20230073 | First Course Treatment/Surgery of Primary Site--Liver/Intrahepatic Bile Ducts: For a liver/intrahepatic bile duct primary, is an alcohol embolization the same thing as a percutaneous ethanol injection (PEI)? See Discussion. |
For C220-C221 primaries, Surgery of Primary Site includes code A150 for Alcohol tumor destruction (percutaneous ethanol injection/intratumoral injection of alcohol/alcohol ablation). The SEER and STORE manuals also indicate that alcohol embolization should be coded as Other Therapy, code 1. We are trying to determine whether alcohol embolization should be coded under Surgery of Primary Site or Other Therapy. |
Code alcohol ablation under Surgery of Primary Site 2023. Code alcohol embolization as Other Therapy when tumor embolization is performed using alcohol as the embolizing agent. Alcohol ablation, also known as an ultrasound-guided percutaneous ethanol injection (PEI); is treatment that involves injecting concentrated alcohol directly into the tumor. Embolization uses special techniques to close off blood flow by introducing special medications or using other techniques designed to block blood vessels. Types of embolization are arterial embolization as with alcohol (ethanol), chemoembolization, and radioembolization. Refer to the current SEER Program Coding and Staging Manual when assigning surgery and embolization procedures. |

20220005 | Reportability--Ambiguous Terminology: Can the term “at most” preceding a statement of a reportable diagnosis be used to accession a case? See Discussion. |
A January 2022 endometrium biopsy and curettage both show final diagnosis of “mild cytologic atypia and glandular crowding, at most endometrioid intraepithelial neoplasia.” Any subsequent surgery path is unlikely to provide clarification. |
Do not report the case in this scenario based on the diagnosis alone of mild cytologic atypia and glandular crowding, at most endometrioid intraepithelial neoplasia. "At most" is not an ambiguous term for reportability. It appears that "at most" in this case refers to the worst possible option within other possible options (differential diagnosis). Differential diagnoses are "educated guesses" or hypotheses and are usually not reportable unless proven otherwise. As there is no clear statement of the diagnosis in this case, we recommend that you seek additional information, for example, clinical diagnosis, treatment, and patient care. |

20220016 | Histology--Thyroid: What is the correct histology code for a follicular carcinoma, minimally invasive, oncocytic variant of the thyroid? See Discussion. |
There is an ICD-O histology code for follicular carcinoma, minimally invasive (8335/3) as well as follicular carcinoma, oxyphilic cell (8290/3). Per SINQ 20150045, the term oncocytic is synonymous with oxyphilic in this context. The Multiple Primaries/Histology General Instructions and histology rules do not include the term “variant” as a term that can be used to code a further histologic subtype. The term “variant” can be used for the Other Sites (non-updated STR sites) when the ICD-O-3.2 (or ICD-O-3 for older cases) provides the term “variant” in the histology name. |
Code follicular carcinoma, minimally invasive, oncocytic variant of the thyroid to follicular carcinoma, oncocytic variant (8290/3). The term "variant" is commonly used in thyroid histologies and if appropriate, used to determine histology code. The WHO Classification of Tumors of Endocrine Organs, 4th edition, lists synonyms for 8290/3 as Hürthle cell carcinoma; oncoycytic carcinoma; oxyphilic carcinoma; follicular carcinoma, Hürthle cell type; and follicular carcinoma, oncocytic variant. |

20220014 | Surgery of Primary Site--Melanoma: How is Surgery of Primary Site coded when a path specimen is labeled as a “staged excision” for a cutaneous melanoma. See Discussion. |
Patient was diagnosed on biopsy with lentigo maligna melanoma of the nasal dorsum. The only available documentation of the subsequent surgery is a single pathology report with the nasal dorsum “staged excision (debulking specimen)” and four additional “staged excision” specimens of the same site. Is it safe to assume this is a Mohs surgery? Would it be safe to assume staged excisions of sites other than skin of face, are also Mohs surgery? |
Interpret a "staged excision" for cutaneous melanoma as a type of Mohs surgery. Skin surgery codes are currently under review and revision. Document details in available text fields. |

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. |

20220001 | Solid Tumor Rules (2022)/Histology--Bladder: Can the term configuration be used to code the more specific histology for bladder primaries diagnosed 2022 and later? See Discussion. |
In the September 2021 Urinary Sites Solid Tumor Rules update, the term configuration was removed from the “DO NOT CODE histology when described as” list. However, it was not added as a term that can be used to code the more specific histology for urinary tumors. Can configuration be used to code the more specific histology 8130 (papillary urothelial carcinoma) when the diagnosis is urothelial carcinoma, tumor configuration: papillary? |
Beginning with cases diagnosed 1/1/2022, the term "configuration" can be used to code histology for urinary sites only. At the request of the AJCC urinary experts, the instructions were changed to allow configuration to be used to code histology. |

20220047 | Solid Tumor Rules/Multiple Primaries--Head and Neck: Is a patient with 2020 neck mass, squamous cell carcinoma (SCC), p16-negative, who then had a biopsy of the right tonsil (C09.9) in July 2022, SCC p16-positive, one or two primaries? Is this coded to 8070/3 using pre-2022 rules or a new, second primary p16-positive, 8085/3. See Discussion. |
History provided by the oncologist Right neck mass since 2019; 04/07/20, initial biopsy p16-negative SCC, delay of treatment due to patient preference, agreed to biopsy of tonsil and work-up August 2022; right tonsil biopsy: p16-positive, G2 SCC, nodal mass at that time >6 cm with extensive extranodal extension, Stage III (cT2, cN3, cM0, p16-positive); based on this history, was staged as a tonsil primary and p16-positive. Patient details 1. March 2020, CT neck and chest revealed a 0.5 x 2.7 x 2.3 cm low-density necrotic nodal mass at right neck level 2 suspicious for metastatic disease. There was a slight asymmetric increased size of the right palatine tonsil. There are a few sub-4 mm pulmonary nodules which are nonspecific. 2. April 7, 2020, FNA of right neck mass with pathology revealed p16-negative SCC 3. April 20, 2020, PET/CT revealed 3 x 2 cm right-sided level 2 node with FDG avidity 4. May 5, 2020, flexible laryngoscopy showed no obvious primary lesion 5. May 2020, after evaluation by a medical oncology, patient declined any treatment 6. June 17, 2022, return visit in medical oncology after PET/CT demonstrates significant progression in the neck; patient definitively declines chemo, but would like surgical opinion. Now has more rapidly progressive disease with skin breakdown and weeping from malignant lesion right neck. 7. June 22, 2022, radiation oncology consultation 8. July 15, 2022, tonsil biopsy: Invasive squamous cell carcinoma, moderately differentiated with LVI, p16-positive 9. Patient now agreeing to treatment with radiation: Tooth extractions 8/30/2022, radiation planning 9/14/2022 10. Patient consulted with cancer specialist who explained surgery is not recommended given level of extranodal extension and risk of seventh cranial nerve paralysis and fistula formation with surgical excision and who recommended chemoradiation 11. September 9, 2022, patient presented for radiation CT simulation/treatment planning and informs treatment team. Patient declined/refuses concurrent chemotherapy despite recommendations from two cancer institutions. |
Abstract a single primary of the tonsil. The diagnosis date is April 7, 2020. Assign 8070/3 for the histology. Metastases were found in 2020 before the primary of tonsil was determined in 2022. The oncologist information confirms this. |

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. |

20220012 | EOD 2018/Lymph Nodes--Corpus Uteri: Are lymph nodes found on imaging post-surgery included in Extent of Disease (EOD) Regional Nodes if surgery is already completed? See Discussion. |
11/16/20: Patient diagnosed with endometrial cancer on by MRI of the pelvis; 11.5 cm uterine mass consistent with cancer with no lymphadenopathy. 1/6/21: Patient had a total abdominal hysterectomy/bilateral salpingo-oophorectomy and pelvic lymph node dissection. Operative report stated patient had mildly enlarged bilateral pelvic nodes. Path report: Endometrioid adenocarcinoma with invasion of the serosa. Five bilateral pelvic nodes were sampled and negative. Originally, staging had patient as node negative. 1/22/21: Patient had post op imaging done that showed metastatic retroperitoneal, aortocaval, and possibly left iliac lymph nodes. Physician changed staging to include the lymph node involvement. |
EOD includes all information available within four months of diagnosis in the absence of disease progression or upon completion of surgery(ies) in first course of treatment, whichever is longer. Since the imaging was within the four-month window, and the nodes could have been positive during surgery but not assessed by the surgeon, use the information from the imaging. Assign code 600 for EOD Regional Nodes for involvement of the aortocaval and retroperitoneal nodes (para-aortic nodes), size unknown. |

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." |
