A Study For Using Radiosurgery On Limited Metastases

In this research study high dose stereotactic body radiation therapy will be directed at the site of metastasis. This treatment will be given once a day, 5 times a week (Monday through Friday) for one to four weeks depending on the location and size of the disease to be treated. Blood for the cytokine tests will be drawn before your therapy starts, weekly during therapy and at the follow-up visits as stated in the next paragraphs. Two to four tablespoons of blood will be removed each time.

Inclusion criteria

Age ≥ 18 years

KPS ≥ 70

Palliative: Disease most likely to be life limiting, is definable, and treatable to a sterilizing dose according to protocol criteria.

The size of the lesion must be such that it can be safely treated to sterilizing radiation doses according to the rules in the protocol

Previously treated lesions are not eligible unless the prescribed dose can be safely delivered. Previously enrolled patients can be retreated to new lesions if they still meet protocol requirements.

Informed consent must be obtained.

Pregnancy test must be negative for women of child bearing potential.

Out of state patients are eligible, if communication with the referring physicians is expected to be adequate to address the primary aim. The secondary aim (blood cytokines) is optional for out-of-state patients.

Exclusion criteria

Technical inability to achieve required dose based on safe dose constraints required for radiosurgery

Women who are pregnant or nursing..

Failure to meet inclusion requirements

Contraindications to radiation.

Patient should not be eligible for primary disease specific radiosurgical protocols
