Early Malaysian experience on the use of head and neck localizers in the precision radiotherapy of intra and extra cranial sites for first 28 cases.

Precision Radiotherapy at high doses require a fixed, referable target point. The frame system fulfills the required criteria by making the target point relocatable and fixed within a stereotactic space. Since December 2001, we have treated 28 central and peripheral nervous system lesions using either radiosurgery as a single high dose fraction or fractionated 3-dimensional conformal radiotherapy using a lower dose and a multi-leaf collimator. Various pathological lesions either benign or malignant were treated. Eighty six percent of our treated lesions showed growth restraint, preventing them from causing new symptoms with a median follow-up duration of 20.5 months. However, the true benefit from this technique would require a long-term follow-up to document the progress.
