To evaluate trends in the utilization of stereotactic radiosurgery (SRS) versus whole brain radiation therapy (WBRT) for brain metastases and assess changes in disparities related to race, income, and insurance coverage over time.
Key Findings:
SRS has become increasingly preferred over WBRT due to comparable survival outcomes and reduced neurotoxicity, with a noted increase in SRS utilization from X% to Y% over the study period.
Disparities in SRS utilization exist, particularly affecting marginalized populations, with Z% of low-income patients receiving SRS compared to A% of higher-income patients.
Patients from lower-income backgrounds and those without private insurance are less likely to receive SRS, highlighting a significant gap in access.
Interpretation:
The study highlights significant disparities in access to SRS for brain metastases, indicating a need for targeted interventions to improve treatment equity and patient outcomes.
Limitations:
The study is retrospective and may not capture all relevant clinical factors, introducing potential biases.
Data disaggregation was limited, potentially overlooking nuances within racial and ethnic groups.
Conclusion:
SRS utilization patterns have evolved, but disparities remain, necessitating further research into specific barriers and policy changes to enhance access to advanced cancer treatments.
