Philadelphia-positive acute lymphoblastic leukemia (Ph+ ALL) still represents a major challenge. We report the experience of the Italian Association of Pediatric Hematology and Oncology (AIEOP) with allogeneic hematopoietic stem cell transplantation (HSCT) in children with Ph+ ALL from 1990 to 2008. Sixty-nine patients received HSCT from either a related (37, 54\%) or an unrelated (32, 46\%) donor. Twenty-five patients (36\%) underwent transplantation before 2000 and 44 (64\%) after 2000. Twenty-three patients (33\%) received Imatinib mesylate treatment before HSCT and seven (10\%) after HSCT. After a median follow-up of 56 months, the overall survival (OS) probability was 51\% (95\% confidence interval [CI], 38-63), the leukemia-free survival (LFS) was 47\% (95\% CI, 34-59), transplantation-related mortality (TRM) was 17\% (95\% CI, 10-30), and relapse incidence (RI) was 36\% (95\% CI, 26-50). Transplantation in first complete remission, female gender, and lower WBC count at diagnosis were associated with a better LFS in both univariate and multivariate analyses. Patients with p210 transcript had a trend for a worse prognosis compared with those who had the p190 transcript. Our series confirms the role of HSCT in the eradication of Ph+ ALL. Early HSCT is recommended once morphologic remission is obtained.
