Treatment for patients with stage IV indolent lymphoma ranges from watchful waiting to intensive chemotherapy and stem cell transplantation. In this trial we compared 2 induction regimens followed by 1 year of interferon maintenance therapy. Fludarabine, mitoxantrone (Novantrone), and dexamethasone (FND) were compared with an alternating triple therapy (ATT) regimen (CHOD-Bleo, ESHAP, and NOPP). Maintenance interferon/dexamethasone was given for 1 year in both treatment arms. Endpoints were comparisons of remission rates, survival, failure-free survival (FFS), molecular response rates, and toxicities. One hundred forty-two patients with previously untreated stage IV indolent lymphoma were evaluable (73 on FND; 69 on ATT). The overall response rates were 97% for FND and 97% for ATT (P = .9). The median follow-up is 5.9 years. The 5-year survival rates were 84% with FND and 82% with ATT (P = .9); the 5-year FFS rates were 41% with FND and 50% with ATT (P = .02). In a multivariate analysis, factors predicting for longer FFS were β2-microglobulin less than 3 mg/L (P = .01) and ATT treatment (P = .03). ATT was associated with a substantially higher rate of grade 3-4 toxicities than FND. In conclusion, both regimens were associated with high rates of response and survival. ATT was associated with substantially longer FFS, but it was more toxic than FND.
