Cancers of the distal rectum (less than 7.5 cm from the anal verge) that are freely mobile, moderately well or well differentiated, less than 4 cm in size, limited to the bowel wall, and without evidence of metastasis should be considered candidates for treatment with electrocoagulation for cure. Tumor cell ploidy and evaluation with intrarectal ultrasound may in the future add additional useful information with regard to patient selection. Electrocoagulation and laser ablation of tumors may also be useful modalities for palliation of patients with metastatic disease or who are not candidates for curative surgery.
距肛缘小于7.5厘米的直肠远端癌，若活动自如、中度分化良好或分化良好、大小小于4厘米、局限于肠壁且无转移证据，则应被视为可采用电凝术进行根治性治疗的候选对象。肿瘤细胞倍体分析和直肠内超声评估未来可能会为患者选择提供更多有用信息。对于转移性疾病患者或不适合进行根治性手术的患者，肿瘤的电凝术和激光消融术也可能是有效的姑息治疗方式。
