I believe they punched my biopsy 3+4 numbers into a nomogram and used the result to decide if lymph nodes should be removed. I was very confident in my doctor and trusted his judgement. I didn't really ask but believe node removal, for my case, was mostly diagnostic for staging. Thankfully, all 13 were negative. I had confirmed cancer in my prostate and it looked contained from the MRI images. Didn't have a PSMA pet scan. I did do a Prolaris test it indicated that I was on the borderline for treat or active surviellance. Looks like the biopsy missed the bad stuff because
my surgical pathology gleason grade was upgraded to 4+3, tertiery 5, cribriform, PNI. The margins were negative and so were the 13 nodes. I've been < .1 for 22 months. I was never incontinent but it took about 7-8 months for erections with the help of viagra. I hate cialis and viagra but still need it to this day.
