Brachytherapy Treatments

Brachytherapy, also called internal radiation or seed implants, is the placement of radioactive sources in or just next to a tumor. The radioactive sources may be left in place permanently or only temporarily, depending upon your cancer. To position the sources accurately, special catheters or applicators are used.

There are two main types of brachytherapy: intracavity treatment and interstitial treatment. With intracavity treatment, the radioactive sources are put into a space near where the tumor is located, such as the cervix, the vagina or the windpipe. With interstitial treatment, the radioactive sources are put directly into the tissues, such as the prostate.

Often these procedures require anesthesia and brief hospitalization. Patients with permanent implants may have a few restrictions at first and then can quickly return to their normal activities. Temporary implants are left inside of your body for several hours or days. While the sources are in place, you will stay in a private room. Doctors, nurses and other medical staff will continue to take care of you, but they will need to take special precautions to limit their exposure to radiation.

Devices called high dose rate remote afterloading machines allow radiation oncologists to complete brachytherapy quickly, in about 10 to 20 minutes. Powerful radioactive sources travel through small tubes called catheters to the tumor for the amount of time prescribed by your radiation oncologist. You may be able to go home shortly after the procedure. Depending on the area treated, you may receive several treatments over a number of days or weeks.

Most patients feel little discomfort during brachytherapy. If the radioactive source is held in place with an applicator, you may feel discomfort from the applicator. There are medications that can help this. If you feel weak or queasy from the anesthesia, your radiation oncologist can give you medication to make you feel better.

Weekly Status Checks

During radiation therapy, your radiation oncologist and nurse will see you regularly to follow your progress, evaluate whether you are having any side effects, recommend treatments for those side effects (such as medication or diet changes) and address any concerns you may have. As treatment progresses, your doctor may make changes in the schedule or treatment plan depending on your response or reaction to the therapy.

Your radiation therapy team will meet regularly with the other physicians involved in your care to review your case and to ensure your treatment is proceeding as planned. During this session, all the members of the team discuss your progress as well as any concerns.

Weekly Beam Films

During treatment, your treatment team will routinely use the treatment machines to take special X-rays called port films. Your treatment team routinely reviews these films to be sure that the treatment beams remain precisely aimed at the proper target. These X-rays are not used to evaluate your tumor.

On-Treatment Visits

Your doctor and primary nurse will evaluate you every week during treatment. They will monitor your progress and help you manage any side effects. This is called an ontreatment visit (OTV) and will occur on a specific day of the week. If you would like to see your doctor or nurse on a day other than this scheduled day, please tell your radiation therapist. You will usually have one or more blood tests and X-rays during your course of treatment.

After Your Treatment

At the end of your course of radiation therapy, you will receive post-therapy instructions and a follow-up appointment to see your doctor in one to 12 weeks. Along with periodic X-rays and blood tests, it is important for you to continue with regular exams to monitor closely the results of your treatment.
