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."

20081139 Date Multiple Tumors--Prostate: For a prostate biopsy done 10/20/08, both lobes involved with tumor, unknown how many tumors, what would be coded in date of multiple tumors? In this case, code the date of the biopsy in Date of Multiple Tumors [10202008]. When the number of tumors is unknown, code the date of diagnosis as the Date of Multiple Tumors. This is the date on which it was determined that there were an unknown number of tumors. This instruction will be added to next edition of the MP/H manual. 2008
20081120 MP/H Rules--Sarcoma: How many primaries should be abstracted for chondrosarcoma of right toe in 2002, of right lower leg in 2006 and right tibia in 2007? See Discussion. A patient had a myxoid chondrosarcoma of the right toe in 2002. This was amputated and staged as T2 - high grade. Patient had a recurrence in the lower right leg in 2006. At this time he had a below knee amputation. The tumor in 2006 was stated to be similar histologically to the 2002 tumor with pathologic comparison done. Then in 2007 the patient presents with pain in right knee and stump. CT says compatible with recurrent disease, but no copies of path sent. Patient then had an above knee amputation, with diagnosis of clinically recurrent chondrosarcoma of tibia. How many primaries should be abstracted? Is 2007 diagnosis a new primary?

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.

20081014 Surgery of Primary Site--Prostate: How is transurethral microwave treatment coded for prostate primaries?

Assign code 16 [Hyperthermia]. See the SEER Note on page C-747 of the 2007 SEER Manual:

Code Transurethral Microwave Thermotherapy (TUMT) as 16.

Multiple primaries/Histology--Lymphoma: How many primaries should be abstracted and how should the histology field(s) be coded in this situation?

How would the bone marrow involvement by only NHL be handled? Composite lymphoma (9596) as defined by SEER and ICD-O is NHL and HD in one node which fits the final impression on the removed cervical node. See Discussion.

 Patient presented with cervical, supraclavicular & superior mediastinal lymphadenopathy. A cervical node was excised for pathological review. The final impression on that node was Composite lymphoma characterized by (1) Nodular Lymphocyte Predominant Hodgkin Lymphoma [HD] (2) CLL/SLL [NHL]. Then, a bone marrow aspirate/bx was performed revealing CLL/SLL [NHL].

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.

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.

Reportability--Brain and CNS: Is hygroma reportable? See Discussion.

Benign brain guidelines indicate that named tumors that have been assigned an ICD-O-3 code are reportable. However, per I&R: "Most cystic hygromas (9173/0) are fetal malformations and occur in patients less than two years old. If this patient was an adult, they are primarily treated with surgery. Hygroma (used in a general sense) is a response to trauma (i.e., subdural hematoma) and as such, is not a "new growth" and would not be reportable either as a cyst or as a neoplasm. Unless the patient had some sort of operation, I'd hesitate to include the case as a reportable benign tumor."

How is the cancer registrar to distinguish between reportable and non-reportable hygromas? Example: Brain MRI showed diffuse cerebral volume loss and incidental bilateral frontal subdural hygromas (histology code 9173/0).

Reference: I&R 14825

Hygromas are not reportable. This instruction will be added to the next revision of the benign brain rules.

According to an expert in the field, hygromas are not neoplastic. Hygromas are cystic dilations of a localized subarachnoid or subdural accumulation of clear fluid related to an excess accumulation of CSF, typically related to an old hemorrhage that somehow prevents reabsorption of CSF.

20081036 MP/H Rules--Breast: Is inflammatory breast cancer always one primary per lifetime? Or is a subsequent inflammatory breast cancer a second primary if diagnosed more than five years later? For cases diagnosed 2007 or later, a diagnosis of inflammatory breast cancer more than five years after a previous diagnosis of inflammatory breast cancer is a separate (new) primary. See rule M5 in the Breast Multiple Primary Rules. 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

MP/H Rules/Histology--Breast: If an in situ carcinoma diagnosed in 2007 demonstrates comedo necrosis, should the histology be coded to comedocarcinoma in situ? See Discussion.

According to the new MP/H rules, we code descriptive features. There is no coding guidance or reference to "necrosis" within the breast MP/H rules. Based on SEER SINQ 20021002, the "comedo necrosis" would not be coded at all for pre-2007 cases. Does this still hold true for cases diagnosed after January 1, 2007?

For cases diagnosed 2007 or later, comedo necrosis is not synonymous with comedocarcinoma. If no further information is available for this case, code as carcinoma in situ.
