Maintenance rituximab after autologous stem cell transplantation in patients with mantle cell lymphoma.
BACKGROUND High-dose therapy and autologous stem cell transplantation (ASCT) improves outcomes for patients with mantle cell lymphoma (MCL), but relapse ultimately occurs in most patients. Recently presented interim results from a phase III prospective trial suggest maintenance rituximab (MR) after ASCT for MCL improves progression-free survival (PFS). The maturation of these data and any benef...
متن کاملClinical outcome of lymphoma patients after idiotype vaccination is correlated with humoral immune response and immunoglobulin G Fc receptor genotype.
PURPOSE The unique immunoglobulin idiotype (Id) expressed by each B-cell lymphoma is a target for immunotherapy. Vaccination with Id induces humoral and/or cellular anti-Id immune responses. However, the clinical impact of these anti-Id immune responses is unknown. We and others have previously reported that immunoglobulin G Fc receptor (FcgammaR) polymorphisms predict the clinical response of ...
متن کاملExpansion of Fc receptor-bearing T lymphocytes in patients with immunoglobulin G and immunoglobulin A myeloma.
Lymphocytes obtained from the blood of normal individuals and six patients with newly diagnosed multiple myeloma were separated into T and non-T cell populations by rosette-formation with sheep erythrocytes, and were then assayed for the presence of surface membrane Fc receptors. When compared with normal individuals, four patients with IgG myeloma had a three- to fourfold increase in T cells w...
متن کاملRelevance of immunoglobulin G Fc receptor polymorphism to recurrence of adult periodontitis in Japanese patients.
Polymorphonuclear neutrophil (PMN) phagocytic function has been shown to be impaired in some patients with periodontitis. PMN constitutively express members of two immunoglobulin G receptor (Fc gammaR) classes: Fc gammaRIIa (CD32) and Fc gammaRIIIb (CD16). Both receptors exhibit genetically determined structural and functional biallelic polymorphisms, which have been shown to influence PMN phag...
متن کاملRituximab infusion induces NK activation in lymphoma patients with the high-affinity CD16 polymorphism.
Natural killer (NK) cell-mediated antibody-dependent cellular cytotoxicity involving FcγRIIIa (CD16) likely contributes to the clinical efficacy of rituximab. To assess the in vivo effects of CD16 polymorphisms on rituximab-induced NK activation, blood was evaluated before and 4 hours after initiation of the initial dose of rituximab in 21 lymphoma subjects. Rituximab induced NK activation and ...
