摘要: 目的 原发灶切除对Ⅳ期结直肠癌患者的生存获益一直存有争议,本研究主要探讨原发灶切除联合化疗对Ⅳ期结直肠癌患者的预后影响。方法 通过收集SEER数据库2010~2015年诊断为Ⅳ期的结直肠癌患者共4108例,根据治疗方式分为无原发灶切除+无化疗组、单纯原发灶切除组、单纯化疗组、原发灶切除+化疗组。采用Kaplan-Meier法绘制生存曲线,Log-rank法比较不同治疗方式的生存差异,应用Cox比例风险回归模型评估Ⅳ期结直肠癌的预后因素。结果 年龄≥60岁、黑种人、右半结肠、分化程度差、伴有淋巴结转移、多发转移、CEA升高是Ⅳ期结直肠癌预后的危险因素,而原发灶切除、化疗是Ⅳ期结直肠癌患者预后的保护因素。在四种治疗方式中,原发灶切除+化疗组的预后最好。结论 不论是ⅣA期还是ⅣB期结直肠癌,与单纯全身化疗相比,原发灶切除联合化疗可以明显提高患者的生存时间。

Abstract: Objective The survival benefit of primary tumor resection on patients with stage Ⅳ colorectal cancer has been controversial. This study aimed to investigate the prognostic impact of primary tumor resection combined with chemotherapy on patients with stage Ⅳ colorectal cancer. Methods A total of 4108 patients diagnosed with stage Ⅳ colorectal cancer in the SEER database from 2010 to 2015 were enrolled and divided into no primary tumor resection + no chemotherapy group, primary resection alone group, chemotherapy alone group, and primary tumor resection + chemotherapy group according to the treatment methods. The Kaplan-Meier method was used to draw survival curves, the Log-rank method was used to compare the survival differences among different treatment methods, and the Cox proportional risk regression model was applied to assess the prognostic factors of stage Ⅳ colorectal cancer. Results Age ≥60 years, Blacks, right hemicolon, poor differentiation, with lymph node metastasis, multiple metastasis, and elevated CEA were the risk factors for prognosis of stage Ⅳ colorectal cancer, while primary tumor resection and chemotherapy were the protective factors for prognosis of stage Ⅳ colorectal cancer patients. Among the four treatment modalities, the prognosis of the primary tumor resection+chemotherapy group was the best. Conclusion In both stage ⅣA and ⅣB colorectal cancers, primary tumor resection combined with chemotherapy significantly improves patient survival compared to systemic chemotherapy alone.
