摘要 结直肠癌确诊时约20%~25%的患者合并远处转移。转移灶及原发灶的R0切除是Ⅳ期转移性结直肠癌(metastatic colorectal cancer,m CRC)患者获得长期生存的基础。但对于转移灶不可切除的Ⅳ期m CRC,其原发灶是否手术及手术时机一直存在较大争议。对于合并肠梗阻、大出血、穿孔或即将发生肠梗阻等急性并发症的Ⅳ期m CRC患者,施行急诊或限期手术处理原发灶以缓解局部症状是必须的;但是对于原发灶无症状或仅有轻微症状者,是否手术及手术时机尚缺乏统一意见,“手术派”认为,Ⅳ期m CRC患者迟早会发生肠梗阻、穿孔、出血等并发症,主张预防性切除原发灶;“观察派”则认为,Ⅳ期m CRC患者预期生存时间短,预防性切除原发灶的手术相关风险高,总体收益弊大于利,主张治疗以化疗为主,待原发灶出现明显局部症状时再行手术。
