术中腹腔氟尿嘧啶缓释剂留置方式对进展期胃癌患者预后影响及安全[基金项目]国家自然科学基金(81071652/H1602)[摘要]目的探讨术中腹腔氟尿嘧啶缓释剂留置方式对进展期胃癌患者预后的影响及安全性。方法选择2008年6月~2012年4月我院术中腹腔植入氟尿嘧啶缓释剂游离留置32例(A组),术中植入氟尿嘧啶缓释剂表面包覆留置35例(B组),未采用腹腔内氟尿嘧啶缓释剂植入30例(C组),分析术后外周血T细胞亚群改变,不良反应及1、2、3年生存率、复发率、转移率。结果A组和B组术后CD3+T细胞、CD4+T细胞占比及CD4+/CD8+均呈减少趋势(P<0.05),A组减少较B组更为显著,A组CD3+T细胞、CD4+T细胞占比及CD4+/CD8+术后1、3、7d均显著低于C组(P<0.05),B组仅CD3+T细胞术后1天显著低于C组(P<0.05)。三组不良反应比较差异均无统计学意义(P>0.05)。2、3年A组和B组生存率显著高于C组,复发率、转移率显著低于C组(P<0.05),A组和B组1、2、3年生存率、复发率、转移率差异无统计学意义(P>0.05)。结论术中腹腔氟尿嘧啶缓释剂植入可有效提高患者远期生存率降低复发和转移率,植入氟尿嘧啶缓释剂表面包覆留置方式可减少对免疫功能的抑制作用,安全性较好。[关键词]胃癌,进展期;氟尿嘧啶;腹腔化疗;生存期;免疫功能[]R735.3[文献标识码]B[]1673-9701(2014)19-0008-04Peritonealcatheterfluorouracilsustainedreleasemannerprognosisandsafetyofpatientswithgastriccanceradvanced激ANGZhenghua1激NHongchuan21.AbdominalSurgicalOncology,激nhuaGuangfuHospital12wardsinZhe激angProvince,激nhua321000,China;2.DepartmentofGeneralSurgery,SirRunRunShawHospital,SchoolofMedicineofZhe激angUniversity,Hangzhou310016,China[Abstract]ObjectiveTostudytheperitonealcatheterfluorouracilsustainedreleasemannerprognosisofpatientswithadvancedgastriccancerandsecurity.MethodsJune2008toApril2012inourhospitalperitonealimplantsfluorouracilreleaseagentfreeindwelling32cases(Agroup),intraoperativefluorouracilsustainedreleaseimplantcoatedcatheter35cases(Bgroup)didnotusetheintraperitonealfluorouracilsustainedreleaseimplant30cases(Cgroup),afteranalyzingchangesinperipheralbloodTcellsubsets,adversereactionsand3-yearsurvival,recurrencerate,thetransferrate.ResultsAgroupandBgroupwereCD3+Tcells,CD4+TcellpercentageandCD4+/CD8+showedadecreasingtrend(P<0.05),AgroupdecreasedmoresignificantlythaningroupB,AgroupCD3+Tcells,CD4+TcellpercentageandCD4+/CD8+1,3,7daysaftersurgeryweresignificantlylowerthaningroupC(P<0.05),Bgroup,onlyCD3+TcellswassignificantlylowerafteronedayingroupC(P<0.05).Adversereactionscomparedthreegroupsshowednosignificantdifference(P>0.05).2,3yearssurvivalrateingroupAandgroupBweresignificantlyhigherthaningroupC,therecurrencerate,metastasisrateweresignificantlyloweringroupC(P<0.05),AgroupandBgroupand3-yearsurvival,recurrencerate,metastasisratewerenosignificantdifference(P>0.05).ConclusionIntraoperativeperitonealfluorouracilsustainedreleaseimplantcaneffectivelyimprovethelong-termsurvivalinpatientswithreducedratesofrecurrenceandmetastasis,fluorouracilsustainedreleaseimplantcoatedindwellingwaystoreducetheinhibitoryeffectonimmunefunction,bettersecurity.[Keywords]Advancedgastriccancer;Fluorouracil;Intraperitonealchemotherapy;Survival;Immunefunction进展期胃癌约占我国胃癌80%,病情进展迅速,肿瘤侵袭性、转移性强,手术是目前有效的治疗手段,但术中仍无法完全清除腹腔中脱落的肿瘤细胞,术后腹腔环境宜于肿瘤细胞的存活和生长,可能造成肿瘤播散、种植或随血液循环转移,术后复发、转移的可能性较大[1]。氟尿嘧啶是特异性抗肿瘤药物,术中植入氟尿嘧啶缓释剂有利于持续杀灭残留肿瘤细胞,从而减少复发和转移,但氟尿嘧啶对免疫系统可能...
