Prostate cancer-related abbreviations: What acronym would you add?

There are so many acronyms related to prostate cancer. When newly diagnosed these can be overwhelming and frustrating. As you become more familiar with the diagnosis, consult with the medical team, read reports, BAM! you start throwing around the acronyms like the best of them.

To help newbies, several of you suggested creating a glossary. Let's get it started. Here are the abbreviations most commonly used in the group:

When you use or see an abbreviation in a discussion, please spell it out for others who may be new. If you don't know, ask.

What abbreviations or acronyms would like like me to add to the list?

An error I made: RCT should be Randomized Controlled Trial, not Randomized Clinical Trial.

I would think Side Effects should be abbreviated as SEs, not Ses.

Thanks, Russ. Corrected.


What about SRT for Salvage Radiation Treatment after a RP to distinguish from EBRT for initial treatment

Good catch, @gkm. I was surprised to see that SRT wasn't included.


Hi Colleen, I didn't see PNI listed for Perineural Invasion.


One that I would like to see more often is Immuno-Oncology Translation Network (IOTN). And you might as well add mCRPC for metastic Castration Resistant Prostate Cancer.


Thanks, @hector13 and @mark47. Added.
