There has been a lot of controversy in the medical community about the value of performing a radical prostatectomy on a man who already has metastatic disease. Most surgeons wouldn't do it in the past but a number of studies reported that it helped.
Here's an abstract of a new study on the other side that reports that de-bulking does NOT help in the hoped for way:
This seems typical of a lot of the issues in cancer treatment. There's is evidence on both sides of an issue. You can find a specialist who will argue for one side, another who will argue for the other side, and a third who will say, "I don't know, what would you like to do?"
And of course the same is true for patients. You can find plenty of patients who will argue vociferously for or against many treatments.
It all gives me more appreciation of the guys who said, "Make your choice, but whatever you do, don't beat yourself up if it didn't work out. There is no way to know whether a different choice would have worked better and no way to go back and change your mind. Just look to the future and move on."
