Primary site/Histology--Heme & Lymphoid Neoplasms: How are these fields coded for a precursor T lymphoblastic leukemia involving the bone marrow and peripheral blood (per pathology) with a clinically noted large mediastinal mass and cervical lymphadenopathy? See Discussion.
Primary Site/Histology--Lymphoma: How are these fields coded when the final diagnosis per the pathology report is, "Soft tissue and skeletal muscle, left thigh--Large B cell lymphoma with polyclonal and mature t-cells, involving the soft tissue"?
Primary site/Histology: Do the 4/1/09 changes in the ICD-O-3 Site/Type Validation table regarding the coding of primary site for intestinal type adenocarcinoma mean that the former valid site/histology combinations are now impossible and require review from a given diagnosis date forward? See Discussion.
Primary site/Histology: Does SEER accept the site/type combination of lymph nodes (C77.0-C77.9) with the histology of either 9823 (B-cell chronic lymphocytic leukemia/small cell lymphocytic lymphoma) or 9827 (Adult T-cell leukemia/lymphoma)? See Discussion.
Primary site/Reportability--Breast: Is a "right nipple skin" biopsy that demonstrates squamous cell carcinoma reportable using a primary site of C500? See Discussion.
Primary Site/Reportability: What is the primary site and reportability status of a "pancreatic endocrine neoplasm" that arises in the heterotopic pancreas of the splenic hilum that is stated to be a "well-differentiated endocrine tumor, uncertain behavior per the WHO classification"? See Discussion.
Primary Site/Sarcoma--Breast: Is the primary site coded to C504 [upper-outer quadrant of breast] or C493 [ Connective, subcutaneous and other soft tissue of thorax ] for a tumor described as a "high grade soft tissue sarcoma present in the upper outer quadrant of breast"?
Primary Site/Summary Stage 2000/EOD-Extension--Lymphoma: How are these fields coded when a CT Impression states: Large retroperitoneal/abdominal mass resulting in extra-hepatic biliary obstruction & bilateral urinary tract obstruction & encasement of major vessels most c/w lymphoma? See Discussion.
Primary Site/Surgery of Other Site--Leukemia: If hairy cell leukemia is diagnosed at splenectomy, and 1 month later a bone marrow confirms the same diagnosis, is the primary site coded to spleen or bone marrow? If the site is bone marrow, is the splenectomy coded to 2 (regional) or 4 (distant) in the surgery field?
