HDRAt Orange County CyberKnife, we strive to help our patients overcome cancer and reclaim their normal lives. We understand how devastating a cancer diagnosis can be for you or a loved one, which is why we’re proud to offer a variety of advanced cancer treatment methods to combat a wide variety of cancers and conditions. In addition to CyberKnife, Hyperthermia, and Clinac cancer treatments, we’re also proud to offer both low and high dose Brachytherapy to our patients.

High Dose Rate Brachytherapy (HDR)

HDR Brachytherapy is an extremely precise method for radiation therapy that’s effective in eliminating cancers of the skin, cervix, prostate, breast, and many other areas. Brachytherapy works by implanting an intense source of radiation directly into the tumor site, delivering high doses of radiation with remarkable precision. HDR treatment is pain-free, delivered through a computer-controlled machine in just two to ten convenient treatments. To place the radiation applicators, we simply use a wire or cable inserted into a catheter that goes into the tumor site. We can remove the catheter between treatments, helping to minimize side effects and impact on your life, and we can vary the positioning of the wire to target cancer of any shape and location.

We offer three forms of HDR Brachytherapy at our facility:

  • Interstitial Brachytherapy: Commonly used for prostate cancer, this method delivers radiation directly into the tissue.
  • Intracavitary Brachytherapy: Often used for breast, cervical, and vaginal cancers, this method delivers radiation from the cavity left behind by a recently removed tumor.
  • Episcleral Brachytherapy: This method attaches a radiation source to the eye to treat melanoma inside the eye.

Low Dose Rate Brachytherapy (LDR)

LDR Brachytherapy uses a similar method to HDR, but it uses a lower dose over a longer period of time. In most LDR treatments, we’ll implant between 50 and 100 radioactive “seeds” directly into the cancerous tissue, delivering a low, continuous dose of radiation to the tumor over the following month or so. After treatment is completed and the seeds lose their radiation, they’ll fade away with the cancerous tissue. Our radiation oncologists uses special computer planning system that uses transrectal ultrasound (TRUS) images to help design and monitor the radioactive seeds over the course of your treatment. LDR Brachytherapy offers a convenient, one-time cancer treatment solution for a variety of conditions including cervical, esophageal, head & neck, and lung cancer, but it’s most commonly used for prostate cancer.

Mammosite/Savi Targeted Radiation Therapy

Women who choose a lumpectomy rather than a full mastectomy need radiation treatment following surgery. APBI is designed specifically to treat early stages of breast cancer quickly and efficiently by delivering radiation directly into the tumor cavity from inside the body. Orange County radiation oncologists work directly with breast surgeons to treat the cavity after surgery. Radiation therapy is usually performed one to four weeks after a lumpectomy. The temporary devices for example MammoSite or Savi applicator is placed in the cavity by the breast surgeon. The device stays there throughout the treatment, usually 5 days. During your approximately 10 minutes of treatment, the radiation is delivered into the applicators through a wire or cable inserted into a catheter and then removed between treatments. The radiation is delivered based on your treatment plan that is created by your radiation oncologist and the physicist. Treatment plan is usually two treatments per day, 5-6 hours apart, for five days. After the final treatment, the MammoSite or the Savi device is easily removed by the radiation oncologist.
