In February my PSA was 18.2. In March/April I had 5 doses of SABR and my PSA has now dropped to 10.4. I had, of course, hoped/imagined it would fall to o and was initially very alarmed but I THINK that such a drop a month after finishing SABR (without ADT) is actually quite positive? Am I right?

  • Hello  

    SABR is like any other form of radiotherapy and works over time. Your lowest or nadir reading should be about 18 months after finishing the course.

    Personally I would have hoped for a bigger initial drop. I assume you will tested every 3 months to keep an eye on it.

    I wish you well with the future results.

    Best wishes - Brian.

  • Thanks Brian. I will talk to my oncologist next week. However, I have been told that a drop of over 40% after a month is pretty encouraging (I'm holding on to this hope!)

  • Hello  

    That sounds fine in that case - I do hope you get a significant drop in the next few months, please do keep us up to speed.

    Best wishes - Brian.
