Experimental: Dose Escalated 5 Fraction Stereotactic Radiosurgery
Patients will undergo dose escalated five fraction stereotactic radiosurgery for diagnosed brain metastases. Tumors must fall into one of two categories: 2.1-4.0cm diameter or 4.1-6.0 cm diameter. Only single largest tumor will be treated with dose escalation. All other tumors (if present) will be treated with standard of care five fraction stereotactic radiosurgery.
Radiation: - Dose Escalated Five Fraction Stereotactic Radiosurgery
As focal radiation techniques are utilized more frequently in the treatment of brain metastases, there is increasing need to accurately define the appropriate patient and tumor characteristics for focal therapy. Unfortunately, not all patients are good candidates for single fraction stereotactic radiosurgery (SRS) since large tumors and those in unfavorable locations have been associated with unacceptable rates of treatment-related toxicity. Five fraction stereotactic radiation has proven to be a more effective treatment for these patients that aren't good candidates.
