Biobanks

We initially consider 15 international cancer biobanks⁹⁶ in addition to 3 U.S. biorepositories and 1 published data from the Komen Tissue Bank⁹⁷ (also from U.S.). Since only biobanks that provide public data access⁹⁶ were selected for this study, 15 biobanks were excluded from our analysis: Australasian Biospecimen Network (Australia), Australian Prostate Cancer BioResource, BancoADN (Spain), Canadian Tumor Repository Network, Centro National de Investigationes Oncologicas Tumor Bank Network (Spain), Chernobyl Thyroid Tissue Bank (Russian Federation), Confederation of Cancer Biobanks (UK), Cooperative Human Tissue Network (USA), Kathleen Cuningham Consortium for Research into Familial Breast Cancer (kConfab; Australia), onCore UK (UK), Singapore Tissue Network, European Human Tumor Frozen Tissue Bank, UK Biobank, Victorian Cancer Research Tissue Bank (Australia) and Wales Cancer Bank. Thus, we studied race/ethnicity of all samples available at the TARP repository (n = 1,203), the Penn-CHOP Tumor Tissue Bank (n = 1,815) and the Children’s Brain Tumor Tissue Consortium (CBTTC) (n = 2,302). We also included recent data from the Komen Tissue Bank (n = 2,973), which harbors normal breast tissue for cancer research⁹⁷. Racial/ethnic data from TARP biorepository was obtained at https://ccrod.cancer.gov/confluence/display/CCRTARP/Home. Racial/ethnic information of The Penn-CHOP Tumor Tissue Bank and the CBTTC were obtained through the Biorepository Portal Toolkit².
