Background: To elucidate the clinical prognostic factors in patients with metastatic renal cell carcinoma (mRCC) treated with axitinib. Methods: A total of 58 patients were retrospectively analyzed. All patients received axitinib treatment for mRCC at Keio University hospital in Japan. Baseline clinical factors and on treatment adverse events were assessed to predict survival. Results: The median progression free survival (PFS) for axitinib treatment was 10.9 months (95% CI 5.8-13.5), and the median overall survival (OS) from the start of axitinib treatment was 39.8 months (95% CI 25.9-NR), respectively. The PFS (P < 0.0001) and OS (P = 0.0022) were significantly correlated with the International mRCC Database Consortium (IMDC) classification, respectively. The PFS and OS were significantly longer in patients who received longer prior treatment (P = 0.0424 and 0.0067, respectively). On-treatment hypertension, hand foot syndrome and hypothyroidism were associated with longer PFS (P = 0.0002, 0.0055 and 0.0290, respectively). Ontreatment hypertension, diarrhea, and hand foot syndrome were associated with longer OS (P = 0.0004, 0.0036 and 0.0115, respectively). Conclusions: Baseline and on treatment factors are identified as prognostic markers in mRCC patients treated with axitinib. Our findings might be helpful for clinicians to select the best treatment to individual patients.
