Cancer seeing glasses
Doctors at Washington University in St. Louis
have created cancer-seeing glasses for use during surgery.
The glasses are a lot like Google Glass, but instead of
seeing the internet, surgeons can see lit up cancer cells. They have only been
used on ten patients, and those patients have breast cancer or melanoma. Doctors hope someday they can use this technology on all
cancer patients.
They may look like something out of a sci-fi movie, but the
glasses have the potential to help save lives.
"It really has the ability to revolutionize the way
that we take care of cancer patients," said Dr. Ryan Fields.
The glasses help surgeons Fields with the Siteman Cancer
Center see more precisely what they are working on, by recognizing a dye that's
injected into a person's vein.
In a video from a recent lymph node removal surgery at
Siteman you can see the incision area before the surgeon puts the glasses on.
Then while wearing the glasses, the doctor sees a blue glowing image. That's
the lymph node they're going after.
"The area that lights up kind of like what you would
see on a radar. That's the most intense spot that dye was picked up," said
Fields. But the glasses are only one part of the technology being
developed. Washington University Professor Dr. Sam Achilefu is creating a new
dye that would be injected through the vein and detect cancer cells anywhere in
the body. "You can kind of see the edge of the cancer by wearing
the goggles and administering this contrast agent that he's developing,"
said Fields.
Looking through the glasses a surgeon could see exactly
where the cancer cells end and where the healthy tissue begins, decreasing the
chances of a patient having to revisit the operating room for a second surgery.
"The real hope is that whatever we do impacts the patient
in a very positive way," said Fields. The developer is still waiting for the new dye to be
approved by the FDA. That will be followed with a clinical trial using the dye
and the glasses. It should all happen in the next six months.
