大肠类癌临床特点及微创治疗

Clinical characteristics of colorectal carcinoid and minimally invasive therapy

目的 :探讨大肠类癌的临床特点及治疗手段。方法 :回顾性分析 32例大肠类癌临床资料。结果 :大肠类癌男女之比为 3∶1 ;直肠类癌发病率高 ,肿瘤直径 <2 0mm者微创治疗预后较好 ;肿瘤直径 >2 0mm的大肠类癌转移率高 ,即使扩大切除 ,预后也很差。结论 :大肠类癌的大小 ,有无肌层浸润 ,是决定手术方式主要依据 ,类癌<2 0mm可采用微创治疗 ,类癌 >2

Objective: To investigate clinical characteristics and treatment methods for colorectal carcinoid. Methods: Clinical characteristics of 32 cases of colorectal carcinoid were analyzed retrospectively. Results: The male/female ratio was 3 to 1.Tumor was located in rectum in 84% of the cases. Small carcinoid tumors with diameter <20 mm which were treated locally had favorable clinical course without recurrence. In contrast, those with diameter >20 mm hade poor prognosis and high incidence of metastasis, even after extended surgery. Conclusion: Tumor size and depth of invasion are important for selecting operative modes. Cases of small carcinoid tumors with diameter <20 mm should receive minimally invasive therapy, and those with diameter >20 mm should receive extended surgery.
