Kidney Cancer Clinical Trial
RF Ablation of Treatment of Metastatic Lesions in Patients Undergoing Antiangiogenic Therapy for Stage IV Renal Cell Carcinoma
Summary
The purpose of this study is to look at the effects of a procedure called radiofrequency ablation on kidney tumors from patients who are undergoing antiangiogenic treatment. Antiangiogenic treatment is a type of treatment that inhibits formation of new blood vessels that are required for tumor growth. Radiofrequency ablation (RF ablation) involves inserting a needle into tumor tissue and administering heat to the tumor tissue that is sufficient to kill the tumor cells.
Full Description
Participants will undergo a RF ablation procedure of one or more of their tumors that have not gone away while they have been undergoing antiangiogenic treatment. The RF ablation procedure will be performed in the operating room at one of the Dana-Farber/Harvard Cancer Center hospitals and will be performed under general anesthesia.
Blood will also be drawn 2-4 weeks before the procedure, at the time of teh procedure and 2-4 weeks after the procedure.
The RF ablation procedure will be performed at specified times in relation to the participants antiangiogenic treatment (sorafenib or sunitinib): a) If the participant is taking sorafenib, they will be asked to stop taking it 2-5 days prior to the RF ablation procedure; b) if the participant is taking sunitinib, they will be asked to stop taking it 4-7 days prior to the RF ablation procedure.
Participants will have an MRI or a CT scan of their tumor(s) within 2-4 weeks of the procedure and 2-4 weeks after the procedure. The MRI or CT will scan the tumor(s) to determine how much blood flow is going to them.
At the time of RF ablation, participants will have a biopsy of their tumor(s) and will receive a CT scan in the area the ablation was performed after the procedure to assess for any bleeding. They will also be monitored for 4 hours after the RF ablation procedure.
Eligibility Criteria
Inclusion Criteria:
Patients who are on antiangiogenic therapy for a minimum of 4 weeks and have isolated metastatic lesions showing either persistence or resistance to therapy that might benefit from local therapy such as RF ablation.

Patients currently on anticoagulation
Medical contraindication to MR imaging (pacemaker, metal debris in eye, etc.)
Prior RF to the index tumor
