20091021 | Behavior/Reportability--All sites: Would a GIST tumor stated to be "high risk for malignant behavior" be a reportable GIST? See Discussion. |
According to our pathologist and oncologist, the terms "malignant" and "benign" do not apply to GIST. Rather, the term "high risk for malignant behavior" is used. This is based on tumor size: greater than 5 cm and mitotic activity: greater than 5 mitoses/50 hpf. |
Do not report the case to SEER if it does not satisfy the criteria for reportability. According to the current reportability criteria, malignant GIST (8936/3) is reportable to SEER. GIST coded to 8936/0 or 8936/1 is not reportable. If your pathologist will not indicate "malignant" or "benign," code 8936/1 applies according to ICD-O-3 and, therefore, these are not reportable to SEER. |

20230050 | Reportability/Histology--Soft Tissue: Is a diagnosis of Myofibroblastoma with sarcomatous transformation a reportable malignancy? See Discussion. |
Patient was diagnosed in September 2022 via excision of a 12 cm pelvic mass with final diagnosis of Myofibroblastoma with sarcomatous transformation. Diagnosis comment states, “Most of the tumor is composed of conventional features of myofibroblastoma. However, a focal area demonstrates increased cellularity, fascicular growth and increased mitotic activity (up to 11 per 10 hpf), consistent with sarcomatous transformation (morphologically low to intermediate grade).” Is this sarcomatous transformation describing a malignant transformation from an otherwise benign histology? If so, how should histology be coded in this case? |
Do not report the case. The histology is 8825/0 based on the example provided and not reportable. Myofibroblastoma with sarcomatous transformation is a rare, benign condition, sometimes referred to as sarcomatous features. A malignant tumor would be referred to as a myofibroblastic sarcoma. |

20180081 | Reportability--Corpus uteri: Is endometrial atypical complex hyperplasia/borderline endometrial adenocarcinoma (FIGO 1), (mucinous type), (no invasion of myometrium) reportable? |
Do not report this case based on the information provided. The actual diagnosis is somewhere between atypical hyerpplasia and carcinoma in situ. Do not report until/unless a more definitively reportable diagnosis is made. |

20210053 | Reportability/Heme & Lymphoid Neoplasms: Is ALK positive (ALK+) histiocytosis involving the bone marrow and kidney reportable? See Discussion. |
2021 Bone marrow biopsy showed erythroid hyperplasia, increased histiocytes with hemophagocytosis and Factor XIIIa positive histocytic cells. Moderate cytoplasmic staining for ALK 1, consistent with bone marrow involvement of ALK-positive histiocytosis. A subsequent kidney lesion biopsy was also found to have ALK-positive histiocytosis. The patient was then treated with clofarabine. Patient is 3 years old. 07/2020-Chart indicates patient presented in June with fevers and refusing to walk with pancytopenia, bone marrow biopsy showed no leukemia buthistiocytes. Impression: ALK positive histiocytosis involving BM and kidney. 10/2020 Bone marrow final diagnosis states right and left bone marrow aspirates and biopsies: No morphologic or immunohistochemical evidence of involvement by the patient's previously diagnosed ALK+ histiocytosis (see Comments) - Multiple histiocytic collections with prominent hemosiderin; favor reactive - background normocellular bone marrow with maturing trilineage hematopoiesis. The patient's prior bone marrow samples are reviewed (9/2020 and 7/2020). Similar to the September bone marrow sample, the current marrow shows numerous histiocyte collections with abundant associated hemosiderin deposition. These histiocytes have a stellate/dendritic appearance and lack the atypical features noted in the patient's marrow at diagnosis, favoring a reactive process. This impression is further supported by the lack of immunoreactivity for either Factor XIIIa or ALK1 among these cells. There is no convincing morphologic or immunohistochemical evidence of marrow involvement by the patient's previously diagnosed ALK+ histiocytosis within the sampled material. Of note, the marrow otherwise appears normocellular for the patient's age, indicative of ongoing marrow recovery post therapy. It is not clear whether this would be equivalent to Langerhans cell histiocytosis, disseminated (9751/3) as there is not a statement of Langerhans cell or whether this is just histiocytosis, NOS and not reportable. |
Do not report this case of histiocytosis. Based on the information provided, this case is not reportable. |

20130186 | Grade: Can the FIGO grade be used to code the morphologic grade? See discussion. |
FIGO Grade is coded in CS SSF 7 in the Corpus Uteri schema. The SEER Manual does not address using FIGO grade for coding grade in morphology. |
Do not use FIGO grade to code the grade field. See the sentence below the table in Instruction #6 in the Grade Coding Instructions for cases diagnosed 2014 and later, http://seer.cancer.gov/tools/grade/ |

|
20180037 | Date of Diagnosis--Colon: If a patient has a positive Cologuard test, is the date of diagnosis the date of the cologuard test or the date of the biopsy? |
Do not use the date of a positive Cologuard test as the date of diagnosis. |

20200053 | Solid Tumor Rules (2018)/Multiple primaries--Bladder. Would the metastatic diagnosis indicate a new primary? If the metastatic diagnosis indicates a new primary, would the primary site be C688 and date of diagnosis 11/14/18? See Discussion. |
7/8/16 Urinary bladder, biopsy: Non-invasive low grade papillary urothelial carcinoma. Muscularis propria (detrusor muscle) is not identified. 9/2/16 Urinary bladder, bladder tumor, transurethral resection: High grade papillary urothelial carcinoma. No definite invasion identified. Muscularis propria (detrusor muscle) is identified and not involved by tumor. 1/7/17 A\S\Bladder: Noninvasive low grade papillary urothelial carcinoma. Granulomatous cystitis, consistent with BCG (Bacillus Calmette-Guerin) treatment. Lamina propria is not involved with tumor. Detrusor muscle is not identified. 4/4/17 Dome: Papillary urothelial carcinoma, low grade. No evidence of invasion. Muscularis propria is not present. Patient is clearly followed for at least a year but no further information until 19 months later, 11/14/18, when biopsy of lung indicates metastatic disease. 11/14/18 Lung, right lower lobe, mass, biopsy: Metastatic urothelial carcinoma. Immunohistochemical analysis results (CK7 positive, CK20 focally positive, P63 positive, GATA3 positive, TTF1 negative and NAPSIN-A negative) support the diagnosis |
Do not use the solid tumor rules to assess the 2018 diagnosis. See Note 1 on page 20 of the Urinary Sites Solid Tumor Rules, https://seer.cancer.gov/tools/solidtumor/Urinary_STM.pdf The 2018 diagnosis proves that this patient had invasive bladder cancer. Change the behavior on the abstract to /3 and use text fields to record the details. |

20110048 | First course treatment--Heme & Lymphoid Neoplasms: How is a "donor lymphocyte infusion" that is used in the treatment of CLL coded? | Donor lymphocyte infusion (DLI) is coded as immunotherapy. The lymphocytes are donated by the same person who donated the original stem cell transplant. The lymphocyte infusion creates an immune response in which the T-cells are activated to attack the cancer cells.

20230035 | Update to Current Manual/2018 EOD Manual/EOD Primary Tumor--Bladder: According to the American Joint Commission on Cancer (AJCC), a transurethral resection of the bladder (TURB) cannot make a distinction between involvement of the superficial muscle-inner half (Stage T2a) and the deep muscle-outer half (Stage T2b). Is this same criteria applied to Extent of Disease (EOD)? |
EOD follows AJCC criteria in this situation and we have confirmed with AJCC that Stage T2a (superficial muscle) and Stage T2b (deep muscle) cannot be assigned when only a TURB is done. For EOD Primary Tumor, Bladder, codes 200, 250, 300, 350, can only be used when
If a TURB is done and there is mention of the muscularis propria invasion (superficial muscle or deep muscle), use EOD codes 370 or 400. If a TURB is done and the pathology report states superficial or deep muscle, ignore and coded as “invasion of muscularis propria, NOS” (EOD codes 370 or 400). Instructions and code descriptions for EOD Primary Tumor have been updated to indicate this. These updated instructions and code descriptions will be available when SEER*RSA is updated for 2024, Version 3.1 (Sept/Oct 2023). These updates are included here for reference and can be applied for cases diagnosed 2018+. |

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. |
