SIUH Offers New 5-Day Breast Cancer Therapy

August 3, 2011 By Bio-Medicine.Org

NEW YORK, Aug. 3, 2011 /PRNewswire/ — A new type of radiation
therapy for early-stage breast cancer is available at Staten Island
University Hospital that cuts down on treatment time while sparing
healthy tissue.

When a breast cancer patient undergoes a lumpectomy to remove a
cancerous tumor, it’s often followed by radiation therapy.
Traditional radiation therapy can take an average of five weeks.
But using the SAVI breast brachytherapy applicator allows patients
to complete their radiation treatments in only five days.

SIUH is the first hospital in New York State to be recognized as
a Center of Excellence for the SAVI treatment.

The SAVI applicator is made up of a slim bundle of soft and
flexible catheters. A breast surgeon makes a small incision in a
patient’s breast and places the device in the lumpectomy
cavity.

Once inside, the catheters are expanded to conform to the site.
Each catheter individually radiates the tissue surrounding the
lumpectomy cavity from the inside out.

“The reason to use a multi-catheter device is that we can
control the dose of radiation for each of the catheters, so the
catheters that are closest to the skin can get less radiation,”
explained Dr. Cynara Coomer, chief of Breast Surgery at SIUH and
director of The Comprehensive Breast Center.

“The catheters that are closest to the breast tissue can get
more radiation. So, the tissue that really needs to be radiated can
be radiated with the highest dose and that means less exposure to
the skin, the chest wall, heart and lungs.”

The SAVI applicator stays in place throughout the week-long
treatments. A portion of the end of each catheter remains
accessible outside the patient’s breast and is secured with
dressing and a sports bra.

Treatments are delivered twice a day, six hours apart. For each
session, a tiny radioactive seed is placed inside each catheter by
a computer-controlled machine. The radiation source is removed
after ea
