Histopathologic Grading
Notes
Note 1: Histologic grading is used to distinguish between IVA and IVB anatomic stage/prognostic groups. It is of particular importance for mucinous carcinomas (morphology codes 8480, 8481, and 8490).
Note 2: Select the code for the highest grade from the primary tumor tissue as described on the pathology report prior to neoadjuvant treatment.
Note 3: The term "undifferentiated" should not apply to mucinous tumors because a tumor that makes mucin is, by definition, differentiated into mucin-producing tumor cells.
