#1715 Recurrence of 6mm Rectal Neuroendocrine Tumor, 14 Years after Excision
Introduction: Rectal neuroendocrine tumours (NET) constitute 25% of all the digestive NET. Predictive factors of distant metastasis are: size greater than 1cm, high proliferative index and muscularis or lymphovascular invasion. In the absence of these criteria, some authors advocate there is no need for long-term follow-up.

#139 Association of carcinoid with noncarcinoid neoplasms
Introduction: Carcinoid tumors have a complex disease spectrum. Most have a benign clinical course, but some are aggressive, with invasive growth, metastasis and short survival. In carcinoid tumors, more than 20% are associated with noncarcinoid neoplasms. When the second tumor is a more malignant lesion, the prognosis usually is correlated more closely with the noncarcinoid malignant neoplasm.
