Grade, Differentiation--All Sites: Why was the decision made not to code all "3-component differentiation systems" the same way that Bloom-Richardson is coded? For example, SEER codes a low grade BR to 1 for the Differentiation field and a low grade for other grading systems to 2. See discussion.
Surgery of Primary Site--Breast: How is this field coded for a BILATERAL nipple sparing mastectomy given that SINQ 20110094 indicates that a nipple sparing mastectomy should be coded to 30 [subcutaneous mastectomy] but there is no code for bilateral subcutaneous mastectomies?
Reportability--Ovary: Is immature teratoma of the ovary reportable if a subsequent comment states that "the teratoma shows immature neuroepithelium, but no malignant elements"?
Grade: Can the nuclear grade value be coded in the grade field for any site, or is it restricted to sites where it is specifically listed as an option in the coding manual, i.e., breast, kidney, urinary sites, etc.?
Ambiguous terminology/Reportability--Kidney: Is a case reportable if a biopsy diagnosis of "suggestive of oncocytoma, malignant neoplasm cannot be excluded" follows a CT scan that was read as "suspicious for carcinoma"? See Discussion.
Reportability--Melanoma: Is a skin excision final diagnosis of "melanocytic tumor with uncertain malignant potential" reportable if the path COMMENT states the initial shave biopsy diagnosis was "melanocytic tumor with uncertain malignant potential [minimal deviation melanoma]"? See Discussion.
Reportability--Ovary: Does the ICD-O-3 term "stromal endometriosis" [8931/3] always imply a reportable malignant disease process if the pathologist also states there is "no evidence of carcinoma" in the same report? See Discussion.
MP/H Rules/Reportability--Ovary: Should an ovarian tumor with the histology of mixed epithelial borderline tumor with multiple foci of intraepithelial carcinoma be accessioned based on the presence of a foci of intraepithelial carcinoma? See Discussion.
