MP/H Rules/Multiple primaries--Urinary: Are diagnoses in bladder, ureter, renal pelvis, and other urinary made prior to 2007 used in determining multiple primaries? See Discussion.

Per the General Information for MPH, Rule #3, the rules are effective for cases diagnosed January 1, 2007 and after. Do not use these rules to abstract cases diagnosed prior to January 1, 2007.

Example: Is a 2006 diagnosis of a renal pelvis primary with the histology 8130/3 and a 2007 diagnosis of a bladder primary with histology 8130/3 "multiple tumors" or is the bladder tumor a new primary because it is a single tumor at the time of diagnosis in 2007?

For cases diagnosed 2007 or later:

Use the 2007 MP/H rules for urinary sites to assess tumors diagnosed in 2007 or later.

For the example above, use the 2007 rules to determine whether or not the bladder tumor diagnosed in 2007 is a new primary. Use the Multiple Tumors module when comparing a 2007 or later diagnosis to an earlier diagnosis. Start with rule M3. Stop at rule M8. The 2007 bladder urothelial tumor is not a new primary since there is an existing 2006 renal pelvis urothelial primary.

20091117 MP/H Rules/Histology--Breast: How is histology to be coded for a breast primary described as "tubular carcinoma (well differentiated invasive ductal carcinoma)"? See Discussion.

How are terms that are modified by parentheses to be interpreted? Do terms in parentheses modify the stated diagnosis and thus have priority over the stated diagnosis? Or would rule H17 apply and histology would be coded as duct and other carcinoma? For this case, the wording of the diagnosis and use of parentheses seem to indicate that tubular is a type of ductal carcinoma. Tubular is not listed as a specific duct carcinoma in the MP/H rules histology tables for breast.

For cases diagnosed 2007 or later, code the histology as tubular carcinoma [8211/3]. This is not a case of tubular AND infiltrating duct. The histology is stated to be tubular. Tubular is not a specific type of duct carcinoma. 2009
20091114 MP/H Rules/Multiple primaries--Breast: Would a left chest wall mass excision stated to be ductal carcinoma consistent with a breast primary and, "compatible with either local recurrence or potentially a metastasis" be a new primary per the MP/H rules? See Discussion. Patient underwent mastectomy in 1986 for infiltrating ductal carcinoma of left breast. Excision of left chest wall mass in March 2009 showed ductal carcinoma consistent with breast primary. The pathology report COMMENT stated it would be compatible with either local recurrence or a metastasis. The patient's primary breast carcinoma material is not available for direct comparison and the MP/H rules instruct us to ignore metastasis. For cases diagnosed 2007 or later, the MP/H rules do not apply to metastasis. If there is no further information available for this case, the MP/H rules do not apply to the 2009 diagnosis. 2009
20091077 CS Site Specific Factor--Head & Neck: Can SSF 1-6 be coded using clinical information only, or does the source of information for lymph nodes need to be pathological?

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.CS Site Specific Factors 1 through 6 for head and neck sites may be coded using either clinical or pathologic information.

Reportability--Kidney: Is the donor or the recipient the reportable patient when a cyst removed from a pre-transplanted kidney is determined to be cancerous? See Discussion.

A patient received a kidney from her son. The son's kidney had a cyst which was removed prior to the transplant and later determined to be renal cell ca. Who do we report, the donor or the recipient?

The renal cell carcinoma should be reported for the donor. The cyst that was determined to be carcinoma was removed before the kidney was transplanted.

20091018 MP/H Rules/Multiple Primaries/CS Extension: How many primaries are to be accessioned when tumors are present bilaterally in the pleura and fallopian tubes? See Discussion.

For both pleura and fallopian tube, the MP/H rules indicate that bilateral involvement of these sites should be coded as multiple primaries. However, both of these sites have CS extension codes that classify the contralateral disease as regional extension.

Is a case described as a left sided pleural mesothelioma that has right sided pleural disease coded as one or two primaries? How is CS coded?

For cases diagnosed 2007 or later:

For a pleural or fallopian tube primary, if there is tumor(s) on the left and separate tumor(s) on the right and neither is stated to be metastatic from the other, abstract as multiple primaries according to rule M8 for other sites. If both sides are involved, but there is only one tumor, rule M2 for other sites applies and this is a single primary. Code each primary separately in CS.

Race--How and when is Appendix D, Race and Nationality Descriptions from the 2000 Census and Bureau of Vital Statistics, to be used? See Discussion.

For example, if race is recorded as unknown on the facesheet of a hardcopy medical record or in the race field of an electronic medical record, how should race be coded for the following descriptions found in the history and physical or consultation reports submitted by clinicians?

1) Patient is Czechoslovakian

2) Patient is born in Czechoslovakia

3) Patient is Ethiopian

4) Patient is born in Ethiopia

5) Patient is Japanese

6) Patient is born in Japan

7) Patient is Brazilian

8) Patient is born in Brazil

Would you code these cases any differently if these descriptions were actually used in the race fields in the medical record or on a death certificate?

Code the patient's stated race when possible. Refer to Appendix D, Race and Nationality Descriptions from the 2000 Census and Bureau of Vital Statistics, for guidance.

Use the lists in Appendix D when race is not stated but other information is provided in the medical record. The cases you provide are good examples of the use of Appendix D. They would be coded the same if the descriptions were used in the medical record or death certificate race fields.

20091037 MP/H Rules/Histology--Brain: How is histology coded for a "low grade neuroglial tumor" of the fourth ventricle?

For cases diagnosed 2007 or later, assign histology code 9505/1 [Ganglioglioma, NOS].

According to our pathologist consultant, low grade neuroglial tumor of the fourth ventricle correlates best to the "rosette-forming glioneuronal tumor of the 4th ventricle" which is a new WHO entity. There is no current ICD-O-3 code for this. The best code available at this time is 9505/1.

Primary site--Esophagus: How is primary site coded for a tumor arising in a segment of the esophagus that was reconstructed using a segment of the colon? See Discussion.

A patient had a ruptured esophagus 25 years ago and had a segment of colon removed and transplanted to serve as esophagus. In 2007, the patient was diagnosed with carcinoma in a polyp by endoscopic biopsy of the transplanted 'esophagus'. What is the primary site code? Is this the same site schema to be used for Collaborative staging and surgery coding?

Code the primary site esophagus, NOS [C159]. Use the surgery codes and collaborative staging schema for esophagus. Document the unusual nature of this case in text fields.

20091019 MP/H Rules/Histology--Hematopoietic, NOS: Can a diagnosis of multiple myeloma be made if a bone marrow biopsy is negative? See Discussion. Patient with large mass nasal cavity. Biopsy shows plasmacytoma. Fine needle aspiration of the acetabulum is consistent with multiple myeloma. Skeletal survey shows multiple lytic lesions. Bone marrow biopsy is negative for myeloma. In light of negative bone marrow biopsy can this case be coded as multiple myeloma?

For cases diagnosed prior to 1/1/2010:Code this case as multiple myeloma. The fine needle aspiration of the acetabulum is a biopsy of bone marrow. According to our pathologist consultant, the positive bone marrow biopsy (acetabulum) and the multiple lytic bone lesions confirm multiple myeloma. The negative bone marrow biopsy is likely due to an insufficient sample.

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.
