I am a 73 year old man who had a diagnosis of prostate cancer in April, 2012 (Gleason score 7, one positive of 12 biopsies). I had radical prostatectomy, and the pathology report indicated the cancer was confined to the prostate with no evidence of any spreading. The path report did say that there was "perineural" involvement. Four months after the surgery, I had a PSA done at a commercial laboratory with a result of 0.2. The surgeon said it should have been undetectable and ordered the test repeated at his hospital lab. This result returned at 0.34. The conclusion was that I should have radiation to the prostate bed. I had IMRT starting in July, 2013, and the 3 month post radiation PSA done at the same commercial lab that gave the initial result was again 0.2. The radiation oncologist was pleased that the result dropped from the 0.34 result obtained in January, 2013. I was hoping for an undetectable result. I had wanted the radiation oncologist to order a baseline PSA prior to the radiation treatments, but he said it wasn,t necessary. My concern is that the 0.2 and 0.34 results were from different labs. I had read that the same lab should be used to follow PSA changes. Does anyone have any thoughs on this?
