Neurosurgeons have been using lasers to trade brain cancer since two thousand nine
But now they say the technique may also allow them to deliver chemel therapy drugs directly into the brain
The cy is getting passed the protect of loolood brain barrier
Which does its jobs
So well
It also keeps potentially lifesaving chemmtherapy y drugs
Cathy smith has a very in cancer that spread to her brain
A type of brain cancer called bleo bless stoma
And there were a believe three tumors at that time
And i was not at all happy about those twitter
Which was treated with laser therapy doctors insert a tiny probe into the brain
Directly to the cancer
Where it burns up the tumor from the inside out
According to washington in university neurrosurgery professor eric lute heart during the procedure
It was discovered the therapy had an unintended effect on the blood brain barrier
We were basable able
Able show so that this blood brain barriers broken down for around four weeks after to this laser therapy so not only are you know like killing the tumor
You're actually opening up a window of opportunity to deliver now various drugs and bmicals and therapy to get otherwise not get there in kath's case
A owererable stem m chemotherapy drug called ducs a bbisson
Which has been notoriously hard to get past the barrier by breliver directly into her brain
I think what's really interesting is that the blood brain barriers at a two way street
But by breaking it down
You can get things into the brain
But also by breaking it down
That to comical for erbrain out into your circulation to your perpheral uh system
Which includes bstoma tustem and the immune system helps spite cancer
The procedure is dangerous
A compromise blood brain barrier puts the brain at risk
But so far it's worked ked well for stomate patients diagnosed with a gliof blast stoma tumors usually survived just fifty months after diagnosis
But smith has been fighting her cancer since two thousand and nine kind makes you smile
When they say oh
You're a good candidate for or something new
And so got worked into that study or got worked into that
And it did work out
Beautifully
The team of neurosurgeons from washington university and saint lewis are hoping to publish a more formal report on their work later
This year
