High Dose Rate
Brachytherapy (HDR)

What is HDR brachytherapy?

High dose rate brachytherapy (HDR) is a form of internal radiation where high doses of radiation are delivered quickly during an outpatient procedure. In HDR, catheters are placed into the cancer tissue after which a computer driven apparatus, called a remote afterloading device, pushes the radiation source through the catheters to the tumor site. The source remains in place for a few minutes. When the desired dose has been achieved, the remote afterloading device withdraws the radioactive source.

What are the benefits of HDR brachytherapy?

  • Increased dose to the tumor while sparing the surrounding, healthy tissue
  • Quick treatment sessions lasting only a few minutes
  • Delivery in an outpatient setting after which a patient can return home

What is the preparation for HDR brachytherapy?

The exact preparation for the treatment may depend on the site receiving the radiation. The physician and other members of the treatment team will provide each patient with specific instructions prior to treatment.

How long will treatment with HDR brachytherapy last?

Treatment times depend on many factors such as the location, type and size of the cancer. Some HDR brachytherapy treatments are delivered only once, whereas other treatments may require the patient to come in once or twice a day for a period of one or more weeks. Treatment is accomplished in a few minutes.

What are the side effects associated with HDR brachytherapy?

Brachytherapy is usually well tolerated. Side effects are generally specific to the area being treated and may include some tenderness and swelling in that location. Brachytherapy is focused on a smaller area, therefore there may be fewer side effects. A patient who notices changes that are concerning should notify the treatment team.
