Primary Site/Histology (Pre-2007)--Mediastinum: How do we code these fields for a case described as a "neuroendocrine carcinoma" of the "anterior mediastinum" without failing the SEER "impossible" site/histology combination edit? See Discussion.
Two different facilities state that the patient has "neuroendocrine carcinoma of the anterior mediastinum." This coded combination failed SEER edit (SEERIF38). We can not correct it because that edit flag does not appear on our system. Both facilities indicate that the mediastinum is the primary. In addition, there is text to support both the histology and primary site codes.
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.
Histology (Pre-2007)--Colon: Must a case be specifically labeled "familial adenomatous polyposis" or is the mere presence of numerous/multiple polyps sufficient for coding the histology to FAP?
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.
Ambiguous Terminology/Reportability: Is the phrase "indicative of cancer" SEER reportable?
No. The phrase "indicative of cancer" alone is not a definitive cancer diagnosis. The word "indicative" is not on the list of ambiguous terms that is equivalent to a diagnosis of cancer.
Ambiguous Terminology: Is the expression "has the markings of a malignancy" a clinically reportable term? See Discussion.
12/02 Baseline mammogram: spiculated mass with associated marked retraction located in UOQ lt breast. This has the markings of malignancy. Several microcalcifications in outer aspect of rt breast. BI-RADS 5 higly suggestive of malignancy.
Do not accession cases using only the term "has the markings of malignancy." This term is not on the list of ambiguous terms that are reportable. If the term does not appear on either the reportable or not reportable list, the term is not diagnostic of cancer. Do not accession the case.
Please see SINQ 20010094 in reference to BI-RADS terminology.
CS Tumor Size--Unknown & ill-defined site: For an unknown primary site, should this field be coded to 000 [No mass/tumor found] or 999 [Unknown; size not stated; not stated in patient record]?
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.Code the CS Tumor Size field to 999 [Unknown; size not stated; not stated in patient record] when the primary site is unknown.
There is a discrepancy in Part I of the CS Manual on page 27, rule 5g, which says that primary site C80.9 should be coded as 888 not applicable. The CS Steering Committee has decided that the last line about unknown and ill-defined sites should be deleted from rule 5g. This issue will be addressed in a CS errata to be distributed in July 2004.
First Course Treatment/Immunotherapy--Colon: Can "Sandostatin" be coded for treatment of carcinoid tumors of the colon because it flushes tumor cells from the colon in addition to controlling diarrhea?
Do not code Sandostatin (Ocreotide Acetate) as treatment. This is an ancillary drug used to treat symptoms of diarrhea. SEER Book 8 is undergoing revision and will include this change.
Histology--Hematopoietic, NOS: When the histology is described in both WHO and FAB terms, which terminology has priority to code this field? See Discussion.
Example: Bone marrow biopsy was reported as: "Markedly hypercellular marrow aspirate with myelodysplastic alterations morphologically consistent with refractory anemia (FAB) or refractory cytopenia with multilineage dysplasia (WHO)."
For cases diagnosed prior to 1/1/2010:Give preference to the WHO terminology when both are used in the final pathology diagnosis. The WHO classification of tumors is the current standard and is recommended by the College of American Pathologists.
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.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)/Grade, Differentiation--Thyroid: How many primaries, with what histologies should be coded when a thyroidectomy reveals "anaplastic carcinoma" and "papillary carcinoma" occurring as two separate tumors? See Discussion.
Example: Thyroidectomy revealed anaplastic carcinoma of the thyroid with mets to lymph nodes. The path report stated that the thyroid specimen also contained a small papillary carcinoma. Differentiation for the papillary carcinoma was not stated.
For tumors diagnosed prior to 2007:
Accession and code as two thyroid primaries:
Anaplastic carcinoma [8021/34]
Papillary carcinoma [8260/39]
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.
