20190013 | Laterality--Head and Neck: Were the topography codes C090 and C091 intentionally left off of the Sites for Which Laterality Codes Must Be Recorded table in the 2018 SEER Manual? The codes were also removed from Table 10 in the 2018 Solid Tumor Rules for Head and Neck but appear under coding instructions 1b. and 6b. in the manual. |
Thank you for bringing this to our attention. C090 and C091 were intentionally removed from the list of sites for which laterality must be coded. They should have also been removed from coding instructions 1b and 6b. We will make that correction in the next version of the manual. |

20190009 | First Course Treatment/Surgery of Primary Site--Breast: How is "Goldilocks," also referred to as oncoplastic reconstruction, in the surgery section for breast cancer patients coded? |
Code Goldilocks mastectomy in Surgery of Primary Site. Breast surgery code 30 seems to be the best available choice for "Goldilocks" mastectomy. It is essentially a skin-sparing mastectomy with breast reconstruction. The choice between code 30 and codes in the 40-49 range depends on the extent of the breast removal. Review the operative report carefully and assign the code the best reflects the extent of the breast removal. |

20190033 | Update to current manual/Neoadjuvant therapy/Pathologic tumor size--Breast: When a patient with invasive breast cancer is started on neoadjuvant therapy and at surgery is found to have only residual in-situ disease, do we record the size of the in-situ tumor for Pathologic Tumor Size? See Discussion. |
I understand that we are to record the Clinical Tumor Size in Tumor Size Summary because of the neoadjuvant therapy, but the SEER manual does not address what to record in the Pathologic Tumor Size after neoadjuvant therapy. Would we record 999 or the size of the in-situ tumor in the Pathologic Tumor Size field? Will there ever be a new data item added or changes to this current data item? By recording the Patholigic Tumor Size this way, there currently will not be any way to compare tumor size clinically versus after neoadjuvant therapy and assessing the response. |
Note: this is an update to the 2018 SEER manual. Assign 999 in Pathologic Tumor Size when neoadjuvant therapy has been administered. We can explore the possibility of another data item in the future. |

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) |

20190006 | MP/H Rules/Multiple primaries--Breast: Please confirm Multiple Primaries/Histology Breast Rule M8 applies in this 2017 case. The surgical resection is >60 days past the biopsy date but is it possible treatment plans for breast could span >60 days and this is one primary? See Discussion. |

Abstract a single breast primary. Apply MP/H Rule M3 as this is a single tumor identified in the biopsy at 8 o'clock and at the same location in the mastectomy specimen. Code the behavior as invasive according to rule H9. The first course of therapy ends when the documented treatment plan is completed, no matter how long, unless there is progression, recurrence, or treatment failure. |

20190081 | Race: How is race coded for a patient who self-reports as white? In the Family History portion of the genetics consult, it states the maternal family is of mixed European and Cherokee descent; the paternal side is of mixed German/mixed European descent. Is race coded as Race 1: 03-American Indian and Race 2: 01-White, or as 01-White according to self-report by the patient? |
Self-reported information is the highest priority for coding race. That is because the race information for the U.S. population comes from census data and that information is self-reported. For national cancer statistics, in order for the numerator (cancer cases) and the denominator (population) to be comparable, use self-reported race information whenever it is available. We will add this clarification to the SEER manual. |

20190097 | Solid Tumor Rules (2018)/Multiple primaries--Lung: How many primaries are there and what M rules apply for multiple lung histologies in the left lower lobe (LLL) and right upper lobe (RUL) of the lungs? See Discussion. |
There is one tumor in the left lung that is acinar adenocarcinoma, 8551/3, and two tumors in the right lung, one of which is 8551/3 and a separate one that is mucinous adenocarcinoma 8253/3. 3/21/18- left robotic video assisted thoracoscopy with left lower lobe lobectomy: 2.5 cm adenocarcinoma, acinar predominant, margins negative 11/3/18- right upper lobe lobectomy: invasive mucinous adenocarcinoma, 1.7 cm, invasive adenocarcinoma, acinar predominant, 0.6 cm, margins negative If you start by comparing the 8551/3 left lung tumor to the 8253/3 right lung tumor, M6 applies and these would be separate primaries (seq 01 and seq 02). How would we handle the third tumor, 8551/3, in the right lung? Seq 01: 3/21/18- left lung primary 8551/3 Seq 02: 11/3/18- right lung primary 8253/3 Is the right lung tumor 8551/3 a third primary, and if so, which M rule applies? I cannot find a rule that seems to fit completely. Rule M6 may apply if you were comparing the right 8551/3 tumor to the seq 02 8253/3 tumor. But how would you know to use the seq 02 histology code 8253/3 or seq 01 histology code 8551/3 for the comparison? I think M9 was designed for situations where you have multiple tumors involving both lungs but they didn't biopsy all of them. Is that correct? If so, then we would be able to bypass M9. Would M11 apply since we already took care of two of the tumors with rule M6? If M11 doesn't apply, it seems like you would get to M14. |
Abstract two primaries applying Rules M6 and M9 s follows. First, assign a histology for each tumor. --LLL adenocarcinoma, acinar predominant 8551/3 --RUL invasive mucinous adenocarcinoma 8253/3 --RUL invasive adenocarcinoma, acinar predominant 8551/3 For the RUL, this is two primaries according to Rule M6, to subtypes in Column 3 of the histology table. For the LLL and RUL, this represents the same primary as these are the same histology according to Rule M9. |

20190025 | 2018 Solid Tumor Rules/Histology--Colon: What is the histology code of a diagnosis of well differentiated neuroendocrine tumor (NET), grade 2 of the appendix? See Discussion. |
SINQ 20160023 and the Solid Tumor Rules indicate NET G1 (or well differentiated NET) is coded as 8240 and NET G2 is coded as 8249. Clarification regarding grade coding in the CAnswer Forum indicates well differentiated neuroendocrine tumor refers to the histologic type, and not the grade. Therefore, the term well differentiated is ignored for the purpose of grade coding. Neither of these sources clarifies how to code histology for a tumor diagnosed as well differentiated neuroendocrine tumor, grade 2. |
Assign histology code 8249 for histology described as well differentiated NET G2. A synonym for NET of the appendix includes well-differentiated endocrine tumor/carcinoma according to WHO Classification of Tumors of the Digestive System, 4th edition. "Well differentiated" could apply to either NET G1 or NET G2. |

20190103 | Solid Tumor Rules/Multiple primaries--Brain and CNS: What M rule applies to a clinically diagnosed right-sided parietal meningioma undergoing active surveillance, followed by a left-sided frontal anaplastic oligodendroglioma? See Discussion. |
The patient has two, separate, non-contiguous tumors. One tumor is a benign meningioma and the other is a malignant oligodendroglioma. The original plan was not to treat the asymptomatic meningioma. However, after worsening symptoms, imaging and resection proved a separate left frontal lobe malignant tumor. Rule M5 is the only M Rule in the Malignant CNS Multiple Primary Rules, Multiple Tumors module that addresses separate non-malignant and malignant tumors. This rule provides only two criteria to follow when a malignant tumor follows a non-malignant tumor. The first criteria (for non-malignant tumor followed by malignant tumor) states: --Patient had a resection of the non-malignant tumor (not the same tumor) OR --It is unknown/not documented if the patient had a resection. This patient did not have a resection of the original, separate, non-malignant tumor, but the treatment plan was known to not include a resection. Should Rule M5 also apply to cases where the patient never had treatment planned for the separate non-malignant tumor? |
Apply 2018 Malignant CNS Solid Tumor Rule M5 and abstract multiple primaries when there are multiple CNS tumors, one of which is malignant /3 and the other is non-malignant /0 or /1. According to Note 3, a non-malignant CNS tumor and a malignant CNS tumor are always multiple primaries (timing and primary sites are irrelevant). Prepare two abstracts; one for the non-malignant and another for the malignant tumor. |

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. |
