For the first time, doctors have breached the human brain’s protective layer to deliver cancer-fighting drugs. Experts said the experimental technique used at Sunnybrook Health Sciences Centre was exciting because it meant doctors might be able to give cancer patients potent drugs that otherwise would not work.
The same non-invasive method could also be used for other brain diseases, such as dementia and Parkinson’s. But many more safety studies are needed, they say. Animal trials have produced some results, but it is not yet clear whether the treatment would work or have side-effects. Six to 10 more patients will undergo the same procedure as part of a trial.
