20081046 MP/H Rules--Corpus uteri: How is histology coded for an endometrial tumor described as an "endometrioid adenocarcinoma with prominent squamous metaplasia"?

For cases diagnosed 2007 or later:

Endometrioid adenocarcinoma with squamous metaplasia is coded 8570 [Adenocarcinoma with squamous metaplasia]. This falls under the Histology Coding Rules for Other Sites, rule H17. The code for Endometroid adenocarcinoma is 8380. The code for Adenocarcinoma with squamous metaplasia is 8570. The histology with the numerically higher ICD-O-3 code is Adenocarcinoma with squamous metaplasia -- 8570.

20081062 MP/H Rules/Date of Diagnosis/Behavior--Brain and CNS: How many primaries would be reported when a December 2004 MRI shows a pineal region mass with the major differential consideration being pineocytoma; a November 2007 MRI that shows the mass has almost tripled in size; and the December 2007 resection final diagnosis is consistent with pineoblastoma? How would diagnosis date[s] and behavior code[s] be coded? See Discussion.

Dec. 2004 MRI of brain: Pineal region mass. The major differential consideration given patient's gender, age group, and imaging characteristics is pineocytoma. The differential includes pineoblastoma or germ cell line tumor. These are felt less likely.

Nov. 2005 MRI brain: stable exam since last MRI. No change in size.

Nov. 2007 MRI studies: pineal mass has almost tripled in size.

Dec. 2007 Surgical resection of pineal tumor: High grade (WHO Grade IV) pineal parenchymal neoplasm consistent with pineoblastoma.

For cases diagnosed 2007 or later:

Abstract as separate primaries:

  • 12/2004 pineocytoma (9361/1)

  • 12/2007 pineoblastoma (9362/3)

    • Complete two abstracts when a previously diagnosed non-malignant tumor transforms or progresses to a malignancy. Refer to the CDC/NPCR guidelines for Data Collection of Primary Central Nervous System Tumors, 2004. Malignant transformation is discussed on page 50.

    		20081136 CS Extension--Corpus uteri: Can a suspicious cytology be used to code extension? See Discussion.

    Endometrial primary confirmed by biopsy on 10/26/06. Pelvic washing on 11/14/06 was 'suspicious for malignancy.' Resection path the same day stated the primary tumor invades the inner 1/3 of the myometrium.

    Can we use the pelvic washing cytology & code CS extension 61 or should CS extension be coded 12?

    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 extension code 61 [cancer cells in peritoneal washings] for the case described above.

    "Suspicious" is listed as a term indicating involvement. There is no exception noted for cytology reports. See page 122 of the 2007 SEER manual.

    		20081074 Primary site/Histology: Does SEER accept the site/type combination of lymph nodes (C77.0-C77.9) with the histology of either 9823 (B-cell chronic lymphocytic leukemia/small cell lymphocytic lymphoma) or 9827 (Adult T-cell leukemia/lymphoma)? See Discussion. There is a discrepancy between the SEER Site/Type table and the CS histology codes under Lymph Nodes.

    For cases diagnosed prior to 1/1/2010:These are not "impossible" site/histology edits. You can override them. However, if the lymph nodes are involved and a lymphoma histology is available, the lymphoma histology should be coded rather than leukemia histology. For example, assign histology code 9670 (Malignant lymphoma, small B lymphocytic, NOS) instead of 9823 (B-cell chronic lymphocytic leukemia/small cell lymphocytic lymphoma) if the disease is identified in the lymph nodes.

    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.

    		20081032 Radiation Therapy--Breast: If hospital records indicate that a mammocyte intracavitary radiation therapy device was placed in the breast, but there is no follow-up documentation of radiation actually being given, should we code radiation 2 (implants) or 8 (recommended, unknown if given)? Assign code 8 [recommended, unknown if administered]. Check this case periodically, and others coded 8. Update if further information becomes available. 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.

    		20081034 Race, Ethnicity/Spanish Surname or Origin: Which Spanish Surname List (from 1980 census or 1990 census) would SEER prefer us to use to code 7 in Spanish Surname or Origin? See Discussion. In the SEER coding manual, it refers to "a list of Hispanic/Spanish names" (5e), but does not specify which one to use. Again, for the Computed Ethnicity field, which Spanish Surname List does SEER prefer us to use? Determine which list is better suited for your geographic area. If the 1990 list is used, determine the probability cut-off that seems most reasonable for your geographic area. 2008
    		20081029 Multiple Primaries--Brain and CNS: Multiple cavernous hemangiomas diagnosed in 1995 are treated with radiation and steroids in 1996. A 1999 MRI states there is no interval change with the lesions in selected location since 1995. How many new primaries should be reported if a 2006 MRI states there are additional cavernous hemangiomas in other parts of the brain? See Discussion.

    7-03-97 PE: Past history significant for cavernous hemangiomas. Has had radiation and was on high-dose steroids in early 1996. Patient reports subsequent MRI done and neurologist gave "clean bill of health."

    1-26-99 MRI BRAIN. Clinical information: history of intracranial cavernous hemangiomas. Comparison with prior brain MRI in 12/15/95. IMP: Upper medullary, right parieto-occipital, left frontal cavernous hemangiomas without interval change in size as compared to 12/15/95.

    1-25-06 MRI BRAIN. Clinical info: history of prior radiation for cavernous angiomas. Comparison made with prior exam on 1/26/99. Impression: Multiple, variable sized cavernous angiomas within medulla, pontomedullary junction, midbrain, & cerebral hemispheres. Dominant lesion centered within posterior pontomedullary junction. FINDINGS: 8mm lesion in posterior pontomedullary junction. 2mm lesion within right paracentral portion of medulla. Several less than 5mm lesions noted within brain stem bilateral. Two, less than 1-2mm, areas within right inferior aspect of right and left cerebellar hemispheres. 1cm lesion centered within white matter within right posterior parietal/occipital region. Several small, less than 1-2mm, lesion within surrounding white matter. 3rd dominant lesion within left frontal lobe equal 6mm. Several 1-2mm foci of susceptibility artifact within subcortical white matter of high right and left cerebral hemispheres consistent with small cavernous angiomas.

    Benign and borderline brain and CNS tumors diagnosed January 1, 2004 and later are reportable. Multiple tumors in different brain and CNS sites are separate primaries. Different sites are those with ICD-O-3 topography codes that differ at the first, second, third or fourth character.

    There are four reportable primaries in the scenario described above.

  • Brain stem, C717 (medulla, pontomedullary junction, midbrain)

  • Cerebrum, C710 (right cerebral hemisphere)

  • Cerebrum, C710 (left cerebral hemisphere)

  • Parietal/Occipital region, C718

    		20081096 Computed Ethnicity: Should the Name--Alias field be used when generating Computed Ethnicity? No, "Alias" is not used and should not be used to generate Computed Ethnicity. Computed Ethnicity records the ethnicity based on last name and/or maiden name using a computer algorithm. Alias is not part of the algorithm. 2008
    		20081116 CS Extension--Brain and CNS: How is this field coded for a malignant brain tumor that presents as a lesion with significant pressure on the left frontal ventricle and dilation of the right ventricles? See Discussion. CS Extension code 30 includes tumor that invades or encroaches upon the ventricular system. Does significant pressure mean the same thing as encroach?

    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 assign extension code 30 in this case unless there is evidence elsewhere of ventricular system involvement.

    "Significant pressure" is not synonymous with encroachment or involvement. See the list of ambiguous terms for CS staging on page 121 of the 2007 SEER manual.
