I am also a stage IV Melanoma patient and have been participating in a phase II clinical trial for it since March 2010. Part of the trial protocol requires PET/CT or CT scans on a regular basis. The CT scans showed an enlarged prostate and later on, the PET/CT showed hypermetabolic activity with current uptake values ranging from 3.7 – 4.0.
I went and visited a urologist for advice. My PSA came back 1.8, but based on the scans, we decided on a biopsy. It came back with a Gleason 6 (3+3) with only 2 cores involved at 5%. About six months later, I had another biopsy by a different practice and the result was the same.
A consult with a surgeon was uplifting. His opinion was I probably did not have to worry about the prostate given the prognosis for stage IV melanoma. Ha, I’m proving that all wrong.
Anyway, my current PSA is 2.04 and I am still on the path of active surveillance. There are so many different opinions for you to consider, all with very valid points. You have the difficult task of weighing all the information here, from other sources, from your doctor, and making the decision you feel is best.
Good luck to you.
