Radical surgery for the solitary bony metastasis from renal-cell carcinoma

We carried out excision of a solitary bony metastasis from renal-cell carcinoma in 25 patients in the hope that this would produce a prolonged disease-free interval. Two patients had excisions only, five had amputations and 18 had excision and endoprosthetic replacement. The one-, three- and five-year cumulative survival rates were 88%, 54% and 13%, respectively. There were three complications. One patient developed a local recurrence and three had problems related to the endoprosthesis. We recommend radical excision of a solitary bony metastasis from renal-cell carcinoma to achieve local control of the tumour for the remainder of the patient's life.
