可切除肝门部胆管癌预后影响因素分析

Prognostic factors of survival in patients with resectable hilar cholangiocarcinoma

目的 研究对肝门部胆管癌预后影响最大的CA19-9的截点值,探索手术切除肝门部胆管癌患者的预后因素.方法 回顾性分析2003年4月至2009年1月于东方肝胆外科医院手术治疗的168例肝门部胆管癌患者资料.单因素分析其CA19-9水平对判断预后最有价值的截点,后行多因素分析,得出独立预后因素.结果 术前CA19-9水平对预后判断最有价值的截点值为150 kU/L（P＜0.001）.单因素分析显示年龄、肿瘤大小、分化程度、Bismuth-Corlette分型、门静脉侵犯、肝动脉侵犯、术前减黄、淋巴结转移及切缘均会影响肝门部胆管癌的预后.多因素分析证实只有淋巴结转移、切缘及CA19-9是影响肝门部胆管癌预后的独立危险因素.结论 CA19-9水平是影响肝门部胆管癌预后的独立因素,其对预后判断最有价值的截点是150 kU/L.结合术前CA19-9水平不仅有助于肝门部胆管癌患者的术前分期评估,而且有助于决定是否行腹腔探查并推断肝门部胆管癌的预后.

Objective To investigate the appropriate cutoff point of CA19-9 in prognosis and to determine other potential prognostic factors which may affect survival of patients with hilar cholangiocarcinoma （HC） after radical surgery.Methods 168 patients who had undergone radical surgery for hilar cholangiocarcinoma with R0 and R1 resection were selected for the study.Categorized versions were used in univariate model to determine the appropriate cutoff point of CA19-9.CA19-9 and other clinicopathologic factors were analyzed for their influence on survival using multivariate methods.Results The strongest univariate predictor among the categorized preoperative CA19-9 measures was CA19-9 of less than 150 IU/L （P 〈0.001）.On univariate analysis,age,differentiation,tumor size,Bismuth-Corlette classification,portal vein invasion,lymph node metastasis,hepatic artery invasion,liver invasion,preoperative biliary drainage,resection margin and preoperative CA19-9 levels were identified as significant prognostic factors.On multivariable analysis,lymph node metastasis,resection margin and preoperative CA19-9 levels were independent prognostic factors of survival.Conclusions A raised preoperative CA19-9 level was an independent prognostic factor of survival for hilar cholangiocarcinoma.The most discriminative cutoff point of CA19-9 for prognosis was at 150 kU/L.
