Radio waves used to destroy liver tumors

HOUSTON, Nov 1, 2007 (UPI via COMTEX) -- Texas researchers say animal

tests show liver tumors can be destroyed by inserting carbon nanotubes

that are heated with non-invasive radio waves.

 

The report, posted online in the journal Cancer, said the technique

destroyed liver cancer tumors in rabbits. Researchers from The

University of Texas M.D. Anderson Cancer Center and Rice University said

the next step is to find ways to more precisely target the nanotubes to

avoid all normal tissue.

 

Dr. Steven Curley, a surgical oncologist at M.D. Anderson who was senior

author of the report, said researchers are trying to bind the nanotubes

to antibodies, peptides or other agents that target molecules expressed

on cancer cells.

 

In the liver cancer experiment, a solution of single-walled carbon

nanotubes was injected directly into the tumors. Four treated rabbits

were then exposed to two minutes of radio frequency treatment, resulting

in thermal destruction of their tumors, researchers said Thursday in a

news release.

 

Carbon nanotubes are hollow cylinders of pure carbon that measure about

a billionth of a meter across.
