For tumors diagnosed prior to 2007:

Code the Histology field to 8263/3 [adenocarcinoma in a tubulovillous adenoma]. Because the mucinous component involves less than 50% of the tumor, the histology is not coded to mucinous. For mucinous only, the tumor must be at least 50% mucinous, mucin producing, to be coded to the specific 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.

For cases diagnosed 1998-2003:

Per AJCC, code spleen involvement which is demonstrated by:

1. Unequivocal palpable splenomegaly alone.

2. Equivocal palpable splenomegaly with radiologic confirmation (ultrasound or CT).

3. Enlargement or multiple focal defects that are neither cystic nor vascular (radiologic enlargement alone is inadequate).

If the spleen is proven to be involved, code extension for this case as 20 [Involvement of two or more lymph node regions on the same side of the diaphragm; Stage II].

If the spleen is not proven to be involved, code extension as 10 [Involvement of a single lymph node region; Stage I].

For cases diagnosed prior to 1/1/2010:Yes. Code the Grade, Differentiation field to 8 [NK cell] rather than 5 [T-cell]. Code the Histologic Type to 9719/38 [NK/T-cell lymphoma, nasal and nasal-type with Cell indicator of NK (8)].

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.

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 10 [confined to pancreas] because a scan supported the finding of no extension beyond the pancreas.

If the abstractor reviewing the medical record has scans, op reports, and/or pathology reports stating that the tumor is confined to the pancreas, code extension to 10 [confined to pancreas].

However, if the medical record only provides a patient history from a physician stating that the patient had localized pancreas, code extension to 30 [localized, NOS]. The NOS codes are used only when there is not enough information to code the specific codes (in this case, 10 or 20).

For cases diagnosed 1998-2003:

Using the EOD scheme for lymphoma, code the Extension field to 11 [Localized involvement of a single extralymphatic organ or site; Stage IE] for all 3 of these cases.

For the stomach lymphoma: There are 2 areas of lymphoma, but it is still confined to one site.

For the other 2 lymphomas: Intraluminal (mucosal) spread of the lymphoma never equals extension. The same phrase that was added to code 21, "Direct extension to adjacent organs or tissues", will be added to code 11 in the Collaborative Stage System. Neither "mucosal spread to a contiguous organ" or "direct extension into a nearby organ" affect staging. Both are still coded to 11 as long as there are no other sites of lymphoma involvement.

EOD code 80 is poorly written. It does not mean diffuse invovement or multiple tumors in a single organ but rather "diffuse disease in two or more organs."

For reportability, interpret "suspicious for but not diagnostic of" as NOT diagnostic of cancer.

The phrase "suspicious for the possibility of early invasive adenocarcinoma" may indicate that the case is in situ. If no further information is available, this is not reportable.

The site of the cancer diagnosis does not change the interpretation.

For cases diagnosed 2001-2006:

Borderline tumors are not reportable to SEER as of 2001. If you are collecting them in your registry, use the following procedure: Exception 1 in the SEER Program Code Manual, 3rd Edition, responds to the issue of processing ovarian tumors. Simultaneously occurring ovarian tumors with a single histology are coded as one primary. In the case you cite, the right ovary primary occurred 7 months after the left ovary primary. This is not simultaneous, so it would be counted as a second primary.

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.
