目的:大量研究表明,外周血中循环肿瘤细胞( CTCs)水平可能与胰腺癌患者生存期有关,但仍有部分研究存在争议性结论。本研究旨在探讨外周血CTCs预测胰腺癌患者临床预后的价值。方法计算机检索Pubmed、Embase、CBm、万方、Web of Science、Cochrane Library、CISCOm、CINAHL、谷歌学术、中国知网等中英文数据库,检索范围从建库至2013-08-01。采用STATA 12.0软件进行分析,计算HR及其95%CI评价CTCs预测胰腺癌患者临床预后的价值。结果本研究共计纳入9项队列研究,共623例胰腺癌患者,包括268例CTCs阳性患者和355例CTCs阴性患者。meta分析结果表明:CTCs阳性表达患者与无进展生存期( PFS)有关〔HR=0.52,95%CI(0.27,0.77), P﹤0.001〕;此外,CTCs阳性组患者总生存期(OS)短于CTCs阴性组患者〔HR=0.73,95%CI(0.54,0.93),P﹤0.001〕。根据种族差异进行亚组分析发现,亚洲人群和欧美人群CTCs阳性组患者的OS均低于CTCs阴性组患者( P﹤0.05)。结论 CTCs阳性表达患者PFS和OS均短于CTCs阴性表达患者,故检测外周血CTCs表达情况对预测胰腺癌的转移或复发及临床预后均具有重要意义。
目的:大量研究錶明,外週血中循環腫瘤細胞( CTCs)水平可能與胰腺癌患者生存期有關,但仍有部分研究存在爭議性結論。本研究旨在探討外週血CTCs預測胰腺癌患者臨床預後的價值。方法計算機檢索Pubmed、Embase、CBm、萬方、Web of Science、Cochrane Library、CISCOm、CINAHL、穀歌學術、中國知網等中英文數據庫,檢索範圍從建庫至2013-08-01。採用STATA 12.0軟件進行分析,計算HR及其95%CI評價CTCs預測胰腺癌患者臨床預後的價值。結果本研究共計納入9項隊列研究,共623例胰腺癌患者,包括268例CTCs暘性患者和355例CTCs陰性患者。meta分析結果錶明:CTCs暘性錶達患者與無進展生存期( PFS)有關〔HR=0.52,95%CI(0.27,0.77), P﹤0.001〕;此外,CTCs暘性組患者總生存期(OS)短于CTCs陰性組患者〔HR=0.73,95%CI(0.54,0.93),P﹤0.001〕。根據種族差異進行亞組分析髮現,亞洲人群和歐美人群CTCs暘性組患者的OS均低于CTCs陰性組患者( P﹤0.05)。結論 CTCs暘性錶達患者PFS和OS均短于CTCs陰性錶達患者,故檢測外週血CTCs錶達情況對預測胰腺癌的轉移或複髮及臨床預後均具有重要意義。

Objective Increasingscientificevidencessuggestthatcirculatingtumorcells(CTCs)inperipheralblood may be a powerful predictor of the prognostic survival time in patients with pancreatic cancer. However,many existing studies have yielded inconclusive results. This meta-analysis aims to assess the prognostic value of CTCs in patients with pancreatic cancer.Methods AnextensiveliterarysearchforrelevantstudieswasconductedonPubmed,Embase,WanfangData,Web of Science,Cochrane Library,CISCOm,CINAHL,Google Scholar,CNKI and CBm databases from their inception through August 1st,2013. The meta-analysis was then performed using STATA 12. 0. The crude hazard ratio( HR)was calculated witha95%confidenceinterval(CI).Results Ninecohortstudieswereincludedinthismeta-analysiswithatotalof623 pancreatic cancer patients. This number included 268 CTCs-positive patients and 355 CTCs-negative patients. Our meta-a-nalysis revealed that patients in the CTCs-positive group were significantly associated with progression -free survival ( PFS )〔HR=0. 52,95%CI(0. 27,0. 77),P﹤0. 001〕. Furthermore,pancreatic cancer patients in the CTCs-positive group also showed worse overall survival(OS)than those in the CTCs - negative group〔HR =0. 73,95%CI(0. 54,0. 93),P ﹤0. 001〕. Subgroup analysis by ethnicity indicated that CTCs-positive patients had worse OS than CTCs-negative ones among bothAsianandCaucasianpopulations(P﹤0.05).Conclusion Inconclusion,ourmeta-analysissuggeststhatbothPFSand OS of CTCs-positive patients with pancreatic cancer are worse than those of CTCs-negative ones. Detection of CTCs in periph-eral blood may be a promising prognostic biomarker for the detection of both the recurrence and metastasis of pancreatic cancer.
