Predictors for Recurrences Within One Year Following Radical Nephrectomy for Non-metastatic Renal Cell Carcinomas.

Background/Aim: This study aimed to identify predictors of rapid recurrence following radical nephrectomy for non-metastatic renal cell carcinomas. Patients and Methods: Patients with non-metastatic renal cell carcinoma who underwent radical nephrectomy between 2014 and 2024 at Okayama University Hospital were included. Rapid recurrence was defined as local or distant metastasis occurring within one year after radical nephrectomy, whereas recurrences occurring beyond one year were classified as non-rapid. Results: <0.001). Conclusion: Microscopic venous invasion and tumor size of 60 mm or larger were identified as independent predictors of rapid recurrence following radical nephrectomy for non-metastatic renal cell carcinoma.
