Purpose: To assess the feasibility and the results of Bortezomib-based treatment of "high-risk" AL-amyloidosis patients in a hematology ward.
Methods: We report on 52 high-risk amyloidosis patients treated with first-line bortezomib-based chemotherapy.
Results: At day 30 from the beginning of the therapy, 23 patients (44%) achieved a hematological response (complete response plus very good partial response); 14 patients (27%) achieved a partial response; 15 patients (29%) were non-responders. After a median follow-up of 28.5 months, the survival rates were 18/23 (78%) for responders; 9/14 (64%) for partial responders and 3/15 (20%) for nonresponders with a median overall survival of 43, 24 and 11 months, respectively (log-rank test: P < .001). NHYA class I-II, NTproBNP < 6500 ng/L, the hematologic response, and the partial hematological response at day 30 independently predicted the survival. There has been no significant difference (P = .173) in survival between revised Mayo stage III and IV patients although there was a trend toward a better prognosis for Mayo stage III. A suboptimal hematological response at day 30 allowed a later organ response in 12/14 patients (85%) even without therapy change and no modification of the hematological status.
Conclusions: These results show that high-risk AL-amyloidosis patients can be managed safely and effectively in a hematology ward. A partial hematologic response may herald a later better response, organ response, and can allow a subsequent second-line therapy and a good survival.
