Abstract
T-cell acute lymphoblastic leukemia (T-ALL) is a rare disease usually treated with intensive, high-dose consolidation chemotherapy followed by an allotransplant in a substantial number of patients. The data of the RALL-2009 study on 125 adult T-ALL patients suggest that similar total chemotherapy doses given less intensively over a longer interval without interruptions and with an auto- rather than an allotransplant produce outcomes like current more intensive protocols and an allotransplant: 9-year cumulative incidence of relapse (CIR), leukemia-free survival (LFS), and survival were 24% (95% CI 16-33%), 70% (95% CI 59-79%) and 62% (95% CI 51-72%). In a landmark analysis, subjects achieving a complete remission and receiving an autotransplant had a lower 9-year CIR (9% [95% CI 2-22%] vs. 29% [95% CI 16-43%]; p = 0.0076) and better LFS (91% [95% CI 79-98%] vs. 58% [95% CI 41-74%]; p = 0.0009) and survival (92% [95% CI 77-99%] vs. 60% [95% CI 44-77%]; p = 0.001) compared with subjects not receiving an autotransplant. In a multivariate analysis, white ...
