Monument Health oncology team launches HDR treatment

May 05, 2021 07:58PM ● By Med Editor

Radiation Oncologist Daniel Petereit, M.D., and his team in late April performed South Dakota’s first high-dose-rate (HDR) prostate brachytherapy treatments using real-time, ultrasound-based planning.

The Monument Health Cancer Care Institute is currently the only site in South Dakota that offers this type of comprehensive prostate brachytherapy, both HDR and low-dose-rate (LDR) for men with various stages of prostate cancer. 

Dr. Petereit and his team previously performed more than 200 HDR prostate implants 15 years ago. After recent advances in technology, the team switched back to this method. The technology allows patients to undergo one outpatient treatment, rather than three to four treatments that previously involved a hospital admission for one to two nights.  

The current approach is used for patients with curable, but more advanced prostate cancer.  Patients undergo four to five weeks of daily radiation and an HDR implant. This is also used as a treatment for patients who recur after external beam radiation. 

HDR therapy is a treatment for prostate cancer that involves placing radioactive sources in the prostate gland and delivering a high dose of radiation in a few minutes before the sources are removed on an outpatient basis.
