The benefit of pre-transplant consolidation in patients with acute lymphoblastic leukemia (ALL) who achieved first complete remission (CR1) has not yet been clearly demonstrated. Here, we aimed to investigate the relationship between the treatments received before transplantation and transplant outcome in Ph-ALL patients who underwent myeloablative allo-HSCT in CR1.A total of 55, 32 (58.2%) men and 23 (41.8%) women, who underwent allo-HSCT with the diagnosis of Ph-ALL were evaluated retrospectively. All patients underwent to allo-HSCT with myeloablative conditioning regimen in the 1st CR from the available donor.In patients who received2 consolidation, the 2-year and 3-year OS was 69% and 65%, respectively, while the 2-year and 3-year OS was 39% and 26%, respectively, in those who received2 consolidation (P =.03). RFS was similar in both groups (P = .8). One year- NRM was found 28% in patients who received ≥ 2 consolidations, and 37% in patients who received2 consolidation (P =.06). L-asparaginase, high dose methotrexate, and cranial treatments given before transplantation had no effect on transplant outcomes (P.05).Contrary to the belief that pre-transplant consolidation is not beneficial in ALL patients who proceed with allo-HCST in CR1, our results showed that consolidation treatments reduce NRM and improve the survival. |
