We aim to evaluate patients’ expectations about the impact of peptide receptor radionuclide therapy (PRRT) on their health related quality of life (HRQol) and their actual quality of life QoL in patients with neuroendocrine tumors (NETs).. We will also be able to assess the quality of life in elderly patients, and those with multiple comorbidities (ECOG performance status at baseline between 0 to 2 ),when being treated with PRRT, as there are few studies evaluating the health related quality of life (HRQol) in these two subgroups.
