20230001 | Solid Tumor Rules/Multiple Primaries--Lung: How many primaries should be reported when two separate squamous cell carcinoma (SCC) tumors, one in the left upper lobe (LUL) and one in the right lower lobe (RLL), are diagnosed? The tumors are separated by an interval occurring right hilar lymph node biopsy proving metastatic pulmonary adenocarcinoma without a clear description of a corresponding interval occurring lung tumor. See Discussion. |
The patient was diagnosed with a biopsy-proven 12/2020 LUL SCC treated with radiation only, followed by a right hilar lymph node biopsy in 07/2022, that proved “metastatic pulmonary adenocarcinoma” per pathology and treated with radiation, followed by a biopsy-proven 12/2022 RLL SCC to be treated with immunotherapy only. The imaging never definitively identified a lung tumor that can be assumed to be a primary adenocarcinoma tumor. In 06/2022, a PET scan only described a “strongly PET positive Rt inferior hilar LN vs infrahilar pulmonary mass,” as well as the subsequently biopsy-proven SCC in the RLL (12/2022 SCC primary). The biopsy path indicates this was a right hilar lymph node metastasis and does not indicate this is an infrahilar pulmonary mass. No other PET positive pulmonary lesions were seen at the time. The oncologist’s assessment indicates the right hilar node was the only positive finding on the biopsy, and it was unclear if this right hilar node metastasis was from the left lung or if the primary was “not detectable.” The oncologist summarized this as a LUL lung lesion radiated for SCC, a right hilar lesion radiated for adenocarcinoma, and a RLL lung lesion on pathology found to be SCC. Should the interval occurring metastatic adenocarcinoma be accessioned as a separate lung, NOS primary based on the histology difference? While the Solid Tumor Rules do not apply to metastasis, the oncologist did treat these three malignancies separately and does not indicate the hilar lymph node metastasis was felt to be from either SCC primary. |
Abstract three primaries based on this scenario. 1 – 2020, SCC LUL lung 2 – 2022, Adenocarcinoma lung, described as metastatic pulmonary, based on biopsy of right hilar node (Rule M8) 3 – 2022, SCC RLL lung (Rule M11) |

20230037 | Reportability/Histology--Gallbladder: Is intracholecystic papillary-tubular neoplasm (ICPN) with extensive high grade dysplasia of the gallbladder reportable? |
Report intracholecystic papillary neoplasm (ICPN) with high-grade dysplasia (8503/2) of the gallbladder. |

20230069 | First Course Treatment/Immunotherapy--Colon: Is infliximab cancer directed treatment? See Discussion. |
While SEER*Rx does indicate infliximab should be coded as biological response modifier (BRM)/Immunotherapy, the manufacturer website for this medication indicates it is given for: Crohn’s disease, ulcerative colitis, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and plaque psoriasis. In addition, SEER*Rx does not indicate which primary sites this treatment may be given for. If it is indeed cancer directed treatment, can the typical primary sites be added for clarity? Case example: Patient is diagnosed with colorectal cancer and also has an existing diagnosis of Crohn’s disease; received surgery and FOLFOX6, as well as infliximab. There was no statement of what disease the infliximab was given to treat. |
infliximab is not cancer-directed treatment. This drug was last updated by the FDA 2/22/2023 with additional information on its approval to treat non-malignant neoplasms. To date, the FDA has not approved it for use in colon cancer. This drug was intially developed to treat colon cancer; however, found to be ineffective treating cancer. |

20230011 | Solid Tumor Rules/Multiple Primaries--Prostate: How many primaries are accessioned when a 2023 liver biopsy diagnosed metastatic small cell carcinoma (SmCC) of the prostate following a 2018 radical prostatectomy treated diagnosis of prostatic adenocarcinoma? See Discussion. |
SINQs 20190083, 20180088, and 20130221 all indicate diagnoses of prostate adenocarcinoma, followed by a diagnosis of metastatic small cell carcinoma of the prostate are separate primaries because these are distinctly different histologies. Does this logic still apply for 2023 and later since Rule M4 was added to the Other Sites M Rules? Rule M4 states, “Abstract multiple primaries when the patient has a subsequent small cell carcinoma of the prostate more than 1 year following a diagnosis of acinar adenocarcinoma and/or subtype/variant of acinar adenocarcinoma of prostate.” This patient has a 2018 diagnosis of prostate adenocarcinoma treated with radical prostatectomy, followed by a 2023 diagnosis of metastatic small cell carcinoma of the prostate diagnosed on a liver metastasis core biopsy. Rule M4 does not indicate whether it applies to subsequent biopsy confirmed metastatic tumor only. When a diagnosis of small cell carcinoma follows a diagnosis of prostatic adenocarcinoma, it is almost always confirmed in metastatic sites rather than in the primary site. Does the logic in the referenced SINQs above still apply for Rule M4? |
Accession two primaries, adenocarcinoma (8140/3) of the prostate and SmCC (8041/3) of the prostate using Rule M4 of the current Other Sites Solid Tumor Rules. The guidance in the aforementioned SINQ entries still applies with the additional criteria of being diagnosed more than one year following the diagnosis of acinar adenocarcinoma, or subtype, of the prostate as stated in Rule M4 of the updated 2023 rules. Small cell carcinomas of the prostate are often diagnosed on follow-up TURP/biopsies; however, if a patient had a previous radical prostatectomy, the small cell carcinoma would be identified in a metstatic site and would still be a new prostate primary. This includes biopsy confirmed metastatic tumors only. It remains important to capture the two distinct histology types. |

20230003 | SEER Manual/Reportability--Ambiguous Terminology: Please clarify the reportability and relevant date ranges of the following ambiguous terminology: almost certainly, most certainly, and malignant until proven otherwise. See Discussion. |
SINQ 20180104 indicates, in the absence of further info, the terms “almost certainly” and “until proven otherwise” are NOT reportable. There is no date range provided for this answer. SINQ 20200027 indicates, in the absence of further info, the term “most certainly” IS reportable. There is no date range provided for this answer. SEER Program Coding and Staging Manual 2022 indicates, in the absence of further info, the terms “until proven otherwise” and “most certainly” ARE reportable. Essentially, we are hoping for an update of SINQ 20180104 due to 2022 reportability change. Clarification to the equivalence of “almost certainly” and “most certainly” would also be helpful. |
Use the ambiguous terminology list as a guide in the absence of additional information after reviewing all available information and consulting the physician who diagnosed and/or staged the tumor. Equivalent to "Diagnostic for" malignancy or reportable diagnosis
Not Equivalent to "Diagnostic for" malignancy or reportable diagnosis
We will update SINQ 20180104. |

20230061 | EOD (2018)/EOD Primary Tumor--Prostate: How is Extent of Disease (EOD) Prostate Pathologic Extension coded when no residual cancer is found? See Discussion. |
Patient was diagnosed with a pT1c prostate cancer in 2022. Patient was then treated with radical prostatectomy. No residual disease was found. Would the correct EOD prostate path extension code be 999 based on Note 8 (code 999 when radical prostatectomy is performed, but there is no information on the extension); or, would we use code 300 (confined to prostate) because the data item "…is used to assign pT category for prostate cancer based on radical prostatectomy specimens" and we know it was limited to the prostate because no residual was found? |
Assign code 300 for EOD Prostate Pathologic Extension. In this scenario, the patient has a localized cancer confirmed by radical prostatectomy; the needle core biopsies likely removed all the cancer. Unlike prostate, other sites’ extension information is collected in EOD Primary Tumor, as seen commonly with breast tumors where the results from the surgical resection are recorded with tumor confined to primary site. |

20230048 | Solid Tumor Rules/Histology--Uterine Corpus: How is histology coded for an epithelioid and myxoid leiomyosarcoma of the myometrium? See Discussion. |
Patient had a total abdominal hysterectomy-bilateral salpingo-oophorectomy performed in January 2023 with final diagnosis of myxoid and epithelioid leiomyosarcoma. Diagnosis comment states: The tumor is 15 cm per report. It grows in nests and poorly formed interanastomosing trabeculae and cords that are separated by abundant myxoid background. The cells have an epithelioid morphology with eosinophilic cytoplasm, large nuclei, and very prominent nucleoli. The mitotic activity is overall low ranging from 1 to 3/10 HPFs. Immunohistochemical stains performed at the outside hospital showed diffuse positivity for SMA, desmin, caldesmon, and PR. They are negative for CD10, claudin-4, calretinin, HBM45, MART1 (rare weakly positive cells), PANCK, and SOX10. This immunohistochemical profile supports a smooth muscle derivation of this neoplasm. As this tumor is extensively myxoid, diagnostic criteria differ from the spindle cell leiomyosarcoma. Per Solid Tumor Rules Other Sites, Table 16: Uterine Corpus Histologies, Epithelioid Leiomyosarcoma (8891/3) and Myxoid Leiomyosarcoma (8896/3) are both subtypes of Sarcoma, NOS (8800/3). Per Rule H21, use a combination code when there are multiple specific histologies AND the combination is listed in Table 2 OR there are coding instructions for the combination in the applicable histology Tables 3-21 OR you receive a combination code from Ask A SEER Registrar. Since there is no combination listed in Table 2 and there is no instruction for the combination in Table 16, how should the histology be coded for this tumor? |
Assign code 8891/3 (epithelioid leiomyosarcoma) as cells were described as have an epithelioid morphology; whereas, myxoid was used as a descriptive term and not a specific histologic type. |

20230057 | EOD (2018)/EOD Regional Nodes--Thyroid: How is Extent of Disease (EOD) Regional Nodes coded for thyroid primary with cervical lymph nodes containing psammomatous calcifications (psammoma bodies) but negative for metastatic tumor cells? See Discussion. |
The AJCC 8th edition confirms that the identification of psammomatous calcifications within a cervical lymph node is metastatic disease. Example: Patient had a thyroid lobectomy and level VI neck node excision in August 2022. The final diagnosis is multifocal papillary carcinoma of the thyroid, as well as rare psammomatous calcifications only in the resected node. The pathologist notes that “psammoma bodies only” in lymph nodes is not well defined, and while indolent, they do indicate capacity for lymphatic spread and are pN1a. Should thyroid primaries with cervical node psammomatous calcifications get captured in EOD Regional Nodes category as it is in the AJCC pN staging? |
Assign EOD Regional Nodes code 300 for Psammoma bodies within a cervical lymph node that are microscopically confirmed. A clarifying note for the Thyroid Schema will be included in the 2025 EOD updates. |

20230073 | First Course Treatment/Surgery of Primary Site--Liver/Intrahepatic Bile Ducts: For a liver/intrahepatic bile duct primary, is an alcohol embolization the same thing as a percutaneous ethanol injection (PEI)? See Discussion. |
For C220-C221 primaries, Surgery of Primary Site includes code A150 for Alcohol tumor destruction (percutaneous ethanol injection/intratumoral injection of alcohol/alcohol ablation). The SEER and STORE manuals also indicate that alcohol embolization should be coded as Other Therapy, code 1. We are trying to determine whether alcohol embolization should be coded under Surgery of Primary Site or Other Therapy. |
Code alcohol ablation under Surgery of Primary Site 2023. Code alcohol embolization as Other Therapy when tumor embolization is performed using alcohol as the embolizing agent. Alcohol ablation, also known as an ultrasound-guided percutaneous ethanol injection (PEI); is treatment that involves injecting concentrated alcohol directly into the tumor. Embolization uses special techniques to close off blood flow by introducing special medications or using other techniques designed to block blood vessels. Types of embolization are arterial embolization as with alcohol (ethanol), chemoembolization, and radioembolization. Refer to the current SEER Program Coding and Staging Manual when assigning surgery and embolization procedures. |

20230056 | Reportability/Histology--Heme and Lymphoid Neoplasms: What is the histology code for nodular lymphocyte predominant B cell lymphoma that is never called Hodgkin lymphoma? Is it acceptable to record the histology code for nodular lymphocyte predominant Hodgkin lymphoma, (9659/3)? See Discussion. |
Patient has a history of human immunodeficiency virus and diffuse large B cell lymphoma diagnosed in 2012, and is status/post systemic therapy and in remission since completing first course treatment. In 2022, the patient has imaging suspicious for recurrence. A biopsy of a deep left cervical lymph node showed atypical lymphoid infiltrate with the comment: “This is a challenging case. The constellation of findings is most in keeping with early / focal and subtle involvement by a nodular lymphocyte predominant B-cell lymphoma. We find no evidence of involvement by a diffuse large B-cell lymphoma.” The managing physician later states, “Cervical lymph node biopsy (06/2022) was consistent with nodular lymphocyte predominant B cell lymphoma.” |
According to the 5th edition WHO Blue Book for Hematopoietic Neoplasms, Beta Version, (not released yet), nodular lymphocyte predominant B-cell lymphoma is an alternate name for 9659/3. We will update the Heme database once the 5th edition is released in print. |
