The aim of our research was to analyze if there is a subtype of pancreatic cancer patients based on detailed molecular profile available in clinical settings, which would benefit from MEK inhibitors in monotherapy or in combination with other targeted therapies in clinical trials or off label indications, and to provide scientific rationale to initiate new trials with MEK inhibitors in specific molecular subtypes of pancreatic cancers. The gene discussed is MAP2K7; the disease is familial pancreatic carcinoma.
