Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a patient is simultaneously diagnosed with multiple myeloma/plasma cell myeloma, plasmacytoma and plasma cell leukemia?

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

This is accessioned as one primary and the histology is coded to 9732/3 [multiple myeloma].

To arrive at this answer, it is important to first try to determine how many different unique neoplasms there are to correctly identify the number of primaries to report. Per the Heme DB, plasma cell leukemia is an obsolete term. The current term and histology code for this diagnosis is 9732/3 [plasma cell myeloma]. Plasma cell myeloma and multiple myeloma are synonyms per the Heme DB. Therefore, per Rule M2 a single primary exists when there is a single histology. That takes care of the multiple myeloma/plasma cell myeloma and plasma cell leukemia, but not the plasmacytoma.

In checking the Heme DB, the terms plasma cell myeloma and multiple myeloma are not synonyms for plasmacytoma. Therefore, we are left to determine whether the multiple myeloma/plasma cell myeloma vs the plasmacytoma represents one or two primaries.

Under the Transformation section of the Heme DB, it indicates that plasmacytoma (a chronic disease process) transforms to multiple myeloma (an acute disease process). Per Rule M9, abstract a single primary and code the acute histology when both a chronic and an acute neoplasm are diagnosed simultaneously. The histology is coded to the acute neoplasm when there is no information on the biopsy regarding which is the "later" histology. This update will be added to the Heme Manual.

Histology--Heme & Lymphoid Neoplasms: How is histology coded when a bone marrow shows slightly hypercellular marrow with acute myeloid leukemia, non-M3 type and the flow cytometry is also consistent with acute myeloid leukemia, non-M3 type?

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

Without further information as to the type of acute myeloid leukemia, code the histology to 9861/3 [acute myeloid leukemia, NOS]. If further information on the specific acute myeloid leukemia becomes available, update the histology code.

Document that the pathology report states the acute myeloid leukemia is a "non-M3 type" in a text field. This documentation will help explain the choice of 9861/3 for this case. M3 refers to one of the eight FAB subtypes described by a group of French, American, and British leukemia experts in the 1970's who divided acute myeloid leukemias into subtypes, M0 through M7. They classified the disease based on the type of cell from which the leukemia developed and how mature the cells were. This was based largely on how the leukemia cells looked under the microscope after routine staining.

In this case, all we know is that the histology does not pathologically represent the M3 (acute promyelocytic leukemia (APL)) form of acute myeloid leukemia. We do not know which type of acute myeloid leukemia it does represent.

20100088 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient has 2005 diagnosis of multiple myeloma diagnosed returns in 2010 with extramedullary plasmacytoma and a bone marrow biopsy showing plasma cell dyscrasia that is clinically stated to "consistent with a relapse of myeloma"? See Discussion.

Patient was diagnosed in 2005 with multiple myeloma and following stem cell transplant 2005 was in complete remission.

On 2/1/10 an excisional biopsy of a soft tissue right flank mass showed plasmacytoma. On 3/2/10 the bone marrow biopsy was stated to be consistent with plasma cell dyscrasia. An outside attending physician stated the bone marrow biopsy was consistent with a relapse of myeloma. There was no radiologic evidence of disease elsewhere as of Feb 2010, only the soft tissue right flank mass. Patient initially presented for post-op radiation to the right flank and was treated 3/29/10. On 8/6/10 a biopsy of a right perinephric mass was positive for plasmacytoma. Subsequent xray on 8/16/10 of the right tibia and fibula showed lytic lesion consistent with progression of myeloma.

Using the Hematopoietic Database, the plasmacytoma in 2/1/10 is a second primary. How do the rules apply to the perinephric soft tissue disease and right tibia lesion? Are they separate new primaries? Or is all of this simply a recurrence of the original 2005 diagnosis as the attending physician states?

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

Accession a single primary with the histology coded to 9732/2 [multiple myeloma]. The disease discovered in 2010 represents further advancement of former disease. Per the Abstractor Notes section in the Heme DB, it states that bone marrow involvement, lytic bone lesions, and bone tumor masses of plasma cells are common. Under the Recurrence and Metastases section in the Heme DB it further states that extramedullary (in tissue other than the bone) involvement is a generally a manifestation of advanced disease. This case is an example of such a situation.

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.

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.

20100086 Multiple primaries/Primary site/Histology--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed with mycosis fungoides in February 2010 and in May 2010 is diagnosed with peripheral T-cell lymphoma consistent with CD 30+ large cell transformation of mycosis fungoides? See Discussion Patient was diagnosed with mycosis fungoides on 2/10/2010. On 5/11/2010 the patient underwent lymph node biopsies lymph nodes that were diagnosed as peripheral Tcell lymphoma consistent with CD 30+ large cell transformation of mycosis fungoides. There is no data on the ALK protein.

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

Accession two primaries per Rule M15 which instructs you to use the Multiple Primaries Calculator to determine the number of reportable primaries. The result is that mycosis fungoides [9700/3] and peripheral T-cell lymphoma [9702/3] represents two primaries.

20100083 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a patient with a longstanding history of follicular cell non-Hodgkin lymphoma followed by a 2010 diagnosis of "B-cell lymphoma with prominent large cell component, compatible with primary cutaneous follicle center cell lymphoma"? See Discussion.

Patient has a history of follicular cell non-Hodgkin lymphoma dating back to the 1990s. The patient was treated with chemotherapy and bone marrow transplantation, radiation and rituximab. The patient had no evidence of recurrence. In April 2010 a lesion appeared on the side of the scalp above the left ear with a diagnosis of "B-cell lymphoma with prominent large cell component, compatible with primary cutaneous follicle center cell lymphoma." The oncology diagnosis is "primary cutaneous follicle center lymphoma."

Would the Multiple Primaries Calculator be used in this case?

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

Accession two primaries per Rule M15. Per the Multiple Primaries Calculator, primary cutaneous follicle center lymphoma [9597/3] following a diagnosis of follicular lymphoma, NOS [9690/3] is a new primary.

While the pathologic diagnosis was B-cell lymphoma "compatible with" primary cutaneous follicle center cell lymphoma and ambiguous terms cannot be used to identify a more specific histology, the physician confirmed the more specific diagnosis without ambiguous terminology. Therefore, this diagnosis should be coded.

20130132 Diagnostic confirmation--Heme & Lymphoid Neoplasms: What is the diagnostic confirmation code for a death certificate only (DCO) diagnosis of acute myeloid leukemia?

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

Always code diagnostic confirmation to 9 [Unknown whether or not microscopically confirmed; death certificate only] for DCO cases.

20100089 Primary site--Heme & Lymphoid Neoplasms: How is primary site coded when lymphoma is initially found in both lymph nodes and bone marrow, the pathology report is unavailable, and the physician only states that both areas are involved? See Discussion. For many consultations and/or class 2 cases, the pathology report is not available to help determine the primary site. Should the primary site be automatically coded to C421 over C77_ when both are involved? The Abstractor Notes state the primary site can be either bone marrow or lymph nodes. The physician states only that both are involved.

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

Because both the bone marrow and LN are involved, code the primary site to C779 [lymph nodes, NOS] per Rule PH22. You are to code specific nodes if a specific region is specified; however, if no region is specified, code to lymph node, NOS [C779]). When you are having problems coding primary site, go to Module 7 Primary Site Rules for Lymphomas Only. See Rule PH26. It states that you code the primary site to bone marrow when ONLY the bone marrow is involved.
