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.
MP/H Rules--Corpus uteri: How is histology coded for an endometrial tumor described as an "endometrioid adenocarcinoma with prominent squamous metaplasia"?
MPH rules--Rectum: How is the number of primaries to be determined when a treatment plan has been completed, but it is not possible to determine whether there was a disease-free interval between occurrences? See Discussion.
Primary Site/CS Extension--Lymphoma: How are these fields coded for an epidural lymphoma that extends into the bone marrow of the adjacent vertebral body?
MP/H Rules/Histology--Thyroid: How many primaries are to be reported and what histology is to be coded for an anaplastic/undifferentiated thyroid carcinoma with sarcomatoid transformation likely arising in association with a papillary thyroid carcinoma? Thyroid contains one tumor: 12.5 cm in greatest dimension...almost completely replaces entire thryroid gland.
Diagnostic Confirmation/Histology--Hematopoietic: How are these fields coded when the final pathologic diagnosis for a bone marrow biopsy differs from the final clinical diagnosis of a hematopoietic disease? See Discussion.
