Abstract two primaries for this scenario per Rule M7. The first primary is the renal pelvis in Oct. 2006; the second primary is the ureter in Nov. 2009. The bladder tumor in July 2008 is not a new primary per Rule M8.

Compare the diagnosis date of the current (most recent) tumor to the diagnosis date of the original tumor. This applies even if the patient had six occurrences in-between these dates; you still compare the current tumor to the diagnosis date of the original tumor and ignore recurrences in this process.

Code the histology as adenocarcinoma, NOS [8140/3].

For cases diagnosed 2007 or later, the steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text) and go to the Colon Histology rules to determine the histology code for this case. The Module you use depends on the behavior and number of tumors identified in the primary site.

Start at the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY Module Rule H15. The rules are intended to be reviewed in consecutive order from Rule H15 to Rule H24. Stop at the first rule that applies to the case you are processing. Code the histology when only one histologic type is identified. In this case, the only histology present was adenocarcinoma, NOS [8140/3].

Rules H17 through H21 do not apply in this case because there is no malignancy arising in any of the adenomas or polyps scattered throughout the colon.

For cases diagnosed 2007 or later, accession two primaries, ductal with apocrine features in the left breast and lobular carcinoma in the right breast.

The steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Breast MP rules because site specific rules exist for this primary.

Start at the MULTIPLE TUMORS module, rule M4. The rules are intended to be reviewed in consecutive order within a module. The patient has tumors in both the right and left breasts.

Rule M6 does not apply because inflammatory carcinoma involves only the left breast and the patient has a different histology in the right breast and there is no mention of inflammatory carcinoma in that breast. In this situation continue to the next applicable rule.

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

Code the histology to 9732/3 [multiple myeloma].

Ambiguous terminology is used to accession cases (determine reportability) because it has been used for over 30 years to do so. Any deviation from using ambiguous terminology to determine case reportability would cause the reporting of incidence counts to vary. In this case, there was a reportable, ambiguous terminology diagnosis of multiple myeloma on the pathology report.

The instruction "Do not code histology based on ambiguous terminology" is intended to be used when there is a reportable and reportable stated in the diagnosis. Ambiguous terminology cannot be used to report the more specific diagnosis in cases of Heme & Lymphoid neoplasms. For example, if the pathology report final diagnosis was "Myeloproliferative neoplasm, probably Polycythemia Vera" the histology would be coded as myeloproliferative neoplasm, unclassifiable [9975/3]. The ambiguous terminology indicates that the genetic testing, immunophenotyping, etc., probably are not complete or are not diagnostic of the more specific disease. Wait to code the histology until there is a definite diagnosis given.

For cases diagnosed 2007 or later, accession two primaries, right breast cancer diagnosed in June 2006 and a subsequent right breast primary diagnosed in December 2011.

The steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Breast MP rules because site specific rules exist for this primary.

Start at the MULTIPLE TUMORS module, rule M4. The rules are intended to be reviewed in consecutive order within a module. Accession two primaries, tumors diagnosed more than five (5) years apart are multiple primaries.

If the pathology report stated the tumor originated in residual breast tissue, then this is a new tumor and, therefore, a new primary per rule M5. If the pathology report stated the tumor arose in the chest wall and/or there is no designation of residual breast tissue, then this is a regional metastasis and not a new primary.

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

Accession a single primary per Rule M2 which indicates you are to abstract a single primary when there is a single histology. Code the histology to 9983/3 [refractory anemia with excess blasts type 2 (RAEB-2)].

Per Appendix F, myelofibrosis, NOS, is NOT a synonym for primary myelofibrosis. Myelofibrosis, NOS, if not specified to be myelofibrosis, therefore, is not reportable.

Per PH29, code the specific histology when the diagnosis is one non-specific (NOS) histology (MDS) and one specific histology (RAEB-2) AND the Multiple Primary Calculator confirms the specific histology and NOS histology are the same primary (which it does).

Myelodysplastic syndrome, NOS is a generic disease description. In most cases, NOS histology is only the provisional diagnosis; the physician will run further diagnostic procedures and look for various clinical presentations to identify a more specific disease. The more specific myelodysplastic syndromes are: refractory anemia; refractory neutropenia; refractory thrombocytopenia; refractory anemia with ring sideroblasts; refractory cytopenia with multilineage dysplasia; refractory anemia with excess blasts; and refractory cytopenia of childhood. If the characteristics of a specific subtype of MDS develop later in the course of the disease, change the histology code to the more specific diagnosis.

This is a single primary with the histology coded as infiltrating duct and infiltrating lobular carcinoma [8522/3].

For cases diagnosed 2007 or later, the steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules manual. For a breast primary, start with the Breast Multiple Primary Rules because there are site specific rules for breast primaries.

Start at Rule M4 because this patient has multiple tumors in the same breast. The rules are intended to be reviewed in consecutive order within the applicable Module. Abstract a single primary as tumors that are lobular [8520] and intraductal or duct are a single primary.

Use the Breast Histology Coding Rules to determine the correct histology for these multiple tumors abstracted as a single primary. Start at Rule H20 as there were multiple tumors present but it is a single primary. Code the histology to 8522 [duct and lobular] when there is any combination of lobular [8520] and duct carcinoma.

The Note for Rule M10 indicates Table 1 and Table 2 are used to identify specific intraductal and duct carcinomas. Referring to Table 2 (Duct 8500/3 and Specific Duct Carcinomas) note that pleomorphic carcinoma is listed as a specific type of duct carcinoma. Pleomorphic is a word that describes the cellular appearance rather than a specific histology. It is coded when that is the only description/diagnosis given (pleomorphic carcinoma/pleomorphic duct carcinoma). In this case, both duct and lobular are describing the actual histologic types. Ignore the term "pleomorphic" and code the actual histologic descriptors, ductal and lobular. We will make appropriate changes to the breast rules in the MP/H revisions so this distinction is clear.

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

Code the histology to 9591/3 [B-cell lymphoma, NOS].

After searching the Heme DB for the term , no B-cell leukemia/lymphoma NOS code is found. However, the diagnosis of B-cell lymphoblastic leukemia/lymphoma is found. This case scenario does not specify that this is a lymphoblastic leukemia/lymphoma; therefore, the histology code 9811/3 [B-cell lymphoblastic leukemia/lymphoma, NOS] cannot be applied.

A subsequent search of the Heme DB for the term returns "Non-Hodgkin lymphoma, NOS" [9591/3]. Under the Alternative Names section of the Heme DB, B-cell lymphoma, NOS, is a synonym for Non-Hodgkin lymphoma, NOS. Therefore, the B-cell lymphoma NOS code [9591/3] is the most appropriate histology code to use for this case.

This will be added to the next revision of the Heme DB and Manual.

This is a reportable case. Code the histology as malignant gastrinoma [8153/3].

Gastrinomas are usually malignant. This one is apparently present in a metastatic site (periportal lymph node) which confirms the malignancy.

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.
