What the experts said
CyberKnife is a newer technology that allows noninvasive treatment of prostate cancer
University Hospitals Case Medical Center is one of the initial institutions offering CyberKnife technology
CyberKnife delivers highly focused radiation directly at the prostate and tracks the movement as the prostate moves
CyberKnife allows very precise treatment of the prostate while minimizing injury or side effects from surrounding organs
CyberKnife treatment does not involve chemotherapy or other treatments and is standalone
Current CyberKnife treatment is for patients with low risk or intermediate risk prostate cancer
CyberKnife candidates have PSA less than 10
CyberKnife candidates have Gleason score of 3+4 or less
Standard external beam radiation can be 5 days a week for 6 to 9 weeks, up to 45 treatments
CyberKnife treats patients in 5 treatments total
Each CyberKnife treatment takes about 1 hour, for 5 hours total treatment time
No prostate cancer treatment has been able to totally remove the possibility of having side effects
CyberKnife patients experience about 2 to 3 weeks of either no side effects, very mild urinary or rectal side effects, or sometimes bothersome rectal or urinary side effects
Most CyberKnife side effects have gone away by 3 to 4 weeks
Urinary incontinence and erectile dysfunction are possible side effects of CyberKnife but have been found to be very minimal in patients at this institution
