Racial Disparities in Histology and Short-Term Renal Functional Outcomes Following Robotic Nephron-Sparing Surgery
2017
Abstract Purpose To identify variations in renal function and histology between Caucasian Americans (CA) and African Americans (AA) undergoing robotic nephron-sparing surgery (NSS). Methods A retrospective chart review was performed on patients who underwent NSS. Multivariate analysis identified factors affecting postoperative estimated glomerular filtration rate (eGFR). Histology was re-reviewed by pathology to confirm papillary type. Results A total of 331 patients underwent NSS: CA (n = 212), AA (n = 105), Hispanic (n = 10), and other (n = 4). AA average age (60.1 years) was lower than CA (62.3 years) ( P P = .021). AA had a higher incidence of diabetes (58.2%) and hypertension (93.9%). Preoperative average eGFR was similar: 70.35 mL/min for AA versus 69.06 mL/min for CA. Average postoperative eGFR was 50.59 mL/min for AA and 57.85 mL/min for CA. Postoperative creatinine increased more in AA (0.44 mg/dL) versus CA (0.33 mg/dL) ( P Conclusions AA patients were treated at a younger age, with a larger proportion of women. Postoperatively, AA experienced a greater increase in serum creatinine. Final histology demonstrated greater papillary RCC incidence in AA and increased likelihood for type 2 papillary RCC, a more aggressive histology.
