We investigated the treatment of 24 rectal carcinoid tumors from both the clinicopathologic and prognostic viewpoints. All tumors less than 2 cm in diameter had neither muscle layer invasion nor lymph node metastasis, except for an atypical carcinoid tumor that had both lymphatic permeation and intramural metastasis. One typical carcinoid tumor larger than 2 cm had both several lymphatic permeations and urinary bladder invasion. All cases had a good prognosis with no recurrence and no new metastases. For rectal carcinoid tumors less than 2 cm in diameter, local resection is sufficient, whereas radical operation is required for tumors larger than 2 cm in diameter. For atypical rectal carcinoid tumors, radical operation should be considered even if the diameter is less than 2 cm.
我们从临床病理和预后的角度对24例直肠类癌肿瘤的治疗进行了研究。所有直径小于2 cm的肿瘤均无肌层浸润和淋巴结转移，但有1例非典型类癌肿瘤存在淋巴管浸润和壁内转移。1例直径大于2 cm的典型类癌肿瘤有多处淋巴管浸润及膀胱侵犯。所有病例预后良好，无复发及新的转移。对于直径小于2 cm的直肠类癌肿瘤，局部切除即可，而直径大于2 cm的肿瘤则需要根治性手术。对于非典型直肠类癌肿瘤，即使直径小于2 cm也应考虑行根治性手术。
