Project description:167 Ull-samples 244k array Tumor tissue from a series of 212 primary breast cancers were sequentially collected at Ullevål University Hospital, Oslo, Norway between 1990 and 1994. Tissues were collected at the time of primary surgery and snap frozen. We performed aCGH on 167 of these samples. DNA was isolated using chloroform/phenol extraction, followed by ethanol precipitation. The aCGH-platform was the Agilent Human genome CGH Microarray 244k. The aim of this study was to investigate the genome wide genomic copy number alterations in a cohort of primary breast cancer patients.
