I have asked questions before, but to reintroduce: radical prostatectomy 3/31/17. Post surgery pathology report: Gleason score 9, Primary tumor pT3a, margin free of tumor, lymphovascular invasion present pN1 (2 of 16 nodes positive), Distant metastasis Unknown, extraprostatic extension of one lymphatic in the adipose tissue of base of prostate. Post op PSAs: .09 on 6/6 and 0.155 on 9/21. Referred to radiation oncologist. Had 8 weeks radiation therapy ending 3/30/18.
Just got first post radiation PSA of <0.13, which doctor said was “lowest” his test would go. Have you all heard of a PSA test where <.013 is the “lowest” measurement?
Also, I have been on hormone therapy (Bicalutamide/casodex) for the past 6 months. Radiation oncologist said there were no studies for Bicalutamide for less than 2 years. When I told doc that I want to quit the Bicalutamide, he responded that was up to me as a “quality of life” decision. So, as per doctor, Bicalutamide suppresses PSA, would it be logical to quit the Bicalutamide in order to determine if I still have cancer; that is, if cancer cells still present, PSA would go up? If PSA doesn’t go up, then I’m good?
One more question: I am also taking Tamoxifen to counter Bicalutamide breast side effects. If I stop taking Bicalutamide, should I stop Tamoxifen at same time or keep taking for awhile...and, if so, for how long?
Thanks in advance for your enlightened responses.
