[Late recurrence of renal cell carcinoma: report of three cases].
A 70-year-old woman underwent a left radical nephrectomy. The pathological examination revealed renal cell carcinoma (RCC), grade 1 and no lymph node metastasis. She suffered a recurrence in the renal fossa 11 years after the operation. The doubling time of the recurrent lesion was calculated to be very long for the cancer; about 1.3 years. Another case was in a 61-year-old woman, who underwent a right radical nephrectomy. The pathological examination revealed RCC, grade 1 with vascular invasion and no lymph node metastasis. Eleven years postoperatively she developed metastases in both lungs. The other case was in a 39-year-old woman, who underwent right radical nephrectomy. The pathological examination revealed RCC, grade 1 with vascular invasion and no lymph node metastasis. Eight years postoperatively she developed a recurrence in the left kidney. The doubling time of the recurrent lesion was about 0.9 year. All three patients responded to conservative therapy including interferon. Taking those doubling times into account, the recurrent lesions in the first and third cases seemed to have been growing very slowly and not rapidly immediately before clinically evident recurrence. Patients with a low grade RCC must have life-long followup.
