What do you understand by the term "undetectable"? The American Urological Association continues to define ‘recurrence' post-prostatecomy as a PSA of >0.2ng/mL. I have come to know this is misleading and dangerous. I experienced first hand at the Royal Marsden, London, they begin PSMA PET CT imaging at usPSA 0.03 post RP. I had confirmed lymph node metastases at usPSA of 0.13; this was after RP and RT had failed to clear all my cancer. Some of these mets were pretty high up in the lymph node pathway and would have almost certainly become more distant and untreatable if I had waited until my PSA reached 0.2. They were identified by PSMA PET CT combined with nanoparticle MRI in The Netherlands, and removed via robotic surgery in Belgium.

Imaging and lab tests for detecting recurrence at extremely low PSA levels are becoming more available, and the AUA will surely have to amend their definition of recurrence in the light of these advancements. The testing service I used most recently can report levels below 0.01 (the value I have been using). If your urologist cannot offer you this level of testing, you can access it directly and reasonably priced, in most states, via Request A Test. Today, 20 months post pelvic lymph node surgery, I continue undetectable for remaining prostate cancer; now relying on <0.006.
