Brachytherapy in Uveal Melanoma

Professor Rubens Belfort Neto, MD, PhD, explains why brachytherapy is used in the treatment of uveal melanoma.

Brachytherapy in Uveal Melanoma


Brachytherapy is a form of radiotherapy where a sealed radiation source is placed inside or next to the area requiring treatment. In the case of uveal melanoma (UM), a plaque is sutured from outside the eye, placed directly over the cancer that is inside of the eye.

The gray (symbol: Gy) is a unit of ionizing radiation dose, that is used in brachytherapy. It is defined by the amount of energy that is absorved by a certain amount of mass.

In oncologic treatments, the more resistant the cancer cells and the bigger the tumour, higher gray values are needed for an effective treatment.
