I am having a Prostascint Scan on Monday. I was injected with the
radioactive agent last Thursday.
Has anyone had the scan and how accurate is it in locating problem cancer
areas?

Past info includes Cryo surgery in 2004, radical in 2005. Severe stricture
problems for past 2 years.
My biopsy of prostate after radical showed a Gleason change from 4-3=7 to a
4-4=8.
PSA has gone from 0.7 to 1.7 within past two months.
I have been told that a bladder augmentation is needed in the future.

Any information would be appreciated on those who have had this type of
scan, results of scan and any who have had a bladder augmentation.

I have been going through many high's and low's during the past two years.
Information from this newsgroup has been very helpful.
Thanks,  Frank

I am afraid it's not all that good finding cancer below 2.0.

However, it doesn't hurt.

And, if you can get them to tell you the technology behind it; the replaced
isotopes and all, it is damned interesting.

Frank...Are you having it done by Dr. Sodee?  He uses Prostascint +
CT/MRI fusion (he calls it SPECT imaging) and his methodology is more
accurate / sensitive than the general Prostascint test.  One thing to
be aware of is that since the test introduces a monoclonal antibody
into your system, it may affect eligibility for antibody-based vaccine
trials, should this matter...Ron

Frank,

As you have been told here, the Prostascint scan is not very good at finding
small cancers.  The theory is great, it just doesn't work that well.  The
good part of the scan is that false positive is somewhat rare.  By that I
mean that if the scan shows a location of cancer, it is fairly accurate.
The problem is that the scan does not pick up many cancer spots.  I have had
the scan done with a post RRP PSA of 2.5, and it was totally a blank a to
locating cancer.  I am not saying that the test is bad, just limited.
