#3988 Management and surveillance for rectal neuroendocrine tumors: A single-centre retrospective analysis and comparison with ENETS guidelines

Introduction: Rectal neuroendocrine tumors (rNETs) are rare but are increasing in incidence. Current management and surveillance recommendations are primarily based on low-grade evidence.

#3828 Role of endoscopic resection margin (R1) in the clinical outcome of patients with neuroendocrine neoplasia

Introduction: Endoscopic resection margin R1 (ER1) describes neoplasia presence at lateral and/or deep margin. Highest rate of R1 resection occurs in duodenal NENs (d-NENs) where advanced resection techniques [endoscopic submucosal dissection (ESD); full thickness resection (EFTR)], are more difficult to apply. In gastric (g-NENs) and rectal NENs (r-NENs), due to favourable anatomy, ESD or EFTR obtain lower rates of R1 resection.

#3029 Adrenocortical Carcinoma Metastasic in Adult on Complete Response with EDP-M and Local Therapy: A Single Case Report

Introduction: Adrenocortical carcinoma (ACC) in adults is a rare tumor (incidence 0.7-2/1000000/year). Median overall survival is 3-4 years and five-year survival is 0-28% in metastatic disease. The only curative therapy is complete surgical resection, plus adjuvant therapy depending on poor prognostic factors (ENSAT stage III, R1 resection or Ki67>10%). Both recurrent oligometastatic disease and patients who respond to systemic treatment (ST), a radical approach with surgery or local therapy (LT) may be treatment options.

#2273 The Clinical Value of Circulating Transcript Analysis (NETest) during Follow-Up of Resected Well-Differentiated Pancreatic Neuroendocrine Tumors

Introduction: Follow-up after resection of pancreatic neuroendocrine tumors (pNET) is designed to detect recurrence early, as incidence is reported up to 48%.
