Is mTOR Pathway Activity a Good Predictor for Everolimus Therapy? A Pilot Study to Build Up a Phase II Trial in Pancreatic Neuroendocrine Neoplasias (pNENs)
Introduction: Everolimus (EVE) is an approved treatment for progressive well-differentiated pNENs and usually induces stable disease. Until now, there is no reliable biomarker for the response to EVE.
Aim(s): To study mTOR pathway activation as a new discriminator for EVE therapy.
Materials and methods: FFPE tumor material of 60 pNEN patients from 4 centers was macrodissected and RNA was extracted. Upregulation of 12 mTOR pathway signaling members was studied by TaqMan based RT-qPCR assays. Relative gene expression was determined according to the 40-DCT method using CALM2 as housekeeping gene.
