RESUMO
OBJECTIVES: To examine real-world characteristics, journey, and outcomes among patients with locoregional, nonmetastatic renal cell carcinoma (RCC). METHODS: A retrospective analysis of medical records from the ConcertAI Oncology Dataset was performed on adults in the United States with newly diagnosed nonmetastatic RCC between January 2012-December 2017 who received surgical treatment, and were followed until August 2021. Patients were stratified based on the risk of recurrence after nephrectomy. Recurrence rate and survival outcomes were assessed. RESULTS: The cohort (n = 439) had a median age of 64 years, 66.1% were male, and 76.5% had clear-cell histology. The median follow-up time from nephrectomy was 39.3 months overall, 41.0 months for intermediate-high-risk patients (n = 377; 85.9%) and 24.1 months for high-risk patients (n = 62; 14.1%). For intermediate-high- and high-risk patients, respectively, 68.4% and 56.5% had ≥1 medical oncologist visit after nephrectomy. Of 260 patients with documentation of postoperative imaging assessments, 72% were ordered by medical oncologists, and the median time from initial nephrectomy to the first scan was 110 days (intermediate-high-risk) and 51 days (high-risk). Provider-documented recurrence occurred in 223 (50.8%) patients, of whom 41.7% had ≥1 medical oncologist visit before the recurrence. Three-year disease-free survival (DFS), and overall survival rates were 49.4% and 80.8% (all patients): 27.7% and 64.7% (high-risk); and 52.9% and 83.3% (intermediate-high-risk). CONCLUSIONS: Our study reports low DFS after nephrectomy for patients with intermediate-high- and high-risk RCC. Subsequent approval and use of new and newly approved adjuvant therapeutic options could potentially delay or prevent recurrence.
