Zhongguo Shi Yan Xue Ye Xue za Zhi 2018 August
OBJECTIVE: To evaluate the therapeutic safety and efficacy of VDMP re-induction regimen in Chinese children with relapsed acute lymphoblastic leukemia (ALL).
METHODS: Forty-one patients with relapsed ALL were prospectively enrolled in this study. All the patients were distributed in 3 children's hospitals and treated with VDMP regimen as the first re-induction chemotherapy. Therapeutic efficacy and side-effects were analyzed.
RESULTS: The ratio of male to female was 27:14. The median age was 7.9 (2.2-15.4) years old. Patients relapsed at very early, early, and late stage were 7 cases, 11 cases, and 23 cases, respectively.The immunophenotype analysis showed that 38 cases were B-ALL, and 3 cases were T-ALL. All patients suffered from grade 4 of neutropenia and forty(97.6%) cases got infection, of them one case died. Thirty-nine(95.1%) cases had nonhematologic adverse event at least one organ involved grade 3 in 38 out of 41 cases, the VDMP therapy was completed, 34(89.5%) cases achieved a complete remission (CR), 1 case achieved partial remission(PR), and 3 cases didn't get remission. Follow-up data of 38 cases with completing VDMP chemotherapy were obtained, only one case was lost. Among 37 cases available for evaluation, 16 cases received allo-hematopoietic stem cell transplantation(allo-HSCT) after chemotherapy, and 13 patients survived, while 21 cases did not receive allo-HSCT(treated with chemotherapy only), and 8 patients survived.The overall survival rate of allo-HSCT group was significantly higher than that of those treated with chemotherapy only(P<0.05).
CONCLUSION: VDMP re-induction regimen is effective and well tolerable for pafients in the treated children with relapsed ALL. After remission, allo-HSCT is recommended with the aim of long survival.
