High-Dose-Rate Brachytherapy at the Hospital da Luz

Braquiterapia HDR no Hospital da Luz

May 16, the Oncology Center at Hospital da Luz realized its first procedure of High-Dose-Rate (HDR) Brachytherapy in a prostate tumor. This intervention was managed by a multidisciplinary team consisting of experts in Urology and Radiotherapy.

Brachytherapy is a form of internal radiotherapy, whereby the radiation source is placed inside the tumor, or very close to it. There are several types of brachytherapy, which differ depending on the placement of the radiation source in the treatment area, the rate or intensity of radiation delivered to the tumor, and the duration the radiation is administered.

High-dose-rate brachytherapy refers to a rate of radiation exceeding 12 Gy / h. Its application is more common in tumors of the uterus, esophagus, lung, breast and prostate. Most treatments of HDR brachytherapy can be performed on an outpatient basis.

In tumors of the prostate, HDR brachytherapy involves placing a large dose of radiation in the gland for a few minutes in order to destroy cancer cells. This type of prostate brachytherapy may be given as a single therapy when the tumor is localized and is low risk. It may also be combined with external radiotherapy and hormone therapy in tumors of intermediate risk or high risk.
