Pdf Summary

This study aimed to examine trends and investigate racial disparities in the receipt of curative-intent treatment for early-stage non-small cell lung cancer (NSCLC). The researchers utilized population-based data from the Florida Cancer Data System (FCDS) to identify over 63,000 early-stage NSCLC cases diagnosed in Florida from 2005 to 2017. They excluded patients with small cell lung cancer and those who refused recommended surgery or radiation therapy. The data were linked to the Florida Agency for Health Care Administration (AHCA) to gather comorbidity and treatment information.<br /><br />The study found that only 28% of early-stage NSCLC patients received curative-intent treatment. Racial disparities were observed, with Black patients being less likely to receive any type of curative-intent treatment compared to White patients. Geographic differences were also noted, with South Florida having higher rates of curative-intent treatment. However, Hispanic patients in South Florida had better access to treatment compared to non-Hispanic Whites. The proportion of patients receiving curative-intent surgery remained stable from 2005 to 2014 but decreased afterward, while the proportion of patients receiving stereotactic body radiotherapy (SBRT) increased during the study period.<br /><br />The study highlights the underutilization of guideline-recommended curative-intent treatment for early-stage NSCLC and the persistence of racial disparities in treatment. The findings suggest complex healthcare delivery challenges and the need for interventions to address these disparities. The strengths of the study include its large population-based sample and the comprehensive assessment of comorbidities and treatment information. However, limitations include the dynamic nature of cancer staging criteria and the lack of information on lifestyle behaviors and social support.<br /><br />In conclusion, this study underscores the need to improve the rates of curative-intent treatment for early-stage NSCLC and address racial disparities in treatment outcomes. Future research should focus on identifying barriers to treatment access and developing strategies to overcome them.
