Brief Summary:
Renal Cell Carcinoma (RCC) is the most common type of kidney cancer. The usual treatment for this type of cancer is surgery. Considering the most common patients are an average age of 65 and some are not suitable candiates for surgery, there is great interest in non-surgical alternatives for kidney cancer treatments. This study will investigate the use of Stereotactic Ablative Radiosurgery (SABR) for renal tumors. SABR is a non-invasive alternative, which involves delivery of high doses of radiation to the target, while minimizing the risk of injury to the surrounding organs. Patients will be seen before and end of treatmetn and will be followed at 4 month intervals for up to 2 years. During the follow ups, patients will be asked to complete a quality of life questionnaire and will have standard of care imaging.

Primary Purpose: Treatment
Official Title: Phase II Study: Stereotactic Ablative Radiotherapy for Renal Tumors
Actual Study Start Date : November 1, 2018
Estimated Primary Completion Date : November 2023
Estimated Study Completion Date : November 2023

Arm Intervention/treatment
Experimental: Stereotactic Ablative Radiotherapy
Adult patients with Kidney mass (either primary or metastasis) amenable to SABR
Radiation: Stereotactic Ablative Radiotherapy
Stereotactic Ablative Radiotherapy to renal tumors with a dose of 27.5-40 Gy in 5 fractions.

Primary Outcome Measures :
  1. To evaluate the radiation induced renal impairments in patients receiving SABR. [ Time Frame: 2 years ]
    The prevalence of nephron toxicity in patients treated with SABR, measured by the change in Glomerular Filtration Rate (GFR) every 4 months over 2 years.

Secondary Outcome Measures :
  1. Chronic Kidney Disease Stage Progression [ Time Frame: 2 years ]
    Chronic kidney disease stage progression after SABR, assessed by the Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines

  2. 2-year Local recurrence rate [ Time Frame: 2 years ]
    2 year local recurrence rate of kidney tumors treated with SABR, measured by assessing the change of irradiated kidney function on functional imaging.

  3. Patient Reported Outcomes [ Time Frame: 2 years ]
    The change in quality of life of patients treated with SABR, assessed through the use of NCCN FKSI-19 questionnaire.

  4. Incidence of acute and late toxicities [ Time Frame: 2 years ]
    The incidence of acute (≤3 months) and late complication of interest (GI or GU complications, high blood pressure and adrenal insufficiency) as assessed by CTCAE version 5.0.
