#3090 Retrospective Experience with Pherochromocytoma (PH) and Paraganglioma (PG) in a Single Argentinian Institution

Introduction: Pherochromocytoma (PH) and paraganglioma (PG) are neuroendocrine tumors arising in cromaffin cells in the adrenal medulla or extra adrenal paraganglia respectively. Clinical presentation is diverse. All PG/PH have malignant potential. Hereditary cases comprise up to 40% of all PG/PH.

#2961 Our Experience Using a New Scoring System to Detect Disease Recurrence after Curative Surgical Resection of Well-Differentiated Pancreatic Neuroendocrine Tumors

Introduction: For patients with nonfunctioning pNET  ≥20 mm in size without distant metastasis, complete surgical resection is recommended as the primary curative strategy. Effective follow‐up programs are designed to detect recurrence at an early stage, given that treatment of limited disease has the most favorable outcome. However, data on post‐curative surgical recurrence remains limited, making it challenging to determine the best follow‐up strategy and to detect the best treatment options as an adjuvant therapy for selected patients.

#2816 Germline Variants in Cancer Predisposing Genes in Young Adults with Neuroendocrine Tumors

Introduction: Advances in genomics have enabled the recognition of new cancer predisposing genes (CPG). There are few studies of CPG in neuroendocrine tumors (NET).

#2813 Clinical Presentation and Prognosis of Patients with Medullary Thyroid Cancer

Introduction: Medullary thyroid carcinoma (MTC) is a rare type of tumor that originates from parafollicular C-cells and accounts for 3–4% of all malignant thyroid neoplasms. MTC presents as sporadic (75–80%) or inherited tumors (20–25%). Hereditary MTC is part of multiple endocrine neoplasia type 2 (MEN2).

#2276 Ki-67 to Predict Recurrence and Survival of Pancreatic Neuroendocrine Tumors

Introduction: Despite evidence of different malignant potential, postoperative follow-up is similar for G1 and G2 pancreatic neuroendocrine tumors (panNET) and adjuvant treatment is currently not indicated.
