PURPOSE: In the last years, fludarabine (FLU) alone or in combination with other drugs has been reported to be effective in the treatment of previously treated low-grade non-Hodgkin's lymphomas (LG-NHL). The aim of this study was to define the therapeutic efficacy and toxicity of a combination of FLU and mitoxantrone (FN regimen) in untreated LG-NHL. PATIENTS AND METHODS: We used a two-drug combination of FLU (25 mg/m2 i.v. on days 1 to 3) and mitoxantrone (10 mg/m2 i.v. on day 1) to treat 27 previously untreated patients with LG-NHL, Chemotherapy was repeated every four weeks for a total of six cycles. Among 27 patients, 17 (63%) were diagnosed with follicular, 6 (22%) with small lymphocytic, and 4 (15%) with immunocytoma subtypes. RESULTS: Of the 27 patients, 18 (67%) achieved complete response (CR) and 6 (22%) partial response, while the remaining 3 (11%) showed no benefit from the treatment. Regarding histology, in the follicular subtype we observed an overall response rate of 94%, with a 76.5% CR rate. The estimated two-year relapse-free survival was 83%, and overall survival was 92%. Hematologic grade 3-4 toxicity was seen in only five (3.3%) patients; no opportunistic infections or deaths were associated with the administration of the FN regimen. CONCLUSIONS: These preliminary data show that the FN regimen is a very active, well-tolerated combination chemotherapy for untreated patients with advanced LG-NHL.
