Objective: To compare the efficacy of autologous HSCT (auto-HSCT) with matched sibling donor (MSD) HSCT in Ph(+) ALL and provide a basis for the choice of transplantation method. Methods: We retrospectively investigated the outcomes of 78 adult patients with Ph(+) ALL who underwent auto-HSCT (n=31) and MSD-HSCT (n=47) in Institute of Hematology and Blood Diseases Hospital, CAMS & PUMC, from January 2008 to December 2017. The overall survival (OS) rate, leukemia-free survival (LFS) rate, cumulative incidence of relapse (CIR) rate, nonrelapse mortality (NRM) rate, and the impact of achievement of complete molecular response (CMR) within 3 months and sustaining CMR up to transplantation (s3CMR) on transplantation method were explored. Results: The median time of neutrophil and platelet reconstitution in auto-HSCT and MSD-HSCT groups were 12 (10-29) days vs14 (11-24) days (P=0.006) and 17.5 (10-62) days vs 7 (10-33) days (P=0.794) , respectively. In the MSD-HSCT group, the incidence of Ⅱ-Ⅳ and Ⅲ-Ⅳ acute graft-versus-host disease (GVHD) was 27.7% (13/47) and 8.5% (4/47) , respectively. The incidence of limited and extensive chronic GVHD was 17.0% (8/47) and 12.8% (6/47) , respectively. The estimated CIR, NRM, LFS, and OS at 3 years were not significantly different between auto-HSCT and MSD-HSCT groups (P>0.05) . For 44 patients who achieved s3CMR, 3-year OS[ (84.0±8.6) % vs (78.0±8.7) %, P=0.612], LFS[ (70.3±10.3) % vs (68.2±10.1) %, P=0.970], CIR[ (24.9±10.0) % vs (14.4±8.0) %, P=0.286], and NRM[ (4.7±4.7) % vs (17.4±8.1) %, P=0.209] of the auto-HSCT and MSD-HSCT groups were not significantly different. However, for 34 patients who did not reach s3CMR, 3-year cumulative relapse rate of patients in the auto-HSCT group was significantly higher than MSD-HSCT group[ (80.0±14.7) % vs (39.6±10.9) %, P=0.057]. Conclusions: auto-HSCT with maintenance therapy after HSCT appears to be an attractive treatment option for patients with Ph(+) ALL especially for those with s3CMR maintained up to transplantation. For non-s3CMR patients, allogeneic transplantation may be more effective from lower relapse.
