20081114 | Reportability--Brain and CNS: Is hygroma reportable? See Discussion. |
Benign brain guidelines indicate that named tumors that have been assigned an ICD-O-3 code are reportable. However, per I&R: "Most cystic hygromas (9173/0) are fetal malformations and occur in patients less than two years old. If this patient was an adult, they are primarily treated with surgery. Hygroma (used in a general sense) is a response to trauma (i.e., subdural hematoma) and as such, is not a "new growth" and would not be reportable either as a cyst or as a neoplasm. Unless the patient had some sort of operation, I'd hesitate to include the case as a reportable benign tumor." How is the cancer registrar to distinguish between reportable and non-reportable hygromas? Example: Brain MRI showed diffuse cerebral volume loss and incidental bilateral frontal subdural hygromas (histology code 9173/0). Reference: I&R 14825 |
Hygromas are not reportable. This instruction will be added to the next revision of the benign brain rules. According to an expert in the field, hygromas are not neoplastic. Hygromas are cystic dilations of a localized subarachnoid or subdural accumulation of clear fluid related to an excess accumulation of CSF, typically related to an old hemorrhage that somehow prevents reabsorption of CSF. |

20130022 | Reportability--Melanoma: Is "early" melanoma reportable? See Discussion. |
Because "evolving" melanoma was never reportable, this issue only relates to "early" melanoma. |
For cases diagnosed 2018 to 2020, early or evolving melanoma is not reportable. Evolving melanoma (borderline evolving melanoma): Evolving melanoma are tumors of uncertain biologic behavior. Histological changes of borderline evolving melanoma are too subtle for a definitive diagnosis of melanoma in situ. The tumors may be described as "proliferation of atypical melanocytes confined to epidermal and adnexal epithelium," "atypical intraepidermal melanocytic proliferation, "atypical intraepidermal melanocytic hyperplasia"; or "severe melanocytic dysplasia." Not reportable. Melanoma Solid Tumor Rules, 2018, page 3, https://seer.cancer.gov/tools/solidtumor/Melanoma_STM.pdf |

20240033 | Solid Tumor Rules/Multiple Primaries--Stomach: Is a carcinoid tumor of the stomach diagnosed on 01/01/2023, on a patient who was followed up by Gastrointestinal (GI) and was found to have another stomach carcinoid on 02/01/2024, one primary or two? See Discussion. |
Based on the Solid Tumor Rules, we would make this two since it is over one year. According to a previous SINQ question 20110046, we are to code this as one primary. We see patients come back with multiple carcinoid tumors over the years and would like clarification. |
Stop at the first rule that applies which is M12. Per note 3: When it is unknown/not documented whether the patient had a recurrence, use date of diagnosis to compute the time interval. This means there are two primaries. There is a genetic syndrome that causes multiple carcinoid tumors in the GI tract, per our GI expert, and they should be treated as new primaries per M12. SINQ 20110046 describes a unique situation whereby the subject matter expert felt that the occurrence of multiple tumors was due to an unknown underlying condition driving the proliferation of neuroendocrine cells. |

20230063 | EOD 2018/EOD Regional Nodes--Melanoma: Can central cancer registries code Extent of Disease (EOD) Regional Nodes as 000 based on Breslow’s depth and/or Clark’s Level (per EOD and/or Summary Stage) from a melanoma pathology only report with a localized tumor and no information on regional lymph nodes or mets. See Discussion. |
Based on the EOD General instructions for accessible sites, the following three requirements must be met a. There is no mention of regional lymph node involvement in the physical examination, pre-treatment diagnostic testing, or surgical exploration; b. The patient has localized disease; c. The patient receives what would be the standard treatment to the primary site (treatment appropriate to the stage of disease as determined by the physician), or patient is offered usual treatment but refuses it. As a central registry, we receive a lot of melanoma path reports but never receive an abstract since the patients are seen at a dermatology office that does not report to the central registry. In these scenarios, we have both the diagnosis and wide excision or Mohs surgery from which we create a consolidated record. It is not often that lymph nodes are removed which indicates there were no palpable nodes. Since the Breslow’s and Clark’s level allow for summary staging, is it possible to have central registry guidelines that allow for coding lymph nodes other than 999? The path reports meet two of the three criteria. Is there any new literature that supports coding lymph nodes 000 based on a Clark’s level or Breslow measure providing the patient has a wide excision? |
Assign 000 for EOD Regional Nodes when you have a pathology only report with a localized tumor based on Breslow’s depth and/or Clark’s Level (per EOD and/or Summary Stage) and no information on regional lymph nodes or mets. When the tumor is noted to be regional or distant based on Breslow’s Depth and/or Clark’s based on the definitions in EOD and/or Summary Stage, do not assume that the nodes are negative and assign 999. Clarification will be added to the EOD manual. |

20220041 | Primary Site/Histology--Intrahepatic Duct: How are primary site and histology coded for cholangiocarcinoma cases when the pathology only shows a liver tumor and other involvement. See Discussion. |
A common scenario is a patient has a positive CT of the abdomen/pelvis for liver mass only. Biopsy of the liver mass is positive for cholangiocarcinoma. The physician is also calling the liver tumor the primary site with histology of cholangiocarcinoma. There is no evidence of intrahepatic bile duct (C221) or gallbladder (C240) involvement which are sites specific to this histology. The hematology/oncology consult stages this as Stage IIIA, T3N0M0 intrahepatic cholangiocarcinoma. Can we code cholangiocarcinoma with site code C220 (liver) or should we assume that C221 (intrahepatic bile ducts) would be a better code to reflect this histology? |
Assign C221 (intrahepatic bile duct) as the primary site for cholangiocarcinoma (8160/3). Our expert GI pathologist confirms that even when intrahepatic bile ducts are not specifically mentioned, intrahepatic cholangiocarcinoma originates in the intrahepatic bile ducts. |

20210011 | Primary site: Is C720 the correct primary site for a diagnosis of a paraspinal neuroblastoma on autopsy in a nine month old with Noonan syndrome? See Discussion. |
Autopsy/Pathology Report (2020) excerpts External Examination Nervous System: There is an 8.5 cm mass located in the right thoracic paraspinal area. Final Anatomic Diagnosis Clinical History: Paraspinal mass suspicious for neuroblastic tumor (detected by imaging studies) Nervous System: Right thoracic paraspinal neuroblastoma, poorly differentiated |
Assign primary site code C473 for this case based on the information provided (peripheral nerves and autonomic nervous system of thorax). From our expert pathologist consultant: The origin of neuroblastomas is generally in the adrenal medulla or one of the sympathetic ganglia on either side of the vertebral column (although they have been reported in many other locations given the migration of the neural crest cells embryologically). |

20170031 | MP/H Rules/Multiple primaries--Penis: How many primaries should be reported for a diagnosis of invasive squamous cell carcinoma (SCC) of the penis in 6/2011, treated with excision and fulguration followed by 10/2014 penile lesion found to be SCC with basaloid features focally highly suspicious for invasion? Clinically, the 2014 tumor is stated to be in situ and recurrent penile cancer and follow-up in 2/2015 indicates there was no evidence of tumor following treatment. Subsequently, in 3/2016 the patient has another penile lesion biopsy showing SCC in situ suspicious for invasion, clinically stated to be recurrent. See Discussion. |
At the central registry, we have accessioned this scenario as three primaries per Multiple Primaries/Histology (MP/H) Rule M10 (diagnosed more than 1 year apart), as the patient was stated to be disease free between each occurrence. However, the diagnosing/treating facility is not reporting these cases due to clinical statements of recurrent disease. This is an example of a case type identified on casefinding audits conducted by our central registry in which we have learned SEER's expectation of MP/H rule application does not match hospital reporting. Can the 2018 version of the MP/H rules more clearly address how this type of clinically recurrent (multiple times) case should be handled? |
Accession three tumors as the tumors were each diagnosed more than one year apart according to the MP/H Rule M10 for Other Sites. And, as you have noted, the patient was free of disease after each diagnosis. The MP/H rules have very clear instructions regarding the word "recurrence." See page 10, specifically A.7., https://seer.cancer.gov/tools/mphrules/2007_mphrules_manual_08242012.pdf SEER will evaluate the MP/H rules in the upcoming revision. |

20150025 | Primary Site--Lung: What are the guidelines for coding primary site when a lung tumor is described as a hilar mass? See discussion. |
At a recent meeting, one registry stated that they apply the following guidelines. 1) If the tumor is described as a hilar mass and there is no mention of LN involvement, Primary Site is coded to hilum (C340) 2) If there is LN involvement along with the mention of a hilar mass, then Primary Site is coded to C349 |
Assign primary site code C340 when a lung tumor is described as a hilar mass. |

20021147 | Other Cancer Directed Therapy--Hematopoietic, NOS: Is "aspirin" treatment for primary polycythemia? See discussion. |
Aspirin is listed as treatment for "thrombocythemia" in the Abstracting and Coding Guide for the Hematopoietic Diseases but not for "primary polycythemia." |
Do not code aspirin as treatment for primary polycythemia (polycythemia vera). |

20160033 | First course teatment/Surgery of Primary Site: Is microwave ablation (using heat not alcohol) coded to a surgery code? See Discussion. |
As of 2013, radiofrequency ablation is coded to "radiation therapy," chemoembolization is coded to "chemotherapy," and microwave ablation code to "other." Or, is coding microwave ablation (using heat not alcohol) coded to surgical code "16"? The latest documentation year that I could find in the SEER website regarding the above was 2013. I would appreciate clarification/confirmation of correct coding especially for microwave ablation. |
According to a consensus answer of the technical advisory group, a small group of representatives from each standard setter that meets periodically, microwave tumor ablation should be coded as surgery. For liver, assign code 16 (Heat-Radio-Frequency ablation (RFA); for kidney, assign code 15 (Thermal ablation). |
