Francij, I was surprised when my oncologist said a couple of weeks ago the salvage RT was still given as an educated guess. About 6 weeks ago the consultant radiologist said they had lowered the criteria for PSA prior to PSMA scans from 0.5 to 0.3 at our hospital.
Prior to my SRT at 0.2 I asked if the SRT could be delayed to sort stricture out, my urologist said he would be criticised for delaying salvage RT beyond a PSA of 0.4, I started at 0.27.
I don't know how long it takes a lymph node tumor to grow but mine is about 8mm, if that is the only source of the my 1.6 PSA could it have possibly been pick up before SRT five years ago. Presumably something was in the bed because my PSA did drop after SRT.
Thanks Chris
