The study investigated the effectiveness of CyberKnife (CK) SBRT in approximating HDR brachytherapy doses for prostate cancer while comparing planning and patient outcomes.
In a trial involving ten patients, CK SBRT showed similar planning target volume coverage to HDR, but with lower urethra radiation doses in most cases, indicating a potential for reduced toxicity.
Four months post-treatment, patients exhibited a significant reduction in prostate-specific antigen levels, with manageable acute side effects mostly resolving within two months.
