The missing data: A review of gender and sex disparities in research

Abstract

This article highlights the gender data gaps in clinical trial inclusion and funding, with a particular focus on gynecologic oncology. Female patients have historically been excluded from clinical trials across all medical domains. Despite recent improvements, female patients remain underrepresented in key diseases, including several cancer types, despite experiencing increased burden of disease. Lack of representation is particularly stark for patients in racial, ethnic, and gender minoritized populations, including in gynecologic cancer trials. Furthermore, female health conditions receive disproportionately small amounts of funding relative to their disease burden. Despite their high lethality, gynecologic cancers, including ovarian, cervical, and uterine malignancies, rank among the lowest funded cancer sites from the National Cancer Institute. Likewise, there is significant bias against female investigators with regard to funding, publication, and academic advancement, which affects the prioritization of women’s health. In combination, gender disparities at multiple steps along the research pathway from investigator and disease funding to trial inclusion to publication and dissemination of research perpetuate a significant data gap in the diagnosis, treatment, and prevention of diseases affecting female patients, including gynecologic cancers. Strategies to improve this gender gap and prioritize women’s health funding include increasing female representation in clinical trials with a specific focus on inclusion of patients from historically marginalized backgrounds, considering disease burden–based funding policies, and prioritizing female academic leadership opportunities.
