20200080 | Reportability/Histology--Pancreas: Is a diagnosis of insulin-producing (insulinoma) epithelioid neoplasm reportable if made 2021 and later? If so, is the histology coded as 8151/3 per the ICD-O-3.2 Coding Table? See Discussion. |
The ICD-O-3.2 Implementation Guidelines and ICD-O-3.2 Coding Table indicate that insulinoma, NOS has changed behavior from /0 to /3 for cases diagnosed 2021 and later. However, the ICD-O-3.2 Implementation Guidelines do not indicate whether this change applies to tumors described as above. Insulinomas are generally neuroendocrine tumors/neoplasms, so it seems any neuroendocrine tumor described as an insulinoma should be collected as 8151/3, but does that apply to an epithelioid tumor/neoplasm also described as insulinoma? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
If the diagnosis includes insulinoma, it is reportable and coded 8151/3. Insulin-producing epithelioid neoplasm alone, without mention of insulinoma, is not reportable. |

20091081 | Reportability/Histology--Brain and CNS: Is an "inflammatory myofibroblastic tumor" reportable for Brain and CNS sites? See Discussion. | Histology code 8825/1 (Inflammatory Myofibroblastic Tumor) is not listed in the ICD-0-3 Primary Brain and CNS Site/Histology listing for reportable Brain/CNS tumors. | If the inflammatory myofibroblastic tumor is primary in one of the sites specified below and diagnosed 1/1/2004 or later, it is reportable.
Reportable brain and CNS tumors are any benign and borderline primary intracranial and CNS tumors with a behavior code of /0 or /1 in ICD-O-3 diagnosed 1/1/2004 and later, of the following sites:

20071097 | Multiplicity Counter--Thyroid: How is multiplicity counter to be coded for a thyroid cancer presenting as multiple foci? See Discussion. | Thyroidectomy showed papillary thyroid carcinoma. Path diagnosis: tumor focality: multifocal. Path described 3 foci of tumor on each side. The main tumor mass in right thyroid was 1.5 cm. Smaller foci of tumor ranged in size from .1 cm to 1.0 cm. Per guidelines, "we still don't count foci as tumors for the purpose of these rules, even if there is more than one." The 1 cm tumor was probably macroscopic in size. Do we count it in the multiplicity counter? Do we count only the 1.5 cm main tumor mass? | If the number of tumors is known, code the number in Multiplicity Counter. If foci are measured, include them in the multiplicity counter. If the only information available is "multiple foci" assign code 99. For the case above, code 06 in the multiplicity counter (3 tumors on each side). |

20000248 | Date of Diagnosis: When doing follow-back at nursing homes on DCO cases, we find it difficult to code diagnosis date because the nursing home records are often vague or incomplete. Should the diagnosis date be coded as unknown (excluded from SEER database), the date of death, or the approximate date of diagnosis as reported on the death certificate? | If the nursing home record indicates that the patient had cancer, use the best approximation for date of diagnosis.
If the record says the patient had cancer when admitted, but it does not provide a date of diagnosis, use the date of admission as the date of diagnosis.
If there is no mention of cancer in the nursing home record and/or all work-up in the record is negative, assume the cancer was discovered at autopsy. Use the date of death as the date of diagnosis, and leave as a Death Certificate Only case. |

20170062 | Race, ethnicity: How do you code race for someone from New Zealand? |
I recently did a presentation on coding the data item Race. In my presentation I discussed understanding geography help code race in some circumstances. One of the slides demonstrates how large Polynesia is and what Pacific islands are found in Polynesia, such as, Tahiti, Samoa, and even Hawaii, all of which have their own codes. Someone in the audience asked "How do you code New Zealand? Upon some research, New Zealand is not listed in Appendix D of the SEER coding manual. We could code them 01-White. But research shows there is a very large indigenous population. Technically, New Zealand is located within the boundaries of Polynesia - Code 25 (Polynesian). |
If the only information you have on race is that the person is from New Zealand, code race as white. This is based on the instructions for Australia, the closest neighbor to New Zealand as no other guidance was found. |

20150058 | MP/H Rules/Multiple Primaries: Is this counted as one or two primaries?
Patient is diagnosed with SCC esophageal cancer. Work-up reveals a lung nodule. Lung FNA (cytology) is read by the pathologist as SCC, favor metastatic esophageal SCC. However, the managing physicians are treating the patient as two separate primaries. |
If the patient is being managed and treated as a case of primary lung cancer, report the lung diagnosis as a separate primary. |

20041026 | CS Tumor Size--Ovary: The size of a cyst is not coded in this field. However, can the size of a "cystic mass" be coded in this field? See Discussion. | The specimen consists of a cystic mass which weighs 1520 grams and measures 23 x 17 x 10 cm. | If the tumor is described as a "cystic mass" and only the size of the entire mass is given, code the size of the entire mass, because the cysts are part of the tumor itself.
Please note: Ovarian cancer stage is not based on tumor size. |

20190022 | Solid Tumor Rules (2018)/Histology--Lung: Is histology code or the number of primaries assigned differently in SINQ 20180093 if the word "pattern' was omitted? See Discussion. |
Regarding the answer to SINQ 20180093: This is a single primary; coded 8140/3 adenocarcinoma. In the biopsy and the two tumors found on lobectomy, the specific adenocarcinoma histologies are described as acinar predominant pattern, solid growth pattern and lepidic predominant pattern. You do not code a pattern, so rule M7 above applies and this is a single primary. My question is based on Note 2 in Coding Multiple Histologies for lung cancers that says: Predominantly describes the greater amount of tumor. Predominant and majority are synonyms. Per the CAP protocol, the term predominant is acceptable for the following specific subtypes of adenocarcinoma. For these subtypes only, the word predominant is used to describe both the subtype and the grade of the tumor. |
If the word "pattern' was omitted, you would abstract multiple primaries per the Lung Solid Tumor Rule M6 and code histology to adenocarcinoma, acinar predominant (8551/3) and adenocarcinoma, lepidic predominant (8250/3) per Rule H4 as the word "pattern' is not included in each histology. |

20150059 | Primary Site--Liver: What is the topography code for combined hepatocellular carcinoma/cholangiocarcinoma (M-8180/3) especially when there is no documentation that intrahepatic bile duct is the tumor site? Reports usually just indicate a liver mass(es) but since the intrahepatic ducts are within the liver, is the code C221 due to the cholangiocarcinoma component, thus making the case stageable? |
If there is no further information about where the cancer originated, assign C220. Use ICD-O-3 as the source for coding topography. The topography code associated with combined hepatocellular and cholangiocarcinoma (8180/3) is C220 when there is no other information available, according to ICD-O-3. |

20210035 | Update to current manual/Lymphovacular invasion--Thyroid: Are psammoma bodies only recorded as vascular invasion in papillary thyroid cancer cases? See Discussion. |
For example, total thyroidectomy specimen shows right lobe papillary thyroid carcinoma, 4.2 cm, unencapsulated, with numerous psammoma bodies in non-tumoral thyroid parenchyma, without angioinvasion; left lobe with papillary thyroid carcinoma, 0.6 cm, encapsulated, with capsular invasion, with intralymphatic psammoma bodies in non-tumoral thyroid parenchyma, without angioinvasion. The synoptic summary documents vascular invasion present (psammoma bodies only). |
If you are collecting lymphovascular invasion (LVI) for thyroid cases, record "vascular invasion present (psammoma bodies only)" as vascular invasion (code 1, Lymphovascular Invasion Present/Identified) in the LVI data item. Use a text field to specify that this is vascular invasion by psammoma bodies. |
