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 |

20240010 | Solid Tumor Rules/Histology--Prostate: Other Sites Solid Tumor RulesTable 3 (Prostate Histologies), Note 1 in the Adenocarcinoma with neuroendocrine differentiation (8574/3) row, conflicts with Note 2 and requires further clarification. See Discussion. |
Note 1 states that this histology is treatment-related neuroendocrine prostatic carcinoma demonstrating complete neuroendocrine differentiation or partial neuroendocrine differentiation with adenocarcinoma after androgen-deprivation therapy (ADT). Conversely, Note 2 says to code 8574/3 only when there is no history of previous prostate adenocarcinoma or history of androgen-deprivation therapy. The WHO Blue Book does confirm this is a treatment-related histology, so it seems we would only use this for an adenocarcinoma with neuroendocrine differentiation (or even possibly a mixed histology tumor with adenocarcinoma and small cell carcinoma components) if the patient had previous treatment. If this histology is treatment-related, why would we use this code for a patient without a history of prostate adenocarcinoma or androgen-deprivation therapy? Should Note 2 be corrected? Does this histology apply to a post-treatment diagnosis of mixed adenocarcinoma and small cell carcinoma? If yes, should this clarification be added? |
Assign code 8574/3 only when there is A history of androgen-deprivation therapy or No history of previous prostate adenocarcinoma Prostate cancer with neuroendocrine differentiation (PCND) can present as untreated primary pathology (i.e., a new primary) or more commonly as a post ADT and androgen receptor inhibition resistance phenomenon. PCND is either a newly diagnosed prostate cancer or a result of ADT indicated for treatment of other prostate cancers or other non-cancer diagnoses (e.g., benign prostatic hyperplasia) but not for the PCND diagnosis. We will edit the notes to make them more clear. |

20240041 | Reportability--Brain and CNS: Is an optic nerve meningioma reportable if stated to arise in the “intraorbital segment” of the optic nerve meninges? See Discussion. |
Patient was diagnosed on imaging with enhancement along the right optic nerve intraorbital segment, displacing the optic nerve, most consistent with optic nerve sheath meningioma. Extracranial meningiomas are rare, however SINQ 20230052 does contain an exception for reportability in a different head and neck site because it is not an intracranial location. It is unclear if this portion of the meninges surrounding the intraorbital optic nerve is still “intracranial” and thus reportable. |
Report optic nerve sheath meningioma arising in the intraorbital segment. The optic nerve contains four segments, of which intraorbital is one. The WHO Classification of Eye Tumors, 4th edition, defines meningioma as a neoplasm originating from the meningothelial cells of the optic nerve leptomeninges. According to the Table 3 of the Non-malignant Solid Tumor Rules, all portions of the optic are reportable and meningiomas arising in the dura/meninges of an intracranial nerve are coded to cerebral meninges C700. |

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. |

20240003 | Solid Tumor Rules/Histology--Head & Neck: How is histology coded for laryngeal intraepithelial neoplasia II-III (LIN II or LIN III)? See Discussion. |
Laryngeal intraepithelial neoplasia II-III is not included in the ICD-O-3.2 and, while the SEER Program Coding and Staging Manual (SPCSM) confirms this is reportable, neither the SPCSM nor the Solid Tumor Rules Manual provide the specific histology to use for LIN II or LIN III. Should this be coded as 8077/2 since this is most like a high grade squamous dysplasia? |
Assign histology code, 8077/2 (squamous intraepithelial neoplasia, high grade) for LIN III and for LIN II. ICD-O-3.2 lists squamous intraepithelial neoplasia, grade II and grade III as 8077/2 indicating it is reportable. ICD-O-3.2 does not list every site-specific type of intraepithelial neoplasia. Check the SEER manual for reportable and non-reportable examples. |

20240049 | First Course Treatment/Neoadjuvant Therapy--Breast: When are pre-operative therapies given as part of a clinical trial coded as neoadjuvant treatment versus limited systemic exposure in the Neoadjuvant Therapy data item? See Discussion. |
The SEER Manual seems to give somewhat conflicting instructions for clinical trial therapies under the Neoadjuvant Therapy data item. One section states that limited systemic therapy may occur in clinical trials to impact the biology of a cancer, but is not a full course of neoadjuvant therapy with the intent to impact extent of surgical resection or other outcomes (organ preservation, function or quality of life); do not code as neoadjuvant therapy for the purposes of this data item. Then another section states for purposes of this data item, the criteria for neoadjuvant therapy include that treatment must follow recommended guidelines for the type and duration of treatment for that particular cancer site and/or histology, and that neoadjuvant therapy may be given as part of a clinical trial. For example, a patient was diagnosed with invasive ductal carcinoma of the breast, 6 cm in size; treatment planning conference recommended neoadjuvant chemotherapy. The patient elected to participate in a clinical trial and was assigned to a group given the antibody drug conjugate datopotamab deruxtecan (Dato-DXd) plus durvalumab for 12 weeks. There was no physician documentation of intent or expected outcomes, nor yC staging or statement of clinical response. Post-therapy imaging showed no residual mass, and post-therapy mastectomy path report showed only residual ductal carcinoma in situ, stating "Treatment Effect (after neoadjuvant): Residual Cancer Burden - pCR, In the breast - complete response." The medical oncologist stated post-therapy stage was ypTis ypN0 cM0. The trial drugs this patient were given do not appear to be approved or standard neoadjuvant/pre-operative drugs in SEER*Rx or NCCN guidelines for this type of cancer; however, the duration of treatment was fairly substantial, and although we don't have clear documentation from physicians as recommended in the SEER manual (which is usually not stated, in our experience), it seems like they may be considering it as neoadjuvant therapy. How should the Neoadjuvant Therapy data item be coded for cases like this? What is the best way to differentiate between clinical trial therapies that are "limited systemic exposure" (code 3) versus true neoadjuvant therapy (code 1)? |
When pre-operative therapies are given as part of a clinical trial, code as neoadjuvant treatment in the Neoadjuvant Therapy data item when the intent is neoadjuvant and/or when surgical resection follows the clinical trial therapies. In the example, neoadjuvant chemotherapy was recommended in the treatment planning and the patient had the planned resection after neoadjuvant treatment. The treatment effect outcome is based on imaging that reported no mass and as documented by the physician, pathologist in this case as complete response to the neoadjuvant therapy based on the resection. Use code 3 (limited systemic exposure) when treatment does not meet the definition of neoadjuvant therapy in the data item, Neoadjuvant Therapy. Limited exposure occurs when the patient receives some therapy prior to surgical resection, but the treatment is not enough to qualify for a full course of neoadjuvant therapy with the intent to impact extent of surgical resection or other outcomes. While this type of treatment may given as part of a clinical trial, it mostly refers to short term treatments such as hormone therapy. When neoadjuvant therapy is given prior to surgical resection that is planned (intended) or performed to improve outcomes, use Code 1 or 2. Because a clinical trial is a type of research study that tests new methods of screening, prevention, diagnosis, or treatment of a disease, the treatment regimens likely will not be incorporated in recommended guidelines until all phases of the trial are completed and approved by the U.S. Food and Drug Administration. ClinicalTrials.gov is available to learn more about clinical studies around the world. |

20240032 | Update to Current Manual/Reportability--Biliary Tract: Is a diagnosis of high grade dysplasia of the gallbladder reportable? See Discussion. |
Patient was diagnosed March 2024 with high grade dysplasia of the gallbladder during excision for clinical history of acute cholecystitis and obstruction. Per the STR, Table 10 for Gallbladder and Extrahepatic Bile Duct Histologies shows Biliary intraepithelial neoplasia, high grade as code 8148/2. High grade glandular intraepithelial neoplasia of the biliary tract is also code 8148/2. Recent SINQ 20240021 (GI specific) indicates high grade dysplasia is reportable as high grade glandular intraepithelial neoplasia (8148/2) for stomach, small intestine, and esophagus. Does the same hold true for gallbladder? If so, then it appears there is a conflict between STR and Appendix E2. However, using the logic of SINQ 20240021 for this site would appear to contradict Appendix E2 which indicates high grade dysplasia in sites other than stomach, intestine, and esophageal sites is not reportable. If we can code high grade dysplasia of GI sites to 8148/2, should we accession high grade dysplasia of the gallbladder and other biliary sites in a similar manner? If so, then Appendix E needs to be modified. |
Report biliary intraepithelial neoplasia (dysplasia), high grade. As noted in SINQ 20240021 and the Other Sites Solid Tumor Rules, Rules H4/H26, the listed sites may not include all reportable neoplasms for 8148/2. We will update the Other Sites Solid Tumor Rules to reflect this code as well as make revisions in the next release of the SEER Manual. |

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. |

20240038 | Solid Tumor Rules/Multiple Primaries--Brain and CNS: How many primaries are accessioned, and what M Rule applies to a 2023 diagnosis of pituitary macroadenoma followed by a 2024 diagnosis of pituitary neuroendocrine tumor (PitNET) when the patient did not undergo surgery, but did undergo hormone therapy with Cabergoline? See Discussion. |
Malignant Central Nervous System (CNS) Rule M5 instructs us to abstract a single primary (as malignant) when a single tumor is originally diagnosed as non-malignant, the “First course treatment was active surveillance (no tumor resection),” and the subsequent resection pathology is malignant. This patient’s first course of treatment was not active surveillance. While the patient did not have first course tumor resection, the tumor was treated with Cabergoline. Should Rule M5 apply because there was no tumor resection? If so, should Rule M5 clearly state no tumor resection is the criteria (not active surveillance)? SINQ 20230023 does indicate a PitNET diagnosis following a diagnosis of pituitary adenoma does not fall into standard rules, but in the previous SINQ the first course treatment was a partial resection. It is unclear whether other types of treatment could result in a new malignant PitNET, following a previously treated non-malignant pituitary tumor. |
Abstract a single primary as 8272/3 (pituitary adenoma/PitNET) using the Malignant CNS and Peripheral Nerves Solid Tumor Rules, Rule M2, a single tumor is always a single tumor. Change the histology of the 2023 diagnosis to 8272/3. This scenario does not meet the criteria in the current rules for M5 in that it requires a resection as part of the criteria. Since the patient did not undergo resection for either diagnosis, the 2024 diagnosis may indicate recurrence or progression. A diagnosis of pituitary adenoma only is still coded 8272/0 (this code is still valid). A diagnosis of pituitary adenoma/PitNET, PitNET, or pituitary neuroendorine tumor is coded 8272/3. Cabergoline is used to treat prolactinoma or high levels of prolactin but does not impact the PitNET. |

20240043 | Reportability/Histology--Digestive Sites: Is a diagnosis of “tubulovillous adenoma with high grade dysplasia” in the duodenum equivalent to a diagnosis of “tubulovillous adenoma, high grade” and, therefore, non-reportable, or is this a reportable non-colorectal high grade dysplasia? See Discussion. |
The 2022 ICD-O-3.2 Implementation Guidelines indicate “Tubulovillous adenoma, high grade” is 8263/2 and is not SEER reportable. However, the 2024 SEER Manual and clarification from recent SINQs (20240021 and 20240025) confirm high grade dysplasia in the esophagus, stomach, and small intestine is reportable (8148/2). Which reportability reference applies to a diagnosis of a tubulovillous adenoma with high grade dysplasia in non-colorectal sites? |
A diagnosis of “tubulovillous adenoma with high grade dysplasia” in the duodenum is not equivalent to a diagnosis of “tubulovillous adenoma, high grade.” Tubulovillous adenoma, high grade (8263/2) is not reportable as of 2022. High grade dysplasia (glandular intraepithelial neoplasia, grade III) is reportable in the esophagus, stomach, and small intestine (8148/2). |
