Dose Escalation for Larger Brain Metastases: Phase I/II Study
PRIMARY OBJECTIVES:
I. To determine the incidence of acute and long-term toxicities with increasing dose of
stereotactic radiosurgery (SRS). (Phase I) II. To determine if local control may be improved
with increasing doses of SRS. (Phase II)
SECONDARY OBJECTIVES:
I. To determine the risk of acute and long-term toxicity with increasing dose of SRS. (Phase
II) II. To determine if there is increased neurocognitive toxicity with increased dose of
SRS.
III. To determine the rate of radiation necrosis/steroid dependency. IV. To determine if
quality of life is affected more by tumor recurrence versus radiation necrosis. This
includes assessment of progression free survival, overall survival, local failure, and
number of patients who receive bevacizumab, laser interstitial thermal therapy, or surgery
for presumed radiation necrosis.
OUTLINE: This is a phase I dose-escalation study followed by a phase II study.
Patients undergo SRS guided by computer tomography (CT) and magnetic resonance imaging
(MRI).
After completion of treatment, patients are followed up at 1-2, 3, 6, 9, and 12 months,
every 3 months for 2 years, and then every 4 months thereafter.
