Radiofrequency Ablation in Treating Patients With Bone Metastases (ACRIN-6661)
Metastatic Cancer, Pain, Unspecified Adult Solid Tumor, Protocol Specific
About this trial
This is an interventional treatment trial for Metastatic Cancer focused on measuring bone metastases, pain, unspecified adult solid tumor, protocol specific
Eligibility Criteria
4.1 Inclusion Criteria 4.1.1 Histologically or cytologically documented malignant disease with a bone lesion that has the clinical and/imaging features of metastatic disease. 4.1.2 Persistent intractable pain that results in a return visit to the oncologist. The measurable pain must be above a pain scale of five (scale of 0-10). (Pain during the last week described as "the worst" by the patient on a scale of 0 (no pain) to 10 (pain as bad as patient can imagine)). 4.1.3 The patient's pain must be from a solitary site of metastatic disease in the bone. Each site must be amenable to RFA utilizing a percutaneous CT-guided approach. (RF electrode can be safely placed under CT guidance without harm to normal structures.) 4.1.4 The maximum size of the bone metastasis (study site) must be no greater than 8 cm. 4.1.5 Radiofrequency treatment can be performed within 5 days of baseline evaluations. 4.1.6 All patients must understand and sign a study-specific informed consent. 4.2 Exclusion Criteria 4.2.1 Tumor mass in contact with hollow viscera. 4.2.2 Uncontrolled coagulopathy or bleeding diathesis that cannot be corrected with FFP and platelets prior to procedure. (Platelets must be ≥ 70,000/ul.) 4.2.3 Aspirin and nonsteroidal anti-inflammatory medications, antiplatelet medications, or warfarin must be discontinued prior to the procedure for a time period that is appropriate given the drug half life and the drugs known antiplatelet activity (e.g. aspirin for 7 days and ibuprofen 24 hours). Low molecular weight heparin preparations must be discontinued 24 hours prior to procedure. 4.2.4 Tumor involves a weight-bearing long-bone of the lower extremity. 4.2.5 Site of tumor surgically stabilized with metallic hardware. 4.2.6 Previous (within 30 days immediately prior to RFA or post RFA) or scheduled concurrent systemic treatment of metastases with external beam radiation or radioisotopes. (Chemotherapy will not be allowed within 14 days prior to and within 14 days post RFA procedure). 4.2.7 Patients with primary musculoskeletal malignancies, lymphoma and leukemia will not be RFA treatment candidates. 4.2.8 Spinal metastases that do not have an intact cortex between the mass and the spinal canal and exiting nerve roots. 4.2.8 Patients with a pacemaker.

Arms of the Study
Arm 1
Experimental
RFA as pain therapy
Changes in the severity of pain as measured using using the Memorial Pain Assessment Cards (MPAC) before and after RadioFrequency Ablation (RFA) will be statistically analyzed
