Evaluate congratulations you are awarded post # 200,000 on NWBO ihub boards. May a new chapter,for the better, begin for longs,patients,researchers,and management.
I am just a rube, Evaluate, but I think it means that there were 12 or so that originally were thought to have progressed, but have survived longer (maybe till now), so it was just pseudoprogression and not actual progression... which means more have not progressed... :)
