Mitoxantrone, etoposide and prednisone (MEP)-based regimens using granulocyte colony-stimulating factor (G-CSF) were designed for relapsed and CHOP-resistant diffuse large B-cell lymphomas in a single institution, and the therapeutic effects and adverse reactions were studied. In a total of 49 patients, the MEP regimen had a 41% (9/22) overall response rate compared with 48% (13/27) for the MEP plus carboplatin (C-MEP) regimen (Chi-squared test, P=0.602). Among 38 CHOP-resistant patients, however, the overall response rate to C-MEP [42% (10/24)] was significantly superior compared with MEP [7% (1/14)] (P=0.023), and the overall survival to C-MEP was superior compared with MEP (P=0.088). Taken together, our results, although non-randomized, suggest that a combination of MEP with carboplatin is better than MEP alone in CHOP-resistant diffuse large B-cell lymphomas.
