20240027 | Solid Tumor Rules/Multiple Primaries--Brain and CNS: How many primaries are accessioned when a 2005 diagnosis of glioblastoma multiforme is followed by a 2024 diagnosis of astrocytoma, IDH-mutant, WHO grade 4? See Discussion. |
The patient underwent a gross total resection of the 2005 glioblastoma multiforme (9440/3). The patient was subsequently diagnosed with a 2024 diagnosis of astrocytoma, IDH-mutant, WHO grade 4 (9445/3). Should Rule M13 apply to the new 2024 diagnosis and a new primary be accessioned because astrocytoma, IDH-mutant, WHO grade 4 is listed on a different row than glioblastoma? It is unclear whether histology 9445 should be classified as being on a different row because it is also listed as a subtype/variant for glioblastoma in Table 3. Table 3 lists histology 9445 as both “Astrocytoma, IDH-mutant, WHO grade 4” and as “Glioblastoma IDH-mutant.” |
Abstract two primaries using the 2024 Malignant Central Nervous System (CNS) and Peripheral Nerves Solid Tumor Rules, Rule M13. Glioblastoma, IDH-wild-type (9440/3) and astrocytoma, IDH-mutant, grade 4 (9445/3) are on two separate rows in Table 3 of the Malignant CNS and Peripheral Nerves Solid Tumor Rules. WHO Classification of Central Nervous System, 5th edition, lists the subtypes of glioblastoma, IDH-wild-type as giant cell glioblastoma; gliosarcoma; and epithelioid glioblastoma. The term glioblastoma multiforme is not recommended for glioblastoma, IDH-wildtype in the 5th edition, and lists astrocytoma, IDH-mutant, grade 4 as a subtype of astrocytoma, IDH-mutant. |

20240042 | EOD 2018/EOD Primary Tumor--Cervix: How is Extent of Disease (EOD) Primary Tumor of the cervix coded when it invades into the bladder on surgery and noted as T4. No further information is provided, and it is not possible to contact the physician for clarification. Would you code 550 (Bladder wall; bladder, NOS excluding mucosa), 750 (Bladder mucosa), or 999 Unknown? |
Assign code 550 (Bladder, NOS excluding mucosa) to EOD Primary Site based on invasion into the bladder with no mention of mucosa. EOD Primary Tumor for cervix, Note 1, instructions are to use the extension information to code primary tumor in preference to a statement of FIGO stage when both are available. TNM staging is closely related to FIGO stage, and the surgical findings of bladder invasion NOS in this case should be used in preference to the statement of T4. |

20240064 | Primary Site/Histology--Ovary: We are encountering a primary site, histologic type, and behavior combination edit based on the Cancer PathCHART (CPC) tables. Using the CPC*Search tool, C569 and 8441/3 is a valid combination. The diagnosis date is 01/13/2024. Should an over-ride be applied with this combination? |
The CPC Validity Status of the site morphology combinations of C569/8441/3 and C569/8441/2 was revised from Valid to Unlikely with the latest release of the Version v24A Edits Metafile. As a result, this site and morphology combination will now require an over-ride flag to be set. Code as 8461/3 (high-grade serous carcinoma) or 8460/3 (low-grade serous carcinoma) if at all possible. Use 8441/3 (serous carcinoma, NOS) only if it cannot be distinguished as low grade or high grade. The codes for high-grade serous carcinoma and low-grade serous carcinoma are relatively new. High-grade serous carcinoma and low-grade serous carcinoma are very different tumors and pathologists should state whether it is high grade or low grade. Please make every attempt to use the newer codes. If unable to determine high gade versus low grade, assign 8441/3 and override the edit. The files on the CPC website are currently being updated, and CPC*Search will be updated to reflect the changes sometime this Fall. |

20240045 | Reportability/Ambiguous Terminology--Prostate: Should cases be reported and abstracted based on ambiguous terminology, e.g., suspicious for prostate cancer, when the physician is not treating the case as malignant? See Discussion. |
Please comment on these specific scenarios.
|
For each of your scenarios, the medical record information indicates that the case is not reportable based on physician opinion. Do not abstract these cases. Remember that the ambiguous terms list is to be used as a last resort. The ideal way to approach abstracting situations when the medical record is not clear is to follow up with the physician. If the physician is not available, the medical record, and any other pertinent reports (e.g., pathology, etc.) should be read closely for the required information. See page 19 in the SEER Manual, https://seer.cancer.gov/manuals/2024/SPCSM_2024_MainDoc.pdf |

20240021 | Solid Tumor Rules/Reportability/Histology--Digestive Sites: Is a diagnosis of “high grade dysplasia” (not specified to be squamous or glandular) reportable for esophagus, stomach, and small intestine for cases diagnosed beginning in 2024? If so, how should histology be coded? See Discussion. |
SEER Program Coding and Staging Manual indicates high grade dysplasia of esophagus, stomach, and small intestine are reportable. The ICD-O-3.2 does not include “high grade dysplasia” as equivalent to “high grade squamous dysplasia.” If reportable, would high grade dysplasia (NOS) that originates in the stomach and small intestine default to 8148/2, while esophageal high grade dysplasia (NOS) default to 8077/2? |
Report these high grade dysplasia of the following organs as stated below. Stomach: Assign code 8148/2 glandular intraepithelial neoplasia, high grade using the Other Sites Solid Tumor Rules, Table 6: Stomach Histologies and as described in the WHO Classification of Digestive Tumors, 5th edition. Small intestine and Esophagus: Assign code 8148/2 glandular intraepithelial neoplasia, high grade, using the Other Sites Solid Tumor Rules, Other Sites Histology Rules, Rule H4/H26. The following note is listed for both of these rules. Note: This list may not include all reportable neoplasms for 8148/2. See SEER Program Coding and Staging Manual or STORE manual for reportable neoplasms The Other Sites Solid Tumor Rules, Table 5: Esophagus Histologies and Table 7: Small Intestine and Ampulla of Vater Histologies will be updated to reflect this code as time permits. |

20240024 | Reportability/Histology: Is angiomyxoma (this includes borderline or behavior code /1 cases) of the soft tissue reportable? Can you provide us with coding guidelines for angiomyxoma for when its reportable or not reportable? |
Do not report angiomyxoma. ICD-O-3.2 assigns 8841/0 to this benign tumor. This includes superficial and deep (aggressive) angiomyxoma. |

|
20240070 | Reportability/Histology: Does Cancer Pathology Coding Histology And Registration Terminology (Cancer PathCHART) determine if the histology is reportable or do we have to use the Excel ICD-O-3.2 spreadsheet? |
The CPC ICD-O-3 Site Morphology Validation Lists (SMVLs) designate all tumor site-morphology combinations that are either valid or impossible as determined for the sites reviewed by the Cancer PathCHART initiative. These lists provide information on the Validity Status of specific tumor site and morphology combinations, similar to the way the ICD-O-3 SEER Site/Histology Validation List used to. However, the CPC SMVLs do not include information on the reportability of specific tumor site and morphology combinations. For tumor reportability, you will continue to use the Excel ICD-O-3.2 spreadsheets posted to the NAACCR ICD-O-3 Coding Updates website: https://www.naaccr.org/icdo3/, and the most recent SEER Manual and federal, state, local, and other standard setters' reportability requirements. |

20240035 | Solid Tumor Rules--Urinary: The example used in Rule M15 of the Urinary Solid Tumor Rules refers to the same row in Table 3. Should the example say Table 2 since Table 3 is non-reportable urinary tumors. See Discussion. |
Rule M15 Abstract a single primary when synchronous, separate/non-contiguous tumors are on the same row in Table 2 in the Equivalent Terms and Definitions. Note: The same row means the tumors are • The same histology (same four-digit ICD-O code) OR • One is the preferred term (column 1) and the other is a synonym for the preferred term (column 2) OR • A NOS (column 1/column 2) and the other is a subtype/variant of that NOS (column 3) OR • A NOS histology in column 3 with an indented subtype/variant Example: TURBT shows invasive papillary urothelial carcinoma 8130/3 and CIS/in situ urothelial carcinoma 8120/2. Abstract a single primary. Papillary urothelial carcinoma and urothelial carcinoma are on the same row in Table 3. |
The example used in Rule M15 of the Urinary Solid Tumor Rules should refer to Table 2. We will update this in the next revision of the Rules. |

20240019 | Solid Tumor Rules/Histology--Head and Neck, Other Sites: Do human papilloma virus (HPV) histologies that occur with subtype/variants of squamous cell carcinoma (SCC) in various sites apply only to sites in Solid Tumor Rules, Head and Neck, Table 5 and Other Sites, Table 23? See Discussion. |
The 2024 Solid Tumor Rules, Table 5: Tumors of the Oropharynx, Base of Tongue, Tonsils, Adenoids contain notes that say beginning 1/1/2022, keratinizing or non-keratinizing SCCs, HPV positive or HPV negative, are coded 8085 or 8086, respectively, for sites listed in the Head and Neck Solid Tumor Rules, Table 5 only. Table 5 introductory section also states for cases diagnosed 1/1/2023 forward: “When the diagnosis is a subtype/variant of squamous cell carcinoma and HPV status is also noted, code the subtype/variant.” This latter instruction is also included in Other Sites Table 23 (Penis and Scrotum Histologies) as a “Penis Coding Note.” Do these instructions ONLY apply to sites on those tables (and only to Penis or to Scrotum also in Table 23)? How should we code HPV-related keratinizing/non-keratinizing or other subtype/variant SCCs, for sites NOT on those tables, given the fact that only the more common histologies are listed in the Solid Tumor tables? For example, we recently reviewed a case with HPV-positive basaloid squamous cell carcinoma of the anus (C21.0). |
Code the specific histology as stated by the pathologist according to the site-specific instructions in the Solid Tumor Rules. When the histology provides a subtype/variant in addition to the HPV histology codes, code the subtype/variant as it is important to capture this histology as in the example provided. the instruction to code the subtype/variant over 8085 or 8086 applies to the following sites: oropharynx, cervix, vagina, vulva, anus, and penis. A note will be added indicatng this in 2025. Per 2024 Cancer PathCHART expert pathologist review, morphology codes 8085/3 and/or 8086/3 are valid and applicable to head and neck, oropharynx, cervix, vagina, vulva, fallopian tube, anus, and penis (reference: Cancer PathCHART: Product Downloads and Timelines). Other coding resources will be updated to reflect these changes in 2025. |

20240063 | Solid Tumor Rules/Multiple Primaries--Bladder: How many primaries and what M Rule applies for a diagnosis of noninvasive micropapillary urothelial carcinoma (8131/2) in 2019, followed by a diagnosis of noninvasive papillary urothelial carcinoma (8130/2) in 2024? |
Abstract two primaries using Urinary Solid Tumor Rules, Rule M12. The histologies include non-invasive papillary urothelial carcinoma (8130/2) and non-invasive micropapillary urothelial carcinoma (8131/3). The two histology codes are listed as subtypes of Papillary urothelial (transitional cell) carcinoma in column 3 of Table 2. WHO Classification of Urinary and Male Genital Tumors, 5th edition classifies micropapillary urothelial carcinoma as an aggressive subtype of urothelial carcinoma with carcinoma in situ present in more than half of all micropapillary carcinomas. Rule 7 Note 3 of the Urinary Solid Tumor Rules states that there are no /2 subtypes for urothelial carcinoma with the exception of papillary urothelial carcinoma and applies to multiple occurrences of /2 urothelial carcinoma of the bladder. Rule 8 applies to 8131/3 and 8120/3. |
