Pancreatic Neuroendocrine Neoplasms and GastroIntestinal Stromal Tumours: A Single-Institution Experience of a Rare Association and Review of the Literature

#2911

Introduction: Pancreatic neuroendocrine neoplasms (pNENs) and gastrointestinal stromal tumours (GISTs) are both rare neoplasms, and they have an estimated incidence of about 1/100,000 per year and about 1-1.5/100,000 per year, respectively.

Aim(s): To evaluate non-syndromic cases of pNENs associated with a synchronous GIST, and to perform a review of the literature on this uncommon association.

Materials and methods: We evaluated clinic-pathological features, post-operative outcome and follow-up of patients who underwent surgery for non-syndromic synchronous pNENs and GISTs in our unit (2003-2017).
