20230004 | SEER Manual/Laterality--Kaposi Sarcoma: If both arms are involved with Kaposi sarcoma and no other sites, how is laterality coded? See Discussion. |
Per Solid Tumor Manual Other Sites Rule M6, despite the number of areas of involvement, any presentation of Kaposi sarcoma is always a single primary. The primary site is skin using the Kaposi Sarcoma for All Sites Coding Guidelines (Appendix C, 2023 SEER Manual). Does SEER Program Coding and Staging Manual Laterality Coding Instruction #4 preclude the use of code 4 [Bilateral involvement at time of diagnosis...] if a patient presents with KS involvement of only both arms or only both sides of the face? |
Assign Laterality code 4 (Bilateral involvement at time of diagnosis, lateral origin unknown for a single primary) in the situations you describe. Skin of upper limb and shoulder and Skin of other and unspecific parts of the face are listed as paired organs in the table Sites for Which Laterality Must Be Recorded In the 2023 SEER Manual. |

20230040 | First Course Treatment/Hormone Therapy--Prostate: Is Lupron first course therapy in a patient who initially elected active surveillance for prostate cancer and then consented to treatment with Lupron? See Discussion. |
in March, the patient with stage cT1c, Gleason grade 7, prostate cancer elected active surveillance. In April, the patient consented to treatment with Lupron. There was no evidence of disease progression. According to the rules on page 161 of the 2023 SEER manual, we think the answer is yes, but the reporting hospital states that this is second course therapy. |
Code Lupron as second course therapy and code active surveillance as first course therapy in this scenario. The 2023 SEER Manual states to code all treatment data items to 0 or 00 (Not done) when the physician opts for active surveillance, deferred therapy, expectant management, or watchful waiting. Assign code 2 to Treatment Status. Active surveillance is not the same as "refusing treatment." Active surveillance is a valid option offered to the patient. The patient chose this option and later changed their mind. This is not a refusal of recommended treatment. Document all the details in the appropriate treatment text fields. |

20230012 | Solid Tumor Rules/Multiple Primaries--Prostate: How many primaries are accessioned when a 06/2022 diagnosis of prostate adenocarcinoma is followed less than one year later by a 01/2023 diagnosis of small cell carcinoma (SmCC)? See Discussion. |
Rule M4 was added to the Other Sites M Rules to address diagnoses of small cell carcinoma following prostate adenocarcinoma, but Rule M4 states the diagnoses must be greater than one year apart. In this situation, the diagnoses were less than one year apart and one must continue through the M Rules. The next M Rule that applies Rule M18: “Abstract multiple primaries when separate/non-contiguous tumors are on multiple rows in Table 2-21 in the Equivalent Terms and Definitions. Timing is irrelevant.” If one were to STOP at the first rule that applies, one would stop at Rule M18 which confirms the prostatic adenocarcinoma and small cell carcinoma are separate primaries, regardless of timing. If these are not to be accessioned as multiple primaries, does an Exception need to be added to M18? |
Assuming the smal cell is a seperate tumor, accession two primaries, adenocarcinoma (8140/3) of the prostate and SmCC (8041/3) of the prostate using Rule M18 of the current Other Sites Solid Tumor Rules. As these two tumors are less than a year apart, Rule M4 does not apply; however, Rule 18 does apply as these are two distinct histology types. It takes time for an acinar tumor to transform into the small cell and it is usually triggered by hormone and/or radiaiton treatment. |

20230063 | EOD 2018/EOD Regional Nodes--Melanoma: Can central cancer registries code Extent of Disease (EOD) Regional Nodes as 000 based on Breslow’s depth and/or Clark’s Level (per EOD and/or Summary Stage) from a melanoma pathology only report with a localized tumor and no information on regional lymph nodes or mets. See Discussion. |
Based on the EOD General instructions for accessible sites, the following three requirements must be met a. There is no mention of regional lymph node involvement in the physical examination, pre-treatment diagnostic testing, or surgical exploration; b. The patient has localized disease; c. The patient receives what would be the standard treatment to the primary site (treatment appropriate to the stage of disease as determined by the physician), or patient is offered usual treatment but refuses it. As a central registry, we receive a lot of melanoma path reports but never receive an abstract since the patients are seen at a dermatology office that does not report to the central registry. In these scenarios, we have both the diagnosis and wide excision or Mohs surgery from which we create a consolidated record. It is not often that lymph nodes are removed which indicates there were no palpable nodes. Since the Breslow’s and Clark’s level allow for summary staging, is it possible to have central registry guidelines that allow for coding lymph nodes other than 999? The path reports meet two of the three criteria. Is there any new literature that supports coding lymph nodes 000 based on a Clark’s level or Breslow measure providing the patient has a wide excision? |
Assign 000 for EOD Regional Nodes when you have a pathology only report with a localized tumor based on Breslow’s depth and/or Clark’s Level (per EOD and/or Summary Stage) and no information on regional lymph nodes or mets. When the tumor is noted to be regional or distant based on Breslow’s Depth and/or Clark’s based on the definitions in EOD and/or Summary Stage, do not assume that the nodes are negative and assign 999. Clarification will be added to the EOD manual. |

20230045 | Reportability/Histology--Thyroid: Is a diagnosis of “angioinvasive oncocytic thyroid neoplasm with features worrisome for a poorly differentiated oncocytic carcinoma” reportable if the diagnosis comment states, additional immunostains were performed which demonstrate the carcinoma cells are positive for thyroglobulin and negative for calcitonin? See Discussion. |
Patient had a right thyroid lobectomy on 12/2022, with initial diagnosis of “thyroid carcinoma pending expert consultation for definitive classification.” The slide review documented in the addendum shows a final diagnosis of “Angioinvasive oncocytic thyroid neoplasm, see comment.” The subsequent comment states, “I would classify this lesion as an angioinvasive oncocytic thyroid neoplasm with features worrisome for a poorly differentiated oncocytic carcinoma.” The comment goes on to state, “Additional immunostains were performed which demonstrate the carcinoma cells are positive for thyroglobulin and negative for calcitonin. The diagnosis remains unchanged.” |
Do not report angioinvasive oncocytic thyroid neoplasm with features worrisome for a poorly differentiated oncocytic carcinoma based on the final, unchanged diagnosis. Worrisome is not a reportable ambiguous terminology. |

20230020 | First Course Treatment/Reason for No Surgery of Primary Site: How should Reason for No Surgery of Primary Site be coded for cases when surgery was planned but aborted due to extent of disease seen during planned procedure? See Discussion. |
Lung abnormality on imaging prompted diagnosis on subsequent biopsy and clinical staging was documented as cT1b N0 M0. There was an attempt at resection, but the patient was found to have chest wall involvement and the procedure was aborted. How would Reason for No Surgery of Primary Site be coded in these types of scenarios when the surgery is aborted and the treatment plan changes due to the extension seen during surgery? |
For the example provided: For 2023 cases and forward, if no part of the surgery was performed, code Surgery of Primary Site 2023 (NAACCR Item #1291) as code A000 or B000 (no surgical procedure of the primary site). Code Reason for No Surgery of Primary Site (NAACCR Item #1340) as code 2 (surgery of the primary site was not recommended/performed because it was contraindicated due to patient risk factors (comorbid conditions, advanced age, progression of tumor prior to planned surgery, etc.). In contrast, if any part of the surgery was performed, assign the Surgery of Primary Site 2023 (NAACCR Item #1291) code that best reflects the extent of the surgery performed. Code Reason for No Surgery of Primary Site (NAACCR Item #1340) as code 0 (surgery of the primary site was performed). Use text fields to record the details. For cases prior to 2023, apply the same approach using Surgery of Primary Site (NAACCR Item #1290) instead of Surgery of Primary Site 2023 (NAACCR Item #1291). |

20240026 | Update to Current Manual/Reportability--Pancreas: For cases diagnosed 2024+, is a diagnosis of pancreatic intraepithelial neoplasia II (PanIN II) reportable? If so, how should histology be coded? See Discussion. |
SEER Program Coding and Staging Manual: Reportability – Reportable Diagnosis List indicates pancreatic intraepithelial neoplasia (PanIN II) (C250-C259) is reportable. However, the ICD-O-3.2 lists “Glandular intraepithelial neoplasia, grade II” and “Glandular intraepithelial neoplasia, low grade” as histology code 8148 with behavior of /0 (benign). |
Do not report PanIN II. WHO Classification of Digestive Tumors, 5th edition, now categorizes PanIN into two categories, low grade (8148/0) and high grade (8148/2). PanIN grade I and PanIN grade II are categorized as PanIN low grade; PanIN grade III is categorized as PanIN high grade. We will update the Reportability section of the manual. |

20240004 | Reportability/Histology--Skin: Is a malignant spindle cell neoplasm consistent with atypical fibroxanthoma reportable for cases diagnosed 1/1/2023 and later, after thorough immunohistochemical work-up? See Discussion. |
Appendix E1 in both the 2023 and 2024 SEER Program Coding and Staging Manual (SPCSM) lists these malignant spindle cell neoplasms, consistent with atypical fibroxanthoma, as reportable when other tumors have been ruled out with immunohistochemistry. This contradicts both SINQ 20190102 and the Solid Tumor Rules (STRs) general instructions indicating ambiguous terminology (e.g., “consistent with”) cannot be used to code the more specific histology when there is a NOS (malignant spindle cell neoplasm, 8004/3) and a more specific (malignant atypical fibroxanthoma, 8830/3) histology. These tumors are typically diagnosed and treated in dermatology offices, so further chart review or confirmation by a physician is not possible for central registries. As non-melanoma skin primaries are included in the Other Sites schema, and this schema was updated for cases diagnosed 2023 and later, which instruction applies to 2023+ diagnoses? Should these continue to be collected per Appendix E1 despite the conflict with the STR Manual and SINQ? If these are reportable, should the SINQ and STR Manual be updated to reflect this? Or should these be non-reportable per the STR Manual and SINQ? |
Report malignant spindle cell neoplasms consistent with atypical fibroxanthoma as directed by Appendix E.1 of the 2023 and 2024 versions of the SEER Manual using 8830/3 (fibroxanthoma, malignant). We will update the answer in SINQ 20190102. While the Other Sites Solid Tumor Rules address coding an NOS and specific histology sub-type/variant, this situation is not specifically addressed. We will also review the rules. |

20240016 | Histology/Behavior--Head and Neck: What is the histology code for sinonasal glomangiopericytoma in 2023? See Discussion. |
6/8/2023 A. Left nasal mass: Sinonasal glomangiopericytoma B. Additional left nasal mass: Sinonasal glomangiopericytoma Is this a borderline tumor? I am unable to find in this in the ICD-O-3 purple book or the Head and Neck Solid Tumor Rules. |
Assign histology code 8815/3 per ICD-O-3.2. Sinonasal glomangiopericytoma is also referred to as a sinonasal hemangiopericytoma. Prior to 2021, it was coded as 9150/3. |

20240011 | Solid Tumor Rules/Histology--Other Sites: Other Sites Table 2 (Mixed and Combination Codes) requires site designations; can sites be added? See Discussion. |
There are multiple possible entries (rows) for a tumor with a neuroendocrine component and non-neuroendocrine component, but these rows do not specify which primary sites are applicable. Row 1 (Combined small cell carcinoma, 8045) seems applicable to a prostate primary, but not to a GI primary since GI primaries are now generally referred to as MiNENs (mixed neuroendocrine non-neuroendocrine tumors), but Table 2 does not provide any instructions regarding how to determine the difference between 8045 and 8154 (or 8244). For SEER Workshop Case 03 (mixed prostate case), many users selected 8154 or 8244 as the mixed histology code per Table 2, but these histology codes are not listed as applicable in Table 3 (Prostate Histologies). Per the WHO Blue Books, these histologies are not listed as applicable to the prostate. How are registrars to determine the correct mixed code without site designations, especially if they don't have access to the WHO Blue Book or to a pathologist who may be able to clarify the codes? |
Sites may be added to certain combinations when indicated by ClinCORE review for Cancer PathCHART. Please note some sites were added in the 2024 update as a result of PathCHART review. A newly-formed Solid Tumor Editorial Board and its subgroups are currently working to evaluate the Solid Tumor Manual and make recommendations on ways to improve the structure and formatting of the manual and its content. Follow the rules and instructions in the Other Sites STRs when assigning combination histology codes. Histology Coding Rules Use the Histology Coding Rules when assigning combination codes. Coding Histology Information Use this section that includes the mixed histology (Table 2) and site-specific histology tables (Tables 3-23) for one or more histologies within a single tumor. Do not use this section in place of the Histology Coding Rules. While site-specific histology tables, based on current WHO Classification of Tumors books, have been added to Other Sites STRs, not all site groups have individual histology tables; coding may require the use of ICD-O and updates. The histology tables in Other Sites STRs include additional coding instructions and notes to assign the correct ICD-O code when appropriate. The tables are not meant to be all-inclusive; rather they are intended to address difficult coding situations to facilitate the assignment of the correct histology code. Table 2: Mixed and Combination Codes Instructions Once you have identified the histology terms and have been instructed to use Table 2 by the Histology Coding Rules, compare the terms in the diagnosis to the terms in Column 1. When the terms match, use the combination code listed in Column 2. Use adenocarcinoma mixed subtypes 8255 as a “last resort” code. |
