Breast cancer is a leading cause of morbidity and mortality among female cancer patients in China and the world [1].Although having yielded a great deal of knowledge in the last three decades,basic breast cancer research is often conducted using cultured cells that mimic tumors only to a certain extent.Likewise,the use of mouse models to investigate breast cancer has its obvious limitations.The combination of tumor samples and patients’ clinical information can facilitate the discovery of new biomarkers,which can be used to benefit new tumor patients.However,the acquisition and access to tumor specimens as well as comprehensive information on patients have been a bottleneck in breast cancer research.A comprehensive information database (CID) allows scientists to assess and verify the clinical relevance of basic findings,thereby providing an essential link between basic and applied research [2,3].The recent advances in genomics,proteomics,biotechnology,and information technology led to the establishment of many national tumor bank networks,such as the Spanish National Tumor Bank Network (SNTBN),which aims to collect tumor banks across Spain.
