Abstract:

“Gamma Knife® radiosurgery” is high-dose conformal radiation therapy used for the treatment of small target lesions in the head. It is a minimally invasive technique of multiple fixed, precisely aimed cobalt beams, and relies upon strict patient immobilization via a pinned stereotactic frame to deliver treatment to a precisely located target within a coordinated mapping system. This technique has been widely validated for the treatment of intra-cranial neoplasms and arteriovenous malformations. In this manuscript, two cases of early diagnosed, locally recurrent (persistent) nasopharyngeal carcinoma, successfully treated by Gamma Knife^®, are described. In one of these, early diagnosis by PET scanning may have improved the chance of cure.
