INTRODUCTION: This pooled analysis study aimed to reveal the prognostic relevance of microRNAs (miRNAs) in patients with diffuse large B-cell lymphoma (DLBCL). MATERIALS AND METHODS: We examined the impact of miRNAs on clinical outcome. Eligible studies were identified and quality assessed using multiple search strategies. Data were extracted from included studies which correlated survival with expression of miRNAs (serum or tissue). RESULTS: We pooled proper studies, and combined the hazard ratios with 95% confidence intervals to estimate strength of the correlations...

Secondary central nervous system (CNS) relapse is a serious and fatal complication of diffuse large B cell lymphoma (DLBCL). Data on secondary CNS (SCNS) relapse were mostly obtained from western countries with limited data from developing countries. We analyzed the data of 2034 newly diagnosed DLBCL patients enrolled into the multi-center registry under Thai Lymphoma Study Group from setting. The incidence, September 2006 to December 2013 to represent outcome from a resource limited pattern, management, and outcome of SCNS relapse were described...

Histone methylation and demethylation regulates B-cell development, and their deregulation correlates with tumor chemoresistance in diffuse large B-cell lymphoma, limiting curative rates. Since histone methylation status correlates with disease aggressiveness and relapse, we investigated the therapeutic potential of inhibiting histone 3 Lys27 demethylase KDM6B, in-vitro, using the small molecule inhibitor GSK-J4. KDM6B is overexpressed in the DLBCL germinal center B-cell subtype, and higher KDM6B levels are associated with worse survival in DLBCL patients treated with R-CHOP...

The addition of rituximab has improved outcomes in diffuse large B-cell lymphoma (DLBCL), however, there remains limited information on the impact of rituximab in those with testicular involvement. All patients with diffuse large cell lymphoma and testicular involvement treated with curative intent were identified in the British Columbia Cancer Agency Lymphoid Cancer Database. In total, 134 patients diagnosed between 1982 and 2015 with diffuse large cell lymphoma involving the testis were identified: 61 received CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone)-like chemotherapy and 73 received CHOP plus rituximab (R-CHOP)...

Little is known on the phylogenetic relationship between diagnostic and relapse clones of Diffuse Large B-Cell Lymphoma (DLBCL). We applied High Throughput Sequencing (HTS) of the VDJ locus of Immunoglobulin Heavy chain (IGHV) on fourteen DLBCL patients with serial samples, including tumor biopsies and/or peripheral blood mononuclear cells (PBMC). Phylogenetic data were consolidated with targeted sequencing and cytogenetics. Phylogeny clearly showed that DLBCL relapse could occur according either an early or a late divergent mode...

Diffuse large B-cell lymphomas with aberrations in MYC, BCL2 and/or BCL6 by genetic alterations or protein expression represent a group of high grade B-cell lymphomas with inferior outcomes when treated with standard RCHOP chemotherapy. As a result, intensified induction regimens have been suggested in an effort to improve outcomes. Conclusions to date have largely been drawn from retrospective data although prospective data is slowly starting to emerge. Chemoimmunotherapy refractoriness is problematic and relapse rates are high...

Central nervous system involvement remains a challenging issue in the treatment of patients with diffuse large B-cell lymphoma. We conducted a prospective cohort study with newly diagnosed diffuse large B-cell lymphoma patients receiving rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone to identify incidence and risk factors for central nervous system involvement. Among 595 patients, 279 patients received pre-treatment central nervous system evaluation, and 14 patients had central nervous system involvement at diagnosis (2...

Diffuse large B cell lymphoma (DLBCL) is a common B cell malignancy. Complete remission can be achieved in most patients by conventional treatment with rituximab and chemotherapy. However, a subset of remission individuals will develop a relapsed disease for obscure reasons. CD4(+)Foxp3(-)IL-10(+) cell (Tr1) is a novel cell subtype with the capacity to suppress pro-inflammatory responses, but has not been extensively studied in most tumors. In this study, we investigated the potential role of Tr1 cells in DLBCL...

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of mature B-cell lymphoma. While the majority of patients are cured with immunochemotherapy incorporating the anti-CD20 monoclonal antibody rituximab (R-CHOP), relapsed and refractory patients still have a dismal prognosis. DLBCL subtypes including an aggressive activated B-cell-like (ABC) and a more favorable prognosis germinal center-like (GCB) DLBCL have been identified by gene expression profiling and are characterized by distinct genetic abnormalities and oncogenic pathways...

BACKGROUND: For patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), autologous hematopoietic cell transplantation (auto-HCT) is commonly used. After auto-HCT, DLBCL patients are often monitored with surveillance imaging. However, there is little evidence to support this practice. PATIENTS AND METHODS: We performed a multicenter retrospective study of DLBCL patients who underwent auto-HCT (n = 160), who experienced complete remission after transplantation, and who then underwent surveillance imaging...

Using SEER-Medicare linked data we identified elderly patients diagnosed with diffuse large B-cell lymphoma (DLBCL) between January 2000 and December 2007 who received second-line outpatient chemotherapy for relapsed or refractory disease. Second-line regimens were classified into three mutually exclusive groups: aggressive, conventional, and palliative. Of the 632 (426 relapsed, 206 refractory) patients in the cohort, 27.8% received aggressive second-line therapy, 39.1% received conventional therapy, and 33...

During treatment for malignant lymphoma, cytopenia can develop for several reasons. In the treatment of cytopenia, various possibilities should be considered because inadequate treatment causes exacerbation of cytopenia and can lead to fatal conditions, such as infection and bleeding. Herein, we describe immune pancytopenia 3 months after the last exposure to chemotherapy in a patient with diffuse large B-cell lymphoma (DLBCL). She suffered from severe pancytopenia after two courses of rituximab and bendamustine therapy for a second relapse of DLBCL...

Primary cardiac lymphoma (PCL) is a rare extranodal lymphoma that involves only the heart and/or pericardium. Primary cardiac lymphoma is much less common in immunocompetent patients compared with those who are immunosuppressed. Patients with PCL have variable clinical manifestations that may lead to misdiagnosis and delay in treatment. Modern radiologic imaging now allows for earlier detection of these tumors. This study describes the clinical, histologic/cytologic, immunophenotypic, and molecular genetic findings for 3 immunocompetent patients with primary cardiac diffuse large B-cell lymphoma...

In the CORAL study, 255 chemosensitive relapses with diffuse large B-cell lymphoma (DLBCL) were consolidated with autologous stem cell transplantation (ASCT), and 75 of them relapsed thereafter. The median time between ASCT and progression was 7.1 months. The median age was 56.1 years; tertiary International Prognosis Index (tIPI) observed at relapse was 0-2 in 71.6% of the patients and >2 in 28.4%. The overall response rate to third-line chemotherapy was 44%. The median overall survival (OS) was 10.0 months (median follow-up: 32...

PURPOSE: Pinatuzumab vedotin is an antibody-drug conjugate with the potent antimicrotubule agent monomethyl auristatin E (MMAE) conjugated to an anti-CD22 antibody via a protease-cleavable linker. This Phase I study determined its recommended Phase II dose (RP2D) and evaluated its safety, tolerability, and anti-tumor activity alone and with rituximab in relapsed/refractory (r/r) non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL). EXPERIMENTAL DESIGN: Patients received escalating doses of pinatuzumab vedotin every 21 days...

The CD30 antigen is strongly expressed on neoplastic cells in classical Hodgkin lymphoma (HL), anaplastic large cell lymphoma (ALCL) and other hematologic malignancies (such as DLBCL and cutaneous TCL), while is almost undetectable on healthy tissues, representing an ideal immunotherapeutic target. Since unconjugated anti-CD30 antibody (SGN-30) demonstrated limited clinical activity, researchers' effort aimed to create an antibody-drug conjugate (ADC), leading to discovery of SGN-35 (brentuximab vedotin), in which an anti-CD30 antibody is linked to the antimitotic agent monomethyl auristatin E (MMAE)...

Diffuse large B-cell lymphoma (DLBCL) is a subtype of non-Hodgkin lymphoma occurring in various sites, but rarely involving the ureters. Primary DLBCL is a rare entity. Imaging studies in a 82-year-old male patient revealed left hydronephrosis and an area of nodular soft tissue density in the upper ureteral wall. On enhanced computed tomography scans, the lesion exhibited early enhancement. As the lesion was considered to be malignant, a left nephroureterectomy was performed for the purpose of pathological diagnosis...
