Dynamic stereotactic radiosurgery in the palliative treatment of cerebral metastatic tumors.
From October 1988 to April 1990, 9 patients with metastatic brain disease (11 lesions) underwent stereotactic radiosurgery. All patients but two had recurrent metastatic disease after previous brain irradiation. The patients were treated with a single dose of 20 Gy, delivered to spherical target volumes ranging in diameters from 10 mm to 30 mm and prescribed to the 90% isodose surface. All tumors treated showed a favorable response to the treatment, with 4 patients achieving a complete radiological disappearance of the tumor. The majority of the patients experienced a rapid clinical improvement of their symptoms. No complications attributable to the radiosurgical treatment were seen. Stereotactic radiosurgery appears to be an effective and safe treatment for patients with recurrent metastatic brain disease.
