Histology (Pre-2007): What code is used to represent the histology "adenocarcinoma, undifferentiated, with sarcomatoid features"? See discussion.
Is the case more accurately coded with histology of adenosarcoma [8933/34] or adenocarcinoma, undifferentiated [8140/34]? Should "sarcomatoid" be interpreted as sarcoma?
For tumors diagnosed prior to 2007:
Code the Histology field to 8140/34 [adenocarcinoma, undifferentiated]. Sarcomatoid means sarcoma-like and should not be used in coding histology.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Date of Diagnosis--Lung: Based on Note 7 in the lung EOD, should the Date of Diagnosis field be coded to an earlier CT scan date with a reported diagnosis of "RUL mass with mediastinal lymphadenopathy" or to the later biopsy date with a reported diagnosis of small cell carcinoma? See discussion.
Note 7 states that "mediastinal lymphadenopathy" indicates involved lymph nodes for lung primaries. Should the date of diagnosis be back-dated to the date of the scan?
For cases diagnosed 1998-2003:
No, code the Date of Diagnosis field to the later biopsy date. Note 7 is intended for use in coding the EOD-Extension field, not the Date of Diagnosis field. The earlier scan has a diagnosis of RUL "mass" not a "malignancy" so the fact that there is mediastinal lymphadenopathy mentioned in that scan is not used to help determine date of diagnosis.
Scope of Regional Lymph Node Surgery/EOD-Number of Regional Nodes Examined: What codes is used to represent these fields when the surgeon states that a "lymph node dissection" was done, but no nodes are identified in the pathology report?
For cases diagnosed 1/1/2003 and after: Code the Scope of Regional Lymph Node Surgery field to 3 [Number of regional lymph nodes removed unknown or not stated; regional lymph nodes removed, NOS] and code the EOD-Number of Regional Nodes Examined field to 00 [No nodes examined].
The surgery fields reflect the procedures the physician performed. The EOD fields reflect the results of those procedures.
EOD Fields--Lymphoma: Was MALT Lymphoma [9715/3 (ICD-O-2) and 9699/3 (ICD-O-3)] inadvertently excluded from SEER EOD manual, top of page 180?
For cases diagnosed 1998-2003:
Yes. Use the scheme on page 180 for MALT lymphoma. The ICD-O-2 morphology code 9715 was omitted in error. It should have been added when the EOD was printed in 1998.
Grade, Differentiation--All Sites: Should we take the grade from a TNM staging form over a grade stated in a pathology report when the grade mentioned on the TNM staging form is a higher grade (e.g., Pathology report diagnosis is moderately differentiated adenocarcinoma, Gleason's 3+3=6, but the physician checked "poorly differentiated" on the TNM form)?
Code the Grade, Differentiation field to 2 [moderatley differentiated]. Code from the pathology report over the TNM staging form. If you do not have access to the path report, use the grade from the TNM form.
EOD-Extension--Bladder: Both papillary transitional cell ca in situ and sessile (flat) transitional cell ca in situ are diagnosed simultaneously in the bladder. We code the higher histology (8130/2). For extension, do we use the code that corresponds to the histology (01), or to the higher extension code (06)?
For cases diagnosed between 1998-2003:
Code the EOD-Extension field to 06 [sessile (flat) (solid) carcinoma in situ], the higher extension code.
Grade, Differentiation--Bone Marrow: Can we use the AJCC Cancer Staging Manual, which lists myeloma as a B cell neoplasm under non-Hodgkin lymphomas, to code Grade, Differentiation field for myeloma to B-cell (code 6)?
For cases diagnosed prior to 1/1/2010:
No. Myeloma is a malignancy of plasma cells. Plasma cells are the daughters of B cells. So technically it would be correct to call them B cell, but that is not common usage.
Cell marker (phenotype) should be coded in the Grade, Differentiation field for only leukemias and lymphomas, as classified in the ICD-O-3. In the ICD-O-3, myeloma is listed under Plasma Cell Tumors, not Lymphomas. When a cell marker is coded for a leukemia/lymphoma it should be coded only from pathology and/or cytology reports.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Grade, Differentiation--Unknown Site: Is grade coded to 9 [Cell type not determined, not stated or not applicable] for all unknown primaries?
Most unknown primaries would be coded to grade 9 [Cell type not determined, not stated or not applicable] in the Grade, Differentiation field unless the case is coded to one of the histologies for which the grade is implied, such as undifferentiated carcinoma, NOS [802034].
Spanish Surname or Origin: If Asians, Blacks and Whites with non-Spanish surnames are born in a Spanish country, is this field coded to Spanish or non-Spanish? See discussion.
For example, how do we code Miyako Mitsubishi with race listed as Japanese who was born in Peru or Sylvia Shapiro with race listed as White who was born in Argentina?
For both cases, code the Spanish Surname or Origin field to 0 [Non-Spanish/Non-Hispanic]. Persons with non-Spanish surnames would not be coded as being Spanish solely because they are born in a Spanish country. Do not code Spanish ethnicity based only on birthplace. Place of birth is a separate data item and it can be used in data analysis to identify this particular group of people.
