Brief Summary
This research is being done to see if a delivery of a single high dose of radiation therapy to a small area of the pituitary gland and pituitary stalk in a highly precise manner may be helpful in reducing intractable pain from bone metastases.

Outcome Measures
Primary Outcomes (1)
Change in Intensity of Bone Pain
To estimate the rate of clinically meaningful decrease in diffuse osseous pain following radiosurgical hypophysectomy at 4 weeks following completion of radiosurgical hypophysectomy. Score range 0-10, higher score worse pain. A 2 point reduction in the worst pain severity score on the Brief Pain Index (ie: question number 3) at 4 weeks following completion of radiosurgical hypophysectomy compared to baseline will be considered as clinically meaningful decrease.
Post treatment day 10
Secondary Outcomes (3)
Participants With Reduction in Opioid Utilization Following Radiosurgical Hypophysectomy
Approximately 28 weeks following completion of radiosurgical hypophysectomy
Participants With Radiation Induced Optic Neuropathy Following Radiosurgical Hypophysectomy
Approximately 28 weeks following completion of radiosurgical hypophysectomy
Participants With Radiation-associated Acute and Long Term Neurologic Toxicity
Approximately 28 weeks following completion of radiosurgical hypophysectomy

Research Treatment Plan for all study enrollees
EXPERIMENTALPatients will be treated to a dose of 150 Gy in a single fraction. All patients will undergo CT simulation with 1 mm slices as well as MRI simulation including at least high resolution 1 mm slice T1 weighted MRI. They will be treated in a supine position using an aquaplast mask system for immobilization.
Interventions
Patients will be treated to a dose of 150 Gy in a single fraction. All patients will undergo CT simulation with 1 mm slices as well as MRI simulation including at least high resolution 1 mm slice T1 weighted MRI. They will be treated in a supine position using an aquaplast mask system for immobilization.
Eligibility Criteria
You may qualify if:
- Cytologic proof of malignancy
- Radiographic evidence of bone metastases
- Intractable pain uncontrolled by opioids, medical management, injections/ablation or surgical intervention that would be difficult to address with conventional radiation therapy or other standard options and is limiting the patient's function and quality of life. Intractable pain will be defined as a visual analogue score of at least 4.
- Definitive radiographic progression of osseous and/or visceral metastases on standard staging scans (CT, MRI, bone scan, PET scan or any other standard of care imaging) performed within the last 3 months in spite of standard oncologic interventions and/or inability to tolerate standard oncologic interventions
- Life expectancy at least 4 weeks
- Age≥ 18 years
- Patients of childbearing potential (male or female) must practice adequate contraception due to possible harmful effects of radiation therapy on an unborn child
- Patient must have the ability to understand and the willingness to sign a written informed consent document
- All patients must be informed of the investigational nature of this study and must be given written informed consent in accordance with institutional and federal guidelines
You may not qualify if:
- Prior brain radiation
- Patients must not have a serious medical or psychiatric illness that would, in the opinion of the treating physician prevent informed consent or completion of protocol treatment
- Isolated localized pain amenable to focal radiation therapy, or pain well controlled by opioids, medical management, injections/ablation or surgical intervention
- Malignancies being managed with curative intent
- Life expectancy \<4 weeks
- The tumor amenable to curative management
