Association of poor prognosis with loss of 12q, 17p, and 18q, and concordant loss of 6q/17p and 12q/18q in human pancreatic ductal adenocarcinoma

Abstract

Because LOH of 12q, 17p, and 18q are significantly associated with a poor prognosis, mutation of the putative tumor suppressor genes on these chromosome arms may play significant roles in the disease progression. Concordant losses of 6q with 17p and of 12q with 18q suggest that protein products of putative tumor suppressor genes on 6q and 12q may function in association with TP53 and SMAD4, respectively.
