Reason No Cancer-Directed Surgery--Hematopoietic, NOS: Is this field always coded to 1 [not performed, not part of first course] for leukemias & other hematopoietic diseases?
Reason no surgery of primary site/First course treatment: If the Reason no Surgery of Primary Site field is coded as 7 (refused), must the other treatment options (radiation, chemo, hormone) also be coded as 7? See Discussion.
Reason no treatment/Surgery of Primary Site: Does the "Reason for No Cancer-Directed Therapy" field only relate to the "Surgery of Primary Site" field? If so, for what diagnosis years is that effective? Have SEER's coding guidelines changed over time? See discussion.
Reportability--Anal canal: Are squamous cell carcinomas arising in a condyloma of the rectum reportable or should we assume that the site is skin of anus or perianal area and not reportable?
Reportability--Anus: Is a final diagnosis on a pathology report of "squamous cell carcinoma of the anus, NOS" assumed to be a skin of anus primary or a primary of the anus?
Reportability--Appendix: Is a low grade mucinous neoplasm of uncertain malignant potential with an in situ mucinous cystadenoma component reportable? See Discussion.
Reportability--Appendix: Is a metastatic low-grade appendiceal mucinous neoplasm reportable if the pathologist states that it is a borderline tumor of the appendix? See Discussion.
Reportability--Appendix: Is a pathologic final diagnosis of an appendix with "well-differentiated neuroendocrine tumor (carcinoid)" reportable? See discussion.
Reportability--Brain and CNS: Are "spinal" schwannomas reportable if stated to be extradural, vertebral nerve sheath, or of specific vertebrae? See Discussion.
