LDR brachytherapy

Also known as: Low-dose-rate brachytherapy, Prostate seed implant, Prostate brachytherapy, 1-125 brachytherapy

LDR involves the longer placement of the temporary or permanent radiation sources into the tumor area, such as a prostate seed implant, with the radiation dose delivered over several days or months. A typical example of LDR is prostate brachytherapy. Several Providence physicians have more than a decade of experience with this type of treatment, which is appropriate for selected patients with low or intermediate risk prostate cancer. The radiation oncologist works with a urologist to place the seeds in the prostate during a short procedure performed in the operating room. The seeds emit a low-energy type of radiation, which is not powerful enough to travel outside the body or affect others. The seeds naturally decay and deliver radiation to the prostate over several months. The seeds eventually emit less radiation over time and do not need to be removed.

Iodine-125 plaque therapy for ocular melanoma

Iodine-125 plaque therapy is a treatment during which an eye specialist, otherwise known as an ophthalmologist, attaches a plaque slightly smaller than a quarter to the back of the eye. The radiation oncologist works closely with the ophthalmologist to customize a plaque containing radioactive iodine seeds that deliver a high dose to the tumor located in the back of the eye, with a small dose delivered to the remainder of the eye. The plaque remains in place for two to three days, and the majority of patients do not experience vision loss. We work with several ophthalmologists to perform this procedure and have more than 10 years of experience using this approach to treat patients with melanoma arising in the eye.
