Detailed Description
This study looks at dose escalation treatment in patients diagnosed with brain metastases. Treatment involve five fraction stereotactic radiotherapy for patients with brain tumors 2.1-4.0 cm in diameter or 4.1-6.0 cm in diameter and dose escalation treatment is delivered only to the single largest tumor while all other tumors are treated with standard of care practices if they are present. A dose escalation schedule is proposed based on the monitoring of CNS toxicity and tumor size of the largest tumor, given it falls into the parameters set on diameter.

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.

Outcome Measures
Primary Outcome Measures
- Maximum tolerated dose of five fraction stereotactic radiotherapy [1-2 years]
To determine the maximum tolerated dose of five fraction stereotactic radiotherapy for patients with either tumors 2.1-4.0 cm in diameter or 4.1-6.0 cm in diameter
Secondary Outcome Measures
- Acute toxicity of five fraction stereotactic radiotherapy using Adverse Event questionnaire [1-2 years]
To assess the acute toxicity of five fraction stereotactic radiotherapy for tumors 2-6 cm in diameter using the RAD 1705 Adverse Events Assessment. This assessment was created within our department and will be used specifically for this study.
- Late toxicity of five fraction stereotactic radiotherapy using Adverse Event questionnaire [1-2 years]
To assess the late toxicity of five fraction stereotactic radiotherapy for tumors 2-6 cm in diameter using the RAD 1705 Adverse Events Assessment. This assessment was created within our department and will be used specifically for this study.
- Rate of local tumor control with five fraction stereotactic radiotherapy using Adverse Event questionnaire [1-2 years]
To determine the rate of local tumor control with five fraction stereotactic radiotherapy for tumors 2-6 cm in diameter using the RAD 1705 Adverse Events Assessment. This assessment was created within our department and will be used specifically for this study.
Other Outcome Measures
- Feasibility of capturing patient reported outcomes electronically using FACT-Br Questionnaire [1-2 years]
To assess the feasibility of capturing patient reported outcomes with the Functional Assessment of Cancer Therapy-Brain Questionnaire (FACT-Br) electronically in the Radiation Oncology clinic
