Oncoscan for HER2 copy number assessment

Affymetrix Oncoscan arrays were performed according to the manufacturer's directions on DNA extracted from FFPE-breast cancer tissues. Copy number analysis using Affymetrix Oncoscan arrays was performed for 29 primary breast cancers本研究按照生产商的操作指南，对从福尔马林固定石蜡包埋（FFPE）乳腺癌组织中提取的DNA开展Affymetrix Oncoscan基因芯片（Affymetrix Oncoscan arrays）检测。针对29例原发性乳腺癌样本，采用该基因芯片进行拷贝数分析。
