<qa>  What is the name of the NETs that are included in the SwissNET?All NETs of both, gastrointestinal and pulmonary origin are included provided that patients have given informed consent. Data will be entered prospectively and anonymised in a specifically designed database. Contributing centres and general practitioners are visited by a study nurse, patient files are analysed and data is transferred to the database. In case of conflicting evidence, questions are resolved in collaboration with a review board of SwissNET. Evaluation of treatment modalities and patient outcomes e.g. mortality, hospitalisation rate will take place within regular time frames.
