The NCI Cancer Imaging Program organized those CPTAC specific cases as an opportunity for researchers to explore what such combined research resources might offer. They consist of 28 ovarian (TCGA-OV) and 14 breast (TCGA-BRCA) cases. Those imaging cases are easily downloadable as tumor specific groups from TCIA using the drop-down Tool-menu entry “shared lists” by under the separate titlesnames of: "CPTAC BreastAnalyzed, " and "CPTAC OV Analyzed. Those image ". The images of those grouped cases can be down-loaded by entering the afore-mentioned “shared lists” names on https://public.cancerimagingarchive.net/ncia/searchCustomList.jsf Their individual case-matched CPTAC Proteomic Analysis Data is down-loadable from: https://cptac-data-portal.georgetown.edu/cptacPublic/ Moreover, the case specific Clinical Data that matches each of those TCIA archived image cases are attached here as XLS sheets.
