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.
A pill has been shown to help keep certain early-stage, hard-to-treat breast cancers at bay after initial treatment in findings being reported early because they are so promising.
