结直肠癌伴同时性肝转移的治疗

目的 探讨结直肠癌伴同时性肝转移患者的临床相关病理因素以及手术治疗.方法 回顾性分析1994年8月至2006年12月收治患者的临床资料及随访结果,比较结直肠癌无肝转移和有同时性肝转移患者的病理特点及不同程度肝转移患者和不同手术处理的预后.结果 2019例原发性结直肠癌患者中发生同时性肝转移者166例(8.10%).多因素分析显示:术前CEA水平、Ducks分期、肿瘤分化程度与浆膜浸润是同时性肝转移发生的高危因素;同时性肝转移术后1、3、5年生存率分别为69%、21%、9%;不同程度肝转移(H1、H2、H3)组间预后差异有统计学意义(X2=23.35,P<0.01).根治性手术切除组总体生存率明显高于姑息切除和未能切除组生存率(X2=21.18,P<0.01);姑息切除组和未切除组近期生存率差异有统计学意义(P<0.01),远期生存率差异无统计学意义(P=0.13).结论 结直肠癌伴同时性肝转移患者肝转移程度不同预后也不同.能够根治性切除的结直肠癌伴同时性肝转移预后较好,姑息切除原发病灶可提高近期预后和生活质量.

The management of colorectal cancer with synchronous liver metastases

Objective To investigate the clinical pathologic characters of colorectal cancer with simultaneous hepatic metastasis and the prognosis. Methods From Aug. 1994 to Dec. 2006, 2019 cases of colorectal carcinoma were admitted, among them there were 166 patients of colorectal cancer with synchronous liver metastases receiving surgical therapy. Results were analyzed retrospectively using the software of SPSS. Results These 166 patients with synchronous liver metastases from colorectal cancer accounted for 8.1% of all 2019 patients of colorectal cancer admitted. Multivariate analysis demonstrated that CEA level before surgery、depth of invasion、 pathological type and Ducks' stage were the key risk factors predicting simultaneous liver metastasis from colorectal cancer. The survival rates at 1, 3 and 5 years were 69%, 21%, and 9% respectively. There was significant difference among the different liver metastasis group of H1, H2 and H3(X2=23.35, P<0.01). The survival rates of patients undergoing radical resection was higher than those undergoing palliative resection (PR)and by-pass operation or feeding neostomy(BP/ FN)(X2= 21.18,P<0.01). PR improved short-term prognosis but did not improve long-term survival compared with BP/FN group(P=0.13). Conclusion Colorectal cancer with synchronous liver metastases has poor clinic pathological characters. Different degree of liver metastasis result in different prognosis.Radical resection leads to a better prognosis. Palliative resection can improve short-term prognosis and life quality but can't improve long-term survival.
