Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/09/2010 [ Schema ]

CS Mets at DX

Note 1: The lesser sac of the peritoneum, or omental bursa, is the cavity in the abdomen formed by the lesser and greater omentum; the pancreas forms part of the posterior wall of the lesser sac.
Note 2: Celiac axis and splenic nodes are classified as distant for AJCC 7 staging. These nodes are now coded in CS Mets at DX.
