Purpose:
We evaluated the outcome of patients with locally recurrent renal cell carcinoma treated at our university.
Materials And Methods:
We retrospectively analyzed 16 cases of locally recurrent renal cell carcinoma in the renal fossa treated with surgical resection alone or in combination with biological therapy.
Results:
Complete resection was possible in 15 patients of whom 3 had positive surgical margins. Of the 12 patients with negative margins 6 are free of disease while the 3 with positive margins had involvement of a remaining ipsilateral adrenal gland and distant metastasis. Of all 16 patients 12 are alive a median of 23.5 months after the diagnosis of locally recurrent renal cell carcinoma. Of those treated with the combination of biological therapy and surgery 50% have no evidence of disease compared to 25% of those treated with surgery alone.
Conclusions:
Long-term survival can be achieved with an aggressive surgical approach. Incomplete resection or positive surgical margins are associated with a high risk of local or distant failure, and combined treatment with immunotherapy and surgery may offer a benefit compared to surgery alone.
