Hyper-CVAD方案治疗侵袭性T细胞淋巴瘤的效果和安全性

目的 评价Hyper-CVAD化疗方案治疗侵袭性T细胞淋巴瘤的效果和安全性.方法 对2009年9月至2010年12月在北京协和医院接受Hyper-CVAD方案诱导化疗的34例初诊侵袭性T细胞淋巴瘤患者的疗效和不良反应等资料进行回顾性分析,并进行生存分析.结果 34例患者接受Hyper-CVAD方案诱导化疗后,28例(82.4％)有治疗反应,其中10例(29.4％)获得完全缓解(CR);11例接受造血干细胞移植(包括1例同胞全合异基因造血干细胞移植).中位随访时间16个月(1～82个月),1、3年总生存(OS)率分别为70.2％、41.1％;1、3年无进展生存(PFS)率分别为49.3％、31.6％.化疗不良反应主要为骨髓抑制,18例(52.9％)发生Ⅳ级骨髓抑制;3例因严重感染死亡.Cox多因素分析显示,化疗能否达到CR是PFS的独立影响因素(HR=6.118,95％CI 1.327～28.206,P=0.020);骨髓是否受累(HR=0.270,95％CI 0.101～0.722,P=0.009)和化疗能否达到CR(HR=6.669,95％CI 1.754～25.354,P=0.005)是OS的独立影响因素.结论 Hyper-CVAD方案诱导化疗治疗侵袭性T细胞淋巴瘤的反应率高,但有效持续时间短,远期疗效不佳,同时骨髓抑制严重,感染发生率高.缓解后行自体造血干细胞移植可能提高侵袭性T细胞淋巴瘤的疗效.

Efficacy and safety of Hyper-CVAD regimen for treatment of aggressive T-cell lymphoma

Objective To evaluate the safety and efficacy of Hyper-CVAD intensive chemotherapy regimen in patients with newly diagnosed aggressive T-cell lymphoma. Methods The efficacy, side effects and survival status were retrospectively analyzed in 34 patients with newly diagnosed aggressive T-cell lymphoma who received Hyper-CVAD regimen as induction therapy in Peking Union Medical College Hospital from September 2009 to December 2010. Results Of 34 patients, 28 cases (82.4 ％) showed treatment response, including 10 cases (29.4 ％) of complete response (CR). Eleven patients underwent stem cell transplantation, including 1 case of human leukocyte antigen-identical siblings allogeneic stem cell transplantation. The median follow-up was 16 months (1-82 months), and the overall survival (OS) rate of 1 or 3-year was 70.2 ％ and 41.1 ％ respectively, and progression-free survival (PFS) rate of 1 or 3-year was 49.3 ％ and 31.6 ％ respectively. The major adverse reaction was myelosuppresion, including 18 cases (52.9％) of myelosuppresion with grade Ⅳ. Three patients died of serious infection. Cox regression multifactor analysis showed CR was the only influencing factor for PFS (HR=6.118, 95％CI 1.327-28.206, P=0.020). Marrow involvement (HR= 0.270, 95 ％CI 0.101-0.722, P= 0.009) and CR (HR= 6.669, 95 ％CI 1.754-25.354, P= 0.005) were independent influencing factors for OS. Conclusions Hyper-CVAD regimen has a high response rate for aggressive T-cell lymphoma, but the lasting effectiveness and the short-term efficacy show unfavorable performances. Meanwhile, myelosuppression is serious and infection incidence is high. Autologous hematopoietic stem-cell transplantation after remission may improve the outcome.
