For cases diagnosed prior to 1/1/2010:Code the Diagnostic Confirmation field as 1 [positive histology]. Code the ICD-O-3 morphology based on the clinician's statement.

The code in Diagnostic Confirmation pertains to the best method used to confirm the presence of cancer over the entire course of the disease. Therefore, if a bone marrow report confirms cancer, code 1 [positive histology] in Diagnostic Confirmation.

Code the histology using all of the information available. The clinician has access to all of the information relating to this case. The pathologist had only the bone marrow. Code the histology recorded by the clinician.

For cases diagnosed 1/1/10 and later, 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 prior to 1/1/2010:This is a single primary. The histology code is 9596/3 [composite Hodgkin and non-Hodgkin lymphoma].

According to the Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, 9596/3 followed by 9670/3 is one primary.

For cases diagnosed 1/1/10 and later, 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 2007 or later:

Abstract two primaries in this case, 2002 and 2007.

The first primary was diagnosed in 2002. The 2006 diagnosis would not be a new primary according to the rules in effect at that time (2004 SEER manual, page 11, rule 5, exception 1).

Use the current MP/H rules to compare the 2007 diagnosis to the 2002 diagnosis. Start with rule M3 and stop at rule M10. The 2007 diagnosis is a separate primary.

For cases diagnosed 2007 or later:

A metastasis was diagnosed in 2007. The 2007 MP/H rules do not apply to metastases.

Change the behavior code of the 2000 diagnosis. The breast cancer diagnosed in 2000 must have been invasive based on the metastasis in 2007.

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.Follow the current CS instructions regarding ambiguous terminology. "Abuts" and "encased/encasing" are not involvement.

The American College of Surgeons Commission on Cancer provided the following in response to this question: This concept can be considered for CS version 2, but it would need to be made in conjunction with acceptance of that same theory in AJCC 7th Edition so that the stage can be derived. Many times what can be defined and accepted in a closed environment of a single institution research project cannot be duplicated and accepted across the nation and in every community facility. Would pathologists specify the > or < 180 degree involvement in every pathology report? It would also have to be reviewed to see if this idea has been accepted by the larger oncology community, or just the idea of a single institution.

Assign code 7 [Spanish surname only] when the last name is on the Spanish Surname list. This includes cases for which the birthplace is Brazil, Portugal or the Philippines and there is no text to further clarify ethnicity.

The instruction to use code 0 [Non-Spanish/Non-Hispanic] in the SEER manual on page 51 (#2) applies when the only information available is the birthplace or a statement of "Portuguese," "Brazilian" or "Filipino."

For cases diagnosed 2007 or later, code the histology 8140 [Adenocarcinoma]. Rule H6 applies because the final diagnosis is not "mucinous adenocarcinoma" and the percentage of mucinous adenocarcinoma is not stated.

Rule H13 does not apply because "component" is not a term that indicates a specific histology.
