RF Ablation of Treatment of Metastatic Lesions in Patients Undergoing Antiangiogenic Therapy for Stage IV Renal Cell Carcinoma
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.

|Official Title:||Pilot Feasibility Protocol of RF Ablation of Treatment of Metastatic Lesions in Patients Undergoing Antiangiogenic Therapy for Stage IV Renal Cell Carcinoma|
- To evaluate the safety, toxicity and feasibility of RFA for the treatment of metastatic lesion in patients undergoing antiangiogenic therapy. [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
- To evaluate the efficacy of RF ablation by measurement of diameter of ablation for treatment in this patient population. [ Time Frame: 3 years ] [ Designated as safety issue: No ]
- To evaluate relative efficacy of RFA in treatment of metastatic lesions showing sensitivity vs. resistance to anti-angiogenic therapy. [ Time Frame: 3 years ] [ Designated as safety issue: No ]
- To examine the mechanism of resistance to antiangiogenic therapy by examining the pathologic findings in sensitive and resistant metastatic lesions in patients with RCC treated with sorafenib and sunitinib. [ Time Frame: 3 years ] [ Designated as safety issue: No ]
- To study the relationship of peripheral blood angiogenic markers and vascular imaging to molecular changes within the tumor in sensitive and resistant metastatic lesions. [ Time Frame: 3 years ] [ Designated as safety issue: No ]

Procedure: Radiofrequency Ablation
- 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.
