About
This pilot clinical trial studies cryosurgery and radiation therapy in treating patients with painful bone metastases. Cryosurgery kills tumor cells by freezing them. Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells and shrink tumors. Giving cryosurgery together with radiation therapy may kill more tumor cells
Full description
PRIMARY OBJECTIVES:
I. To assess the potential for efficacy and safety of combining percutaneous computed tomography (CT)-guided cryoablation and radiotherapy for the palliation of osseous metastases.
OUTLINE:
Patients undergo cryosurgery. Beginning 2 weeks later, patients undergo 1, 10, or 15 fractions of radiation therapy 5 days per week for 1-3 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 24 hours and weeks 1-2, 4, 12, 18, and 24.

Inclusion criteria
Pathologically (histologically or cytologically) confirmed metastatic disease with a new tumor involving or abutting bone that has the clinical and imaging features of metastatic disease
Current analgesic therapies have failed (worst pain of 4 or above as measured by Brief Pain Inventory [BPI], despite analgesic therapy) OR the subject is experiencing intolerable side effects that preclude analgesic use (resulting in pain of 4 or above, as measured by BPI)
Pain must be from one or two painful metastatic sites in the bone (additional less painful metastatic sites may be present)
If the index tumor is in the spine, there must be an intact cortex between the mass and the spinal canal and exiting nerve roots
Patients must have stable use of hormonal therapy for two weeks prior to study registration and two weeks prior to cryoablation procedure)
Stable use of pain medications (no changes within two weeks of cryoablation procedure)
Eastern Cooperative Oncology Group (ECOG) performance status 0-2
Life expectancy >= 2 months
Platelets > 50,000/mm^3
International normalized ratio (INR) >= 1.5
Patients may not have any debilitating medical or psychiatric illness that would preclude giving informed consent or receiving optimal treatment and follow-up
Patients who are taking antiplatelet or anticoagulation medication (e.g., aspirin, ibuprofen, low molecular weight heparin [LMWH] preparations) must be able to discontinue such treatment prior to the cryoablation procedure for an appropriate amount of time; at least 5 days should be allowed after discontinuation of aspirin, Coumadin, clopidogrel, and dipyridamole; at least 12 hours should be allowed after discontinuation of LMWH preparations
Patients must be clinically suitable for cryoablation therapy
Patients must be clinically suitable for radiation therapy
Patients must be able to understand and willing to sign a written informed consent document
