Occupation and Risk of Non-Hodgkin Lymphoma and Its Subtypes: A Pooled Analysis from the InterLymph Consortium
2016
Background: Various occupations have been associated with an elevated risk of non-Hodgkin lymphoma (NHL), but results have been inconsistent across studies. Objectives: We investigated occupational risk of NHL and of four common NHL subtypes with particular focus on occupations of a priori interest. Methods: We conducted a pooled analysis of 10,046 cases and 12,025 controls from 10 NHL studies participating in the InterLymph Consortium. We harmonized the occupational coding using the 1968 International Standard Classification of Occupations (ISCO-1968) and grouped occupations previously associated with NHL into 25 a priori groups. Odds ratios (ORs) adjusted for center, age, and sex were det…
Non-Hodgkin Lymphoma, Body Mass Index, and Cytokine Polymorphisms: A Pooled Analysis from the InterLymph Consortium.
2015
Abstract Background: Excess adiposity has been associated with lymphomagenesis, possibly mediated by increased cytokine production causing a chronic inflammatory state. The relationship between obesity, cytokine polymorphisms, and selected mature B-cell neoplasms is reported. Method: Data on 4,979 cases and 4,752 controls from nine American/European studies from the InterLymph consortium (1988–2008) were pooled. For diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), joint associations of body mass index (from self-reported height and weight) and 12 polymorphisms in cytokines IL1A (rs1800587), IL1B (rs16944,…
Rituximab in vivo purging is safe and effective in combination with CD34-positive selected autologous stem cell transplantation for salvage therapy i…
2002
The purpose of this study was to evaluate feasibility and efficacy of Rituximab included into a sequential salvage protocol for CD20(+) B-NHL in relapse or induction failure. Twenty-seven patients with CD20(+) B-NHL in relapse or induction failure received Rituximab combined with DexaBEAM (R-DexaBEAM) for stem cell mobilization. Additional ex vivo selection of CD34-positive cells was performed using the CliniMacs device. Two doses of Rituximab were included in the high-dose therapy regimen (HDT). R-DexaBEAM was well tolerated and 26 of 27 patients mobilized sufficient numbers of CD34(+) blood stem cells. Application of R-DexaBEAM resulted in significant depletion of peripheral B cells. No t…
Treatment for patients with relapsed/refractory mantle cell lymphoma: European-based recommendations
2017
International audience; Patients with mantle cell lymphoma (MCL) usually respond to initial combination chemotherapy, but the disease inevitably relapses and often follows an aggressive course. Here, clinical study results published since 2008 for patients with relapsed/refractory MCL were reviewed to compare available evidence for treatment guidance. Most trials identified were non-randomized, phase II studies performed at a limited number of sites, and many evaluated MCL as one of multiple non-Hodgkin lymphoma subtypes. Additional randomized, comparative trials are needed. Treatment selection generally depends on patient need, age and fitness, time of relapse, and line of therapy. Combina…
Durability of complete response after blinatumomab therapy for relapsed/refractory diffuse large B-cell lymphoma
2020
Despite advances in standards of care, the prognosis of relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) remains poor. In these patients, 50–74% fail to respond to next line therapy,...
Abstract B072: Phase Ib trial of the RNActive cancer vaccine BI 1361849 (CV9202) and local radiotherapy in patients with stage IV non-small cell lung…
2016
Abstract Background: Preclinical studies demonstrated that local radiotherapy (RT) acts synergistically with RNActive mRNA vaccines to enhance anti-tumor effects and increase tumor-infiltrating lymphocytes. BI 1361849 is a therapeutic vaccine comprising optimized mRNA constituents encoding six NSCLC-associated antigens. Interim data of a phase Ib study, employing local RT to increase the immune mediated tumor control by BI 1361849, have been previously published (J Clin Oncol 34, 2016, suppl; abstr e20627). Here we report results of immune response analyses as well as updated safety and efficacy data. Methods: Patients (pts) with stage IV NSCLC were enrolled in three cohorts based on histol…

Glioblastoma (GBM) remains an unmet need in Medical Oncology considering its poor prognosis and the lack of advances in therapeutics in more than one decade.1 Despite the initial enthusiasm, the development of immunotherapy in GBM has proved to be challenging, with a disappointing negative phase III clinical trial.2 Some of the phenotypic hallmarks of GBM make immunotherapy difficult. Its relatively low mutational load, its immunologically ‘cold’ microenvironment with scarce infiltrating immune effector cells, a dominant myeloid compartment composed by microglia and myeloid-derived suppressor cells and a strong immunosuppression, both local, mediated by immunosuppressive regulatory T cells …
Prognostic role of immune checkpoint-related genes in resectable lung adenocarcinomas.
2014
11085 Background: Immune checkpoints blockade has demonstrated promising clinical results in NSCLC patients. In this study we have investigated the prognostic role of immune checkpoint markers (CTLA4, PD1 and PDL1) in resectable lung adenocarcinoma (ADC). Methods: RNA was isolated from fresh-frozen lung specimens (tumor and normal lung) from resectable ADC patients (n=92). RT-PCR was performed to analyze the expression of CTLA4, PD1 and PDL1 by the use of hydrolysis probes. Relative gene expression was assessed by Pfaffl formula and normalized by CDKN1B and ACTB as endogenous genes (selected by geNorm algorithm). Statistical analyses were considered significant at p<0.05. Results: Patient’s…
Abstract 4330: Immune checkpoint expression score is an independent prognostic biomarker in resectable non-small cell lung cancer
2015
Abstract BACKGROUND Immune checkpoints blockade, which activate antitumor immunity, has demonstrated promising clinical results in NSCLC. In this study we have investigated the prognostic role of immune checkpoint expression markers and its correlation with immune-cells infiltration and clinico-pathological characteristics in a cohort of resectable NSCLC patients. MATERIAL AND METHODS RNA was isolated from fresh-frozen lung specimens (tumor and normal lung) (n = 178). RTqPCR was performed to analyze the expression of CTLA-4, PD-1 and PD-L1 by the use of hydrolysis probes. Relative gene expression was assessed by Pfaffl formula and normalized by the use of CDKN1B, GUS and ACTB as endogenous …
Durability of complete response after blinatumomab therapy for refractory/relapsed aggressive B-cell non-Hodgkin lymphoma.
2019
e19041 Background: Achieving durable response in patients (pts) with relapsed/refractory (R/R) aggressive B-cell lymphoma (B-NHL) is challenging. Blinatumomab, a bispecific T-cell engager (BiTE) immunotherapy targeting CD19-expressing cancer cells, has shown promising efficacy in pts with R/R aggressive B-NHL. We report the durability of complete response (DOCR) in pts treated with blinatumomab. Methods: The DOCR in pts with R/R aggressive B-NHL responding to blinatumomab was assessed using data from two phase 2 studies (study 1 [N = 25], NCT01741792; study 2 [N = 41], NCT02910063) in pts with R/R aggressive B-NHL. CR was assessed using Cheson (study 1) and Lugano (study 2) criteria. Time-…
