CyberKnife® Robotic Radiosurgery System proves more efficient than ordinary radiation therapy due to a more accurate targeting of the prostate and corrections regarding its movement. Common radiation therapy cannot trace the movement of the prostate during treatment, causing healthy surrounding areas to be affected by the radiation.
However, pre-surgery prostate cancer data is not always accurate. Due to limitations in prostate cancer staging diagnostics, the true nature and scope of a man’s tumor is not known until it is visualized during surgery. In these post-surgery tests we learn the exact type of prostate cancer, how extensive it is, as well as the status of the seminal vesicles and lymph nodes. Research shows that prostate cancer tumor staging actually changes in as many as 40% of men after post-surgery lab testing.
Men who choose CyberKnife® radiation will be left with a fluctuating PSA level and non-specific tumor results. After CyberKnife® therapy the tumor can take months or years to disappear, or it may remain in the body permanently with stalled growth. A rigorous follow-up schedule must be maintained to monitor PSA level and tumor status for life. While the hope is that the cancer will not return, the testing and worry can be very draining.
According to CyberKnife® research, 84% of patients chose the treatment method because of their comfort with the expected risks and side effects, but only 59% of men believed the procedure was the most likely to eliminate their prostate cancer.
During robotic prostatectomy surgery, Dr. Samadi uses real-time, first-hand visualization to assess the prostate cancer scope and remove the tumor. This proven, minimally invasive procedure integrates the precision and visualization of robot-assisted surgery with the expertise of Dr. Samadi’s vast surgical background. With appropriate follow-up and post-surgery care, PSA level should drop to an undetectable level after robotic prostatectomy surgery.
Radiation such as CyberKnife® can be an effective secondary measure for men with high-risk, recurring prostate cancer.
Over the short term, radiation therapy for prostate cancer can cause:
Long-term CyberKnife® and prostate cancer radiation side effects may include:
