20180062 | Histology--Heme & Lymphoid Neoplasms: How is histology coded when a lymph node excisional biopsy shows Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL), predominantly in diffuse T-cell histiocyte rich large B-cell lymphoma-like (THRLBCL) pattern. Comment states: The findings are that of nodular lymphocyte predominant Hodgkin lymphoma with diffuse T-cell rich pattern (T-cell/histiocyte-rich large B-cell lymphoma-like). This variant is regarded as clinically more advanced. See Discussion. |
It appears an argument could be made for both NLPHL (9659/3) and THRLBCL (9688/3). We favor coding NLPHL (9659/3) because the pathologist did specifically call this a Hodgkin lymphoma, and also specified that it only has a T-cell/histiocyte-rich large B-cell lymphoma-like pattern. |
Assign histology code 9659/3. According to the Hematopoietic database, this histology frequently has T-cells. The other description was not an actual histology, but noting that the appearance of the cells was similar to that histology. |

20180013 | Reportability--Brain and CNS: Are tuberous sclerosis cancers found in the brain reportable? See Discussion. |
I have searched ICD-O-3 for a histology listing but could not locate. I also searched the SEER Inquiry database for possible answers, but none were found. The patient underwent a pediatric MRI of the brain of which final impression was: 1) Subependymoma nodules, cortical tubers, and SEGAs are seen bilaterally consistent with tuberous sclerosis. |
SEGA (Subependymal giant cell astrocytoma) is reportable if diagnosed in 2004 or later. Tuberous sclerosis complex (TSC) is not a neoplasm and is not reportable. SEGA is a neoplasm that commonly occurs in TSC patients. Refer to the reportability instructions on pages 5-7 in the SEER manual, https://seer.cancer.gov/manuals/2016/SPCSM_2016_maindoc.pdf |

20180098 | Solid Tumor Rules (2018)/Histology: Please provide further explanation for prioritizing biomarkers in the histology coding rules. See Discussion. |
The 2018 Solid Tumor (ST) Rules General Rules state: For those sites/histologies which have recognized biomarkers, the biomarkers frequently identify the histologic type. Currently there are clinical trials being conducted to determine whether these biomarkers can be used to identify multiple primaries. Follow the Multiple Primary Rules; do not code multiple primaries based on biomarkers. Additionally, Biomarkers is at the top of the priority order to identify histology in several sections (it appears to be excluded from only Colon, Melanoma and Other sections). In the sections that include this rule, there is not much additional information on using biomarkers. Can you please provide further explanation for prioritizing biomarkers in the histology coding rules? For example, will the ST manual be updated when we need to look for specific biomarkers in a diagnosis? |
Instructions for biomarkers will be added to other site rules when applicable. The use of biomarkers to determine a specific histologic type is not yet a standard of care in the majority of cases. |

20180023 | Reportability/Behavior: Is myxoinflammatory fibroblastic sarcoma (MIFS) reportable for 2018? This histology is on the 2018 ICD-O-3 histology update list with a behavior code of /1. See discussion. |
This will be a tough one for registrars to recognize as non-reportable since the terminology contains sarcoma, so we just want to double check. |
Myxoinflammatory fibroblastic sarcoma (MIFS) (C49._), 8811/1, is not reportable for 2018 based on the 2018 ICD-O-3 New Codes, Behaviors, and Terms list. This is a new histology/behavior not previously listed in ICD-O-3. According to the WHO 4th Ed Tumors of Soft Tissue & Bone, this histology has been given a benign (/1) behavior; however, if the pathologist and/or physician state the tumor is malignant or metastatic, report the case and assign behavior code /3. |

20180015 | Histology--Ovary: What is the correct ICD-O-3 histology code for sertoliform endometrioid carcinoma of the ovary? |
Assign 8380/3. Sertoliform endometrioid carcinoma is a variant of endometrioid carcinoma according to the WHO Classification of Tumors of Female Reproductive Organs, 4th edition. There is no specific ICD-O-3 code for this variant. |

|
20180030 | First Course of Treatment/Surgery of Primary Site--Melanoma: How do you code UVB therapy treatment for melanoma? |
Code UVB therapy for melanoma as photodynamic therapy under Surgery of Primary Site for skin. Assign code 11 [Photodynamic therapy (PDT)] if there is no pathology specimen. Assign code 21 [Photodynamic therapy (PDT)] if there is a pathology specimen. Use text fields to document details. |

|
20190004 | Systemic/Surgery Sequence: Does the Systemic/Surgery Sequence field apply to only the first surgery performed (Date of First Surgical Procedure) or does it apply to the most definitive surgery (Date Most Definitive Surgery) as well? See Discussion. |
Example: Bladder primary with transurethral resection of the bladder tumor (TURBT) on 2/17/2017 (Date of First Surgical Proc) followed by a second TURBT on 3/24/2017 (Date Most Definitive Surgery) with mitomycin C instilled on the second, most definitive TURB procedure. There is an edit failure (IFX166) when Systemic/Surgery Sequence is coded 5 (intra-operative systemic) and Systemic Date does not match Date of First Surgical Procedure. How should we capture the intra-operative systemic treatment during the second, most definitive TURB? Is the correct Surgery/Systemic Sequence code 3 (systemic after surgery) for this case because (intra-operative) chemo was technically given after the first surgery? |
Assign code 3 to Systemic/Surgery Sequence and document the intraoperative treatment in the text field. Surgery is defined as a Surgical Procedure to the Primary Site (codes 10-90), Scope of RLN Surgery (codes 1-7), or Surgical Procedure of Other Site (codes 1-5) in the 2018 SEER Manual. In this case, the treatment was after the first surgical procedure. |

20190062 | Solid Tumor Rules (2018)/Histology--Brain: How is histology coded for a left frontal lobe mass when the final diagnosis is malignant neuroglial tumor and the diagnosis comment describes multiple possible histologies? See Discussion. |
Left frontal mass biopsy diagnosis comment states: Given the synaptophysin and patchy CD34 staining of these cells, the possibility of ganglioglioma and pleomorphic xanthoastrocytoma is raised. Astroblastoma and ependymoma were considered given the perivascular pseudorosettes, however GFAP staining is quite limited against these tumors. Reticulin stain shows limited perivascular reticulin staining however. Nevertheless, the necrosis, mitotic activity and elevated mitotic activity would point to a malignant neoplasm. Given the neural and limited GFAP staining, a generic classification of neuroglial is provided. This is the only available information. Further clarification or discussion with the physician or pathologist is not possible. Therefore, is this diagnosis of neuroglial tumor equivalent to that described in SINQ 20091037? |
Code to 8000/3. Use text fields to record the details. The WHO Revised 4th Ed CNS Tumors includes a chapter for "Neuronal and mixed neuronal-glial tumors. This chapter lists 13 histologies in this category. Glioneuronal NOS is not listed. Do not assign 9505 because ambiguous terminology was used AND because of the numerous possible histologies discussed for this diagnosis. |

20190030 | Summary Stage 2018/Extension--Prostate: Can imaging be used to code SEER Summary Stage 2018? MRI shows tumor involved the seminal vesicles and the patient did not have surgery. AJCC does not use imaging to clinically TNM stage a prostate case. |
Note 5 was changed in Version 2.0. Per Note 5 of the 2018 SEER Summary Stage Prostate chapter: Imaging is not used to determine the clinical extension. If a physician incorporates imaging findings into their evaluation (including the clinical T category), do not use this information. This note was changed in Version 2.0 (2021 changes) to be in line with how AJCC stages; therefore, AJCC and Summary Stage agree. |

20190070 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded for a when the pathologist notes the low grade B-cell lymphoma raises the possibilities of extranodal marginal zone lymphoma of mucosa associated tissue (MALT lymphoma) and lymphoplasmacytic lymphoma (LPL)? See Discussion. |
Rule PH28 confirms the more specific histologies are ignored if this is truly a low grade B-cell lymphoma (i.e., non-Hodgkin lymphoma, NOS) since both MALT lymphoma and LPL are more specific types of low grade B-cell lymphomas. This leaves only a diagnosis of low grade B-cell lymphoma with plasmacytic differentiation to consider. SINQ 20130033 states a low grade B-cell lymphoma with plasmacytic differentiation should be coded as 9680/3 (diffuse large B-cell lymphoma (DLBCL)). However, DLBCL is a high grade B-cell lymphoma, not a low grade B-cell lymphoma. If the pathologist classifies this as a non-specific low grade B-cell lymphoma, and clarifies that this may represent a more specific type of low grade B-cell lymphoma (MALT lymphoma or LPL), should the histology be coded to a high-grade lymphoma (DLBCL) or non-Hodgkin lymphoma, NOS? |
Code low grade B-cell lymphoma with plasmacytic differentiation as 9591/3 (Non-Hodgkin lymphoma, NOS). Plasmacytic differentiation is commonly seen with B-cell neoplasms. If further information identifies a more specific histology, the abstract can be updated to reflect the more specific histology. In the latest WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues, 4th ed., there is confirmation that DLBCL is a high grade B-cell neoplasm. We will update the SINQ question. |
