ABSTRACT
BACKGROUND:
Socioeconomic status (SES) disparities in the surgical management of patients with non-small cell lung cancer (NSCLC) are well described. Disparities in the receipt of adjuvant chemotherapy are poorly understood. We assessed the influence of SES on adjuvant chemotherapy after resection in patients with pN1 NSCLC.METHODS:
The National Cancer Database was queried for cN0/N1 NSCLC patients who underwent surgical resection and had demonstrated pN1 disease. This cohort was further divided into those who received multiagent adjuvant chemotherapy (MAAC) vs surgery-only treatment. Factors associated with treatment assignment were examined, and long-term survival was compared.RESULTS:
Of the 14,892 patients who underwent resection for pN1 disease, 8061 (54.1%) received MAAC. Patients were less likely to receive MAAC if they resided in rural areas (odds ratio, 1.23; 95% confidence interval [CI], 1.11-1.37; P < .001), or were uninsured or on Medicaid (odds ratio, 1.23; 95% CI, 1.07-1.41; P = .004). The propensity score-weighted 5-year survival was significantly higher for those receiving MAAC compared with surgery only (53.6% vs 39.5%, log-rank P < .001). Lower income (hazard ratio, 1.06; 95% CI, 1.00-1.12; P = .044) and uninsured or Medicaid insurance status (hazard ratio, 1.22; 95% CI, 1.13-1.31; P < .001) were independently associated with increased mortality by Cox regression in the propensity score-weighted cohort.CONCLUSIONS:
pN1 NSCLC patients living in rural areas or who are uninsured or on Medicaid insurance are at increased risk of not receiving MAAC. Treatment with MAAC significantly improves long-term survival of pN1 patients. Efforts should be made to ensure these at-risk groups receive guideline-concordant care.
