Grade, Differentiation/Priorities: Which has priority, the differentiation or the nuclear grade for a liver biopsy histology described as "well differentiated hepatocellular carcinoma, nuclear grade 3/4"?
Grade, Differentiation--Prostate: Has SEER officially changed the conversion code for Gleason score 7 to grade 3 [poorly differentiated] for cases diagnosed in 2003 or later?
MP/H Rules/Histology: In the MP/H Manual, where is the documentation indicating "focal" is not a term that can be used to code histology? See Discussion.
Grade--Liver: How should grade be coded for a liver lesion treated with radio frequency ablation (RFA) followed by a transplant showing moderately differentiated hepatocellular carcinoma? See discussion.
EOD-Size of Primary Tumor--Breast: When the pathology report does not specify dimensions for the invasive component, how is tumor size coded? See discussion.
Histology--Ovary: How is histology coded for an ovarian mucinous neoplasm of low malignant potential (borderline mucinous cystadenoma) that shows extensive intraepithelial carcinoma and focal microinvasion? See Discussion.
Multiplicity Counter: Are in situ tumors diagnosed more than 60 days after invasive tumors of the same site and histology included in the Multiplicity Counter?
