#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.

#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.

#2899 Using Long-Acting Somatostatin Analogue as Adjuvant Therapy for Post Resection Grade 2 Pancreatic Neuroendocrine Tumor: Interim Results from an Ongoing Multicenter Real-World Study in China

Introduction: Surgery was the preferred treatment in patients with resectable pancreatic neuroendocrine tumor (pNET), but recurrent lesion relapsed frequently within a short time. It was controversial whether patients with pNET need adjuvant therapy after surgery.

#2856 Pattern of Disease Recurrence and Treatment after Radical Surgery for Nonfunctioning Pancreatic Neuroendocrine Tumors (NF-PanNET)

Introduction: The risk of recurrence after radical surgery performed for pancreatic neuroendocrine tumors (PanNET) is reported between 10 and 30%. Nowadays, no adjuvant therapy is recommended for these patients and specific treatments are offered only when recurrence occurs. Nevertheless, among the available systemic and locoregional treatments, there are no specific recommendations on which the best option could be for treating recurrent disease.

#1674 Meta-Analysis of Recurrence after Curative Surgery of Pancreatic Neuroendocrine Tumors.

Introduction: Follow-up after curative surgery for pancreatic neuroendocrine tumors (pNET) is designed to detect recurrence, however reliable recurrence rates are difficult to deduct from literature. Without this knowledge, appropriate follow-up regimens and indications for adjuvant treatment remain unclear.
