Effective Treatment of Indolent Non-Hodgkin’s Lymphomas with Mitoxantrone, Chlorambucil and Prednisone

Since indolent non-Hodgkin's lymphomas (NHL) represent about 35% of all malignant lymphomas and mainly affect elderly patients, availability of a conventional chemotherapy regimen with high efficacy and low toxicity is of clinical importance.We retrospectively analysed 13 patients with advanced indolent NHL who were treated with 6-9 cycles of MCP: mitoxantrone 8 mg/m2 (days 1 and 2), chlorambucil 3 x 3 mg/m2 (days 1-5) and prednisone 25 mg (days 1-5) every 4 weeks.The overall response was 84% (61% complete response, 23% partial response), 1 patient had stable disease and 1 patient experienced progressive disease. Median time to progression was 37 months (95% CI: 20-53) and the median survival has not yet been reached. The main toxicity (66%) was neutropenia (WHO grade III). There was no hair loss and no cardial or neurologic adverse event.In summary, MCP is an effective and well tolerated chemotherapy regimen and is probably an alternative to the more toxic CHOP regimen, especially in older patients.
