The effect of race and gender on the surgical management of the small renal mass

Abstract Background To date, no population studies have been designed to assess the impact of race and gender on the rate of nephron-sparing surgery (NSS) across the United States. Materials and methods The Surveillance, Epidemiology, and End Results (SEER) registry was queried for patients with T1a renal cell carcinoma (RCC) treated over the most recent decade, 1998–2007. Baseline socio-demographic data were compared between Caucasian and African-American patients using χ2 and t- test analysis, and rates of radical nephrectomy (RN) were compared for all permutations of race and gender. A multivariate logistic regression model was in turn created with these variables to predict the odds of undergoing a radical nephrectomy. No prior assumptions were made regarding superiority of partial nephrectomy (PN) over RN as a therapeutic intervention. Results A total of 14,953 patients were eligible for inclusion in this study, and of these, 1,804 (12%) were African-American. Comparably, African-American patients were younger (
