在2013年8月26日在线出版的《临床肿瘤学杂志》(Journal of Clinical Oncology)上,发表了中国人民解放军南京八一医院秦叔逵教授等人的一项临床III期研究结果。研究旨在确定与阿霉素相比,FOLFOX4(氟尿嘧啶、亚叶酸钙及奥沙利铂灌注)姑息化疗方案是否可为晚期肝细胞癌(HCC)患者带来生存获益及疗效。

这项在中国大陆、台湾地区、韩国及泰国进行的多中心、开放标签、随机临床III期研究共包括371例18至75岁患者,这些患者患有局部晚期或转移性HCC,无法进行根治性切除或局部治疗。患者按1:1的随机分配比例接受FOLFOX4 (n = 184)或阿霉素(n = 187)治疗。研究主要终点为总生存期(OS),次要终点包括无进展生存期(PFS)、缓解率(RR,据RECIST第10版)及安全性。

根据预定的最终分析结果,FOLFOX4方案组患者的中位OS为6.40个月,阿霉素组患者为4.97个月。FOLFOX4方案组患者的中位PFS为2.93个月,阿霉素组患者为1.77个月。FOLFOX4方案组RR为8.15%,阿霉素组为2.67%。根据随访后续结果,FOLFOX4方案组仍保持OS增长趋势。此外,毒性特征与FOLFOX4方案既往经验一致;两组间3至4级不良事件比例类似。

秦叔逵等人认为,尽管本研究未达到主要终点,但FOLFOX4方案的OS改善趋势以及PFS和RR提高的结果均表明,该治疗方案或可为亚洲患者带来部分临床获益。此外,从上述数据中尚不能得出FOLFOX4方案可取得OS获益的相关结论。

研究背景:

肝细胞癌(HCC)为亚洲第三大常见肿瘤,其原因为,该地区肝细胞癌的主要诱发病原——慢性乙肝病毒(HBV)及丙肝病毒(HCV)——感染率较高。其中仅中国一国的年HCC发病率即占全球HCC病例总数的55%。

多数亚洲HCC患者为局部晚期或转移性病情,这些患者不适于接受根治性治疗。此类患者预后较差,在支持性治疗的情况下,患者的中位生存时间仅为3至4个月。因此,目前亟需有效的医疗手段以满足亚洲及世界范围的晚期HCC患者需求。

众所周知,由于HCC的异质性及病因的多样性,HCC对常规全身性化疗手段具有较高的耐药性。在分子靶向药物索拉非尼问世之前,尚没有标准的全身性药物或治疗方案证明可为HCC患者带来明显的生存获益,而索拉非尼出现后,已成为一种标准的治疗手段。

在进行本项研究设计时,索拉非尼仍处于临床研究阶段,尚未批准用于实际应用,并且之前也未有全身性化疗方案被推荐用作HCC标准治疗方案。临床II期研究表明,含奥沙利铂(OXA)的数项治疗方案对晚期HCC具有临床活性。在一项针对中国HCC患者进行的临床II期研究中,通过FOLFOX4(氟尿嘧啶、亚叶酸钙及奥沙利铂灌注)方案,患者的中位总生存期(OS)为12.4个月,至出现进展的中位时间为2.0个月,缓解率为18.2%。结合该方案的安全性可以接受,因此上述结果为进一步考察提供了支持。
