20160010 | Grade--Head & Neck: How should grade be coded for a tonsillar primary (or other solid tumor) with resection pathology final diagnosis of poorly differentiated SCC with histologic grade: G2-3 of 3. See discussion. |
We are seeing multiple head and neck cases with unclear or multiple grade assignments. Another example is alveolar mucosa SCC with histologic grade stated as: Moderately differentiated (G2 of 3). Grade Coding for Solid Tumor instruction 5.b. is not clear regarding this situation. Does a statement of differentiation take priority? Should we disregard the differentiation statement and code using the 3-grade systems? |
Use the three-grade system table in instruction #7.b to code grade for the situations you describe. Use the Grade Coding Instructions in order. Instruction #7.b (three-grade system) comes before instruction #8 (terminology).

20160015 | Multiple primaries--Heme & Lymphoid Neoplasms: Could you please clarify Note 2 found in Rule M10, which is " 'Transformations to' (acute neoplasms) and 'Transformations from' (chronic neoplasms) are defined for each applicable histology in the database." Do the neoplasms being considered have to contain the words 'chronic' and/or 'acute'? |
Hematopoietic neoplasms that transform generally don't have 'chronic' or 'acute' as part of their preferred name. The 'chronic' and 'acute' designations are determined by the usual course of the neoplasm. Chronic neoplasms are generally slow growing while acute neoplasms grow fast and are more widespread. Not all Hematopoietic neoplasms transform. Each neoplasm that has the ability to transform has the transformations listed under the 'Transformations to' and/or 'Transformation from' sections in the Hematopoietic database.
For example, Diffuse large B-cell lymphoma (histology code 9680/3) has no histologies/neoplasms listed under 'transformations to.' This means that this neoplasm does not transform to any other neoplasm. There are multiple histologies/neoplasms listed under 'Transformations from' indicating the neoplasms listed under the Transformations from are the chronic neoplasms, and DLBCL is the acute neoplasm. If DLBCL (9680/3) occurs at the same time, within 21 days, or greater than 21 days of any of the histologies listed under 'Transformations From,' rules M8-M13 apply. If DLBCL (9680/3) occurred at the same time as a neoplasm not listed in the Transformations sections, the acute and chronic rules do not apply. |

20160034 | First course treatment/Immunotherapy--Heme & Lymphoid Neoplasms: Is donor leukocyte infusion for treatment of hematopoietic neoplasms coded as a bone marrow transplant per the Hematopoetic Manual or as immunotherapy per SEER Inquiry System (SINQ) 20110048? See Discussion. |
In the Hematopoetic Manual, page 22, it is states: "The use of donor leukocyte infusions for treatment of hematopoietic neoplasms, specifically leukemias, is increasing. Abstract as bone marrow transplant when a reportable hematopoietic neoplasm is treated with donor leukocyte infusion, even if it is not listed in the treatment section of the Heme db for the specific neoplasm." Question 20110048 in the SEER Inquiry, it is stated "Donor lymphocyte infusion (DLI) is coded as immunotherapy." Donor lymphocyte infusion and donor leukocyte infusions are the same procedure. Please clarify discrepancy as coding is needed for a case treated with donor lymphocytic infusion. |
Code donor lymphocyte infusion as immunotherapy. SINQ 20110048 is correct. The Hematopoietic Manual will be corrected during the next update. |

20160031 | MP/H Rules/Histology--Brain and CNS: What is the code for Rosette-forming glioneural tumor from a pathology report of a brain tumor biopsy for a date of diagnosis in 2015? See Discussion. |
This diagnosis is not listed in the ICD-O-3 though it is listed as code 9509/1 for this specific tumor in the 2007 WHO classification of Tumours of Central Nervous System. (See link: http://link.springer.com/article/10.1007/s00401-007-0243-4/fulltext.html.) |
Assign 9505/1 for Rosette-forming glioneuronal tumor. The new code, 9509/1, has not been implemented in the United States. 9505/1 is to be used until the new code is implemented. See page 7 of the NAACCR Guidelines for ICD-O-D Implementation, effective January 1, 2014, http://www.naaccr.org/LinkClick.aspx?fileticket=u7d3sB71t5w%3d&tabid=126&mid=466. |

20160002 | MP/H Rules/Histology--Breast: Which is the correct histology code to use and which MP/H rule applies in the case of a single lumpectomy specimen that demonstrates two separate tumors with the following histologies. 1) Invasive lobular carcinoma 2) Invasive ductal carcinoma with tubular features See discussion. |
Does ductal carcinoma with tubular features qualify for Breast MP/H Rule H28? Or, is it more appropriate to strictly follow Table 2 (not a type of ductal tumor) and apply Rule H29, thus losing the lobular component? |
Abstract a single primary using Rule M13. Assign 8523/3 using rule H29. The code for invasive ductal carcinoma with tubular features (8523/3) is higher than the code for invasive lobular carcinoma (8520/3). H28 does not apply because 8523/3 is not included as a type of duct carcinoma on Table 2. |

20160067 | MP/H Rules/Histology--Skin: What histology code and MP/H Rule apply to a skin primary with the final diagnosis, ? See Discussion. |
The patient had an upper arm shave biopsy with final diagnosis of basaloid carcinoma with squamous and neuroendocrine differentiation. The pathologist also comments: Further resection was negative for residual malignancy.
Would SINQ 20150033 apply, thus resulting in final histology of carcinoma with neuroendocrine carcinoma (8574/3)? |
Assign 8574/3 according to Other Sites rule H17 for basaloid carcinoma with squamous and neuroendocrine differentiation.
There is no combination code that includes basal cell, squamous, and neuroendocrine. We can combine basal cell with squamous, 8094/3, or carcinoma with neuoendocrine differentiation, 8574/3. Rule H17 directs us to assign the higher code, 8574/3. |

20160036 | Reportability/Histology--Head and Neck: Is mammary analogue secretory carcinoma (MASC) of the left submandibular gland reportable and how is it coded? See Discussion. |
The physician is calling it an indolent tumor, pT3/NX/M0 stage 3 with positive margins. Is the correct code C509, 8502/3? |
Mammary analogue secretory carcinoma (MASC) is reportable. MASC is a recently described tumor that predominantly arises in the parotid gland. In this case, if the primary site is submandibular gland, assign C080. We contacted our expert pathologist and he stated that the best code to use for MASC is 8502/3. Override any edits triggered by the combination of C080 and 8502/3. |

20160055 | Reportability--Bone: Is an "atypical cartilaginous tumor" reportable? See Discussion. |
Patient had a core needle biopsy of the right acetabulum. Final diagnosis on the path report is: Atypical cartilaginous tumor (formerly chondrosarcoma, grade 1).
Is this cell type reportable? If so, is it reportable only because the pathologist recorded clarifying text in parentheses? If the text in the parentheses was not available, is the histology "atypical cartilaginous tumor" reportable? |
Atypical cartilaginous tumor of bone is not reportable. The WHO terminology is "atypical cartilagenous tumor/chondrosarcoma grade I." WHO classifies this entity as low malignant potential (behavior code /1).
Chondrosarcoma grade II or grade III is reportable based on the WHO classification of malignant (behavior code /3). |

20160028 | MP/H/Histology--Sarcoma: How should Ewing Sarcoma/primitive neuroectodermal tumor (PNET) be coded for a 2012 case? See Discussion. |
SEER SINQ 20031051 applies to cases diagnosed before 2007 and advises: Code histology as 9260/3, Ewing sarcoma. Ewing sarcoma is a specific histology on the continuum of primitive neuroectodermal tumors. Code Ewing sarcoma as it is more specific than PNET, NOS.
For tumors diagnosed 2007 or later, refer to the MP/H rules. |
Apply 2007 MP/H rule H6 and assign the numerically higher ICD-O-3 code that reflects PNET (9364/3). According to the WHO Tumors of Soft Tissue and Bone, though Ewing sarcoma ICD-O-3 code is 9260/3, Ewing sarcoma with a higher degree of neuroectodermal differentiation present is classically termed peripheral neuroectodermal tumors (PNET). WHO does not offer guidance how to classify tumors stated to be Ewing sarcoma PNET.
Histology code 9364/3 is assigned for a Ewing/PNET that arises outside of the brain/CNS. Peripheral neuroectodermal tumor (PNET) and peripheral primitive neuroectodermal tumor (PPNET) are Ewing family tumors.
Histology code 9473/3 (PNET, primitive neuroectodermal tumor, central primitive neuroectodermal tumor, or supratentorial PNET) is only used for tumors arising inside the brain/CNS. |
