20120049 | Reportability--Heme & Lymphoid Neoplasms: Is polycythemia vera secondary to volume depletion reportable? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Secondary polycythemia vera is not reportable. See Appendix F.
Primary polycythemia vera is a condition in which there is an overproduction of blood cells due to a neoplastic process. Secondary polycythemia vera is an over production of red blood cells caused by a co-morbidity, in this case, volume depletion.

20120033 | Multiple Primaries--Hematopoietic: How many primaries are abstracted when a patient is diagnosed with essential thrombocythemia in 2007 and a bone marrow biopsy performed on 12/4/2009 shows primary myelofibrosis? See Discussion. |
The patient was diagnosed with essential thrombocythemia in 2007 and was treated with Hydrea. The 2009 bone marrow biopsy showed primary myelofibrosis which the physician states is a transition from the essential thrombocythemia. The Heme DB calls this two primaries. |
This is a single primary, essential thrombocythemia [9962/3] diagnosed in 2007. The 2010 Heme DB and Manual should not have been used to determine the number of primaries in this case. The Heme DB applies only to cases diagnosed 2010 and later. In order to determine the number of primaries, use the rules in place at the time of the subsequent 2009 diagnosis of primary myelofibrosis. Per the Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, a diagnosis of essential thrombocythemia [9962/3] followed by a diagnosis of primary myelofibrosis [9961/3] is a single primary. |

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. |

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 |

20120017 | Reportability: Is a low-grade neuroendocrine neoplasm with gastrin expression found in a periportal lymph node reportable if the clinical impression is compatible with a gastrinoma? See Discussion. |
SINQ 20110095 states that "low-grade neuroendocrine neoplasm/carcinoid tumor with expression of gastrin" is reportable. However, in this case "carcinoid tumor" is not mentioned. Is this case reportable if the expression "carcinoid tumor" is missing in the diagnosis of the pathology report? Also, does the fact that the gastrinoma was found in a lymph node affect reportability? |
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. |

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.

20120087 | MP/H Rules/Histology--Kidney: How is the histology coded and what rule(s) apply for "cyst associated renal cell carcinoma," "cystic renal cell carcinoma," and "cystic renal cell carcinoma, clear cell type"? See Discussion.
|
Per SINQ 20031008, these histologies were all coded as 8316/3 [cyst associated renal cell carcinoma]. What are the correct codes for these histologies using the 2007 MP/H Rules?
|
For cases diagnosed 2007 or later, the correct histology code for both cyst associated renal cell carcinoma and cystic renal cell carcinoma is 8316/3. The histology code for cystic renal cell carcinoma, clear cell type is 8255/3.
The steps used to arrive at these decisions are:
Step 1: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Kidney Histology rules because site specific rules have been developed for this primary.
Step 2: For the first histology, cyst associated renal cell carcinoma, start at the SINGLE TUMOR module, Rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at Rule H5. According to this rule you are to use Table 1 if you have a renal cell carcinoma and mention of a more specific renal cell type. To locate Table 1, go to Kidney under the Terms & Definitions section. Per Table 1, titled Renal Cell Carcinomas and Specific Renal Cell Types, "cyst associated" is a specific type of renal cell carcinoma. Code the histology to 8316/3 [cyst associated renal cell carcinoma].
Step 3: For the second histology, cystic renal cell carcinoma start at the SINGLE TUMOR module, Rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at Rule H5. As in the previous example you are to use Table 1 if you have a renal cell carcinoma and mention of a more specific renal cell type. Per Table 1 "cystic" is a specific type of renal cell carcinoma. Code the histology to 8316/3 [cystic renal cell carcinoma].
Step 4: For the third histology, cystic renal cell carcinoma, clear cell type, start at the SINGLE TUMOR module, Rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at Rule H6 which states you are to code histology to 8255 (adenocarcinoma with mixed subtypes) when there are two or more specific renal cell carcinoma types. To determine whether "clear cell" and "cystic" are types of renal cell carcinoma use Table 1 again. According to Table 1, both cystic and clear cell are specific types of renal cell carcinoma. Code the histology as 8255/3 [adenocarcinoma with mixed subtypes].

20120010 | Multiple primaries/Behavior--Ovary: What is the diagnosis date and histology for the primary(ies) abstracted for a patient with a mucinous cystic borderline tumor of the ovary in 2003 and a metastatic ovarian adenocarcinoma in 2011? See Discussion. | The 2011 pathology report: Spine at L3 biopsy: metastatic adenocarcinoma. Per addendum: Prior total abdominal hysterectomy specimen from 2003 was reviewed and showed an ovarian mucinous cystic tumor of borderline malignancy which has a similar morphology to the invasive adenocarcinoma seen on current specimen.
Abdominal tissue and omental biopsy: invasive and non-invasive glandular implants compatible with origin from ovarian mucinous borderline tumor.
The final diagnosis per radiation oncologist was, "recurrent ovarian cancer." |
This is a single primary. The diagnosis date is coded to 2003 and the histology is mucinous cystadenocarcinoma [8470/3]. The bone, abdominal tissue and omentum are metastatic sites. The MP/H Rules do not apply to metastases.
This is a case where an invasive or microinvasive element was missed in the original pathology. Because the entire tumor was not sectioned and placed on slides, the pathologist used their expertise when sectioning and selecting tissue to be examined. It is not a matter of poor judgment, just a fact that it is impossible to review the tissue from the entire tumor. The behavior must be changed to malignant [/3]. |

20120060 | Primary Site/Reportability: What is the primary site and reportability status of a "pancreatic endocrine neoplasm" that arises in the heterotopic pancreas of the splenic hilum that is stated to be a "well-differentiated endocrine tumor, uncertain behavior per the WHO classification"? See Discussion. | SINQ 20120035 states that well differentiated pancreatic endocrine neoplasms should be reported with histology code 8240/3. However, the pathology report provides the WHO Classification which states "uncertain behavior." Should this tumor still be reported as 8240/3?
If reportable, how is the primary site coded? The tumor arose in heterotopic pancreas (in the splenic hilum), which is pancreatic tissue found outside the usual anatomical location of the pancreas. Per the pathology report, the tumor did not invade the spleen. Should the primary site be coded to C48.1 [mesentery]? The patient is female and the coding schema for "Peritoneum for Females" would apply to the case. However, none of those CS extension codes seem to apply to this localized case.
|
This case is reportable. Code the primary site to C25.9 [pancreas, NOS] and the histology to 8240/3 [neuroendocrine tumor (NET), Grade 1].
Per the 2012 SEER Manual, code the site in which the primary tumor originated. This neoplasm arose in pancreatic tissue and will behave accordingly, even though this pancreatic tissue is not located in the usual place.
Pancreatic endocrine and neuroendocrine neoplasms are essentially the same thing. However, they are described in two different WHO classifications; the endocrine classification and the digestive system classification. The digestive system classification is more recent, and is preferred by our expert pathologist consultant. The term "neuroendocrine" is to be used now, rather than "endocrine." In the pancreas, "well differentiated endocrine tumor" is synonymous with "neuroendocrine tumor (NET) Grade 1" and is coded 8240/3. |

20120091 | Reportability/Behavior--Kidney: Is epithelioid angiomyolipoma (AML) of the kidney a reportable malignancy? See Discussion. | The addendum final diagnosis on a pathology report for a kidney core needle biopsy included the results of additional stains performed on the tissue. It indicated the morphology was most consistent with epithelioid angiomyolipoma. Further comments in the body of the report indicate these tumors are now considered malignant neoplasms with the capacity to be locally aggressive and they can potentially metastasize. There is no mention of a metastasis in this particular case. | Epithelioid angiomyolipoma (AML) [8860/0] of the kidney is not reportable unless stated to be malignant.
If the pathologist confirms this is a malignancy, apply ICD-O-3 Rule F (Matrix principle) and assign the behavior code /3. If confirmation is received, accession the case using the morphology code 8860/3 [malignant angiomyolipoma]. |
