This phase II trial investigates how well MRI-guided stereotactic body radiation therapy works in treating patients with early-stage kidney cancer. Radiation therapy uses high energy radiation to kill tumor cells and shrink tumors. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. This method of radiation delivery is further refined through the incorporation of a MRI into the radiation machine to create a device known as a MRI linear accelerator. During treatment with MRI linear accelerator, continuous MRI images are obtained to allow for real-time treatment monitoring and the ability to adjust treatment plans if minor deviations in anatomy are noted. Giving MRI-guided stereotactic body radiation therapy may help treat patients with early-stage kidney cancer.
PRIMARY OBJECTIVE:
I. To evaluate local control following magnetic resonance imaging (MRI)-guided stereotactic body radiation therapy (SBRT) for primary kidney cancer as defined by no growth by imaging at 24 months following SBRT.
SECONDARY OBJECTIVES:
I. To estimate preservation of renal function and to determine frequency of grade 3+ adverse events following SBRT as per Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
II. To characterize tumor and treated kidney changes by multiparametric MRI, including utility of diffusion and perfusion changes in renal cell carcinoma (RCC) prior to and after SBRT as biomarkers of treatment response.
III. To estimate the rate of pathologic complete response as determined by tumor biopsy at 24 months following SBRT.
IV. To estimate rate of no progression by Response Evaluation Criteria in Solid Tumors (RECIST) at 24 months (less than 20% growth in largest tumor dimension as measured by imaging).
V. To estimate the rates of overall survival and distant metastasis. VI. To evaluate economic strain following SBRT for primary kidney cancer. VII. Compare planned total doses to true total doses delivered to the target and adjacent normal structures, to correlate true delivered doses to normal structures to grade 3+ toxicity, and to determine the rate of cases in which the prescribed isodose line failed to cover 100% of the internal gross tumor volume (iGTV).
OUTLINE:
Patients undergo an MRI scan to check the status and location of the disease, including the motion of the tumor during breathing. Two weeks after MRI, patients undergo SBRT over 1-2 hours on 3 non-consecutive weekdays in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 3, 6, 12, 18, and 24 months, then every 6 months thereafter until the end of the study.

| Time to progression | Local control will be defined as no growth (stability or regression) in the largest dimension of the treated tumor by comparison of magnetic resonance imaging (MRI) images at baseline and 24 months following completion of stereotactic body radiation therapy (SBRT). The local control rate will be compared to case-matched data from patients undergoing active surveillance at MD Anderson Cancer Center. In terms of the primary efficacy analysis, the local control will be evaluated along with the 95% confidence interval. For patients who progress earlier than 24 months will be considered as local control failure and will be included in the confidence interval calculation. In addition, we will estimate the probabilities of local control utilizing the Kaplan Meier method with corresponding 95% confidence intervals. | at 24 months |
| Measure | Description | Time Frame |
|---|---|---|
| Preservation of renal function | Patients will undergo split function renal scans to determine glomerular filtration rate (GFR) at baseline, 12 months, and 24 months. Change in GFR will be reported by diving the difference in GFR at baseline and at the respective follow up visit, by baseline GFR. The change of GFR at follow up visits and baseline will be evaluated by paired t-test. Mixed model will be used to explore the change of GFR over time after taking the within-subject correlation. |

|
| Baseline to 24 months |
| Treatment related toxicities | The frequency of non-laboratory non-fatigue adverse events will be determined, defined as a grade 3+ event following SBRT, attributed to SBRT, and affecting the ipsilateral kidney or an adjacent organ (contralateral kidney, liver, small bowel, large bowel, stomach, spleen, or nerves) as per Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. | Up to 24 months after completion of SBRT |
| Changes in the imaging of primary tumor and treated kidney | Patients will undergo MRI of the abdomen at regular intervals (i.e. at 6, 12, 18, and 24 months) permitting analysis of changes in functional imaging biomarkers evaluating tumor and renal perfusion and diffusion, which can be correlated to clinical outcome and toxicities. Mixed model will be used to explore the change of tumor characteristics over time after taking the within-subject correlation. Multi b-value diffusion-weighted imaging (DWI) derived diffusion and perfusion changes will be evaluated over the course of therapy to assess their utility as predictors of renal insufficiency following therapy. | Baseline up to 24 months after completion of SBRT |
| Pathologic response | All tumors will be biopsied at baseline. When safe and feasible, patients will undergo re-biopsy at 24 months following SBRT. Viability and percent necrosis will be determined by hematoxylin and eosin (H&E) staining. Other stains such as ki67 may be included. Taking pathologic evaluation as gold standard for no viable tumor cells following SBRT, will correlate tumor biopsy results with local control by imaging. McNemar test will also be used to evaluate the agreement between local control (yes versus [vs] no) and pathologic evaluation (responder vs none). Will also calculate sensitivity and specificity of our primary endpoint of local control (no growth by computed tomography [CT] scan at 24 months). | At 24 months |
| Progression free survival | Will estimate no progression Response Evaluation Criteria in Solid Tumors (RECIST) at 24 months (less than 20% growth in largest tumor dimension) along with the 95% confidence interval (CI). | At 24 months |
| Distant metastasis-free survival | Will estimate the probabilities of patients remaining free from distant metastases utilizing the Kaplan Meier method with corresponding 95% CIs. The log rank test will be used to compare the survival difference between important subgroups (such as tumor categories, etc.). Cox model will be conducted to examine the clinical factor effect on time-to-event variables. | Up to 24 months |
| Overall survival | Will estimate the probabilities of patient survival utilizing the Kaplan Meier method with corresponding 95% CIs. The log rank test will be used to compare the survival difference between important subgroups (such as tumor categories, etc.). Cox model will be conducted to examine the clinical factor effect on time-to-event variables. | Up to 24 months |
| Economic strain of MRI-guided SBRT | Assessed using the validated ENRICH questionnaire. Questionnaire scores will be calculated based on standardized manual associated with the instrument. Incomplete surveys (in the event that a participant declines to answer one or more questions) will still be considered valid and will be used for study purposes. Descriptive statistics will be used to summarize scores of the questionnaire. The distribution of each continuous variable will be summarized by its mean, standard deviation, median, and range. The distribution of each categorical variable will be summarized in terms of its frequencies and percentages. We will compare results at each time point to estimate financial toxicity of treatment. The association between patient clinical factor (such as T-stage or histology result) and clinical measurement (e.g., local control, pathologic response, tumor characteristics by MRI) will be examined by Wilcoxon's rank sum test or Fisher's exact test, as appropriate. | Baseline to 24 months |
| Planned doses | Will compare planned doses to true total doses delivered to the target and adjacent normal structures. | up to 1 month |
| Correlation of normal tissue true delivered doses with grade 3+ toxicity | Will generate target structure and normal tissue dose volume histograms (DVHs) based on the simulation imaging as per routine treatment planning. Verification MR images will then be obtained immediately prior to each delivered fraction, which may or may not prompt an adaptive plan change. Will use the verification MR images and the delivered plan to generate additional target structure and normal tissue DVHs that will approximate "true" delivered dose. Will generate a cumulative true DVH based on each individual fraction, and compare this to the original planning DVH. Normal tissue toxicity will be assessed in light of both the planned and the true DVH. To assess the impact of intrafraction target and normal structure movement, MR images may also be obtained at specified time intervals during an individual treatment fraction. | Up to 24 months after completion of SBRT |
| Rate of cases in which the prescribed isodose line failed to cover 100% of the internal gross tumor volume (iGTV) | The frequency of non-laboratory non-fatigue adverse events will be determined per CTCAE version 5.0. These events will be correlated to the true delivered dose received by the associated organ(s). The number of cases in which the prescribed isodose line failed to cover the entirety of the iGTV will be determined, and correlated to outcomes. | Up to 24 months after completion of SBRT |
