Self Instructional Manual for Cancer Registrars - SEER - National ...

Example G11 can be abstracted as follows:
Example Gll: 3/18/91. Autopsy Rpt. N91-2000: Adenocarcinoma of the gallbladder with
extension into liver and hepatic flexure.
Nodules on internal surface of bowel.
Comments.
Did malignancy extend to hepatic flexure (microscopic description) or metastasize
to hepatic flexure (final diagnosis)? Report as direct extension of tumor. "Direct
extension of tumor" agrees with the microscopic description and is supported by the
note on the diagram of the abdomen which says that the right colon was matted into
the liver. (The distinction between direct extension and metastasis, non-contiguous
disease, will be discussed in a later instructional manual.)
