Background: Lung cancer is the leading cause of cancer death in the United States. Receipt of curative-intent surgery for early-stage non–small cell lung cancer (NSCLC) is associated with disparities in race and socioeconomic status, which is subsequently related to the outcome of NSCLC. This study aimed to examine the racial disparity in receipt of curative-intent surgery among early-stage NSCLC in Florida. Methods: A total of 80,458 patients with early-stage NSCLC diagnosed from 2005 to 2017 were identified from the statewide cancer registry, Florida Cancer Data System (FCDS). Percentage of patients receiving curative-intent surgery was calculated for each race/ethnicity. FCDS data was linked to discharge data containing comorbidity information for each lung cancer patient. There was a 94% match between FCDS and discharge data. Multivariable logistic regression was used to determine the impact of race on receipt of curative-intent surgery for early-stage NSCLC. Results: Among 80,458 patients with early-stage NSCLC, 66,761 (83.0%) were White, 5,503 (6.8%) were Black and 6,981 (8.7%) were Hispanic. Of note, 69.5% Hispanic patients lived in South Florida. Asian patients (59.9%) had the highest proportion of curative surgery, followed by Hispanics (57.8%), Whites (52.9%) and Blacks (42.6%). In the multivariable model, patients with Charlson Comorbidity Index (CCI)≥3 had 34% lower odds of having curative surgery (OR, 0.66; 95% CI, 0.62 to 0.7) compared to patients who did not have any comorbidity (CCI=0). Highest poverty levels had 27% lower odds of receiving curative-intent surgery compared to lowest (OR: 0.73; 95% CI: 0.68 to 0.78). After adjusting for sociodemographic factors (i.e., age, sex, race, insurance, region) and clinical factors (i.e., histology, AJCC stage, CCI, smoking status), Blacks had 27% lower odds of receiving curative-intent surgery (OR, 0.73; 95% CI, 0.68 to 0.79), whereas Hispanics had 22% (OR, 1.22; 95% CI, 1.14 to 1.30) and Asians had 19% (OR, 1.19; 95% CI, 0.98 to 1.46) higher odds than Whites. In the stratified analysis by regions, Blacks had lower odds of receiving curative-intent surgery than Whites in all regions across Florida while Hispanics had higher odds of receiving surgery than Whites only in South Florida (OR, 1.29; 95% CI, 1.18 to 1.41). Conclusions: There are persistent racial disparities in receipt of curative-intent surgery for early-stage NSCLC in Florida. Specifically, Blacks are receiving less curative-intent surgery, despite adjustments for comorbidities, socio-economic status, and insurance. Ethno-regional differences within different regions of Florida are evident with Hispanics surpassing all other races in receipt of curative treatment in heavily Hispanic South Florida.
