Yes it has been posted on several occasions but newer members may have missed. I did discuss some of the aspects raised with my oncologist at UCLH, particularly with regard to spread despite low or zero PSA. He said this was fairly rare and would not apply with my type of cancer - Adenocarcinoma - the most common type. However, I do like the thinking and aggressive approach of Dr Kwon. This lecture was in 2014 since when more advanced scans have become available than the C11 Choline he advocates in the lecture.
