NCI - Cooperative Breast Cancer Tissue Resource (CBCTR)

The NCI Cooperative Breast Cancer Tissue Resource (CBCTR) can provide researchers with access to formalin-fixed, paraffin-embedded primary breast cancer specimens, with associated pathologic, clinical, and outcome data. All specimens are evaluated for pathologic diagnosis by CBCTR pathologists using standard diagnostic criteria. The collection is particularly well suited for validation studies of diagnostic and prognostic markers. The CBCTR also makes available breast cancer tissue microarrays designed by NCI statisticians to provide high statistical power for studies of stage-specific markers of breast cancer.
