| Abstrakt: | Objective: To explore the treatment options for younger than 60 years old adults with Ph /BCR-ABL positive acute lymphoblastic leukemia (Ph⁺ ALL). Methods: From January 2001 to June 2012, 42 adult patients were enrolled in the study. All patients received standard VDCP±L ±imatinb (IM) as induction therapy followed by intensive consolidation of modified Hyper-CVAD/MA±IM. At complete remission 1 (CR1), patients with appropriate donor received allogeneic hematopoietic stem cell transplantation (allo-HSCT), the others sequentially received intensive consolidation ±IM and autologous HSCT (ASCT) at molecular CR (MCR), then MM±VP±IM as maintenance therapy. Overall survival (OS), disease free survival (DFS) and relapse rate (RR) were analyzed. Results: CR rate after 1 cycle of induction chemotherapy was 83.3%. 39(92.9%) patients achieved CR. The median DFS and OS were (22.0±3.5) and (37.0±5.3) months respectively, with cumulative RR of (43.7±9.7)% during a median follow-up of 26.5(8-75) months. All 7 patients in CT group relapsed. Two patients received IM pre- and post-ASCT maintained MCR for 35 and 12 months after ASCT. But the other 3 ASCT recipients without IM died of relapse within 1 year. The transplant-related mortality rate in allo-HSCT group was 12.5%. The estimated 3-year OS in allo-HSCT (n=16), ASCT (n=5) and CT (n=7) groups were (66.7±12.2)%, (25.0±21.7)% and (16.7±15.2)%, respectively (P=0.014); meanwhile, the estimated 3-year DFS in those groups were of (56.3±12.4)%, (26.7±22.6)% and 0, respectively (P=0.002). Conclusion: IM combined with intensive chemotherapy significantly increased the CR rate with the improved quality of CR, which highlighted the feasibility of SCT. Allo-HSCT could decrease relapse to produce favorable OS and DFS in CR1 of young adults with Ph⁺ ALL. ASCT combined IM might be the treatment of choice for those achieved MCR but without donors. |
