Estimation of Cancer Deaths Averted From Prevention, Screening, and Treatment Efforts, 1975-2020.

Importance: Cancer mortality has decreased over time, but the contributions of different interventions across the cancer control continuum to averting cancer deaths have not been systematically evaluated across major cancer sites.

Objective: To quantify the contributions of prevention, screening (to remove precursors [interception] or early detection), and treatment to cumulative number of cancer deaths averted from 1975 to 2020 for breast, cervical, colorectal, lung, and prostate cancers.

Design, Setting, And Participants: In this model-based study using population-level cancer mortality data, outputs from published models developed by the Cancer Intervention and Surveillance Modeling Network were extended to quantify cancer deaths averted through 2020.

The Association of Where Patients with Prostate Cancer Live and Receive Care on Racial Treatment Inequities.

Black individuals are less likely to be treated for prostate cancer even though they are more than twice as likely to die compared to White individuals. The complex causes of these inequities are influenced by social and structural factors, including racism, which contribute to the differential delivery of care. This study investigates how factors related to the location of where individuals live and receive care affect treatment inequities for prostate cancer between Black and White individuals.

Projected Outcomes of Reduced-Biopsy Management of Grade Group 1 Prostate Cancer: Implications for Relabeling.

Background: Implications of relabeling grade group (GG) 1 prostate cancer as non-cancer will depend on the recommended active surveillance (AS) strategy. Whether relabeling should prompt de-intensifying, PSA-based active monitoring approaches is unclear. We investigated outcomes of biopsy-based AS strategies vs PSA-based active monitoring for GG1 diagnoses under different patient adherence rates.

Trends in age and prostate-specific antigen at prostate cancer diagnosis between 2010 and 2019.

Recent studies have shown that de novo metastatic prostate cancer incidence in the United States increased from 2010 to 2019. Plausible explanations include delayed detection after recommendations against prostate cancer screening or upstaging associated with use of more sensitive imaging technologies. Using Surveillance, Epidemiology, and End Results patient cases and controlling for aging of the population, we found the median age and prostate-specific antigen (PSA) level at prostate cancer diagnosis increased by 1.
