- W2791169102 abstract "641 Background: Weighing operative, oncologic and comorbid risks guide treatment recommendations for localized kidney cancers. We hypothesize that individualized surgical decision making may also be influenced by surgical center and volume. Methods: The National Cancer Database (NCDB) was queried for patients 18-80 years old with pT1a-T2bN0M0 RCC, treated by partial (PN) or radical nephrectomy (RN), or ablation (ABL) from 2004-2014. After adjusting for clinicopathologic characteristics, we evaluated the association of hospital volume (vol) and center classification with receipt of PN. High vol was defined as the top 10% in treatment volume. Results: 142,090 patients met inclusion criteria, where 58% (n = 82,498) and 41% (n = 58,873) were treated by RN and PN, respectively, and 1% (n = 719) by ABL. The utilization of PN increased over time (2004: 24% vs 2014: 53%; p < 0.001). Stratified by tumor stage, 60% (n = 47,484) of pT1a and 24% (n = 9,906) of pT1b tumors were treated by PN. On multivariate analysis, patients treated at a high-vol center (OR 1.89, 95% CI 1.57-2.28) had a greater likelihood of receiving a PN when compared to treatment elsewhere. Additionally, compared to a community cancer program, treatment at a comprehensive community cancer center (OR 1.39, 95%CI 1.23-1.57), academic/research (OR 1.67, 95%CI 1.47-1.90), or integrated network cancer program (OR 1.48, 95%CI 1.24-1.77) had a higher likelihood of receiving a PN. The median distance travelled was 9.8 and 18.1 miles, for treatment at non high vol and high vol centers, respectively. An inverse correlation was noted between increasing tumor stage and receipt of PN, compared to pT1a tumors (pT1b [OR 0.22, 95%CI 0.20-0.23], pT2a [OR 0.06, 95%CI 0.05-0.06], pT2b [OR 0.03, 95%CI 0.02-0.03]). Conclusions: In the NCDB, despite increased utilization of PN at higher vol centers, the majority of localized renal tumors are still treated with RN. Smaller tumor size, treatment at a higher vol centers, comprehensive community cancer centers, academic/research programs, or integrated network cancer programs increase the likelihood of receipt of PN. Evaluation of population based trends aid in understanding localized RCC surgical management and may help quality improvement efforts." @default.
