20200060 | First Course Treatment/Reportability: Are there situations for which a case with a class-of-case code in the 30's should be reported to the central registry? We know these are not reportable to the CoC, but should they be reported to the central registry? See Discussion. |
Example: 3/22/2017-26 year old white female seen in the emergency room with abdominal pain. Patient was diagnosed about a month ago with breast cancer. Impression: menstrual pain. In this example the patient is newly diagnosed with breast cancer, but the second hospital does not treat or diagnose the patient; pain management for a separate condition is received only. Is this patient reported due to the history of active disease? |
Work with your central registry to determine which cases they require you to report. In general, any case still undergoing first course of treatment, even if not given at your facility, should be reported to the central registry. Many central registries will appreciate knowing that the patient was seen at your facility to update date last seen and other data items. |

20200045 | Diagnostic confirmation--Heme & Lymphoid Neoplasms: Is Diagnostic Confirmation coded to 5 or 8 based on a patient diagnosed as multiple myeloma by a physician based on a bone marrow biopsy stating plasma cell neoplasm? See Discussion. |
Bone marrow, right iliac crest (aspirate smear, touch preparation, clot section and core biopsy): Hypercellular marrow (40-50%) with plasma cell neoplasm (see Comment): " No evidence of metastatic carcinoma. " Adequate iron storage. Comment: CBC data shows normocytic anemia. Flow cytometric analysis of bone marrow detects a kappa restricted plasma cell population that expresses CD138 and CD38. CD56 is positive. CD19 and CD20 are negative. T lymphocytes are immunophenotypically unremarkable. Polyclonal B lymphocytes are detected. Blast gate is not significantly increased. Immunohistochemical stains are performed on the biopsy core and clot section for greater sensitivity and further architectural assessment with adequate controls. CD138 positive plasma cells comprise > 70% of the total cellularity. AE1/AE3 is negative. Taken together, the morphologic and immunophenotypic findings are consistent with a diagnosis of plasma cell neoplasm. Trilineage hematopoietic activity as are seen. |
This would be a Diagnostic Confirmation of 8 based on the physician's diagnosis. The Pathology report mentions plasma cell neoplasm only. By itself, plasma cell neoplasm is not reportable because it includes a variety of diseases, some that are not reportable, and some that are (See Hematopoietic Database under Plasma Cell Neoplasm.) The physician probably has other information, including imaging, which may show lytic lesions. He/she is probably using clinical findings, plus findings from the bone marrow, and diagnosing this patient with multiple myeloma. |

20200088 | Histology--Heme & Lymphoid Neoplasms: Is there an inconsistency between the histologies listed as deleted in the ICD-O-3.2 Implementation Guidelines and the obsolete histologies in the Hematopoietic and Lymphoid Neoplasms Database (Heme DB)? See Discussion. |
While we recognize the Heme DB has been the correct source for histology coding for heme and lymphoid neoplasms dating back to 2010, the ICD-O-3.2 Implementation Guidelines appear to provide incorrect coding instructions. Histologies 9670/3, 9728/3, 9729/3 and 9836/3 are listed in Table 3 - Deleted ICD-O codes in ICD-O-3.2. While we recognize these histologies have been included in this Table because they have now been deleted, it is unclear whether the Comments regarding their use listed in the 4th column of the Table is correct. For each of these histologies, the comment states the histology listed in the 1st column (ICD-O-3/3.1) should be used prior to 2021. For example, for histology 9670/3, the comment states: Cases diagnosed prior to 1/1/2021 use code 9670/3. Cases diagnosed 1/1/2021 forward use code 9823/3. However, each of these histology codes have been obsolete for cases diagnosed 1/1/2010 and later. If registrars were following the Heme DB and Heme Manual instructions (the appropriate coding source for these neoplasms), these histologies would not have been used in a decade. Should the Comments column in Table 3 be updated? Or should a Note follow the Table indicating registrars should not use these histology codes for cases diagnosed after 1/1/2010, and these histology codes have been deleted for cases diagnosed 1/1/2021? It seems misleading to indicate any of these are valid histology codes for a 2010-2020 diagnosis when the Heme DB confirms these histology codes only apply to cases diagnosed prior to 2010. |
Follow the Heme DB to determine which codes are obsolete as of 2010. These histologies were made obsolete based on the 2010 WHO Hematopoietic book and confirmation with physicians. The official changes from ICD-O-3 were not implemented until ICD-O-3.2 Also, edits will not allow these histologies to be used for cases diagnosed 2010 and later. The ICD-O tables were based on documentation from IARC ICD-O committee and may differ from practices in North America. |

20200078 | Solid Tumor Rules (2018)/Histology--Brain and CNS: Should the new malignant term pituitary blastoma be added to Table 3 of the 2018 Malignant Central Nervous System (CNS) and Peripheral Nerves Solid Tumor Rules? See Discussion. |
Pituitary blastoma was not added to Table 3 (Specific Histologies, NOS, and Subtypes/Variants) of the 2018 Malignant CNS and Peripheral Nerves Solid Tumor Rules as part of the December 2020 update. This is a new malignant CNS histology for 2021 and later. Not including this histology in Table 3 results in the registrars being required to check another source to correctly code this histology. If this histology cannot be used for cases diagnosed prior to 2021, should that diagnosis year clarification be included in the STR? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
The Solid Tumor Malignant CNS tables do not list pituitary specific histologies at this time. Registrars will need to refer to ICD-O and/or updates until the decision to add malignant pituitary neoplasms is made. Pituitary blastoma is a rare tumor which occurs in children. |

20200077 | Solid Tumor Rules (2018)/Histology--Kidney: What is the histology code for succinate dehydrogenase-deficient renal cell carcinoma (SDHD)? See Discussion. |
Table 1 of the 2018 Kidney Solid Tumor Rules (STR) lists succinate dehydrogenase-deficient renal cell carcinoma as histology code 8312, but in the ICD-O-3.2 Coding Table it is listed as histology code 8311. No changes were made in the Kidney STR. As a result, the histology change described in the ICD-O-3.2 Coding Table conflicts with Table 1. Succinate dehydrogenase-deficient renal cell carcinoma (SDHD) is listed in Table 1 as a synonym for renal cell carcinoma, NOS (8312). However, the ICD-O-3.2 Coding Table lists this as a related term for histology code 8311/3. This related term was not discussed in the Implementation Guidelines, and no change was noted in the STR. While it seems we should continue to follow the STR, without clarification as to why this histology change was not implemented in STR, achieving consistency will be problematic if registrars jump straight to the ICD-O-3.2 Coding Table to code histology for cases diagnosed 2021 and later. If this code cannot be used for cases diagnosed prior to 2021, should that clarification be included in the STR? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
When creating table 1, our GU SME's stated Succinate dehydrogenase-deficient renal cell carcinoma (SDHD) is a rare neoplasm and is coded to RCC, NOS until such time a new code is proposed in the 5th Ed BB. ICD-O-3.2 added this term to 8311 as a related term BUT there is no documentation that these neoplasms are different and should be on separate lines in table 1 making them separate primaries. Its likely IARC made the decision to group these rare genetic histologies into one code. SEER is waiting for confirmation from GU experts. If it's valid, the RCC row will be updated in columns 2 and 3 with applicable dates each histology is valid. |

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. |

20200013 | Solid Tumor Rules (2018)/Multiple primaries--Colon: Solid Tumor Rules 2018, Colon Rule M7, bullet 3 indicates that (if neither bullet 1 or 2 apply) a new tumor at the anastomotic site must be stated to arise in the mucosa (confirmed in SINQ 20190096) to qualify as a new primary. However, there is often no clear statement of tumor arising from or involving mucosa (unless the new tumor is limited to the mucosa) noted by pathologists in our region. Do any of the following examples imply a new tumor arising in mucosa per Rule M7, bullet 3? See Discussion. |
Examples: 1) New tumor at the ileocolic anastomosis, described as a, Circumferential centrally ulcerated mass with raised borders. Tumor extension: Tumor invades through muscularis propria into subserosal adipose tissue, no involvement of the serosal surface identified. The only mention of mucosa on the resection is the uninvolved enteric mucosa or uninvolved colonic mucosa in the otherwise uninvolved portions of the ileum/colon. If neither bullet 1 or 2 apply, is this a new primary per M7 bullet 3? 2) Right colon with anastomosis site. Tumor site: Anastomosis. Tumor extension: Tumor invades through the muscularis propria. Gross description does not describe mucosa, only noting, at the central area of anastomosis is an ill-defined, slightly raised, tan-brown to purple mass measuring 2.2 x 2 cm, which is nearly circumferential, causing obstruction at the site of anastomosis. If neither bullet 1 or 2 apply, is this a new primary per M7 bullet 3? 3) Polyp at ileocolonic anastomosis, polyp biopsy final diagnosis was, Invasive moderately differentiated colonic adenocarcinoma in association with adenoma. No mention of mucosa on the biopsy final diagnosis or gross description. Clinical info indicates, There is an ulcerated 5 cm mass at the ileo-colonic anastomosis that was biopsied. If neither bullet 1 or 2 apply, is this a new primary per M7 bullet 3? |
Following the 2018 Colon Solid Tumor Rules M7 and M8: Example 1: Assuming the first and second tumors are not different histologies or they occurred less than or equal to 24 months apart (M7 Bullets 1 and 2 do not apply), abstract a single primary as the pathology states uninvolved enteric mucosa or uninvolved colonic mucosa (no involvement noted). Example 2: Assuming the first and second tumors are not different histologies or they occurred less than or equal to 24 months apart (M7 bullets 1 and 2 do not apply), abstract a single primary as there is no mention of mucosal involvement. Example 3: Assuming the first and second polyps/tumors are not different histologies or they occurred less than or equal to 24 months apart (M7 bullets 1 and 2 do not apply), abstract a single primary as there is no mention of mucosal involvement. Of note in the case of the polyp, tumors coded as adenocarcinoma in a polyp, should be treated as adenocarcinoma (8140) for cases prior to 2018. Also, if the pathologist states the new tumor/polyp originated in the mucosa, it is a new primary. The rules which address "recurrence or new tumor at the anastomosis were created with the input of several gastrointestinal expert pathologists (CAP, AJCC, and WHO). Pathologists should be following CAP reporting guidelines and include information such as mucosal involvement in the final diagnosis and/or synoptic report. We can revisit this question that all polyps start in the mucosa and if needed, revise the rules to state this. |

20200027 | Reportability--Ambiguous Terminology: Should either of the terms, strongly characteristic of or most certainly, be used to accession a case as reportable when they are used to describe a malignancy and no other information is available? See Discussion. |
SINQ 20130140 indicates a histologic diagnosis that is characteristic of a specified malignancy is reportable because this is equivalent to the term, diagnostic of. Does the same logic apply to a clinical diagnosis that is strongly characteristic of a malignancy on imaging? SINQ 20180104 indicates the term, almost certainly, is not a reportable ambiguous term. If a radiologist notes a mass was most certainly malignant, is this adequate to accession this as reportable? Is a clinically certain diagnosis equivalent to diagnostic of? Or are the modifiers almost and most irrelevant because the terms certainly and certain are not on the ambiguous terminology list? |
Look for more information. What is the plan for each of these patients? Consult with the physician and search for further information to assist with the decision. If no further information can be obtained, accession both of these cases based on the imaging reports. If more information becomes available later, review and revise as applicable. |

20200079 | Solid Tumor Rules (2018)/Primary Site--Brain and CNS: Should the updated note for optic nerve glioma be included in both the 2018 Solid Tumor Rules for Malignant Central Nervous System (CNS) and Peripheral Nerves, Note 6, and the Non-Malignant CNS Tumors, Note 5? See Discussion. |
Should the updated Note 5 from the Non-malignant CNS regarding optic nerve glioma also be incorporated into Note 6 for Malignant CNS rules (the pilocytic astrocytoma note)? This was one of the major issues identified in the SEER*Educate Workshop. Registrars have demonstrated they do not consistently think to look at the Non-malignant CNS schema when they see the term glioma and continue to misclassify optic nerve gliomas as malignant. This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
The 2022 Solid Tumor Update will include a new note in the Terms & Definitions, Introduction section that will state: See the Non-malignant CNS rules when the primary site is optic nerve and the diagnosis is either optic glioma or pilocytic astrocytoma. The behavior is non-malignant and coded 9421/1. |

20200062 | Solid Tumor Rules (2018)/Multiple Primaries--Lung: How many primaries should be reported when a patient has a 7/2016 diagnosis of right lower lobe lung mucinous adenocarcinoma, treated with Erlotinib and Avastin? In 4/2020, a liver biopsy finds metastatic high grade neuroendocrine carcinoma, clinically stated to be metastatic lung cancer, with no evidence of a new primary lung tumor on PET (liver the only site of disease)? See Discussion. |
We think this should be a single primary because the Solid Tumor rules do not apply to metastases. However, we are not sure whether or not the instructions outlined for prostate (SINQ 20180088, 20130221), that indicate we are to accession a new metastatic tumor only with a small cell neuroendocrine histology after an adenocarcinoma, also applies to lung primaries. We are aware of a phenomenon in which lung adenocarcinoma cases treated with Erlotinib can transform to small cell, but do not know whether it impacts the number of reportable primaries. |
Accession two primaries, adenocarcinoma [8140/3] and small cell neuroendocrine carcinoma [8041/3] per Rule M8 of the Lung Solid Tumor Rules, as these histology codes are on different rows in Table 3 of the rules. This is consistent with similar prior SINQ questions. |
