大肠癌约有半数在“根治性”切除后仍出现局部或远隔部位复发。约50％～80％发生于术后2年内,6～12个月为高峰,5年后罕见。复发的大肠癌再切除率为10％～20％,再次根治术后的5年生存率为20％～30％。术后监测在于发现尚能切除的复发肿瘤。1 监测方法1.1 病史 应注意询问发现腹部、盆腔、会阴部疼痛,大便习惯改变或便血、咳嗽、肝区痛以及体重、食欲、精神方面的改变等。
About half of colorectal cancers still have local or distant recurrences after “radical” resection. About 50% to 80% occurred within 2 years after surgery, peaking at 6 to 12 months, and rare after 5 years. The recurrence rate of recurrent colorectal cancer was 10% to 20%, and the 5-year survival rate after radical resection was 20% to 30%. Postoperative monitoring consists of the discovery of recurrent tumors that can still be resected. 1 Monitoring methods 1.1 Medical history Care should be taken to find abdominal, pelvic, perineal pain, changes in bowel habits or blood in the stool, cough, liver pain and weight, appetite, and mental changes.
