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.

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.

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.

20130037 Histology--Heme & Lymphoid Neoplasms: How is the histology coded for a "cutaneous diffuse large B-cell lymphoma, leg type" that has been verified as a valid diagnosis with prognostic factors including age and number of lesions on the legs?

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

Code this histology to 9680/3 [diffuse large B-cell lymphoma]. Primary cutaneous DLBCL, leg type, is listed as an Alternate Name for DLBCL per the Heme DB.

Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned and what rule applies when a subsequent diagnosis of diffuse large B-cell lymphoma (95%) and follicular lymphoma, grade 3 (5%) is made following an original diagnosis of low grade CD-10 positive B-cell lymphoma, most consistent with low grade follicular lymphoma (FL) ? See Discussion.

In 2011, patient presented with a large mesenteric mass, numerous other smaller mesenteric lymph nodes, moderate retroperitoneal and extensive iliac chain adenopathy greater on right; small inguinal nodes are also present mostly on right side and splenomegaly per the CT scan. Abdominal pelvic mass needle biopsies showed low grade CD-10 positive B-cell lymphoma, most consistent with low grade follicular lymphoma (FL). The patient was treated with R-CVP with unknown response.

In June 2012, patient presented again for laparoscopy and lymph node biopsy for stated recurrence of lymphoma found on CT scan. A large mass was seen in mesentery of bowel. Abdominal mass biopsy showed diffuse large B-cell lymphoma (DLBCL). Abdominal mass #2 excisional biopsy showed diffuse large B-cell lymphoma, 95%, and follicular lymphoma grade 3, 5%. The majority of the tumor is now DLBCL.

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 diagnosed in 2011 per Rule M7. Note 4 for Rule M7 states to change the histology code on the original abstract to the more specific histology, diffuse large B-cell lymphoma in this case. There is no time restriction for rule M7. Apply rule PH11 and code the histology as 9680/3 [DLBCL] when both DLBCL and follicular lymphoma are present in the same lymph node(s).

Ambiguous terminology is not used to code a more specific histologic type per the Heme Manual. The information submitted states only that this low grade B-cell lymphoma was "most consistent with follicular lymphoma." The term "consistent with" is an ambiguous term per SEER and cannot be used to code the histology of the 2011 neoplasm as follicular lymphoma. There was no subsequent clinical statement that this patient was diagnosed with follicular lymphoma in 2011.

Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.

Although the ambiguous terminology on the pathology report is not used to code the histology to follicular lymphoma, had there been a subsequent clinical statement that this patient had follicular lymphoma, the histology would be coded to follicular lymphoma [9690/3]. A diagnosis of follicular lymphoma followed by a diagnosis of DLBCL more than 21 days later is a new primary per rule M12.
