#3058 Diagnosis and Assessment of Effectiveness of Surgical Resection of Small Bowel Neuroendocrine Tumours: The Roles of Circulating MicroRNAs

Introduction: MicroRNAs (miRNA) are small noncoding RNA molecules implicated in the pathophysiology of myriad neoplasms. Clinically useful biomarkers are needed in SB NET to ascertain disease aggressiveness, select treatment strategy, detect early recurrence and monitor response.

#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.

#3015 Biopsy Specimen Diagnosis in Pulmonary Carcinoids, A Shot in the Dark

Introduction: Pulmonary carcinoids (PCs) are rare well-differentiated neuroendocrine tumors, which can be separated into typical carcinoid (TC) and atypical carcinoid (AC). Advised treatment for local carcinoid disease is surgical resection using lobectomy, while parenchymal saving strategies such as sub-lobar or endobronchial resection might be considered for TC. In general, pre-operative diagnosis using a (transbronchial/transthoracic) biopsy sample is performed to demonstrate malignancy. However, TC and AC classification can solely be performed on surgical resection specimens, which may challenge pre-operative treatment decisions.

#3006 Teratoma with Malignant Transformation: A Case Report of a Neuroendocrine Tumor That Arises from the Bronchial Mucosa in a Mature Cystic Teratoma

Introduction: Mature cystic teratoma (MCT) is the most common type of germ cell tumor in the ovary. A malignant tumor that arises in a pre-existing mature teratoma is called teratoma with malignant transformation (TMT).

#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.
