Epstein-Barr virus-positive diffuse large B-cell lymphoma (EBV+DLBCL) is an aggressive malignancy that is largely resistant to current therapeutic regimens, and is an attractive target for immune-based therapies. Anti-programmed death-1 (PD-1) antibodies showed encouraging anti-tumor effects in both preclinical models and advanced solid and hematological malignancies, but its efficacy against E...
PURPOSE Epstein-Barr virus-positive (EBV(+)) diffuse large B-cell lymphoma (DLBCL) of the elderly is a variant of DLBCL with worse outcome that occurs most often in East-Asian countries and is uncommon in the Western hemisphere. We studied the largest cohort of EBV(+) DLBCL, independent of age, treated with rituximab combined with CHOP (R-CHOP) in developed Western countries. EXPERIMENTAL DES...
INTRODUCTION Diffuse large B-cell lymphomas (DLBCL) can be divided into germinal centre (GC-DLBCL) and post germinal centre (post GC-DLBCL) groups by applying immunohistochemical antibodies. As these subgroups respond differently to chemotherapy, it is possible at diagnosis to select a poor prognostic subgroup for aggressive treatment. OBJECTIVE To determine the frequencies of GC-DLBCL and po...
BACKGROUND Several potential risk factors have been identified for diffuse large B-cell lymphoma (DLBCL); however, epidemiological studies investigating the association between these risk factors and DLBCL have yielded inconsistent results. OBJECTIVES To investigate potential medical, lifestyle, and environmental risk factors of DLBCL in Shanghai, China through a hospital-based case-control s...
The prognostic implications of miR-21, miR-17-92 and miR-155 were evaluated in diffuse large B-cell lymphoma (DLBCL) patients, and novel mechanism by which miR-21 contributes to the oncogenesis of DLBCL by regulating FOXO1 and PI3K/AKT/mTOR pathway was investigated. The expressions of miR-21, miR-17-92 and miR-155 measured by quantitative reverse-transcription-PCR were significantly up-regulate...
Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma in adults. DLBCL exhibits highly aggressive and systemic progression into multiple tissues in patients, particularly in lymph nodes. Whole-body 18F-fluodeoxyglucose positron emission tomography ([18F]FDG-PET) imaging has an essential role in diagnosing DLBCL in the clinic; however, [18F]FDG-PET often faces difficulty in different...
Diffuse large B cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma in all countries and all age groups. DLBCL is potentially curable, and the outcome of patients with DLBCL has completely changed with the introduction of therapy involving the monoclonal antibody rituximab in combination with chemotherapy. Nonetheless, relapse is detected after treatment with rituximab, cyc...
The presence of diffuse large B-cell lymphoma (DLBCL) with a concomitant unsuspected population of B cells with chronic lymphoid leukemia (CLL) phenotype is very rare with no antecedent history of CLL. This may represent cases of de novo Richter’s transformation or the coexistence of two neoplasms [1]. In cases where the monoclonal B-cell population does not exceed 5x109/L, this may represent D...
The adaptor protein MYD88 is critical for relaying activation of Toll-like receptor signaling to NF-κB activation. MYD88 mutations, particularly the p.L265P mutation, have been described in numerous distinct B-cell malignancies, including diffuse large B-cell lymphoma (DLBCL). Twenty-nine percent of activated B-cell-type DLBCL (ABC-DLBCL), which is characterized by constitutive activation of th...
FOXP2 shares partially overlapping normal tissue expression and functionality with FOXP1; an established diffuse large B-cell lymphoma (DLBCL) oncogene and marker of poor prognosis. FOXP2 is expressed in the plasma cell malignancy multiple myeloma but has not been studied in DLBCL, where a poor prognosis activated B-cell (ABC)-like subtype display partially blocked plasma cell differentiation. ...
