简要总结
This study will assess whether Stereotactic Body Radiation Therapy (SBRT) can provide comparable local control, with similar or improved toxicity rates compared to Radio Frequency Ablation (RFA) when treating small renal cell carcinomas.

研究组 & 干预措施
Randomized SBRT
Patients who meet eligibility criteria (unilateral primary renal cell carcinoma less than 4 cm in greatest diameter) and are randomized to Stereotactic Body Radiation Therapy (SBRT) will receive SBRT delivered in fractions of 20 Gy, approximately every other day, for a total of three treatments. If the target is deemed too close to organs at risk, 5 fractions of up to 10 Gy per fraction will be prescribed.
干预措施: SBRT (Radiation)
Randomized RFA
Patients who meet eligibility criteria (unilateral primary renal cell carcinoma less than 4 cm in greatest diameter) and are randomized to Radiofrequency Ablation (RFA) will receive RFA.
干预措施: RFA (Radiation)
Non-Randomized SBRT
Patients with renal cell carcinoma's greater than or equal to 4 cm in diameter, and up to 8 cm in diameter, may be placed in the non-randomized stereotactic body radiation therapy arm. Patients with tumors not amenable to RFA, those with metastatic disease, and those who elect a noninvasive means of treatment will also be eligible to receive treatment in the non-randomized SBRT cohort.
干预措施: SBRT (Radiation)
结局指标
主要结局
Cumulative Incidence of Grade 2 and Greater Toxicities
时间窗: up to 30 days after the last study treatment
The number of patients reporting grade 2 and greater toxicities (for this trial the Common Terminology Criteria for Adverse Events or CTCAE was used).
Proportion of Patients With Local Control of Disease
时间窗: 12 months
On imaging, local control will be defined as when the treated lesion shows no enhancement.
次要结局
- Difference in Quality of Life (QOL) Scores Between SBRT and RFA Treatment Arms(Pre-study, last day of treatment; 1, 3, 6, 12, 18, 24 and 36 months post treatment)
- Metastasis Free Survival Time(36 months post treatment)
- Overall Survival Time(36 months post treatment)
- Difference in Patient Time Away (Measured in Days) Between SBRT and RFA Treatment Arms(Pre-study, last day of treatment; 1, 3, 6, 12, 18, 24 and 36 months post treatment)
- Difference in Incidence of Treatment Related Pain Between SBRT and RFA Treatment Arms(Pre-study, last day of treatment; 1, 3, 6, 12, 18, 24 and 36 months post treatment)
