There are no studies comparing the prognosis for mature T-cell lymphoma (TCL) in people with human immunodeficiency virus (PWH) to people without HIV (PWoH) and to AIDS-defining B-cell lymphomas (A-BCL) in the modern antiretroviral therapy (ART) era. NA-ACCORD and COMPLETE are cohorts that enroll patients diagnosed with HIV and TCL, respectively. In our study 52, 64, 101, 500 and 246 PWH with histological confirmation of TCL, primary CNS, Burkitt's, diffuse large B-cell lymphoma (DLBCL) and Hodgkin's lymphoma (HL) respectively and 450 TCL without HIV were eligible for analysis. At the time of TCL diagnosis, Anaplastic large-cell lymphoma (ALCL) was the most common TCL subtype within PWH. While PWH with TCL diagnosed between 1996-2009, experienced a low 5-year survival probability at 0.23 (95% CI: 0.13, 0.41), we observed a marked improvement in their survival when diagnosed between 2010-2016 (0.69; 95% CI: 0.48, 1; p=0.04) in contrast to TCL among PWoH (0.45; 95% CI: 0.41, 0.51; p=0.53). Similarly, PWH with ALCL diagnosed between 1996-2009 were associated with a conspicuously inferior 5-year survival probability (0.17; 95% CI: 0.07, 0.42) and consistently lagged behind A-BCL subtypes such as Burkitt's (0.43; 95% CI:0.33, 0.57; p=0.09) and DLBCL (0.17; 95% CI: 0.06, 0.46; p=0.11) and behind HL (0.57; 95% CI: 0.50, 0.65; p <0.0001). Despite a small number, those diagnosed between 2010-2016, experienced a remarkable improvement in survival (0.67; 95% CI: 0.3, 1) in comparison to PWoH (0.76; 95% CI: 0.66, 0.87; p=0.58). Thus, our analysis confirms improved overall survival for aggressive B and T-cell malignancies among PWH in the last decade.

In this review, we examine the genomic landscapes of lymphomas that arise from B, T, and natural killer cells. Lymphomas represent a striking spectrum of clinical behaviors. Although some lymphomas are curable with standard therapy, the majority of the affected patients succumb to their disease. Here, the genetic underpinnings of these heterogeneous entities are reviewed. We consider B-cell lymphomas, including Burkitt lymphoma, diffuse large B-cell lymphoma, Hodgkin lymphoma, and primary mediastinal B-cell lymphoma. We also examine T-cell lymphomas, including anaplastic large-cell lymphoma, angioimmunoblastic T-cell lymphoma, cutaneous T-cell lymphoma, adult T-cell leukemia/lymphoma, and other peripheral T-cell lymphomas. Together, these malignancies make up most lymphomas diagnosed around the world. Genomic technologies, including microarrays and next-generation sequencing, have enabled a better understanding of the molecular underpinnings of these cancers. We describe the broad genomics findings that characterize these lymphoma types and discuss new therapeutic opportunities that arise from these findings.

Primary cutaneous lymphomas (PCLs) represent a heterogeneous group of extranodal T- and B-cell malignancies. The underlying molecular pathogenesis of this malignancy remains unclear. This study aimed to characterize oncogene abnormalities in PCLs. Using genomic microarray, we detected oncogene copy number gains of RAF1(3p25), CTSB (8p22), PAK1 (11q13), and JUNB (19p13) in 5 of 7 cases of mycosis fungoides (MF)/Sezary syndrome (SS) (71%), gains of FGFR1 (8p11), PTPN (20q13), andBCR (22q11) in 4 cases (57%), and gains ofMYCL1 (1p34), PIK3CA (3q26), HRAS(11p15), MYBL2 (20q13), and ZNF217 (20q13) in 3 cases (43%). Amplification of JUNB was studied in 104 DNA samples from 78 PCL cases using real-time polymerase chain reaction. Twenty-four percent of cases, including 7 of 10 cases of primary cutaneous CD30+ anaplastic large-cell lymphoma (C-ALCL), 4 of 14 MF, 4 of 22 SS, and 2 of 23 primary cutaneous B-cell lymphoma (PCBCL) showed amplification ofJUNB, and high-level amplification of this oncogene was present in 3 C-ALCL and 2 MF cases. JUNB protein expression was analyzed in tissue sections from 69 PCL cases, and 44% of cases, consisting of 21 of 23 SS, 6 of 8 C-ALCL, 5 of 10 MF, and 9 of 21 PCBCL, demonstrated nuclear expression of JUNB by tumor cells. Overexpression of JUNB also was detected in 5 C-ALCL and 2 SS cases. These results have revealed, for the first time, amplification and expression patterns of JUNB in PCL, suggesting thatJUNB may be critical in the pathogenesis of primary cutaneous T-cell lymphomas.

Abstract Primary dural lymphoma is rare, and few of the small number of cases reported to date have been classified using immunohistochemical techniques. To our knowledge, we report the first case of T-cell–rich B-cell lymphoma (diffuse mixed small cell and large cell) presenting as a solitary intracranial dural mass. Cytologic and frozen sections prepared during intraoperative consultation revealed a polymorphic population of lymphocytes suspicious for an inflammatory process. Permanent sections of the dura showed a diffusely infiltrating mass composed of mature lymphocytes peppered with large atypical lymphocytes. Immunohistochemical stains identified the small lymphocytes as T cells (CD3 and CD43) and the large atypical lymphocytes as B cells (CD20). Evidence of rearranged immunoglobulin heavy-chain genes demonstrated B-cell monoclonality. Differentiating between inflammatory and neoplastic lymphocytic masses of the dura obviously has important therapeutic and prognostic significance and may require immunohistochemical and molecular techniques.

Abstract Background: Mantle cell lymphoma (MCL) is characterized by t(11;14) which dysregulates cyclin D1 expression. Eμ-cyclinD1 transgenic mice, however, are healthy. Additional genetic events must be necessary for lymphomagenesis, and knowledge of these would enhance understanding and therapy of MCL. In addition, a mouse model of MCL would be helpful in drug development. Alterations in p53 have been described in MCL, often associated with the blastic variant. Objectives and Methods: To determine whether p53 and cyclin D1 can cooperate in lymphomagenesis, we cross bred Eμ-cyclinD1 transgenic mice (Bodrug et al EMBO J, 1996, courtesy of Alan Harris) with mice transgenic for mutant p53 (Jackson Labs, Jacks et al Curr Biol, 1994). Progeny mice were monitored for presence of the transgenes by PCR of tail vein DNA and observed for development of disease. Results: Of mice carrying both aberrant genes, 24 of 38 developed B cell lymphoma. Mice did not become visibly ill until at least 12 months of age, with median age at sacrifice 15.5 (range 12–23) months. The lymphoma was generally disseminated, involving spleen, liver, diffuse adenopathy and marrow with occasional extranodal sites. Histology varied between small and large cell, with some having a vaguely follicular growth pattern. T cell lymphomas occurred in 2 other mice, while 5 developed osteosarcoma (1 of these in a mouse that also had B cell lymphoma). The B cell lymphomas were clonal by Cμ-VH PCR. Cyclin D1 expression was documented by Western analysis. A cell line has also been developed from one of the B cell lymphomas and this line rapidly grows into disseminated lymphoma in syngeneic mice. These B cell lymphomas differ from the thymic T cell lymphomas seen in heterozygous p53 mutant mice that do not co-express cyclin D1. The latency period differs from cyclin D1 x myc double transgenic mice. Conclusions: This model demonstrates cooperation between p53 and cyclin D1 pathways in B cell lymphomagenesis and should prove useful in delineating how these signals interact. The cell line may prove useful in pre-clinical testing of new agents for MCL.

Abstract X-linked inhibitor of apoptosis protein (XIAP) is an important regulator of apoptosis which binds to and inhibits caspases-3, -7 and -9, blocking the caspase 9-mediated apoptosis pathway. This pathway is activated by p53 and DNA damage and may be an important determinant of responsiveness to chemotherapy. Apoptosis also plays a major role in the regulation of follicle center B-cell proliferation and BCL2-mediated inhibition of apoptosis is a key factor in B-cell lymphomagenesis. In this study we examined the expression of XIAP in 65 reactive and neoplastic lymphoid proliferations utilizing a monoclonal antibody to XIAP (#610763 BD Biosciences, San Jose, CA) and immunohistochemistry with avidin-biotin-complex immunoperoxidase technique on formalin-fixed, paraffin-embedded sections. In reactive lymph nodes and tonsils, expression of XIAP was limited to large noncleaved cells in follicle centers (5 of 6 cases). XIAP was absent in plasmacytoma (3 cases) and small lymphocytic lymphoma/chronic lymphocytic leukemia (1 case). XIAP was expressed in follicular lymphoma, predominantly in large noncleaved cells (6 of 9 cases) and in diffuse large B cell lymphoma (11 of 16 cases), including cases of T-cell/histiocyte-rich diffuse large B cell lymphoma (2 cases), primary mediastinal large B cell lymphoma (1 case), and posttransplantation diffuse large B cell lymphoma (1 case). XIAP was consistently expressed in Burkitt and Burkitt-like lymphoma (3 of 3 cases) and anaplastic large cell lymphoma (3 of 3 cases) and in one case of adult T cell leukemia/lymphoma. XIAP was variably expressed in marginal-zone B cell lymphoma, predominantly in large blasts (2 of 4 cases) and in mantle cell lymphoma (2 of 3 cases). XIAP was not detected in peripheral T cell lymphoma, unspecified (1 case), extranodal NK/T cell lymphoma, nasal type (1 case), precursor B cell lymphoblastic leukemia (1 case), or granulocytic sarcoma (1 case). XIAP was consistently expressed in the Reed-Sternberg and mononuclear Reed-Sternberg-variant cells of classical Hodgkin disease (9 of 9 cases) and the L+H Reed-Sternberg-variant cells of nodular lymphocyte predominance Hodgkin disease (3 of 3 cases). XIAP is expressed across a broad range of lymphoproliferative disorders, including classical and nodular lymphocyte predominance Hodgkin disease, diffuse large B cell lymphoma, follicular lymphoma, Burkitt lymphoma, marginal-zone and mantle cell lymphoma, and anaplastic large cell lymphoma. XIAP appears to be selectively expressed in the proliferating elements of these lymphomas. The possible prognostic and therapeutic significance of XIAP expression needs to be determined.

Abstract Patients with primary cutaneous lymphomas (PCLs) are treated with multiple therapeutic regimens, which may increase the risk of subsequent solid and haematological neoplasms. The aim of our study was to assess the incidence of other malignancies in our series of PCLs. From March 1994 to January 2007, 272 patients with PCLs (179 M, 93 F, median age 65 yr, range 14–88) were referred to our center for staging, treatment and follow-up. The clinical charts were reviewed to detect the incidence of malignancies occurred before or after the diagnosis of PCL or concomitantly. The series was composed by 228 patients (150 M, 78 F, median age 66 yrs) with T-cell lymphomas (202 Mycosis Fungoides/MF, 10 Sézary Syndrome/SS, 9 CD30+ PCL, 7 non MF/non CD30+ T cell PCL); 43 patients (28 M, 15 F, median age 60 yrs) with B-cell lymphomas (25 Follicular/FL, 14 marginal/MZL, 3 Leg-type, 1 Lymphoblastic) and one patient with CD4+/CD56+ hematodermic neoplasm. Chemotherapy was administered to 48 patients. During follow-up 12 patients died for the disease and 24 for other causes. A second tumor was observed in 41 patients (15%): 6 of them experienced more than one neoplasms: overall we observed 48 malignancies, 38 solid and 10 haematological. The other neoplasms appeared similarly before (20) and after (21) the diagnosis of PCL; in 7 cases they were diagnosed simultaneously. Solid tumours (17 preceding, 4 concurrent, 17 subsequent) were diagnosed in: skin (11), colon (5), lung (4), breast (3), CNS (3), bladder (2), liver (2), kidney (2), uterus (2), testis (1), prostate (1), stomach (1), thyroid (1). The haematological malignancies (3 preceding, 3 concurrent, 4 subsequent) were: B-cell lymphomas (4), acute myeloid leukemias (3), plasmocytoma (1), T-cell lymphoma (1), Hodgkin’s lymphoma (1). Among the six patients with more than one adjunctive neoplasms one patient had lung and kidney carcinoma preceding PCL; two patients a preceding carcinoma (skin and bladder, respectively) and subsequently a lung carcinoma; other two patients showed both a preceding and a concurrent neoplasm (skin and colon carcinoma, B-cell lymphoma and skin carcinoma, respectively). Finally a patient had a preceding skin carcinoma, a concurrent nodal Hodgkin’s lymphoma and a subsequent nodal B-cell lymphoma. So we have reported 48 other neoplasms in 41 patients within 272 PCLs (15%). The occurrence of the other malignancy was not related to the B/T phenotype of PCLs, as it was observed in 35/228 (15.4%) T-cell lymphomas (32 MF, 2 SS, 1 non MF/non CD30+ T cell lymphoma) and in 6/43 (14%) B-cell lymphomas (3 FL, 3 MZL; χ2 test: P=0.88). The interval of occurrence was longer for tumors preceding (median 60 mo.s, range 8–180) than for tumors following PCL (median 45, range 6–122). The administration of chemotherapy for PCL was not associated with an increased incidence of second neoplasm(χ2 test, P=0.77). Multicentric studies might help in elucidating the role of genetic and immunitary factors in the pathogenesis of multiple neoplasms in patients with PCLs.

AimTo report the first case of a Richter syndrome where small lymphocytic lymphoma (SLL) progressed to a CD3+ diffuse large B-cell lymphoma (DLBCL).MethodsMacrodissection of small and large cell lymphomatous components was performed. This was followed by flow cytometric analysis along with molecular B-cell immunoglobulin (heavy and light chains) and T-cell receptor (γ and β chains) gene rearrangement studies to investigate a clonal relationship between the components.ResultsThe immunophenotypic profile was similar between small and large cell components of the lymphoma by flow cytometry. Furthermore, shared clonal peaks were observed between both components based on molecular B-cell and T-cell receptor gene rearrangement studies, confirming a clonal relationship.ConclusionsChronic lymphocytic leukaemia/SLL may rarely undergo Richter transformation to a DLBCL demonstrating lineage infidelity. This is a potentially important diagnostic pitfall and such cases should not be confused with a de novo T-cell lymphoma.

17566 Background: The clinicopathologic characteristics of malignant lymphomas vary according to geography. The aim of this study was to determine the relative frequency of cutaneous lymphomas and to examine the clinical relevance of the new WHO/EORTC classification in Peruvian cases of cutaneous lymphoma. Methods: We conducted a clinicopathologic retrospective study of a collection of 68 primary cutaneous lymphomas, diagnosed from 1997 to 2004 in a National General Hospital. The clinical records, haematoxylin & eosin-stained slides and immunohistochemical stains from 67 patients with malignant lymphomas of the skin were reviewed. HTLV-1 serology was made using ELISA and Western Blot methods. The statistical method was descriptive and survival was calculated using the Kaplan-Meier method. Results: Mean age at presentation was 62 years and the female/male ratio 1.5:1. T cell lymphomas were 88.6% and 11.4% were B-cell lymphomas. The most frequent cutaneous lymphoma was mycosis fungoides (MF) 30/67 (44.7%), Adult T-cell leukemia/lymphoma (ATLL) 13/67 (19.4%), unspecified peripheral T-cell lymphoma 4/67 (6%), lymphomatoid papulosis 2/67 (3%), leg-type diffuse large B-cell lymphoma 2/67 (3%), diffuse large B-cell lymphoma 2/67 (3%), subcutaneous panniculitis-like T-cell lymphoma 2/67 (3%), anaplastic large cell lymphoma 1/67 (1.4%), Sézary síndrome 1/67 (1.4%), nasal type extranodal NK/T-cell lymphoma 1/67 (1.4%), marginal zone B-cell lymphoma 1/67 (1.4%), follicle center lymphoma 1/67 (1.4%), intravascular lymphoma 1/67 (1.4%) and unclassifiable 5/67 ( 7.4%). Clinical stages of MF were: 60% stage I; 30% stage II; 3% stage III and 7% stage IV. 5-year survival was 77%. In ATLL group, 3 had smouldering type and 10 had cutaneous type. 5-year survival was 18%. Conclusions: In this retrospective analysis, cutaneous T cell lymphomas were prevalent; both MF and ATLL had the most frequency among primary cutaneous lymphomas in our hospital. ATLL had a poor 5-year survival. No significant financial relationships to disclose.
