Quality of life predicts progression-free survival in patients with metastatic renal cell carcinoma treated with sunitinib versus interferon alfa

In a randomized phase III trial, sunitinib was associated with significantly superior progression-free survival when compared with interferon alfa as first-line therapy in patients with metastatic renal cell carcinoma. This article investigates whether baseline quality of life and demographic and clinical variables were predictive for progression-free survival.
