Prognostic factors in patients with diffuse large B cell lymphoma: Before and after the introduction of rituximab.

This study attempted to evaluate the usefulness of the International Prognostic Index (IPI) as a prognostic model in patients treated with R-CHOP (rituximab, cyclophosphamide, vincristine, adriamycin and prednisolone) chemotherapy. We compared 279 patients with DLBCL. Among them, 183 received CHOP while 96 received R-CHOP.

Comparative analysis of extra-nodal NK/T-cell lymphoma and peripheral T-cell lymphoma: significant differences in clinical characteristics and prognosis.

Aim: We aimed to compare the frequencies, clinical characteristics, and prognostic factors of peripheral T-cell lymphoma (PTCL) vs. extra-nodal natural killer (NK)/T-cell lymphoma and to characterize the subtypes of extra-nodal NK/T-cell lymphoma.

Methods: We reviewed 97 consecutive patients with PTCL and extra-nodal NKT lymphoma from 2000 to 2006.
