Yes, please provide your stats following surgery. There are various nomograms online where you can plug in your numbers and get the probability of a recurrence x number of years after treatment. That being said, I doubt many would recommend taking action immediately unless your pathology was poor. Even if your PSA continues to rise to 0.1 and beyond, it will probably not do so very fast based on your history, giving you time to work on a salvage therapy. If your pathology was good, you may find that your likelihood for a recurrence could be very low.
I have been interested (obsessed?) with the ultrasensitive PSA test since my surgery. Some men are lucky and have a very low number that never fluctuates. Others have to deal with anxiety that goes along with fluctions that may only be noise. Due to my excellent pathology, I have decided to switch urologists and go forward with the "standard" PSA test with a minimum sensitivity of 0.1. This is also the general recommendation from Johns Hopkins. I have had a very small increase from <0.008 to 0.02 over about 18 months, which is probably insignificant, but I still find myself thinking about it. I know some will say that I will lose information about PSA velocity, but I cannot see how this would change my course of action in the event of an eventual recurrence.
Please provide your pathology statistics.
