Popis: To analyze the therapeutic efficacy of different consolidation therapies after induction remission on Ph negative adolescent and young adults with acute B lymphoblastic leukemia, and to explore the effect of different risk factors on prognosis.The treatment and efficacy of 80 Ph negative B-ALL in patients of 16-39 years old in the Hematology Department of 301(65 cases) and 309(15 cases) hospital from 1999 to 2016 are retrospectively analyzed. The patients received combined induction chemotherapy of 4 or 5 chemotherapeutic drugs (VDCLP/ VDLP/ DOLP/ IOLP). After remission patients received consolidation protocols of 3-5 cycls, and then received allo-HSCT or haploidentical HSCT. The median follow-up time was 29 (6-153) months.HSCT was carried out after CR1. The 5-year OS and EFS of allo-HSCT group(n=29) was (73±16)% and (67±17)%, respectively, while those of haploidentical-HSCT group(n=20) were (53±22)% and (53±22)%, respectively, and those of pediatric-inspired protocols(n=31) was (63±17)% and (50±18)%, respectively. The difference between OS and EFS in 3 group was not statistically significant(P0.05). The re-remission rate of recurrent patients was (50±23)%. On the one side, the cumulative incidence of TRM of pediatric-inspired protocol was better than that of HSCT (P0.05). On the other side, the cummulative incidence of relapse (CIR) of pediatric-inspired protocol was poorer than that of HSCT, yet without significant difference (P0.05). The median remission time of CR2 in patients was 14(2-36) months. Univariate and multivariate analysis were performed in 65 patients, and showed an abnormal result of CD13 or CD33 positive, CD22 negative, indicating a poor prognosis(P0.05).In the adolescent and young adult patients with Ph
