BACKGROUND: Patients with advanced renal cell carcinoma in routine clinical practice can differ considerably from those in phase III studies.
PATIENTS AND METHODS: PREDICT (Patient characteristics in REnal cell carcinoma and Daily practICe Treatment with sorafenib) was a prospective, noninterventional study of open-label sorafenib for the treatment of advanced RCC conducted in 18 countries. Patient characteristics, therapy duration, tumor status, and tolerability were assessed at baseline and during routine follow-up.
RESULTS: Overall, 2599 patients were evaluable for safety and 2311 for efficacy. The diverse population included patients with brain metastases (5%), non-clear-cell histologies (17%), high Memorial Sloan-Kettering Cancer Center risk score (11%), poor Eastern Cooperative Oncology Group performance status (PS ≥ 2, 29%), and patients with no previous nephrectomy (16%) or no previous systemic therapy (37%). The median duration of sorafenib therapy was 7.3 months and was similar in clinically relevant subgroups (eg, patients with PS 2, brain metastases, or concomitant hypertension or diabetes [range, 6.7-7.0 months]). The median duration of therapy was shorter for patients with PS 3 or non-clear-cell histologies (4.6 and 4.8 months, respectively). The most common drug-related adverse events were hand-foot skin reaction (20%), diarrhea (17%), and rash (8%).
CONCLUSION: Sorafenib was generally well tolerated and provided clinical benefit in a large, diverse population of patients with advanced RCC treated in routine clinical practice.
