Purpose: To preliminarily evaluate the feasibility, therapeutic effect and toxicity of stereotactic gamma-ray body radiation therapy (γ-SBRT) for asynchronous bilateral renal cell carcinoma (bRCC).
Materials And Methods: A retrospective analysis was performed on the clinical data of nine patients with asynchronous bRCC who were unable to undergo surgery and received γ-SBRT between February 2002 and May 2012. A total dose of 36-51 Gy was delivered to the 50 % isodose line covering the planning target volume at 3-5 Gy/fraction, whereas a total dose of 60-85 Gy was delivered at 5-7 Gy/fraction to the gross target volume.
