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.

Who can I speak with regarding my treatment?

Why Brachytherapy?

Brachytherapy (derived from the Greek word brachys, meaning near or short) refers to cancer treatment with ionizing radiation delivered via radioactive material placed at a short distance from, or within, the tumor.  By placing the cancer-fighting medical radioisotopes in and/or around the affected organ, the treatment can be customized to the individual, delivering high levels of radiation to the targeted area while limiting dose to the surrounding healthy tissue and or critical structures.

The internal targeting allows doctors to effectively treat the infected area while minimizing damaging nearby tissue, and thereby reducing negative side effects — delivering the ultimate in personalized radiation treatment.  Other radiation treatments that require targeting the tumor from an external source, which exposes healthy tissues and limits how high a dose can be safely delivered.

The ability to deliver high concentrated radiation treatment in a tightly controlled area at the time of surgery really allows us to customize and individualize cancer treatment for our patients. Dr. Adam J. Luginbuhl, MD
