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.
Patients undergoing prostate brachytherapy with 131Cs have excellent oncological outcomes at 5 years. Although more years of follow-up are required to assess the true cancer control ability of prostate brachytherapy with 131Cs, these intermediate-term outcomes show that there is no reason at this time to suspect that 131Cs will not provide oncological outcomes at least on par with those of 125I and 103Pd.Ron Benoit, MD
Prostate brachytherapy with Cesium-131 has a growing base of clinical experience. This study, from Benoit (1) followed 485 patients of different risk groups treated with Cesium 131 to measure if the disease progressed. At five years, 96% of men with low risk disease, 92.7 of men with intermediate risk disease and 82.9% of men with high risk disease showed no evidence of disease progression.
Quality of Life
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.
Need for Alternative Treatments
With changing healthcare dynamics, clinicians are continually looking for new alternatives for patients with challenging cancers. Brachytherapy with Cesium-131 can provide that alternative:
- In patients with prior radiation treatment for their prostate cancer, the concentrated energy delivery of Cesium-131 may allow additional radiation to treatment residual disease.
- In patients with low volume, low risk disease, Cesium-131 may provide an alternative as a Targeted treatment option, providing a demonstrated therapeutic option with a limited risk of side-effects.
Overall Benefit of Brachytherapy
Many factors contribute to a treatment’s overall “effectiveness”. In addition to being highly effective in treating different forms of cancer, brachytherapy is a fraction of the total cost to the healthcare system when compared to other popular treatments.
