OBJECTIVE: Determine if racial/ethnic disparities exist for access to high-volume surgeons (HVS) for patients with ovarian cancer. METHODS: Retrospective study of ovarian cancer surgeries identified by the California Cancer Registry (CCR) linked to hospital discharge data (1991-2002). Surgeon volume was defined as HVS (>10 ovarian cancer surgeries/year), middle volume (MVS; 2-9/year), and low volume (LVS; </=1/year). Multivariate ordered logistic regression predicting surgeon volume provided estimates of relative risk (RR) of surgeon volume by patient race/ethnicity. RESULTS: 13,186 women had ovarian cancer (mean age 57.8 years; 72% non-Hispanic White (NHW), 4% Black, 8% Hispanic). 25% of cases were treated by HVS, 31% by MVS, and 44% by LVS. Compared to NHW, Black (RR: 0.70, p<0.05) and Hispanic women (RR: 0.75, p<0.05) were less likely to have care by a HVS. Hispanic women were significant more likely to have surgery by LVS (RR: 1.1; p<0.05). CONCLUSIONS: Disparities in access to HVS for cancer care exist for minority women. Selective referral to high-volume providers should be considered to improve outcomes among minority women.
