Whole Exome Sequencing Reveals the Monoclonal Origin of Gastric Mixed Adenoneuroendocrine Carcinomas


Introduction: Gastric mixed adenoneuroendocrine carcinomas (g-MANECs) are rare neoplasms consisting of adenocarcinoma and neuroendocrine neoplastic components. G-MANECs show more malignant characteristics than gastric adenocarcinomas, while molecular mechanisms underlying the co-existence of the two components remains unknown.

Aim(s): The study aims to investigate the origin and evolution of g-MANECs using whole exome sequencing analyses.

Materials and methods: The adenocarcinoma and neuroendocrine components from 20 patients with g-MANECs were microdissected and the whole exome sequencing analyses of the two components were performed separately.
