In this prospective study the aim is to obtain fresh tumor biopsies and three blood samples from patients with a confirmed histological or cytological diagnosis of well-differentiated neuroendocrine tumors (NETs) or well-differentiated pancreatic neuroendocrine tumors (PanNETs). Eligible population includes: NETs and PanNETs patients who have undergone or are undergoing treatment with targeted therapies and have shown prolonged clinical benefit, and NETs and PanNETs patients who have been treated with these agents and just recently progressed. RNA and DNA from fresh tumor biopsies and from mononuclear blood cells will be subjected to transcriptome sequencing and DNA sequencing analyses to evaluate possible genes of interest and related targetable pathways. Moreover, archived tumor samples will be requested from all patients to perform additional genomic testing. Remaining RNA and DNA will be banked for additional exploratory analyses (e.g. further genomic testing, or DNA copy number analysis, or epigenetic evaluations).
