Researchers from University
of Texas M.D. Anderson Cancer center
and Rice University combined two technologies in
order to fight cancer in rabbits.
The findings were published online by the journal Cancer.
Dr. Steven Curley, an M.D. Anderson surgical oncologist and
the paper's senior author, said Thursday that he hopes this method tried
successfully on rabbits “will be a very useful tool to safely and efficiently
treat a lot of types of cancer."
His research was based on using nanotubes heated by radio
waves to kill cancer cells.
The nanotubes are part of a family of carbon molecules named
fullerenes, and they were discovered by Rick Smalley who had been awarded for
this with 1985 Nobel Prize.
The other technology, targeted radio waves, is a recent
discovery of John Kanzius, an M.D. Anderson leukemia patient and retired Pennsylvania radio and
television station owner. After diagnosed with leukemia and suffering from
chemotherapy, Kanzius thought that it must be a better way to fight the cancer
and he might able to find it. He used his knowledge as radio engineer and
developed in his garage a radio-frequency generator. He brought his discovery
to Dr. Steven Curley with the suggestion that copper should be used as target
agent.
But Curley and his team preferred to use carbon nanotubes.
The result was astonishing. They injected directly the rabbits’ tumor with a
solution of single-walled carbon nanotubes, and then they exposed the targeted
area to two minutes of radio frequency treatment. The cancer cells’ membranes, protein and even
DNA were destroyed 100 percent by this localized hyperthermia.
Officials from the American Cancer society found this
discovery truly useful, but they mentioned that still there is need for further
study and it will take at least five years before this method will be tried on
humans.
