Report Question ID Question Discussion Answer Year
20081095 Race, ethnicity/Spanish surname or origin: If birthplace is Brazil or Portugal, patient's last name is on the Spanish Surname list, and there is no text to further clarify ethnicity, what is the correct Spanish Ethnicity code: 0 or 7? See Discussion. See also SINQ 20081075.

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."

20081081 Reportability: If a dermatopathologist refers to an atypical fibroxanthoma as a malignant process, but the ICD-O-3 indicates it is a borderline process, is this a reportable case? See Discussion. "Final Diagnosis: Surface of ulcerated histologically malignant spindle cell neoplasm, consistent with atypical fibroxanthoma. Note: An exhaustive immunohistochemical work-up shows no melanocytic, epithelial or vascular differentiation. Atypical fibroxanthoma is a superficial form of a malignant fibrous histiocytoma." The pathologist has the final say on behavior. In this case, the pathologist states that this tumor is malignant in the final diagnosis. Therefore, this case is reportable. 2008
20081099 MPH Rules/Behavior--Breast: Would a positive right axillary node following DCIS of the right breast indicate the presence of a new primary? See Discussion. How would you abstract the information from 2007? A patient with a strong family history of breast cancer had bilateral simple mastectomies in 2000, after a suspicious mammogram. Results showed DCIS in the rt breast; no malignancy in the left breast. Now in 2007, the patient has a right axillary lymph node removed - positive for carcinoma of breast origin. Comment says, "recurrent breast carcinoma in rt axillary node from patient's known history of DCIS." Is this a new primary? Is this a diagnosis date in 2007? Is the site C509 and laterality right side?

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.

 2008
20081065 Surgery of Primary Site--Melanoma: Which surgery codes should be used for cases that have a 1 cm margin? See Discussion. For a melanoma case the surgery codes in the 30's are to be used when margins are stated to be less than 1 cm. The codes in the 40's are to be used for cases where the margins are greater than 1 cm. If the margin is exactly 1 cm, assign a surgery code from the 20-36 range. Use a code in the 40's only when the margin is greater than 1 cm. 2008

Multiple primaries--Lymphoma: Is a splenectomy done for non-Hodgkin lymphoma diffuse large B-cell of the spleen a composite histology and a single primary if a perihilar lymph node with Hodgkin lymphoma classic type is found at the time of this surgery?

For cases diagnosed prior to 1/1/2010:This is two primaries -- Non-Hodgkin lymphoma (NHL) in the spleen and Hodgkin lymphoma (HD) in a lymph node.

Composite lymphoma is NHL and HD both in a single lymph node.

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.

20081039 Diagnostic Confirmation/Histology--Hematopoietic: How are these fields coded when the final pathologic diagnosis for a bone marrow biopsy differs from the final clinical diagnosis of a hematopoietic disease? See Discussion.

Frequently, pathology reports describe hematopoietic diseases using ambiguous terms. Flow cytology and cytogenetics may be obtained. It appears that the clinician is the person who pulls all the information together for a diagnosis.

Example: Bone marrow biopsy is most compatible with chronic phase myeloproliferative disease. Path comment: Differential would include CML. Outside hematology report indicates an elevated peripheral WBC, primarily neutrophils. Flow cytometry showed 1.0 % of the white cells are myeloid blasts of abnormal phenotype, additionally finding 7.3 % basophils. Flow reported peripheral blasts at 1.2 % and peripheral basophilia. Cytogenetics report showed abnormality with trisomy of chromosomes 13 and 21. This finding is consistent with a clonal abnormality suggestive of acquired disease. Results were consistent with the absence of the t(9,22)(q34;q11) translocation or fusion product associated with CML. Subsequent clinical impression: Bone marrow evaluation most consistent with CML. Overall features most consistent with CML.

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.

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
20081044 MP/H Rules/Behavior--Melanoma of Skin: How are histology and behavior coded for a "malignant melanoma in situ with regression"? See Discussion. Per the microscopic portion of the path report, there is a zone of regression within the confines of the lesion, such that the possibility of antecedent invasive disease at the site cannot be ruled out with certainty.

For cases diagnosed 2007 or later:

Code malignant melanoma in situ with regression to 8720/2 [Melanoma in situ].

Code the histology according to the histologic type specified in the pathology report final diagnosis. Code the behavior as specified in the pathology report. Regression does not affect the coding of histology or behavior. See Melanoma Histology Coding rule H5. See 2007 SEER manual instructions for coding behavior, page 84.

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
20081109

MP/H Rules--Breast: Patient has 2 existing primaries, both of left breast and both were pure lobular carcinoma, one was diagnosed in 1994 and the other in 2005. Now a biopsy in 2008 of a supraclavicular lymph node (laterality unknown) and subcutaneous scalp tissue show metastatic DUCTAL carcinoma. Per path report, breast is the primary site. Slides from prior tumors were not reviewed. Should this be made a new primary or assumed to be metastasis from the prior breast tumors? See Discussion.

A modified radical mastectomy was performed on 10/6/94.

The 2007 MP/H rules tell us that multiple ductal and lobular tumors of breast are a single primary; however, the rules do not apply to metastatic tumors.

For cases diagnosed 2007 or later:

Abstract the 2008 diagnosis as a new primary.

Since the primary site is unproven but stated to be breast, and since the laterality is unknown, we cannot determine that the 2008 diagnosis is the same as the 2005 or the 1994 diagnosis.

Revise this case accordingly if more information becomes available.
