N2 - Objective We sought to investigate the impact of race, socioeconomic status (SES), and health care system characteristics on receipt of specific components of National Comprehensive Cancer Network guideline care for stage IIIC/IV ovarian cancer. Study Design Patients diagnosed with stage IIIC/IV epithelial ovarian cancer between Jan. 1, 1996, through Dec. 31, 2006, were identified from the California Cancer Registry. Multivariate logistic regression analyses evaluated differences in surgery, chemotherapy, and treatment sequence according to race, increasing SES (SES-1 to SES-5), and provider annual case volume. Results A total of 11,865 patients were identified. Median age at diagnosis was 65.0 years. The overall median cancer-specific survival was 28.2 months. African American race (odds ratio [OR], 2.04; 95% confidence interval [CI], 1.45-2.87) and care by a low-volume physician (OR, 19.72; 95% CI, 11.87-32.77) predicted an increased risk of not undergoing surgery. Patients with SES-1 (OR, 0.71; 95% CI, 0.60-0.85) and those treated at low-volume hospitals (OR, 0.88; 95% CI, 0.77-0.99) or by low-volume physicians (OR, 0.80; 95% CI, 0.70-0.92) were less likely to undergo debulking surgery. African American race (OR, 1.55; 95% CI, 1.24-1.93) and SES-1 (OR, 1.80; 95% CI, 1.35-2.39) were both significant predictors of not receiving chemotherapy. African American patients were also more likely than whites to receive no treatment (OR, 2.08; 95% CI, 1.45-2.99) or only chemotherapy (OR, 1.55; 95% CI, 1.10-2.18). Patients with low SES were more likely to receive no treatment (OR, 1.95; 95% CI, 1.44-2.64) or surgery without chemotherapy (OR, 1.67; 95% CI, 1.38-2.03). Conclusion Among patients with advanced-stage ovarian cancer, African American race, low SES, and treatment by low-volume providers are significant and independent predictors of receiving no surgery, no debulking surgery, no chemotherapy, and nonstandard treatment sequences.
