This is a dose escalation study using the CyberKnife radiotherapy device for small surgical or medically untreatable renal tumors. Patients with renal tumors 5cms or less in diameter will be accrued onto this study. The ability of CyberKnife to ablate these renal tumors and maintain renal function with dose escalation will be assessed.

Primary Outcome Measures:
  • To determine the maximum tolerated dose of CyberKnife radiation [ Time Frame: 2 years ]

Secondary Outcome Measures:
  • To evaluate local control, overall survival and late toxicity including preservation of renal function [ Time Frame: 2 years ]

Estimated Enrollment: 15
Study Start Date: March 2006
Estimated Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Phase I dose escalation
Radiation: Stereotactic radiation
Dose escalation three consecutive treatments
Device: CyberKnife Robotic Radiosurgery System

Detailed Description:
The CyberKnife Robotic Radiosurgery System is a unique radiosurgical system capable of treating tumors anywhere in the body noninvasively and with sub-millimeter accuracy. The CyberKnife System delivers radiation using a precise targeting methodology allowing a focal treatment margin around the target, thus limiting the volume of adjacent tissue receiving high doses radiation. This in turn allows the delivery of high doses of radiation to the prostate over a short series of treatments.

Ages Eligible for Study:   18 Years to 95 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Tumor size 5 cm or less
  • Radiographic evidence of malignancy or Histologically verified primary renal malignancy.
  • If the kidney biopsy is inconclusive but the radiologist determines that the tumor based on the CT/MRI is highly suspicious for cancer, you may participate
  • Patients with highly suspicious lesions on CT or MRI
  • One -three gold fiducials placed in or around tumor
  • Contradiction or patient refusal to partial or complete nephrectomy
  • Age 18 or greater
  • KPS score 70 or greater

Exclusion Criteria:

  • Irreversible coagulopathies that preclude fiducial placement
