For two decades, doctors have followed an ethically-established agreement about the appropriate use of artificial nutrition and hydration (ANH) for patients who are seriously ill or in a persistent vegetative state.

The study indicates that pretreatment with a drug that blocks blood-vessel growth might improve the effectiveness of cancer-killing viruses.
