The association between performance status (PS) and the prognosis of metastatic renal cell carcinoma (mRCC) patients receiving tyrosine kinase inhibitors (TKIs) remains controversial. The aim of this study is to evaluate the prognostic value of PS in mRCC patients treated with TKIs. ⋯ This study suggests that a poor PS is significantly associated with poor prognosis in mRCC patients receiving TKIs.
