Genome-Wide Somatic Copy Number Alterations in Low-Grade PanINs and IPMNs from Individuals with a Family History of Pancreatic Cancer
Clinical Cancer Research, 07/17/2012
Hong SM et al. – Low– and intermediate–grade pancreatic intraepithelial neoplasias (PanIN) and intraductal papillary mucinous neoplasms (IPMN) from patients with a family history of pancreatic cancer harbor few if any somatic chromosomal alterations. The absence of a locus of recurrent chromosomal loss in most low–grade pancreatic cancer precursor lesions supports the hypothesis that there is no one tumor suppressor gene locus consistently involved in initiating familial pancreatic neoplasia.
