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. |

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. |

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. |

20240040 | First course treatment--Kidney: How should the different treatment fields be coded if surgery is planned but cancelled due to patient noncompliance, then the tumor is treated with ablation, and eventually surgery is given due to residual disease? See Discussion. |
Patient was diagnosed in July 2022 with biopsy confirmed left kidney renal cell carcinoma. Initially, partial nephrectomy was planned for February 2023 but canceled at the last moment due to the patient’s “history of narcotic use.” The details of that cancellation were otherwise unclear. It appears the treatment plan was changed due to patient non-compliance. Patient then had cryoablation of the tumor in May of 2023. Subsequent imaging in October found residual tumor, but no disease progression was noted. Again, additional ablation was offered but patient decided on surgical treatment which did not occur until December 2023. Is the cryoablation second course due to a change of plan if there is no disease progression, recurrence, or treatment failure? If the cryoablation is first course treatment, then would the partial resection also be first course treatment because it was documented as the treatment plan? |
The treatment with cryoablation is second course. Once the initial treatment plan is changed, everything after the change is no longer first course of treatment. If the cryoablation was not mentioned as part of the original treatment plan, it is second course. |

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. |

20240013 | Solid Tumor Rules/Histology--Testis: Can a definition for "teratoma with somatic-type malignancy" (9084) be added to the Other Sites Solid Tumor Rules? See Discussion. |
We included this histology in SEER Workshop Case 12 and the histology coding accuracy was less than 40%. From emails we received, it is clear that registrars are unaware that the "somatic type malignancy" can vary but code 9084 applies when the diagnosis is teratoma WITH any non-germ cell tumor component. It may be helpful to add a definition for "teratoma with somatic-type malignancy" (9084) to the Solid Tumor Manual. |
We will add the same definition for teratoma with malignant transformation found in the ovary table: 9084/3 Teratoma with malignant transformation when a malignant (/3) histology arises in a benign teratoma. Teratoma with malignant transformation and teratoma with somatic-type malignancy are synonoyms. The term teratoma with somatic-type malignancy is outdated and no longer recommended. |

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. |
