonstrated for temozolomide versus PCV, we conclude that temozolomide should be preferred because of its greater tolerability.

Abstract
BACKGROUND To the authors' knowledge, there is a scarcity of accurate data regarding the feasibility of standard chemotherapy with procarbazine, lomustine, and vincristine (PCV) in a homogeneous series of patients with primary anaplastic oligodendroglioma (AO) and oligoastrocytoma (AOA) that was recurrent after surgery and standard radiotherapy. The aim of the current study was to evaluate the overall response rate, toxicity, and time to progression (TTP) with the use of standard PCV in this setting. METHODS Between November 1994 and September 2000, 37 patients were enrolled in the current study. Of these, 23 had AO (62%) and 14 had AOA (38%). All patients received standard PCV comprised of lomustine (110 mg/m2) on Day 1, procarbazine (60 mg/m2) on Days 8-21, and vincristine (1.4 mg/m2, maximum total 2 mg) on Days 8 and 29. Cycles were repeated every 6 weeks. RESULTS There were 11 complete responses (CR; 29.7%) and 11 partial responses (PR; 29.7%) reported and 8 patients had stable disease (SD; 21.6%). The response rate was higher in patients with AO compared with patients with AOA (77.2% vs. 22.7%; P = 0. 02). The median TTP, which was 12.3 months overall, was 30.3 months in patients who achieved a CR, 19.1 months in patients who achieved a PR, and 6.1 months in patients with SD. The median TTP was 18.6 months in AO patients and 6.14 in AOA patients. There were no cases of severe toxicity reported although in 16 patients (43%) who were free of disease progression, PCV was discontinued because of toxicity or inadequate recovery after 2 weeks of delay. CONCLUSIONS PCV chemotherapy was reported to achieved a high response rate and TTP but incurred a high risk of persistent toxicity.

Abstract
We investigated the prevalence and prognostic role of CpG island methylation of the reduced folate carrier (RFC) gene promoter region in primary central nervous system lymphoma (PCNSL) in immunocompetent patients. Genomic DNA from 40 PCNSL was used for methylation-specific polymerase chain reaction and bisulphite genomic sequencing of the RFC promoter region. Human immunodeficiency virus-negative systemic diffuse large B-cell lymphomas (DLBCL) were used as controls (n = 50). The impact on outcome of RFC promoter methylation was assessed in 37 PCNSL patients treated with high-dose methotrexate (HD-MTX)-based chemotherapy +/- radiotherapy. RFC promoter methylation occurred in 12 of 40 (30%) PCNSL and in four of 50 (8%) DLBCL (P = 0.01). Of 37 PCNSL treated with HD-MTX-based chemotherapy, methylation occurred in nine cases (24%, M-PCNSL), while 28 cases (76%, U-PCNSL) were negative. Three M-PCNSL (33%) and 15 U-PCNSL (54%) achieved complete remission (CR) after primary chemotherapy. Logistic regression confirmed the independent association between CR rate and International Extranodal Lymphoma Study Group score (P = 0.03), RFC promoter methylation (P = 0.07) and use of cytarabine (P = 0.08). The 3-year failure-free survival (FFS) and overall survival for M-PCNSL and U-PCNSL was 0% vs. 31 +/- 9% (P = 0.34) and 0% vs. 31 +/- 9% (P = 0.35) respectively. This is the first study to assess the methylation status of the RFC promoter in human tumour samples. RFC methylation is more common in PCNSL compared with systemic DLBCL, and is associated with a lower CR rate to HD-MTX-based chemotherapy. If confirmed in prospective trials on PCNSL treated with HD-MTX alone, these data may suggest the necessity for alternative strategies in M-PCNSL considering the increased risk of MTX resistance by tumour cells.

Abstract
BACKGROUND Optimal therapeutic management of intravascular lymphoma (IVL) lacks precise guidelines. PATIENTS AND METHODS The clinico-pathological features of 38 HIV-negative patients with IVL were reviewed to define efficacy of chemotherapy in these malignancies. Clinical characteristics of 22 patients treated with chemotherapy and of 16 untreated patients were compared in order to understand better the impact and causes of potential patient selection. RESULTS Median age was 70 years (range 34-90), with a male/female ratio of 0.9; 23 (61%) patients had Eastern Cooperative Oncology Group performance status (ECOG-PS) > 1; 21 (55%) had systemic symptoms. Cutaneous lesions and anemia were significantly more common among patients treated with chemotherapy; central nervous system (CNS) and renal involvement were significantly more common among untreated patients. Chemotherapy was associated with a response rate of 59% and a 3-year overall survival of 33 +/- 11%. Five of six patients with CNS involvement received chemotherapy: four of them died early; only one patient, treated with adriamycin, cyclophosphamide, vincristine, methotrexate, bleomycin and prednisolone (MACOP-B) followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT), was alive at 19 months. High-dose chemotherapy supported by ASCT was indicated at diagnosis in another patient (43 years of age, stage I), who was alive at 71 months, and at relapse after cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) in two patients who died early after transplantation. PS < or = 1, disease limited to the skin, stage I, and use of chemotherapy were independently associated with better outcome. CONCLUSIONS Anthracycline-based chemotherapy is the standard treatment for IVL. However, survival is disappointing, with a relevant impact of diagnostic delay and lethal complications. More intensive combinations, containing drugs with higher CNS bioavailability, are needed in cases with brain involvement, and the role of high-dose chemotherapy supported by ASCT should be further investigated in younger patients with unfavorable features.

Abstract
PURPOSE To assess in a prospective trial the value of prognostic factors and the outcome of medulloblastoma in adults. METHODS AND MATERIALS Patients (> or =18 years) with a histologic diagnosis of medulloblastoma were staged according to Chang et al.'s classification (low risk: T1, T2, T3a, M0, and no residual disease after surgery; high risk: T3b-T4, any M+ or postoperative presence of residual tumor). In low-risk patients, treatment consisted of 36 Gy to the craniospinal axis, supplemented by a local tumor dose of 18.8 Gy (total dose of 54.8 Gy). In high-risk patients, 2 cycles of "up-front chemotherapy" were delivered before the same radiation therapy, followed by maintenance chemotherapy if M1, M2, or M3 disease was present. RESULTS Over a 12-year period, 36 evaluable patients were enrolled. Progression-free survival (PFS) at 5 years was higher in low-risk patients compared to the high-risk group: 76% +/- 14% (95% confidence interval [CI] = 52%-100%) vs. 61% +/- 11% (95% CI = 42%-87%). Patients with M- disease showed a significantly better outcome than M+ patients, with 75% showing PFS at 5 years vs. 45% (p = 0.01). CONCLUSION The overall PFS observed is comparable to that obtained in pediatric series and suggests that a more effective therapy must be developed for high-risk patients.

Abstract
OBJECTIVES To investigate the efficacy of temozolomide (TMZ) in relationship to progression free survival at 6 months (PFS-6), median time to progression (TTP), response rate and toxicity, a phase II study was conducted in patients with recurrent glioblastoma multiforme (GBM) following surgery plus radiotherapy and a first-line regimen based on nitrosourea, procarbazine and vincristine. METHODS Forty-two patients with GBM were administered TMZ at the dose of 150 mg/m(2)/daily for 5 days every 4 weeks. RESULTS The PFS-6 and at 12 months (PFS-12) was 24% (95% Confidence Interval [CI] = 14-42%) and 8% (CI = 2-27%), respectively, with a median TTP of 11.7 weeks (CI = 9-22 weeks). The response was assessed in all 42 patients; we observed 2 complete responses (CR) (4.7%), 6 partial responses (PR) (14.3%), and 9 stable disease (SD) (21.4%), with CR+PR = 19% (CI = 7-31%). CONCLUSION TMZ as a second line regimen is a valid option in patients with heavily pretreated GBM.

Abstract
BACKGROUND Nitrosoureas constitute the main resource of chemotherapy for glioblastoma. However, because of chemoresistance, which is intrinsic or rapidly acquired after the first administration of chemotherapy, there have been few improvements in survival. Because O(6)-alkylguanine-DNA alkyltransferase (AGT) is the main target for increasing cell sensitivity to the nitrosoureas, we postulated that preexposure to other alkylating agents might increase the therapeutic index of the nitrosoureas by saturating all the copies of AGT present in the tumor cells. OBJECTIVE To investigate the response rate, toxic effects, time from start of chemotherapy to progression of disease or exit from the study for any reason (TTP), and progression-free survival at 6 months (PFS-6) associated with a multidrug combination that could reverse resistance to carmustine (BCNU) through AGT depletion. METHODS We conducted a phase 2 study of patients with glioblastoma at first relapse or progression after surgery and standard radiotherapy. Patients were treated with 100 mg/m(2) of procarbazine on days 1 to 5, 80 mg/m(2) of BCNU on days 3 to 5, and 1.4 mg/m(2) of vincristine on day 3 every 8 weeks. RESULTS Fifty-eight patients were enrolled in the study, and all were assessable for response and toxic effects. Six patients (10.3%) had a complete response, 11 (19%) had a partial response, and 17 (29.3%) had stable disease. The median TTP was 4.8 months; 42.3% of patients had PFS-6, and 15.4% had PFS at 12 months. Response to chemotherapy was the only significant prognostic factor for TTP. Neutropenia was grade 3 in 8.6% of patients and grade 4 in 5.2% of patients, and thrombocytopenia was grade 3 in 17.2% of patients and grade 4 in 12% of patients; hepatic and pulmonary toxic effects were grade 3 in 5.2% and 8.6% of patients, respectively. CONCLUSION This regimen proved active in chemotherapy-naive patients with recurrent glioblastoma even though toxic effects were substantial.

Abstract
OBJECTIVE To characterize the therapeutic variables correlated to outcome in 370 patients with primary CNS lymphoma. METHODS Planned treatment was radiotherapy (RT) in 98 patients, chemotherapy (CHT) in 32, RT followed by CHT in 36, and CHT followed by RT in 197 patients. High-dose methotrexate (HD-MTX; 1 to 8 g/m2) was used in 169 patients and intrathecal CHT in 109. RESULTS One hundred sixteen patients are alive (median follow-up 24 months), with a 2-year overall survival of 37%. Patients treated with CHT followed by RT had improved survival with respect to patients treated with RT alone. Patients receiving HD-MTX-based primary CHT survived longer than those treated with other drugs. HD-MTX associated with other cytostatics, in particular HD-cytarabine, produced better results than HD-MTX alone. No correlation between MTX dose and survival was found. In patients receiving HD-MTX, consolidation RT or intrathecal CHT did not improve survival. Age, performance status, lactate dehydrogenase serum level, CSF protein level, site of disease, and use of HD-MTX were all predictors of survival. CONCLUSIONS Combination CHT-RT is superior to RT alone. Patients treated with primary CHT containing HD-MTX exhibited improved survival. In these patients, the addition of HD-cytarabine was associated with a better survival, whereas intrathecal CHT was not correlated to outcome. RT may be unnecessary in patients achieving complete remission after receiving HD-MTX-based primary CHT.

Abstract
BACKGROUND Cavernous angiomas (CAs) that are localized completely in the spinal epidural space are uncommon vascular malformations. Although they have increasingly been reported in the literature in recent years, diagnostic and surgical features are not clearly defined. METHODS We report five patients with pure spinal epidural cavernous angiomas (PSECAs) and review the literature, focusing on their radiologic and surgical characteristics. We also compare these tumors with other extra-axial CAs as well as with their intra-axial counterparts. RESULTS PSECAs, like all other extra-axial CAs, differ from intra-axial ones on MRI: the hemorrhagic variant is less frequent, hemosiderin rim is rare, the signal is different, and contrast enhancement is the rule. They are very similar to spinal meningiomas but they differ in their growth pattern and morphology, since they infiltrate intervertebral foramina and have an oval shape. In PSECA, intraoperative bleeding is rarely profuse, in contrast to other extra-axial CAs, especially those of the cavernous sinus. CONCLUSIONS On MRI, PSECAs and other extra-axial CAs constitute a homogeneous group since they enhance significantly. At operation, since there is rarely enough bleeding to limit removal, radical excision of PSECAs can be achieved with good results.

Abstract
We report a new case of solitary fibrous tumor (SFT) of the liver, an extremely rare neoplasm. Including the present case no more than ten cases are reported in the English-language literature. To date there is no definite proof of the origin of this tumor. Both mesothelial and fibroblas-tic genesis has been postulated. The monoclonal antibody CD 34 has recently been used for the characterization of SFT. SFT would appear to be histogenetically related to a CD 34 - positive fibroblastic stem cell. A 61-year-old woman was admitted to our department with epigastric and right hypochondriac pain, weight loss, and hypoglycemia. Ultrasonography and computed tomography demonstrated a large heterogeneous mass in the right hepatic lobe. A right hepatectomy was performed. The tumor weighed 2850 g and microscopic section revealed a peculiar random pattern, the so-called patternless pattern of spindle tumor cells separated by abundant thick collagen bands. The tumor presented a number of highly cellular areas composed of plump spindle cell with hyperchromatic nuclei and rare mitotic figures. Ninety percent of the neoplastic cells displayed strong immunoreactivity for CD 34/My 10. The postoperative course was uneventful and the patient is alive and well without recurrence 6 years after surgery.

Abstract
SV40 T antigen (Tag) coding sequences were detected by PCR amplification followed by Southern blot hybridization in human brain tumors and tumor cell lines, as well as in peripheral blood cells and sperm fluids of healthy donors. SV40 early region sequences were found in 83% of choroid plexus papillomas, 73% of ependymomas, 47% of astrocytomas, 33% of glioblastoma multiforme cases, 14% of meningiomas, 50% of glioblastoma cell lines, and 33% of astrocytoma cell lines and in 23% of peripheral blood cell samples and 45% of sperm fluids from normal individuals. None of the 13 normal brain tissues were positive for SV40 DNA, nor were seven oligodendrogliomas, two spongioblastomas, one neuroblastoma, one meningioma, or four neuroblastoma cell lines. Expression of SV40 early region was found by reverse transcription PCR, and SV40-specific Tag was detected by indirect immunofluorescence in glioblastoma cell lines. DNA sequence analysis, performed in four positive samples, confirmed that the amplified PCR products belong to the SV40 early region. Sixty-one % of the neoplastic patients positive for SV40 sequences had an age excluding exposure to SV40-contaminated polio vaccines, suggesting a contagious transmission of SV40. The possible role of SV40 Tag in the etiopathogenesis of human brain tumors and the spread of SV40 by horizontal infection in the human population are discussed.

Abstract
Immunohistochemistry is a powerful diagnostic adjunct in the differential diagnosis between malignant mesothelioma (especially of the epithelial type) and adenocarcinoma metastatic to the serous membranes. Most of the immunological probes commonly used, however, recognize antigens expressed by the epithelial malignancies and absent from mesothelial cells and mesotheliomas. Probes suitable for the positive identification of mesotheliomas are comparatively scarce and much less commonly used because of their reduced sensitivity and specificity, their unsuitability for staining routinely fixed and embedded tissues, or their lack of commercial availability. We now document that two different polyclonal antisera to calretinin consistently immunostain mesothelial cells and malignant mesotheliomas both in routinely fixed and embedded tissue sections and in cytological preparations of serous effusions. The diagnostic sensitivity of this novel immunocytochemical approach reached 100%, allowing immunostaining of all 44 mesotheliomas investigated, which included five biphasic and three sarcomatoid types. The specificity of calretinin immunoreactivity was checked against 294 adenocarcinomas of different origin (19 serosal metastases and 275 primary tumors potentially able to metastatize to serosal membranes) relevant for the discussion of the differential diagnosis with malignant mesothelioma: only 28 cases showed focal immunoreactivity for calretinin. We conclude that calretinin is a most useful marker for the positive identification of malignant mesotheliomas.

Abstract
Three members of the same family were studied, all of whom had multiple intracerebral cavernous angiomas for which a dominant autosomal inheritance was hypothesised. The proband suffered from headaches, and physical examination revealed evident right hemiparesis. The second case started with a hemorrhagic cerebral stroke and the third was asymptomatic on neurological examination. Nuclear magnetic resonance (NMR), performed in two of the three cases, showed lesions whose number and extent were not radiologically characteristic of cavernous angioma. A cerebral biopsy of the proband enabled the diagnosis to be made. Despite the recent introduction of NMR, the nosological classification of familial forms can be difficult when the radiological lesions are atypical. In such cases, cerebral biopsy is not only a valid diagnostic aid, but is also indispensable for obtaining adequate genetic information.

Abstract
A retrospective uni-multivariate statistical analysis was performed on 32 prognostic factors to investigate their importance in predicting survival in a series of 76 adult patients with low-grade supratentorial astrocytomas treated over a 13-year period. The end point used for this study was the length of survival. The median survival time was 40 months. Overall actuarial survival at 2, 5, and 10 years was 69%, 38%, and 22%, respectively. Radical resection of the neoformation, a higher preoperative Karnofsky performance status (KPS) score, and an age younger than 50 years are strongly correlated with survival; postoperative radiotherapy appears to be associated with increased survival only in patients under 50 years of age.

Abstract
A 51 year-old male, complaining of progressive left-sided hearing loss, tinnitus, and unsteady gait, underwent surgery with a probable diagnosis of intracanalicular acoustic neuroma, based on neurological, neurotologic, Computed Tomography (CT), and Magnetic Resonance Imaging (MRI) findings. During surgery, the Internal Auditory Canal (IAC) was opened and a reddish-colored, soft, vascular lesion was found within the VII and VIII cranial nerve complex. The lesion, which resulted to be a cavernous malformation, was removed without any postoperative deficits. This report stresses the diagnostic difficulty to differentiate preoperatively the more frequent acoustic neuromas from other lesions that may develop within the IAC.

Abstract
The frequency of AIDS-associated primary central nervous system (PCNS) lymphoma is rapidly increasing in adults and children. In AIDS-related PCNS lymphoma, different authors have reported an overall poorer response rate to conventional radiation compared with immunocompetent patients. This poorer response consists of a significantly positive, although transient effect on survival following radiotherapy (XRT), with a poor toleration for prolonged whole-brain RT (WBR) and with radiation-induced changes within the normal CNS tissue on autopsy examinations after a course of XRT. These observations led us to consider highly focused single-session radiosurgical treatments as a potentially useful therapeutic modality for AIDS-associated PCNS lymphomas. A multi-institutional diagnostic and therapeutic protocol for the evaluation and treatment of AIDS patients with high-risk intracerebral space-occupying lesions has been developed at the University Hospital of Verona. Therapy is based on tumor biopsy. Tumors < or = 3.5 cm in diameter are subjected to Gamma Knife radiosurgery, whereas tumors < or = 4.5 cm are treated with stereotactic brachytherapy. At the Department of Neurosurgery, Verona, Italy, Gamma Knife treatment was performed in 2 cases of deep-seated histologically verified malignant non-Hodgkin's lymphoma. A short-term cliniconeuroradiological follow-up (2 months later) showed neurologic improvement and virtually complete disappearance of the tumor in both patients. The excellent local control and the well-tolerated single-session treatment and absence of brain toxicity signs on CT scan indicate a putative role for Gamma Knife radiosurgery in the treatment of these patients.

Abstract
The immunohistochemical expression of p53 protein (p53) was examined in 52 patients out of a series of 66 patients with low-grade astrocytomas with long-term follow-up. All patients were also evaluated for several clinical and histological features, among which only preoperative Karnofsky score and the extent of surgery were statistically significant parameters to predict outcome on multivariate analysis. p53 accumulation was seen in 46.1% of patients, with a wide range of percentage of positive cells. Median survival for p53-positive and p53-negative patients was 41 and 37 months respectively. The survival curves of p53-positive and -negative patients were not statistically different. However, the curves showed a trend towards a more aggressive course in p53-positive patients beginning 3-4 years after surgery. Five years after diagnosis the survival estimate with the Kaplan-Meier method was 21.2% for patients with p53-positive tumours and 45.9% for patients with p53-negative tumours. This trend is not due to different distribution of major clinical prognostic factors (age, incomplete resection or Karnofsky status). The trend could be related to the time needed by the p53-positive clone to outgrow the rest of the p53-negative neoplastic cell population. This hypothesis is further supported by the fact that the five recurrences which were surgically removed (one anaplastic astrocytoma and four glioblastomas) derived from p53-positive tumours and were themselves intensely p53 positive.

Abstract
A case of atypical carcinoid with peculiar histological and ultrastructural pattern and immunohistochemical phenotype is presented. The neoplasm is composed of three types of cells. Type 1 cells are small to medium sized, fusiform, with scarce cytoplasm and are arranged in fascicles. Type 2 cells are cuboidal and line acinar structures. Type 3 cells have more abundant eosinophilic cytoplasm, larger nuclei and are arranged in fascicles intersecting with fascicles of type 1 cells, and sometimes surround acinar structures. The three cell types are present both in the primary lesion and in its lymph node metastases. Immunohistochemistry demonstrates immunoreactivity of all cell types for general neuroendocrine markers. Cytokeratin immunoreactivity is more prominent in type 1 and 2 cells, and is only focally expressed in type 3 cells. Type 3 cells are also immunoreactive for glial fibrillary acidic protein (GFAP), alpha-actin, S-100 protein, vimentin. Electron microscopic examination confirms the neuroendocrine nature of the cells, and show that type 3 cells have prominent bundles of intermediate filaments, electron-dense granules and junctional complexes. To our knowledge, this is the first case of atypical lung carcinoid with GFAP immunoreactivity. The nature of type 3 GFAP positive cells is unclear. There are some clues pointing to their sustentacular nature, and other ones pointing to a myoepithelial origin, but the data are inconclusive. Type 3 cells may be the malignant counterpart of sustentacular cells seen in typical carcinoids, but their GFAP positivity and the presence of electron-dense granules are very unique features, which differentiates them from sustentacular cells. Alternatively, their unusual GFAP + immunohistochemical phenotype may be due to aberrant expression of cytoskeletal proteins.

Abstract
Three cases of rhabdoid tumour of the central nervous system arising in a supratentorial location are reported. The patients were 18, 14, and 7 years old. All three tumours showed a common morphology. The neoplastic cells were usually globoid with round nuclei and prominent nucleoli and large acidophilic, cytoplasmic inclusions were present in many of them. These inclusions showed strong immunoreactivity for vimentin, weak immunoreactivity for epithelial membrane antigen and focal immunoreactivity for cytokeratins. Ultrastructurally they were made up of whorls of intermediate filaments, 8-10 nm in thickness. Rhabdoid tumours of the central nervous system, whatever the cell of origin, appear to be an independent entity with identifiable histology and aggressive behaviour.

Abstract
AIMS To demonstrate, immunohistochemically, p53 protein expression in a selection of central nervous system tumours; to investigate the relation between p53 expression and that of the proliferation related antigen, PCNA. METHODS Surgical specimens from 86 central nervous system tumours were routinely fixed, paraffin wax embedded, and immunostained with a monoclonal (PAb 1801) and a policlonal antibody (CM1) p53 protein and a monoclonal antibody against PCNA (PC10). Normal brain samples obtained at necropsy and 10 surgically obtained samples of gliotic brain parenchyma were also immunostained. RESULTS p53 protein expression was observed in 35 of 86 brain tumours, suggesting frequent p53 gene mutation. p53 protein alterations were associated with all grades of malignancy in tumours displaying solely astrocytic differentiation, with the exception of pilocytic astrocytomas. In those showing oligodendroglial or ependymal differentiation they appeared to be restricted almost to only high grade lesions. No p53 immunoreactivity was observed in normal or gliotic brain tissue; p53 altered expression was not related to the percentage of PCNA labelled cells. CONCLUSIONS The use of sophisticated gene amplification techniques or highly sensitive immunohistochemical methods might be useful in distinguishing between reactive and neoplastic astrocytic lesions, and in the identification of malignant progression in other non-astrocytic glial tumours. Tumours with very similar histogenetic differentiation features might actually be a genetically heterogeneous group with possible different clinical courses.

Abstract
The occurrence and the distribution of cytokeratin (CK)-immunoreactive reticulum cells in a series of normal and pathological human lymph nodes and spleens are documented. The immunoreactive cells exhibit morphological and immunophenotypic features of so-called fibroblastic reticulum cells, with or without myoid differentiation. They invariably co-express vimentin and, to a lesser extent, desmin and muscle-specific actin isoforms. These CK-immunoreactive cells are apparently a normal subpopulation of reticulum cells, being detectable from the early stages of spleen and lymph node development. They are distributed mainly in the paracortical and medullary regions of the lymph nodes and at the periphery of the white pulp in the spleen. Their number and distribution are highly variable in different neoplastic and non-neoplastic pathological conditions but the changes are not disease specific. CK-immunoreactive reticulum cells are easily identifiable in both frozen and fixed lymphoid tissue and in cytological smears of fine-needle aspirates, provided that monoclonal antibodies whose spectrum of reactivity includes cytokeratins 8 and 18 are used. The awareness of the occurrence of CK-immunoreactive cells in normal lymphoid tissues is of particular relevance in the search for micrometastatic foci using anti-CK antibodies.

Abstract
Immunocytochemical investigation was performed on a large series of adult, neonatal, and fetal respiratory tract cartilages to ascertain their immunoreactivity for glial fibrillary acidic protein (GFAP) and vimentin. Two polyclonal and six different monoclonal antibodies were used to document the presence of GFAP-immunoreactive chondrocytes in all the fetal and neonatal cartilages as well as in the adult epiglottis, arythenoids, and lobar, segmental, and subsegmental bronchi. The number of chondrocytes showing GFAP immunoreactivity decreased from fetal life to adulthood. Simultaneous immunoreactivity for GFAP and vimentin has also been ascertained in chondrocytes and in perichondrial stellate or elongated cells of the 25 chondromatous hamartomas investigated. These findings document yet another "inappropriate" pattern of intermediate filament immunoreactivity in normal and neoplastic human cells, and contradict the widely held supposition that the expression of GFAP is restricted to cells of glial origin.

Abstract
Two adult cases of a cutaneous lesion indistinguishable from typical infantile digital fibromatosis are added to the unique similar case so far reported in adulthood. The immunocytochemical localization of vimentin and muscle actin in the proliferating cells confirms their myofibroblastic nature and establishes closer relationships between the adult and the infantile variants of this entity. These two variants, however, appear to be clinically different, since all the adult cases were extradigital and did not recur after surgical excision. The term inclusion body fibromatosis underlines the histological hallmark of the lesion and should be used to identify this entity in place of recurrent infantile digital fibromatosis which does not seem any longer appropriate.

Abstract
A case of primary ependymoma of the mediastinum is reported. The tumor was adherent to the lung and metastasized to adjacent mediastinal lymph nodes. An autopsy showed no evidence of tumor in the central nervous system. The diagnosis of ependymoma was confirmed by the immunohistochemical positivity for glialfibrillary acidic protein. To the best of our knowledge, this is the first reported example of an ependymoma in this location.

Abstract
The pathological findings of five cases of amyloidosis associated with Cystic Fibrosis are reported. Rectal biopsy led to the diagnosis of amyloidosis in four patients. In three cases the diagnosis was confirmed at autopsy, with involvement of spleen, liver, kidneys, adrenal glands, thyroid and other organs. It seems that Secondary Amyloidosis provokes a significant, although rare, complication of Cystic Fibrosis as greater numbers of these patients survive into adulthood.

Abstract
Sixteen choroid plexus tumors (CPTs) have been investigated for the localization of different immunocytochemical markers of epithelial and nonepithelial nature, namely, simple epithelial-type cytokeratins, vimentin, glial fibrillary acidic protein (GFAP), a panepithelial antigen defined by the lu-5 monoclonal antibody (lu-5 antigen), S-100 protein, and epithelial membrane antigen (EMA). Intermediate filament proteins have been identified in paraffin sections of 14 of 16 cases (87.5%). In all these tumors, cytokeratins and vimentin were constantly coexpressed by the neoplastic cells, in a manner similar to that of the cells lining normal choroid plexus. In 7 of these 14 cases, in addition to cytokeratins and vimentin, the neoplastic cells were shown to coexpress GFAP, which is not synthesized by their normal cell counterpart. The appearance of GFAP immunoreactivity in CPTs might be related to an ependymal differentiation of the neoplastic cells, because normal ependyma and ependymomas constantly coexpress GFAP and vimentin. The simultaneous expression of three distinct intermediate filament proteins by the same neoplastic cells is an exceedingly rare phenomenon, which has never been reported by double labeling technique in neoplasms of the central nervous system. Despite the complex antigenic profile of the CPT, which includes immunoreactivity for lu-5 antigen, S-100 protein, and EMA in most of the cases, positivity for three different epithelial markers indicates that these tumors have an epithelial nature. Moreover, the immunocytochemical typing of CPT with the panel of antibodies used in the current investigation allows differentiation from other primary and metastatic central nervous system tumors.
