Tratamento cirúrgico na recidiva retroperitoneal tardia por carcinoma renal de células claras após nefrectomia radical / Surgical treatment for late renal cell carcinoma recurrence in the renal fossa after radical nephrectomy

ABSTRACT

Late renal cell carcinoma recurrence in the renal fossa is a rare event. This condition occurs in 1 to 2 percent of radical nephrectomies. We reported a late recurrence at the renal fossa about four and half years after radical nephrectomy due to a renal cell carcinoma (RCC) without metastasis elsewhere. Diagnosis in an outpatient follow-up was made during an abdominal computed tomography and we observed a retroperitoneal mass in the renal fossa. The excision at the recurrence area was made through a subcostal transversal incision without any difficulty. After 6 months from this second procedure, there was no evidence of recurrence. The surgical aggressive treatment for late retroperitoneal RCC recurrence is a good method in this rare situation. Abdominal computed tomography must be done during long periods of follow-up for patients with radical nephrectomy for RCC to search for late retroperitoneal recurrences.
