Efficacy of Hyper-CVAD/MA and CHALL-01 regimens in the treatment of Philadelphia chromosome-positive adult acute lymphoblastic leukemia patients under 60 years old / 中华血液学杂志

Objective@#To compare the difference of efficacy between traditional Hyper-CVAD/MA regimen and the adolescents inspired chemotherapy regimen, CH ALL-01, in treatment of adult Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) .@*Methods@#In this study we retrospectively analyzed 158 Ph+ ALL patients receiving Hyper-CVAD/MA regimen (n=63) or CHALL-01 regimen (n=95) in our center and Changzheng hospital from January 2007 to December 2017, excluding patients with chronic myeloid leukemia in blast crisis. Tyrosine kinase inhibitor (TKI) was administered during induction and consolidation chemotherapy. Patients who underwent hematopoietic stem cell transplantation received TKI as maintenance therapy.@*Results@#Of them, 91.1% (144/158) patients achieved complete remission (CR) after 1-2 courses of induction. CR rate was 90.5% (57/63) for patients in Hyper-CVAD/MA group and 91.6% (87/95) for patients in CHALL-01 group. There was no difference in CR rates between the two groups (χ2=0.057, P=0.811) . The last follow-up was June 2018. A cohort of 134 CR patients could be used for further analysis, among them, 53 patients received Hyper-CVAD/MA regimen and other 81 patients received CHALL-01 regimen. The molecular remission rates were significantly higher in CHALL-01 group (complete molecular response: 44.4%vs 22.6%; major molecular response: 9.9% vs 18.9%) (χ2=7.216, P=0.027) . For the patients in Hyper-CVAD/MA group, the 4-year overall survival (OS) was 44.81% (95%CI: 30.80%-57.86%) and the 4-year disease free survival (DFS) was 37.95% (95%CI: 24.87%-50.93%) . For patients received CHALL-01 regimen, the 4-year OS was 55.63% (95%CI: 39.07%-69.36%) (P=0.037) and 4 year DFS was 49.06% (95%CI: 34.24%-62.29%) (P=0.015) , while there was no significant difference in 4 year cumulative incidence of relapse (CIR) (P=0.328) or cumulative incidence of nonrelapse mortality (CI-NRM) (P=0.138) . The rate of pulmonary infection was lower in patients received CHALL-01 regimen compared with patients received Hyper-CVAD regimen (43.4% vs 67.9%, χ2=7.908, P=0.005) .@*Conclusions@#Outcome with CHALL-01 regimen appeared better than that with the Hyper-CVAD/MA regimen in Ph+ ALL, which has lower incidence of pulmonary infection, higher molecular remission rate and better OS and DFS.

Objective: To compare the difference of efficacy between traditional Hyper-CVAD/MA regimen and the adolescents inspired chemotherapy regimen, CH ALL-01, in treatment of adult Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph(+) ALL) . Methods: In this study we retrospectively analyzed 158 Ph(+) ALL patients receiving Hyper-CVAD/MA regimen (n=63) or CHALL-01 regimen (n=95) in our center and Changzheng hospital from January 2007 to December 2017, excluding patients with chronic myeloid leukemia in blast crisis. Tyrosine kinase inhibitor (TKI) was administered during induction and consolidation chemotherapy. Patients who underwent hematopoietic stem cell transplantation received TKI as maintenance therapy.

CR rate was 90.5% (57/63) for patients in Hyper-CVAD/MA group and 91.6% (87/95) for patients in CHALL-01 group. There was no difference in CR rates between the two groups (χ(2)=0.057, P=0.811) . The last follow-up was June 2018. A cohort of 134 CR patients could be used for further analysis, among them, 53 patients received Hyper-CVAD/MA regimen and other 81 patients received CHALL-01 regimen. The molecular remission rates were significantly higher in CHALL-01 group (complete molecular response: 44.4%vs 22.6%; major molecular response: 9.9% vs 18.9%) (χ(2)=7.216, P=0.027) . For the patients in Hyper-CVAD/MA group, the 4-year overall survival (OS) was 44.81% (95%CI: 30.80%-57.86%) and the 4-year disease free survival (DFS) was 37.95% (95%CI: 24.87%-50.93%) .

Clinical analysis of Hyper-CVAD/MA regimen and CHOP/CHOP-like regimen in the treatment of 78 patients with peripheral T-cell lymphoma, not otherwise specified (PT-CL-NOS) / 中国肿瘤临床

Objective:To compare the therapeutic efficacy and safety of Hyper-CVAD/MA regimen and CHOP/CHOP-like regimen in the treatment of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). Methods:The 78 primary PTCL-NOS patients who were initially diagnosed and treated in Tianjin Medical University Cancer Institute and Hospital and Tianjin Union Medical Center from June 2004 to June 2012 were retrospectively analyzed. The patients were then divided into two groups:Hyper-CVAD/MA group (n=21) and CHOP/CHOP-like group (n=57). Curative efficacies and toxicities were analyzed by Chi-square test, and survival was estimated by Ka-plan-Meier method. Results: In the Hyper-CVAD/MA group, complete response (CR) was 42.9%, overall response rate (ORR) was 85.7%, median progression-free survival (PFS) was 20 months, and the three-year overall survival (OS) was 56.9%. In the CHOP/CHOP-like group, the CR, ORR, and three-year OS were 28.1%, 59.6%, and 49.6%, respectively, and the median PFS was 13 months. Compara-tive analysis showed that the ORR and three-year OS were statistically significant (P0.05). The incidence rates ofⅢ/Ⅳneutrocytopenia and thrombocytopenia in Hyper-CVAD/MA group (66.7%and 61.9%, respectively) were significantly higher than those of the CHOP/CHOP-like group (22.8%and 14.0%, respec-tively) (P<0.05). Conclusion:Hyper-CVAD/MA regimen can achieve satisfactory efficacy in parents with PTCL-NOS, and toxicity can be controlled with granulocyte colony stimulating factor (G-CSF).
