DNA repair genes are selectively mutated in diffuse large B cell lymphomas

DNA repair mechanisms are fundamental for B cell development, which relies on the somatic diversification of the immunoglobulin genes by V(D)J recombination, somatic hypermutation, and class switch recombination. Their failure is postulated to promote genomic instability and malignant transformation in B cells. By performing targeted sequencing of 73 key DNA repair genes in 29 B cell lymphoma s...

Lenalidomide in Diffuse Large B-Cell Lymphomas

Diffuse Large B-cell Lymphomas (DLBCL) are the most frequent Non-Hodgkin Lymphomas (NHL). The addition of Rituximab to the standard chemotherapy CHOP improved the outcome in this patients, but so far 40% of patients experienced relapse or progressive disease. Lenalidomide, an immunomodulatory agent, had direct tumoricidal and antiangiogenetic actions on tumor cells and was able to modulate tumo...

BCL2 Family Related Genes Expression and Chemotherapy Response in Diffuse Large B-Cell Lymphoma

  Background and Objective: Approximately half of patients with diffuse large B-cell lymphoma are cured with current chemotherapy regimens. The purpose of this study was to evaluate Bax and Bcl2 expression and their relationship with the response to chemotherapy. Materials and Methods This study was a prospective analysis on 44 patients with diffuse large B-cell lymphoma. Their specimens we...

Genetic lesions in diffuse large B-cell lymphomas.

Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma in adults, accounting for 35%-40% of all cases. The combination of the anti-CD20 monoclonal antibody rituximab with anthracycline-based combination chemotherapy (R-CHOP, rituximab with cyclophosphamide, doxorubicin, vincristine and prednisone) lead to complete remission in most and can cure more than half of patients with DLBCL. ...
