摘要

Background:Both of UFT-/Tegafur-based postoperative chemotherapy and postoperative radiotherapy have made large progress in treatment of early-stage non-small cell lung cancer.While it is unclear that,whether UFT-/Tegafur-based postoperative chemotherapy is superior to postoperative radiotherapy for early-stage non-small cell lung cancer with no direct evidence.Methods:Electronic databases(Pubmed,embase,cochrane library and clinicaltrials.gov)were searched to obtain relevant studies.This systematic review and meta-analysis is reported in accordance with the Preferred Items for Systematic Reviews and Meta-analysis(PRISMA)Statement and was registered at International Prospective Register of Systematic Reviews(number CRD42018095979).Sensitive analysis was conducted by excluding overweight studies.Funnel plot and egger’s test were performed to conduct publication bias.Results:Twenty-one randomized control trials were included.Our results suggested UFT-/Tegafur-based postoperative chemotherapy could improve overall survival over postoperative radiotherapy[HR=0.69(0.59-0.80),p=0.000].But subgroup analysis about stage showed there was no significant difference between them,no matter of stage I,II and III.As to chemotherapy regime,both UFT-/Tegafur+platinum+vinca alkaloid[HR=0.68(0.56-0.82),p=0.000]and UFT-/Tegafur only[HR=0.66(0.54-0.79),p=0.000]were superior to radiotherapy.Subgroup analysis about radiotherapy delivery method and dose showed,significant improvement of chemotherapy over radiotherapy for Cobalt-60 only[HR=0.54(0.39-0.75),p=0.000],Cobalt-60 and linac[HR=0.69(0.59-0.81),p=0.000]and≥45 Gy[HR=0.64(0.54-0.75),p=0.000],but not for linac only[HR=0.78(0.60-1.03),p=0.081]and≥45 Gy[HR=0.86(0.67-1.11),p=0.241].Conclusion:UFT-/Tegafur-based postoperative chemotherapy was superior to postoperative radiotherapy for improving overall survival of early-stage non-small cell lung cancer,but it is not always so under certain circumstance,such as RT delivery method and radiation dose.Of course,it is imperative to furt
