#4667 Clinical outcomes in patients with typical (TC) and atypical bronchial carcinoids (AC): A 15-year retrospective study from an ENETS Center of Excellence

Introduction: Bronchial neuroendocrine neoplasms (NENs) can be subdivided into TCs, ACs and neuroendocrine carcinomas (NECs). Although a few studies have explored treatment approaches and oncological outcomes, most focus on surgical cohorts, small sample sizes, or mixed groups including TC, AC, and NECs. Real-life cohort data are lacking.

#4650 Whole exome sequencing in pulmonary neuroendocrine neoplasms: Findings from a pilot investigation

Introduction: The molecular landscape of lung neuroendocrine tumours (NETs) is still poorly characterised. Lung NETs main prognostic factors currently include stage, histotype, grade, location, and demographic parameters, but molecular biomarkers are still not available, limiting the possibility for personalised therapeutic strategies.

#4645 Radio-guided surgery in use for treatment of early relapse in small intestine neuroendocrine tumours

Introduction: Surgery is the only definitive therapy for neuroendocrine tumours (NET). In number of small intestine NET first symptom is ileus or perforation, lifesaving surgical procedures applied. Such cases have significant risk of recurrence.

#4642 Establishing a standardised histopathological grading system for mesenteric fibrosis in small intestinal neuroendocrine tumours

Introduction: Mesenteric fibrosis (MF) frequently develops around mesenteric metastasis in small intestinal neuroendocrine tumour (SI-NET) patients. Since MF is not always detected radiologically, histopathological examination is considered the gold standard. However, there is no uniform histopathological scoring system for MF correlated with clinical data.
