20081058 Histology--Brain and CNS: How is the histology coded for a mixed glioneuronal tumor, such as a papillary glioneuronal tumor? The best code available at this time is 9505/1 [Ganglioglioma, NOS]. 2008

CS Tumor Size: Can an 'ulcerated mass' be used to code CS tumor size? See Discussion.

The CS Manual (p. 26, 4.a.) states do not code the size of the polyp, ulcer or cyst. However it states that a 'cystic mass' can be used to code TS if it is the only size given. Scopes Text: 'ulcerated' mass based at anal verge & ext 3-4 cm up into rectum.

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.Do not code CS Tumor size using the size of an ulcerated mass.

    		20081066 Multiplicity Counter/Type of Multiple Tumors--Breast: How should these fields be coded when path shows a 1.2 cm infiltrating carcinoma with lobular features and several foci of infiltrating lobular carcinoma [7 foci described as multifocal], 1 large focus, and numerous foci of LCIS and CIS with lobular and ductal features? Should we count the foci or separate tumor nodules, ignore them, or code unknown values for these fields? See Discussion.

    Scenario: 10/17/07: Right axilla soft tissue bx - infiltrating mammary ca with lobular features arising within apparent breast tissue present within axilla. Tumor size 1.2 cm. 11/3/07: Right breast, reexcision lumpectomy - Several foci of infiltrating lobular CA. (2) foci & (5) foci within specimen (multifocal). (1) large focus also present. No lymphovascular invasion identified. Numerous foci LCIS. Pleomorphic LCIS & CIS with lobular and ductal features. Margins free of invasion however margins diffusely involved with LCIS.

    When do you count foci or separate tumor nodules, when do you ignore them, and when do you code unknown values for these fields? Coding instruction 3b states, "When the tumor is multifocal or multicentric and the foci of tumor are not measured, code as 99." Instruction 4b states, "Use code 01 when there is a single tumor with separate foci of tumor." Finally, instruction 6b states, "Use code 99 when the tumor is described as multifocal or multicentric and the number of tumors is not given," which seems to imply that if we know the number of tumors, we would code that number.

    Multiplicity Counter: Use instruction 4b. Since there is one measured tumor and the foci were not measured, code the multiplicity counter 01 [One tumor only].

    Type of Multiple Tumors: Code Type of multiple tumors 00 [Single tumor].

    		20081132 MP/H Rules--Breast: What is the histology code for a breast tumor that is ductal ca with focal squamous differentiation? See Discussion. SINQ 20021062 states for cases Dx'd prior to 2007, use 8570. Is 8570 also used when the squamous differentiation is focal? For cases diagnosed 2007 or later, use rule H14 and code the histology 8500 [duct carcinoma]. Ignore histologies described as "focal," "focus," or "foci." This instruction will be added to the histology rules in the upcoming revision of the MP/H manual. 2008

    CS Extension--Brain and CNS: How is CS Extension coded for a malignant meningioma that demonstrates extension into adjacent brain tissue?

    For malignant brain tumors, code 60 represents extension into the meninges. Would code 60 be the correct code for extension from a malignant meningioma into brain tissue?

    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.Assign CS extension code 60 for malignant meningioma with extension to adjacent brain tissue.

    According to the I&R, this section of CS was taken directly from SEER Summary Staging, since AJCC does not have a staging system for these tumors.

    		20081133 MP/H Rules--Breast: What histology code is used for lobular carcinoma, pleomorphic type? For cases diagnosed 2007 or later, use rule H14 and code the histology 8520 [lobular carcinoma]. 8520 is the only ICD-O-3 code for lobular carcinoma. There are no codes for specific lobular types. 2008
    		20081108 CS Extension--Pancreas: How is this field coded for a head of pancreas primary with involvement of the inferior vena cava?

    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.Assign CS extension code 54 [Blood vessel(s) major]. The inferior vena cava is one of the major blood vessels.

    The inferior vena cava is located just behind the head of the pancreas. The hepatic artery, the superior mesenteric vessels and the portal vein are nearby.

    Reportability/Date of diagnosis--Liver: Does the final diagnosis of a scan have higher priority than the findings in the discussion in the body of the report? See Discussion.

    A patient with liver cancer becomes transplant eligible when the tumor is 2 cm in size. Frequently, liver tumors will be watched (no biopsy) for months until they meet the 2 cm size criteria. In the meantime, multiple scans will describe the tumor using variations of ambiguous terms that drift in and out of reportablility. One day the tumor is labeled "presumed hepatocellular carcinoma." Weeks later it is back to "worrisome for hepatoma." A single scan will use different terms in different sections of the report.

    Example case: Abdominal CT reveals a 1 cm liver lesion. Per the discussion portion of the scan, the lesion is consistent with hepatocellular carcinoma. Per final diagnosis: 1 cm liver lesion, possibly hepatocellular carcinoma. Is this report diagnostic of cancer? Would the date of this report be the date of diagnosis? (Patient did receive a liver transplant for hepatocellular carcinoma months later.)

    When a reportable ambiguous term is used in one part of a report or the medical record and a non-reportable ambiguous term is used in another part of the report or the medical record, accept the reportable term and accession the case.

    The example above is reportable. "Consistent with" is a reportable ambiguous term. Accept "consistent with" over the non-reportable term "possibly."

    The date of this report would be the date of diagnosis if this is the earliest report using reportable terminology.

    		20081067 CS Extension--Lymphoma: When does the coding change take effect that is referred to in SEER edit IF195, that states localized lymphoma in primary sites C024, C090-099, C111, C142, C172, C181, and C379 must be coded to CS extension 10, and cannot be coded to extension 11? See Discussion. CS version 1.04 does have a new note 1 in the lymphoma scheme that appears this coding change. In the past, we used code 11 with these sites for localized lymphoma and SINQ 20061088 confirms this line of thinking.

    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.

    This change was made with the release of CS version 01.04.00 on October 31, 2007. The rules went into effect for cases diagnosed January 1, 2008 and later. A note was added to SINQ 20061088 stating that the answer pertains to cases diagnosed prior to January 1, 2008.

    		20081083 Multiple primaries--Lymphoma: Is mediastinal large B-cell lymphoma followed by classical Hodgkin lymphoma reportable as one or two primaries? See Discussion. Diagnosed 06/06/2006 with mediastinal large B-cell lymphoma, 9679/36. On 05/10/2007, another mediastinal lymph node biopsy done and the diagnosis was recurrent malignant lymphoma, classical Hodgkin's. A Hematopatholgy Consultant states, "it appears likely that the preceding mediastinal diffuse large B-cell lymphoma and the current classical Hodgkin's lymphoma are clonally related and represent different manifestations of the same entity. One might also place this in the spectrum of 'mediastinal gray zone lymphoma' described by Dr. Jaffee and colleagues."

    For cases diagnosed prior to 1/1/2010:Report this case as two primaries. Report non-Hodgkin lymphoma followed by Hodgkin lymphoma as separate primaries.

    According to the Table of Single and Subsequent Primaries for Hematologic Malignancies, mediastinal large B-cell lymphoma and Hodgkin disease are "D" - Different disease processes.

    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.
