摘要
目的 探讨影响超系膜切除层面原发结直肠癌患者术后长期生存的危险因素.方法 回顾分析了 2010年1月至2021年12月于中国医学科学院肿瘤医院、北京大学第一医院及赤峰市医院接受根治性手术治疗的局部晚期原发结直肠癌患者的临床资料.通过Cox多因素回归分析,对影响其总生存时间(OS)及无进展生存时间(DFS)的危险因素进行分析.结果 共纳入符合入组和排除标准的局部晚期原发结直肠癌患者共557例,全组患者1年、3年、5年OS分别为90.9%、74.7%、63.2%;1年、3年、5年DFS分别为83.7%、66.9%、62.2%.Cox回归分析最终确定年龄>60 岁(OS:HR=1.980,P<0.001;DFS:HR=1.429,P=0.019)、术前放化疗(OS:HR=1.639,P=0.005;DFS:HR=1.845,P<0.001)、癌 性 侵 犯(OS:HR=1.418,P=0.028;DFS:HR=1.690,P=0.001)、淋巴结转移(OS:HR=1.773,P<0.001;DFS:HR=2.347,P<0.001)及非 R0 切除(OS:HfR=2.138,P=0.004;DFS:HR=2.944,P<0.001)为影响患者 OS 及 DFS 的独立危险因素(P<0.05).结论 年龄大于60岁、术前放化疗、癌性侵犯、淋巴结转移及切缘阳性与局部晚期原发结直肠癌患者较差的预后相关.
Abstract
Objective To explore the risk factors affecting the long-term survival of patients with primary colorectal cancer undergoing beyond mesorectal excision.Methods A retrospective analysis was performed on clinical data of patients with locally advanced primary colorectal cancer who underwent radical surgery between January 2010 and December 2021 at Cancer Hospital of Chinese Academy of Medical Sciences,Peking University First Hospital,and Chifeng Municipal Hospital in China.Cox multivariate regression analysis was used to analyze the risk factors that affect their overall survival time and progression-free survival time.Results A total of 557 patients with locally advanced primary colorectal cancer who met the inclusion and exclusion criteria were included.The overall survival rates at 1 year,3 years,and 5 years were 90.9%,74.7%,and 63.2%,respectively,while the disease-free survival rates at 1 year,3 years,and 5 years were 83.7%,66.9%,and 62.2%,respectively.Cox regression analysis identified age>60(OS:HR=1.980,P<0.001;DFS:HR=1.429,P=0.019),neoadjuvant chemoradiotherapy(OS:HR=1.639,P=0.005;DFS:HR=1.845,P<0.001),cancer invasion(OS:HR=1.418,P=0.028;DFS:HR=1.690,P=0.001),lymph node metastasis(OS:HR=1.773,P<0.001;DFS:HR=2.347,P<0.001),and non-R0 resection(OS:HR=2.138,P=0.004;DFS:HR=2.944,P<0.001)as independent risk factors affecting overall survival and disease-free survival of patients(P<0.05).Conclusion Age over 60,neoadjuvant chemotherapy,cancer invasion,lymph node metastasis and non-R0 resection are associated with poor prognosis in patients with locally advanced colorectal cancer.
