20110147 | Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How is the histology coded when no bone marrow examination is performed but the peripheral blood flow cytometry listed several differential diagnoses and the physician states the diagnosis is small lymphocytic lymphoma? See Discussion. | The peripheral blood flow cytometry results state, "findings consistent with a small mature B-cell neoplasm, differential - marginal zone lymphoma, lymphoplasmacytic lymphoma, and atypical CLL." The physician states the diagnosis is "SLL." No bone marrow examination or CT scan was done to assess whether the patient had lymphadenopathy.
Per Rule PH5, if the diagnosis is B-cell CLL/SLL and peripheral blood is involved, the histology is coded to B-CLL/SLL [9823/3]. Should the primary site and histology be coded to bone marrow [C421] and CLL/SLL [9823/3] per Rule PH5 despite the physician's diagnosis of SLL [9670/3]? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This is a single primary and the primary site and histology is coded as bone marrow [C421] and CLL/SLL [9823/3]. The code 9670/3 [malignant lymphoma, small B lymphocytes, NOS] used for SLL is now obsolete.
Per the Abstractor Notes section in the Heme DB indicates that SLL is, "usually associated with CLL and coded CLL/SLL 9823/3. Small lymphocytic lymphoma (SLL) is almost identical to CLL. A somewhat arbitrary distinction is drawn between them based on the relative degree of marrow and nodal involvement and the numbers of circulating cells."
Per the Definition section in the Heme DB it states that, "CLL by definition involves blood and bone marrow at time of diagnosis." Check the PRIMARY SITE and MODULE RULE sections that indicate the primary site is C421, Rule PH5. Per this rule, code the primary site bone marrow (C421) and code the histology B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) [9823/3] when the diagnosis is B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) AND peripheral blood is involved (the bone marrow may also be involved).
This may appear to contradict the physician's diagnosis, but the 2008 WHO no longer codes CLL and SLL as separate neoplasms, rather one neoplasm, CLL/SLL, which reflects the actual neoplastic process. Those patients with SLL usually manifest CLL during the neoplastic process and those patients with CLL usually manifest SLL during the neoplastic process. WHO recommends coding to CLL/SLL rather than coding two primaries when the other neoplasm manifests.

20110014 | MP/H Rules/Histology--Corpus Uteri: Which MP/H rule applies in coding histology for a "high grade endometrioid adenocarcinoma with squamous differentiation (adenosquamous carcinoma)"? See Discussion. | Is the pathology describing a specific histology, adenosquamous carcinoma [8560/3]? Or is this a combination/mixed histology code per rule H16? The Rule H16 instruction is to code a mixed histology code, 8323/3 [mixed cell adenocarcinoma] from Table 2 when two or more of the histologies are present (i.e., endometrioid and squamous in this case). | For cases diagnosed 2007 or later: Endometrioid adenocarcinoma with squamous differentiation is coded to 8570 [Adenocarcinoma with squamous metaplasia].
The following row needs to be added to Table 2 in order to be able to correctly use the MP/H rules to reach this conclusion.
Column 1: Endometrioid adenocarcinoma Column 2: Squamous metaplasia Squamous differentiation Column 3: Adenocarcinoma with squamous metaplasia Column 4: 8570
The change will be made in the next revision of the rules. |

20110102 | Reportability--Heme & Lymphoid Neoplasms: For cases diagnosed 2010 and later, are idiopathic thrombocytopenia and autoimmune thrombocytopenia reportable? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Idiopathic and autoimmune types of thrombocytopenia are not reportable. Thrombocytopenia and thrombocythemia are not synonyms. Cytopenia and cythemia have different definitions. See Appendix F: Non-Reportable List for Hematopoietic Diseases.

20110023 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported in a patient with a November 2009 diagnosis of refractory anemia and a 10/25/2010 biopsy diagnosis of refractory anemia with excess blasts type 2 with ringed sideroblasts that the clinician indicates actually demonstrates progression to AML? See Discussion. | Refractory anemia, NOS diagnosed in November 2009. The diagnosis on a bone marrow biopsy performed on 10/25/10 is myelodysplastic syndrome - refractory anemia with excess blasts type 2 with ringed sideroblasts. Per the medical oncologist, in the 12/16/10 clinic note it states, "Pt underwent bone marrow biopsy on 10/25/10 and ultimately this marrow demonstrates progression to AML.
When applying the Hematopoietic Rules, the refractory anemia, NOS and the myelodysplastic syndrome - refractory anemia with excess blasts type 2 with ringed sideroblasts is the same primary. However, the refractory anemia NOS and the AML are multiple primaries. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
First, note that myelodysplastic syndrome (MDS) is a term that includes a number of diseases. Refractory anemia, NOS and refractory anemia with ringed sideroblasts are types of MDS. These two diseases are an NOS and a more specific disease, which is accessioned as one primary per Rule M7.
Next, assess the change from refractory anemia to AML. In checking the Heme DB, AML is listed under transformations for refractory anemia with ringed sideroblasts. This patient has a chronic disease (refractory anemia with ringed sideroblasts) and an acute disease (AML). Per Rule M10, abstract as multiple primaries when a neoplasm is originally diagnosed in a chronic (less aggressive) phase AND second diagnosis of a blast or acute phase more than 21 days after the chronic diagnosis.

20110039 | Multiple primaries/Primary site--Heme & Lymphoid Neoplasms: What are the primary sites and how many primaries are abstracted, when 2004 diagnosis of grade 2 follicular lymphoma of the bilateral breasts is subsequently diagnosed with a 2010 diagnosis of diffuse large B-cell lymphoma (40%) and grade 3a follicular lymphoma (60%) of a left arm nodule? See Discussion. | Follicular lymphoma was diagnosed 7/2004, grade 2 per biopsy of the bilateral breasts. Bone marrow biopsy was positive for lymphoma involving 10% of bone marrow. Imaging showed extensive lymphadenopathy mainly in abdomen/pelvis with an 8 cm mass in the right pelvis. Smaller lymph nodes were noted in the left periaortic region and also some small precarinal lymph nodes. This was a stage IVA lymphoma. The patient had six cycles of CHOP/R with an excellent response. Per the clinician's notes on 12/2005, there was no evidence of recurrence or no sign of active disease. The plan was to follow up with the patient in 6 months.
08/22/06 imaging showed new disease in the bilateral chest wall. 8/2006 bilateral breast nodule biopsies, are positive for grade 1-2 follicular lymphoma. The patient was treated with Rituxan. Per clinician's 3/2007 note, no active disease is noted. Patient was regularly followed with no evidence of disease until 10/2010. At that time, the patient had a left arm nodule biopsy which was positive for diffuse large B cell lymphoma (40%) CD positive and grade 3a follicular lymphoma (60%). RICE was recommended due to "transformation" per oncologist. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule M10, this case should be accessioned as two primaries when a neoplasm is originally diagnosed as a chronic neoplasm (is follicular lymphoma (FL), grade 2) AND there is a second diagnosis of an acute neoplasm (diffuse large B-cell lymphoma) more than 21 days after the chronic diagnosis.
Code the histology for the first primary to 9691/3 [follicular lymphoma (FL), grade 2] and the primary site to bilateral C509 [breast, NOS]. FL can start as an extranodal disease; breast is one of the sites in which it originates. It is unlikely that the lymphoma extended from the nodes to the breast, but highly likely that it extended from the breast to the nodes.
Per Rule M4, abstract the 2010 disease process as a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s). Per Rule PH11 the primary site is coded to C779 [lymph nodes, NOS] and the histology is coded to 9680/3 [diffuse large B-cell lymphoma (DLBCL)]. Rule PH11 states one is to code the primary site to the site of origin, lymph node(s), lymph node region(s), tissue(s) or organ(s) and histology to diffuse large B-cell lymphoma (DLBCL) (9680/3) when DLBCL and any other non-Hodgkin lymphoma are present in the same lymph node(s), lymph node region(s), organ(s), tissue(s) or bone marrow.

20110130 | MP/H Rules/Multiple primaries--Lung: Should a July 2011 left lower lobe mass with adenocarcinoma be accessioned as an additional primary per Rule M7 or as the same primary per Rule M12 if it is diagnosed subsequent to a September 2010 right upper lobe/right middle lobe lobectomy with clear cell adenocarcinoma in one nodule and adenocarcinoma in another nodule? See Discussion. | 09/2010: RUL/RML lobectomy: Two separate nodules. One nodule showed clear cell adenocarcinoma, and the other showed adenocarcinoma (NOS). Potential brain metastasis per scan. Patient also received chemotherapy. These are two separate primaries per rule M11.
07/2011: New LLL mass + satellite nodule, biopsy of LLL mass compatible with adenocarcinoma (NOS). Is the 07/2011 an additional new primary per rule M7? Or is it the same primary as the 09/2010 adenocarcinoma per rule M12? |
For cases diagnosed 2007 or later: The 2011 diagnosis of adenocarcinoma, NOS in the left lower lobe lung is a separate primary.
The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules manual. For a lung primary, use the Lung Multiple Primary rules to determine the number of primaries.
The 2010 right lung bi-lobectomy showed two separate tumors that were determined to be two primaries: clear cell adenocarcinoma [8310/3] and adenocarcinoma, NOS [8140/3]. The histology of the new left lung mass is adenocarcinoma, NOS [8140/3].
Start at Rule M3 using the MULTIPLE TUMORS module because this patient has more than one tumor. The rules are intended to be reviewed in consecutive order within the module (i.e., from Rule M3 to Rule M12 in this case). Stop at the first rule that applies to the case you are processing. This patient has two tumors in each lung with ICD-O-3 histology codes that are different at the second (xxxx) digit. Abstract the LLL adenocarcinoma as a new primary [C343, 8140/3].
The patient has two tumors in each lung. The right lung showed adenocarcinoma and clear cell adenocarcinoma. The two tumors in the left lung were both adenocarcinomas. Clear cell adenocarcinoma [8310] on the right is different at the second digit from adenocarcinoma [8140] on the left. Rule M12 cannot be applied to this case, because Rule M7 is the first rule that applies to this case when processing the rules in consecutive order.

20110116 | MP/H/Histology--Lung: What is the histology code for "heterologous biphasic sarcomatoid carcinoma of the lung with prominent rhabdomyoblastic and adenoca differentiation"? |
The expert pathologist recommends coding histology to 8980/3 [Carcinosarcoma] for this combination histology. Expert consultation: The designation "carcinosarcoma" is given when the pathology shows differentiation in both the sarcomatous (rhabdomyoblastic) and carcinomatous (adenoca) elements. This is emphasized in the path for this case with the term "biphasic." The term "heterologous" mean that the sarcomatous component is of a type not normal to lung. Rhabdomyoblastic means skeletal muscle differentiation. Because skeletal muscle is not normally found in lung it is heterologous. If it were smooth muscle, it would be homologous because smooth muscle is found in lung (as a part of the bronchi). |

20110109 | 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.

20110029 | DCO/Multiplicity Counter/Type of Multiple Tumors: How are these fields coded for an unknown primary reported as a DCO case? See Discussion. | Do DCO cases have default values for the Multiplicity Counter and Multiple Tumor Reported as One Primary fields? Should these fields be coded as 88 or 99?
In the data item pages for these fields, there is only a reference to see the NAACCR Death Clearance Manual. However, this manual does not provide an answer. There is guidance to use code 88 for unknown primaries but we noticed that SEER edits skip enforcing this requirement for DCO cases (see SEER IF205 and 206). |
For a DCO case reported as an unknown primary [C809], code Multiplicity Counter to 99 [Unknown if multiple tumors; not documented] and Type of Multiple Tumors Reported as One Primary to 99 [Unknown]. | 2011 |
|
20110070 | MP/H Rules/Histology--Endometrium: How is histology coded when clear cell adenocarcinoma [8310/3] is stated to involve a "1.5 cm endometrial polyp"? See Discussion. | The CAP formatted pathology report histology field states, "Clear cell adenocarcinoma, NOS 98310/3)" and the tumor size comment field states, "Carcinoma involves a 1.5 cm endometrial polyp." Does rule H11 apply? Is the histology coded to clear cell adenocarcinoma [8310/3] because this is one histologic type identified in the CAP formatted histology field? Or should rule H12 apply and the histology coded as clear cell adenocarcinoma arising in a polyp [8210/3]? Or should we code the higher histology per rule H17 apply because clear cell adenocarcinoma and adenocarcinoma in a polyp are two specific histologies?
For colon primaries, whether or not the tumor arose in a polyp is quite important. Is this also the case for primaries listed in the Other Sites category? |
Code histology to 8310/3 [clear cell adenocarcinoma]. The Multiple Primary and Histology Coding Rules Manual is the correct source for coding histology for cases diagnosed 2007 or later.
The following steps are used to determine the histology code:
Open the Multiple Primary and Histology Coding Rules manual. For an endometrial primary, use the Other Sites Histo rules to determine the histology code because endometrium does not have site specific rules.
Go to the SINGLE TUMOR: INVASIVE ONLY module, which starts at Rule H8.
. Code clear cell adenocarcinoma [8310/3] because only one histologic type is identified. |
