20110032 | Primary site--Heme & Lymphoid Neoplasms: What primary site is coded for Langerhans cell histiocytosis (LCH) [9751/3] when it is limited to the skin? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule PH30, use the Heme DB to determine the primary site and histology when PH1-29 do not apply, In this case, code the primary site to C449 [Skin]. According to the Abstractor Notes section in the Heme DB, the solitary form of Langerhans cell histiocytosis (LCH) [9751/3] occurs less commonly than the multisystem form of the disease; but can appear in nodes, skin and lung. This is a solitary form of LCH. Code the primary site to skin [C449].

20110031 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if patient initially diagnosed with granulocytic sarcoma on a vocal cord biopsy is subsequently diagnosed with acute myeloid leukemia more than 21 days later? See Discussion. | The patient has a history of refractory anemia with excess blasts diagnosed in 2008. A vocal cord biopsy performed on 6/2/2010 stated, "in view of a previous history of myelodysplastic syndrome this is indicative of transformation to acute leukemia" and consistent with granulocytic sarcoma. A bone marrow biopsy done on 7/19/2010 stated this was compatible with refractory anemia with excess blasts in transformation.
Granulocytic sarcoma is a solid manifestation of AML. When these diagnoses occur more than 21 days apart, are they separate primaries?
According to the WHO definition, this is acute myeloid leukemia complicating myelodysplasia. Which rule applies for this case? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case should be accessioned as two primaries. The first is refractory anemia with excess blasts in 2008, and the second is AML June 2, 2010.
As for the disease occurring in 2010, granulocytic sarcoma does not transform into AML. Per the Abstractor Notes section in the Heme DB under the term "granulocytic sarcoma," it indicates that "Myeloid sarcoma (also known as granulocytic sarcoma) may occur de novo; it may precede or coincide with AML, or represent an acute blastic transformation of myelodysplastic syndromes." This means that when granulocytic/myeloid sarcoma is seen with AML, it represents a solid manifestation of the systemically involved AML. In other words, it is all the same disease process (coded to AML) if it occurs simultaneously.
In this case, when the physician gave a provisional diagnosis of "transformation to acute leukemia" it indicated he saw the solid deposits of myeloid cells on the vocal cord. Per Rule M3, AML and myeloid (granulocytic) sarcoma appearing simultaneously are a single primary coded to AML. When the patient has AML, solid myeloid deposits (myeloid sarcoma) may appear. This is a manifestation of the AML rather than a new primary. Rule PH10 states to code the histology to AML.
Under the Transformation section in the Heme DB for refractory anemia with excess blasts (a chronic neoplasm), it indicates this disease process does transform to acute myeloid leukemia, NOS (an acute neoplasm). In this case, the chronic and acute disease processes were diagnosed at different times. 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.

20110030 | Reportability--Heme & Lymphoid Neoplasms: If and when did Langerhans cell histiocytosis (LCH) become a reportable neoplasm? See Discussion. | Per the Histiocytosis Association of America, "Over the years, cancer treatments have been used in patients with histiocytosis. Consequently, hematologists and oncologists, who treat cancer, also treat children with Langerhans cell histiocytosis. However, the disease is not cancer." | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Langerhans cell histiocytosis (LCH) [9751/3] is reportable to all agencies starting for cases diagnosed 1/1/2010 and later. See Appendix D: New Histology Terms and Codes.

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 |

20110028 | MP/H Rules/Histology--Thyroid: How many primaries and what histology(ies) are coded when the pathology report shows a, 1.9 cm Hurthle cell carcinoma, probable follicular variant of papillary carcinoma, with Hurthle cell features and a 2 mm focus of follicular variant, papillary carcinoma? See Discussion. | Right lobectomy pathology report final diagnosis states: 1.9 cm Hurthle cell carcinoma (see comment). Comment: histologic diagnosis Hurthle cell carcinoma, probable follicular variant of papillary carcinoma with Hurthle cell features. Subsequent left lobectomy one week later showed a 2 mm microscopic focus of follicular variant of papillary carcinoma, encapsulated.
None of the rules seems to fit this scenario. The number of primaries reported for this case depends on the histology coded for each tumor. Does Rule M6 (Follicular and papillary tumors in the thyroid within 60 days of diagnosis are a single primary.) or M17 (Tumors with ICD-O-3 histology codes that are at the first (xxx), second (xxx) or third (xxx) number are multiple primaries.) apply? Does the case represent a single primary because both are papillary/follicular tumors or two primaries because one is Hurthle cell carcinoma, and one is papillary/follicular carcinoma (different histology at second digit)?
To code the histology for the larger tumor in the right lobe, which rule do we apply? Rule H11 (single histology of Hurthle cell carcinoma [8290] per path final diagnosis), H15 (tumor has both follicular and papillary carcinoma [8340], per path comment), or H17 (numerically higher code for 8340 because there is both Hurthle cell and papillary/follicular carcinoma)? |
Use the Multiple Primary and Histology Coding Rules Manual for cases diagnosed 2007 or later to determine the number of primaries. This is a single primary.
The Hurthle cell carcinoma is a synonym for follicular carcinoma according to the WHO. See page 67 of the 2004 WHO Classification of Tumours of Endocrine Organs. The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules manual. For a thyroid primary, use the Other Sites MP rules under one of the three formats (i.e., flowchart, matrix or text) to determine the number of primaries because the thyroid does not have site specific rules.
Start with the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within the module from Rule M3 to Rule M18. You stop at the first rule that applies to the case you are processing.
. Follicular and papillary tumors in the thyroid within 60 days of diagnosis are a single primary. The patient has a tumor in each lobe of the thyroid with the same histology. Abstract a single primary for this patient.
Determine the histology code. For a thyroid, use one of the three formats (i.e., flowchart, matrix or text) under the Other Sites Histo rules to determine histology because thyroid primaries do not have site specific rules.
Start with the SINGLE TUMOR: INVASIVE ONLY module, Rule H8. The rules are intended to be reviewed in consecutive order within the module from Rule H8 to Rule H18. You stop at the first rule that applies to the case you are processing.
. Code follicular and papillary carcinoma of the thyroid to papillary carcinoma, follicular variant (8340). Use the comment to code the histology for the right lobectomy. "Probable" is an acceptable ambiguous term to use for coding histology. (See the Ambiguous Terms Used to Code Histology section of the General Instructions in the MP/H manual.) |

20110027 | MP/H Rules/Multiple primaries/Histology--Thyroid: How many primaries and what histology(ies) are coded when a patient is diagnosed with a single papillary carcinoma in the left thyroid lobe and multiple foci of papillary microcarcinoma in the right thyroid lobe? See Discussion. | Is the term papillary microcarcinoma being used to describe the size of the foci only, or are the right thyroid lobe lesions a different histologic type? Does rule M6 apply (single primary)? Or does rule M11 apply (multiple primaries)?
Case summary: Left thyroid with 2.2 cm papillary carcinoma and right thyroid with "multiple microscopic foci of papillary carcinoma (papillary microcarcinoma) ranging from less than 1 mm to 2 mm in greatest dimension." |
Use the Multiple Primary and Histology Coding Rules Manual for cases diagnosed 2007 or later to determine the number of primaries. This is a single primary.
For thyroid cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult. The histology is the same in both lobes of the thyroid.
The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules manual. For a thyroid primary, use the Other Sites MP rules under one of the three formats (i.e., flowchart, matrix or text) to determine the number of primaries because the thyroid does not have site specific rules.
Start with the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within the module from Rule M3 to Rule M18. You stop at the first rule that applies to the case you are processing.
. This patient has multiple papillary carcinomas of the thyroid diagnosed simultaneously; no other rule applies, so this is a single primary. Abstract a single primary for this patient.
Determine the histology code. For a thyroid, use one of the three formats (i.e., flowchart, matrix or text) under the Other Sites Histo rules to determine histology because thyroid primaries do not have site specific rules.
Start with the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY module, Rule H18. The rules are intended to be reviewed in consecutive order within the module from Rule H18 to Rule H31. You stop at the first rule that applies to the case you are processing.
. Code papillary carcinoma of the thyroid to papillary adenocarcinoma, NOS [8260]. |

20110024 | MP/H Rules/Histology--Breast: How is histology coded, and which MP/H rule applies for a diagnosis of ductal carcinoma in situ with clear cell features? See Discussion. | None of the histology rules for in situ breast seem to apply to this case:
|
For cases diagnosed 2007 or later: Code 8523/2 [intraductal carcinoma mixed with other types of in situ carcinoma]. Rule H6 should apply to this case.
The wording in the Rule H6 needs to be clarified to handle a case of intraductal carcinoma with one or more subtypes that are not ductal. This will also require a modification to Table 3. A row needs to be added to the table labeled, "Intraductal and one or more of the histologies in Column 2." The Column 3 text for the newly added row would read, " Intraductal mixed with other types of carcinoma." The appropriate histology code to be reported per Column 4 would be 8523/2. This will be done in the next revision of the rules. |

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.

20110020 | Heme & Lymphoid Neoplasms: How is cancer status to be coded when a patient diagnosed with MDS, undergoes treatment, but the MDS subsequently transforms to AML? | If the bone marrow no longer shows evidence of MDS, the cancer status for the MDS is disease-free. When cancer status is coded as disease-free (NED), it means that currently there is no clinical evidence of this disease (MDS). | 2011 | |
|
20110019 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when bilateral testes are involved with lymphoma? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This is a single primary per Rule M2 which indicates to abstract a single primary when there is a single histology. Code the histology to 9590/3 [lymphoma] and the primary site to C629 [testes. Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal lymphomas occur in multiple sites, particularly in paired sites.
