Note 1: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in the field Mets at DX.

Note 2: If the clinician says "adnexa palpated" but doesn't mention lymph nodes, assume lymph nodes are not involved.

Note 3: If either exploratory/definitive surgery is done with no mention of lymph nodes, assume nodes are negative.
