Can someone translate this? Histology post RARP

So I have just had my 6 week consult with the surgeon to get my histology report and it didn't go quite as well as I had hoped having had my PSA test yesterday at <0.01

I have a copy of the report but it's in French and I am sure some of the medical terms did not translate correctly.

The surgeon was very happy to see the PSA at <0.01 and wants to see me in 6 months time so it can't be anything too urgent. She did mention that I might need RT at some time in the future. The Gleeson was upgraded to a 9 (4+5) and a 5 OMS(2016) whatever that is.

So this is what the translated report says - any idea what it means in real English :)
