CS Site Specific Factor 4--Prostate: If PAP is not mentioned in the chart, should Site Specific Factor 4 be coded to 999 [unknown or no information] or 000 [test not done]?
Primary Site--Lymphoma: How should this field be coded when a diffuse large B-cell lymphoma is found in the femur and in the soft tissue of the anterior chest wall but all CT scans are negative for lymphadenopathy?
Primary Site--Ovary/Peritoneum: Should this field be coded to ovary or peritoneum when the bulk of the tumor is in the peritoneum and there is only surface involvement of the ovary?
Multiple Primaries (Pre-2007)--Colon: What is the number of primaries for a case of familial polyposis with at least three separate tumors having invasive adenocarcinoma, one in the rectum? See Discussion.
EOD-Clinical Extension--Prostate: Should this field be coded to 15 [Tumor identified by needle biopsy for elevated PSA] or 30 [Localized, NOS] when the only information is from a biopsy positive pathology report that includes the clinical history of "PSA elevated, DRE negative," with no mention of an ultrasound being performed?
Multiple Primaries--Lymphoma: How many primaries should we abstract when Single Versus Subsequent Primaries table indicates one primary but special pathological studies indicate two primaries? See Description.
Multiple Primaries (Pre-2007)/Date of Diagnosis--Bladder: How is date of diagnosis coded when metastases consistent with a bladder primary are found more than a year after a diagnosis of non-invasive bladder cancer? See Description.
EOD-Extension--Retroperitoneum: Does the presence of "necrotic masses, NOS" in the blood, which are not pathologically evaluated, affect the coding of this field? See Description.
