20190023 | First course of treatment/Radiation therapy--Kidney: Patient has a CT-guided biopsy of a right renal mass with procedure details under the Interventional Radiology Procedure Note stating "Gelfoam tract embolization." Is this particular embolization treatment? |
Gelfoam tract embolization for a CT-guided renal biopsy is not treatment. It is a method to plug the biopsy track to reduce the risk of hemorrhage. |

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. |

20190021 | Sequence Number Central--Brain and CNS: How is Sequence Number--Central coded for current/recent benign brain/CNS tumors when the patient has a history of an additional non-malignant CNS tumor diagnosed prior to 2004 (when these tumors became reportable to SEER)? See Discussion. |
We are confused by the SEER Program Coding and Staging Manual 2018 instruction that states: This sequence number counts all tumors that were reportable in the year they were diagnosed even if the tumors occurred before the registry existed or before the registry participated in the SEER Program. Does this rule apply to benign and borderline CNS tumors? Does this mean that any non-malignant CNS tumor diagnosed prior to 2004 should NOT be included in the sequencing (in the 60s range) if we were collecting non-malignant CNS per our State Registry reporting requirements prior to 2004? Example: Patient has a March 2017 diagnosis of right sided vestibular schwannoma (C724-1, 9560/0) and a prior history of left sided acoustic neuroma (c724-2, 9560/0) diagnosed in 1991. How should sequence be coded for each primary in our file? |
For your example, code the Sequence Number--Central as 61 for the 1991 diagnosis if this was a state registry requirement in 1991 and code 62 for the 2017 diagnosis. |

20190020 | Solid Tumor Rules (2018)/Histology--Head & Neck: What table in the Head and Neck Solid Tumor Rules applies to tumors of the lip (C000-C009)? The rules apply to all tumors in sites C000-C148, C300-C339, C410, C411, C442 and C479, but none of the histology tables include the lip. See Discussion. |
Example: Patient has a secretory carcinoma of minor salivary gland tissue (mammary analogue secretory carcinoma [MASC]) of the mucosal lower lip; it is unclear which table to use and how to arrive at the correct histology using the H Rules. Rule H1 (code the histology when only one histology is present) states, Note 1: Use Tables 1-9 to code histology. There is no table that includes the lip. The correct histology should be 8502 which is listed in Table 6 (Tumors of Salivary Glands) however this does not correspond to minor salivary glands of the mucosal lip (site C003 per ICD-O-3 coding instruction). The 2018 ICD-O-3 Update table does not include this histology, however Table 6 indicates code 8502 (secretory carcinoma) is a new code that was approved by IARC/WHO. The ICD-O-3 only includes this histology as secretory carcinoma of breast. Therefore, in order to arrive at the correct histology, one must be aware of previous SINQ entries 20160036 and 20130003 that indicate secretory carcinoma (or MASC) is histology 8502. However, these are related to MP/H Rules, so registrars may be hesitant to apply this guideline to cases coded using Solid Tumor Rules. |
Assign 8502/3 using Table 6 of 2018 Solid Tumor Rules for Head and Neck. Table 4 notes that there is no ICD-O site code for minor salivary glands. Many minor salivary glands are located in the lips, inner cheek (buccal mucosa), and there are extensive minor salivary glands in the linings of the mouth and throat. Code to the site in which the salivary gland is located. Mammary analog secretory carcinoma (MASC), also called secretory carcinoma, is a rare, generally low-grade salivary gland carcinoma characterized by morphological resemblance to mammary secretory carcinoma and ETV6-NTRK3 gene fusion. Common sites are of the parotid gland, oral cavity, submandibular gland, and the axilla with rare sites being the face including the lips, trunk, and limbs according to WHO Classification of Head and Neck Tumors, 4th edition and WHO Classification of Skin Tumors, 4th edition. This histology is usually associated with primary site of breast and you may get an edit that you can override. |

20190019 | Solid Tumor Rules 2018/Histology--Brain and CNS: How is histology coded for a single meningioma tumor when the histology is a meningioma comprised of multiple specific subtypes/variants? See Discussion. |
Example: Patient has a left cerebral meningioma that is meningothelial meningioma (9531) and two right-sided cerebral meningiomas: one that is transitional meningioma (9537) and the other that is meningioma, transitional and angiomatous, WHO Grade I. If the histology for the mixed tumor is 9534 (angiomatous meningioma), then there are three primaries. If the histology is 9537 (transitional meningioma), then there are two primaries. Per Table 6, angiomatous meningioma is 9534/0 and transitional meningioma is 9537/0. There is no mixed histology coding rule, or mixed histology meningioma code. There is also no default rule that would instruct registrars to code the numerically higher ICD-O code or to default to a meningioma (NOS) histology code. |
Code the histology for the meningioma, transitional and angiomatous, WHO Grade I to Meningioma, NOS (9530/0). Since a mixed meningioma ICD-O code has not been proposed by WHO, we consulted with our expert neuropathologist. The other option is to follow back with the pathologist and code what they feel is the predominant type. A new histology rule for coding mixed meningiomas will be added in a future update of CNS rules. |

20190018 | Histology--Thyroid: Should any mention of encapsulated be included in the histology coding (8343/3 vs. 8260/3) for papillary thyroid carcinoma cases? See Discussion. |
Example: Left thyroid lobectomy with final diagnosis When the only mention of encapsulation is included in the tumor characteristics of the College of American Pathologists (CAP) summary, not the pathologist's choice of histologic type, what is the preferred histology? |
Assign 8343/3 for encapsulated variant of papillary thyroid carcinoma. If the pathology report is not available, use the histologic type in addition to other information in the CAP Protocol. |

20190017 | Reportability--Heme & Lymphoid Neoplasms: The term indolent systemic mastocytosis is listed in the 2018 ICD-O-3 Histology Update table with borderline behavior (9741/1). However, smoldering systemic mastocytosis is listed in the Hematopoietic and Lymphoid Database (Heme DB) as an alternate name for histology 9741/3. Are smoldering systemic mastocytosis and indolent systemic mastocytosis synonymous? If so, should smoldering systemic mastocytosis also be removed from the Heme DB alternate names listing? See Discussion. |
In addition to the issue mentioned above, there is a SINQ answer that conflicts with the 2018 ICD-O-3 Histology Update table. SINQ 20130134 indicates indolent systemic mastocytosis is reportable for cases diagnosed 2010 and forward. There is no date restriction indicating the SINQ note applies only for cases diagnosed 2010-2017. Since indolent systemic mastocytosis was changed to borderline (9741/1) for diagnosis year 2018+, should the diagnosis year range be updated for this SINQ answer? |
Smoldering systemic mastocytosis is reportable, 9741/3. Indolent systemic mastocytosis is not reportable as of cases diagnosed 2018, 9741/1. Smoldering systemic mastocytosis and indolent systemic mastocytosis are not synonymous. Smoldering differs from indolent based on diagnostic criteria and burden of disease; indolent is low whereas smoldering is high burden of disease that can progress to aggressive systemic mastocytosis or mast cell leukemia. We will update SINQ 20130134. |

20190016 | Update to current manual/SS2018--Breast: Should Code 3 of the Summary Stage 2018 (SS2018) for Breast designate the intramammary and infraclavicular lymph nodes as being ipsilateral? Similarly, should Code 7 designate infraclavicular lymph nodes as contralateral/bilateral? Laterality (ipsilateral, contralateral/bilateral) is included for axillary and internal mammary nodes in the respective codes. |
Based on your question, a review of the AJCC manual was done to clarify how these nodes would be coded. A review of Extent of Disease (EOD) Regional Nodes and EOD Mets was also done. That information is correct and in line with AJCC 8th edition. We apologize that SS2018 was not updated accordingly and thank you for bringing this issue to our attention. Per AJCC, infraclavicular and intramammary nodes are ipsilateral for the N category. Contralateral or bilateral involvement are included in the M category. The following will be applied to the planned 2020 update of the SS2018 manual. Code 3 Ipsilateral will be added to Infraclavicular and Intramammary Infraclavicular (subclavicular) (ipsilateral) Intramammary (ipsilateral) Code 7 The following will be added under Distant lymph nodes Infraclavicular (subclavicular) (contralateral or bilateral) Intramammary (contralateral or bilateral) |

20190015 | Update to current manual/EOD 2018--EOD Primary Tumor: Should Note 6 in Extent of Disease (EOD) Primary Tumor for the schemas Fallopian Tube, Ovary, and Primary Peritoneal Carcinoma be revised to exclude pelvic sites? See Discussion. |
There is a discrepancy between Notes 3 and 6 in the schemas Fallopian Tube, Ovary, and Primary Peritoneal Carcinoma for EOD Primary Tumor. Note 3 describes extension/discontinuous metastasis to the pelvic sites (code 450) and includes the sigmoid colon, rectosigmoid and rectum since these are all pelvic sites. However, Note 6 also includes rectosigmoid and sigmoid colon. Note 6 is describing extension/discontinuous metastasis to the abdominal sites (600-750), so it should include rectosigmoid or sigmoid colon (since those are pelvic sites). Note 6 indicates, Intestine, large (except rectum). In the previous Collaborative Stage, the corresponding note used to also include: except sigmoid colon, rectosigmoid and rectum. Did sigmoid colon and rectosigmoid get removed from the list here? That is, should Note 6 read, Intestine, large (except sigmoid colon, rectosigmoid, rectum)? Involvement of the sigmoid, rectosigmoid, or rectum via peritoneal seeding/metastasis is consistent with T2b disease and would correlate with code 450 (pelvic sites), not codes 600-750 (abdominal sites). Those codes only correlate with T3 and greater disease (i.e., peritoneal seeding/metastasis of the abdomen). |
Thank you for bringing this issue to our attention. Rectosigmoid and Sigmoid Colon belong in Note 3 and not Note 6 for the following EOD schemas: Fallopian Tube, Ovary, and Primary Peritoneal Carcinoma. Rectosigmoid and sigmoid colon will be removed as separate listings from Note 6. The only mention in Note 6 will be: Intestine, large (except rectum, rectosigmoid, and sigmoid colon) This change will be made for the next update. |

20190014 | Reportability--Behavior: Is reportable if it shows invasion or microinvasion pathologically? See Discussion. |
The SEER Manual states, Generally, this rule is invoking the Matrix principle in the ICD-O-3. We are aware this is not the same as a VIN III or an adenoma with microinvasion because those tumors have a valid histology code listed in the ICD-O-3. The terms or or do not have a valid ICD-O-3 code to apply the Matrix principle. If severe dysplasia is felt to be consistent with a carcinoma in situ, then a severe dysplasia with microinvasion would be reportable as 8010/3. But in the U.S., we do not accession severe dysplasia as equivalent to carcinoma in situ unless the pathologist also states the severe dysplasia is equivalent to carcinoma in situ (e.g., ). |
Severe dysplasia alone is not reportable. No further instructions apply because this term is not reportable.In order to use the instructions for behavior, you must first have a reportable neoplasm. If carcinoma in situ is mentioned and there is microinvasion, code the behavior as /3 according to the instructions in the SEER manual. You are correct, do not accession severe dysplasia as equivalent to carcinoma in situ unless the pathologist also states the severe dysplasia is equivalent to carcinoma in situ (e.g., ). |
