Dr. Oneita Taylor: One of the treatments that we frequently use for prostate cancer is that of High-Dose Rate brachytherapy radiation. That's where a radioactive source, it's called iridium, is placed directly in the cancer in the prostate gland. Patients receive three treatments over one and a half days, and it's really well tolerated. We're able to deliver a much higher dose of radiation right to the cancer in the prostate. Sometimes the brachytherapy is given in conjunction with daily and conventional radiation treatments. Oftentimes, brachytherapy is given as a boost of radiation to the prostate. Shortly thereafter, patients may undergo radiotherapy treatment, utilizing the Calypso® directed radiation treatment for a series of treatments over approximately 20 days.
