直肠神经内分泌肿瘤的诊断与治疗(附14例报告)OACSTPCD

Objective To analyze the diagnosis and treatment in rectal neuroendocrine tumor. Methods The clinical and pathological data of 14 cases with rectal neuroendocrine tumor were analyzed retrospectively. Results Tumor diameter was<1 cm in 8 cases,≥1 cm and<2 cm in 4 cases and that in other 2 cases was 2 cm and 3 cm respectively. The treat-ment for 12 cases with tumor<2 cm of diameter was transanal local resection in 3 cases and endoscopic mucosal resection in 9 cases. Low anterior resection was performed in 2 cases with tumor ≥2 cm of diameter. Thirteen patients were followed and all survived. Conclusions The results of our study showed that the biological behavior of rectal neruoendocrine tumor is low malignant potential. The lesions with<2 cm of diameter do not invade muscularis propria and rarely metastasize. Most of the patients could be cured by local resection including transanal local excision and endoscopic mucosal resection.
