For tumors diagnosed prior to 2007:

Code the Histology field for the first example to 8140/2 [Adenocarcinoma, NOS, in situ] and for the second example to 8077/2 [AIN, grade III]. For both of the cases code the Grade, Differentiation field to 9 [Cell type not determined not stated or not applicable]. The 6th digit (grade code) of ICD-O-3 describes how much or how little a malignant tumor resembles the normal tissue from which it arose. In contrast, "grade" is used in the examples above to describe the degree of dysplasia, from mild dysplasia (low grade) to severe dysplasia (high grade). Do not record the degree of dysplasia in the 6th digit grade field.

For tumors diagnosed 2007 or later, refer to the MP/H rules for histology coding instructions. 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.

For cases diagnosed 1998-2003:

No. The inferred descriptions of noninvasion apply to bladder cases only.

"Likely cancerous" is NOT reportable.

The CoC, NPCR and SEER have agreed to a strict interpretation of the ambiguous terms list. Terms that do not appear on the list are not diagnostic of cancer.

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

For bilateral malignant pleural effusion, code the ipsilateral malignant effusion in CS Extension and the contralateral malignant effusion in CS Mets at Dx. Assuming the bilateral pleural effusion is the furthest extension in this case, code CS Extension to 72 [Malignant pleural effusion]. Code CS Mets at Dx to 40 [Distant mets, NOS].

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

This case should be accessioned as one primary. Per Rule PH26, code the primary site to bone marrow (C421) when lymphoma is present only in the bone marrow. (We assumed all available physical exams, scans, and other work-up were negative for lymph node, tissue, or organ involvement.) Histology is coded to 9680/3 [Diffuse large B-cell lymphoma (DLBCL)]. Under the Alternate Names section of the Heme DB, a synonym for DLBCL is B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma.

SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.

The Solid Tumor Rules for Lung rule H4 applies. Per Table 3, page 12, third column on adenocarcinoma row, adenocarcinoma, acinar predominant is coded to 8551/3.

For tumors diagnosed prior to 2007:

According to SEER rules, abstract as one primary because although these sites have separate topography codes in ICD-O-3, they were coded to the same three-digit topography code in the first edition of ICD-O (SEER Program Code Manual, 3rd Edition, page 8, Exception B). Simultaneous lesions of the same histology in trachea and lung are one primary. Code the primary site to C399 [Ill-defined sites within respiratory system].

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.

For cases diagnosed 1998-2003:

Code the EOD-Size of Primary Tumor field as stated by the pathologist in the final pathologic diagnosis. If the size of the tumor is the same as the size of the polyp, assume the polyp was completely replaced by tumor.

For cases diagnosed prior to 1/1/2010:

Code the Histology field to 9989/3 [myelodysplastic syndrome] and the Date of Diagnosis field to June 2001.

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.

Code histology to adenocarcinoma, NOS (8140/3). The World Health Organization and the College of American Pathologists no longer recognize non-mucinous carcinoma/adenocarcinoma, NOS. Pathologists are discouraged from using this term. Microinvasive/minimally invasive lung tumors have very specific criteria and these criteria do not apply to non-mucinous carcinoma, NOS.
