Reportability--Heme & Lymphoid Neoplasms: Is reactive plasmacytosis a reportable diagnosis that is equivalent to plasmacytoma?

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

Reactive plasmacytosis is not reportable unless there is another indication of a reportable neoplastic disease. Reactive plasmacytosis is "a well known pathological process described as occurring in a variety of situations including infections, autoimmune disease, diabetes mellitus, sideropenia, liver cirrhosis and neoplastic conditions including leukemia. This process, by definition, is assumed to be a reaction of the immune system to an unknown or poorly defined stimulus." Based on this definition, reactive plasmacytosis is not the same as a plasmacytoma, although it may indicate the presence of a neoplastic process, such as leukemia.

Reportability--Heme & Lymphoid Neoplasms: Is reactive thrombocytosis reportable? See Discussion.

The doctor's impression: "Thrombocytosis, mild without other obvious hematologic difficulty. I would be most suspicious for early iron deficiency related to her prior menometrorrhagia. Would limit initial evaluation to iron studies, review of peripheral smear, and hepatic profile."

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

Reactive thrombocytosis is not reportable and is not an alternative name for essential thrombocythemia [9962/3].

Only the following are listed as alternate names for essential thrombocythemia in the Heme DB:

  • Essential hemorrhagic thrombocythemia

  • Essential thrombocytosis

  • ET

  • Hemorrhagic thrombocythemia

  • Idiopathic hemorrhagic thrombocythemia

  • Idiopathic thrombocythemia

  • Idiopathic thrombocytosis

  • Primary thrombocythemia

  • Primary thrombocytosis

  • Thrombocythemia vera

    Reportability--Heme & Lymphoid Neoplasms: Is the diagnosis of large granular lymphocyte syndrome or large granular lymphocyte disorder a reportable synonym for T-cell large granular lymphocytic leukemia? See Discussion.

    The physician consult in this case further specifies that the large granular lymphocyte disorder represents an autoimmune disease of autoimmune T-cell mediated mechanism. Is this a reportable diagnosis?

    Report large granular lymphocyte disorder (9831/3). Alternate names for T-cell large granular lymphocytic leukemia (9831/3) listed in the Hematopoietic and Lymphoid Neoplasms Database include but are not limited to Chronic large granular lymphocyte lymphoproliferative disorder, large granular lymphocytosis, NOS, and T-cell large granular lymphocytosis.

    Reportability--Heme & Lymphoid Neoplasms: Is the pathologic final diagnosis of "follicular lymphoma, WHO grade 1-2, findings may represent in situ follicular lymphoma" reportable if the clinician also states this may be an "in situ follicular lymphoma"? See Discussion.

    2/16/11 mesentery biopsy showed "follicular lymphoma, WHO grade 1-2, findings may represent an "in situ" follicular lymphoma."

    3/7/11 clinician note stated, "nodularity of the mesentery which upon biopsy may be in situ follicular lymphoma. No treatment is necessary. This is not a proven malignancy. It may evolve into one. Plan 6 month follow-up and CT scans.

    Do the notes from the oncologist and pathologist stating that this "may be" or "may represent" an in situ lymphoma make this case non-reportable?

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

    This case should not be accessioned. In situ lymphoma is not reportable for any of the standard setters (CoC, NPCR, or SEER). In the Case Reportability Instructions, the NOTE under Rule 3 states, "Do report in situ (/2) lymphomas."

    Reportability--Heme & Lymphoid Neoplasms: Is the term "thrombocytopenia" equivalent to the term "refractory thrombocytopenia" and should be a subsequent primary if it follows a treated diagnosis of pancreatic cancer?

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

    Thrombocytopenia NOS is not a reportable diagnosis per Appendix F. Thrombocytopenia and Refractory Thrombocytopenia are not the same disease.

    Thrombocytopenia is caused by a decreased number of platelets in the blood. Non-malignant causes include disseminated intravascular coagulation (DIC), drug-induced non-immune thrombocytopenia, drug-induced immune thrombocytopenia, hypersplenism, immune thrombocytopenic purpura (ITP), thrombotic thrombocytopenic purpura, and infections of the bone marrow.

    Reportability--Heme & Lymphoid Neoplasms: Is this a reportable case and if so what codes would be used for the primary site and histology?

    Lymph node flow cytometry and bone marrow biopsy revealed involvement by a low-grade B-cell lymphoproliferative disorder. Medical oncologist states monoclonal gammopathy, question marginal zone B cell lymphoma versus lymphoplasmacytic lymphoma/lymphoproliferative disorder.

    Based on the information provided, this case is not reportable. Low grade B-cell lymphoproliferative disorder is not reportable, nor is monoclonal gammopathy. There is no definitive diagnosis for marginal zone or lymphoplasmacytic lymphoma. The terminology used includes "question" and "versus" which are not acceptable ambiguous terms for reportability. If possible, follow up with the physician regarding the definitive diagnosis.

    Reportability--Heme & Lymphoid Neoplasms: Should a 2011 diagnosis of Langerhans cell histiocytosis be accessioned as a reportable case if the patient had a disease free interval between the 2011 diagnosis and when the patient was initially diagnosed with Langerhans cell histiocytosis prior to 2010? See Discussion.

    The patient was diagnosed with Langerhans cell histiocytosis as a child when the disease was not reportable [9751/1]. The patient was disease free until a recurrence in 2011. Langerhans cell histiocytosis is reportable if diagnosed 1/1/2010 and later [9751/3]. The Heme Manual states this is a single primary, but the behavior has changed from borderline to malignant since the initial diagnosis.

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

    Do not accession the 2011 diagnosis of Langerhans cell histiocytosis. In the Abstractor Notes section of the Heme DB is indicates this is reportable for cases diagnosed 2010 and later. However, this patient was initially diagnosed prior to 2010 when it was not a reportable disease process.

    The histology code for Langerhans cell histiocytosis has not changed over time. The histology code for cases of Langerhans cell histiocytosis diagnosed prior to 2010 was also 9751 per the ICD-O-3. The only change since 2010 was in the behavior code for this disease. It changed from borderline [/1] to malignant [/3]. The current disease represents a recurrence of the previous Langerhans cell histiocytosis. Per the Multiple Primary rules, Rule M2, a single histology is a single primary. The original diagnosis was made before the disease was reportable; do not report the disease recurrence or progression as a new primary.

    Reportability--Heme & Lymphoid Neoplasms: The term indolent systemic mastocytosis is listed in the 2018 ICD-O-3 Histology Update table with borderline behavior (9741/1). However, smoldering systemic mastocytosis is listed in the Hematopoietic and Lymphoid Database (Heme DB) as an alternate name for histology 9741/3. Are smoldering systemic mastocytosis and indolent systemic mastocytosis synonymous? If so, should smoldering systemic mastocytosis also be removed from the Heme DB alternate names listing? See Discussion.

    In addition to the issue mentioned above, there is a SINQ answer that conflicts with the 2018 ICD-O-3 Histology Update table. SINQ 20130134 indicates indolent systemic mastocytosis is reportable for cases diagnosed 2010 and forward. There is no date restriction indicating the SINQ note applies only for cases diagnosed 2010-2017. Since indolent systemic mastocytosis was changed to borderline (9741/1) for diagnosis year 2018+, should the diagnosis year range be updated for this SINQ answer?

    Smoldering systemic mastocytosis is reportable, 9741/3. Indolent systemic mastocytosis is not reportable as of cases diagnosed 2018, 9741/1.

    Smoldering systemic mastocytosis and indolent systemic mastocytosis are not synonymous. Smoldering differs from indolent based on diagnostic criteria and burden of disease; indolent is low whereas smoldering is high burden of disease that can progress to aggressive systemic mastocytosis or mast cell leukemia.

    We will update SINQ 20130134.

    Reportability--Heme and Lympoid Neoplasms--Polycythemia vera: Is secondary polycythemia vera reportable? See Discussion.

    A physician stated the patient likely had secondary polycythemia vera due to cardiac and pulmonary conditions but that a polycythemia vera could not be ruled out. A JAK2 was ordered that was positive for JAK2 V617F mutation. The patient was treated with hydrea.

    According to SEER SINQ 20120049, secondary polycythemia vera is not reportable. However, in this case, the patient was positive for JAK2 V617F mutation. Therefore, is this reportable? We looked for guidance in the Hematopoietic and Lymphoid Neoplasms Database and found it confusing that secondary polycythemia vera was not mentioned or discussed under polycythemia vera in the database. The only thing we could find was secondary polycythemia NOS that was discussed under polycythemia.

    Abstract as a new primary for polycythemia vera, 9950/3.

    JAK2 is commonly used to assess suspected polycythemia vera and in this case, the mutation is positive for V617F.

    Based on the JAK2 results, this looks like a true polycythemia vera and not a secondary polycythemia.

    Reportability--Is "intraductal papillary mucinous neoplasm with low grade dysplasia" (also called IPMN adenoma) reportable? See Discussion.

    According to the ICD-O-3, the histology for IPMN adenoma is 8453/0 is non-reportable. However, per SINQ 20021099, this is reportable.

    Intraductal papillary mucinous neoplasm (IPMN) of the pancreas with low grade dysplasia, also referred to as IPMN adenoma, is not reportable.

    IPMN of the pancreas is reportable when stated as "IPMN with high-grade dysplasia," or "IPMN with an associated invasive carcinoma," or  "IPMN with an associated in situ carcinoma."

    The case in SINQ 20021099 is stated to have "multifocal high grade dysplasia (so-called borderline tumor and carcinoma in-situ)" and is reportable because there is an explicit statement of carcinoma in situ, not because of the reference to the presence of high grade dysplasia. It is coded 8453/2 [Intraductal papillary-mucinous carcinoma, non-invasive].
