I had Davinci surgery in April of 07, pre-surgery psa 4.57. I had first post operative psa test in early June with a reading of .62, I had a second a couple of weeks later reading .59. I had a positive margin, a seminal vesicle involved plus a gleason score of 4+5=9. My doctors immediately put me on hormone therapy and then as soon as continency allowed scheduled me for IMRT therapy. I was told that any psa reading post surgery over .2 was indicative of cancer cells still being present.....If I were you I would first get a recheck of the psa and if the readings are still the same ask the Docs about ADT (hormone therapy) and also Radiation therapy.....I'm no Doc but if the psa is correct you need further treatment. FYI.....my psa level is now .05 which is as low as my labs equipment will check....they called that undectable. Good luck in your journey with pca. jwb.
