Purpose: Social determinants may influence health-related quality of life (HRQOL) among women with ovarian cancer, potentially creating disparities in clinical outcomes. We investigated the relationship between HRQOL and social determinants of health, including travel distance to access cancer care and health insurance type, among women participating in a randomized trial of primary adjuvant treatment for advanced ovarian cancer. Methods: The Functional Assessment of Cancer Therapy-Ovarian (FACT-O) questionnaire captured HRQOL (physical well-being, functional well-being, ovarian-specific, and trial outcome index [TOI]) prior to chemotherapy (baseline), during the trial, and 84 weeks after initiation of chemotherapy for women with advanced epithelial ovarian, primary peritoneal, or fallopian tube cancer. We constructed bivariate and multivariable linear mixed effects models examining the associations of social determinants of health (individual-level and contextual factors) with HRQOL scores at 84 weeks, clustering participants (n = 993) within treatment centers, and Census regions and controlling for baseline HRQOL. Results: Most individual-level (race, age, cancer stage, adverse events) and contextual (travel distance to treatment center, community socioeconomic status) factors were not statistically significantly associated with HRQOL. Compared to participants with private health insurance, other participants had lower mean HRQOL (physical well-being: public insurance, − 1.00 (standard error[SE] = 0.49) points, uninsured, − 1.93 (SE = 0.63) points; functional well-being: public, − 1.29 (SE = 0.59), uninsured, − 1.98 (SE = 0.76); ovarian cancer-specific: public, − 1.60 (SE = 0.59), uninsured, − 1.66 (SE = 0.75); TOI: public, − 3.81 (SE = 1.46), uninsured, − 5.51 (SE = 1.86); all p <.05). Conclusions: Private health insurance was associated with improved HRQOL at the completion of treatment for advanced stage ovarian cancer. Implications of health insurance on HRQOL should be further investigated, particularly among women with ovarian cancer who receive standard of care treatment.
