Vared Sterns, Johns
Hopkins: Chemotherapy Directly Through Nipple Breast Cancer Treatment
Shows Great Promise

There's some promising
news about breast cancer treatment. In clinical trials at Johns Hopkins
Cancer Center in Baltimore, Maryland, doctors report they successfully
pumped cancer-fighting medicine directly into a breast tumor. Early
results show the treatment not only kills the tumor, but spares the
patients disfiguring surgery and the side effects of more radical
treatments.
The earliest stages of breast cancer are usually discovered during a
mammogram. Right now, the standard treatment when tumors are found is
surgery, followed by radiation therapy and then hormone treatment. Some
women who have a high risk of getting breast cancer even opt to have
mastectomies - the surgical removal of one or both breasts - just to
reduce their risk.
At Johns Hopkins Cancer Center in Baltimore, one oncologist has been
studying a less radical approach.
"Since most cancers originate within the breasts and the cells that line
the milk ducts within the breasts, can we possibly eliminate those
dangerous cells, and by doing so, eliminate breast cancer?" asks Dr.
Vared Sterns.
The idea is simple. Give a small concentration of a chemotherapy drug
directly through the patient's nipple and into the milk ducts where
cancer cells or even pre-cancerous cells are forming. The entire
procedure takes about 30 minutes. In clinical trials, researchers found
this technique was more effective and less toxic than the conventional
practice of administering chemotherapy through the vein.
"What we found was that the concentration of the drug within the breast
was very, very high, while the concentration of the drug within the
blood system was very low," said Sterns.
With
conventional chemotherapy, the opposite was true: Drugs administered
through the vein concentrated in the blood system and but were less
concentrated where they were most needed - in the breast. The clinical
trials have been so promising that this type of treatment might
eventually become the standard for patients with very early stages of
breast cancer or those who are at risk of developing it.
"It is my hope that the treatment can be delivered in just your usual
mammogram suite. This has been done in our study quite easily on an
outpatient basis. It doesn't take very long. It's not painful," said
Sterns.
She likens this procedure to a colonoscopy. If there's a polyp, the
doctor removes it before it can become cancerous.
Dr. Sterns said researchers need to find out how much of the drug is
needed and how often it should be administered to rid the breast of
cancer. She estimates that work will take another 10 years. Then, if
this procedure is as promising as it seems, it may become standard
treatment for patients with early stage breast cancer. |
