Brief Summary
The specific aims of this study are:
- 1.To determine the safety and feasibility of treating patients with a combination of MRI guided stereotactic body radiation therapy and microwave ablation.
- 2.To assess short and long-term toxicity rates of patients treated with a combined modality approach.
- 3.To assess local control, survival, and pathologic response to treatment

Outcome Measures
Primary Outcomes (1)
Dose-limiting Toxicity With SBRT Combined With Microwave Ablation for Renal Cell Carcinoma
Dose-limiting toxicity (DLT) will be defined as grade 4 or higher non-hematologic toxicity attributable to treatment. This will exclude toxicities not caused by treatment, such as pain due to tumor progression. Toxicities will be defined per NCI CTCAE v5.0.
Until 30 days after ablation (up to 12 weeks on study)
Secondary Outcomes (4)
Local Control Rate Per RECIST Criteria as Reported by Count of Participants
8 weeks
Progression Free Survival
8 weeks
Overall Survival
8 weeks
Tumor Pathology of Post-SBRT Specimen (H&E Staining)

Study Arms (1)
Radiotherapy & Microwave Ablation
EXPERIMENTAL3+3 dose-escalation wherein three dose levels of stereotactic body radiation therapy (SBRT) would be evaluated: 1. Dose level I: 6 Gy x 5 fractions 2. Dose level II: 8 Gy x 5 fractions 3. Dose level III: 10 Gy x 5 fractions Radiation treatments will be delivered two to three times a week, with five fractions completed over two weeks. Four to six weeks after radiation treatment, patients will undergo repeat CT or MRI imaging to assess tumor response and suitability for microwave ablations. Eight weeks after the conclusion of SBRT, patients will undergo microwave ablation (approximately 12 weeks after registration).
Interventions
Patients will be treated on study with a course of SBRT treatment by a radiation oncologist. Three SBRT dose levels targeting the primary tumor will be evaluated; level I: 6 Gy x 5 fractions (a common palliative dose), level II: 8 Gy x 5 fractions, and level III: 10 Gy x 5 fractions (a common definitive dose).
Performed under sedation using ultrasound and computed tomography (CT) guidance for percutaneous antenna placement and confirmation. Depending on size and location of tumor, one to three antennas (Certus 140; NeuWave Medical) will be used. The system is an FDA-approved, high-powered third-generation MW device that uses CO2 gas cooling to prevent shaft heating. The gas cooling allows the probes to be stuck into tissue by creating a small ice ball at the tip using the Joule-Thomson method, similar to the tissue cooling mechanism of cryoablation systems. Probes are 17-gauge, and various ablation zone configurations are available depending on the probe selected. An ablation protocol using the 65W power setting for 5 minutes will be used for most patients. Ultrasound will be used for real-time monitoring of the extent of ablation to achieve a 5mm margin beyond tumor, and immediate post-procedure imaging performed using contrast-enhanced CT (CECT) for patients with adequate renal functions.
