简要总结
This study is a multicenter, non-interventional, retrospective, medical chart review of patients with metastatic renal cell cancer(mRCC) treated with avelumab plus axitinib as a first-line therapy in Japan between 20 December 2019 and 20 December 2020. All decisions regarding clinical management and treatment of the participating patients were made by the investigator as part of standard care in real-world clinical setting and were not contingent upon the patient's participation in the study. Data will be collected if available per study site.
