It's been a long time, but I'll take a stab at it.  I belive you have a 55%
chance that your cancer is organ confined, 40% that there is capsular
penetration, and only 2% chance of seminal vesicle involvement or 3% chance
of lymph node invovlement.  The latter two are the next to worse case
scenarios.  At one time, withing the last decade, lymph node or seminal
vesicle invovlement were considered a death sentence.

In other words, "statistically", you should come out of this very curable.
In reality, statistics only mean something when dealing with the whole, but
you should feel pretty good about your chances.

hi sandy - with the low psa and the gleason of 6,  those facts sound
pretty good.  and the fact that you are T2c is because they can feel the
tumor or tumors in the prostate from the DRE.  

the only way you would know for sure if you had negative or positive
margins would be to have the RP.  

radiation would leave everything in place and your psa would drop.

as we say here, it's a crap shoot at best.

knowledge is power - growing old is mandatory - growing wise is optional

Steve Kramer pretty much covered it.   But let me add a bit more
information which may help you understand it.   Partin and his
colleagues examined a lot of prostates which were removed by radical
prostatectomy.   They then compared the presurgical diagnosis, based on
PSA, digital rectal exam (for stage such as T2c), and Gleason score from
the biopsy, with what the post surgical pathology report showed.   The
tables give estimates based on these observations of the PROBABILITY of
certain post surgical pathology results.  These numbers only give you
some idea of how likely something is but don't provide certainty.  Also,
the numbers themselves are subject to some statistical uncertainty.
That is why the tables give both a single number and a range for each
possibility.  The single number is the best estimate, and the true value
is almost certainly within the range.   But just look at the single
number and don't worry about the range.  That is for other scientists
and doesn't really give you anything more to go on.

As Steve pointed out, the categories are: 1> contained with the
prostate, 2> penetrating the prostate capsule, but not in the seminal
vesicles or lymph nodes, 3> found in the seminal vesicles, but not in
the lymph nodes, 4> found in the lymph nodes.   However, keep in mind
that even cancers which have penetrated the capsule are considered
curable.  If the likelihood of 3> + 4> is high enough, most surgeons
will rule out surgery, but that is not true in your case.

Of course, if you do have a radical prostatectomy, you will also have
the results of the post-surgical pathology report, and they provide more
detailed information, on which to base a prognosis.   So except for the
 PSA, the other presurgical data and the Partin tables become moot.  If
you are treated with radiation, that information is not available, so
prognosis is based on the pre-treatment data and whether the PSA drops
to a sufficiently low level and stays there.

As the others have noted, your cancer would be considered highly curable.

There is another twist which might confuse you.  There are two different
ways of listing stages.   The Partin tables include stages 2a, 2b, and
2c, but a newer system combines 2b and 2c as a single stage 2b.  You
have to know which system the pathologist is using, but if you have a
T2c, he is using the same system the Partin tables use.

Good luck.
