    Abstract:
    BACKGROUND: A retrospective, registry-based analysis to assess the outcomes of metastatic renal cell cancer (mRCC) patients treated with sunitinib and sorafenib who developed dermatologic adverse events was performed. PATIENTS AND METHODS: Data on mRCC patients treated with sunitinib or sorafenib were obtained from the Czech Clinical Registry of Renal Cell Cancer Patients. Outcomes of patients who developed hand-foot syndrome (HFS) of any grade and/or grade 3/4 rash during the treatment were compared with patients without HFS and no, mild, or moderate rash. RESULTS: The cohort included 705 patients treated with sunitinib and 365 patients treated with sorafenib. For sunitinib, the median overall survival (OS) was 43.0 months versus 31.0 months (P = 0.027) and median progression-free survival (PFS) 20.8 months versus 11.1 months (P = 0.007) for patients with versus without dermatologic toxicity, respectively. For sorafenib, the median OS and PFS were 27.9 and 24.6 months (P = 0.244), and 12.2 and 8.8 months (P = 0.050), respectively. In multivariable Cox regression, the skin toxicity was significantly associated with longer OS in the sunitinib cohort. CONCLUSION: The presence of skin toxicity is associated with improved OS and PFS in patients with mRCC treated with sunitinib.
