20210072 | Hormone Therapy--Breast: How are hormone therapy (HT) and other related data items coded when a patient had a previous breast primary and is still on HT when diagnosed with a new breast primary? See Discussion. |
In this scenario, we record that HT began for the second primary on the date of diagnosis, and the Systemic/Surgery Sequence ends up usually being coded 4 because the HT continues even if the specific agent may be changed. This does not seem to meet the definition of neoadjuvant therapy for the second primary so we approach the staging and grade coding as just clinical/pathological? For example, if the tumor size at surgery is a little larger than estimated on imaging, we would use the pathologic size for our staging. The tumor size and grade of the second primary are not being changed by the ongoing HT. Do we have the right approach? |
For this example: 1. Code HT as treatment on the date of diagnosis for the second primary. 2. Code Systemic/Surgery Sequence as 4. 3. Do not code neoadjuvant data items as neoadjuvant started/completed. The HT given would not qualify for neoadjuvant therapy since the intent of the HT was not neoadjuvant. The HT would affect the second primary, but it is still not neoadjuvant. 4. Code clinical and pathological tumor size accordingly, based on the imaging and the pathological findings. 5. Code Extent of Disease data items based on the pathological findings since pathological findings take priority over clinical and this is not neoadjuvant therapy. |

20200039 | EOD 2018/Summary Stage 2018--GIST: How should Extent of Disease (EOD) and Summary Stage be coded for a multifocal gastrointestinal stromal tumor (GIST)? See Discussion. |
Example: Patient is found to have a 9.4 cm GIST in the jejunum and 2 cm GIST in the stomach during resection, neither stated to be outright malignant. Similar to the instruction in SINQ 20190041, this case is coded as a malignant jejunal primary due to multifocal tumor. However, it is unclear how to account for the stomach tumor, or any other multifocal tumor for GIST, when coding EOD and Summary Stage. |
For this case, report each GIST diagnosis separately. This differs from SINQ 20190041 because in that case the stomach GIST was incidental and measured only 0.3 cm. Reporting these separately means that each one is no longer a multifocal tumor. If there is no other indication of malignancy for these, they would not be reportable if diagnosed in 2020 or earlier. For cases diagnosed 2021 or later, all GIST are reportable. Report this as two primaries. Use the new GIST schema for EOD and assign EOD Primary Tumor 100 for each. There is no mention of extension outside the primary site. Summary Stage is Localized for each. |

20091055 | Date therapy initiated/Systemic/Surgery Sequence--Breast: How are these fields coded when a patient has chemotherapy after a sentinel lymph node biopsy and has a lumpectomy after completing chemotherapy? See Discussion. | On 4-10-08 a patient underwent sentinel lymph node biopsies. This was followed by chemotherapy which started on 4-15-08. The patient subsequently underwent a lumpectomy on 11-10-2008. | For this case, code Date Therapy Initiated to the date of the sentinel lymph node biopsy [04102008]. Assign code 3 [Systemic therapy after surgery] in Systemic/Surgery Sequence. |

20091079 | Primary site--Bladder: What is the correct subsite for "interureteric ridge"? See Discussion. | Description: 4 mm nodule at base of bladder near interureteric ridge. | For this case, assign code C670 [Trigone of bladder]. The description for this case states that the tumor location is the base of the bladder. Base is a synonym for trigone. The interureteric ridge (or interureteric crest, or interureteric fold) is a fold of mucous membrane extending accross the bladder between the two ureteric orifices. The trigone is located below the interureteric ridge. |

20041060 | Reportability/Behavior Code--Melanoma: If a dermatologist states a "proliferation of atypical melanocytes confined to epidermis" is melanoma in situ, is it reportable to SEER? |
For this case only, it is reportable to SEER because the physician states that it is "melanoma in situ." The phrase "proliferation of atypical melanocytes confined to epidermis" alone is not reportable to SEER. This phrase means that there are a number of (proliferation) pigmented cells (melanocytes) not showing the normal cell structure (atypical). |

20120048 | MP/H Rules/Primary site: Can you clarify how you interpreted the term "synchronous" to appropriately code the primary site to C68.9 [urinary tract] for SINQ 20110119 and did not use that code for SINQ 20100025 when both cases used MP/H Rule M8 to determine the number of primaries? See Discussion. | In SINQ 20100025 a patient was diagnosed with multiple urinary system tumors over a year apart. Rule M8 applies (single primary) and the primary site was left coded to the original primary site, C65.9 [renal pelvis]. In SINQ 20110119 a patient is diagnosed with multiple urinary system tumors within a month of each other, again rule M8 applies (single primary) and the primary site was coded to C68.9 [urinary system, NOS].
In both cases, rule M8 applies. However, the tumors were not diagnosed synchronously (e.g., one month apart in one case and greater than one year apart in the other). When the SINQ answer states, "same time" or "synchronous" does this mean during the same event? If not, what is the time range for "same time" or "synchronous"?
Please clarify when it is appropriate to code the primary site to C68.9 [urinary system, NOS] for Rule M8 and when it is not. |
For the purpose of applying the MP/H rules, the term "synchronous" means that the two diagnoses occurred at the same time or less than or equal to 60 days apart.
The case in SINQ 20100025 was not synchronous. The first lesion in the renal pelvis [C65.9] occurred in 1/08 and the subsequent tumors were diagnosed in 5/09, more than one year apart. In this case, you do not go back to change the primary site code on the original abstract.
The case in SINQ 20110119 was diagnosed synchronously, the first lesion in the bladder [C67.9] was diagnosed in 11/09 and the second lesion in the renal pelvis [C65.9] was diagnosed in 12/09, less than 60 days apart. Because the lesions were synchronous, the primary site is coded urinary system, NOS [C68.9]. |

20230020 | First Course Treatment/Reason for No Surgery of Primary Site: How should Reason for No Surgery of Primary Site be coded for cases when surgery was planned but aborted due to extent of disease seen during planned procedure? See Discussion. |
Lung abnormality on imaging prompted diagnosis on subsequent biopsy and clinical staging was documented as cT1b N0 M0. There was an attempt at resection, but the patient was found to have chest wall involvement and the procedure was aborted. How would Reason for No Surgery of Primary Site be coded in these types of scenarios when the surgery is aborted and the treatment plan changes due to the extension seen during surgery? |
For the example provided: For 2023 cases and forward, if no part of the surgery was performed, code Surgery of Primary Site 2023 (NAACCR Item #1291) as code A000 or B000 (no surgical procedure of the primary site). Code Reason for No Surgery of Primary Site (NAACCR Item #1340) as code 2 (surgery of the primary site was not recommended/performed because it was contraindicated due to patient risk factors (comorbid conditions, advanced age, progression of tumor prior to planned surgery, etc.). In contrast, if any part of the surgery was performed, assign the Surgery of Primary Site 2023 (NAACCR Item #1291) code that best reflects the extent of the surgery performed. Code Reason for No Surgery of Primary Site (NAACCR Item #1340) as code 0 (surgery of the primary site was performed). Use text fields to record the details. For cases prior to 2023, apply the same approach using Surgery of Primary Site (NAACCR Item #1290) instead of Surgery of Primary Site 2023 (NAACCR Item #1291). |

20190106 | Tumor Size--Esophagus: Can information from the endoscopy procedure that implies a size of 3 cm for Tumor Size--Clinical be used for Esophagus? See Discussion. |
1-28-2018 CT Scan: 2.4 cm mass 2-15-2018 Endoscopy: Mass was present 22 to 25 cm. Biopsies were taken with cold forceps for histology; biopsy positive. |
For the case you describe, we would record the clinical tumor size stated on the CT report. The priority order for clinical tumor size is as follows. 1. Biopsy or operative (surgical exploration) report 2. Imaging 3. Physical exam We do not recommend coding tumor size based on an inferred tumor size from a description such as "Mass was present 22 to 25 cm." Look for an actual measurement of the mass, or a stated tumor size. Use text fields to record details. |

20190046 | Tumor Size/Bladder: The 2018 SEER Coding and Staging Manual says to use imaging over physical exam as priority for determining tumor size. If a bladder tumor is 4 cm visualized on cystoscopy, and is 2.8 cm on CT scan, which should be used as the clinical size? Is cystoscopy (endoscopy) a clinical exam or imaging? |
For the case described here, use the size from the CT scan. Physical exam includes what can be seen by a clinician either directly or through a scope. A tumor size obtained visually via cystoscopy is part of a physical exam. Therefore, the imaging (CT) tumor size is preferred. Use text fields to describe the details. |

20140064 | Reportability--Testis: Is a mature teratoma of the testis reportable? See discussion. |
Mature teratoma is listed as a benign neoplasm (9080/0) in the ICD-O-3. SINQ 20120085 references a NAACCR Webinar that indicated pure mature teratomas of the testis in adults are reportable. We are not aware of any further documentation of this change in reportability. When did mature teratomas of the testis for adults become reportable? What is the defined age range for "adult"? The original SINQ question above lists the 2012 SEER Manual as a Reference, however, no clarification or mention of this change in reportability was found in that manual. |
For testis, mature teratoma in an adult (post-puberty) is reportable because it is malignant (9080/3); however, mature teratoma in a child is benign (9080/0). The 2011 NAACCR webinar introduced this concept and it was documented in the 2012 SINQ question. You may use 2011 or 2012 as the date of this change. The next edition of the SEER manual will include reportability examples. |
