20240026 | Update to Current Manual/Reportability--Pancreas: For cases diagnosed 2024+, is a diagnosis of pancreatic intraepithelial neoplasia II (PanIN II) reportable? If so, how should histology be coded? See Discussion. |
SEER Program Coding and Staging Manual: Reportability – Reportable Diagnosis List indicates pancreatic intraepithelial neoplasia (PanIN II) (C250-C259) is reportable. However, the ICD-O-3.2 lists “Glandular intraepithelial neoplasia, grade II” and “Glandular intraepithelial neoplasia, low grade” as histology code 8148 with behavior of /0 (benign). |
Do not report PanIN II. WHO Classification of Digestive Tumors, 5th edition, now categorizes PanIN into two categories, low grade (8148/0) and high grade (8148/2). PanIN grade I and PanIN grade II are categorized as PanIN low grade; PanIN grade III is categorized as PanIN high grade. We will update the Reportability section of the manual. |

20200040 | Reportability--Skin: Is pseudomyogenic hemangioendothelioma (PMH) reportable with morphology code 9133/3? See Discussion. |
According to the literature, PMH is a low-grade malignant vascular neoplasm of different tissue planes including skin and soft tissue. However, the references also state: PMH is a cutaneous tumor that behaves in an indolent fashion. There is no indication that this was a malignant diagnosis. 12/3/18 Foot, left skin lesion, punch biopsy: Superficial squamous epithelium demonstrating hyperkeratosis and fragments of keratin debris, no tumor seen. Foot, left skin lesion, punch biopsy: Pseudomyogenic (epithelioid sarcoma-like) hemangioendothelioma, see note. NOTE: The submitted immunohistochemical slides were reviewed. Positive and negative controls reacted appropriately. The tumor cells demonstrate immunoreactivity to CK AE1/AE3 and CK7. The CD31 immunoreactivity described in the report cannot be confirmed as only the positive control is submitted for review. The tumor cells are negative for desmin, CD45, CD68, S-100, CD34, SMA, CD20, and HHV8. The proliferative index via Ki-67 is approximately 10%. The morphology (described below) and immunohistochemistry performed are compatible with a pseudomyogenic hemangioendothelioma. 12/4/18 Final Pathologic Diagnosis: Foot, left bone lesion, biopsy: Pseudomyogenic (epithelioid sarcoma-like) hemangioendothelioma, see note. Note: The patient's imaging findings were reviewed in conjunction with this case, revealing numerous lytic lesions of the tibia, fibula, talus, tarsal, metatarsal, and phalangeal bones. Additionally, as per the medical record, also reviewed in conjunction with this case, there are lesions of the skin. Thus, an extensive immunohistochemical panel was performed in an attempt to support the morphologic findings in this case, which were morphologically similar to the patient's skin biopsy. The tumor cells demonstrate strong immunoreactivity to pancytokeratin (CK AE1/AE3) and vimentin with moderate immunoreactivity to Fli-1. The tumor cells demonstrate weak immunoreactivity to epithelial membrane antigen. INI-1 is retained. There is focal immunoreactivity to CD31 although this is limited to the edges of the tissue fragments. The tumor cells are negative for HHV-8, CD34, smooth muscle actin, CK8/18, desmin, CD99, and Bcl-2. The combination of morphologic (see below for microscopic description) and immunohistochemical findings are consistent with pseudomyogenic hemangioendothelioma. Fresh tissue was submitted for karyotype analysis at the time of intraoperative consultation; however, it revealed only a normal appearing male karyotype. Thus, molecular confirmation was sought. The original slides and a paraffin block were submitted for FOSB rearrangement analysis, as pseudomyogenic hemangioendothelioma is known to have recurrent rearrangements with FOSB. Additional immunohistochemistry performed at (FACILITY) demonstrating immunoreactivity for ERG, supporting a vascular origin for this neoplasm. Fluorescence in situ hybridization demonstrated that 13% of the cells examined show FOSB rearrangement. While this FISH probe is for investigational purposes, the above findings support the diagnosis of pseudomyogenic hemangioendothelioma. |
Do not report PMH. The WHO Classification of Skin Tumors lists pseudomyogenic hemangioendothelioma as a borderline malignancy (9138/1). Borderline malignancies of the skin are not reportable. |

20210033 | Reportability--Liver: Is a diagnosis of Liver Imaging Reporting and Data System (LI-RADS)-Treatment Response (LR-TR) viable nodule seen on imaging and treated with Y-90 radiotherapy reportable? See Discussion. |
Patient was initially diagnosed in 2017 with LR-5 lesions in segments 3 and 7 of liver and treated with radiofrequency ablation (RFA). Routine scans in 2019 show no evidence of residual or recurrent disease. Surveillance imaging in 2020 identifies LR-TR viable segment 3 treatment zone with slowly growing arterially-enhancing nodule as well as increasing arterial enhancement in the neighboring parenchyma. No new LR-4 or LR-5 observations. Patient is not a surgical candidate but is treated with Y-90 radiotherapy. Per Rule M10, tumors diagnosed more than 1 year apart are multiple primaries. However, there is no clear clinical statement of malignancy in this case. |
Do not report LR-TR viable as a new primary. LR-TR viable is a component of the Li-RADS Treatment Response algorithm designed to assess response for path-proven or presumed (e.g., LR-4, LR-5, LR-M) malignancy after locoregional treatment for hepatocellular cancer. LR-TR viable indicates it met the criteria as a viable tumor. |

20160039 | First course treatment/Surgery of Primary Site: If a procedure stated to be an "excisional biopsy" doesn't grossly remove the tumor, should Surgery of Primary Site be coded as an excisional biopsy? See Discussion for example. |
Would you code an excisional biopsy as Surgery for the following case?
The patient presented with a large protruding polypoid anal canal mass. The diagnosis of malignancy was made following a procedure referred to by the surgeon as an excisional biopsy. The protruding portion of the anal canal mass was excised, but the deep margin was grossly involved. The PE exam after the "excisional biopsy" found a firm mass, 4 cm in length on DRE. Further work-up with imaging showed gross residual disease extending to adjacent skeletal muscle (external anal sphincter). Although the internal/protruding anal canal portion of the tumor was excised, there was clearly extensive residual tumor. The patient underwent definitive concurrent chemoradiation only; subsequent surgery was not planned or performed. |
Do not record this excisional biopsy as surgery because there was residual macroscopic tumor. See Note 1 under #4 on page 130 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf |

20160077 | First course treatment/Immunotherapy--Prostate: Is XGEVA, given for bone mets from prostate cancer, abstracted as immunotherapy, or is it an ancillary drug and not recorded? |
Do not record XGEVA when given for bone mets from prostate cancer. See SEER*Rx for more information.

20160062 | Grade--Kidney: Should WHO/ISUP grade for renal cell carcinoma be coded for cases diagnosed 2016 and later? See discussion.
|
The 2016 WHO Classification of Tumours of the Urinary System appears to be moving away from using Fuhrman grading toward using WHO/ISUP grade. These seem like similar 4 grade staging systems; however, the SEER Manual specifically states to not use the Special Grade System table for WHO/ISUP. We are seeing the WHO/ISUP grade being used on 2016 pathology reports.
Examples of new grading for renal cell carcinomas Histologic type: Clear cell renal cell carcinoma Histologic grade (WHO/ISUP 2016): Grade 3 in a background of 2 (of 4). And Histologic type: Clear cell renal cell carcinoma Histologic grade (ISUP): Grade 2. |
Do not record WHO/ISUP grade in the grade/differentiation field.
Designated fields for this grade system are being proposed for future implementation. |

20190036 | First Course of Treatment/Hormone Therapy--Breast: Is hormone therapy (HT) prescribed for invasive ductal carcinoma of the right breast coded as treatment for lobular carcinoma in situ (LCIS) of the left breast even though the treatment plan for the LCIS was documented as surveillance? See Discussion. |
Patient is diagnosed with invasive ductal carcinoma (IDC), right breast, receives HT, radiation therapy, and surgery. The same patient is diagnosed with LCIS, left breast one month later--recommend surveillance only (no surgery). Is the HT for the left breast coded at all? I think for COC/NCCN, we do not, but for SEER what would I do? Treatment in the SEER Manual 2018 states, "Code the treatment on each abstract when a patient has multiple primaries and the treatment given for one primary also affects/treats another primary." The example include bladder/prostate and ovarian/cervix. It also states, "Code the treatments only for the site that is affected when a patient has multiple primaries and the treatment affects only one of the primaries." The example includes colon/tonsil. Breast LCIS treatment appears complicated. Per NCCN guidelines, this condition no longer has recommendations, however it appears as though they still state that if a core biopsy is done and is LCIS, follow up should be ultrasound or surgical excision. Nowhere does it state hormone is recommended. |
Do not code the hormone treatment for the LCIS since it was clearly documented that the hormone treatment was given for the IDC and the treatment for the LCIS was documented as "surveillance." Use text fields to record the details on both abstracts. |

20031054 | Grade, Differentiation: Is grade always coded to 4 for a diagnosis of Ewing's sarcoma? | Do not code the ICD-O-3 grade for Ewing sarcoma unless documented in the record. In the TNM system, grade is required to place Ewing sarcoma into a stage group. For TNM staging purposes, Ewing sarcoma is classified as G4. Do not apply TNM rules to ICD-O coding. |

20170020 | Size of tumor--Breast: Please clarify guideline #7 if the only size you have is from a CORE biopsy specimen and imaging only states nonspecific sizes, like "architectural distortion" or "calcifications" and a core biopsy pathology reports invasive tumor spans 5mm. Do you use the core biopsy size, or use 999 for clinical tumor size? See discussion. |
SEER Program Coding and Staging Manual 2016 states: Record size in specified order using a. The largest measurement of the primary tumor from physical exam, imaging, or other diagnostic procedures before any form of treatment. See Coding Instructions 7-9 below. b. The largest size from all information available within four months of the date of diagnosis, in the absence of disease progression when no treatment is administered. #7 Priority of imaging/radiographic techniques: Information on size from imaging/radiographic techniques can be used to code clinical size when there is no more specific size information from a biopsy or operative (surgical exploration) report. It should be taken as a lower priority, but over a physical exam. |
Do not code size of tumor based on the size of the core biopsy. If the statement "invasive tumor spans 5mm" from the core biopsy report represents the surgeon's assessment of tumor size, use this information to code tumor size when no other information is available. |

20021162 | Chemotherapy: Should radiosensitizing chemotherapy agents (i.e., drugs typically coded as treatment for cancer) be coded as treatment when they are given in combination with radiation therapy with the intention of enhancing that treatment? See discussion. |
Per our consultant, these drugs are given at a lower dose than that typically given to treat cancer patients. |
Do not code radiosensitizers and radioprotectants as cancer-directed therapy. Drugs typically classified as chemotherapy agents would be "ancillary drugs" for the purpose of coding cancer-directed therapy because the drugs are given at a much lower dosage than that typically given to treat cancer patients. Per Book 8, ancillary drugs are not to be coded as cancer-directed therapy. Radiosensitizers and radioprotectants do not work directly on the cancer and are not coded under any of the systemic therapy fields. |
