Objective: To investigate disparities in the frequency of ovarian cancer-related surgical procedures and access to high-volume surgical providers among women undergoing initial surgery for ovarian cancer according to race.
Methods: The California Office of Statewide Health Planning and Development database was accessed for women undergoing a surgical procedure that included oophorectomy for a malignant ovarian neoplasm between 1/1/06 and 12/31/10. Multivariate logistic regression analyses were used to evaluate differences in the odds of selected surgical procedures and access to high-volume centers (hospitals ≥ 20 cases/year) according to racial classification.
Results: A total of 7933 patients were identified: White = 5095 (64.2%), Black = 290 (3.7%), Hispanic/Latino = 1400 (17.7%), Asian/Pacific Islander = 836 (10.5%) and other = 312 (3.9%). White patients served as reference for all comparisons. All minority groups were significantly younger (Black mean age 57.7 years, Hispanic 53.2 years, Asian 54.5 years vs. 61.1 years, p < 0.01). Hispanic patients had lower odds of obtaining care at a high-volume center (adjusted OR (adj. OR) = 0.72, 95% CI = 0.64-0.82, p < 0.01) and a lower likelihood of lymphadenectomy (adj. OR = 0.80, 95% CI=0.70-0.91, p<0.01), bowel resection (adj. OR = 0.80, 95% CI = 0.71-0.91, p < 0.01), and peritoneal biopsy/omentectomy (adj. OR = 0.69, 95% CI = 0.58-0.82, p<0.01). Black racial classification was associated with a lower likelihood of lymphadenectomy (adj. OR = 0.76, 95% CI = 0.59-0.97, p = 0.03).
Conclusions: Among women undergoing initial surgery for ovarian cancer, Hispanic patients are significantly less likely to be operated on at a high-volume center, and both Black and Hispanic patients are significantly less likely to undergo important ovarian cancer-specific surgical procedures compared to White patients.
