North Shore Radiation Therapy is First on Long Island to Treat Patients with the Contura Applicator for Partial Breast Radiation

Powerful new approach for the treatment of breast cancers in only five days

(Huntington, NY) - North Shore Radiation Therapy has become the first cancer center on Long Island to treat breast cancer patients with a revolutionary new technique using the Contura device from Senorx.

The Contura Brachytherapy procedure is a partial-breast radiation treatment that allows breast cancer patients requiring radiation therapy after a lumpectomy to be treated in five days, rather than six to seven weeks for whole-breast irradiation.

“Brachytherapy is from the Greek word meaning ‘close’ or ‘internal,’ referring to a way of delivering treatment from inside rather than outside,” explained Maged Ghaly, M.D., “By targeting treatment from inside the breast, we can complete radiation treatment in 5 days, allowing patients to return more quickly to their day-to-day lives.”

Radiation therapy is given to most patients who have a lumpectomy for breast cancer, to kill cancer cells or prevent them from reproducing or spreading, reducing the risk of recurrence. Whole breast irradiation uses a radiation source outside the body to treat the cancer site, typically involving daily treatments for six days per week over a six- to seven-week period.

Many breast cancer patients may be appropriate candidates for alternatives to whole breast radiation treatment known as partial breast irradiation or breast brachytherapy, a technique for delivering internally targeted radiation. Breast brachytherapy delivers radiation to the breast tissue surrounding the lumpectomy cavity rather than to the entire breast.

The Contura is a small balloon-based device implanted into the breast to treat the tissue surrounding the cavity left by lumpectomy surgery. After being inserted, the balloon is inflated and filled with saline; vacuum is used to help the balloon fit closely within the often irregularly shaped lumpectomy cavity. Then a radiation seed is sent through five separate “lumens” or channels inside the balloon, allowing the radiation dose to be “contoured” to reach the targeted area.

“The dose is directed by where the seed sits in the balloon, allowing us to concentrate the radiation dose on the tumor area,” explained Heather Zinkin, M.D. “If the seed were too close to the skin in channel one, we might place the seed in channels three or four for a longer time than in channel one.”

Before the introduction of Contura in 2007, balloon brachytherapy was available with only a single channel for delivery of the radiation seed. Some patients who were possible candidates for the therapy were excluded because the location of the lesion relative to their breast size did not allow appropriate placement of the radiation seed to minimize radiation dose to the skin, chest wall or ribs.

Contura Multi-Lumen Balloon Brachytherapy was developed to address this problem by using five separate channels to place the radiation seed. It also employs vacuum suction to help the balloon fit closely within the often irregularly shaped lumpectomy cavity, so the targeted areas receive the prescribed therapeutic dose.

“The multiple channels of the Contura and its vacuum feature help the physician to shape or contour the radiation dose to obtain a more optimal result,” said Richard Byrnes, M.D., “We are able to better target the radiation to the areas in most need of treatment.”

Since 1988, North Shore Radiation Therapy has provided premier radiation therapy services to Suffolk County. The center offers 3-D Conformal Radiation Therapy, IMRT (Intensity Modulated Radiation Therapy), IGRT (Image Guided Radiation Therapy), SRS (Stereotactic Radiosurgery), RapidArc, Prostate Brachytherapy, Mammosite, Contura and Gynecological Brachytherapy. North Shore Radiation Therapy is the most experienced in prostate cancer treatment in Suffolk County. The center is staffed by board certified physicians, and highly trained clinicians with expertise in utilizing the most advanced radiation therapy technology. Located at in Huntington, and Smithtown, New York, the center is open Monday through Friday, and accepts all insurance plans. Appointments can be made by calling (631) 427-2273.

NEW Treatment for Breast Cancer

Partial Breast Radiation Therapy with Brachytherapy Using a Multicatheter Balloon

Contura - Multi-Lumen Balloon Applicator

North Shore Radiation Therapy is the FIRST ON LONG ISLAND to offer patients this NEW INNOVATIVE BREAST CANCER TREATMENT in ONLY 5 DAYS. This new breast cancer radiation therapy option is through internal radiation. This is commonly known as breast brachytherapy.
This is done by placing a radiation source inside the body. This process has three important advantages:

It places the radiation inside the lumpectomy cavity (the space left when a tumor is removed). The radiation is targeted to the area where cancer is most likely to recur.

Radiation is delivered from the within the cavity, limiting the amount or radiation to healthy surrounding tissue, thereby reducing the potential for side effects to occur.

The therapy can be completed in 5 days in an out patient setting.

A Simple Way To Deliver Radiation From The Inside

The Contura is a new minimally invasive method of delivering internal radiation therapy following a lumpectomy for breast cancer. Therapy is given on an outpatient basis, so there is no need for a hospital stay and the treat can be completed in 5 days
The Contura is a single small balloon catheter than (A) fits inside the tumor resective cavity (the space left after the surgeon has removed the tumor). A tiny radioactive seed (B), connected to a machine called an afterloader (C), is inserted into the balloon and delivers the radiation therapy.

This focuses the radiation dose on the area of the breast at highest risk for tumor recurrence. Radiation therapy with this device is preformed over a period of 1 - 5 days. When used alone, patients typically receive treatment twice a day for 5 days.
If your doctor feels that external beam radiation is appropriate for you, the Contura may also be used a boost therapy in conjunction with external beam radiation. A boost is a procedure that delivers additional therapy directly to the area of the breast at highest risk for tumor recurrence.
The safety and effectiveness of the brachytherapy as a replacement for whole breast irradiation in the treatment of breast cancer has not been established. Please consult with your Radiation Oncologist to determine if you are an appropriate candidate for treatment with the Contura.
