Abstract

Abstract: Objective: Treatment of renal cell carcinoma has evolved with emphasis on nephron preservation for small renal masses. Our objective was to evaluate the proportions of treatment types for octogenarians with clinical stage 1 renal cell carcinoma. Materials and Methods: The National Cancer Database was analyzed from 2004 to 2015. Patients with clinical stage 1, tumor size ≤ 7 cm, and age 80–89 years old were compared to a younger control arm of patients ≤ 70 years old. Treatment modality was categorized as radical nephrectomy (RN), partial nephrectomy (PN), percutaneous ablative therapy (PAT), and no treatment (NT). Primary outcome was treatment utilization over time using estimated annual percentage change (EAPC). Secondary outcomes included logistic regression for 30 day readmission after treatment and any definitive tumor treatment choice. Results: 18, 903 octogenarians were identified and compared to a control of 142, 179 patients ≤ 70 years old. Overall, NT (36%) was the most common modality for octogenarians while PN (44.8%) was most common for the control arm. Using EAPC for octogenarians, we found increases for PAT (7.1%), PN (2.8%), and NT (1.6%) but a decrease for RN (−4.6%). EAPC for the younger cohort noted increases for PAT (6.8%), PN (5.4%), and NT (4.4%) but a decrease for RN (−5.5%). Conclusion: For octogenarians with stage 1 renal cell carcinoma, minimally invasive treatments are increasingly utilized, while RN is decreasing. Compared to a younger cohort, a greater proportion of octogenarians are receiving NT. These findings remain encouraging for appropriate treatment of localized disease in patients with advanced age.
