20130052 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded if a biopsy final diagnosis is diffuse large B-cell lymphoma but the physician's final diagnosis favored anaplastic large cell lymphoma? See Discussion. | Patient has diffuse intrathoracic, intraabdominal and pelvic lymphadenopathy. An inguinal lymph node biopsy showed diffuse large B-cell lymphoma. The physician's final diagnosis favored anaplastic large cell lymphoma, but wanted to confirm this with FISH. The patient clinically deteriorated so the FISH studies were not done. Which histology is coded? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
The histology should be coded as diffuse large B-cell lymphoma [9680/3]. The biopsy pathology report definitively diagnosed DLBCL. The physician's diagnosis cannot be used because it is an ambiguous diagnosis only, "favored anaplastic large cell lymphoma." "Favor" is an ambiguous term.

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.

20130050 | Multiple Primaries/Primary site/Histology--Heme & Lymphoid Neoplasms: How many primaries are accessioned and what is the primary site and histology for each if a 6/12/12 left shoulder mass specimen suspicious for large B-cell lymphoma is followed on 7/10/12 with three skin nodules excised from the back with a diagnosis of "composite lymphoma? See Discussion. | 6/12/12 Excisional biopsy left shoulder soft tissue mass: Suspicious for large B-cell lymphoma.
7/10/12 Excisional biopsy three skin nodules of back: "Composite lymphoma" - primary cutaneous anaplastic large cell lymphoma (CD3 pos, CD4 pos, CD30 pos, ALK neg with partial loss of CD5) and CONCURRENT cutaneous follicular center lymphoma (CD20 pos, PAX5 pos, BCL-6 pos, partially CD10 pos) and flow cytometry revealed results compatible with involvement by a lymphoproliferative disorder of T-cell lineage.
Per imaging performed, there was no involvement of lymph nodes or other organs.
Is the primary site C449 Skin, NOS and histology 9718/3 [Lymphoma, primary cutaneous anaplastic large cell] be correct? |
Code primary site to C445 [skin, back] and histology to 9718/3 [cutaneous anaplastic large cell lymphoma] .
Per Rule M6, abstract a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location. For this case, there is cutaneous follicular (follicle) center lymphoma (9597/3) and cutaneous anaplastic large cell lymphoma (9718/3).
Per Rule PH22, code the primary site to the site or origin (skin, back) and the histology to the NHL with the numerically highest ICD-O-3 code. In this case, that would be 9718/3. |

20130047 | Date of diagnosis--Heme & Lymphoid Neoplasms: What is the diagnosis date for a patient with a mild thrombocytosis diagnosed in 2008, that was subsequently treated with Anagrelide in 11/2010 following an increase in platelet count, and later in 3/2011 was found to have positive JAK2 study physician refers to as essential thrombocythemia? See Discussion. | In 2008, patient diagnosed with mild thrombocytosis. The patient opted to be followed clinically with observation. In November 2010, a CBC showed an increased platelet count to 600,000. Anagrelide was started. The patient would never agree to a bone marrow biopsy. However, in 3/2011 a JAK2 study was performed and read as positive. Following the positive Jak2 study, physician stated the diagnosis was essential thrombocytosis and started the patient on a different drug. | Code the diagnosis date to 3/2011. It wasn't until 3/2011 that the physician documented a reportable diagnosis of essential thrombocytosis [9962/3].
Mild thrombocytosis is not reportable. Therefore, the case was not reportable in 2008. Although the patient was treated in 2010, there was no documentation of a reportable diagnosis. |

20130045 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if subsequent to a bone marrow biopsy diagnosis of acute myeloid leukemia there is an oncology consult note that indicates the pathology finding is suggestive of an underlying myelodysplastic syndrome? See Discussion | 5/14/12 Bone marrow biopsy: Acute myeloid leukemia (AML).
5/21/12 Oncology consult: AML with 30-40% blasts and evidence of del(20q) and del(5q), is suggestive of an underlying myelodysplastic syndrome (MDS). Hence the patient has secondary AML.
If these are two primaries, how are the diagnosis dates coded? |
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 diagnosed on 5/14/12 as acute myeloid leukemia with myelodysplasia-related (e.g., del(5q)) changes [9895/3] per Rule M2. The patient was diagnosed with a single histology, acute myeloid leukemia with myelodysplasia-related changes per the submitted information.

20130044 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient has a biopsy diagnosis of extraosseous plasmacytoma followed fourteen days later with a diagnosis of multiple myeloma on imaging? See Discussion. | On 2/3/12 the patient was diagnosed via biopsy with an extraosseous (extramedullary) plasmacytoma filling both nasal cavities. On 2/16/12 a metastatic workup was performed and showed a lucent lesion in calvarium of Rt frontal bone. 2/17/12 radiation oncology consult states, "I believe this is most likely consistent with multiple myeloma." Subsequently, the 3/1/12 CT of the left shoulder showed a 3.6 cm lytic lesion of humeral head with cortical breakthrough consistent with metastasis or myeloma.
Per the Heme DB, extramedullary plasmacytoma can transform to multiple myeloma. Does that make this multiple primaries with the histologies coded to 9734/3 and 9732/3? |
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, multiple myeloma [9732/3] diagnosed on 2/3/12 per Rule M8. Abstract the acute neoplasm as a single primary when both a chronic and acute neoplasm are diagnosed simultaneously or within 21 days AND there is documentation of only one positive tissue biopsy.
This patient only had a tissue biopsy of the nasal cavity proving the chronic neoplasm (extraosseous plasmacytoma). The acute neoplasm (multiple myeloma) was diagnosed clinically based on the scans.

20130043 | 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.

20130042 | Reportability--Heme & Lymphoid Neoplasms: Is follicular lymphoma in situ reportable? See Discussion. | Parotid mass and intraparotid lymph node biopsy: Follicular lymphoma in situ (see note).
Note: The morphologic findings in conjunction with the results of immunohistochemical stains demonstrate focal follicular lymphoma in situ in a background of reactive follicular hyperplasia. Cytogenetic studies on the parotid mass demonstrated a normal karyotype. FISH analysis for BCL2 and BCL6 gene rearrangements has been requested and will be reported separately. |
Per the Note under Case Reportability Instructions Rule 3 in the Hematopoietic and Lymphoid Neoplasm Manual, do not report in situ [/2] lymphomas. | 2013 |
|
20130041 | Reportability--Heme & Lymphoid Neoplasms: Is a flow cytometry immunophenotyping of peripheral blood that demonstrates a chronic lymphocytic leukemia (CLL) phenotype reportable as CLL? See Discussion. | Final Diagnosis: "Peripheral blood, flow cytometry immunophenotyping: Monoclonal B-cell lymphocytosis with Chronic Lymphocytic Leukemia (CLL) phenotype; Negative for Zap 70; No abnormal T-cell population identified; CD34-positive blasts are not increased. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This is reportable. Code the histology to 9823/3 [chronic lymphocytic leukemia (CLL)]. Per Rule PH5, Note 1, CLL will always have peripheral blood involvement. Based on the provided information, this patient's peripheral blood is positive for CLL.

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.
