RESUMO
PURPOSE: Disparities in access to surgical care are associated with poorer outcomes in patients with cancer. We sought to determine whether vulnerable populations undergo an expected rate of surgery for Stage I-IIIA lung cancer in North Carolina (NC). METHODS: We calculated the proportional surgical ratio (PSR) to identify a potential disparity in surgery rates for early stage (I-IIIA) lung cancer, first in the five counties with the worst health outcomes (LRC) and subsequently the entire state. The reference was the five healthiest counties (HRC), initially, and then the single county with the best health outcomes. RESULTS: In 2016, 3,452 individuals with Stage I-IIIA lung cancer were diagnosed in NC of which 246,854 resided in LRC, whereas 1,865,588 resided in HRC. A total of 453 operable lung cancers were diagnosed in the HRC and 107 in the LRC. The observed lobectomy rate in HRC was 40.1% (range 20.2-58.3%) of early-stage lung cancer and 19% (range 12-36%) for LRC. The PSR was 0.65 (95% confidence interval [CI] = 0.35, 0.90). For all 99 counties across NC, the PSR ranged from 0.33 to 0.96 (mean = 0.49, standard deviation [SD] = 0.10). In a multivariable model, only other primary care provider ratio (relative rate per 100 increase = 0.997; 95% CI = 0.994, 0.999) was significantly associated with PSR. CONCLUSIONS: Individuals residing in LRC in NC are 42% less likely to undergo surgery for operable lung cancer than patients living in HRC. Understanding how factors impact access is key to designing informed interventions.

BACKGROUND: Recent evidence suggests an increased incidence of venous thromboembolism among cancer patients of Black race. This study aimed to determine whether Black patients undergoing major oncologic resection experience increased rates of postoperative venous thromboembolism. METHODS: A cohort study of patients who underwent major oncologic resection was performed using American College of Surgeons National Surgical Quality Improvement Program (2016-2018). Primary outcome was venous thromboembolism within 30 days of surgery. Multivariable logistic regression was performed to evaluate the independent association of race and venous thromboembolism. RESULTS: Of 91,707 patients, 67.7% were White, 9.5% Black, and 22.9% other race. Venous thromboembolism rates differed slightly by race: 2.2% among Whites, 2.4% Blacks, and 1.8% other (P = .002). Black patients were older, with higher rates of obesity, diabetes, and smoking. By multivariable logistic regression, risk of venous thromboembolism was lower among patients of other compared with White race (odds ratio 0.83; 95% confidence interval, 0.74-0.94). There was no difference in odds of venous thromboembolism among Black relative to White patients (odds ratio 1.08; 95% confidence interval, 0.93-1.26). When stratified by age, rates of venous thromboembolism were >50% higher among Black patients older than 75 years compared with White patients (odds ratio 1.54; 95% confidence interval, 1.17-2.03). CONCLUSION: Despite evidence that Black patients with cancer experience higher rates of venous thromboembolism, they do not appear to have an increased risk in the postoperative period.
