Too tempting to answer since you have got not replies so far. I guess, it is still early at your side of the Atlantic. Consider that I am not an expert and my answer is purely based in googling. As other say, essentially I do not know what I am talking about.
T3a means that they detected cancer outside what are considered to be the limits of the prostate, negative margins means that there is not cancer in the limits of what the surgeon has removed so that probably he has taken it all out. There are contradictory statistics but, in average, positive margins or T3a show similar prognosis. It means that you are classified as high risk (or borderline) from the surgery features though, again, you will find different definitions. T3a is definitely better than T3b according to all opinions.
Perineural invasion is another feature that increases risk, but it is not generally a statistically independent predictor. It means that it probably does not add much to your T3a status.
With respect to your PSA increase, you need some more tests to be sure if it means something or not. Good ultrasensitive tests gives usually three digits after the point; therefore maybe your test has an intermediate precission between "normal <0.1" and uPSA and your rising is simply be a fluctuation. You could ask your surgeon about the usual fluctuation observed in other patients taking the same test. Or just ask directly to some of them if you can.
We are not in the same ship, but in similar ones. I do not have any worrying surgical outcome but I have a higher pathological Gleason grade. And I am also getting ambiguous two digit PSA test results.
