Report Question ID Question Discussion Answer Year
20130125 Reportability--Heme & Lymphoid Neoplasms: Is self-healing Langerhans cell histiocytosis (LCH) of the skin reportable?

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

This is a reportable primary. Langerhans cell histiocytosis (LCH) [9751/3] is a reportable neoplasm.

The term "self-healing" means that the neoplasm regressed without treatment. This is a known phenomenon.

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.

20051101 CS Extension--Cervix: How are "positive pelvic washings" coded for a cervical primary?

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.

According to the CS Steering Committee, positive pelvic washings for primary cervical cancer are not part of the staging criteria in the collaborative staging system (nor in TNM and FIGO). Document positive pelvic washings in a text field. The CS steering committee will add a statement to CS extension to clarify this for cervix uteri.

20021069 Histology (Pre-2007)--Breast: What code is used to represent the histology "infiltrating lobular carcinoma, solid and classical subtypes"?

For tumors diagnosed prior to 2007:

Code the Histology field to 8520 [Lobular carcinoma].

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.

20031114 EOD-Extension--Colon: How is this field coded for an appendical primary when the appendix has ruptured and intrapentoneal fluid is positive? For cases diagnosed 1998-2003: Code EOD extension as 85 [Metastasis]. Positive intraperitoneal fluid is equivalent to distant metastasis (implantation) for colon, including appendix, primaries. 2003

MP/H Rules/Histology--Appendix: What is the histology for an appendix resection diagnosis of "Malignant neoplasm of the appendix with the following features: Histologic type: Adenocarcinoma ex goblet cell carcinoid with mucin production (adenocarcinoma arising from goblet cell carcinoid)"? Is this histology best coded to a mixed adenocarcinoma/carcinoid tumor (8244/3)?

Code histology to combined carcinoid and adenocarcinoma (8244/3). The tumor is a mix of adenocarcinoma and carcinoid.

2016
20100074 Laterality--Melanoma: For a melanoma case, does the term "mid" imply that the tumor is in the midline when the site is the skin of back (trunk)? Yes. When the location is described as mid-back or mid-chest with no indication of left or right, assign laterality code 5 [midline]. 2010
20051113 Histology (Pre-2007): What is the difference between code 8244/3 composite carcinoid (combined carcinoid and adenocarcinoma) and 8245/3 adenocarcinoid tumor?

For tumors diagnosed prior to 2007:

Assign code 8244/3 [composite carcinoid] when there is a combination of adenocarcinoma and carcinoid tumor.

Assign code 8245/3 [adenocarcinoid] when the diagnosis is exactly "adenocarcinoid."

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--Brain and CNS: Is schwannoma of the extracranial part of a cranial nerve reportable? Some cranial nerves, like facial nerve, have intracranial and extracranial branches.

An extracranial schwannoma is not reportable. The schwannoma must arise on the intracranial part of the nerve to be reportable.

20061131 CS Lymph Node Examined--Lung: How is this field coded when a mediastinoscopy and lobectomy are performed and the pathology report indicates multiple lymph node fragments were removed as biopsy specimens and the lobectomy specimen revealed 3 interlobar lymph nodes?

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 Lymph Node Examined field to 98 [number unknown] because the biopsy information is not clear and as a result you do not know how many lymph nodes were examined.

20000430 Histology (Pre-2007)--Colon: What code is used to represent histology when the surgeon describes a sessile polyp and the final path diagnosis is stated as: "Rectal sessile polyp: Invasive moderately differentiated adenocarcinoma" (pathologist does not state that it is "arising in a sessile polyp")?

For tumors diagnosed prior to 2007:

Code the Histology field to 8210/3 [adenocarcinoma arising in a polyp]. The structure in which this adenocarcinoma is arising, is a polyp.

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.
