Abstract
Non-Hodgkin lymphoma (NHL) of the genitourinary system is a very rare disease. Only 1 % of NHL are primary genitourinary lymphomas, most commonly of testicular origin. Secondary infiltration from disseminated lymphoma can be found in all the genitourinary organs. We report on five patients with genitourinary lymphoma who were diagnosed at our department: one case of primary testicular lymphoma and four patients with secondary lymphomatous infiltration of kidney, bladder, prostate and testicles, respectively. The clinical courses are described and the current literature is reviewed. The operation could be restricted to a biopsy for assurance of the diagnosis. However, the mostly radical procedures are performed for curative purposes after an incorrect diagnosis of a malignant organ cancer without even recognizing or considering NHL in the differential diagnosis.

Abstract
Array-based comparative genomic hybridization (array CGH) enables us to detect the genomic copy number alterations of cancers with high resolution. Our established array CGH platform consists of 2,304 BAC/PAC clones covering the whole genome at 1.3-mega base resolutions. Using this technique, we were thus able to reveal disease-specific genomic alterations and the candidate target genes in various lymphomas. We herein report the characteristic genomic alterations of malignant lymphomas including diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL) and adult T cell lymphoma/leukemia (ATLL). The combined use of the array CGH data with gene expression profiling and specific gene rearrangement analyses further delineated the subtype-specific genomic alterations. For instance, we revealed that activated B-cell-like DLBCL is characterized by a gain of chromosome 3, 18q and loss of 9 p21, whereas the germinal center B-cell-like DLBCL is characterized by a gain of 2p15, 7q, and 12q. Among these genomic alterations,we found the 9 p21 loss (p16INK4a locus) to be the most aggressive type of DLBCL. Comparisons of the genome profiles of FL,both with and without BCL2 rearrangement, also revealed the existence of a unique subgroup: trisomy 3 FL. Comparison of genome profiles between acute type and lymphoma types of adult T cell lymphoma also demonstrated that acute and lymphoma types are genomically distinct subtypes, and thus may develop tumors via distinct genetic pathways. In addition to identifying disease-specific genomic alterations, we also discovered several target genes of the genomic gains and losses. Furthermore,we developed a computer algorithm to classify lymphoma diseases or subtypes on the basis of copy number gains and losses. We applied the algorithm to the classifications of DLBCL and MCL diseases and ABC and GCB subtypes. The method correctly classified the DLBCL and MCL diseases at 89%, and ABC and GCB subtypes at 83%. These results demonstrate that copy number gains and losses detected by array CGH could be used for classifying lymphomas into biologically and clinically distinct diseases or subtypes. The genomic copy number alterations detected by array CGH are therefore considered to have the potential to help diagnose or classify different disease entities and tumor subtypes.

Abstract
A 49-yr-old Japanese woman underwent upper gastrointestinal endoscopy because of nonspecific dyspepsia. Endoscopy revealed a flat elevated lesion about 15 mm in diameter adjacent to the duodenal papilla, the surface of which was uneven and covered with whitish granules. Based on the results of histological examination with immunohistochemistry (positive for CD10, CD20, CD79a, and bcl-2 protein, negative for CD5 and cyclin D1), a diagnosis of grade 1/3 follicular lymphoma was established. Systemic staging examinations suggested the lymphoma was restricted to the mucosa and superficial portion of the submucosa in the duodenal wall. The patient was treated with a combination of CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine, and prednisolone) and monoclonal anti-CD20 antibody (rituximab), in addition to radiotherapy. After six courses of this combination chemotherapy, complete regression of the lymphoma was observed. Although reports of small duodenal lymphoma (<20 mm or localized to the mucosa or submucosa) are extremely rare, the features of this case are characteristic of small duodenal lymphoma in terms of evolution around the ampulla of Vater, low-grade follicular type, occurrence in a women, occurrence in the fourth decade of life, and favorable outcome, and this type of tumor may need to be distinguished by pathogenesis and clinical behavior from various other gastrointestinal lymphomas.

Abstract
The aims of this study are to validate follicular lymphoma international prognostic index (FLIPI) prognostic score and to compare it with the international prognostic index (IPI) in a cohort of 57 Brazilian patients. According to IPI, 24 patients (42%) were in the low-risk, 28 (49%) in the intermediate-risk, and 4 (7%) in the high-risk group. The distribution according to FLIPI was: 20 (35%) in the low-risk, 8 (14%) in the intermediate-risk, and 29 (51%) in the high-risk group. According to IPI score, median OS was not reached for the low-risk, it was 45 months for the intermediate-risk and 25 months for the high-risk group (p < 0.001). When FLIPI score was applied, median OS was not reached for the low and intermediate-risk, and was 42 months for the high-risk group (p = 0.0064). These findings suggest that: (1) FLIPI score could be validated in a Brazilian population; (2) FLIPI is more accurate than IPI to identify FL patients having worse prognosis (51%); (3) IPI seems to be a better tool for clinical decisions because it selected a smaller high-risk group (7%) having worse prognosis. In our opinion, IPI high-risk patients are the real candidates for more aggressive therapies, avoiding unnecessary over-treatment.

Abstract
Recent gene-expression data have suggested that host immune genetic signatures may predict outcomes in patients with follicular lymphoma. We evaluated the hypothesis that germ line common variation in candidate immune genes is associated with survival. Cox models were used to estimate hazard ratios (HR) and corresponding 95% confidence intervals for individual SNPs after accounting for age, clinical, and other demographic factors. The median age at diagnosis of the 278 patients was 57 years, and 59 (21%) of the patients died during follow-up, with a median follow-up of 59 months (range, 27-78 months) for surviving patients. SNPs in IL8 (rs4073; HR(TT)=2.14, 1.26-3.63), IL2 (rs2069762; HR(GT/TT) = 1.80, 1.06-3.05), IL12B (rs3212227; HR(AC/CC)=1.83, 1.06-3.06), and IL1RN (rs454078; HR(AA)=1.93, 1.11-3.34) were the most robust predictors of survival. A summary score of the number of deleterious genotypes from these genes was strongly associated with survival (P=.001). A risk score that combined the 4 SNPs with the clinical and demographic factors was even more strongly associated with survival (P<.001); the 5-year Kaplan-Meier survival estimates were 96% (93%-100%), 72% (62%-83%), and 58% (48%-72%) for groups at low, intermediate, and high risk, respectively. Common variation in host immune genes warrants further evaluation as a promising class of prognostic factors in follicular lymphoma.

Abstract
A 75-year-old man with relapsed follicular non-Hodgkin lymphoma confined to a solitary lung mass was treated with radioimmunotherapy (RIT) using yttrium 90-ibritumomab tiuxetan. Imaging with positron emission tomography/computed tomography showed a complete response 3 months after RIT. Thirteen months after RIT, his positron emission tomography/computed tomography scan showed a fluorodeoxyglucose-avid infiltrate in the area of the previous lung mass. Bronchoscopy revealed the area to be obstructed with fibrosis, and cytologic washings and brushings did not show lymphoma. The patient remains asymptomatic, and the fluorodeoxyglucoseavid pulmonary infiltrate was unchanged 19 months after RIT. In view of the lack of respiratory symptoms or progressive imaging abnormalities, we believe radiation fibrosis is the most likely etiology. Radiation-induced lung injury after therapy with yttrium 90 was previously reported in the setting of intraarterial microspheres used to treat inoperable hepatic tumors. This is the first case in which radiation-induced radiographic changes are reported after RIT for lymphoma.

Abstract
Follicular lymphoma with gastrointestinal tract involvement is rare. We describe the case of a young woman with follicular lymphoma with multiple nodular lesions involving segments of the proximal jejunum and terminal ileum. The presenting symptom was chronic diarrhea. The diagnosis was made by endoscopy with histologic examination of the mucosal lesions of the proximal and distal small intestine, immunohistochemical staining, and molecular analysis. The initial spread and pattern of the small bowel involvement, as well as treatment response, were evaluated by videocapsule endoscopy. The application of molecular analysis along with immunophenotypic evaluation has made it possible to precisely diagnose follicular lymphoma. In the present case, the use of capsule endoscopy improved the evaluation of the extent of small bowel involvement prior to and following treatment.

Abstract
Cyclophosphamide is a chemotherapeutic agent with the potential to cause pulmonary toxicity, most commonly in the form of diffuse alveolar damage. Cyclophosphamide-induced pulmonary toxicity is extremely rare and often difficult to recognize because of presence of confounding factors, including use of other cytotoxic drugs, radiation pneumonitis, oxygen toxicity, pulmonary infections, and malignancies. The lung toxicity caused by cyclophosphamide is accelerated when cyclophosphamide is combined with amiodarone, an antiarrhythmic agent also capable of lung toxicity. We describe a patient with non-Hodgkin's lymphoma who developed fatal pulmonary toxicity after a single dose of cyclophosphamide in the setting of long-term amiodarone use.

Abstract
BACKGROUND AND OBJECTIVES In follicular lymphoma histological grading is used to predict clinical behavior and to stratify patients for treatment. However, the reproducibility of histological grading is poor and the clinical significance of the difference between grade 1 and grade 2 follicular lymphoma is unclear. Data on proliferation characteristics with respect to prognosis in follicular lymphoma are inconsistent. DESIGN AND METHODS We assessed the Proliferation Index in follicles, using Mib-1 immunohistochemical staining in lymph node biopsies from 51 patients with follicular lymphoma who were receiving uniform first-line treatment consisting of cyclophosphamide, vincristine, prednisone and interferon alpha2b. RESULTS The median Proliferation Index was 16.9 (range 3.1-49.2). In grades 1 and 2 follicular lymphoma (n=45) it was 16.1, compared to 24.2 in grade 3 (n=6; p=0.02). At a median follow-up of 71 months, patients with a Proliferation Index below the median had a significantly prolonged time to progression (median not reached vs. 15 months for those with a Proliferation Index above the median; p=0.0006) and improved overall survival (median not reached vs. 42 months, respectively; p=0.002). In multivariate analysis, the Proliferation Index retained its predictive value. Additional prognostic information was especially provided in patients with a low International Prognostic Index. Histological grade did not predict outcome. INTERPRETATION AND CONCLUSIONS The Proliferation Index is a biological marker that is strongly and independently predictive for outcome in follicular lymphoma, as shown even in this relatively small series of patients. It is easily applicable and reproducible and therefore superior to histological grading in identifying clinically aggressive follicular lymphoma, requiring other types of treatment.

Abstract
We present three cases of follicular lymphoma (FL) exhibiting prominent sclerosis (sclerosing variant of follicular lymphoma), resembling inflammatory pseudotumor (IPT) of the lymph node, arising from mesenteric lymph node. Clinically all three cases represented bulky masses of the mesenteric lymph node. Histologically, the lesions were characterized by neoplastic lymphoid follicles separated by stromal collagenization and sclerotic process, with cellular infiltrate extending into the adjacent adipose tissue. The lesions contained variable cellular spindle cell proliferation and inflammatory infiltrate including numerous reactive T cells and histiocytes. Small capillary proliferation with vascular change was also noted. Immunohistochemical study demonstrated the myofibroblastic nature of the spindle cells. Moreover, neoplastic follicles were composed of intermediate to medium-sized lymphocytes, somewhat resembling reactive lymphoid aggregates. The overall histomorphological findings of the three lesions were similar to those of IPT of the lymph node. However, CD10, Bcl-2 and Bcl-6 immunostaining demonstrated the neoplastic nature of the lymphoid follicles and the lesions were diagnosed as FL grade 1. The present three cases indicate that the sclerosing variant of grade 1 FL should be added to the differential diagnosis from IPT of the lymph node.

Abstract
We evaluated the deposition of C4d in follicular lymphomas (FL) and extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT lymphoma). Deposition of C4d was detected in 118 lymphoma tissues from patients with lymphoma and in 20 reactive hyperplasia lymphadens (RHL) using immunohistochemistical methods. FL, MALT lymphoma, and RHL were studied using double staining for CD35/C4d and Bcl-2/C4d. We studied 26 FL tissues, 19 of which showed C4d deposition. C4d deposition was detected around the follicular dendritic cells (FDCs) in the neoplastic follicles. There was no significant difference between the positive ratio of C4d and the grades of FL. We studied 12 MALT lymphoma tissues, six of which displayed C4d deposition. In these tissues, C4d deposition was detected in the peripheral region of partially colonized follicles in the form of an irregular ring, but was not found in the central region. C4d deposition was negative in completely colonized follicles. There was no C4d deposition in diffuse large B-cell lymphomas, mantle cell lymphomas, B-small lymphocytic lymphomas, T-lymphoblastic lymphomas, peripheral T-cell lymphomas, and anaplastic large cell lymphomas. C4d around the FDCs in the neoplastic follicles was a specific indicator for FL. C4d deposition in partially colonized follicles of MALT lymphoma was completely different from that in neoplastic follicles of FL, forming a key point for differential diagnosis.

Abstract
Primary gastrointestinal lymphoma represents the most common location of extranodal lymphoma. With the bulk of disease manifesting within the gastrointestinal tract and contiguous lymph nodes, many of the lymphomas occurring in the peripheral lymph nodes can also present with primary gastrointestinal tract involvement. Molecular biology has recently enabled significant progress in the diagnosis and management of primary gastrointestinal lymphoma. Herein, we will discuss the major lymphomas affecting the bowel and highlight their key morphological, immunophenotypical and molecular diagnostic attributes. Similarly, in keeping with recent therapeutic advances, we will briefly discuss some important treatment considerations. Thus, this review is intended to offer clinicians and pathologists an overview of primary gastrointestinal lymphomas.

Abstract
Recent microarray gene expression profiling studies have identified gene signatures predictive of outcome, so-called "indicator" genes, for diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL). However, measurement of these genes in routine practice remains difficult. We applied real-time polymerase chain reaction (PCR) to polyA cDNAs prepared from 106 archived human frozen lymph nodes (63 of FL, 25 of DLBCL, 10 reactive lymph nodes, and cases with paired samples of FL [4] and subsequent DLBCL [4]). Reverse transcription and polyA reverse transcriptase (RT)-PCR was performed, and resultant cDNA was probed by real-time PCR for 36 candidate indicator genes, selected from microarray studies. Nine genes showed statistically significant different expression between FL and DLBCL, including cyclin B, COL3A1, NPM3, H731, PRKCB1, OVGL, ZFPC150, HLA-DQ-a, and XPB. Of these, cyclin B, NPM3, and COL3A1 were higher in DLBCL. Six genes showed statistically significant higher expression in the neoplastic nodes compared with reactive nodes, namely PRKCB1, BCL-6, EAR2, ZFX, cyclin B, YY1. High levels of YY.1 were associated with a shorter survival interval in both FL and DLBCL. The method is simple, sensitive, and robust, facilitating routine use and may be used as a platform for clinical measurement of prognostic gene signatures.

Abstract
Research on developing molecular diagnostics for hereditary cancers resulted in establishing diagnostic services for familiar polyposis and non-polyposis patients (mutation determination of APC, MYH, STK11, SMAD4, MLH1, MSH2). In familiar testicular cancers the role of gr/gr gene on Y chromosome was identified. Molecular diagnostic tool was established to monitor the progression of follicular lymphoma using Bcl-2/IgH fusion sequences. Molecular diagnostic tools were developed to monitor circulating endothelial precursor cells (CEP) as well and the technique was tested in lung cancer patients. In malignant melanoma we have tested several potential novel markers among which ryanodine receptor seems to be a promising one, while the functional P2X7 receptor may serve as a therapeutic target. We have determined the tyrosine kinase "kinome" profile of HER-2-amplified breast cancers. Furthermore, the "kinome" profile was found to be characteristic for head and neck cancers of various anatomical location. Based on previous studies on the anti-migratory and antimetastatic potential of low-molecular-weight heparins, we have identified short heparin-derived oligosaccharides with maintained antimetastatic- but non-anticoagulant potentials. Pharmacogenomic studies on the role of polymorphism of the serine-hydroxymethyl-transferase (SHMT) gene in the efficacy of 5-FU and FOLFIRI protocols of colorectal cancer patients revealed a significant effect resulting in altered overall survival as well.

Abstract
CONTEXT Primary pancreatic lymphoma is a rare form of extranodal lymphoma originating in the pancreas. The present report describes a case of follicular lymphoma of the pancreas with unique CT and MRI findings. CASE REPORT A 58-year-old male complained of sudden abdominal pain, and routine ultrasonography detected an 8 cm hypoechoic tumor in the head of the pancreas. The 3D image generated using multi-cholangiography and virtual duodenography provided the information necessary for a laparotomy. The tumor was enucleated for diagnosis. Follicular lymphoma is quite rare in the pancreas and gastrointestinal tract. A considerable number of pancreatic lymphoma subtypes have been reported. The expression "pancreatic lymphoma" has been used to describe both primary lymphoid neoplasms originating in the pancreatic parenchyma and tumors invading from a peri-pancreatic lymphadenopathy. The present case belongs to the latter, which might explain the unique imaging findings and histological type. These subtypes display different imaging findings and different clinical characteristics. In the future, primary pancreatic lymphoma should be discussed separately depending on the subtype. CONCLUSION We propose a new subtype of primary pancreatic lymphoma. Multi-cholangiography and virtual duodenography provided the information necessary for a laparotomy in the present case. Enucleation is indicated for benign and low-grade malignant tumors of the pancreas, even if the tumor is located in the head of the pancreas.

Abstract
A tissue microarray (TMA) containing diagnostic biopsies was used to develop predictors of outcome in a group of 105 patients having advanced-stage follicular lymphoma (FL). The patients were staged and uniformly treated, and the usable cases had been randomly divided into a subgroup of 50 patients with outcomes identified, and a reserved subgroup of 43 patients whose outcomes were masked for blind testing of the predictors. Using training-input data from some patients with known outcomes, parallel cascade identification developed two predictors of overall survival based on a number of biomarkers. Both predictors had statistically significant performance over the remaining patients with known outcomes. The first predictor had been identified with model architectural settings and encoding scheme chosen, for the particular training input used, to enhance classification accuracy over remaining patients in the known subgroup. The second predictor was obtained without changing the settings and encoding scheme, but from an entirely different training input corresponding to novel cases from the TMA. Not surprisingly, the first predictor showed much higher accuracy over the known subgroup, but when tested over the reserved subgroup of 43 patients, averaged about 58% correct and did not reach statistical significance. The other predictor performed very similarly over the known and the reserved subgroups, with prediction on the reserved subgroup highly significant at p = 0.0056 in Kaplan-Meier survival analysis. We conclude that a predictor based on a number of biomarkers obtainable at diagnosis has the potential to improve prediction of overall survival in FL.
