Cs-131 is a favorable isotope for use across a wide range of tumors and its dose distribution properties facilitate easy calculation and use in the clinic.
Is brachytherapy only for prostate cancer treatment?
No. While brachytherapy has been used extensively over time to treat prostate cancer, its application goes beyond prostate to other treatment areas. We are seeing particularly exciting applications in head/neck, brain, as well as other treatment areas.
What is brachytherapy?
With brachytherapy (or seed therapy), cancer-fighting medical radioisotopes are implanted in and/or around the affected tissue, as close to the cancer as possible. The isotopes are encased in capsules the size of a grain of rice and release a radiation dose, tailored to each patient, over a period of days. This allows doctors to effectively treat the infected area without damaging nearby tissue, and thereby reducing negative side effects. Learn more about brachytherapy here.
How effective is brachytherapy relative to other treatment types?
Brachytherapy has been found to be just as effective as other forms of treatment but has the benefit of shorter treatment times as well as having less side effects. Learn more about brachytherapy here.
What are the advantages of Cesium-131 by Isoray over other isotopes?
Cesium-131 by Isoray has a higher average energy as well as a shorter half life than other commonly-used radioisotopes (I-125, Pd-103). Benefits of these unique attributes are a reduction in some common prostate side effects (such as urinary or sexual performance side effects), greater coverage of the infected organ, and a reduction of the total radiation treatment time. Learn more about the benefits of Cesium-131 by Isoray here.
