      Highlights

      • Timely surgery is linked to outcome in endometrial cancer patients.
      • Disparities in the receipt of timely surgery are noted among marginalized patients in Ontario's public healthcare system.
      • Other surgical quality indicators are not associated with social determinants of health in Ontario.
      • Reducing surgical wait times among marginalized cancer patients is an important deliverable in public healthcare.

      Abstract

      Objective

      Timely surgery has been shown to impact outcome in endometrial cancer patients. Social determinants of health (SDH) are associated with adverse cancer outcomes. We sought to evaluate the association of SDH with surgical treatment indicators in endometrial cancer patients in a public healthcare system.

      Methods

      Endometrial cancer patients in Ontario, Canada, diagnosed between 2009 and 2017 were identified, and clinical, social and demographic variables were extracted from administrative databases. Validated community marginalization scores that include material deprivation, residential instability and ethnic concentration were used for stratification. Surgical treatment features were compared across marginalization quintiles using chi-square, Fischer exact or Wilcoxon rank sum tests as appropriate. Predictors of timely surgical treatment were evaluated with logistic regression.

      Results

      20228 patients were identified of whom 14,423 had primary hysterectomy for a preoperative diagnosis of endometrial cancer. Fewer patients in marginalized communities received surgery (89% vs. 93%, p < 0.001). Surgical delay was longer among marginalized patients and 78% had surgery within 12 weeks compared to 84% of those least marginalized (p < 0.0001). Other quality indicators of surgical treatment were not negatively associated with marginalization. On multivariable analysis adjusted for patient and disease factors, marginalization was independently associated with increased odds of delayed surgery (OR = 0.94/quintile, CI 0.91–0.97, p < 0.001).

      Conclusions

      Social marginalization is associated with decreased likelihood of having surgery and with delayed surgery among endometrial cancer patients in Ontario. This may be mediated by delayed presentation and real or perceived barriers to access. Reducing surgical wait times among marginalized cancer patients is an important deliverable in public healthcare.
