This study is a multicenter, non-interventional, retrospective, medical chart review of participants with metastatic renal cell cancer(mRCC) treated with avelumab plus axitinib as a first-line therapy in Japan between 20 December 2019 and 17 October 2022. 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.

The BOR is defined as the best tumor response recorded during the observation period. The definitions of tumor responses are as follows: Complete or PR as the best adjudication result (CR \> PR \> stable disease \[SD\] \> progressive disease \[PD\], not Evaluable \[NE\]) complies with the RECIST tumor assessment guidelines as closely as possible in clinical practice.

Number of Participants With Best Overall Response (BOR) for Primary Lesions
BOR is the best tumor response recorded during observation period.Tumor response are defined as follows:Complete or PR as the best adjudication result (CR \> PR \> stable disease \[SD\] \> progressive disease \[PD\],not Evaluable\[NE\]) in a method complied with RECIST version. 1.1tumor assessment as closely as possible in clinical practice by investigator's judgment.CR:Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR:Atleast 30% decrease in sum of diameters of target lesions,taking as reference the baseline sum diameters.SD:Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD,taking as reference the smallest sum diameters. PD:atleast a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study.In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm.
