Pancreatic neuroendocrine neoplasms (pNENs) represent approximately 2% of all solid pancreatic tumors. The incidence of pNENs has been increasing in the last decade. The clinical manifestations of pNENs range from hormone secretion syndromes in functioning neoplasms (F-pNENs) to local infiltration or distant metastases in late-stage diagnoses or incidental findings in small non-functioning neoplasms (NF-pNENs). While surgery is the gold-standard treatment for larger and more aggressive tumors, small and low-grade tumors (G1) may be followed-up due to the indolent course of disease. Recently, endoscopic ultrasound (EUS)-guided ablative techniques, such as ethanol injection (EUS-EI) and radiofrequency ablation (EUS-RFA), have emerged as promising options for loco-regional ablations in selected cases. Despite promising safety profile and efficacy, high-quality evidence is needed to support their widespread adoption. This article reviews the current state of EUS-guided locoregional therapies, patient selection criteria, procedural details, and associated risks.

The von Hippel-Lindau (VHL) tumor suppressor gene VHL is a classic tumor suppressor that has been identified in family members with clear cell renal cell carcinomas, central nervous system and retinal hemangioblastomas, phaeochromocytomas, and pancreatic neuroendocrine tumors. The well-defined function of VHL is to mediate proteasomal degradation of hydroxylated hypoxia-inducible factor α proteins, resulting in the downregulation of hypoxia-responsive gene expression. Previously, we reported that VHL inhibits antiviral signaling by targeting mitochondrial antiviral signaling protein (MAVS) for proteasomal degradation.

Pancreatic panniculitis (PP) and arthritis may be extrapancreatic manifestations of pancreatic disease. The triad of pancreatic disease, panniculitis and polyarthritis, described in the literature as the PPP syndrome, is sometimes observed in patients with acute or chronic pancreatitis, pancreatic cancer or neuroendocrine tumors (NETs). We present a 60-year-old man with polyarthritis and clinically aggressive PP of the limbs.

Introduction: Multiple endocrine neoplasia type 1 (MEN1) syndrome is characterized by presenting different pathologies with different degrees of tumor aggressiveness, which can greatly affect the quality of life of affected patients.
Objectives: To determine the quality of life of MEN1 patients and to analyze the influence of socio-personal, clinical, and therapeutic variables.
Methods: A study was conducted on MEN1 patients in a tertiary hospital [2018-2020].

Background & Objective: Limited literature describes the accuracy of endoscopic ultrasonography-fine needle aspiration (EUS-FNA) cytology in various types of pancreatic epithelial tumors, and this underscores the usefulness of cell blocks, and highlights potential diagnostic pitfalls.
Methods: This study included 108 patients who underwent EUS-FNA pancreatobiliary cytology followed by surgery. Age, gender, tumor location, tumor size, presence or absence of a cell block, cytologic and pathologic diagnoses, and histologic tumor grade were recorded.

Background: Although, recently observation methods has been proposed as one of the treatment options for non-functioning pancreatic neuroendocrine neoplasms (NF-PanNENs), determining treatment strategies may be difficult for small and low-malignant NF-PanNENs; thus, clarifying the significance of lymphatic, microvascular, and perineural invasion in these patients is of great clinical importance. This study aimed to assess the incidence and role of lymphatic, microvascular, and perineural invasion in patients with NF-PanNENs based on tumor size and the 2022 World Health Organization classification.
Methods: From 2000 to 2023, we retrospectively investigated the incidence of lymphatic, microvascular, and perineural invasion and their impact on recurrence in 80 patients who underwent curative resection and were diagnosed with NF-PanNENs.
