Same with me David -- I had one clinicaly involved node, , between 2 and 3 cm as I recall,and one more that was microscopically involved.
I was under the impression that having more than one node was automatically staged IV, with size coming into play as well.
Don't get me wrong -- if you want to call me Stage III instead of IV, I ain't going to complain! ;-)
Seriously, I would be interested in seeing more on this.
