Men who undergo CyberKnife treatment become keenly aware of their bodies’ functions-and very aware of any change in their PSA levels.
For most men, the PSA level continues to get lower after CyberKnife treatment, gradually falling even after 5 years. But in some men, about 1 in 5, the PSA abruptly goes up and then back down. This rapid rise and fall in PSA is called “the PSA bounce,” and usually happens about 1 ½ to 2 years after radiation treatment.
Prostate cancer specialists speculate that “the PSA bounce” is an inflammatory response after radiotherapy, but we really don’t know for sure. “The PSA bounce” certainly causes a lot of worry both for the patient as well as their doctor.
But the good news is that those men who go through “the PSA bounce” actually do better and survive longer cancer free. This good news was recently published by Dr. Michael Zelefsky and his co-workers in the September issue of the Journal of the American Society for Radiation Oncology (ASTRO). With this extensive study, prostate cancer patients and their doctors can rest easier if they should see the “PSA bounce”
