Apparently prostate cancer markers are fair game on the exam, including new data:

What do you all know about prostate cancer markers other than PSA for both diagnostic and prognostic use? 😱
Relax. They wont be using any of this. The questions are already written for the tests coming in the next couple of months.

Just know PSA and the phosphatases and your gold!
 
As you know, everything is fair game on the test. But by new markers and new data, I would probably be more concerned about recent data that came out in NEJM about whether or not the PSA works. There's been a lot of studies about the effectiveness and whether it changes survival time.

Most importantly, remember that tumor markers are typically used to track progression or relapse, not for diagnostic purposes.
