Jennifer Mathews: Nine years ago, Roberta Hanley was diagnosed with breast cancer. She had a mastectomy, but it wasn't enough. Roberta Hanley: Three years later, it returned with a vengeance. It had spread to my lungs and to my bones. Jennifer Mathews: Aggressive therapy and a bone marrow transplant kept her cancer-free until two years ago. Roberta Hanley: The cancer returned, and it came back in my brain this time, which I thought for sure, I'm gone. Jennifer Mathews: Then, she met Dr. Dino Stea and received a new drug, called RSR-13. It delivers oxygen to tumors just before radiation. Dino Stea: Radiation would be like a flame and without oxygen, the flame extinguishes. Jennifer Mathews: With RSR-13, the radiation works better. Dino Stead: All we're doing now is trying to make that radiation go a step further to get more bang for the buck. Jennifer Mathews: It appears to be working. Sixty patients received the drug and survived 50% longer than controls. Roberta Hanley: Okay! I am still in the game. Jennifer Mathews: Without the drug, Roberta was given six months to live. That was two years ago, and doctors tell her there's still no sign of the cancer. Roberta Hanley: I'm alive, and I'm going to take each day, one day, one night a time. Jennifer Mathews: She is ready to face whatever life brings, and tonight that means keeping a steady hand. This is Jennifer Mathews reporting.
