That…sounds like some seriously sci fi medicine. I’m a bit skeptical that the AP has this quite right; I want to look more into the actual mechanisms here.
Doctors are reporting improved survival in men with advanced prostate cancer from an experimental drug that delivers radiation directly to tumor cells.
Few such drugs are approved now, but the approach may become a new way to treat patients with other hard-to-reach or inoperable cancers.
The study tested an emerging class of medicine called radiopharmaceuticals, drugs that deliver radiation directly to cancer cells. The drug in this case is a molecule that contains two parts: a tracker and a cancer-killing payload.
Trillions of these molecules hunt down cancer cells, latching onto protein receptors on the cell membrane. The payload emits radiation, which hits the tumor cells within its range.
“You can treat tumors that you cannot see. Anywhere the drug can go, the drug can reach tumor cells,” said Dr. Frank Lin, who had no role in the study but heads a division at the National Cancer Institute that helps develop such medicine.
