近日,国际杂志Annals of Surgery刊登了来自台湾的研究人员的研究发现,他们发现,术后使用干扰素α-2b治疗不能阻止肝炎相关的肝细胞癌复发,也不能提高手术切除癌症患者的总体生存期,现在迫切需要其他组合的辅助疗法。相关研究论文“Long-Term Results of a Randomized, Observation-Controlled, Phase III Trial of Adjuvant Interferon Alfa-2b in Hepatocellular Carcinoma After Curative Resection,”刊登在了新一期的Annals of Surgery杂志上。
在这篇报告中,国立台湾大学医学院的陈医生等发现,尽管使用干扰素治疗的试验失败了,但是荟萃分析表明,在消融后使用干扰素α-2b可能有效。
研究者招募了268名病人进行随机试验,手术后辅助干扰素α-2b治疗或者没有干扰素,80%病人是HBV表面抗原阳性,其他人是C型肝炎。略超于5年的随访期发现,58%病人复发,31%死亡,意向性治疗分析发现,5年无复发生存率为44.2%,整体生存率为73.9%。
总体而言,干扰素组的中位无复发生存期为42.2个月,对照组为48.6个月。按照病因分组,HCV病人的干扰素组和对照组的无疾病进展生存期分别为42.2和31.1个月,HBV病人为42.4和49.1个月。这些差别无统计学意义。
可以预见到,干扰素组的副作用更为常见。治疗的病人白细胞减少和血小板减少的发生率显著升高。(生物谷Bioon.com)

Objective: To investigate the clinical efficacy of adjuvant interferon alfa-2b (IFNα-2b) therapy on recurrence-free survival (RFS) of patients with postoperative viral hepatitis-related hepatocellular carcinoma (HCC). Background: Despite most individual trials have failed to meet their primary endpoint, recent pooled-data meta-analyses suggest that adjuvant IFN therapy may significantly reduce the incidence of recurrence in curatively ablated HCC. Methods: Patients with curative resection of viral hepatitis-related HCC were eligible, and were stratified by underlying viral etiology and randomly allocated to receive either 53 weeks of adjuvant IFNα-2b treatment or observation alone. The primary endpoint of this study was RFS. Results: A total of 268 patients were enrolled with 133 in the IFNα-2b arm and 135 in the control arm. Eighty percent of them were hepatitis B surface antigen seropositive. At a median follow-up of 63.8 months, 154 (57.5%) patients had tumor recurrence and 84 (31.3%) were deceased. The cumulative 5-year recurrence-free and overall survival rates of intent-to-treat cohort were 44.2% and 73.9%, respectively. The median RFS in the IFNα-2b and control arms were 42.2 (95% confidence interval [CI], 28.1–87.1) and 48.6 (95% CI, 25.5 to infinity) months, respectively (P = 0.828, log-rank test). Adjuvant IFNα-2b treatment was associated with a significantly higher incidence of leucopenia and thrombocytopenia. Thirty-four (24.8%) of treated patients required dose reduction, and 5 (3.8%) of these patients subsequently withdrew from therapy because of excessive toxicity. Adjuvant IFNα-2b only temporarily suppressed viral replication during treatment period. Conclusions: In this study, adjuvant IFNα-2b did not reduce the postoperative recurrence of viral hepatitis-related HCC. More potent antiviral therapy deserves to be explored for this patient population. This study is registered at ClinicalTrials.gov and carries the identifier NCT00149565.
