Management of locally recurrent renal cell carcinoma after partial nephrectomy.

While partial nephrectomy can provide effective treatment for selected patients with renal cell carcinoma, postoperative local tumor recurs in approximately 10 per cent of the cases. We describe 4 patients in whom tumor recurred in a solitary renal remnant after partial nephrectomy for renal cell carcinoma 1 to 6 years previously. The original tumor was pathological stage I in 2 patients and stage III in 2. Neither of the patients with stage I renal cell carcinoma had metastatic disease when locally recurrent carcinoma was noted. A second partial nephrectomy was done in these patients and they are alive 1 and 10 years later. Both patients with stage III renal cell carcinoma also had metastatic disease when locally recurrent carcinoma was noted. One patient died 1 year later and the other is alive 1 year later. Patients who undergo partial nephrectomy for renal cell carcinoma should be followed closely to allow for early detection of local tumor recurrence. When this occurs, secondary surgical treatment may be possible with complete tumor excision and the opportunity for extended survival.
