 One Day Radiation May Become An Option |
|
|
Doctors in Canada are studying the effectiveness of permanent radiation seed implants following lumpectomy as an alternative to whole or partial breast irradiation for early-stage breast cancer patients, according to a recently published study in the International Journal of Radiation Oncology Biology Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology. This type of radiation would cut treatment time for certain patients from several weeks to one day.
For early stage breast cancer, women often undergo a lumpectomy to remove the tumor followed by radiation therapy to kill any cancer cells that may remain. Most women undergo external beam radiation, which is given every day, Monday through Friday, for six to eight weeks. Doctors have been experimenting with ways to shorten this treatment. One technique used by a growing number of radiation oncologists involves the use of temporary radiation implants. These radiation sources are delivered through a catheter into the breast, usually twice a day for one week.
In this study, the first of its kind in the world, doctors wanted to see if it was possible to use permanent implants, like what many men receive to treat prostate cancer, to combat the cancer with only one treatment. These implants, about the size of a grain of rice, would not be removed daily like with the temporary implants. Rather, the radioactive seeds would deliver radiation to the breast area for a number of weeks until they were no longer radioactive. The advantage over the temporary implants is that the patient only has to undergo one surgical procedure to receive the radiation, versus 10 treatments over one week for temporary implants. |
