Reportability/Date of diagnosis--Small intestine: Is this case reportable? Widely metastatic gastrointestinal stomal tumor (GIST) was diagnosed at an out-of-state facility in 2017 and referred back to a hospital in our state for chemotherapy where there is a history of a small bowel resection of GIST of uncertain malignant potential (8936/1) doneat the hospital in 2003. If so, is the diagnosis date 2003 or 2017? See Discussion.
Reportability/Date of diagnosis--Thyroid: Is category Thyroid imaging reporting and data system (TI-RADS) 4 (4a/4b) or TI-RADS 5 on imaging diagnostic of thyroid cancer, and if so, can we use the date of the impression on the scan that states either of these categories as the diagnosis date?
Reportability/Diagnostic Confirmation--Leukemia: What is the diagnostic confirmation if a positive BCR/ABL result is diagnostic of a malignancy in a patient suspected to have chronic myelogenous leukemia? See Discussion.
Reportability/Diagnostic Confirmation--Melanoma: Would a shave biopsy diagnosis of "highly suggestive of early melanoma", followed by a re-excision diagnosis of "no residual disease", be SEER reportable if the clinician referred to the case clinically as a melanoma? If so, what would the Diagnostic Confirmation be? See discussion.
Reportability/Diagnostic Confirmation: If a diagnosis based solely on positive flow cytometry is reportable even if a bone marrow biopsy is negative, how is diagnostic confirmation coded?
Reportability/Diagnostic Confirmation: If a physician signs a case out as "precancerous melanosis of the face" (8741/2) and there is no microscopic confirmation of the disease, is this a reportable clinical diagnosis?
Reportability/EOD--Ovary: Bilateral ovary shows gonadoblastoma with germ cell neoplasia in situ (9064/2). Pathology report clearly states in situ. Is this case reportable?
If this case is reportable, how would you code Extent of Disease (EOD) Primary Tumor and SEER Summary Stage (SS)? In situ code 000 for primary tumor and code 0 for SS 2018 is not given as an option.
Reportability/Grade, Differentiation: Does the term "grade 0" refer to differentiation or does its use as a modifying phrase in the final diagnosis of "grade 0 immature teratoma" impact reportability?
