Reportability--Anus: Is a final diagnosis on a pathology report of "squamous cell carcinoma of the anus, NOS" assumed to be a skin of anus primary or a primary of the anus?
Squamous cell carcinoma of the anus is reportable unless known or stated to be skin of anus.
CS Lymph Nodes--Lung: Do modifying terms such as "borderline" affect whether lymph nodes are coded as involved when they are used in conjunction with the descriptors listed in Note 2 (i.e., mass, adenopathy or enlargement) for lung primaries? See Discussion.
Lung primary: CT states "borderline" enlarged hilar lymph nodes. Note 2 in the Lung schema under CS Lymph Nodes does not address qualifiers.
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.
Do not code the hilar lymph nodes as involved in this case. "Borderline" enlarged hilar lymph nodes do not meet the clinical criteria for enlargement.
Histology (Pre-2007)/Flag--Pancreas: How is histology coded given that 8046 [non-small cell carcinoma] of the pancreas is not on the SEER Site/Type validation listing?
For tumors diagnosed prior to 2007:
Assign 8046 [non-small cell carcinoma] for "non-small cell carcinoma" of the pancreas. If necessary, override any site/type edits.
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.
Reportability--Hematopoietic, NOS: Is a "refractory cytopenia with excess blasts" discovered on a bone marrow biopsy reportable?
For cases diagnosed prior to 1/1/2010:
Refractory cytopenia with excess blasts (RCEB) is reportable. RCEB is the same disease process as refractory anemia with excess blasts, except there is more than one type of blood cell that is low (red, white, platelets).
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.
Reportability: Is a tumor reported as "neoplasm" or "neoplasia" per the pathology report, which is subsequently clinically referred to as "carcinoma" reportable? See Discussion.
Example 1: Lung-Wedge resection and subsequent left lower lobe lobectomy showed papillary epithelial neoplasia. Tumor board and subsequent reports state "nonsmall cell carcinoma of lung."
Example 2: Kidney-Partial nephrectomy showed epithelial neoplasm, clear cells with low grade cytology. Subsequent urology clinic notes state that path revealed clear cell renal carcinoma.
2004 SEER manual states that "cases clinically diagnosed are reportable. If the physician treats a patient for cancer in spite of the negative biopsy, accession the case." Do we also accession the case if primary site has been resected? Would diagnostic confirmation be coded 8 (clinical diagnosis only)?
Accession the case and code Diagnostic Confirmation as 8 [clinical diagnosis only]. Accession a case with negative pathology when the clinician is aware of the negative pathology and continues to refer to the case as malignant.
Multiple Primaries (Pre-2007): How many primaries? See Discussion.
5/05 perianal skin bx, 6/05 mapping bx perianal skin, 9/05 punch bx perianal skin: all positive for extramammary Paget Disease. 9/05 Perianal Excision of Paget w/V-Y flap repair. Path: Perianal and anal skin: Extramammary Paget disease associated with: Invasive adenoca of anal canal. Anal margins positive for invasive adenoca. Comment: invasive adenoca with local mucinous features involving the anal margin/end of specimen. This adenoca is in continuity with (associated with) extensively diffuse extramammary Paget disease. Unclear whether the adenoca represents a rectal primary with spread to perianal area, anal gland adenoca or mets. 12/05 AP resection-no residual Paget or invasive neoplasm.
For tumors diagnosed prior to 2007:
There is one primary.
Code the histology to 8542 [Paget disease, extramammary]. Code the primary site C210 [anus]. Histology rule 7 on page 87 of the 2004 SPCM applies in this case.
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.
Histology (Pre-2007)--Lung: How is a poorly differentiated non-small cell carcinoma with "squamoid differentiation" coded?
For tumors diagnosed prior to 2007:
Squamoid and squamous are synonymous. Squamoid is non-standard terminology. It means "squamous like" and is a synonym of squamous.
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.
CS Extension--Lymphoma: If bilateral tonsils are involved with lymphoma, is it one or two regions of involvement and how is extension coded?
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 cases diagnosed 1-1-08 and later: Assign CS extension code 10 [involvement of a single lymph node region]. Bilateral tonsils are one organ/site.
See Note 1 under CS Extension. Tonsil is coded the same as a lymph node region.
Multiple Primaries/Histology--Lymphoma: If an oral mucosa, right hard palate biopsy contains a composite lymphoma [low-grade follicular + chronic lymphocytic leukemia], how many tumors should be abstracted and how should the histology field(s) be coded?
For cases diagnosed prior to 1/1/2010:This is one primary. Assign code 9590 [Malignant lymphoma, NOS]. This is a composite lymphoma. Code to lymphoma when there is any solid tumor (in lymph nodes, tissue, etc.) Code to lymphoma, NOS since this is not purely follicular and there is no code for composite lymphoma.
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.
