Breast, Colorectal, Lung, Prostate, and Cervical Cancer Screening Prevalence in a Large Commercial and Medicare Advantage Plan, 2008-2020.

This study aimed to comprehensively assess breast, colorectal, cervical, lung, and prostate cancer screening rates and trends in the United States over time among individuals for whom screening is recommended by the United States Preventive Services Task Force (USPSTF). This retrospective study was conducted in two-year intervals from January 1, 2008 to February 29, 2020, using Optum's de-identified Clinformatics® Data Mart Database, which includes Medicare Advantage and commercially insured members. Screening-eligible individuals, who had not previously had the cancer being screened and met USPSTF criteria for screening, were identified at various time points within the study timeframe for relevant screening tests within five cancer types: breast, colorectal, cervical, lung, and prostate. In the 2020 analysis period, patients who were eligible for cancer screening included: breast: 1,620,588; colorectal: 2,763,736; cervical: 1,371,506; lung: 1,491,594; prostate: 1,126,249. Breast and cervical cancer screening prevalence rates were highest (64.4% and 63.8%, respectively), followed by colorectal (29.5%), prostate (11.7%), and lung (3.8%). Black/African American individuals and Hispanics had moderately low screening rates for cervical (58.6%) and breast (61.8%) cancer, respectively; Hispanics had the lowest screening rates for prostate cancer (6.1%). Those residing in the West had lower screening rates for breast (58.9%), cervical (62.1%), and prostate (5.6%) cancer. Screening rates remained stable over time for breast, colorectal, and lung cancer, and changed significantly for cervical (-9.5%, 2012-2020) and prostate (+7.3%, 2008-2020) cancer. Real-world cancer screening rates remain suboptimal and low, and efforts to increase screening uptake and reduce cancer health disparities remain critical.
