20200032 | Date of Diagnosis--Brain and CNS: How is the Date of Diagnosis coded when an MRI clinically diagnoses a borderline brain tumor on 4/4/2020, but the subsequent biopsy pathologically diagnoses a malignant brain tumor on 5/20/2020? See Discussion. |
Clinically, the patient was felt to have a pineocytoma (borderline tumor) on imaging, but the subsequent biopsy proved a pineal germinoma (malignant tumor). The Date of Diagnosis instructions state to code the month, day and year the tumor was first diagnosed, clinically or microscopically, by a recognized medical practitioner, but it does not indicate whether differences in behavior alter the diagnosis date. For brain and central nervous system tumors, should the diagnosis date be the first date a tumor is SEER reportable? Or should the diagnosis date for those tumors ultimately proven to be malignant, be the date the malignancy was diagnosed? |
This tumor was first diagnosed on 4/4/2020 according to the information provided. The pineocytoma was reportable based on a behavior of /1; it was later confirmed as a pineal germinoma; update both the histology and behavior on the abstract as better information was obtained, retaining the original date of diagnosis. |

20200020 | Reportability/Brain and CNS--Pituitary: Can a clinical diagnosis of pituitary adenoma be accessioned based on imaging if treatment is not given and subsequent imaging years later shows no evidence of pituitary adenoma? See Discussion. |
The patient was clinically diagnosed with a pituitary adenoma on MRI in June 2009. The MRI noted an unusual contour involving the superior margin of the pituitary gland and the clinical interpretation was a small pituitary adenoma. The patient did not follow-up with the recommended repeat imaging and never received treatment for the pituitary adenoma. The patient was eventually seen again in January 2020 and the MRI showed no adenoma in the pituitary gland. Since pituitary adenomas are known to spontaneously regress, should the 2009 diagnosis of pituitary adenoma be accessioned as a SEER reportable benign central nervous system (CNS) tumor? |
Pituitary adenoma is reportable even if it later regresses without treatment. Use text fields to record the details of this case. |

20200083 | Reportability/Histology--Kidney: Is hybrid oncocytic chromophobe tumor reportable for cases diagnosed 2021 and later? If so, how is the histology coded? See Discussion. |
The ICD-O-3.2 Coding Table includes hybrid oncocytic chromophobe tumor as a related term for histology code 8317 (Renal cell carcinoma, chromophobe type). However, this related term is not discussed in the implementation guidelines as being a new term/reportable tumor. The Solid Tumor Rules do not indicate a hybrid oncocytic chromophobe tumor is reportable; however, if a registrar only looked at the ICD-O-3.2 Coding Table, it may seem as though this histology should be collected. The term hybrid oncocytic chromophobe tumor was not included in the Solid Tumor Rules as a subtype/variant of RCC, or as an equivalent term for chromophobe RCC. There is a SINQ (20180047) that states not to report renal hybrid oncocytic tumor, despite the fact these tumors exhibit mixed features of both oncocytoma and chromophobe RCC. For cases diagnosed 2021 and later, should the clarification in the SINQ apply? Or should the ICD-O-3.2 Coding Table be used which indicates this is a reportable diagnosis? If the standard setters decided not to implement use of hybrid oncocytic chromophobe tumor for 2021, can clarification be added to the Solid Tumor Rules or Implementation Guidelines? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
Hybrid oncocytic chromophobe tumor is listed in ICD-O-3.2 as 8317/3 which indicates it is reportable if diagnosed in 2021 or later. For cases diagnosed 1/1/2021 and later, use ICD-O-3.2 for reportability. See page 16 of the NAACCR 2021 Implementation Guidelines. Between publication of ICD-O-3.2 and updates made to solid tumor histology tables, additional terms were added based on review by the IARC ICD-O committee. These changes were not made available in time to correct the tables. All related terms or synonyms may not be included in the histology tables and ICD-O-3.2 should be used in tandem with the solid tumor rules. |

20200059 | Reportability--Kidney: Is Bosniak 4 cystic lesion of right kidney reportable, and would the first CT date be the date of diagnosis? See Discussion. |
CT a/p read by radiologist shows: "Bosniak 4 cystic lesion of right kidney." Follow-up MRI a month later reads "right kidney cystic lesion with enhancing mural nodule concerning for cystic renal cell carcinoma (RCC)." Urologist consult used the same wording of "Bosniak 4 cystic lesion" and "concerning for renal cell carcinoma." Treatment discussed but due to patient health status recommended repeat imaging. Repeat CT few months later reads: "cystic right renal lesion with enhancing nodule similar to most recent prior and suspicious for cystic RCC." Though "suspicious for cystic RCC" per latest imaging is reportable, Bosniak 4 is "clearly malignancy, ~100% malignant" by definition, so is the case actually reportable with the first CT a/p date as date of diagnosis? |
2023 Bosniak 4 is defined as "clearly malignant cystic mass." The case is reportable as of the first date it is diagnosed as a Bosniak 4 lesion unless further workup (especially biopsy or resection) disproves the CT findings. https://radiopaedia.org/articles/bosniak-classification-system-of-renal-cystic-masses?lang=us |

20200006 | Reportability--Retina: Is a diagnosis of retinal astrocytoma reportable? See Discussion. |
There is no specific ICD-O-3 code for a which resulted in abstractors assigning the malignant astrocytoma, NOS code. These lesions were previously called but we are seeing the new terminology more frequently. |
Report retinal astrocytoma. The WHO Classification of Tumors of the Eye, 4th edition, lists astrocytoma, NOS as 9400/3 with astrocytic hamartoma of the retina as a synonym. You may receive a site/type edit (IF25) which can be overridden. The changes in terminology, codes, etc. proposed in WHO 4th Ed Eye book were implemented for cases diagnosed 1/1/2018 forward. Apply this to retina astrocytomas and do not accession cases diagnosed with this histology prior to 1/1/2018. |

20200063 | Solid Tumor Rules (2021)/Laterality--Melanoma: Will the table called Site for Which Laterality Code Must Be Recorded be updated in the 2021 SEER Program Coding and Staging Manual as C444 is not included? The 2021 Cutaneous Melanoma Solid Tumor Rules say that C444 requires laterality; it says (new) beside it on the new Solid Tumor Rules for 2021. |
The laterality table in the 2021 SEER manual will not be updated. Please follow the 2021 Cutaneous Melanoma Solid Tumor Rules and assign a laterality for C444. |

20200086 | Solid Tumor Rules (2018)/Histology--Head & Neck: Paraganglioma, NOS is reportable and malignant for cases diagnosed 1/1/2021 and later. Paraganglioma, NOS is listed in the ICD-O-3.2 Coding Table as 8680/3 without synonyms or related terms. Table 4 (ICD-O-3.2 Implementation Guidelines) lists 8693/3 Paraganglioma as a new preferred term. Is this correct? See Discussion. |
Table 4 (Changes in reportable terminology), 2021 ICD-O-3.2 Update, does confirm that the term malignant no longer needs to be used to describe a paraganglioma, but Table 4 includes the histology for extra-adrenal paraganglioma, NOS (8693/3) as the new preferred term for paraganglioma. Paraganglioma, NOS is histology code 8680/3. Which code is correct? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
The correct code for extra-adrenal paraganglioma is 8693/3. The preferred term for 8380/3 is Paraganglioma, NOS. Table 4 of the 2021 ICD-O update was based on information from WHO. Table 9 in the Head and Neck ST rules is being revised and formatted differently for ease of coding based on diagnosis year (prior to 2021 and 2021 forward). Not ALL paragangliomas will be included in Table 9. If a term and code are not provided in the rules, refer to ICD-O and updates. |

20200028 | 2018 EOD Primary Tumor/2018 EOD Mets--Lung: Is EOD Primary Tumor coded to 500 and EOD Mets 10 when there are bilateral lung nodules with nodules in same lobe as the primary tumor? How is EOD Primary Tumor coded when separate tumor nodes are in an ipsilateral lung but there is no documentation as to whether it is in the same or different ipsilateral lobe from the primary tumor? |
Assign 999 to EOD Primary Tumor if this is the only information you have for your case.The mention of nodules does not automatically mean that you have separate tumor nodules. There are many reasons for the appearance of nodules in the lung, some of which are not due to cancer. Unless you have further information on whether the physician has determined that they are related to the lung cancer, then assume that they are not related. Assign 00 to EOD Mets. Do not code EOD Mets to 10 since you cannot determine whether those nodules are based on the tumor or not. If you are able to obtain more information, then you can update the EOD Primary Tumor and EOD Mets. Regarding the second question, if separate tumor nodules are noted, you cannot assume that they are due to tumor. Further information, or clarification, is needed on whether the separate tumor nodules are related to the lung cancer. Without further information, code EOD Primary Tumor to 999. There is also some information in the CAnswer Forum since Separate Tumor Nodules are a Site-Specific Data Item: http://cancerbulletin.facs.org/forums/forum/site-specific-data-items-grade-2018/96061-lung-separate-tumor-nodules |

20200053 | Solid Tumor Rules (2018)/Multiple primaries--Bladder. Would the metastatic diagnosis indicate a new primary? If the metastatic diagnosis indicates a new primary, would the primary site be C688 and date of diagnosis 11/14/18? See Discussion. |
7/8/16 Urinary bladder, biopsy: Non-invasive low grade papillary urothelial carcinoma. Muscularis propria (detrusor muscle) is not identified. 9/2/16 Urinary bladder, bladder tumor, transurethral resection: High grade papillary urothelial carcinoma. No definite invasion identified. Muscularis propria (detrusor muscle) is identified and not involved by tumor. 1/7/17 A\S\Bladder: Noninvasive low grade papillary urothelial carcinoma. Granulomatous cystitis, consistent with BCG (Bacillus Calmette-Guerin) treatment. Lamina propria is not involved with tumor. Detrusor muscle is not identified. 4/4/17 Dome: Papillary urothelial carcinoma, low grade. No evidence of invasion. Muscularis propria is not present. Patient is clearly followed for at least a year but no further information until 19 months later, 11/14/18, when biopsy of lung indicates metastatic disease. 11/14/18 Lung, right lower lobe, mass, biopsy: Metastatic urothelial carcinoma. Immunohistochemical analysis results (CK7 positive, CK20 focally positive, P63 positive, GATA3 positive, TTF1 negative and NAPSIN-A negative) support the diagnosis |
Do not use the solid tumor rules to assess the 2018 diagnosis. See Note 1 on page 20 of the Urinary Sites Solid Tumor Rules, https://seer.cancer.gov/tools/solidtumor/Urinary_STM.pdf The 2018 diagnosis proves that this patient had invasive bladder cancer. Change the behavior on the abstract to /3 and use text fields to record the details. |

20200022 | Solid Tumor Rules (2018)/Multiple primaries--Breast: How many primaries should be reported for a December 2013 diagnosis of lobular carcinoma in situ (8520/2) in the left breast, treated with a lumpectomy, followed by a July 2018 diagnosis of invasive ductal carcinoma (8500/3) also in the left breast? See Discussion. |
In the April and July 2019 updates to the Solid Tumor Rules, the term simultaneous and Note 1 indicating histologies must be the same behavior were removed from rule M10 (ductal and lobular are a single primary). We would like to confirm that rule M10 is the correct rule to apply to this case. This case is an invasive diagnosis approximately 4.5 years after an in situ diagnosis, so it seems like M17 should apply (invasive tumor following an in situ tumor more than 60 days later are multiple primaries). An invasive tumor following an in situ tumor more than 60 days later of the same histology is a new primary. Similarly, it seems like an invasive tumor following an in situ tumor more than 60 days later of different histologies should be a new primary. |
Abstract a single primary using 2018 Breast Solid Tumor Rule M10. Unless the tumors were diagnosed more than 5 years apart, they are a single primary. The 2021 breast update will include examples and notes plus updating table 2. |
