Is there any documentation or study, or feedback, indicating Dupytren's getting worse (more nodules, more cords, or more pain, etc), and/or it getting more active, etc, after undergoing R/T Treatments using the German Protocal (5days of radiation--3grays each day, wait a few weeks, then 5days of rays again)

or, is it completely safe in this regard? I.E. It might help, it might not help, but it will categorically not make it worse!

The long-term clinical trials in Germany show that indeed some patients do experience progression after RT, but they are fewer in number compared to the patients that experienced progression in the control groups that did not get RT.

If you're a good candidate for RT, it will improve your odds, but they will still be odds, not certainties.
