Abstract
- Treatment for follicular lymphoma (FL) in the elderly is not well standardized. A phase II, multicentre, single arm trial was conducted in this setting with a brief chemoimmunotherapy regimen. Treatment consisted in four monthly courses of rituximab, bendamustine and mitoxantrone (R-BM) followed by 4 weekly rituximab as consolidation; rituximab maintenance was not applied because the drug was not licensed at the time of enrolment. The primary endpoint was the complete remission rate (CR). Seventy-six treatment-naive FL patients (aged 65-80 and a "FIT" score, according to the Comprehensive Geriatric Assessment) were enrolled. CR was documented in 59/76 patients (78%), partial remission in 12 (16%) and stable/progressive disease in five (6%) with an overall response rate in 71/76 (94%). Median follow-up was 44 months with 3-year progression-free-survival (PFS) and overall-survival of 67% and 92% respectively. Nine deaths occurred, three of progressive disease. The regimen was well tolerated and the most frequent severe toxicity was neutropenia (18% of the cycles). Bcl-2/IGH rearrangement was found in 40/75 (53%) of evaluated patients. R-BM was highly effective in clearing polymerase chain reaction-detectable disease: 29/31 (96%) evaluated patients converted to bcl-2/IGH negativity at the end of treatment. A brief R-BM regimen plus rituximab consolidation is effective and safe in "FIT" elderly, treatment-naive, FL patients, inducing high CR and molecular remission rates with prolonged PFS.
