Radiotherapy firm Accuray of Sunnyvale, CA, is touting the results of a study on early-stage prostate cancer patients treated with its CyberKnife radiosurgery system.
The study showed that erectile function was preserved in 81% of patients at a median follow-up of two years. Previous research on erectile function preservation at two years for other commonly used prostate cancer treatments, such as open surgery and conventional radiation therapy, has produced values ranging from 50% to 70%.
The study of 112 patients achieved 97% sustained response at two years, with urinary and rectal side-effect profiles comparable to conventional radiation therapy.
The study was published in Technology in Cancer Research and Treatment.
