126例直肠癌淋巴结转移分析

施行扩大性根治术病例中近半数病变位于腹膜返折以下，其中半数病例有上方转移。腹膜返折上病变近三分之一有上方转移。全病例组淋巴结转移以２５１、２５２、２６１组占多数。本组尚有腹主动脉周围淋巴结转移。侧方转移病例中无１例因淋巴结转移而导致复发，可见扩大性根治术对预后的意义。此外，对必要的病例进行联合脏器清除术（男性盆腔内脏全切除，女性后盆腔内脏切除术）。及术后化疗是十分重要的。

A Study of Lymph Node Metastasis of the Rectal Cancer in 126 Patients

In the extended radical operation abroud half of the all patients cancer is belowtheperitoneal reflection. And in this patients a half have upper metastasis. Onethirdpatients have upper metastasis when cancer is above the peritoneal reflection.Incidence of lymph node metastasis of 251,252,261 node station is the best inthe all patients. This group more have the paraaorta lymphnode metastasis. The patients with lateral metastasis not the local recurrence becauce lymph node metastasis. According this exended radical operation is very important for the prognostic. The authors suggested that related patients have been pelvic exen-teration and post-operative medical therapy.
