A case of metastatic renal cell carcinoma showing complete remission after cytoreductive nephrectomy followed by temsirolimus

Here, we present a case report of a patient with poor-risk advanced renal cell carcinoma who had a complete remission after cytoreductive nephrectomy followed by temsirolimus. A 67-year-old woman was diagnosed with advanced renal cell carcinoma, stage pT3aN2M1 in April 2013. In the Memorial Sloan-Kettering Cancer Center criteria, she had three prognostic factors and was classified into the poor-risk category. After 23 weeks of treatment with temsirolimus, complete remission was achieved. Temsirolimus treatment was discontinued after 23 weeks because of grade 3 toxicity noninfectious pneumonitis. Five months after beginning steroid treatment without temsirolimus, a CT scan showed no new metastatic lesion or progression of disease. This was a very rare case with achievement of a complete remission after cytoreductive nephrectomy followed by temsirolimus.
