尽管胃癌的诊治取得了长足的进步,但是仍有39%~65%进展期胃癌患者在根治术后出现复发,大部分在术后2年内复发[1~3]。由于缺乏预测根治术后复发风险、复发时间、复发形式的有效方法,而且复发性胃癌的处理非常棘手,手术切除率低、患者耐受性差、缺乏有效的延长生存期的治疗措施, Although considerable progress has been made in the diagnosis and treatment of gastric cancer, 39% to 65% of patients with advanced gastric cancer recurrence after radical operation, most of whom relapse within 2 years after surgery [1-3]. Due to the lack of an effective method of predicting the risk of recurrence after radical operation, the time of recurrence and the recurrent form, and the treatment of recurrent gastric cancer is very tricky, the rate of resection is low, the patients are poorly tolerated, and the effective treatment of prolonged survival is lacking.
