Osseous metastases secondary to renal cell carcinoma

Abstract

We present the distribution of metastases and clinical course of 252 patients with osseous metastases secondary to renal cell carcinoma. Symptoms of the metastases were the presenting complaint in 48 per cent of patients (including 37 with pathologic fractures); the axial skeleton was the most commonly involved site. Despite earlier reports that nephrectomy lengthened survival for patients with osseous metastases, our data showed this to be true only for patients with a solitary osseous metastasis. Patients with multiple osseous metastases had survival rates no better than patients with soft tissue or mixed lesions-whether or not nephrectomy was performed.
