Colorectal cancers treated for cure by operative means show tumour recurrences and metastases in about 20% of the patients. Of these colon or rectal cancers 75 and 90% respectively can be only operated for palliation. These patients have a better prognosis than those operated primarily for palliation. 25% of the cases especially with suture line recurrences can be operated upon radically enough and exhibit a total five year survival rate of 50%.
通过手术方式进行根治性治疗的结直肠癌患者中，约20%会出现肿瘤复发和转移。在这些结肠癌和直肠癌患者中，分别有75%和90%只能进行姑息性手术。这些患者的预后比那些一开始就进行姑息性手术的患者要好。25%的病例，尤其是缝线部位复发的病例，可以进行足够彻底的根治性手术，其五年总生存率为50%。
