Guideline-recommended treatment intensification was low for all patients with metastatic castration-sensitive prostate cancer, with less TI in Black patients in both Medicare and the VHA. Black race was associated with worse OS in Medicare but not the VHA. Medicaid patients had less TI and worse OS than those without Medicaid, suggesting poverty and race are associated with care and outcomes.

Genetic testing is a powerful tool used to identify a person’s risk for developing certain cancers that run in families. Identifying patients with a genetic alteration that increases susceptibility or predisposition to a certain disease is crucial to customize cancer treatment and guide primary and secondary prevention. However, there are low referral and genetic testing rates among racial minorities, especially among Blacks.

“While socioeconomic factors are associated with adverse cancer outcomes and contribute to racial disparities, our research suggests that triple negative breast cancer (TNBC) tumors appear to respond differently to chemotherapy in women of different races and ethnicities and this may also contribute to the disparities,” said senior author Maggie DiNome, M.D., chief of the Section of Breast Surgery in the Department of Surgery at Duke University School of Medicine and member of the Duke Cancer institute.

While the racial disparity gap is closing in some forms of cancer, future research should focus on identifying factors causing disparate outcomes to help reduce cancer-related disparities.

There are over 434,000 clinical trials registered with Clinicaltrials.gov. However, data from the FDA indicate that 75% of trial participants in 2020 identified as white, while only 11% identified as Hispanic, 8% identified as Black or African American, and 6% identified as Asian
