Abstract

Introduction: In stage IV non–small-cell lung cancer (NSCLC), survival has significantly improved. Despite such trends, it has been noted that patients frequently refuse treatment. Therefore, we explored the factors associated with treatment refusal in NSCLC. Patients and Methods: Utilizing the National Cancer Data Base (NCDB), we identified all stage IV NSCLC cases from 2004 to 2014. Patients who received cancer treatment outside of the reporting facility were excluded. Multivariable logistic regression models were used to determine associations with treatment refusal. Results: A total of 341,993 patients were identified; 5.4% of patients refused radiotherapy and 10.3% refused chemotherapy despite provider recommendations. The proportion of patients refusing radiotherapy and chemotherapy increased over time from 4.2% to 7.3% and 7.9% to 15%, respectively (P < .001). In multivariable analysis, men were less likely to refuse treatment compared to women (respectively, odds ratio = 0.80; 95% confidence interval, 0.76–0.84; P < .001; odds ratio = 0.82; 95% confidence interval, 0.80–0.85; P < .001, respectively). Factors associated with radiotherapy refusal included: Medicaid or Medicare as primary insurance, uninsured status, low household median income, and lower educational level. Regarding chemotherapy, uninsured patients, Medicaid patients, and patients with a high comorbidity index were more likely to refuse chemotherapy. Asians had lower rates of chemotherapy refusal relative to non-Hispanic whites. Non-Hispanic whites, Hispanics, and Asians had increasing chemotherapy refusal rates over time, while non-Hispanic blacks had less pronounced trends over time. Conclusion: Socioeconomic factors rather than race/ethnicity appear to influence the refusal of cancer treatment in patients with stage IV NSCLC. Assessing socioeconomic challenges should be an essential part of patient evaluation when discussing treatment options.
