本文回顾分析经根治性手术切除的154例T_1,T_2期直肠癌病理特征,并对淋巴结转移(LNM)作出预测。男99例,女55例;平均年龄62岁(21～88岁)。经腹会阴切除者62例;低位前切除者92例。肿瘤下缘距肛门2～6cm者79例;7～11cm者74例。肿瘤限于粘膜、粘膜下层26例(T_1);侵入肌层128例(T_2)。以外生为主,蕈伞状者为外生型;肿瘤边缘隆起变硬为息肉型;息肉隆起型或无蒂病变为无蒂型。无粘液池者为单纯腺癌。1
This article reviews the pathological features of 154 T_1, T_2 rectal cancers treated by radical surgery and predicts lymph node metastasis (LNM). There were 99 males and 55 females; the average age was 62 years (21-88 years old). Abdominal perineal resection was performed in 62 cases; low resection was performed in 92 cases. Twenty-nine patients with 2 to 6 cm of anal distance from the lower edge of the tumor and 74 patients with 7 to 11 cm. Tumors were confined to the mucosa and submucosa in 26 cases (T 1 ); invasive muscles were found in 128 cases (T 2 ). Exogenous mainly, paralysis umbrella is exogenous; tumor edge uplift hardened polyps; polyp uplift or sessile lesions are pedicled. The inviscid pool was pure adenocarcinoma. 1
