The drug, called combretastatin, works by destroying the developing blood vessels which tumors generate to supply themselves. Used on its own, however, it leaves a 'rim' of cancerous cells at the edge, allowing the disease to return.
Radiation therapy completes the attack on the tumour by ensuring all the leftover cells are killed off. Antibodies with radioactive 'warheads' home in on the disease cells and destroy them.
thanks for that -- I had remembered seeing an article about a drug that killed off all but the outer ring of cancer cells --but I didn't remember they had found a solution by adding radiation. I wonder what the status of the drug testing is to date?
