No change in PSA after rdiation - why?
by RMMJ, Jun 03, 2006 12:00AM
My dad recently finished 7 weeks of radiation, after having his prostate removed. A Prostascan found a few cells in the fatty tissue under the prostate after it had been removed. He went for a follow-up PSA last week and it was 0.5, the same level as before the radiation. What could this mean? The doctor wants to re-do the PSA in three months.

After a radical prostatectomy, the PSA should fall to undetectable levels. Presence of PSA theoretically means prostate, and possibly diseased, tissue remains.
If radiation therapy alone was done, a low-level PSA can fluctuate after treatement.
I would discuss this question with your father's urologist. Repeating the PSA is a reasonable thing to do.
Followup with your personal physician is essential.
