Demographic and Socioeconomic Disparities Among Cancer Survivors in Clinical Trials Participation, USA, 2016–2018

The established findings of lower representation of minority population in clinical trials are skewed by the national representation of the US population by race where they account only for 30%, making it difficult to compare the participation rate by race. We report the direct age-adjusted demographic and socioeconomic disparities in clinical trial participation among cancer survivors using the most recent national survey data. In 2018, 7.1% of cancer survivors reported participating in the clinical trial as a part of their cancer treatment. The participation rate was significantly higher among younger adults (age 18–24, 19.1%), male (8.5%), black (19.8%), and Hispanic (14.4%) cancer survivors, while rate was lower among female (4.2%), and white (5.4%). By marital status, 8.5% of unmarried and 3.5% of married cancer survivors reported clinical trial participation. These results help explain the demographic disparities in cancer survivors and drawing attention to targeted education and awareness intervention for ideal cancer care.
