The NCDB is a widely used resource for cancer research, including for radiology studies. However, the researchers noted that the current state of representation of different racial and ethnic groups compared with the United States Cancer Statistics (USCS) database is not well known. In a multicenter retrospective study, Satpathy and colleagues evaluated whether Hispanic and American Indian or Alaska Native individuals have lower representation in the NCDB compared with the USCS database. They assessed individuals in both databases diagnosed with breast, colorectal, lung, and prostate cancer in two periods: 2004 to 2006 and 2017 to 2019. The team included data from 5,175,007 individuals. Of these, 0.5% were Amer...
