  "abstract": "Background\n\nPancreatic neuroendocrine tumors (PNETs) are rare neoplasms of the digestive system, with variable prognoses and biological behaviors. Surgical resection remains the mainstay of treatment. Objective: To evaluate the clinicopathological characteristics and surgical outcomes of patients with PNETs who underwent resection at the Hospital de Clínicas, UNICAMP.Methods\n\nThis is a retrospective cohort study including 24 patients who underwent surgical resection between 2013 and 2023. Clinical, demographic, histopathological, and survival data were analyzed. The primary outcome was overall survival.Results\n\nThe mean age was 53.9 ± 14.4 years, with a predominance of female patients (66.7%). Most tumors were nonfunctioning (79.1%), with abdominal pain (79.2%) and weight loss (50%) being the most common symptoms. The surgical procedures performed were distal pancreatectomy (54.2%), pancreaticoduodenectomy (41.6%), and enucleation (4.2%). Histological classification revealed 62.5% grade 2 tumors, 33.3% grade 1, and 4.2% MiNEN. Mean overall survival was 70.4 ± 58 months. There was a trend toward longer survival in grade 1 tumors (98 ± 68.1 months) compared to grade 2 (59.1 ± 49.5 months; P=0.06). Postoperative mortality was 8.3%, associated with pancreaticoduodenectomy.Conclusion\n\nHistological grading remains a key prognostic factor in PNETs. Surgical resection remains the cornerstone of treatment. Multicenter studies are necessary to validate these findings on a larger scale.",
