Brachytherapy has been proved to be an effective method for the purpose of
increasing radiation dose to the tumor and reducing the dose to the surrounding normal
tissue. In head and neck cancer, the rationale of brachytherapy is as follows; Firstly,
early small lesion is radiocurative and the major cause of failure is local recurrence.
Seondly, it can diminish evidently the dose to the normal tissue especially masseteric
muscle and salivary gland. Thirdly, the anatomy of head and neck is suitable to various
technique of brachytherapy. On background of accumulated experience of LDR iridium
brachytherapy of head and neck cancer for the last 15 years, the author reviewed the
history of radioisotope therapy, the characteristics of radionuclides, and some important
things in the method, clinical technique and treatment planning. The author analyzed the
clinical result of 185 cases of head and neck cancer treated in the Korea Cancer Center
Hospital. Finally the future prospect of brachytherapy of head and neck cancer is
discussed.
