Kid-Safe Chemo Protects Hearts
April 21, 2010
MIAMI, Fla. (Ivanhoe Newswire) -- Kids
are winning the battle against cancer. The survival rate is now 90 percent,
but the powerful treatments come at a price. Researchers may have a solution
to kick cancer and protect the rest of the child’s growing body.
Daniela Leon battles cancer with a style all her own. But she admits, it
“I remember just looking in the mirror and thinking, ‘I have cancer?’”
Daniela told Ivanhoe.
Eight months ago, she was diagnosed with a childhood kidney cancer called
“I wasn’t going to have pity for myself," Leon told Ivanhoe. "There was no
room for that. Whatever I had to do to cure this needed to get done."
Chemotherapy and other drugs had a dramatic effect.
“Her tumors got smaller," John Goldberg, M.D., Assistant Professor of
Clinical Pediatrics at the University of Miami Miller School of Medicine in
Miami, Fla., told Ivanhoe. "The tumors in her lungs went away. They
evaporated. Then, low and behold, we do an echocardiogram, and her heart
function has gotten worse.”
It’s a common chemo side effect. Studies show
20 years after treatment, childhood cancer patients’ risk of death from
heart problems is more than eight times greater than those not treated for
“Children that are 30 year survivors have about a 15 times greater chance of
getting congestive heart failure,” Steven Lipshultz, M.D., Chairman of the
Department of Pediatrics at the University of Miami Miller School of
Medicine, told Ivanhoe.
To reduce that risk, doctors developed a new regimen -- adding a drug called
DZR to the standard chemo. Five years later, kids treated with DZR showed
much less heart damage but still benefited from the chemo.
Now, Leon gets treatment that fights cancer and protects her heart.
“In short, it allows us to continue giving her the chemo that she needs to
survive,” Dr. Goldberg said.
So she can keep fighting for a healthier future.
Childhood cancer survivors also have a 60 percent higher risk of developing
more cancer, brain tumors or depression as adults.
