摘要

摘要: 目的探讨直肠癌患者术前临床分期及癌胚抗原与术后预后相关分析。方法收集恩施州中心医院2013年10月至2015年10月直肠癌患者200例；收集患者病理T、N、M分期、术前CEA值、病灶所在肠管位置、累及肠管长度（CT图像测量）、累及肠圈比例、肠周淋巴结是否阳性、环周切缘是否阳性、距离肛门距离、壁外血管是否受浸润，这几个指标为回顾性收集资料；随访观察患者术后是否发生复发和转移2个结果，并记录发生复发、转移、死亡时间。研究方法：用Cox多因素相关分析上述几个指标与患者术后发生复发、转移2个结果相关分析，并找到预测术后发生复发、转移的因素。总生存时间用Kaplan - Meier曲线描述复发和转移患者，并用Log-Rank检验其差异。结果与术后发生转移相关因素分别为N分期P = 0.001；HR = 11.22；95%CI（2.55，49.25）、术前CEA值P < 0.001，HR = 1.00；95%CI（1.002，1.006），这2个因素与术后发生远处转移有相关性；与术后发生局部复发相关的因素为T分期P = 0.036；；HR = 1.726；95%CI（1.03，2.87）、术前CEA值P = 0.034；HR = 1.00；95%CI（0.99，1.005）。结论 T分期与术后局部复发有显著相关，N分期与术后远处转移有相助相关性。术前T分期能预测直肠癌术后局部复发；术前N分期与CEA能预测直肠癌术后远处转移。

Abstract: Objective To explore the correlation between preoperative clinical stage, carcinoembryonic antigen and postoperative prognosis in patients with rectal cancer. Methods 200 patients with rectal cancer from October 2013 to October 2015 were collected from The Central Hospital of Enshi Prefecture. Pathological T, N, AND M staging, preoperative CEA value, lesion location, length of involved bowel （measured by CT image）, proportion of involved bowel, positive periintestinal lymph nodes, positive circumferential resection margin, distance from anus, and infiltration of extraneous vessels were collected retrospectively. The patients were followed up to observe whether the patients had recurrence, metastasis and death after surgery, and the time of recurrence, metastasis and death was recorded. Cox multivariate correlation analysis was used to analyze the correlation between the above indicators and postoperative recurrence and metastasis, and to find the factors that predicted postoperative recurrence and metastasis. Recurrence and metastasis were described by Kaplan-Meier curve and their differences were tested by Log-Rank. Results The factors related to postoperative metastasis were N stage, P = 0.001; HR = 11.22; 95%CI （2.55, 49.25）, preoperative CEA value P < 0.001, HR = 1.00; 95%CI （1.002, 1.006）; and these two factors were associated with distant metastasis after surgery. The factors associated with local recurrence were T stage （P = 0.036）; HR = 1.726; 95%CI （1.03, 2.87）, preoperative CEA value P = 0.034; HR = 1.00; 95%CI （0.99, 1.005）. Conclusion T staging was significantly associated with postoperative local recurrence, and N staging was associated with postoperative distant metastasis. Preoperative T staging can predict postoperative local recurrence of rectal cancer. Preoperative N staging and CEA can predict postoperative distant metastasis of rectal cancer.
