20220048 | First Course Treatment/Immunotherapy--Other Therapy: Should all therapies given as part of a clinical trial be coded as Other Therapy (NAACCR #1420), or only those that cannot be classified in one of the other treatment categories (systemic therapy, surgery, radiation) or as ancillary treatments? Does it matter what is listed in SEER*Rx under Primary Sites or Remarks regarding FDA approvals? See Discussion. |
The SEER Manual states that the Other Therapy data item identifies treatments given that cannot be classified as surgery, radiation, systemic therapy, or ancillary treatment; and the instructions for code 2, Other-Experimental, say to assign this for any experimental or newly developed treatment, such as a clinical trial, that differs greatly from proven types of cancer therapy. Does this mean that only unclassifiable treatments should be coded in Other Therapy, even if given as part of a clinical trial? For example, if a patient is given a drug as part of a trial that is categorized in SEER*Rx as immunotherapy, should it be assigned both Immunotherapy (NAACCR #1410) code 1 and Other Therapy code 2, or only coded in Immunotherapy since it is classified as such? How should a clinical trial drug be coded if it has a treatment classification in SEER*Rx, but the type of cancer being treated is not listed under the Primary Site or Remarks sections as being FDA approved? A real case scenario is atezolizumab given for colon cancer as part of a trial; this drug's category is Immunotherapy in SEER*Rx but colon is not listed under Primary Sites or in the Remarks detailing FDA approvals. |
When a drug is being administered as part of a clinical trial and it is not yet approved as treatment for the cancer site for which it is being administered, code in Other Therapy. Do not code it as Immunotherapy (for the example provided). While a drug may be approved to treat one type of malignancy, it may be in clinical trials to determine its value in treating other malignancies. Coding as immunotherapy is misinformation in this case since there are other types of approved immunotheraputic agents. |

20210055 | Tumor Size--Pathologic/EOD 2018: How is Tumor Size--Pathologic coded when Extent of Disease (EOD) Primary Tumor is 800 (No evidence of primary tumor) and there has been no surgery to the primary site? See Discussion. |
The SEER Manual states to assign Tumor Size--Pathological code 000 when EOD Primary Tumor is coded to 800 (No evidence of primary tumor) for any schema. However, the definition of Tumor Size--Pathologic states that it records the size of a solid primary tumor that has been resected. If the primary site has not been resected (does not meet the pathologic staging criteria), then it seems that Tumor Size Pathologic should be 999 when EOD Primary Tumor is coded as 800. |
Assign code 999 for Tumor Size--Pathologic when there is no surgery of the primary site. Code 999 includes "No excisional biopsy or tumor resection done." |

20190014 | Reportability--Behavior: Is reportable if it shows invasion or microinvasion pathologically? See Discussion. |
The SEER Manual states, Generally, this rule is invoking the Matrix principle in the ICD-O-3. We are aware this is not the same as a VIN III or an adenoma with microinvasion because those tumors have a valid histology code listed in the ICD-O-3. The terms or or do not have a valid ICD-O-3 code to apply the Matrix principle. If severe dysplasia is felt to be consistent with a carcinoma in situ, then a severe dysplasia with microinvasion would be reportable as 8010/3. But in the U.S., we do not accession severe dysplasia as equivalent to carcinoma in situ unless the pathologist also states the severe dysplasia is equivalent to carcinoma in situ (e.g., ). |
Severe dysplasia alone is not reportable. No further instructions apply because this term is not reportable.In order to use the instructions for behavior, you must first have a reportable neoplasm. If carcinoma in situ is mentioned and there is microinvasion, code the behavior as /3 according to the instructions in the SEER manual. You are correct, do not accession severe dysplasia as equivalent to carcinoma in situ unless the pathologist also states the severe dysplasia is equivalent to carcinoma in situ (e.g., ). |

20140065 | Summary Stage 2000--Melanoma: How should Summary Stage 2000 be coded for 2014+ diagnosed melanoma cases with satellite nodules or in transit metastases? See discussion. |
The SEER SS (SSS) 2000 Manual indicates satellite nodules (NOS or less than/equal to 2cm from primary tumor) are regional by direct extension (code 2) and in-transit metastasis (satellite nodules greater than 2 cm from primary tumor) are coded as involvement of regional lymph nodes (code 3). However, CSv0205 indicates mapping for satellite nodules/in transit metastasis (coded in CS LN) was changed to Regional, NOS (code 5). There are no definitions listed for code 5 in the SSS 2000 Manual.
Our staff independently code SSS 2000. Should we code the existence of satellite nodules and in transit metastases according to the current definitions in the SSS 2000 Manual or using the mapping information from CSv0205? |
Code the existence of satellite nodules and in transit metastases according to the current definitions in the SSS 2000 Manual. Do not use the mapping information from CS to code SSS. |

20160004 | First course treatment/Other therapy: How is Sirolimus (Rapamycin) to be coded when given with known chemotherapy agents in a clinical trial? See discussion. |
The SEER*Rx Database lists Sirolimus as an ancillary agent under the Category section, but as an mTOR inhibitor under the Subcategory. The Remarks section indicates Sirolimus (AKA Rapamycin) is an immunosuppressant, but is also a type of serine/threonine kinase inhibitor. Other types of kinase inhibitors (including Temsirolimus) are types of Chemotherapy. Although the Coding section states this drug should not be coded, Primary Sites (NSCLC and glioblastoma) are listed for this drug. The SEER*Rx Database page for this drug is confusing. Please address the following. 1) Should Sirolimus not be coded when it is being given as a kinase inhibitor or an immunosuppressant? 2) If Sirolimus is ever treatment, should it be coded only for the primary sites listed? 3) If Sirolimus is given as part of a non-blind clinical trial for another site other than NSCLC or glioblastoma, should the Other Therapy field be coded to 2 [experimental - other treatment]? |
Sirolimus is used to treat GVHD (graft versus host disease) and is not coded as treatment. Even though the sub-category is mTOR inhibitor it does not automatically mean it is a chemotherapeutic agent. Sirolimus affects cells differently than Temsirolimus. The chemical compounds differ between these drugs. In order to code rapamycin, the drug given must be stated to be either the analog or ester compound. The SEER*RX database has been corrected and NSCLC/glioblastoma are no longer listed for sirolimus. We researched clinical trials and found several that include sirolimus with other chemotherapy drugs for patients who either have received or will be receiving bone marrow transplants for hematologic diseases. In this case it is not coded. There are a few trials that are looking at sirolimus as a treatment for bladder, prostate, nerve sheath tumors, MDS, and AML. For these cases it would be coded in Other (code 2). |

20150029 | First course treatment/Hormone Therapy--Lung: How is this field coded when the patient receives Prednisone for a metastatic lung adenocarcinoma? See Discussion. |
The SEER*Rx Database, Prednisone Primary Site indicates "Prednisone is used to treat multiple sites and histologies." The Remarks information states, "Prednisone may be coded as treatment (hormonal) for all sites and histologies. It is most often used as part of a drug regimen." While it is clear that Prednisone is coded as hormone therapy when administered as part of a drug regimen like CHOP, how is Prednisone coded when given outside of a drug regimen? Also, how is Prednisone coded for cancer-directed treatment of a metastatic lung primary? The NCI's PDQ does not list hormone therapy as cancer-directed treatment for a Stage IV lung adenocarcinoma.
In our specific case, Prednisone was started just after diagnosis, and before the completion of work-up proving distant metastasis. Often, Prednisone (or another hormone agent) is given as an ancillary treatment for the symptoms associated with the malignancy, and not as cancer-directed treatment.
|
Do not code Prednisone when it is given for symptoms. In most cases when Prednisone is given by iteself, not as part of a drug regimen, it does not affect the cancer and would not be coded as treatment. |

20220044 | Solid Tumor Rules (2018/2021)/Histology--Head & Neck: What is the histology code for a uvula (C052) primary with histology of squamous cell carcinoma, conventional (keratinizing) and p16 result is negative? See Discussion. |
The Schema ID for C051 (soft palate, NOS) and C052 (uvula) is Oropharynx (either 00100 or 00111 depending on p16). The Solid Tumor Rules Manual includes these site codes are under Table 4: Tumors of Oral Cavity and Mobile Tongue site group for histology coding. We are aware of the notes that allow coding of 8086 for keratinizing SCC, HPV-negative for sites listed in Table 5 only. However, it seems like C051 and C052 were incorrectly omitted from Table 5 (mis-categorized under Table 4). Can we code 8085 for 8086 for C051 or C052 based on p16/HPV status? |
Assign code 8071/3 for keratinizing squamous cell carcinoma. Codes 8085 and 8086 are only valid for the Head and Neck sites listed in Table 5 beginning with cases diagnosed 01/01/2022 and forward. |

20051083 | Multiple Primaries--Lymphoma: How many primaries should be reported when there is a marginal zone B-Cell lymphoma [9699/3] diagnosed in 2000, and the clinician states that the diffuse large B-Cell type lymphoma [9680/3] diagnosed in 2004 was a transformation of the prior primary? See Discussion. |
The Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates they are most likely "D" different disease processes. As any low grade lymphoma can transform, we suspect this represents a transformation (the clinician is regarding this as transformed). How many primary/ies should be coded? And, how? |
For cases diagnosed prior to 1/1/2010: Report this case as one primary according to the physician's opinion. Code the histology as 9699/3 [marginal zone B-Cell lymphoma, NOS] and code the date of diagnosis as 2000. Code the physicians opinion regardless of whether or not it agrees with the Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table. Use the table when the physician does not state whether or not there is a new primary. For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20180083 | Solid Tumor Rules (2018)/Multiple primaries--Bladder: How many primaries are abstracted and which M Rule applies when a patient is diagnosed with an invasive urothelial carcinoma tumor of the bladder, followed less than three years later by an invasive urothelial carcinoma and small cell neuroendocrine carcinoma tumor of the bladder? See Discussion. |
The Solid Tumor Rules indicate bladder tumors that are urothelial carcinoma (8120) and small cell carcinoma (8041) are separate primaries per Rule M13 (Abstract multiple primaries when separate/non-contiguous tumors are on different rows in Table 2). These are distinctly different histologies and, presumably, one would want to capture the small cell carcinoma (or small cell carcinoma component) as this has a worse prognosis. However, if a subsequent bladder tumor is composed of invasive urothelial carcinoma and small cell neuroendocrine carcinoma, the histology is coded as 8045/3 per Rule H4, but this is not abstracted as a multiple primary. The only M Rule that applies is Rule M18 (Abstract a single primary when tumors do not meet any of the above criteria). The mixed histology code 8045 is not included in Table 2, so none of the histology-based M Rules apply. Is the subsequent mixed invasive urothelial and small cell carcinoma tumor (8045/3) the same primary as a previously diagnosed invasive urothelial carcinoma (8120/3) when these tumors are diagnosed within three years? |
Abstract two separate primaries using Solid Tumor Rules Urinary Sites Rule M13. While not stated in the urinary sites rules, these are separate histology codes in two different rows in Table 2 of the Rules. The initial histology is 8120 and the subsequent tumor is 8045 using Rule H4. Adding 8045 to Table 2 will cause issues. Small cell neuroendocrine in the bladder is very rare, extremely aggressive, and usually has a component of urothelial carcinoma. |

20230071 | Solid Tumor Rules/Histology--Cervix: How is histology coded for a 2023 endocervical adenocarcinoma negative for high-risk human papilloma virus (HR-HPV) on Pap smear and strongly positive for p16 on biopsy? See Discussion. |
The Solid Tumor Rules indicate p16 is a valid test to determine HPV status and can be used to code HPV-associated/-independent. In this case, we do not know whether the HR-HPV test was done on cytologically malignant cells, or on benign cervical cells. It may be impossible to tell unless 100% of the cytology specimen is malignant, but we will not have access to that information. Also, HR-HPV testing is routine on Pap smears, so this testing does not mean the tumor cells specifically harbor HPV. |
Assign histology as adenocarcinoma, HPV-associated (8483/3) as designated in Table 17, Uterine Cervix Histologies, of the Other Sites Solid Tumor Rules. The WHO Classification of Female Genital Tumors, 5th edition, states that p16 immunohistochemistry is an effective (yet flawed) indirect test for HR-HPV infection, in line with the STRs that state p16 is a valid test to determine HPV status and can be used to code HPV-associated and HPV-independent histologies. In this scenario, "negative for high-risk human papilloma virus (HR-HPV) on Pap smear" would be cytology-based, and may have missed cytologically malignant cells. A subsequent, more definitive biopsy was performed and was found to be strongly positive for p16, therefore, the tumor should be coded as 8483/3. |
