20130202 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported when a solitary plasmacytoma diagnosed in 2010 (T spine) is followed by another solitary plasmacytoma (L spine, different primary site) in 2013? See Discussion.

In the Heme Manual it indicates one is to abstract a second primary when a solitary plasmacytoma (chronic) is followed by a plasma cell myeloma (acute) greater than 21 days after the chronic diagnosis.

The Heme Manual does not indicate what to do when a solitary plasmacytoma diagnosed in 2010 (T spine) is followed by another solitary plasmacytoma (L spine, different primary site) in 2013. The physician specifically stated the patient does not have multiple myeloma. Is this case one or two primaries?

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. According to Rule M2, the single histology is always the single primary.

20130147 Primary site--Heme & Lymphoid Neoplasms: What the primary site for a diagnosis of Langerhans cell histiocytosis with multifocal multisystem involvement of the skin, chest, CNS and thyroid, but no evidence of involvement on a bone scan?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code the primary site to C809 [unknown].

Langerhans Cell Histiocytosis (LCH) includes three major groups:

  • Unifocal: Slowly progressing disease, involves one organ.

  • Multifocal unisystem: Involves several organs in one system.

  • Multifocal multisystem: Involves several organs in two or more systems.

    • When the disease is both multifocal and multisystem, code the primary site to unknown [C809] because there is no way to identify the origin of the neoplasm in this situation.

    		20130106 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a 2009 diagnosed Hodgkin lymphoma, nodular sclerosis type is treated and subsequently presents in 2010 with the same diagnosis? See Discussion.

    2009 diagnosis of Hodgkin lymphoma, nodular sclerosis type involved the superior mediastinal nodes, AP window nodes, bilateral axillary nodes and pulmonary nodules. The patient received chemotherapy and went into remission.

    Patient presents in 2010 with Hodgkin lymphoma, nodular sclerosing type in the superior mediastinum.

    Does timing play any part in determining if this reported as one or two primaries? There is no timing rule in the Heme Manual.

    For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

    Accession a single primary, Hodgkin lymphoma, nodular sclerosis type [9663/3] diagnosed in 2009 per Rule M2.

    Accession a single primary when there is a single histology. Note 2 for Rule M2 indicates timing is not relevant. This is disease progression or recurrence and not a new primary.

    		20130171 Reportability--Heme & Lymphoid Neoplasms: Is "plasma cell neoplasm" a synonym for multiple myeloma and is it reportable? See Discussion. Path report in the comment section states "plasma cell neoplasm such as monoclonal gammopathy of undetermined significance (MGUS)."

    For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

    Per Appendix F, plasma cell neoplasm is not a synonym for multiple myeloma. Plasma cell neoplasm is a disorder that has an abnormal number of plasma cells. MGUS is such a disorder, but it is not reportable.

    According to WHO, 'Plasma cell neoplasms' is the umbrella term that includes MGUS, plasma cell myeloma, solitary plasmacytoma of bone, immunoglobulin deposition diseases, extraosseous plasmacytoma, and osteosclerotic myeloma. Of these, only plasma cell myeloma, solitary plasmacytoma of bone, and extraosseous plasmacytoma are reportable.

    Note: This terminology was added to the 2012 Hematopoietic Manual and Database for 1/1/2012. This should not have been added. If the only diagnosis is "plasma cell neoplasm," this is not reportable. If the diagnosis is "plasma cell neoplasm c/w multiple myeloma (or another reportable disease)," then it would be a reportable disease.

    Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded if a patient with a history of chemotherapy treated "groin" lymphoma, subsequently has bone biopsies that demonstrate diffuse large B-cell lymphoma? See Discussion.

    3/2012: Patient states he has a past history of lymphoma of the "groin." A bone biopsy of the right tibia done at this facility showed diffuse large B-cell lymphoma. There was no palpable lymphadenopathy on 03/2012. There is no other information available regarding the initial diagnosis except that the patient was treated with only chemotherapy.

    For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

    Code the primary site to C774 [inguinal lymph nodes] per Rule PH18. Code the primary site to inguinal lymph nodes [C774] when the site of lymphoma is described only as an inguinal mass. Groin lymph nodes are inguinal lymph nodes.

    The diffuse large B-cell lymphoma diagnosed by right tibia biopsy is not a new primary per rule M7 because the histology of the history only case would be coded as 9590/3 [lymphoma, NOS]. No more specific histology is known for the initial diagnosis. Accession a single primary when a more specific histology [DLBCL] is diagnosed after the NOS ONLY histology when the Heme DB Multiple Primaries Calculator confirms the NOS and the more specific histology are the same primary. The right tibial involvement is not used to code the primary site because the patient had chemotherapy for this groin lymphoma prior to diagnosis of DLBCL.

    Multiple primaries/Primary site--Heme & Lymphoid Neoplasms: How many primaries are there and how should I code the primary site(s)? See discussion.

    Patient had a hemicolectomy and a salpingo-oophorectomy and was found to have diffuse large B cell lymphoma in the colon (10 cm cecal mass), 3/16 regional lymph nodes involved with lymphoma. Fallopian tube showed involvement with diffuse large B Cell lymphoma.

    Multiple primaries - Colon and fallopian tube?

    One primary - Colon? Stage IV, or lymphoma from an unknown primary? Note: There were no other lymph nodes involved.

    Use Rule M2. Abstract as a single primary when there is a single histology.

    When you have questions about how to code the primary site, start with the abstractor notes. If the answer isn't found there go to Module 7 (a specific module to help code primary site for lymphomas).

    The abstractor notes for DLBCL in this case do not provide information you can use for this case. Go to Module 7 in the PH rules.

    Use Rule PH25 Code the primary site to the organ when lymphoma is present in an organ and that organ’s regional lymph nodes. Code the primary site to colon (organ and regional lymph nodes involved). The fallopian tube is secondary involvement. As is common with lymphomas, there can be more than one organ involved. You can differentiate the primary site from the secondary site(s) because of the large colon mass with regional lymph node involvement.

    		20130084 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed on a 3/16/12 lymph node biopsy with diffuse large B-cell lymphoma which was followed on 4/18/12 with bone marrow biopsy diagnosis of follicular lymphoma? See Discussion. The patient has extensive right-sided cervical, supraclavicular, hilar, mediastinal and gastrohepatic adenopathy. A cervical node biopsy on 3/16/2012 showed DLBCL. On 04/18/2012 a bone marrow biopsy showed follicular lymphoma. The patient was started on CHOP/Rituxan after the bone marrow biopsy.

    For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

    This case is accessioned as a single primary, diffuse large B-cell lymphoma [9680/3] per Rule M12. Abstract the acute neoplasm (DLBCL) when a patient is originally diagnosed with an acute neoplasm and the neoplasm reverts to the chronic neoplasm (follicular lymphoma) AND the patient has not been treated for the acute neoplasm.

    		20130057 Histology--Heme & Lymphoid Neoplasms: How is the histology coded if the bone marrow biopsy favors lymphoplasmacytoid lymphoma and the physician states the diagnosis is lymphoplasmacytic lymphoma-Waldenstrom's macroglobulinemia? See Discussion.

    Bone marrow biopsy: Focal bone marrow involvement with B-cell lymphoproliferative disorder. Comment: This patient has 2 monoclonal proteins in serum, IgM kappa and IgG kappa clones. The marrow does have focal involvement with a small cell lymphoproliferative disorder. A lymphoplasmacytoid lymphoma is favored.

    Flow Cytometry: Bone marrow reveals a low level, kappa-bearing-B-lymphoproliferative population that has an immunophenotype compatible with mantle cell lymphoma or related small, mature non-Hodgkin lymphoproliferative disorder.

    Physician statement: lymphoplasmacytic lymphoma-Waldenstrom's macroglobulinemia.

    Per the Heme DB, the criteria to diagnosis WM is the serum paraprotein IgM. This patient's IgM was 6020 mg/dL. It was described as elevated per the physician. The physician also states the patient's IgG is elevated. According to the Heme DB, when both IgG and IgM are elevated it is indicative of LPL.

    For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

    Code the histology to 9671/3 [lymphoplasmactyic lymphoma (LPL)] per the Heme DB Abstractor Notes and Rule PH17. When IgG and IgM are elevated, code to lymphoplasmacytic lymphoma. Waldenstrom's macroglobulinemia is caused by increased lymphocytes which causes an increase in IgM. LPL has mixed abnormalities, both the lymphocytes and plasma cells are increased which results in an abnormally high IgM and IgG.

    		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.
