英国学者近期发表于《英国外科杂志》(British Journal of Surgery)的一项荟萃分析表明,关于结直肠癌肝转移肝切除术后随访研究的资料很少,早期强化随访未被发现可增加患者生存益处。
研究者系统回顾了2003年1月~2010年3月发表的文献,并进行了相关的研究分析。
结果显示,共有35项研究(包含7330例患者)被纳入分析,仅5项有专门的随访数据。
接受早期强化随访的患者中位生存期为39.8个月,5年总生存率为41.9%。
接受常规随访的患者中位生存期为40.2个月,5年总生存率为38.4%。

The evidence surrounding optimal follow-up after liver resection for colorectal metastases remains unclear. A significant proportion of recurrences occur in the early postoperative period, and some groups advocate more intensive review at this time.
A systematic review of literature published between January 2003 and May 2010 was performed. Studies that described potentially curative primary resection of colorectal liver metastases that involved a defined follow-up protocol and long-term survival data were included. For meta-analysis, studies were grouped into intensive (more frequent review in the first 5 years after resection) and uniform (same throughout) follow-up.
Thirty-five studies were identified that met the inclusion criteria, involving 7330 patients. Only five specifically addressed follow-up. Patients undergoing intensive early follow-up had a median survival of 39·8 (95 per cent confidence interval 34·3 to 45·3) months with a 5-year overall survival rate of 41·9 (34·4 to 49·4) per cent. Patients undergoing routine follow-up had a median survival of 40·2 (33·4 to 47·0) months, with a 5-year overall survival rate of 38·4 (32·6 to 44·3) months.
Evidence regarding follow-up after liver resection is poor. Meta-analysis failed to identify a survival advantage for intensive early follow-up.
