Comparative genomic hybridization analysis of genetic aberrations associated with development and progression of biliary tract carcinomas

Abstract

It is likely that loss of 9p is one of the genetic aberrations critical for the development of biliary tract carcinoma, whereas gains of 5p, 7p, 7q, and 19q and loss of 6q are considered later events associated with tumor progression and are thought to confer metastatic potential to biliary tract carcinomas.
