20100040 Histology--Heme & Lymphoid Neoplasms: How is this field coded for a patient with a negative bone marrow and multiple plasmacytomas in different bone sites (e.g., thoracic vertebrae and left femur)?

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] and the histology to 9731/3 [solitary plasmacytoms].

The vertebral lesions are common for plasmacytomas, as are lesions of the femur. If the patient does not meet the criteria of plasma cell myeloma/multiple myeloma (which is 20% of the leukocyte differential count), do not code the histology to multiple myeloma.

Per Rule M2, abstract a single primary when there is a single histology.

Per Rule PH3, code the primary site to the where the plasmacytoma originated and code the histology of bone () when the diagnosis is multiple plasmacytomas of the bone.

Heme & Lymphoid Neoplasms: Is a clinical remission sufficient to change the tumor status to "disease free" for a patient on long-term chemotherapy for a diagnosis of either a chronic hematologic disease, such as CML, or a myeloproliferative disorder, such as essential thrombocythemia? See Discussion.

For some patients with chronic hematologic diseases, the disease/recurrence status could change frequently as chemotherapy is started and stopped over an extended period of time. Should the tumor status for these cases always be "not disease free"? When the physician documents the patient is in clinical remission, does their status change to "NED or disease free?" There seems to be a lot of variation across the US in how registrars are coding this field. Clarification would be appreciated.

The term "disease free" is not used in a standard fashion for hematopoietic and lymphoid neoplasms.

Code the cancer status to free of disease when the physician indicates NED. For hematopoietic and lymphoid neoplasms, a physician's statement of NED, disease-free, clinical remission or no evidence of disease at this time, should be recorded with cancer status to disease free. The term "disease free" or NED means that there is no clinical evidence of disease.

20100098 Primary site/Histology--Heme & Lymphoid Neoplasms: How are these fields coded for a 2008 diagnosis of small B cell leukemia, most consistent with mantle cell leukemia that only involved the bone marrow? See Discussion. A bone marrow biopsy was done on 6/18/2008 and showed only small B cell leukemia, most consistent with mantle cell leukemia. ICD-O-3 does not list a histology code for small B cell leukemia or mantle cell leukemia.

Code the histology to 9673/3 [mantle cell lymphoma] and the primary site to C421 [bone marrow].

Mantle cell lymphoma can present in a leukemic phase. The only code available is for mantle cell lymphoma and the only primary site that could be coded would be bone marrow.

20100009 MP/H Rules/Multiple primaries--Bladder: Is a new primary accessioned for a 2009 diagnosis of transitional cell carcinoma of the bladder when the patient has a history of invasive bladder cancer NOS diagnosed? See Discussion.

A patient has a history of invasive bladder cancer diagnosed several years ago in another state. In 2009, the patient was admitted and found to have a positive biopsy for transitional cell carcinoma of the bladder.

Is this a new primary because the histology of the previous bladder cancer is unknown? When the histology of a previously diagnosed bladder cancer is unknown, should we assume the previous tumor was urothelial carcinoma?

 For cases diagnosed 2007 or later, apply rule M6. The 2009 diagnosis is not a new primary. Transitional cell carcinomas account for more than 90% of bladder cancers. If the patient actually had a rare small cell, squamous cell, or adenocarcinoma of the bladder in the past, it is highly likely it would be mentioned in the medical record. 2010
20100082 Ambiguous terminology/Reportability--Heme & Lymphoid Neoplasms: Should a case be accessioned as MDS, NOS when a consult uses ambiguous terminology (e.g., probable MDS) to describe the disease process and the bone marrow does not confirm the consult diagnosis? See Discussion. A patient is stated to have "probable MDS" by a hematology oncologist consult during an admission. A bone marrow biopsy was also performed during this admission, the final diagnosis on the pathology report is, "anemia and thrombocytopenia." The patient was not seen again by a hematology oncologist; however the patient's cardiology states, "BM biopsy was not clear whether this is MDS or another etiology."

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

This is not reportable. In effect, the original diagnosis was a rule/out MDS diagnosis. The bone marrow biopsy performed as part of the initial workup, proved that rule/out diagnosis was not valid. The subsequent statement confirms the diagnosis is not clear.

20100026 Multiplicity Counter--Kidney, Renal Pelvis: How many times is this field updated after an invasive primary is originally diagnosed? Should subsequently diagnosed in situ tumors to be included in this field? See Discussion. How should the Multiplicity Counter be coded when a patient has a renal pelvis primary [C659] diagnosed 1/23/08. The patient had one tumor, invasive grade 3 of 3 papillary urothelial carcinoma arising in the depth of a calyx in mid portion of kidney. In 6/1/09, a TURBT showed three separate high grade urothelial carcinoma in-situ lesions on the right side of the bladder, the largest tumor being 7mm. In 2/8/10, another TURBT showed one lesion on the left side of bladder, high grade urothelial carcinoma in-situ, tumor was 4mm. These are all a single primary per rule M8.

Code multiplicity counter 04. Count both invasive and in situ tumors.

Multiplicity counter would have been coded 01 in 2008. Add the three in situ tumors diagnosed in 2009 to the first tumor and update multiplicity counter to 04. Make only one update to multiplicity counter. Because the multiplicity counter was updated once, the fifth tumor diagnosed in 2010 does not need to be added.

Primary site--Heme & Lymphoid Neoplasms: Is a peripheral blood equivalent to bone marrow biopsy for the purposes of Rule PH26 and code the primary site to C421 [Bone marrow] for a marginal zone lymphoma found in peripheral blood when there was no additional workup (e.g., scans, etc.) for this case?

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

Code the primary site to C421 [bone marrow]. Our hematopoietic specialty physicians state that involvement of peripheral blood is equivalent to bone marrow involvement because the marrow produces blood. In the absence of any other involvement, per Module 7 (Coding primary sites for lymphomas) Rule PH26, it states to code the primary site to bone marrow when the only involvement is bone marrow.

Primary site--Heme & Lymphoid Neoplasms: When only pathology reports are available, how should the primary site be coded when a both a bone marrow biopsy and colon biopsy demonstrate "mantle cell lymphoma"?

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

For this case, code primary site to C189 [colon, NOS] per Rule PH24.

Mantle cell lymphoma usually begins with lymph node involvement and spreads to other tissue. However, it can begin in a lymphocyte such as those in the GI tract. Per the Abstractor Notes section in the Heme DB, patients usually present with advanced disease. About half will have some combination of B symptoms. Swelling of lymph nodes and spleen are usually present. Bone marrow, liver and GI tract involvement occurs in a very high percentage

Reportability--Heme & Lymphoid Neoplasms: Is "myeloproliferative syndrome, NOS" synonymous with "myeloproliferative syndrome" and "myeloproliferative disease" and, therefore, reportable under the new hematopoietic rules?

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

Myeloproliferative syndrome and the myeloproliferative diseases were used in the past to describe myeloproliferative neoplasms. For cases diagnosed 2010 and forward, although the term "myeloproliferative syndrome" is not currently used to describe this disease, the synonyms "myeloproliferative syndrome" and "myeloproliferative disease" were added to the database for myelodysplastic/myeloproliferative neoplasm, unclassified [9975/3].

Histology--Heme & Lymphoid Neoplasms: How is histology to be coded for acute lymphoblastic leukemia (ALL) and/or precursor B acute lymphoblastic leukemia (Pre-B ALL) for cases diagnosed 2010 and later? The Heme Database has two histology codes for this disease, both 9811/3 and 9836/3, which is the correct histology code?

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

Code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS].

See the Abstractor Notes section in the Heme DB, when determining how to code histology for a case. It indicates the code 9811/3 is effective for cases diagnosed 2010 and forward. The 9836/3 is listed as obsolete and refers you to code 9811/3. Make sure to check for a specific subtype of B lymphoblastic leukemia/lymphoma [9812/3 - 9818/3] before assigning the NOS code [9811/3].
