How effective is brachytherapy for prostate cancer with Cesium-131?
Brachytherapy for prostate cancer is a compelling, out-patient option with excellent outcomes data, and swift resolution of side effects in many cases.
A Decade of Data Shows the Value of Cesium-131 Brachytherapy for Prostate Cancer Treatment
The peer reviewed publication, Long-term Biochemical Outcomes Using Cesium-131 in Prostate Brachytherapy, is drawing attention for its positive report on a study of the ten-year findings on the impact of Cesium-131 internal radiation therapy in treating a series of cancer patients.
The publication reported on a study of a series of 571 patients who were treated with Cesium-131 prostate brachytherapy at the Chicago (IL) Prostate Cancer Center by radiation oncologist Dr. Brian J. Moran. The overall group was composed of 55% low risk, 36% intermediate risk, and 9% high risk localized prostate cancer patients as defined by National Comprehensive Cancer Network guidelines.
The overall ten-year biochemical success rate for the entire group was 96.2%. This was the largest and longest followed series of Cesium-131 treated patients reported to date.
Dr. Moran stated: “This is the largest and longest followed series of Cesium-131 treated patients reported to date. Given the notable biochemical outcomes, we view Cesium-131 as an excellent option for patients with localized prostate cancer, which is particularly noteworthy in light of the large component of intermediate risk patients in this series.”
Know All of Your Treatment Options Including Brachytherapy for Prostate Cancer
With so many options and so many different stages and types of prostate cancer, getting educated on success rates and post-treatment impacts on quality of life is perhaps the most important action newly diagnosed men can take.
In conversations with prostate cancer survivors and the physicians that treat them, we hear again and again how important it is for patients to know about all of their options, including brachytherapy for prostate cancer, if they want to receive effective treatment while maintaining the best quality of life possible.
For my patients, I use Cesium-131 instead of Iodine because most of the effective isotope life is spent in 4-5 wks, compared to the 60-day half-life of Iodine,” he said. “Iodine will still be putting out a pretty good dose of radiation 8 or 9 months later. My patients have a shorter duration of acute uropathic complaints because of that.

Our Patient’s Stories
More than 13,000 men have been treated with Cesium-131 brachytherapy for prostate cancer. Here are the stories of three of them.
Brachytherapy Effectively Treats Prostate Cancer
Prostate brachytherapy with Cesium-131 places cancer-fighting medical radioisotopes in and/or around the prostate, as close to the cancer as possible. The isotopes are encased in capsules the size of a grain of rice and release a personalized radiation dose over a period of days. This allows the effective treatment of the prostate while minimizing side effects and damage to nearby tissue.
A comprehensive review of the literature comparing risk stratified patients by treatment with long-term follow-up, Grimm et al, provided a visual comparison of different treatments for prostate cancer.
Quality of life expectations following Cesium-131 brachytherapy for prostate cancer
The short half life of Cesium-131 delivers treatment quickly to the patient, and allows the patient to recover quickly. As seen below, studies have shown that the patient IPSS will return to baseline faster than following brachytherapy with either Iodine and Palladium. This gives patients the opportunity to put treatment behind them, and move beyond their cancer.
