Acta Oncol. 2021 Jul;60(7):931-941. doi: 10.1080/0284186X.2021.1921262. Epub 2021 May 17.


Background: The diagnostic work-up and treatment of patients with gastroenteropancreatic (GEP) neuroendocrine neoplasms (NEN) has undergone major advances and new methods are introduced. Furthermore, an update of the WHO classification has resulted in a new nomenclature for GEP-NEN that is implemented in the clinic.

Aim: These Nordic guidelines summarise the Nordic Neuroendocrine Tumour Group's current view on how to diagnose and treat GEP-NEN patients and aims to be useful in the daily practice for clinicians.

Keywords: ;; Diagnosis; neuroendocrine carcinoma; neuroendocrine tumour; treatment.
