If it is not clear where the tumor originated, use the following criteria to distinguish ovarian primaries from peritoneal primaries.

The primary site is probably ovarian, unless:

--Ovaries have been previously removed

--Ovaries are not involved (negative)

--Ovaries have no area of involvement greater than 5mm.

Descriptions such as "bulky mass," "omental caking" probably indicate an ovarian primary.

Descriptions such as "seeding," "studding," "salting" probably indicate a peritoneal primary.

Assign code 60 for a primary in the head of the pancreas extending to the superior mesenteric artery. CS Extension code 54 should be Superior mesenteric VEIN and code 60 should be Superior mesenteric ARTERY. An errata will be issued by CS. In addition, extension 54 indicates resectable disease and code 60 is not resectable.

Assign CS Extension code 67 [Adrenal gland from renal pelvis] for adrenal extension from renal pelvis -- T4 and regional direct extension.

For tumors diagnosed prior to 2007:

Yes, code this case to 8500/31 [Well differentiated invasive ductal carcinoma]. Code the histology stated on the pathology report from the procedure removing the most tumor tissue. A lumpectomy will usually provide more tumor tissue than a core needle biopsy.

First, determine which specimen contains the most TUMOR tissue -- in this case the lumpectomy. Next, apply the histology coding rules to the diagnosis on that pathology report. The rationale is that a diagnosis from a smaller specimen will be less accurate and less representative of the true histology compared to a larger tumor specimen.

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 tumors diagnosed prior to 2007:

The combination of C381 [anterior mediastinum] and 8246 [neuroendocrine carcinoma] will be removed from the list of "impossible" site/histology combinations. There are rare cases of neuroendocrine carcinoma of the anterior mediastinum. As illustrated in the discussion, verify that the primary site is anterior mediastinum, the histology is neuroendocrine ca, and document those findings in the text.

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 prior to 1/1/2010:The combination of a primary site C809 with a Grade, Differentiation code of 6 when used for a lymphoma will not fail SEER edits. Avoid coding primary site to C809 when possible. Code primary site for the example above to C761 [Chest wall, NOS]. The chest wall is the only area of involvement, except for "liver nodules." Liver is an unlikely primary site for 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.

For tumors diagnosed prior to 2007:

The presence of numerous/multiple polyps is not necessarily adenomatous polyposis coli. Adenomatous polyposis is an extreme condition usually characterized by the presence of hundreds of polyps and should be identified as such either clinically or pathologically.

Look for the term "Familial adenomatous polyposis," FAP or one of its synonyms:

Adenomatosis of the colon and rectum [ACR]

Familial adenomatous colon polyposis

Familial colonic polyposis

Multiple familial polyposis

In the absence of these terms, the following probably indicate a diagnosis of FAP:

Hundreds of adenomatous polyps throughout large intestines, and at times, throughout the digestive system

Development of polyps as early as ten years of age, but more commonly at puberty

History of colectomy

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.

Yes. Based on the information provided above, the in situ component is "mininmal" for the purpose of coding Breast CS Site Specific Factor 6. The phrase "no extensive intraductal component" suggests that there is some intraductal carcinoma present.

If the tumor is described as a "cystic mass" and only the size of the entire mass is given, code the size of the entire mass, because the cysts are part of the tumor itself.

Please note: Ovarian cancer stage is not based on tumor size.
