Old cancer drug gets fresh look

摘要

When Dave de Bronkart was diagnosed with advanced kidney cancer in 2007, he learned about a treatment called high-dose interleukin-2 (IL-2) that fires up the body's immune system to fight the disease. The response rate was not great - tumours shrank in only about 15% of patients. And as many as 4% of people died from the treatment. But some of those who responded survived for years or even decades.
