Remote High Dose Rate Afterloading Brachytherapy

What is Remote High Dose Rate Afterloading Brachytherapy?

Brachytherapy is a form of radiotherapy, by which a radioactive source is placed into body or cavity through hollow tubes or needles (called applicators) to get to the inside or close to the tumour itself. After 5 to 20 minutes of treatment, the source travels back along the applicators to the brachytherapy machine and patient is no longer radioactive. This procedure delivers a high dose of radiation to the target with only a minimal dose affecting the surrounding tissues.

On what conditions can the treatment be performed?

This treatment may be done along with external beam therapy to help destroy tumour cells for certain types of cancer. It is often used in the treatment of oesophagus, cervix, uterus, vagina, sarcoma, and head and neck cancers.
