EOD-Extension--Pancreas: How do you code extension when a mass is described on exploratory laparotomy as compressing the duodenum, arising in the head of the pancreas, "extending around" the superior mesenteric vein and artery, and "encasing" the portahepatis?
EOD-Extension--Pancreas: How do you code extension when CT scan shows a mass in the head of the pancreas "encompassing" the hepatic branch of the celiac artery? See discussion.
EOD-Extension--Pancreas: How would you code extension for the following non-surgically treated pancreas primaries? None of these cases has TNM staging to assist with classifying the extent of disease. See discussion.
EOD-Extension--Pancreas: If the tumor involvement for a case falls between two different regional extension codes, should we code to the lesser of the two codes or should we code extension as unknown? See discussion.
EOD-Extension--Retroperitoneum: Does the presence of "necrotic masses, NOS" in the blood, which are not pathologically evaluated, affect the coding of this field? See Description.
EOD-Extension--Small Intestine: How do we interpret a pathology description of "extending through serosa and forming masses in the periserosal tissue" for a jejunum primary?
