Abstract
Takezaki et al. analyzed the outcome of 57 patients with indolent lymphomas treated with Bendamustine plus Rituximab (BR) according to the number of cycles received, showing that patients who discontinued BR after four cycles had similar outcomes compared to patients who received five or six cycles. Considering the similarities but also the differences between indolent lymphomas and chronic lymphocytic leukemia (CLL), we enriched the results obtained with a cohort of CLL patients treated with BR starting from the experience of the Lazio region group on CLL. Out of 115 patients, 97 (84%) received 4-6 cycles of BR, while 18 (16%) received 1-3 cycles. The outcome of the group of patients who received at least 4 cycles was superior in terms of response rate (ORR 96% vs. ORR 83%, p = 0.041; CR 58% vs. CR 28%, p = 0.052 respectively) and PFS [median PFS 52.6 (40.3-64.9) versus 26.2 (19.3-33.0) months, p < 0.001]. The number of patients undergoing 4 cycles of BR (4-cycles group) and 5-6 cycles (over-4-cycles group) was 9 and 88, respectively. Compared to analysis conducted by the Japanese group in indolent lymphomas, in CLL we did not observe any difference between the outcome of the 4-cycles group and the over-4-cycles group in terms of ORR (89% vs. 97%, p = 0.268) and in survival [median PFS 40.8 (13.7-67.8) versus 52.6 (38.7-66.5) months, p = 0.117]. Moreover, we observed that patients who achieved a clinical CR showed overlapping outcomes with patients who received more than 4 cycles [CR vs. non-CR median PFS not reached vs. 11.0 months; over-4-cycles group median PFS 52.6 months (40.3-64.9); p < 0.001]. Nowadays chemoimmunotherapy with BR is reserved to fit elderly CLL patients, and there are many chemo-free treatment options available; therefore, discontinuation after 4 cycles may be permissible in patients who obtained a CR in order to limit toxicity as much as possible.

Abstract
Bendamusutine plus rituximab (BR) regimen is one of the standard regimens for indolent B-cell lymphomas, yet the possibility of reduction of cycles of BR therapy without compromising therapeutic effects is not still uncovered. We retrospectively surveyed 57 cases including 40 follicular lymphoma cases who underwent BR regimen in our institute. The overall response (OR) rate and complete response (CR) rate were 86.0% (95% confidential interval (CI), 74.2-93.7) and 54.4% (40.7-67.6), respectively. Five-year overall survival (OS) and 5-years progression-free survival (PFS) were 76.8% and 45.7%, respectively. We then grouped the patients by the number of administered cycles of BR regimen. PFS was significantly longer in 41 cases of the later cessation group (cycle 4-6) than in 16 cases of the earlier cessation group (cycle 1-3) (p = 0.012, 5-years PFS; 46.8% vs. 35.2%, respectively), and both of OR and CR rate of the former was better than the latter (OR rate; 95.1% vs. 62.5%, p < 0.01, CR rate; 61.4% vs. 31.3%, p = 0.04). Interestingly PFS of twenty-one (36.8%) cases receiving just 4 cycles was longer than that of 20 cases who received five or 6 cycles (p < 0.01, 5-years PFS; 71.8% vs. 23.2%, respectively). Focusing on the group of four cycles, the 12 case with CR revealed longer PFS than seven cases with partial response (PR), and median PFS was not reached in CR cases and 16.9 months in the PR cases (p < 0.01). These results suggest that four cycles at least should be administered if possible, and the outcome of the patients who discontinued BR after four cycles was not inferior to that of the cases who received five or six cycles. In conclusion, discontinuation after four cycles may be permissible in some cases with complete response to BR regimen.
