直肠癌同时性肝转移同期切除与分期切除比较*

目的:比较直肠癌同时性肝转移患者同期切除与分期切除安全性及远期疗效。方法:收集从2000年1 月至2015年4月北京大学肿瘤医院行手术切除的54例直肠癌同时性肝转移患者的临床病理及围手术期资料，并随访其复发及生存状况，比较同期切除组（19例）及分期切除组（35例）的安全性及远期疗效。结果:两组患者临床病理资料基本一致。同期切除组及分期切除组术后Clavien-Dindo 1 级、2 级、3 级及4 级并发症的发生率分别为10.5%（2/ 19）、31.6%（6/ 19）、5.3%（1/ 19）及10.5%（2/ 19）和8.6%（3/ 35）、17.1%（6/ 35）、25.7%（9/ 35）及0（0/ 35）；差异无统计学意义（P = 0.093）。 但术后中位住院时间同期组明显低于分期组（同期组14d，分期组25d，P < 0.001）。 同期组与分期组术后中位生存期差异无统计学意义（同期组未达到，分期组39个月，P = 0.649），两组术后无病生存期差异无统计学意义（同期组10个月，分期组10个月，P = 0.827）。 结论:直肠癌同时性肝转移患者同期切除与分期切除比较未明显增加患者围手术期并发症，而且远期疗效相似。 

Simultaneous versus staged resection for synchronous rectal cancer liver metastasis

Objective:To compare the safety and long-term survival of patients with synchronous rectal cancer liver metastasis, who received either simultaneous or staged resection to treat primary tumor and liver metastases.Methods:Clinicopathologic and peri -operative data were collected retrospectively from54patients with synchronous rectal cancer liver metastasis, who received both prima -ry and liver resections between January 2000and April 2015at Peking University Cancer Hospital. Routine follow-up was conducted. The safety and long-term survival of19patients who underwent simultaneous resection were compared with those of 35patients who received staged resection. Results: The clinicopathologic data between the two groups were comparable. Postoperative Clavien-Dindo grades 1, 2, 3, and 4 complications were 10.5% (2/19), 31.6% (6/19), 5.3% (1/19), and 10.5% (2/19) for the simultaneous group, respec -tively, and 8.6% (3/35), 17.1% (6/35), 25.7% (9/35), and 0% (0/35) for the staged group correspondingly, which were not significantly different (P=0.093). However, the median postoperative hospital stay of the simultaneous group was significantly shorter than that of the staged group (14days versus 25days,P<0.001). The median postoperative overall survival (OS) and disease-free survival (DFS) be-tween these groups were not significantly different not reached versus 39months for OS, respectively ( P=0.649); 10months versus 10 months for DFS, respectively (P=0.827)]. Conclusion:The postoperative complications in simultaneous resection group were not sig -nificantly increased compared with those in staged resection group for synchronous rectal cancer liver metastasis. The long-term results among the groups were similar.
