Does this mean that all is well, or just that the lymph nodes were not removed, so the pathologist can't tell if there is not metastases?

Means cannot be assessed....thus they don't know...weren't sampled on the nodes and unknown on mets at that time.

From Google:

"We pathologists only can make assessments based on tissue provided us.

The Mx indicates that the pathologist had no tissue to assess whether any distant spread had occurred. It is a subtle distinction. Similarly, if I am not provided any lymph nodes to examine, then the N would be reported as Nx."

If Lymph nodes were provided to the pathologist, they would be listed in the summary of the tissue samples. Not all surgeons take them, and when they do, it seems that the number is all over the place.

As others have said, this means they were not assessed. But it also means the surgeon didn't think it was necessary to take them out, which is a good sign, at least in the case of good surgeons. Can he have made a mistake and left in some positive ones? Sure, in fact I may be a case for that, although I doubt if they would have seen anything even if some had been removed.

The MX made me uncomfortable also until a friend explained that it can't be anything else because the surgery itself cannot produce such a determination.

Surgical skill, nerve sparing has also a lot to do with the margins. That's why my mother was happy my surgery took a little longer than usual, she said "it must mean he took a really good look inside".

Mx is almost always the case after surgery as the surgeon does look for mets. In fact he can't really look for mets as they are not going to be in the area he is working in.

Nx is also common, as unless it has been agreed beforehand, then lymph nodes will not be removed and sent to the lab. (However, if a surgeon spots something "suspicious" then he might well remove a lymph node, but there may also be the issue here of whether or not he has received consent from the patient to do so! )
