20220049 | Solid Tumor Rules/Multiple Primaries--Lung: How many cases should be abstracted for a patient with 2022 wedge biopsy of right upper lobe acinar predominant lung adenocarcinoma and wedge biopsy of right lower lobe lepidic predominant adenocarcinoma if there is concern for diffuse spread throughout the lungs secondary to the lymphangitic carcinomatosis and possible diffuse pneumonic type of adenocarcinoma? See Discussion. |
Acinar predominant adenocarcinoma measures at least 12 mm and involves wedge biopsy margins, while the lepidic predominant adenocarcinoma measures 11 mm and does not involve the margins of that separate specimen. Pathologist also notes, “CT findings of diffuse coarse reticular nodular opacity, these findings may represent pneumonic type adenocarcinoma/diffuse pulmonary involvement or intrapulmonary metastasis. Both of these scenarios have the corresponding stages of pT4 (if thought to be ipsilateral) or M1a (if thought to also involve the contralateral lobe).” Patient declined any further treatment and transitioned to hospice before expiring less than 1 month after wedge biopsies. It is unclear if Rule M6 would apply to these two specimens with different subtypes since this scenario is not specifically addressed in the M rule definitions. |
Abstract two separate primaries when separate/non-contiguous tumors are two or more different subtypes/variants in Column 3 of Table 3 using Rule M6 in the Solid Tumor Rules (September 2021 Update). They represent two subtypes/variants of the same NOS histology. When coding histology, tissue from pathology takes precedence over imaging, including when stated as differential diagnoses based on the CT scan, as noted by the pathologist in this example. |

20220043 | First Course Treatment/Neoadjuvant Therapy--Melanoma: How are the three Neoadjuvant Therapy data items (Neoadjuvant Therapy, Neoadjuvant Therapy--Clinical Response, Neoadjuvant Therapy--Treatment Effect) coded when a patient is diagnosed with melanoma in the lymph nodes with no primary skin site identified? The physician gives immunotherapy as neoadjuvant therapy with planned and carried out surgical resection of involved lymph nodes following completion of immunotherapy. There is no "planned definitive surgical resection of the primary site" as no primary site was found, |
Assign code 0 to each of the three Neoadjuvant Therapy data items in this situation. We will add an example to the coding instructions for these data items in the next release of the 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. |

20220003 | Reportability/Histology--Anus: Are 2021 diagnoses of anal intraepithelial neoplasia (AIN) II or AIN II-III reportable in patients with a known history of AIN II or AIN II-III diagnosed prior to 2021? See Discussion. |
Patient has a history of AIN I/low-grade squamous intraepithelial lesion (LSIL) dating back to at least 2015, was diagnosed with AIN II-III in 12/2019, and then diagnosed again with AIN II-III in 08/2021. There is no indication of treatment or a disease-free interval for this patient. SINQ 20210015, while not an exact match to this case, implies there is no clear disease-free interval for these AIN diagnoses, so it is the same non-reportable neoplasm diagnosed prior to reportability (12/2019). However, there was a diagnosis of a reportable neoplasm in 2021, so it also seems possible this would be accessioned as a reportable tumor based on a diagnosis of reportable tumor diagnosis in 2021. With the reportability changes for these intraepithelial neoplasia II/II-III tumors, these situations will arise more frequently. |
Report AIN II and AIN II-III cases when initially diagnosed in 2021 or later. Do not report retrospective cases; that is, cases with diagnoses prior to 2021 with continuation of AIN II or AIN II-III extending into the reportable period. |

20220022 | Tumor Size--Pathologic--Anus: In 2019, the pathology report of an anal canal squamous cell carcinoma stated the tumor size is 2.5 cm from proximal to distal (3.5 cm in circumference). Is the pathologic tumor size tumor size 025 or 035? |
Based on the information provided, code the tumor size as 035. We asked an expert pathologist to review this question and she said to use the larger measurement. She also said "the pathologist usually cuts the anus and rectum open like a tube; the “circumference” would be measured flat." |

20220033 | When coding the Covid testing results, does SEER have any guidance on whether or not at home tests fall within reportability? For instance, if a medical provider says pt tested positive on an at home test, do we record that? |
When you have information about home COVID tests, record this information. For example, if the home test was positive record as follows: COVID-19 rapid viral antigen test POS 08/09/2022 |

20220002 | Solid Tumor Rules (2018, 2021)/Histology--Cervix: For cases diagnosed 1/1/2022 and later, how is histology coded for the following three cervix cases relating to p16? See Discussion. |
The 2022 SEER Manual indicates the p16 status (positive or negative) can be used to code more the specific histology for squamous cell carcinoma, human papilloma virus (HPV) positive (8085) and squamous cell carcinoma, HPV negative (8086). However, the histology coding instructions in the Other Sites schema have not been updated and the 2022 SEER Manual does not cover all situations commonly encountered in the registry. Does the clarification regarding p16 apply to these other situations?
|
For cases diagnosed beginning 1/1/2022, assign histology based on new codes and terms for the examples of cervical cancer using the available p16 results as follows. 1. Adenocarcinoma, HPV-independent, NOS (C53._) (8484/3) 2. Carcinoma, squamous cell, HPV-associated (C53._) (8085/3) 3. Carcinoma, squamous cell, HPV-independent (C53._) (8086/3) The 2022 SEER Manual states: Beginning with cases diagnosed 01/01/2022 forward, p16 test results can be used to code squamous cell carcinoma, HPV positive (8085) and squamous cell carcinoma, HPV negative (8086). Use the available results as the rules for Other Sites have not been updated yet. The SSDI Manual data item p16 for Cervix schema also states that p16 is based on testing results and not a physician statement. We can address these situations in a future version of the Solid Tumor Rules. The Other Sites rules will provide document priority when coding hsitology: biopsy vs. resection, cytology vs. histology, primary site vs. mets or regional site. |

20220046 | First Course Treatment/Immunotherapy--Other Therapy: Should IMC-A12 (Cixutumumab) be coded as Immunotherapy/Biological Response Modifier (BRM) treatment? See Discussion. |
IMC-A12 (Cixutumumab) is listed as a BRM agent in SEER*Rx, but the Remarks section indicates it should be coded as Other Therapy until there is FDA approval. It is unclear if FDA approval was ever given for this agent. We are mainly seeing it given for prostate primaries. |
Code Cixutumumab as Other Therapy. Cixutumumab is still in clinical trials and not approved by FDA yet. Though it is classified as an immunotherapy agent, it is not approved. |

20220013 | Reportability/Histology--Kidney: What is the histology and behavior of a papillary renal neoplasm with reverse polarity? See Discussion. |
Patient had a partial nephrectomy with final diagnosis of papillary renal neoplasm with reverse polarity. Diagnosis comment states: Papillary renal neoplasm with reverse polarity is currently considered to be a histologic variant of papillary renal cell carcinoma; however, recent studies suggest that it has a very indolent clinical behavior. |
Report papillary renal neoplasm with reverse polarity as 8260/3. According to the WHO Classification of Urinary and Male Genital Tumors, 5th edition, this is a distinctive pattern of papillary renal cell carcinoma that has been recently recognized. These tumors have recurrent mutations of KRAS, differing from typical papillary renal cell carcinoma. We recommend that you include with reverse polarity in your histology text to differentiate this entity from others classified in 8260/3. |

20220018 | Solid Tumor Rules/Histology--Thyroid: What is the correct histology code for the following thyroid primary with multiple tumors abstracted as one primary diagnosed prior to 2021? See Discussion. |
2016 Total thyroidectomy, Multifocal -Dominant Tumor: Right Lobe, Papillary thyroid carcinoma (8260/3) -Tumors two through five: Three tumors Papillary thyroid carcinoma (8260/3), and one tumor Papillary thyroid carcinoma, follicular variant (8340/3) -An additional tumor: Non-invasive follicular thyroid neoplasm with papillary-like nuclear features (8343/2) |
Code this multifocal thyroid carcinoma, single primary, as papillary thyroid carcinoma, follicular variant (8340/3) using Solid Tumor Rules, Other Sites, Rule H13 that says to code the most specific histologic term. We consulted with our endocrine specialty pathologist and when there is a mix of papillary and follicular variants, assign 8340. Non-invasive follicular thyroid neoplasm with papillary-like nuclear features is coded as 8349/1 beginning in 2021. According to the WHO Classification of Endocrine Organs, 4th edition, it was formerly classified as non-invasive encapsulated follicular variant of PTC (FVPTC) (8343/2) but was reclassified based on extremely low malignant potential. |
