Abstract

Purpose: To identify factors associated with receipt of partial nephrectomy (PN) and minimally invasive surgery (MIS) in patients with clinical T1 renal cell carcinoma (RCC) using the National Cancer Data Base (NCDB). Methods: We queried the NCDB from 2010 to 2014 identifying patients treated surgically for cT1a-bN0M0 RCC. Logistic regression was used to examine associations between socioeconomic, clinical, and treatment factors, and receipt of MIS or PN within the T1 patient population. Results: Our cohort included 69,694 patients (cT1a, n = 44,043; cT1b, n = 25,651). For cT1a tumors, 70% of patients received PN and 65% underwent MIS. For cT1b tumors, 32% of patients received PN and 62% underwent MIS. cT1a and cT1b patients with household income < $62,000, without private insurance, and treated outside academic centers were less likely to receive MIS or PN. cT1a patients traveling > 31 miles were more likely to undergo MIS. For both cT1a/b, the farther a patient traveled for treatment, the more likely a PN was performed. Conclusion: Data showed an increase in utilization of MIS and PN from 2010 to 2014. However, patients in the lowest socioeconomic groups were less likely to travel and were more likely to receive more invasive treatments. On the basis of these findings, additional research is needed into how regionalization of RCC surgery affects treatment disparities.
