Overview

This is a retrospective/prospective observational multicentric trial on patients with bone metastases from NENs. General objectives: * To trace on a national scale the frequency of bone metastases in patients with neuroendocrine neoplasm (NEN) and their clinical management. * To correlate clinical and biological factors to clinical outcomes. * To centralise and to make homogeneous clinical, pathological, instrumental and therapeutic information. * To set up a database and to acquire biological material for studying predictive and prognostic biomarkers.
