局部切除治疗早期直肠癌

Local Excision of Early Stage Rectal Cancer

１９８４年９月～１９９４年９月，作者应用局部切除术治疗组织学特征良好的Ｔ＿１～Ｔ２Ｎ０Ｍ０期直肠癌２４例，结果５年无瘤存活率和局部控制率均为９５．８％。１例早期病例于术后１年半局部复发，无手术死亡及并发症。我们认为对癌细胞高度或中度分化，无淋巴管或静脉受侵犯，距肛缘１１ｃｍ之内，局限于粘膜或粘膜下层，或侵犯到肌层但未穿透肌层者均可行局部切除术。

From September 1984 to September 1994,twenty-four rectal cancer patients with good histologic characteristics (T1～T2N0M0) were performed by local excision. The results showed that 5-year tumor-free suvival rate and local control rate were 95.80% and 95.80% respectively. Only one early case developed local recurrence after primary operation one and half years later. There were no operation deaths and complications among these cases. We think that all patients with well to moderately histologic differentiation,with no lymph or blood vessel invasions and with turners within 11cm of the anal verge,within mucosa or submucosa,or invading into muscularis but not infiltrating muscularic could undergo local excision.
