OBJECTIVE: : Diffuse Large B Cell Lymphoma (DLBCL) is a heterogeneous group of tumors with different biological and clinical characteristics that have diverse clinical outcomes and response to therapy. Stromal-1 signature of tumor microenvironment of DLBCL represents extracellular matrix deposition and histiocytic infiltrate, whereas stromal-2 represents angiogenesis that could affect tumor progression. METHODS: : The aim of the present study is to assess the significance of stromal-1 signature using SPARC-1 and stromal-2 signature using CD31 expression and then finally to construct biologic prognostic model (BPM) in 60 cases of DLBCL via immunohistochemistry...

The response evaluation criteria in patients with Hodgkin Lymphoma (HL) were designed for the assessment of chemotherapy and targeted molecular agents. We investigated the accuracy of 3-month-(18)F-FDG-PET/CT for the identification of HL patients (pts) responding to immune-checkpoint blockade by Anti-Programmed Death 1 antibodies (anti-PD1). We also reported the frequency of new immune patterns of response and progression. Methods: Retrospectively, we recruited consecutive HL patients treated by anti-PD1 (Pembrolizumab or Nivolumab) at Gustave Roussy, Villejuif, France, from 2013-2015...

Most commonly, histologic transformation (HT) from follicular lymphoma (FL) manifests as a diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS). Less frequently, HT may result in a high-grade B-cell lymphoma (HGBL) with MYC and B-cell lymphoma protein 2 (BCL2) and/or BCL6 gene rearrangements, also known as "double-hit" or "triple-hit" lymphomas. In the 2016 revision of the World Health Organization (WHO) classification of lymphoid neoplasms, the category B-cell lymphoma, unclassifiable was eliminated due to its vague criteria and limiting diagnostic benefit...

Splenic marginal zone lymphoma (SMZL) is a low-grade B-cell non-Hodgkin's lymphoma characterized by massive splenomegaly, moderate lymphocytosis with or without villous lymphocytes, rare involvement of peripheral lymph nodes and indolent clinical course. As a rare disease, with no randomized prospective trials, there is no standard of care for SMZL so far. Splenectomy has been done for many years as an attempt to control disease, but nowadays it has not been encouraged as first line because of new advances in therapy as rituximab, that are as effective with minimal toxicity...

Introduction. Splenic tumor is usually found as an incidental finding on CT of abdomen. Traditionally, ultrasound (US) or computed tomography (CT) guided biopsies were employed for the purpose of sampling; however they have been reported to have a complication rate of 5.3%. Endoscopic ultrasound-fine needle aspiration (EUS-FNA) has been recently utilized for the purpose of sampling splenic tumors. In literature there are 7 reported instances where splenic lymphoma was diagnosed using EUS-FNA. We present a case of follicular B cell lymphoma of the spleen diagnosed using EUS-FNA...

Splenic marginal zone lymphoma (SMZL) is a rare B-cell lymphoma, well defined according to the 2016 WHO classification of tumors of the hematopoietic tissue, which can raise diagnostic problems. We report the case of a 72-year old patient, hospitalised for exploration of a massive splenomegaly confirmed by computed tomography (CT). Laboratory tests were normal. The patient underwent splenectomy. Microscopic examination of the surgical specimen showed widespread lymphomatous proliferation in small cells associated with CD20 marker...

Nodular lymphocyte Hodgkin lymphoma (NLPHL) is a rare disease for which the optimal therapy is unknown. We hypothesized R-CHOP could decrease rates of relapse and transformation. We retrospectively reviewed patients with NLPHL diagnosed between 1995 and 2015 confirmed by central pathologic review. Fifty-nine had sufficient treatment and follow-up data for analysis. We described progression-free (PFS), overall survival (OS) and histologic transformation according to treatment strategy and explorede prognostic factors for PFS and OS...

Splenic infiltration is often seen in diffuse large B-cell lymphoma (DLBCL). However, primary splenic DLBCL is rare and studies on its clinicopathological features are limited. We assessed 66 cases of primary splenic DLBCL and 309 control DLBCL, not otherwise specified. Hepatitis C virus antibody prevalence, B symptoms, poor performance status and CD5 positivity differed significantly between the primary splenic DLBCL and control DLBCL groups. Primary splenic DLBCL cases were classified histopathologically into two groups [white pulp pattern (n = 46), red pulp pattern (n = 20)]...

The commonly seen primary malignant neoplasms of the spleen are angiosarcoma and lymphoma. We present a case of serous cystadenocarcinoma of the spleen. It was presumed to be originated from dropped nonmalignant ovarian tissue, which was accidentally implanted to the splenic surface during hysterectomy and bilateral salpingooophorectomies for torsion of right fallopian tube 9 and half years ago and transformed into serous cystadenocarcinoma later. Computed tomography demonstrated a multilocular predominantly cystic tumor with internal soft tissue components in the spleen...

INTRODUCTION: Splenectomy is helpful in the management of selected patients with Hodgkin's lymphoma (HL), but in some cases this procedure is accompanied by a greater morbidity and mortality mainly due to sepsis. This is the first published case of subtotal splenectomy preserving the inferior splenic pole without the maintenance of the splenic vascular pedicle. PRESENTATION OF CASE: A 53-year-old man with HL refractory to chemo and radiotherapy associated to a very large spleen was successfully treated with subtotal splenectomy, preserving the inferior splenic pole supplied only by the left gastroepiploic and inferior splenic pole vessels...

To obtain insight into the ontogeny of mantle cell lymphoma (MCL), we assessed 206 patients from a morphological, immunohistochemical, and immunogenetic perspective. Our series included nodal (n = 151), extranodal (n = 28), and primary splenic (n = 27) MCL cases. Skewing of the immunoglobulin heavy variable (IGHV) gene repertoire was noted, with only four IGHV genes accounting for 46% of cases and approximately 70% of cases (107/154) bearing an imprint of somatic hypermutation (SHM) ranging from minimal to pronounced...

Splenic marginal zone lymphoma (SMZL) is an uncommon indolent B-cell non-Hodgkin's lymphoma. The clinical features of SMZL are splenomegaly, lymphocytosis and cytopenia in peripheral blood. Immunopheno-typically, the neoplastic cells are typically positive for CD45, CD20, CD79a, PAX5, IgD, BCL-2. The previous common used treatment is splenectomy and chemotherapy. Nowadays, rituximab-based chemotherapy regimens has improved the curative effect dramaticlly. IFN-α with or without ribavirin can be used to treat the patients with HCV infection...

Myeloid-derived suppressor cells (MDSCs) accumulate in tumor-bearing hosts and play a key role in the suppression of the innate and adaptive immunity. Chemotherapeutic strategies have been developed to deplete or deactivate MDSCs in different tumor models. The pyrimidine analog, 5-fluorouracil (5-FU) is found to reduce the tumor size by depleting MDSCs. Here, we asked whether the purine analog, fludarabine (Flu), could exert similar effects. Employing a lymphoma model, we demonstrated that in mice with advanced tumors (where MDSC-induced suppression was present), treatment with a single low-dose Flu (25, 50, 100mg/kg) elevated the numbers of splenic MDSCs and serum arginase activity, and simultaneously, increased the tumor growth (only the highest dose)...
