Racial disparities in the use of SBRT for treating XXXX .

@entity1 @entity5
OBJECTIVES: Prior studies have shown that the surgical resection rate for black @entity1 with @entity5 is significantly lower than that of white @entity1 , which may partially explain the worse outcomes observed in this group. Over the past decade, however, there has been increasing utilization of stereotactic body radiotherapy (SBRT) as an alternative to surgical resection for inoperable @entity1 . We undertook a population-based study to evaluate potential racial disparities in the use of SBRT. MATERIALS AND METHODS: Using the National @entity5 Database, black and white @entity1 with Stage I NSCLC between 2003 and 2011 were identified. @entity1 were categorized based on primary treatment modality. Univariable and multivariable analyses were performed to identify demographic predictors of SBRT utilization in the non-operative population. RESULTS: A total of 113,312 @entity1 met the inclusion criteria. When compared to white @entity1 , black @entity1 were less likely to receive surgical intervention (66% vs. 58%, P<0.001) or SBRT (6.1% vs. 5.5%, P<0.001), and more likely to receive standard fractionated external beam radiation (EBRT) or no treatment. When confined to the non-operative cohort, multivariable logistic regression confirmed black race to be negatively associated with SBRT use compared to less aggressive therapy. CONCLUSION: In this national dataset, we confirmed prior observations that black @entity1 are less likely to receive surgery than white @entity1 , and also found that black @entity1 are less likely to receive SBRT. This suggests that even with emerging utilization of SBRT for inoperable candidates, black @entity1 continue to receive less aggressive therapy.
