20120050 Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries are accessioned and what histology codes apply if a patient has a 1998 diagnosis of essential thrombocythemia and a recent clinical diagnosis of secondary myelofibrosis? See Discussion. The patient has a history of essential thrombocythemia (ET) since 1998. This has been treated daily with aspirin. A recent bone marrow biopsy was consistent with myeloproliferative disorder with excess blasts, marked extensive reticulin marrow fibrosis with osteosclerosis, excess blasts (11%) in the marrow aspirate and peripheral blood. JAK2 mutation was present in a small minority of cells. The physician stated patient was, "considered to have secondary myelofibrosis and was started on Jakafi."

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

Per Appendix F, a secondary myelofibrosis is not a reportable case.

Secondary myelofibrosis is not listed as a synonym for primary myelofibrosis in the Heme DB. The term "secondary myelofibrosis" means that the myelofibrosis was caused by, in this case, the essential thrombocythemia.

The diagnosis "consistent with myeloproliferative disorder" is also not a new reportable diagnosis. "Myeloproliferative disorder" refers to a group of diseases (an NOS category) that includes essential thrombocythemia, which was originally diagnosed in 1998, prior to reportability for this disease type.

20120049 Reportability--Heme & Lymphoid Neoplasms: Is polycythemia vera secondary to volume depletion reportable?

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

Secondary polycythemia vera is not reportable. See Appendix F.

Primary polycythemia vera is a condition in which there is an overproduction of blood cells due to a neoplastic process. Secondary polycythemia vera is an over production of red blood cells caused by a co-morbidity, in this case, volume depletion.

20120048 MP/H Rules/Primary site: Can you clarify how you interpreted the term "synchronous" to appropriately code the primary site to C68.9 [urinary tract] for SINQ 20110119 and did not use that code for SINQ 20100025 when both cases used MP/H Rule M8 to determine the number of primaries? See Discussion.

In SINQ 20100025 a patient was diagnosed with multiple urinary system tumors over a year apart. Rule M8 applies (single primary) and the primary site was left coded to the original primary site, C65.9 [renal pelvis]. In SINQ 20110119 a patient is diagnosed with multiple urinary system tumors within a month of each other, again rule M8 applies (single primary) and the primary site was coded to C68.9 [urinary system, NOS].

In both cases, rule M8 applies. However, the tumors were not diagnosed synchronously (e.g., one month apart in one case and greater than one year apart in the other). When the SINQ answer states, "same time" or "synchronous" does this mean during the same event? If not, what is the time range for "same time" or "synchronous"?

Please clarify when it is appropriate to code the primary site to C68.9 [urinary system, NOS] for Rule M8 and when it is not.

For the purpose of applying the MP/H rules, the term "synchronous" means that the two diagnoses occurred at the same time or less than or equal to 60 days apart.

The case in SINQ 20100025 was not synchronous. The first lesion in the renal pelvis [C65.9] occurred in 1/08 and the subsequent tumors were diagnosed in 5/09, more than one year apart. In this case, you do not go back to change the primary site code on the original abstract.

The case in SINQ 20110119 was diagnosed synchronously, the first lesion in the bladder [C67.9] was diagnosed in 11/09 and the second lesion in the renal pelvis [C65.9] was diagnosed in 12/09, less than 60 days apart. Because the lesions were synchronous, the primary site is coded urinary system, NOS [C68.9].

20120045 Primary site--Heme & Lymphoid Neoplasms: What is the primary site of a diffuse large B-cell lymphoma described on a PET and an abdominal CT scan as a large pelvic mass displacing bladder and uterus, inseparable from anus, right pelvic sidewall, cervix and bilateral ovaries and per the clinician as stage IIE? See Discussion.

PET: large pelvic mass displacing bladder and uterus, inseparable from anus, right pelvic sidewall, cervix and bilateral ovaries. Diffuse abnormal uptake within this mass as well as the adjacent structures. No regional hypermetabolic adenopathy is noted and no imaging evidence of distant metastatic disease. The PET also demonstrated diffuse abnormal uptake within the pelvic mass as well as the adjacent structures.

CT abdomen: large pelvic mass invading vagina and inseparable from the anus, right pelvic sidewall, cervix and bilateral ovaries.

MD states: "stage IIE with invasion of vagina."

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

Per Rule 18, code the primary site to C775 [pelvic lymph nodes]. Per Rule PH18, code the primary site to the specified lymph node region when the site of lymphoma is described only as a mass. This rule also indicates that the Code pelvic lymph nodes [C775] when the lymph nodes are described as a pelvic mass.

This rule has been effect for SEER for over 20 years. It is based on the fact that a number of lymphomas that originate in nodes are not diagnosed until those nodes become matted or fixed. The presentation is then one of a "mass" in those nodal regions.

Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a patient is diagnosed with acute monocytic leukemia in 2009 and in 2011 has biopsy confirmed granulocytic sarcoma of the cerebellum? See Discussion.

Is this a recurrence of the patient's leukemia? In 2011, the patient is found to have several masses in the cerebellum, biopsy confirmed granulocytic sarcoma. The physician stated this is an "extramedullary relapse of leukemia." The bone marrow biopsy in 2011 was negative.

 

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

Accession a single primary per Rule M3. Code histology to 9891/3 [acute monocytic leukemia] diagnosed in 2009 and primary site to C421 [bone marrow].

Per Rule M3 a single primary is reported when a sarcoma is diagnosed simultaneously or after a leukemia of the same lineage. Histology 9891/3 [acute monocytic leukemia] is listed as one of the histologies in the "same lineage." Myeloid sarcoma (9930/3) diagnosed simultaneously with or after acute myeloid leukemia (9861/3) or another leukemia of the myeloid lineage (9840/3, 9865/3-9867/3, 9869/3-9874/3, 9891/3, 9895/3-9898/3, 9910/3, 9911/3 and 9931/3).

NOTE: Under the Alternate Names section of the Heme DB, granulocytic sarcoma is a synonym for myeloid sarcoma.

Per PH10, code the primary site C421 [bone marrow] and code the histology acute myeloid leukemia, NOS (9861/3) or any of the specific AML histologies (9840/3, 9865/3-9867/3, 9869/3-9874/3, 9891/3, 9895/3-9898/3, 9910/3, 9911/3 and 9931/3) when the diagnosis is myeloid sarcoma (9930/3) AND there is a simultaneous or previous diagnosis of acute myeloid leukemia.

20120042 Histology--Heme & Lymphoid Neoplasms: How is the histology coded if a pelvic mass biopsy is positive for B-cell non-Hodgkin lymphoma and a mediastinal lymph node biopsy is positive for follicular lymphoma, grade 1? See Discussion.

CT guided core biopsy of pelvic mass is positive for B-cell non-Hodgkin lymphoma. Bone marrow biopsy is negative. Mediastinoscopy with mediastinal and pretracheal nodes biopsy is positive for follicular lymphoma grade 1 of 2. The patient has a PET demonstrating positive extensive metastatic disease with nodes in neck, chest, abdomen/pelvis and bone involvement. Should the histology be coded 9591/3 [NHL, NOS] or 9695/3 [FL, grade 1]? Which rule applies?

The table of contents for the Hematopoietic Manual indicates Module 8 for these histologies, however, Module 8 rules do not seem to apply. Continuing on to Module 9, the first rule that applies is PH30. PH30 states use the Heme DB to determine primary site/histology. The Heme DB indicates these are separate primaries, but both histologies are B-cell lymphomas.

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

Code the histology to 9695/3 [follicular lymphoma, grade 1] per PH29.

Under the Alternate Names section of the Heme DB, B-cell non-Hodgkin lymphoma is synonym for non-Hodgkin lymphoma, NOS and B-cell lymphoma, NOS.

Per PH29, one codes the histology when there is one non-specific histology (NHL, NOS) and one specific histology (FL, grade 1). You are also required to confirm the specific and the non-specific (NOS) histology represent the same primary using the Multiple Primaries Calculator. The calculator indicates these are the same primary.

20120041 Primary site/Heme & Lymphoid Neoplasms: How is the primary site coded if the patient presents with diffuse B cell lymphoma involving the nasopharynx and right maxillary sinus with bilateral cervical, right supraclavicular and axillary lymph nodes? See Discussion.

There is one mass in the nasopharynx and right maxillary sinus and the site of origin cannot be determined for this diffuse B-cell lymphoma. The patient also has bilateral cervical, right supraclavicular and axillary lymph nodes.

Should the primary site be coded per Module 7 Rule PH25 because regional nodes are involved or Rule PH22 because both regional and distant nodes are involved? If rule PH22 is used, what is the primary site?

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

Code the primary site to C119 [nasopharynx] per Rule PH25.

Per our subject matter expert, use Module 7 Rule PH25 to code the primary site to an organ (nasopharynx and maxillary sinus) because an organ(s) and its regional lymph nodes are involved. The distant lymph nodes are simply part of the staging (the lymphoma has progressed to another lymph node region).

Diffuse large B cell lymphoma originating in the oral cavity and maxillofacial region is rare, but documented. The most common sites for this rare neoplasm are Waldeyer ring, tonsils, nasopharynx, base of tongue, and palatine tonsil. There are also rare cases of diffuse large B cell lymphoma originating in the maxillary sinus. The percentage of cases arising in the nasopharynx is greater than those originating in the maxillary sinus.

20120040 Reportability--Heme & Lymphoid Neoplasms: Is the term myelodysplastic disorder a reportable term?

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

Myelodysplastic disorder is a synonym for myelodysplastic syndrome (MDS). If no further workup is done or no additional information can be found, code the histology of myelodysplastic disorder to 9989/3 [MDS] for cases diagnosed 1/1/2010 and later.

Refer to the Abstractor Notes section in the Heme DB, Abstractor Notes for MDS. Myelodysplastic (disorder) syndrome is a NOS term. Usually when this diagnosis is made, the physician will conduct further tests to determine a more specific disease in the Myeloproliferative Neoplasms group. Other specific histologies include: refractory anemia with unilineage dysplasia, refractory anemia with ring sideroblasts, refractory cytopenia with multilineage dysplasia, refractory anemia with excess blasts, myelodysplastic syndrome with del(5q), childhood myelodysplastic syndrome. If a more specific disease is diagnosed, code to that specific neoplasm.

Primary site--Heme & Lymphoid Neoplasms: What primary site and heme rule applies when a PET scan shows bilateral renal masses, hypermetabolic liver lesions and retroperitoneal lymphadenopathy, a right kidney biopsy was positive for diffuse large B-cell lymphoma, and the bone marrow biopsy was negative? See Discussion.

Patient has a history of chronic lymphocytic leukemia (CLL). February 2011 abdomen/pelvis x-ray showed development of bilateral renal masses. April 2011 PET scan showed intense areas of hypermetabolic activity corresponding to known bilateral renal masses, new hypermetabolic liver lesions, as well as left upper retroperitoneal lymphadenopathy. All findings are worrisome for malignancy. March 2011 right kidney mass biopsy was positive for diffuse large B-cell lymphoma (DLBCL). Bone marrow biopsy was negative for lymphoma.

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

Per Rule PH25, code the primary site of the diffuse large B-cell lymphoma to C649 (kidneys) and laterality to 4 (bilateral). Per PH25, code the primary site to the organ when a lymphoma is present in an and that . This patient had involvement of an organ (bilateral kidneys) as well as regional lymph nodes for that organ. The retroperitoneal lymph nodes are regional for the kidney.

The diffuse large B-cell lymphoma is an acute transformation of the chronic lymphocytic leukemia. Because the DLBCL occurred more than 21 days after the CLL, it is a new primary per Rule M10.

20120038 Reportability/Histology--Heme & Lymphoid Neoplasms: Is Monoclonal B-lymphocytosis of uncertain significance (MLUS) reportable? If so, what is the correct histology code?

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

Per Appendix F, monoclonal B-lymphocytosis of uncertain significance (MLUS) is not reportable.

Some papers point out that a lymphocyte count less than five thousand is equivalent to monoclonal B-lymphocytosis of uncertain significance (MLUS) or monoclonal B-cell lymphocytosis (MBL). A lymphocyte count of five to thirty thousand could be smoldering chronic lymphocytic leukemia (CLL). The diagnosis of MLUS is a benign process that does not meet the criteria for CLL.
