Response to radiotherapy for prostate cancer better in Black men
Ting Martin Ma, MD, PhD, from the University of California, Los Angeles and colleagues conducted a systematic literature review and meta-analysis of data from randomized clinical trials of definitive radiotherapy for patients with localized prostate cancer. The selected studies enrolled a substantial number of Black men and reported on treatment-specific and overall outcomes.
Based on seven clinical trials (8814 patients; 18.5% Black), the researchers found that at enrollment, Black men were more likely to have high-risk disease features. However, Black men were less likely to experience biochemical recurrence, distant metastasis, or prostate cancer-specific mortality. There were no significant differences noted in all-cause mortality.
“The findings of this meta-analysis noted that Black men enrolled in randomized clinical trials presented with more aggressive disease features but had better treatment with disease-specific outcomes with radiotherapy-based therapy compared with White men. This suggests other important factors are associated with outcome, such as access to care as sources of disparity,” the researchers summarized.
