NanoKnife™ Kills Cancerous Cells Without Harm to Healthy Tissue
ATLANTA (January 19, 2010) — Piedmont Hospital is increasing the
treatment options available to cancer patients by offering a new
technique that physicians can use to kill cancerous tumor cells without
harming nearby healthy tissue.
“Piedmont Hospital is the sixth facility in the United States to offer
NanoKnife™ to cancer patients outside of clinical trials,” said Steven
Citron, M.D., interventional radiologist. “It provides a treatment
option to patients who have no other alternatives due to the location of
While other techniques work with intense heat or cold to kill cancer
cells, NanoKnife™ uses electrical pulses that minimize damage to
surrounding nerves, blood vessels and lymphatic systems. During a
procedure, a physician inserts a needle-like probe into a tumor, which
then fires off a series of electrical pulses into the cancerous cells.
The pulses open up the cancer cell membrane and, when enough electricity
is applied, the cells do not close and the tumor dies. The surrounding
blood vessels and lymphatic systems can then assist in removing the dead
cells from the body.
“NanoKnife™ is a tremendous leap forward for addressing tumors in
critical organs such as the liver, kidneys or lungs,” said Marty T.
Sellers, M.D., a multi-organ transplant specialist and medical director
of Piedmont Hospital's liver cancer service. “Other techniques use
temperature extremes to kill a tumor, but that approach can not only
cause serious harm to surrounding healthy tissue but may also leave a
tumor adjacent to a large vessel inadequately treated.”
