ASCO 2014:荟萃分析显示5FU一线双药化疗改善老年CRC的PFS

2014-05-23 佚名 dxy

对于老年转移性结直肠癌(CRC)的治疗(> 70岁或> 75岁),一线双药化疗( FOLFOX或FOLFIRI 方案)与单药化疗相比(5FU),前者的临床获益目前仍存有争议。法国Bobigny的Avicenne医院的研究者Gaetan Des Guetz等对所有已发表的III期临床结果进行了一项荟萃分析,以期解决这个问题。 该研究收集的数据源自PubMed中搜索,搜索关键词为:转移性结

对于老年转移性结直肠癌(CRC)的治疗(> 70岁或> 75岁),一线双药化疗( FOLFOX或FOLFIRI 方案)与单药化疗相比(5FU),前者的临床获益目前仍存有争议。法国Bobigny的Avicenne医院的研究者Gaetan Des Guetz等对所有已发表的III期临床结果进行了一项荟萃分析,以期解决这个问题。

该研究收集的数据源自PubMed中搜索,搜索关键词为:转移性结直肠癌、 III期研究、奥沙利铂、伊立替康、生存期等。此外,该研究还筛查ASCO和欧洲肿瘤内科学会( ESMO )的会议录。一些已经发表的研究结果符合这项研究的纳入标准。

分析选择了总生存期( OS)和无进展生存期(PFS )作为有效性结果 。如数据中含有毒性数据,该研究也对毒性作出再评价。研究的风险比(HRs )及其95 %可信区间(CI)也将被收集和汇总用于分析。按照惯例,HRs < 1代表较好的结果。p值< 0.05时认为差异有统计学显著意义。采用固定效应模型进行分析。数据分析采用了综合性的荟萃分析软件( BIOSTAT,Englewood, NJ,USA)。

分析共纳入5项原研试验(Mitry, and Koopman两者评估伊立替康,Seymour and Ducreux三者评估奥沙利铂),以及已发表的1项比较FOLFIRI和5FU的荟萃分析结果 (Saltz 、Douillard 、Köhne和Seymour )。

在研究报告中,共纳入1,225例病例( 70%为男性)。在年龄方面,研究选取的年龄截止值为:奥沙利铂试验70岁,伊立替康试验75岁。除Mitry 和 Seymour FOCUS2试验外,90 %的患者PS评分达到0-1,而在Mitry 和 Seymour FOCUS2试验中包含了30%的PS2患者。

总体而言,双药治疗与5FU单药治疗比较,对OS没有改善(HR= 1.00 ;CI:0.89-1.13),但却显著改善了PFS (HR=0.82;CI:0.72-0.93)。 当进行单独评估时,研究者发现FOLFIRI和FOLFOX能显著改善PFS(分别为HR=0.83; 0.68-1.000.68-0.97和HR=0.81,0.68-0.97)。

FOLFIRI主要的3/4级毒性反应包括:腹泻、恶心、呕吐、白细胞减少,发生率明显高于5FU单药治疗。

通过荟萃分析,研究者认为奥沙利铂或伊立替康加入5FU化疗治疗70岁以上的老年转移性大肠癌,可显著改善PFS ,但可能增加与伊立替康相关的毒性。

  6月4日在线发表于J Clin Oncol的一项比较结直肠癌(CRC)原发灶与转移灶、转移灶之间基因突变情况的研究显示,TP53突变在转移灶中更为常见(53.1%对30.3%),而BRAF突变则在原发肿瘤中更多。   比较基因组杂交(CGH)数据显示,造成原发肿瘤与转移灶突变以及基因拷贝数分布差异的原因,可能是多个不同的CRC原发病灶或治疗相关效应。 原始文献: Va
