The aim of this study is to evaluate the financial toxicity reported by Italian patients affected by GEP-NEN during the first year of treatment after diagnosis and its correlations with patient-reported outcomes (PROs) and quality of life (QoL).

Gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) are rare tumours whose incidence has increased during the years. However, referral centers specialized in diagnosis and treatment of these diseases are few. So, patients may be forced to travel long distances in order to reach a disease specialized center (ENETS certification) to plan the correct management and receive the better treatment. On the other hand, patients could research different clinical consulting by several medical specialists without clear indication. Moreover, today also advanced disease allows the patients a good prognosis with long survival. The resulting emotional and psychological burden may contribute to the worse quality of life. Therefore, patients with GEP-NEN have a deal with the financial consequences related to the diagnosis and treatment of their disease including out of pocket costs, loss of income and caregiver burden. Financial toxicity, defined as subjective financial concerns of cancer and objective financial consequences, has been investigated in this study in Italian patients affected by GEP-NEN

• Signed informed consent

Exclusion Criteria:

• Patients diagnosed with GEP-NEN who are candidates for a surveillance management.
• Patients diagnosed with GEP-NEN who are candidates for best supportive care and/or have a life expectancy < 6 months.

This study enrolls individuals (>18 years) with a new diagnosis of GEP-NEN who are candidates for surgical and/or medical treatment, in Italian Centers. Are excluded from this study patients candidates for a surveillance management and, on the opposite side, with life expectancy < 6 months or candidates for best supportive care.
