Abstract:
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 78primary PTCL-NOS patients who were initially diagnosed and treated in Tianjin Medical University Cancer Institute and Hospital and Tianjin Union Medical Center from June 2004to June 2012were 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 20months, and the three-year overall survival (OS) was56. 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 was13months. Compara-tive analysis showed that the ORR and three-year OS were statistically significant ( P<0. 05), but the relapse rates ( 57. 1% versus 77. 2%) and three- year OS were similar ( P>0. 05). The incidence rates of Ⅲ/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).
