ENETS Consensus Recommendations for the Standards of Care in Neuroendocrine Neoplasms:Follow-Up and Documentation

ENETS consensus recommendations for the standards of care in neuroendocrine neoplasms (NEN) concerning follow-up and documentation are considered in this review. The documentation of patients with NEN should include the most relevant data characterizing an individual patient from the first contact with his/her physician/hospital until his/her last presentation during follow-up. It is advocated that follow-up occurs in specialized NEN centers with regular NEN tumor boards with expert panels. The follow-up should be in accordance with the ENETS consensus guidelines from 2011 and 2016, the present and coming WHO classification and ENETS/UICC recommendations for TNM staging. The recommendations for follow-up in patients with thymic, bronchopulmonary and gastroenteropancreatic NEN are given in Table 1. However, it should be stressed that evidence-based studies for follow-up are largely missing.
