Hi. Following up on a post from a while back.

I had an RP in August last year and it appears I'm experiencing BCR.

T3b disease, Gleason 4+5 on pathology. Biopsy suggested 3+4. 6mm +ve margin. Pre op PSA 6.8 No nodes or disease elsewhere on pre op PSMA Pet scan.

First PSA was 0.03, then down to 0.01. Up ten fold to 0 1, now 0.4 six weeks after the previous 0.1. 

I've had a conversation with my surgeon who suspects lymph node could be the culprit and I'm having a PSMA next week.

I'm guessing RT + HT for maybe 6, 12, 18 months?

Has anyone been here with experience to share please?

Given your pre-op PSMA scan didn't show lymph node involvement and you had a positive margin, it seems much more likely that the PSA is coming from the cancer left behind by the surgeon, than cancer cells which were already elsewhere in your body.  Next PSMA scan will hopefully establish the truth of that.

If the only cancer cells are those in the prostate bed, salvage RT has a high chance of killing them. Quite often SRT is given without HT, your oncologist will be the person to decide what happens next.

There was someone on here recently with a very fast climb, so fast that it's thought to be a false result needing a retest.     0.03,  0.01, 0.1, 0.4 is a fast climb in 8months, and 4x in 6 weeks is as well.   Your pre-op level at 6.8 isn't particularly high.  For a bit left behind to be growing that fast seems unusual.  Knowing the dates might make it clearer, I think I'd be suspicious of the 0.01 and the 0.4.  The first because it's a very sensitive test if it's 0.01 or even <0.01. The 0.4 because it's a fast rise in the short time.  I've had some ups and downs in my tests, you never find out why it's always looking to the next one and what it might be and what you might do.  Good luck,  Peter

Thanks Dave.

Yes, I was surprised he didn't suspect the area at the margin Dave. I guess we'll soon find out. He did say these are still tiny numbers, and the rate of rise didn't seem to spook him.

Thanks Peter. Yes, it did surprise me. The surgeon pointed straight to a lymph node in the conversation I had, rather than the prostate bed. I guess the PSMA which is coming up very soon will tell us.

O.03 was a few weeks post op

0.01 three months later

0.1 three months after that, the 0.4 at 6 weeks later.

Our hospital has a super sensitive machine apparently.

Just to add, after an afternoon of research(!)

Short doubling times do indeed indicate lymph node metastasis rather than local recurrence. Just hope it's one or two that can be treated fairly routinely.
