Sociodemographic predictors of surgery refusal in patients with stage I‐III colon cancer

摘要

Abstract Background and Objectives Over 104?000 cases of colon cancer are estimated to be diagnosed in 2020. Surgical resection is a critical part of colon cancer treatment and adequate resection impacts prognosis. However, some patients refuse potentially curative surgery. We aimed to identify the rate and predictors of surgery refusal among patients with colon cancer. Methods The National Cancer Database (2004‐2015) was queried for patients diagnosed with stage I‐III colonic adenocarcinoma. Sociodemographic factors, clinical features, and treatment facility characteristics were collected. Patients who underwent surgery with curative intent were compared to those who refused surgery. Multivariable analysis was used to identify factors associated with surgery refusal. Adjusted survival analysis was performed on propensity‐matched cohorts. Results A total of 151?020 patients were included and 1071 (0.71%) refused surgery. In multivariable analysis older age, Black race, higher Charlson comorbidity score, Medicaid, Medicare, or lack of insurance were predictive of refusing surgery. After propensity matching, there was a significant difference in 5‐year survival for patients who refused surgery vs those who underwent surgery ( P ??.001). Conclusions There are racial and socioeconomic disparities in the refusal of surgery for colon cancer. Further studies are needed to better understand the drivers behind differences in refusing curative surgery for colon cancer.
