Renal fossa recurrence after nephrectomy for renal cell carcinoma: prognostic features and oncological outcomes

Abstract

Renal fossa recurrence is a rare event after RN for RCC and portends a poor prognosis, even in the absence of synchronous metastases. Development of iRFR is associated with advanced stage and aggressive tumour biology. Patients who underwent primary locally directed therapy had superior CSS compared with those treated with expectant management, supporting the use of aggressive local treatment in carefully selected patients with RFR. Future research is needed to determine the optimum role and sequencing of combined therapy in patients with this rare entity.
