Collaborative Stage

Note 1: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in CS Mets at DX. Regional nodes include bilateral and contralateral involvement of named nodes.
Note 2: When both FIGO stage and regional lymph node detail are available, record the code with regional lymph node detail in preference to a statement of FIGO stage.
Note 3: If either exploratory or definitive surgery is done with no mention of lymph nodes, assume nodes are negative.
Note 4: If the clinician says "adnexa palpated" but does not mention lymph nodes, assume lymph nodes are not involved.
