High-Dose Rate (HDR) Brachytherapy is a form of internal radiation therapy in which radioactive wires or seeds/pellets are placed directly into or near a tumor through catheters, radiating the tumor from the inside out. By delivering a powerful, precisely-focused dose of radiation directly to a tumor, HDR Brachytherapy reduces damage to nearby healthy tissue and decrease side effects of standard radiation therapy.
Because cancer often affects organs that are essential to daily functioning, it is important for radiation treatment to be tightly focused on tumors to avoid serious side effects.
- Before each HDR brachytherapy treatment, we check the position of the catheters with millimeter precision.
During treatment, our doctors insert tiny, hollow catheters directly into tumors to deliver a precise, three-dimensional dose of radiation.
- Next, a series of radioactive pellets are inserted into each catheter. Computer guidance controls how far the pellet goes into the catheter and how long the pellet stays in the catheter to release its radiation dose.
With a few well-placed catheters, HDR brachytherapy can provide a very precise treatment for cancer in just a few minutes
Brachytherapy offers a quicker, more effective way to give radiation treatments for some patients. For many cancer types, the entire Brachytherapy treatment takes 1 to 2 / 5 days, instead of 5 to 7 weeks for external beam radiation therapy (EBRT).
Depending on the type and stage of cancer, Brachytherapy may be combined with other treatments, which can vary treatment times.
In many cases, brachytherapy is a promising alternative to surgical removal of a tumor or the affected organ
Cancers such as cervix, breast, bile duct, esophagus, lung (endobronchial), head and neck, sarcomas can be treated.
