Three dimensional conformal radiotherapy [3-D crt] for non-functioning pituitary tumors

ABSTRACT

Introduction: Although pituitary adenomas are histologically benign, the unrelated neurological and physiological consequences can be devastating. Pituitary adenomas are common lesions and represent 10 to 20% of all primary brain tumors. Non-functioning pituitary adenomas comprise approximately 30% of all pituitary tumors. Modern radiotherapy technique, as three dimensional conformal radiotherapy [3-D CRT], have shown efficacy in all aspects of treatment with better immobilization, imaging, planning and treatment. Improvements aim to reduce normal tissue irradiation whilst preserving dose to the target
