Studies in animals have raised concerns that tumors may grow faster after the anticancer drug sunitinib is discontinued. But oncologists and physicists who collaborated to analyze data from the largest study of patients with kidney cancer convincingly demonstrate that such tumor acceleration does not occur in humans. The findings, publishing online on February 7th in the Cell Press journal Cell Reports, suggest that sunitinib does not cause lingering risks for patients after their treatment ends.
