About The Study: This quality improvement analysis of clinical trials for metastatic breast, lung, colon, pancreatic, and prostate cancers found that a large proportion of the U.S. population lived within 30 miles of a clinical trial site. This finding suggests that while many clinical trials are available, they are not evenly distributed across the country and may not be accessible to all individuals, particularly racial and ethnic minority individuals. This disparity in access to clinical trials raises important questions about equity and fairness in the distribution of health care resources and opportunities for treatment.
