Radio Waves Fire Up Nanotubes Embedded in Tumors, Destroying Liver Cancer

Cancer cells treated with carbon nanotubes can be destroyed by noninvasive radio waves that heat up the nanotubes while sparing untreated tissue, a research team led by scientists at The University of Texas M.D. Anderson Cancer Center and Rice University has shown in preclinical experiments. In a paper published in the journal Cancer, the researchers demonstrated that the technique completely destroyed liver cancer tumors in rabbits. There were no side effects noted. However, some healthy liver tissue within 2 to 5 millimeters of the tumors sustained heat damage due to nanotube leakage from the tumor.
"These are promising, even exciting, preclinical results in this liver cancer model," said lead investigator Steven Curley, M.D., of M.D. Anderson. "Our next step is to look at ways to more precisely target the nanotubes so they attach to, and are taken up by, cancer cells while avoiding normal tissue."
