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.

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.

20130086 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed in 2008 with chronic myeloid leukemia, chronic phase and is subsequently diagnosed with both accelerated phase (2010) and blast crisis of CML (2012)? See Discussion.

Patient diagnosed in 1/2008 with CML, Chronic phase and had a complete remission following treatment.

In 3/2010 the patient was diagnosed with CML, Accelerated phase and again had a complete remission following treatment.

In 02/2012 the patient was diagnosed with CML, Blast crisis.

How do chronic and acute neoplasms (Rules M8 - M13) relate to histologies that are stated to have Chronic, Accelerated and Blast phases per the Heme DB? These histologies don't change, does this mean Rules M8 - M13 do not apply because there isn't a change in histology? How many primaries should be accessioned in this case?

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, chronic myeloid leukemia, NOS [9863/3] diagnosed 01/2008 per Rule M2. The patient was diagnosed with CML, NOS [9863/3] in 2008 and again in 2010 and 2012. Abstract a single primary when there is a single histology.

CML, Chronic phase; CML, Accelerated phase; and CML, Blast phase (Blast crisis) are listed under the Alternate Names section for CML, NOS in the Heme DB.

Not all histologies have transformations. If a transformation is not listed in the Heme DB, Rules M8 - M13 do not apply.

20130068 Reportability--Heme & Lymphoid Neoplasms: Is polycythemia, NOS reportable? See Discussion. The physician states the patient has polycythemia. There is no confirmation of primary polycythemia nor is there mention of polycythemia vera. JAK2 was negative.

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

Polycythemia, NOS is not reportable. Polycythemia, NOS is not a synonym for polycythemia vera and, therefore, is not reportable. To be reportable the diagnosis must be polycythemia vera, or one of the other terms listed in the Alternate Names section of the Heme DB.

Polycythemia (also known as erythrocytosis) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as a hematocrit level. It can be due to an increase in the mass of red blood cells ("absolute polycythemia"); or to a decrease in the volume of plasma ("relative polycythemia").

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.

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.

20130091 Treatment, NOS--Heme & Lymphoid Neoplasms: Which guidelines are used to code treatment for hematopoietic diseases diagnosed prior to 2010?

For cases diagnosed 1/1/2010 and later, use the Hematopoietic & Lymphoid Neoplasm Manual for instructions on coding aspirin, blood thinners/anti-clotting medications, and transfusions in the field "Other Treatment."

For cases diagnosed 5/1/2002 12/31/2009, use the instructions in the SEER Manual and the instructions in "Abstracting and Coding Guide for the Hematopoietic Diseases" to code aspirin, blood thinners/anti-clotting medications, and transfusions in the field "Other Treatment."

For cases diagnosed 1/1/2001 04/30/2002 use the instructions in the SEER Manual for collection of aspirin, blood thinners/anti-clotting medications, and transfusions in the field "Other Treatment."

Prior to 1/1/2001, these treatment modalities were not collected.

20130128 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a patient has a history of chronic myelomonocytic leukemia and a 12/08/2011 subsequent biopsy of the left leg that confirms leukemia cutis? See Discussion. Patient with a history of chronic myelomonocytic leukemia has been undergoing treatment with Dacogen for three years. On 12/8/11 the patient had a biopsy of the left leg that confirmed a diagnosis of leukemia cutis. How is the leukemia cutis coded?

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

Accession a single primary, chronic myelomonocytic leukemia [9945/3], per Rule M2. Accession a single primary when there is a single histology.

This is not a new primary. Leukemia cutis is the infiltration of neoplastic leukocytes into the skin from the existing leukemia. This is an advanced phase of the leukemia and has a poor prognosis.

20130111 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a 2008 diagnosis of extralymphatic follicular lymphoma in the breast is subsequently diagnosed in 2011 with ocular follicular lymphoma? See Discussion.

The patient was diagnosed with follicular lymphoma in the breast in 2008. Per notes, there was no evidence of disease again until 2011 when the patient presented with ocular lymphoma. The physician stated this was part of the same disease process as the prior breast diagnosis. The bone marrow was not involved in either case.

Is this a single primary (recurrence) of follicular lymphoma? Or are these multiple primaries because they arise in different extralymphatic sites?

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

Accession a single primary, follicular lymphoma [9690/3] of the breast diagnosed in 2008 per Rule M2.

Accession a single primary when there is a single histology. This is a recurrence of the patient's 2008 follicular lymphoma.

20130120 Primary site--Heme & Lymphoid Neoplasms: What is the primary site for a Langerhans cell Sarcoma of the lower extremity?

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

If the bone is involved, code the primary site to bone. Langerhans more commonly starts in the bone and extends to the soft tissue.

If bone is not involved, code primary site to C492, Connective, subcutaneous and other soft tissues of lower limb and hip.

20130118 Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of Langerhans cell histiocytosis with extensive bony metastatic disease and lymphadenopathy? See Discussion. Patient was diagnosed with LCH on a biopsy of the right femur. Imaging showed extensive bony metastatic disease, extensive infiltrative perinephritis, encasement of both kidneys, renal hilar, retroperitoneal and periaortic lymphadenopathy. The right femur biopsy pathology report did not state this was metastatic.

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

Code the primary site to C419 [bone, NOS] per Rule PH30.

This patient has widely metastatic disease. Per Rule PH30, one needs to reference the Heme DB to determine the primary site and histology for this case. Per the Abstractor Notes section, Langerhans cell histiocytosis arises in the bone and many times can involve multiple bones, along with other organs and lymph nodes. Although the right femur was biopsied, this does not prove that the primary site is the femur [C402] because the patient has what was described as extensive bony metastatic disease.
