Contrary to other cancer types, histopathology remains the mainstay of diagnosis and classification of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs). Increasing knowledge of the molecular genetics and biology of GEP-NENs promises to improve classification of disease subtypes, and thus the management of the disease. Herein, the authors discuss the features of GEP-NENs that, as prognostic or predictive biomarkers, could form the basis for a novel, clinically useful molecular classification system.
