Abstract:Objective:To investigate the rational method of treatment of rectal carcinoid and its outcome. Methods:The clinical data of 36 cases of rectal carcinoid were retrospectively analysed. Results:During a follow-up of 82.6+/-63.4 months, there were no cases with recurrence among the 20 patients with tumor size<1cm, 3 cases with recurrence in the 9 patients with tumor size between 1 to 2 cm, and there were 3 cases who died from liver metastasis among the 7 patients with tumor size>2cm .Conclusions:Tumor diametar can be used to estimate the degree of malignancy of rectal carcinoid. TNM staging is simpler and practical for deciding the method of surgical treatment.
