All subjects will have cryoablation combined with radiation on one or two painful metastatic bone tumors.

For cryoablation in the palliation of painful bone metastases, subject preparation, anesthesia, intra-operative monitoring, and postoperative management are identical to those of standard cryoablation routinely performed at all clinical centers participating in this study and are at the discretion of the investigator.

Cryoablation

Radiation therapy is usually performed with 6-18 Megavolt photons from a linear accelerator. The proposed dose and frequency of radiation for this protocol are: 8 Gray in 1 fraction, 30 Gray in 10 fractions, or 37.5 Gray in 15 fractions. These proposed doses or other doses will be prescribed at the discretion of the investigator. It is anticipated that subjects will begin the radiation therapy approximately within one to three weeks after the cryoablation procedure. The doses and frequency of the radiation treatment will be collected as well as toxicities.

Radiation

Jerry Matteo, MD

This study will evaluate the safety and efficacy of cryoablation therapy combined with radiation therapy for the relief of pain associated with metastatic bone tumors.

Patients with painful bone metastases who meet the eligibility criteria and who have been determined to be an appropriate candidate for cryoablation therapy and radiation therapy will be offered enrollment into the study. Cryoablation is the process of destroying tissue by the application of extremely cold temperatures. Galil Medical Cryoablation Systems are used as a surgical tool in the fields of general surgery, dermatology (skin), neurology (nerves), chest surgery (including lung), Ears-Nose-Throat (ENT), gynecology, oncology (cancer), proctology (colon/rectal) and urology (kidney). Radiation therapy, also called radiotherapy, uses carefully targeted doses of high-energy radiation to kill cancer cells. Radiation is used to treat many kinds of cancer.

Patients agreeing to participate will read and sign an informed consent form and thus become subjects in the study. Treatment will be performed using a Galil Medical cryoablation system and Galil Medical cryoablation needles. Subjects will be followed for up to 24 weeks (6 months) for palliation of pain, quality of life and analgesic usage. Baseline and follow-up data will be collected for each subject via a web-based electronic data collection tool.

Safety and Efficacy of Cryoablation Combined With Radiation Therapy for the Palliation of Painful Bone Metastases

Cryoablation Combined With Radiation Therapy for the Palliation of Painful Bone Metastases

The endpoint for this study will be measured as follows: assessment of the effectiveness of cryoablation combined with radiation associated with palliation of pain in subjects with metastatic bone cancer by measuring the average difference of pre- and posttreatment worst pain in 24 hours from baseline to 24 hour, 1, 4, 12, and 24 week follow-up intervals as measured on the numeric 0 to 10 Brief Pain Inventory (BPI) scale.

If the first cryoablation procedure effectively relieves pain but the relief wears off over time and the pain becomes unbearable, a second procedure may be performed. The number of repeat cryoablation treatments will be recorded.

If pain is not effectively relieved by the cryoablation, other surgical treatments may be performed. The number of these treatments will be recorded.

The number of subjects (percentage) who are able to reduce analgesic medications from baseline to 24 hours, 1, 4, 12, and 24 weeks after cryoablation will be recorded.

The difference in pain scores will be assessed from baseline to follow-up intervals after cryoablation will be analyzed. The interval indicating the most relief from pain will be compared across subjects.

The safety endpoint for this study is to assess the incidence and severity of intra-operative events, post operative adverse events, serious adverse events and unanticipated adverse device effects related to the cryoablation procedure.

Time to recurrence of worst pain at or above baseline; worst pain score in the 24 week follow-up period as measured on the numeric 0 to 10 BPI scale

Subject satisfaction will be compared at baseline to follow-up intervals.
