Prescribing Preferences in the First-Line Treatment for Patients With Metastatic Renal Cell Carcinoma in the United States

Sunitinib and pazopanib were the most preferred agents for first-line mRCC treatment. Sunitinib preference was driven by perceptions of efficacy, and pazopanib was preferred for its perceived tolerability and efficacy similar to sunitinib. With varying clinical scenarios, initial pazopanib prescribers were more likely to maintain pazopanib and alter dosing; sunitinib prescribers were more likely to switch therapy.
