Patients with metastatic papillary renal cell carcinoma (RCC) who may benefit from sunitinib therapy (tx): Results from an international metastatic RCC database. Academic Article uri icon


  • 486 Background: The VEGFR inhibitor sunitinib is a standard tx for metastatic clear cell RCC. Data on the activity of sunitinib in metastatic non clear cell RCC, is limited by small or heterogeneous (mixed histology or targeted therapies) studies, that revealed a lower antitumor activity than in patients with clear cell histology. We aimed to analyze the activity of sunitinib in a large international cohort of patients with metastatic papillary RCC, and to characterize patients who may benefit for this therapy. Methods: Records from metastatic papillary RCC patients treated with sunitinib in 10 centers across 3 countries were retrospectively reviewed. Univariate and multivariate analyses of association between clinicopathologic factors and clinical outcome were performed using Cox regression. Results: Between 2004-2013, 74 patients (median age 60, 68% male) with metastatic papillary RCC were treated with sunitinib. 78% had a prior nephrectomy. HENG risk was good 11%, intermediate 56%, and poor 33%. 21% we...
