Trans-Anal Minimally Invasive Surgery (TAMIS) for Completion Local Excision of Well-Differentiated Rectal Neuroendocrine Tumours. Abstract #1716

Introduction: Rectal NETs (R-NETs) <2cm are often amenable to endoscopic resection, but initial resections are often incomplete, and extended monitoring or radical surgery may then be required. Trans-anal minimally invasive surgery (TAMIS) allows resection of rectal tumours while reducing surgical morbidity. Data on its use in R-NETs is scant.
Aim(s): To assess the results of TAMIS for completion local excision of R-NETs following endoscopic resection.
Materials and methods: We reviewed patients undergoing TAMIS for NET at our institution (2013-2016). Included patients had incomplete endoscopic resection (margin ≤1mm), a visible scar on repeat endoscopy, and localized disease on systemic imaging. Full-thickness resection of the endoscopic scar was performed. Outcomes were 30-day major morbidity (Clavien-Dindo III-V), resection margin, and oncological outcomes.

#160 The role of T-type calcium channels in medullary thyroid carcinoma (MTC): T-type calcium channel blockers inhibit hormone secretion and induce apoptotic cell death in a human MTC cell line
Introduction: Medullary thyroid carcinoma (MTC) accounts for approximately 5-10% of thyroid cancers. In the case of tumors limited to the thyroid gland, the prognosis is generally favorable, whereas 5-year survival averages only 40% in patients with metastatic disease. In these patients, conventional chemotherapy only occasionally leads to a complete response and partial responses are observed in less than 30% of the cases. Therefore, intense efforts are currently directed toward the identification of new druggable targets for the treatment of this devastating disease.
