摘要: Purpose: Although rituximab is now routinely used in the treatment of B-cell non-Hodgkin’s lymphoma, mechanism its antitumor effect not clear. One potential action involves antibody-dependent cellular cytotoxicity (ADCC). Two aspects ADCC influence effectiveness this process: susceptibility tumor cells and activation effector via their immunoglobulin G fragment C receptors (FcγRs). Several FcγR polymorphisms have been identified that may affect killing function natural killer macrophages. Patients Methods: The pretreatment from 43 patients with follicular lymphoma were tested for intrinsic to rituximab-mediated ADCC. In addition, FcγRIIIa (CD16) FcγRIIa (CD32) determined an expanded group 87 patients. results then correlated clinical outcome these Results: No difference was found between tumors who clinica...
