Grade, Differentiation--Brain and CNS: Can grade IV be implied for brain primaries with the histology of glioblastoma multiforme, even if there is no statement of grade in the path report? See discussion.
EOD-Extension/SEER Summary Stage 2000--Kidney/Eye: What codes are used to represent these fields for simultaneous bilateral Wilms tumor or simultaneous bilateral retinoblastoma?
Diagnostic Confirmation: Is it appropriate to code this field to "radiography" confirmation when a CT scan does not actually contain a diagnosis of malignancy, however, the discharge diagnosis in the medical record of "probable malignancy" is likely based on the abnormal CT findings? See discussion.
Histology (Pre-2007)--Colon: What code is used to represent histology when the surgeon describes a sessile polyp and the final path diagnosis is stated as: "Rectal sessile polyp: Invasive moderately differentiated adenocarcinoma" (pathologist does not state that it is "arising in a sessile polyp")?
EOD-Size of Primary Tumor--Breast: For breast cancer cases, is code 002 [Mammography/xerography diagnosis only with no size given (tumor not clinically palpable)] to be used only when there is no work-up beyond a clinical one? See discussion.
EOD-Clinical Extension--Prostate: How do you distinguish between clinical extension codes of 10, 13, 14, and 20 for cases with a benign prostate per digital rectal exam that appear localized after TURP/prostatectomy? Can the clinical extension code of 10 be used if the term "microscopic carcinoma" is noted in the pathology report without also mentioning "foci" or "Stage A" for clinically inapparent tumors?
