A highly personalized medical technique is allowing patients with advanced kidney cancer to live nearly three times as long as they normally do. In an experiment involving 21 patients, around half lived more than two and half years after diagnosis with kidney cancer that had begun to spread. Five patients are alive after more than five years.

"That seems to be out of proportion with what you would expect for any commercial therapy and longer than what you would expect from patients with similar prognostic variables," says Robert Figlin, an oncologist at Cedars-Sinai Samuel Oschin Comprehensive Cancer Institute in Los Angeles, who is leading the study.
