20130183 | Reportability--Heme & Lymphoid Neoplasms: Is a peripheral blood finding consistent with involvement by monoclonal, lambda-restricted mature B cell population with co-expression of CD5 and CD23 reportable if, immunophenotypically, the case is consistent with a chronic lymphocytic leukemia/small lymphocytic lymphoma? See Discussion. |
Peripheral blood: Final diagnosis: Leukocytosis absolute lymphocytosis monoclonal, lambda restricted B-cell population w/co-expression of CD5 and CD23 absolute increase in CD4=helper T cells. See comment. Comment: Peripheral blood findings are consistent with involvement by monoclonal, lambda-restricted mature B cell population with co-expression of CD5 and CD23, which is immunophenotypically consistent with a chronic lymphocytic leukemia/small lymphocytic lymphoma immunophenotype. However, the absolute monoclonal population is only 3.02k/ul. According to WHO criteria, in the absence of extramedullary tissue involvement, the monoclonal lymphocyte population must be greater than or equal to 5.0 k/ul. Therefore, in the absence of clinical evidence of extramedullary tissue involvement, the diagnosis is most consistent with a monoclonal B cell lymphocytosis. Review of initial analysis reveals well-defined groups of cells within lymphocyte, monocyte and granulocyte gates as defined by CD45 and sid-scatter characteristics (%'s are listed). Overall, peripheral blood findings are consistent with involvement by monoclonal, lambada-restricted B cell population with a chronic lymphocytic leukemia/small lymphocytic lymphoma immunophenotype. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. This case is reportable. Code histology to 9823/3 [CLL/SLL]. Ambiguous terminology is used to accession cases (determine reportability) because it has been used for over 30 years to do so. Any deviation from using ambiguous terminology to determine case reportability would cause the reporting of incidence counts to vary. In this case, there was a reportable, ambiguous terminology diagnosis on peripheral blood that is "consistent with" involvement by chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) immunophenotype. The ambiguous terminology "consistent with" in the flow cytometry report is acceptable to determine reportability. Given that it is the only reportable histology mentioned in the scenario, it is also used to code histology. The instruction "Do not code histology based on ambiguous terminology" is intended to be used when there is a reportable NOS histology and reportable more specific histology stated in the diagnosis. Ambiguous terminology cannot be used to report the more specific diagnosis in cases of Heme & Lymphoid neoplasms. SEER*Educate provides training on how to use the Heme Manual and DB.

20130040 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned and what rule applies when a patient has a history of chronic myeloid leukemia diagnosed in 1993 followed by a diagnosis of acute myeloid leukemia arising in chronic myelogenous leukemia, blast phase? See Discussion. |
12/1993 Bone marrow biopsy: Chronic myeloid leukemia t(9;22) (q34;q11).
09/2011 Bone marrow biopsy: Abnormal cytogenetic & FISH support persistent involvement by chronic myelogenous leukemia.
12/2011 Peripheral blood, flow cytometry: Involvement by acute myeloid leukemia arising in chronic myelogenous leukemia (CML, blast phase, 30% blasts by manual diff.).
Is the 12/2011 diagnosis a new primary? If not, why don't Rules M8-M13 apply when the Heme DB Abstractor Notes section for CML indicates that when there is a chronic, accelerated and blast phase that develops later in the course of the disease, change the histology code to the more specific diagnosis?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case should be accessioned as a multiple primary: chronic myelogenous leukemia t(9;22) (q34;q11) [9863/3] diagnosed in 1993 and acute myeloid leukemia [9861/3] diagnosed in 2011 per Rule M15.
Use the diagnosis date to determine the appropriate manual and rules to follow to determine the histologies for this case. To determine the histology of the 1993 diagnosis, use the ICD-O-2. The Heme Manual & DB will be used to determine the number of primaries and the histology of the 2011 diagnosis of AML.
Rules M8-M13 in the Heme Manual cannot be applied to this case because no transformation occurred. CML does not transform to another neoplasm.

20130097 | Reportability--Heme & Lymphoid Neoplasms: Are either heparin-induced thrombocytopenia or heparin-induced thrombocytopenia that becomes refractory thrombocytopenia reportable? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Heparin-induced thrombocytopenia is not reportable.
If the diagnosis is changed to refractory thrombocytopenia, then this case is reportable.

20130182 | Primary site--Head and Neck: How is primary site coded if a floor of mouth biopsy reveals microinvasive squamous cell carcinoma but the definitive resection of the tongue and floor of mouth unifocal lesion reveals only in situ squamous cell cancer? See Discussion. | Patient with overlapping lesion of tongue and floor of mouth. Initial biopsy of floor of mouth reveals microinvasive squamous cell cancer. Definitive resection reveals in situ squamous cell cancer. Pathology report states unifocal tumor. The tumor site on pathology report is documented as involving the tongue and floor of mouth.
Should the primary site be coded to floor of mouth because it is the site of invasive disease? Or is primary site C148 [overlapping sites of lip, oral cavity and pharynx] because invasion should not be used to determine primary site? |
Code the primary site to C068 [overlapping lesion of other and unspecified parts of the mouth]. Based on the information provided, this is a tumor described as a "book-leaf" lesion a lesion that overlaps the floor of the mouth and the underside of the tongue. | 2013 |

20130088 | Grade--Heme & Lymphoid Neoplasms: Should Grade be coded to 5 [T-cell] or 9 [cell type not determined, not stated, not applicable] for anaplastic large cell lymphoma, NOS [9714/3]? See Discussion. | Under the Grade section in the Heme DB for anaplastic large cell lymphoma, NOS it indicates the following:
"Grade - Code grade specified by pathologist. If no grade specified, code 9."
There is no reference in the Grade section that we should look at the Abstractor Notes or a specific Module in the Heme DB for additional information. However, in the Abstractor Notes section it states, "Grade is T-cell (5) unless pathologist specifically designates as a B-cell (see G2 rule)." These two statements are conflicting. Which is the correct grade? |
Assign code 5 [T-cell] for anaplastic large cell lymphoma [9714/3] unless the pathologist specifies that the histology is a B-cell disease process. See Grade rule G2, Note 2.
In the Heme DB, there is a default value in the Grade field for histologies that do not have a grade specified. However, this particular histology does not default to code 9. There was an error in the Grade section of the 2010 and 2012 versions of Heme DB that has now been corrected in the latest release. |

20130051 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when biopsies of the left and right tonsils show diffuse large B-cell lymphoma and there is no other evidence of involvement? See Discussion. | Scans are negative for lymphadenopathy and the bone marrow biopsy was benign. Radiation Oncology staged this as localized bilateral tonsil primary lymphoma. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case should be accessioned as a single primary, diffuse large B-cell lymphoma [9680/3] of bilateral tonsils. Per Rule M2, a single histology is a single primary. Note 1 for Rule M2 states bilateral involvement of lymph nodes and/or organs is still a single primary.

20130199 | MP/H Rules/Multiple primaries--Breast: Does breast Rule M10, 'Tumors that are lobular (8520) and intraductal or duct are a single primary" apply if you have two tumors in the same breast, one ductal and the other tubulolobular (8524) or are they separate primaries per Rule M12? |
Apply Rule M10 to this case. Tubulolobular is now classified as a variant of lobular. Code to lobular, NOS (8520) because Tubulolobular does not have a specific ICD-O-3 code. |

20130156 | Other therapy--Heme and Lymphoid Neoplasms: Based on the hematopoietic manual instructions, is plasmapheresis coded as treatment for Waldenstrom macroglobulinemia? See Discussion. | A patient, who was diagnosed with Waldenstrom macroglobulinemia at another facility, presented to our facility for plasmapheresis on 12/27/2012. No other treatment was given.
How is the plasmapheresis coded for treatment? |
Do not code plasmapheresis as treatment. It does not modify the neoplasm. | 2013 |
|
20130211 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported if a bone marrow shows low grade mature B cell lymphoma with IgM paraprotein - macroglobulinemia? See Discussion. | Physician note: Bone marrow shows 10% involvement with low grade lymphoma. Assessment: Low grade mature B cell lymphoma with IgM paraprotein - macroglobulinemia.
The multiple primaries calculator indicates two primaries are to be reported. However, the physician stated that Waldenstrom's macroglobulinemia is another name for this patient's lymphoma.
There were no enlarged lymph nodes seen on the CT scan. The proposed treatment for this patient is Rituxan for the macroglobulinemia. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule M2, this is a single primary because there is a single histology. The bone marrow initially showed a non-specific B-cell lymphoma. WM is a type of B-cell neoplasm. After immunophenotyping, a more specific histologic diagnosis of WM was made. In this case a single histology (WM) is diagnosed by the definitive diagnostic method (serum paraprotein demonstrating IgM), so it accessioned as a single primary.
Per PH16, code the histology to 9761/3 [Waldenstrom Macroglobulinemia (WM)] and the primary site to C420 [blood].

20130127 | Reportability--Heme & Lymphoid Neoplasms: When did smoldering myeloma become reportable? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Smoldering multiple myeloma [9732/3] has always been a reportable neoplasm. Per the Abstractor Notes section in the Heme, smoldering multiple myeloma is a variant of multiple myeloma in which the diagnostic requirements for multiple myeloma are met, but there is no organ damage. The patient is usually asymptomatic.
Smoldering myeloma is listed under the Alternate Names section in the Heme DB for multiple myeloma [9732/3] to clarify that it is a reportable neoplasm.
Report all new diagnoses of smoldering multiple myeloma now. Registries are not required to spend time and effort to find these cases if they have not been reporting them in the past. However, report earlier earlier cases if encountered today while performing casefinding or chart review procedures.
