伴有同时性肝转移结直肠癌的外科治疗

目的探讨伴有同时性肝转移结直肠癌的外科治疗及其适应证。方法收集经外科手术治疗的116例伴有同时性肝转移的结直肠癌患者的临床资料,进行生存分析,并通过单因素分析和Cox比例风险模型多因素分析确定患者预后的影响因素。结果116例患者均行结直肠癌原发肿瘤切除,18例行同期肝转移瘤切除。围手术期死亡2例(1.7%),术后发生并发症者17例(14.7%)。全组患者5年生存率为14.29%,肝转移瘤切除患者5年生存率为32.12%。多因素分析显示,肝转移瘤切除、腹腔扩散、介入治疗和全身化疗是影响预后的最主要因素。结论伴有同时性肝转移的结直肠癌患者,选择外科手术切除肿瘤病灶,并辅助综合治疗可延长患者的生存时间。

Surgical treatment for colorectal cancer with simultaneous hepatic metastasis

Objective To investigate the indication of surgical treatment lor primary colorectal cancer with simultaneous hepatic metastasis. Methods 116 colorectal cancer patients with simultaneous hepatic metastasis underwent surgery from January 1990 to December 2001. The data were analyzed using Statistical Package for the Social Sciences (Release 11.5, SPSS, Inc). The survival was estimated using Kaplan-Meier method, and the survival comparison was carried out using the log-rank test. Multivariate analysis was performed using Cox regression. Results Totally, 116 patients received surgical resection for primary colorectal tumor, 18 of them underwent liver metastasis resection simultaneously. Postoperative complication developed in 14.7% of these patients with postoperative death in two patients. The overall 5-year survival rate was 14. 29% . The 5-year survival rate of those who had liver metastasis resection was 32.12%. Multivariate analysis showed that liver metastasis resection, abdominal carcinomatosis, chemotherapy and intervention treatment were the most important prognostic factors. Conclusion Surgical resection of primary colorectal cancer with simultaneous resection of liver metastasis or with combined modality therapies such as chemotherapy and intervention treatment is effective to prolong patient's survival for primary colorectal cancer patient with simultaneous hepatic metastasis.
