BACKGROUND: Primary central nervous system (CNS) diffuse large B-cell lymphoma (DLBCL) is a rare intracranial tumor, defined as DLBCL arising from the brain, spinal cord, leptomeninges and eye, with an overall annual incidence of 5 cases per million. The primary CNS anaplastic variant of DLBCL (A-DLBCL) is even less common; to our knowledge, there are only two other case reports in the literature. The aim of this report is to present rare cases of primary CNS A-DLBCL and study their clinicopathologic and genetic features...

PURPOSE: This study assessed the performance of four different methods for the estimation of metabolic tumour volume (MTV) in primary mediastinal B cell lymphoma (PMBCL). METHOD: MTV was estimated using either a region growing automatic software program (RG) or a fixed threshold (FT) segmentation algorithm with the three most common cut-offs proposed in the literature (i.e., 25% and 41% of the SUVmax and SUV value ≥2.5). We compared these four methods using phantoms that simulated different set-ups of the main imaging characteristics of PMBCL (volume, shape, 18-FDG uptake and intra-lesion distribution) and assessed their performance in 103 PMBCL patients enrolled in the International Extranodal Lymphoma Study Group-26 (IELSG-26) study...

Splenectomy in addition to immunotherapy with rituximab can provide quick and sometimes durable disease control in patients with splenic marginal zone lymphoma (SMZL). However, systemic chemotherapy is ultimately required in many cases. The BRISMA (Bendamustine-rituximab as first-line treatment of splenic marginal zone lymphoma)/IELSG (International Extranodal Lymphoma Study Group)36 trial is an open-label, single arm phase II study designed by the IELSG in cooperation with the Fondazione Italiana Linfomi and the lymphoma Study Association according to Simon's two-stage method...

An important unmet need in the management of primary mediastinal B-cell lymphoma (PMBCL) is to identify the patients for whom first-line therapy will fail to intervene before the lymphoma becomes refractory. High heterogeneity of intratumoral 18 F-fluorodeoxyglucose (18FDG) uptake distribution on positron emission tomography/computed tomography (PET/CT) scans has been suggested as a possible marker of chemoresistance in solid tumors. In the present study, we investigated the prognostic value of metabolic heterogeneity (MH) in 103 patients with PMBCL prospectively enrolled in the International Extranodal Lymphoma Study Group (IELSG) 26 study, aimed at clarifying the role of PET in this lymphoma subtype...

Context: Primary central nervous system lymphoma (PCNSL) is a variant of extranodal lymphoma, accounting for 4% of primary central nervous system tumors. PCNSL was more common in immunocompetent individuals. International Extranodal Lymphoma Study Group (IELSG) scoring was used for prognostication. High-dose methotrexate regimens along with radiotherapy improved outcomes in PCNSL. Aims: The aim of this study is to analyze the clinical and pathological features, progression-free survival (PFS), and overall survival (OS) in patients with PCNSL...

BACKGROUND: The International Extranodal Lymphoma Study Group-32 (IELSG32) trial is an international randomised phase 2 study that addresses two key clinical questions in the treatment of patients with newly diagnosed primary CNS lymphoma. Results of the first randomisation have demonstrated that methotrexate, cytarabine, thiotepa, and rituximab (called the MATRix regimen) is the induction combination associated with significantly better outcome compared with the other induction combinations tested...

There are no widely accepted prognostic indices for extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT). This study aimed to develop and validate a specific prognostic tool to personalize and optimize treatment of patients with MALT lymphoma. A prognostic index was built by Cox regression (stepwise selection) using data from 401 patients enrolled in the international randomized International Extranodal Lymphoma Study Group 19 (IELSG-19) trial (NCT 00210353). A validation set, including 633 patients, was obtained by merging 3 independent cohorts of MALT lymphoma patients...

The International Extranodal Lymphoma Study Group-26 study evaluated the prognostic role of 18-fluorodeoxyglucose positron-emission tomography (PET) in primary mediastinal large B-cell lymphoma. We assessed quantitative PET parameters at diagnosis and post-treatment in 100 patients. The end-of-therapy total lesion glycolysis (TLG) was the best individual outcome predictor, but the combination of baseline TLG and end-of-therapy visual analysis with Deauville Score (DS) showed a better positive predictive value...

Purpose There is no consensus on the optimal systemic treatment of patients with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue. The IELSG-19 phase III study, to our knowledge, was the first such study to address the question of first-line treatment in a randomized trial. Patients and Methods Eligible patients were initially randomly assigned (1:1 ratio) to receive either chlorambucil monotherapy (6 mg/m2 /d orally on weeks 1 to 6, 9 to 10, 13 to 14, 17 to 18, and 21 to 22) or a combination of chlorambucil (same schedule as above) and rituximab (375 mg/m2 intravenously on day 1 of weeks 1, 2, 3, 4, 9, 13, 17, and 21)...

REVIEW
Franco Cavalli, Luca Ceriani, Emanuele Zucca
Primary mediastinal large B-cell lymphoma (PMLBCL) is recognized as a distinct disease entity. Treatment outcomes appear better than in other diffuse large B-cell lymphoma (DLBCL) types, partly because of their earlier stage at presentation and the younger age of most patients. If initial treatment fails, however, the results of salvage chemotherapy and myeloablative treatment are poor. The need to avoid relapses after initial therapy has led to controversy over the extent of front-line therapy, particularly whether consolidation radiotherapy to the mediastinum is always required and whether the 18-fluorodeoxyglucose ((18)F-FDG) uptake detected by PET-CT scan can be used to determine its requirements...

BACKGROUND: Standard treatment for patients with primary CNS lymphoma remains to be defined. Active therapies are often associated with increased risk of haematological or neurological toxicity. In this trial, we addressed the tolerability and efficacy of adding rituximab with or without thiotepa to methotrexate-cytarabine combination therapy (the MATRix regimen), followed by a second randomisation comparing consolidation with whole-brain radiotherapy or autologous stem cell transplantation in patients with primary CNS lymphoma...

Upfront autologous stem cell transplantation (ASCT) has shown favourable outcome in patients with primary central nervous system lymphoma (PCNSL), but the role of risk-adapted upfront ASCT consolidation has not been evaluated in PCNSL. As PCNSL patients with the International Extranodal Lymphoma Study Group (IELSG) prognostic score ≥2 or those who did not achieve complete response after two courses of induction chemotherapy (non-CR1) have shown inferior outcomes, we retrospectively analysed the role of upfront ASCT in 66 high-risk (IELSG ≥2 and/or non-CR1) younger (age <65 years) immunocompetent PCNSL patients who achieved at least partial response after initial high-dose methotrexate-based chemotherapy...

We aimed to compare the characteristics and outcome of patients treated within the multi-centre German Primary CNS Lymphoma Study Group 1 trial (G-PCNSL-SG-1; TRIAL group) and patients treated outside this clinical trial ("real-life" setting, R-LIFE group). Therefore, we conducted a retrospective single-centre study in order to analyse all patients with newly diagnosed primary CNS lymphoma (PCNSL) treated consecutively in our institution between November 2000 and June 2015. Altogether, 86 patients were analysed (median 68 years)...

COMMENT
Michel Meignan
In this issue of Blood, Ceriani et al introduce, in primary mediastinal B-cell lymphoma (PMBCL), a new prognostic factor measured on pretreatment 18F-fluorodeoxyglucose (18FDG)-positron emission tomography (PET)/computed tomography (CT): the total lesion glycolysis (TLG), which is an index of the glucose uptake by the total tumor burden. This paper is part of the International Extranodal Lymphoma Study Group (IELSG) 26 prospective study designed to evaluate the role of PET in the treatment of PMBCL.

Primary lymphoma of the lung is a rare entity. Clinical features, optimal treatment, role of surgery and outcomes are not well defined, and the follow-up is variable in published data. Clinical data of 205 patients who were confirmed to have bronchus mucosa-associated lymphoid tissue lymphoma from December 1986 to December 2011 in 17 different centres worldwide were evaluated. Fifty-five per cent of the patients were female. The median age at diagnosis was 62 (range 28-88) years. Only 9% had a history of exposure to toxic substances, while about 45% of the patients had a history of smoking...
