Conservative treatment of 35 patients with rectal cancer by local excision is reported. Limited surgery of rectal cancer can be a part of treatment of this tumor. Selection of the patient for limited surgical procedure should be strictly in accordance with the following criteria: tumor diameter less than 3 cm, clinical staging I and II, histologically well differentiated type, tumor invasion no deeper than the submucosa and patients with severe cardiopulmonary diseases who could not withstand radical surgery. A transanal local excision is the most straightforward approach. Local excision was by per anal full-thickness disc excision and trans-sphincteric disc excision. Prognosis and further treatment were based on the histopathologic results of operative specimen. The overall 5-year survival rate was 71.4% (18/21) and 10-year survival rate 33% (7/21).
报告了35例直肠癌患者采用局部切除的保守治疗情况。直肠癌的有限手术可以是该肿瘤治疗的一部分。选择患者进行有限手术应严格符合以下标准：肿瘤直径小于3厘米、临床分期为I期和II期、组织学上为高分化类型、肿瘤浸润不超过黏膜下层以及患有无法耐受根治性手术的严重心肺疾病的患者。经肛门局部切除是最直接的方法。局部切除采用经肛门全层盘状切除和经括约肌盘状切除。预后和进一步治疗基于手术标本的组织病理学结果。总体5年生存率为71.4%（18/21），10年生存率为33%（7/21）。
