This population-wide retrospective, non-interventional registry study assessed changes in overall survival (OS) and factors influencing OS in Norwegian patients with renal cell carcinoma (RCC).
Two population-wide health registries were used to identify all RCC patients with (mRCC) or without metastases diagnosed before (2002-2005) and after (2006-2008 and 2009-2011) introduction of targeted therapies.
