The Efficacy of Wide Resection for Musculoskeletal Metastatic Lesions of Renal Cell Carcinoma

Background/Aim: This study evaluated the outcome of wide resection for metastatic renal cell carcinoma (RCC) to the bone or soft tissue. Patients and Methods: Thirty patients who underwent surgery for bone or soft tissue metastatic lesions of RCC were retrospectively evaluated. The surgical procedures were wide resection in 14 patients (group 1) and intralesional resection in 16 (group 2). Results: The 3-, 5-, 10-, and 15-year overall survival (OS) was 76%, 48%, 35%, and 23%, respectively, and OS was significantly favorable in group 1. In addition, recurrence-free survival rate was significantly higher in group 1. In the multivariate analysis, intralesional resection was an independent risk factor for poor prognosis. There was no significant difference in surgical time, though intraoperative hemorrhage was significantly larger in group 2. Conclusion: The wide resection of bone and soft tissue metastatic lesions of RCC is a favorable option for controlling local metastasis and improving prognosis.
