A Study to go Back Into Records and Observe How People With Metastatic Renal Cell Carcinoma (mRCC) Who Received a Medicine Called Sunitinib Responded to This Medicine.

This study is designed as a local, non-interventional, retrospective, registry-based study to observe treatment response in patients with metastatic Renal Cell Carcinoma with Sunitinib First-Line Therapy based on data extracted and analyzed from the RCC Registry. The annual disease burden in contributing centers to RCC Registry is approximately 100 patient/center, the treatment of an average of 250 patients per year is continued in the centers. Therefore, it is estimated that information of approximately 400 eligible patients who were registered in RCC Registry from 2019 to 2022 will be included in the analysis. RCC Registry will be used as the sole data source for this study. For this purpose, no Case Report Forms (CRFs) or Data Collection Tools (DCTs) will be utilized, but the RCC Registry database will be used directly. Eligible patients' data will be anonymized and extracted for analysis by the registry owner, for this study.
