Ploidy analysis you would pay extra for in pathology, may reveal if PCa is a variant and thus more aggressive, maybe $300-500 more. Dr. Bostwick and Oppenheimer do this and maybe less than a handful of others. You can still have it done as a review, second opinion on your slides and even after a long time span, the parafin wax seals these samples and they last.
Hope is eternal....my stats considerably worse than you posted, the good news is still around and currently in great shape due to overall treatments taken would be my guess. It is not the totally typical 'ride' taken by the majority patients, so maybe I am stupid as some likely believe, but alive and even playing soft rock music as a duet and enjoying things, far from disabled living. I am at year 8+ right now, which has amazed my sorry posterior to some degree, too. Fired a few docs along the way too. My story is found on yananow.net give me an email and will send you the direct link. Yeah I know it can change anytime, been aware of that all along. So I respond to others like yourself, now. While I still have that luxury.
Dx-2002 bpsa 46.6 total urinary blockage and in emergency room, 12/12 biopsies all PCa 75-95% values, gleason scores found 7,8,9's and in two about equal sets of them like that, ct and bone scan (useless) appear clear (meaningless and profittable for them). Protocols that follow not all typical types.
