20100015 | Type of Multiple Tumors/Multiplicity Counter--Breast. Are the data items "Type of Multiple Tumors Reported as One Primary" and "Multiplicity Counter" related? How should they be coded for breast cases in which there are multiple measured invasive tumors, plus DCIS which is not measured nor stated whether it is separate from the invasive tumors? See Discussion.
|
For example, path report states only "multifocal invasive ductal carcinoma, 1.5 cm and 0.8 cm, and low-grade DCIS." The Multiplicity Counter instructions tell us to ignore/do not count foci that are not measured. Should we interpret this to mean, count only the two invasive foci and ignore the DCIS? Should Type of Multiple Tumors then be coded 30 or 40, because only the invasive tumors are coded in Multiplicity Counter? | Code Type of Multiple Tumors 30 [in situ and invasive]. The code in Type of Multiple Tumors may or may not reflect the tumors that were counted in Multiplicity Counter. For this case, it is correct to code 02 in multiplicity counter. | 2010 |

20100104 | Grade--Heme & Lymphoid Neoplasms: Is the phrase "aberrant T-cell expression" enough to code the grade field to T-cell when the final diagnosis on the pathology report is "AML with aberrant T-cell antigen expression"? | Yes. Code grade to 5 [T-cell]. The T cell receptor, or TCR, is a molecule found on the surface of T lymphocytes (or T cells). | 2010 | |

20100071 | Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a patient diagnosed in February 2010 with a plasmacytoma of the frontal skull followed by a diagnosis of smoldering myeloma by bone marrow biopsy? See Discussion. | The patient had a diagnosis of solitary plasmacytoma of the right frontal skull in 2/2010 that was totally resected (the cranial specimen final diagnosis was plasmacytoma). The patient received radiation. While undergoing radiation, the patient was seen by a medical oncologist who did a bone marrow biopsy that revealed 10-15% plasma cells, and was called smoldering myeloma. Watchful waiting was recommended. In 8/2010, the patient had multiple lytic lesions and began systemic treatment.
Per rule M15 and the Multiple primary calculator, 9731/3 [plasmacytoma] and 9732/3 [smoldering myeloma] is accessioned as two primaries. When the manual states, "Use the Hematopoietic Database to determine the primary site and histology when PH1-PH29 do not apply," does this mean to use the calculator not the database itself? By the old rules this was one primary. Did this change for cases diagnosed 1/1/10 and later? Which M rule is the correct rule to apply? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
The smoldering myeloma is a second primary per Rule M10. Accession as multiple primaries because this case was originally diagnosed as a chronic neoplasm (plasmacytoma)phase and there was a second diagnosis of an acute neoplasm (multiple myeloma) more than 21 days after chronic diagnosis. See note 1 which indicates, "This is a change from previous rules." Note that the MP rules and the MP calculator in the Heme DB agree.
When the rules tell you to go to the DB to determine the histology and primary site, you use the DB information. (Don't forget to check the Abstractor Notes). The multiple primaries calculator is used to determine the number of primaries to abstract. Always use the M rules before using the MP calculator.

20100061 | MP/H Rules/Histology: The 2010 SEER Manual has omitted some useful information in the Histologic Type ICD-O-3 section, specifically the statement of "Do not revise or update the histology code based on subsequent recurrence(s)". Will this statement be added to the revisions of the MPH rules? See Discussion. | Example: A 2005 diagnosis of left breast lobular carcinoma [8520/3], followed by a 2009 diagnosis of left breast ductal carcinoma [8500/3]. Rule M10 states this is a single primary, but there is no information in the Histology rules (Multiple Tumors Abstracted as a Single Primary) that the original histology should be retained, thus a person could potentially use these rules to change the original histology to 8522/3 [duct and lobular carcinoma] per rule H28. | We will reinstate the instruction not to change the histology code based on recurrence in future versions of the histology coding instructions. However, this instruction may not be applicable to all anatomic sites. It will be reinstated on a site-by-site basis. You may also refer to the instructions on Page 7 of the 2010 SEER Manual under the heading "Changing Information on the Abstract." | 2010 |

20100053 | Primary site--Heme & Lymphoid Neoplasms: How is primary site coded for a myeloid sarcoma (granulocytic sarcoma) arising in the chest wall in a patient that has a negative bone marrow biopsy? See Discussion. | Patient was diagnosed with Myeloid Sarcoma (granulocytic sarcoma) by chest wall biopsy. This is an extramedullary manifestation of acute leukemia and is not in the bone marrow (bone marrow is negative).
How should primary site be coded? The Heme DB states that almost any part of the body can be involved. It also states to not code primary site to C421. In this case the only involvement is the chest wall [C493]. However, use of the primary site code C493 triggers an edit error questioning this site/histology combination. If the primary site is coded to C421 [bone marrow], there is no edit error. Please explain the site code and rationale. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Unless there are scans showing involvement of a lymph node or tissue other than the chest wall, the histology should be coded myeloid sarcoma [9930/3] and the primary site to C493 [soft tissue of chest wall]. Per Rule PH 30, use the Heme DB to determine primary site and histology when rules PH1-PH29 to not apply. Override the edit.
Per the Abstractor Notes section in Heme DB, for myeloid sarcoma [9930/3] the most frequently affected sites are skin, lymph nodes, gastrointestinal tract, soft tissue, and testis.

20100070 | Histology--Heme & Lymphoid Neoplasms: How is this field coded for a follicular lymphoma, grade 2 of 3, predominantly nodular? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code histology to 9691/3 [Follicular lymphoma, grade 2]. Nodular lymphoma is an obsolete term once used to describe follicular lymphoma. (See Appendix A, Table A3)

20100078 | MP/H Rules/Histology--Lung: How is histology coded for a diagnosis of squamous carcinoma and large cell undifferentiated neuroendocrine carcinoma? | For cases diagnosed 2007 or later, apply rule H7 and code the numerically higher ICD-O-3 code, 8070/3 [Squamous cell carcinoma]. See Chart 1, the histology tree in lung equivalent terms. Large cell neuroendocrine carcinoma is histology code 8013/3. The other histology is squamous carcinoma, 8070/3. 8070/3 is higher numerically than 8013/3. | 2010 | |

20100011 | Reportability: Should a benign gangliocytic paraganglioma [8683/0] be a reportable (malignant) tumor based on the presence of lymph node metastases? See Discussion. |
"Resection, periampullary duodenum: Gangliocytic paraganglioma, with metastasis to one large periduodunal lymph node. Six other small lymph nodes negative. COMMENT: The primary tumor in the duodenum is made up mainly endocrine cell component. This component appears to have metastasized to a periduodenal lymph node." |
This neoplasm is reportable because it is malignant as proven by the lymph node metastases. Code the behavior as malignant (/3) when there are lymph node metastases. |

20100024 | Histology: How is this field coded for a perivascular epithelioid cell neoplasm (PEComa) of uncertain malignant potential that is malignant based on the presence of metastases? See Discussion. |
In 11/2006 the patient had surgery for a 6cm mass in the RUQ arising in the falciform ligament. The pathologic final diagnosis was: Perivascular epithelioid cell neoplasm (PEComa) of uncertain malignant potential. In 10/2009 a liver biopsy showed metastatic perivascular epithelioid cell neoplasm. |
Assign histology code 8005/3 [malignant clear cell tumor]. According to our expert pathology consultant, this is the best histology code available at this time for the occasional tumor which is designated as malignant. The appearance of metastatic disease clearly defines this case as malignant. |

20100103 | Reportability--Corpus uteri: Is gestational trophoblastic neoplasia reportable if there is no mention of metastasis but the patient has been treated with chemotherapy? See Discussion. | Per SINQ 20021106, for tumors diagnosed prior to 2007, a clinical diagnosis of metastatic gestational trophoblastic disease was to be coded to histology 9100/3 [Choriocarcinoma]. "Gestational trophoblastic neoplasia includes the diagnosis of choriocarcinoma." |
Do not report gestational trophoblastic neoplasia unless stated to be malignant. | 2010 |
