摘　　要：背景与目的:根据目前共识,不良病理学特征仅与Ⅱ期结直肠癌的辅助治疗相关。作为重要的预后影响因素,我们进一步挖掘基于这些不良病理学特征来识别潜在复发和指导临床治疗的可能性。方法:本研究是回顾性队列研究。回顾性分析2008年—2018年复旦大学附属肿瘤医院大肠外科行手术治疗的结直肠癌患者的临床数据。本研究经复旦大学附属肿瘤医院伦理委员会批准(审批号:050432-4-2108*),本研究符合赫尔辛基宣言。纳入的9 875例患者中,男性5 859例,女性4 016例,年龄[M(IQR)]60(16)岁(范围:16~94岁)。中位随访时间1 779.0(95%CI:1 750.1~1 807.9)d。生存率分析采用Kaplan-Meier法和log-rank检验,使用Cox多因素分析影响结直肠癌总生存(overall survival,OS)、无病生存(disease-free survival,DFS)和5年无复发生存(recurrence-free survival,RFS)的独立危险因素,构建列线图模型来对患者预后进行评估、分层。本队列研究严格遵循《加强流行病学中观察性研究报告质量》(Strengthening the Reporting of Observational Studiesin Epidemiology,STROBE)指南中的各项条目。结果:根据合并的不良病理学特征数量进行分组,分为5组:Hr_0组(0 incorporating high-risk pathological features,0个不良病理学特征)、Hr_1组(1 incorporating high-risk pathological features)、Hr_2组(2 incorporating high-risk pathological features)、Hr_3组(3 incorporating high-risk pathological features)、Hr_4组(≥4 incorporating high-risk pathological features)。Kaplan-Meier生存曲线结果提示,不同分组之间的OS、DFS和RFS差异均有统计学意义(P<0.001);针对Ⅱ期结直肠癌进行亚组分析,不同Hr分组OS、DFS和RFS的生存曲线不同分组之间出现重叠,相较于全部病例,不同分组的生存差异明显减小,提示伴有单个不良病理学特征的Ⅱ期肠癌患者可能从辅助化疗中获益;RFS的独立预后危险因素包括:年龄、pT分期、pN分期和Hr分组;OS、DFSBackground and purpose:According to current consensus,adverse high-risk pathological features are only associated with adjuvant therapy for stageⅡcolorectal cancer(CRC).As important prognostic factors,we further explored the possibility of identifying patients with potential recurrence and poor prognosis based on these incorporating high-risk pathological features.Methods:This is a cohort study.A retrospective analysis was conducted on clinical data of CRC patients who underwent surgical treatment at the Second Department of Colorectal Surgery,Fudan University Affiliated Shanghai Cancer Center from 2008 to 2018.This study was approved by the Ethics Committee of the Fudan University Shanghai Cancer Center(approval No.:050432-4-2108*),and the study complies with the Declaration of Helsinki.A total of 9875 patients were enrolled,including 5859 males and 4016 females,aged[M(IQR)]60(16)years(range:16 to 94).Median follow-up time was 1779.0 days[95%CI:1750.1-1807.9].We used the Kaplan-Meier method to plot survival curves for different groups.Cox multivariate analysis was used to identify independent risk factors for 5-year overall survival(OS),disease-free survival(DFS)and recurrence-free survival(RFS).Finally,a column chart model was constructed to evaluate and stratify patient prognosis.The Strengthening the Reporting of Observational Studies in Epidemiology(STROBE)checklist was followed for this cohort study.Results:According to the number of incorporating high-risk pathological features,patients were divided into five groups:Hr_0 group(0 incorporating high-risk pathological feature),Hr_1 group(1 incorporating high-risk pathological feature),Hr_2 group(2 incorporating high-risk pathological features),Hr_3 group(3 incorporating high-risk pathological features),and Hr_4 group(4 or more incorporating high-risk pathological features).The Kaplan-Meier survival curve results indicated significant differences in OS,DFS and RFS among different groups(all P<0.001).Subgroup analysis was conducted on stageⅡcolorectal cance
