Surgical treatment of metastatic renal cell carcinoma

The survivals of 174 patients who underwent nephrectomy for renal cell carcinoma were analyzed to evaluate the influence of the surgical treatment of metastases on their prognosis. For 34 of the 174 patients, surgical resections of the metastases were performed concurrently with nephrectomy. For 38 patients, 44 surgical resections of metastases were performed in the follow-up period after nephrectomy. Apparently curative resections of metastases, at the time of nephrectomy or after nephrectomy, were significantly correlated with good survivals after surgery, irrespective of the number of metastatic foci. Aggressive surgical treatment was beneficial in patients with a longer tumor-free period after nephrectomy or with stable disease for about six months after surgical treatment, although this might simply be a reflection of a longer natural disease course in this specific group of patients.
