20091092 MP/H Rules-Lung: What is the Diagnosis Date, Diagnostic Confirmation and histology for the left lung mass?

Scenario: PET shows a 3 cm mass in the left lung and a 2.9 cm mass in the right lung. No reportable terminology in PET. The right mass is biopsied and shows adenoca. The left mass is not biopsied. Based on rule M6, this should be reported as two primaries. No additional information in medical record, pt expired.

20091090 First course treatment--Leukemia: Should an allogeneic stem cell transplant for acute myeloid leukemia be coded to 20 in the Hematologic Transplant and Endocrine Procedures? There is debate as to whether this procedure should be coded as a 12 in order to capture the allogeneic part of the procedure. Final Aug 10 2009
20091089 Histology--Hematopoietic: The final diagnosis on a bone marrow biopsy was "chronic lymphocytic leukemia with plasmacytic differentiation." Is this coded 9823/3, CLL/SLL or 9733/3, plasma cell leukemia? Final Aug 10 2009
20091088 MP/H Rules/Histology--Breast: How is histology coded? Right breast simple mastectomy, path: 2.5 x 1.5 x 1.5 cm metaplastic carcinoma with; the sarcomatous component is high grade sarcoma with focal areas of osteoid formation. The epithelial component is predominantly grade 2 DCIS. Final Oct 29 2009
20091087 Reportability--Appendix: Does the statement of "metastatic" make this reportable? Low-grade appendiceal mucinous neoplasm; Lt ovary, cul-de-sac, omentum, and small bowel: Metastatic low-grade appendiceal mucinous neoplasm. Per pathologist this is a borderline tumor of the appendix. Final Oct 02 2009
20091085 MP/H Rules/Histology--Breast: What is the correct histology code for this breast cancer case? Final diagnosis says, "Infiltrating duct carcinoma with apocrine features." What rule is used? See also discussion. Final Aug 10 2009
20091084 Primary site--Colon: How do you determine the correct subsite when there is conflicting information in different reports? See discussion for case example. In this case, the Operative report seems more correct. Are there priority rules for this for sites other than Head and Neck? Final Aug 10 2009
20091083 Grade/Cell indicator--Lymphoma: For pathology that states "anaplastic large cell lymphoma", is the grade code 4? The SPCM states cell indicator codes take precedence over grade/differentiation codes for lymphoma and leukemia cases. Final Aug 10 2009
20091082 Behavior--Breast: What is the correct behavior code for these 2 scenarios?

1. Path report for breast cancer has final diagnosis as 'DCIS' but the CAP protocol in the body of the report says 'microinvasion seen, T1mic.'

2. Path report says 'DCIS' in the final diagnosis and microinvasion is identified in the microscopic portion of the report, but it is not in CAP protocol format and not stated in the final diagnosis. These are path reports from lab only cases (not otherwise reported to the central registry).

Final Aug 10 2009
20091081 Reportability/Histology--Brain and CNS: Histology code 8825/1 (Inflammatory Myofibroblastic Tumor) is not listed in the ICD-0-3 Primary Brain and CNS Site/Histology listing for reportable Brain/CNS tumors. It seems this might be a reportable tumor? Final Aug 10 2009
