Pazopanib is approved in Latin America as first targeted therapy for patients with metastatic renal cell carcinoma (mRCC).
A retrospective chart review of adult patients with mRCC who initiated pazopanib as first targeted therapy between January 2011 and March 2016 was conducted among oncology care centers in Argentina, Brazil, Chile, Colombia, and Mexico. Patient characteristics, treatment patterns, overall survival (OS), progression-free survival (PFS), and adverse events were summarized.
A total of 156 charts of patients with mRCC receiving first-line pazopanib were reviewed (29, 54, 27, 28, and 18 patients from Argentina, Brazil, Chile, Colombia, and Mexico, respectively). The mean age at initial mRCC diagnosis was 61.6 years, 73.7% were male, and 51.3% were Hispanic. The median dose of pazopanib was 800 mg and the median time from initial mRCC diagnosis to pazopanib start was 2.2 months. The median time on treatment was 10.0 months. At the time of data extraction, 16.7% of patients remained on pazopanib, with clinical progression listed as the main reason for discontinuation. Subsequent therapy was received by 25.6% of patients; the most common were everolimus (9.6%) and axitinib (5.8%). Overall, median PFS and OS were 10.8 and 16.9 months, respectively, and varied across countries. The most common all-grade adverse events were diarrhea (44.9%), asthenia/fatigue (43.6%), and nausea (28.8%).
Pazopanib was used for first-line mRCC treatment in a clinically diverse patient population across Latin America. Real-world PFS and tolerability were similar to clinical studies of pazopanib.
