Core Tip
Core tip: Patients with gastroenteropancreatic neuroendocrine tumours (GEP-NETs) often experience diarrhoea, which may have multiple synchronous causes. Although this has a considerable impact on patient quality of life, differential diagnosis of diarrhoea in patients with GEP-NETs is a relatively unexplored topic, and there is currently no formal clinical guidance. This systematic literature review provides valuable insight on the prevalence of causes of diarrhoea in patients with GEP-NETs, evidence on how these cause are diagnosed in this patient population specifically, the consequences if the true cause(s) of diarrhoea are not ascertained, and suggestions for improving differential diagnosis of GEP-NET diarrhoea.
