I commend the authors for their comprehensive investigation into racial and ethnic disparities in the utilization of partial nephrectomy and robotic surgery for renal cell carcinoma.1 The authors analyzed data from the National Cancer Database spanning 2010 to 2019. A total of 122,920 patients with clinical cT1a to cT2 renal cell carcinoma who underwent surgical treatment were identified. After adjusting for potential confounding factors, the analysis demonstrated that non-Hispanic Black and Hispanic patients were significantly less likely to receive partial nephrectomy and robotic-assisted surgery for cT1a tumors compared with non-Hispanic White patients. These disparities extended beyond cT1a lesions. Hispanic patients remained less likely to receive nephron-sparing surgery for cT1b to cT2 tumors, while non-Hispanic Black patients consistently had lower odds of undergoing robotic-assisted surgery at all evaluated stages. During the study period, the gap in partial nephrectomy utilization narrowed among non-Hispanic White, Hispanic, and non-Hispanic Black groups for cT1a tumors. Notably, non-Hispanic Black patients had higher odds of receiving partial nephrectomy for T1b and T2 tumors. The underlying causes of these disparities are multifactorial. Compared with patients with private insurance, those with Medicare, Medicaid, or no insurance were less likely to receive robotic surgery.2 Lower socioeconomic status was also associated with reduced utilization of robotic surgery.2 Non-Hispanic Black and Hispanic patients were more likely to receive non–guideline-based treatment.3 Non-Hispanic Black patients were more likely to receive treatment at low-volume centers, which may have limited access to advanced technology and specialized expertise.3 Non-Hispanic Black patients had higher rates of refusing recommended treatment, a trend often linked to historical medical mistrust and communication barriers.4 Potential strategies to address these disparities include expanding insurance coverage, improving access to care, standardizing referral pathways to ensure equitable access, and providing provider education on implicit bias and guideline-based care.
