76例远端胆管癌生存分析
Prognosis of patients with distal bile duct cancer
目的 分析76例远端胆管癌的临床和随访资料,研究影响远端胆管癌预后的因素.方法 回顾性分析1996年1月至2006年12月76例远端胆管癌患者的临床资料,以Cox回归模型,选择若干对预后可能产生影响的因素进行统计学分析,筛选影响预后的独立因素.结果 76例患者中,男性46例,女性30例,年龄21~88岁,中位年龄65岁.63例行手术治疗,其中21例行姑息性手术,42例行根治性切除术.根治术后1、3、5年的生存率分别为88%,41%,29%,中位生存期为33个月,根治性手术明显好于姑息性性手术(P=0.000).38例患者死于肝转移或术后复发.统计分析显示,患者的预后与年龄、性别、不同的肿瘤大小及分化情况、胰腺浸润、十二指肠浸润等因素无明显相关;而与是否行根治性手术以及是否存在肝转移显著相关.结论 根治性手术切除是主要的治疗措施,预防和治疗肝转移对于改善远端胆管癌患者的预后有重要意义.
更多Objective To assess the long-term survival and prognosfie factors in a series of patients with distal bile duet carcinoma. Methods A retrospective clinical analysis was made on 76 cases of distal bile duct cancer who were admitted into our hospital from January 1996 to December 2006. Clinicopathologic factors with possible prognostic significanees were selected and analyzed. Survival was calculated with the Kaplan-Meier method. A multivariate analysis of these individuals was performed using the Cox proportional Hazards Model. Results There were 46 males and 30 females. The age ranged from 21 to 88 years with a mean of 65.21 patients received palliative surgery including, bypass procedure, intraoperative biliary stenting, or percutaneous transhepatie biliary drainage. Radical resection was performed on 42 cases and the 1-, 3- and 5-yeur survival rates were 88.0%, 41.3% and 29.2% respectively. 38 cases died of liver metastasis or recurrence. In multivariate analysis, surgical procedure (P = 0.006) and liver metastasis (P = 0.008), but not sex, age, invasion of pancreas, invasion of duodenum, diameter or differentiation of tumor, were significant independent prognostic factors. Conclusions Radical resection is only curative treatment modality. Prevention on postoperative liver metastasis is essential for improving survival.
