The different ways of metastases of carcinoma of the anus can hardly be removed by radical surgery and require other procedures than the lower carcinoma of the rectum. In comparing Miles operation in T3/T4 carcinomas of the anus with the combined therapy of local excision and radiotherapy results showed no great difference in T1/T2 tumors the Miles operation is not necessary. In T3/T4 carcinomas irradiation derives its worth from the few possible procedures ro radical surgery. In T1/T2 tumors irradiation can be an alternative (T1) or an additional treatment (T2) to the local excision.
肛管癌的不同转移方式很难通过根治性手术切除,与直肠癌低位癌相比需要其他治疗手段。比较肛管T3/T4期癌的腹会阴联合切除术与局部切除加放疗的综合治疗效果,结果显示T1/T2期肿瘤二者差异不大,腹会阴联合切除术并非必要。在T3/T4期癌中,放疗的价值在于根治性手术的可能性较小。在T1/T2期肿瘤中,放疗可作为局部切除的替代治疗(T1)或辅助治疗(T2)。
