Response from NAACCR:

It looks like TNM Path N, Reg Nodes Ex – Ed 7 (CoC) needs to be updated to allow cN1 and cN2 when regional nodes examined are 00 or 99. Personally, I would leave the edit in the metafile. I think the circumstance you described is pretty rare.

When it does arise, I, I would have the registrar leave the pN data item blank, but calculate the stage as if a cN1 or cN2 is in the data item. This is a valid coding option according to AJCC and all of the other standard setters and it will pass all edits.

At this point we do not plan on releasing a v16f. However, if we do, this edit will be corrected. It will also be correct for pre-2018 cases when we release the v18 metafile.
