The trend formula on my Excel spreadsheet predicted that my PSA would come in at 0.69 ng/mL, and my PSA came in at exactly 0.69 ng/mL. Not too shabby.

To be honest, that’s a little better than I expected it to be, which I’m not complaining about. At least it hasn’t taken off like a Halloween bat out of Hell.

The one question that we’ll have to answer at the appointment with the urologist on 14 November is whether that level is high enough to warrant another PSMA PET scan to see if we can detect any hotspots that may be amenable to radiation. At my current PSA level, there’s about a 70% chance of detecting anything, but if we wait until the PSA is closer to 1.0 ng/mL, there’s a 90% chance of detection. Maybe we wait another three months and go from there? Or, maybe we go ahead with the scan now and I have cool images to include with my Christmas cards.

I’m guessing that that was a small enough increase—keeping my PSA at a low level—that we won’t have to worry about starting androgen deprivation therapy (ADT) quite yet. Of course, I could be wrong.

When I use my last five PSA tests over the last year to calculate PSA doubling time, the PSADT is 7.7 months.

Stay tuned.
