Racial Disparities in Cancer Presentation and Outcomes: The Contribution of Overdiagnosis.

ABSTRACT:

Background

Racial disparities in cancer have been attributed to population differences in access to care. Differences in cancer overdiagnosis rates are another, less commonly considered cause of disparities. Here, we examine the contribution of overdiagnosis to observed racial disparities in papillary thyroid cancer and estrogen/progesterone receptor positive (ER/PR+) breast cancer.

Methods

We used Surveillance, Epidemiology, End-Results (SEER) 13 for analysis of white and black non-Hispanic persons with papillary thyroid cancer or ER/PR+ breast cancer (1992-2014). Analyses were performed using SeerStat (v8.3.5, March 2018). All statistical tests were two-sided.

Results

White persons had higher incidence of papillary thyroid cancer than black persons (14.3 vs 7.7 case
