20130195 | Laterality--Heme & Lymphoid Neoplasms: Is laterality coded to 0 [not paired] for all lymphoma cases including paired sites (e.g., breast, lung)? | Laterality coding for lymphomas is based on the primary site not histology. Laterality describes the side of a paired organ or side of the body on which the reportable tumor originated. Determine whether laterality should be coded for each primary.
Laterality coding instructions are located in the SEER Program Coding and Staging Manual. See pages 68-70 in the 2013 manual, http://www.seer.cancer.gov/manuals/2013/SPCSM_2013_maindoc.pdf. |

20130043 | Reportability--Heme & Lymphoid Neoplasms: Is reactive plasmacytosis a reportable diagnosis that is equivalent to plasmacytoma? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Reactive plasmacytosis is not reportable unless there is another indication of a reportable neoplastic disease. Reactive plasmacytosis is "a well known pathological process described as occurring in a variety of situations including infections, autoimmune disease, diabetes mellitus, sideropenia, liver cirrhosis and neoplastic conditions including leukemia. This process, by definition, is assumed to be a reaction of the immune system to an unknown or poorly defined stimulus." Based on this definition, reactive plasmacytosis is not the same as a plasmacytoma, although it may indicate the presence of a neoplastic process, such as leukemia.

20130177 | MP/H Rules/Histology--Bladder: What rule and histology code apply when a TURB final diagnosis is small cell neuroendocrine carcinoma and high grade urothelial carcinoma? See Discussion. | The patient has a 6 cm tumor arising in posterior-lateral bladder extending to prostate, obliterates seminal vesicle, and invades pelvic wall.
TURB final diagnosis: Small cell neuroendocrine carcinoma. High grade urothelial carcinoma involves 10% of tumor.
Following the current MP/H single tumor rules, it appears Rule H8 applies. Per Rule H8, code the numerically higher code of 8120. By following this rule, it does not seem the histology code fairly represents this tumor. |
There is currently no rule in the urinary site MP/H Rules for this combination of histologies. The best option is to code the histology to 8045/3 [mixed small cell carcinoma], a combination of small cell with other types of carcinoma. The presence of small cell carcinoma drives the treatment decisions for this case.
This issue will be addressed in the next revision of the MP/H Rules. |

20120034 | Primary site--Brain and CNS: How is the primary site to be coded if a clinician used an MRI to diagnose a left cerebellar venous angioma? See Discussion. |
According to the WHO Classification of Brain/CNS Tumors, code 9122/0 (venous angioma) does not appear under tumors of the cerebellum (C716). |
Venous angiomas (9122/0) are not reportable wherever they arise. The primary site for venous angioma arising in the cerebellum is C490. The combination of 9122/0 and C490 is not reportable. Venous angioma is a venous abnormality, currently referred to as a developmental venous anomaly (DVA). |

20120090 | First course treatment/Chemotherapy: Can a drug be coded as treatment for primary sites or histologies not listed for that drug in the SEER*Rx Database? See Discussion. | The patient was diagnosed with chronic myelogenous leukemia in 2008 followed by a diagnosis of chronic lymphocytic leukemia in 2011. Per the physician statement, the patient started nilotinib in 10/2011 for CML.
The SEER*Rx Database lists CML and GIST as the only primary site/histology combinations treated using nilotinib. Can nilotinib also be coded as treatment for the CLL primary? |
SEER*Rx lists the approved sites/histologies for each drug. However, if you have a physician statement that indicates the drug was given for another site/histology, code the agent as treatment for that site/histology. | 2012 |

20120086 | Primary site: What is the single primary site used for a patient with multiple tumors in the duodenum and jejunum? See discussion. | The patient has a tumor in the jejunum and another tumor in the duodenum. Both tumors have the same histology. This disease process is a single primary per Other Sites Rule M18. Is the primary site coded to the more invasive tumor? If the tumors are equally invasive, is the primary site coded to C179? | Code the primary site to C179 [small intestine, NOS] for multiple invasive tumors of the small intestine accessioned as a single primary.
The steps used to arrive at this decision are:
Step 1: Go to the Primary Site subsection located in Section IV of the 2012 SEER Manual titled "Description of This Neoplasm."
Step 2: Apply instruction 5. "Code the last digit of the primary site code to '9' for single primaries, when multiple tumors arise in different subsites of the same anatomic site and the point of origin cannot be determined." Code the primary site to C179 [small intestine, NOS].
When multiple tumors arising in different subsites are accessioned as a single primary, the primary site is coded to the NOS code, in this case small intestine, NOS [C179]. The level of invasion does not determine the primary site, unless one or more of the tumors is in situ and another is invasive. |

20120024 | MP/H Rules/Histology--Breast: How many primaries are abstracted and what histology codes are used when a patient has two tumors, one reported as duct and lobular carcinoma and another reported as pleomorphic lobular and duct carcinoma? See Discussion. |
The pathology report indicated two tumors in the upper outer quadrant of the breast. One tumor has duct and lobular carcinoma and the other tumor has pleomorphic lobular and duct carcinoma. Per a web search, pleomorphic lobular carcinoma is a recently recognized subtype of lobular cancer. According to the MP/H Rules, Breast Equivalent Terms, Definitions, Tables and Illustrations, "pleomorphic carcinoma" is a specific type of duct carcinoma [8022/3]. This is not listed as a combined histology in Table 3. Should this be abstracted as a single primary per Rule M10, with the histology coded 8523/3 [infiltrating duct mixed with other types of carcinoma]? Or should this be abstracted as two primaries per Rule M12, with the histologies coded as 8022/3 [pleomorphic carcinoma] and 8522/3 [infiltrating duct and infiltrating lobular carcinoma]? |
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. |

20120051 | MP/H Rules/Histology--Breast: What histology code for a diagnosis of pleomorphic lobular carcinoma in situ? | For cases diagnosed 2007 or later, code the histology as lobular carcinoma, in situ [8520/2].
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 Histo rules because site specific rules exist for this primary.
Start at the SINGLE TUMOR: IN SITU CARCINOMA ONLY module, Rule H1. The rules are intended to be reviewed in consecutive order. Stop at the first rule that applies to the case you are processing. Code the histology to lobular carcinoma in situ [8520/2] because this is the only histologic type identified.
Pleomorphic lobular carcinoma is a variant of lobular carcinoma which does not have an ICD-O-3 code. It is still a lobular carcinoma. The identification of the variants of lobular carcinoma was a relatively recent discovery and the information was not available when the 2007 MP/H Rules were written. All of the lobular variants will be included in the next revision of the MP/H Rules. |

20120027 | MP/H Rules/Histology--Colon: How is histology coded if a patient has two frank invasive adenocarcinomas in one segment of the colon and multiple tubular adenomas and hyperplastic polyps throughout the entire colon without a diagnosis of familial polyposis [FAP]? See Discussion. | Does Rule H19 apply which indicates the histology is coded to 8221 [adenocarcinoma in multiple adenomatous polyps] because there are multiple polyps (number not specified) throughout the colon? Does tumor have to arise in at least one of the adenomas in order to apply Rule H19? Or, does Rule H22 apply which indicates the histology is coded to 8140 [adenocarcinoma, NOS] because the adenocarcinomas are both frank invasive adenocarcinomas and not adenocarcinoma arising in an adenoma? |
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. |

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.
