20190108 | Primary site--Breast: how is subsite coded for a breast cancer when it is described as central portion between 1-3:00 or central portion at 12:00? |
See the SEER coding guidelines for breast, https://seer.cancer.gov/manuals/2018/AppendixC/Coding_Guidelines_Breast_2018.pdf Generally, codes C502 - C505 are preferred over C501. C501 would be preferred over C508. Apply these general guidelines when there is no other way to determine the subsite using the available medical documentation. Table 1, Primary Site codes, in the breast solid tumor rules also provide helpful information for coding site. |

20190051 | Update to current manual/Solid Tumor Rules (2018)/Histology--Lung: What is the histology code and what M Rule applies when there are multiple specific subtypes identified using various equivalent lung terms but only one is stated to be predominant? See Discussion. |
Example: Lung resection final diagnosis is Lung adenocarcinoma, see Summary Cancer Data, and the Summary Cancer Data (CAP Synoptic Report) states Histologic type: Invasive adenocarcinoma, solid predominant. Other Subtypes Present: 20% acinar and <5% micropapillary components. Instruction 1B and Note 1 for Coding Multiple Histologies (Lung Histology Rules) indicates type, subtype, component, and predominantly are all terms that may be used to code the most specific histology. In this case, the multiple specific histologies were documented using all of those terms. Note 2 for instruction 1B states predominantly describes the greatest amount of tumor and when it is used for the listed subtypes of adenocarcinoma, that subtype should be coded. However, Note 2 does not indicate that the other subtypes are ignored when one is identified to be predominant and the others are identified as subtype or component only. |
Code to invasive adenocarcinoma, solid predominant (8230/3), based on the example, using Lung Solid Tumor Rules Coding Multiple Histologies instruction #1 that says to code the specific histology where the most specific histology may be described as component, majority/majority of, or predominantly, in this case, 75%. Apply Rule M2 as this appears to be a single tumor with multiple histologies based on the information provided. The rules will be updated to add a new H rule and to reviseTable 2 when two or more histologies described as predominant are present. |

20190045 | Solid Tumor Rules (2018)/Multiple Primaries--Head & Neck: How many primaries are accessioned and what M Rule applies when a patient is diagnosed with a right lateral tongue (C023) tumor in 2016 that was verrucous carcinoma (8051), followed by a new left tongue border (C021) tumor in 2019 that was squamous cell carcinoma, NOS (8070)? See Discussion. |
According to the Multiple Primaries/Histology Rules in place at the time of the 2016 diagnosis, verrucous carcinoma was listed as a specific type of squamous carcinoma (Chart 1). However, in the current Solid Tumor Rules, verrucous carcinoma is not listed in Table 4 (Tumors of Oral Cavity and Mobile Tongue) either as a specific histology or as a specific subtype/variant of squamous carcinoma. The only subtype/variant listed for these sites is acantholytic squamous cell carcinoma (8075). Verrucous carcinoma is not listed in Table 4, making it unclear if it should be a different histology for these specified sites. However, verrucous carcinoma is listed as a specific subtype/variant of squamous carcinoma for other sites (e.g., Table 3). |
Accession a single primary based on the 2018 Head and Neck Solid Tumor Rule M13 as none of the other rules apply to the situation. Not all histology codes are contained in the tables in the Solid Tumor Rules as they list the more common histologies. Verrucous carcinoma is a subtype of squamous cell carcinoma according to Table 3 of the Rules. Solid Tumor rule tables are based on 4th Ed WHO Blue Books. Verrucous SCC is not included in oral cavity/mobile tongue chapter. |

20190107 | First Course Treatment/Chemotherapy--Colon: Is maintenance therapy coded as part of the first course of treatment or as part of subsequent course of treatment? |
Patient was diagnosed with Stage IV colon cancer (liver metstasiss) and started on Folfox with Avastin. The medical oncologist decided to continue maintenance treatment with Xeloda and Avastin. Per Colon NCCN Guidelines Version 3.2019, interest in the use of maintenance therapy approach after first-line treatment of unresectable, metastatic colorectal cancer is growing. In general, this approach involves intensive first-line therapy, followed by less intensive therapy until progression in patients with good response to initial treatment. Colon Therapy 5/1/18 Colonoscopy biopsy: mod diff colon adenoca, MMR proficient, BRAF wild type 5/5/18 Liver biopsy: mets from colon cancer 6/18/18 " 11/20/2018 Med Onc: started 12 cycles Chemo - Folfox (Fluorouracil, leucovorin, Oxaliplatin) with Avastin 11/28/18 CT Pelvis: continued improvement in the liver mets; no residual tumor involving colon; no new mas or adenopathy in the chest, abdomen or pelvis 12/02/18 Med Onc follow up: Pt had tremendous response to chemotherapy and Avastin, cancer is not curable. Is amenable to maintenance therapy with Xeloda and Avastin; also amenable to descending colectomy in the future 1/7/19 Med Onc: starting maintenance treatment Xeloda + Avastin. |
Code the maintenance therapy as first course when the maintenance therapy includes at least one of the drugs from the original treatment. Use text fields to record the details. |

20190074 | First course treatment/Scope of Reg LN Surgery--Breast: How is Scope of Regional Lymph Node Surgery coded when there is a sentinel lymph node biopsy (SLNBx) and intra-mammary nodes removed for a single primary? See Discussion. |
Example: Operative report documents a left breast skin sparing mastectomy and sentinel node biopsy procedure. Pathology report lists left axillary sentinel nodes in specimen A) with 0/2 nodes positive, and left breast mastectomy without axilla in specimen B) yielding an additional 0/2 intramammary nodes positive. Would the Scope of Regional Node Surgery be coded as 2 (SLN biopsy) to capture the intent of the sentinel node procedure only, or 6 (code 2 + 4) to capture the actual type and number of nodes removed? SEER Coding and Staging Manual includes Scope of Regional Lymph Node Surgery instruction 4.b. which mentions assigning code 4 to intra-organ node removal. Similarly, there is instruction for coding SLN biopsy as code 2 and SLN biopsy with axillary dissection at the same time (code 6) or during separate procedures (code 7). However, it is not clear this combination code is how we should also capture an incidental intra-organ node removal. |
Revised answer 07/11/2023 Assign code 6, Sentinel node biopsy and code 3, 4, or 5 at same time or timing not noted. There were two sentinel lymph nodes removed (code 2) plus two intramammary nodes removed in a separate specimen from the mastectomy (code 4). Assign code 6 when nodes are removed from a sentinel lymph node procedure at the same time as removal of intra-organ lymph nodes which were not part of the sentinel lymph node procedure. |

20190049 | Lymph nodes/Melanoma: Is a single axillary lymph node regional or distant for a patient diagnosed in 2018 with metastatic melanoma to the brain found via imaging. The staging procedure was an single axillary lymph node excision that was positive for metastatic melanoma. The exact site of the primary was never determined; the primary site is coded to C449. See Discussion. |
The patient was diagnosed in 2018 with met melanoma to the brain found via imaging. The staging procedure was a single axillary lymph node excision which was positive for metastatic melanoma. The exact site of the primary was never determined and the site code is C449. Is the axillary lymph node regional or distant? This affects how I code regional lymph nodes positive, regional lymph nodes examined, and scope of regional lymph node surgery or surgical procedure other site. Similar question was asked in the past (question # 20091101) but I have not found this question restated since the 2018 changes and just want to verify this is still what we are to do. |
Lymph node mets from a melanoma of unknown primary site are presumed to be regional if the lymph node mets are confined to one area, as they are in this case. We are assuming there are no previous melanoma diagnoses for this patient. The workup should include examination of the skin areas that drain to the axillary area. |

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. |

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. |

20190040 | Reportability--Heme & Lymphoid Neoplasms: Is peripheral blood with a diagnosis of monoclonal B-cell lymphocytosis (MBL) with chronic lymphocytic leukemia (CLL) phenotype reportable for any year? See Discussion. |
SINQ 20180050 and 20130041 appear to have conflicting answers regarding the reportability of MBL with CLL (immuno)phenotype. While the question content of SINQ 20180050 does not reference the CLL phenotype, it is included in the Discussion as part of the oncologist's assessment. The answer does not address the clinical diagnosis of MBL with CLL-phenotype and simply states that monoclonal B-cell lymphocytosis is not reportable. SINQ 20130041 does include the CLL phenotype information in the primary question and it is expanded on in the discussion as present in peripheral blood. Based on that information, the answer is that it should be reportable and coded as CLL (9823/3). |
The description in the question is for 9823/1 per WHO blue book 2016. This description and code are not reportable. We will review the other SINQ questions and revise if necessary. |

20190047 | Reportability/Liver: If on imaging, there is no statement of the Liver Imaging Reporting and Data System (LI-RADS) score but there is reference that a lesion is in the Organ Procurement and Transplantation Network (OPTN) 5 category, is hepatocellular carcinoma (HCC) reportable based on the OPTN 5 classification? See Discussion. |
SINQ 20160008 discusses the reportabilty and diagnosis date for liver primaries where imaging references the LI-RADS category as LR-5 or LR-5V. The 2018 SEER Coding and Staging Manual, Appendix E Reportable Example #16, demonstrates this concept. According to the LI-RADS categories a value of 5 is "definitely HCC" and is concordant with OPTN 5. Often we see only the OPTN categorization. |
Report HCC based on the OPTN class of 5. OPTN class 5 indicates that a nodule meets radiologic criteria for HCC. Be sure to document in text fields. |
