study of patients with metastatic and/or advanced renal cell carcinoma, treated with sunitinib/axitinib.

Conditions: Carcinoma; Renal Cell

Summary: research questions: to understand the clinical outcomes of patients treated with sunitinib in first line and axitinib in second line in a real world setting as therapies for metastatic and/or advanced renal cell carcinoma (mrcc). primary objective: 1. what is the progression free survival (pfs) of patients treated in first line with sunitinib, and stratified by memorial sloan-kettering cancer center / international metastatic renal cell carcinoma database consortium (mskcc/imdc) risk category (favourable, intermediate, poor)? 2. what is the progression free survival (pfs) of patients treated in second line with axitinib, and stratified by mskcc/imdc risk category (favourable, intermediate, poor)?
