Does cancer clinical trial enrollment for sexual and gender minority people differ from heterosexual, cisgender people?

Background

Sexual and gender minority (SGM) people experience cancer disparities compared to heterosexual and cisgender (non-SGM) people and likely have barriers to cancer clinical trial enrollment. Data are sparse, however, regarding cancer clinical trial enrollment for SGM versus non-SGM people.

Methods

Using data from the 2020 Behavioral Risk Factor Surveillance Survey (BRFSS), we applied a logistic regression to assess associations between SGM status and clinical trial enrollment for 346 SGM and 9441 non-SGM people diagnosed with cancer. The model was adjusted for age at diagnosis, race/ethnicity, partnership status, education, employment, and sex assigned at birth.

Results

SGM individuals had 94 % greater odds than non-SGM individuals to report participation in a clinical trial (aOR 1.94; 95 % CI 1.02–3.68) after adjusting for other factors.

Conclusions

Data from the BRFSS suggest that SGM people with cancer have higher odds of clinical trial enrollment compared to non-SGM people with cancer. Future work is needed to prospectively track oncology treatment, including clinical trial participation, and outcomes of SGM people versus non-SGM people with cancer. Other studies will be needed to develop and implement systematic, consistent, and non-stigmatizing sexual orientation and gender identity data collection methods.
