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. |

20190086 | EOD 2018/Primary tumor--Melanoma: The code and level translations in the Note 4 of Extent of Disease (EOD) Primary Tumor for Melanoma Skin seem incorrect. Please advise. * Code 000: In situ * Code 100: Level I (should be level II) (< 0.75 mm Breslow's Depth) * Code 200: Level II (should be level III) (0.76 mm to 1.50 mm Breslow's Depth) * Code 300: Level III (should be level IV) (> 1.50 mm Breslow's Depth) |
Please see the corrected levels below for the note. Note 4: If a Breslow's depth is given in the pathology report and there is no other indication of involvement, the following guidelines may be used (Note: If a physician documents a different Clark's Level than provided by these guidelines, go with the physician's Clark Level) Code 000: Level I (In situ) Code 100: Level II (< 0.75 mm Breslow's Depth) Code 200: Level III (0.76 mm to 1.50 mm Breslow's Depth) Code 300: Level IV (> 1.50 mm Breslow's Depth) Thank you for bringing this to our attention. |

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. |

20190018 | Histology--Thyroid: Should any mention of encapsulated be included in the histology coding (8343/3 vs. 8260/3) for papillary thyroid carcinoma cases? See Discussion. |
Example: Left thyroid lobectomy with final diagnosis When the only mention of encapsulation is included in the tumor characteristics of the College of American Pathologists (CAP) summary, not the pathologist's choice of histologic type, what is the preferred histology? |
Assign 8343/3 for encapsulated variant of papillary thyroid carcinoma. If the pathology report is not available, use the histologic type in addition to other information in the CAP Protocol. |

20190037 | Solid Tumor Rules/Multiple Primaries--Breast: How many primaries should be abstracted for simultaneously diagnosed non-contiguous invasive duct carcinoma and mucinous carcinoma? Does rule M12 apply since the two histologies are on different rows of Table 3 of the Breast Solid Tumor Rules? See Discussion. |
Core biopsy of left breast at 2:00: Invasive ductal carcinoma, Nottingham score 6/9. Core biopsy of left breast at 4:00: Invasive mucinous carcinoma (variant of ductal carcinoma), Nottingham score 5/9. Post neo-adjuvant mastectomy: Main (largest tumor): Invasive ductal carcinoma, upper outer quadrant grade 2. Secondary tumor: mucinous carcinoma, grade 1 at 4:00. |
Abstract multiple primaries when separate, non-contiguous tumors are on different rows in Table 3 of the Breast Solid Tumor Rules. Use Rule M14 as each row in the table reflects a distinctly different histology, in this case, invasive ductal carcinoma (8500) and mucinous carcinoma (8480). |

20190089 | Solid Tumor Rules (2018)/Histology--Lung: Rule H3 of the Solid Tumor Rules was added to capture non-small cell carcinoma modified by ambiguous terminology when the physician confirms the ambiguous term as the histologic diagnosis, also included in Coding Histology instruction 3.B. If differentiation and features are not included in the histology term, does instruction 2 takes precedence? See Discussion. |
For example, pathologic diagnosis is non-small cell carcinoma with squamous features. The medical oncologist describes this as squamous cell carcinoma and begins treatment regimen. As I interpret the rules, we would use code 8046, non-small cell carcinoma, because of instruction 2 and the fact that features is not included in the list of ambiguous terminology. |
Code 8046 using Coding Instruction 2 that says to: Code the histology described as differentiation or features/features of ONLY when there is a specific ICD-O code for the "NOS with ____ features" or "NOS with ____ differentiation." Note: Do not code differentiation or features when there is no specific ICD-O code. In the example, no ambiguous terminology is used. If ambiguous terminology is used indicating a more specific term, you would code to the specific histology. |

20190040 | Reportability--Heme & Lymphoid Neoplasms: Is peripheral blood with a diagnosis of monoclonal B-cell lymphocytosis (MBL) with chronic lymphocytic leukemia (CLL) phenotype reportable for any year? See Discussion. |
SINQ 20180050 and 20130041 appear to have conflicting answers regarding the reportability of MBL with CLL (immuno)phenotype. While the question content of SINQ 20180050 does not reference the CLL phenotype, it is included in the Discussion as part of the oncologist's assessment. The answer does not address the clinical diagnosis of MBL with CLL-phenotype and simply states that monoclonal B-cell lymphocytosis is not reportable. SINQ 20130041 does include the CLL phenotype information in the primary question and it is expanded on in the discussion as present in peripheral blood. Based on that information, the answer is that it should be reportable and coded as CLL (9823/3). |
The description in the question is for 9823/1 per WHO blue book 2016. This description and code are not reportable. We will review the other SINQ questions and revise if necessary. |

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. |

20190094 | Reportability/Heme & Lymphoid Neoplasms--Skin: Is elephantiasis nostras verrucosa (ENV) reportable as a lymphoma? See Discussion. |
The autopsy report indicated a diagnosis of: Skin: Hyperkeratosis and pseudoepitheliomatous hyperplasia as well as reactive angioendotheliomatosis indicating Elephantiasis Nostras Verrucosa. |
Elephantiasis nostras verrucosa (ENV) is not reportable. ENV is a rare form of chronic lymphedema caused by any number of conditions including neoplasms, trauma, radiation treatment, congestive heart failure, obesity, hypothyroidism, chronic venous stasis, and parasitic infection. |

20190108 | Primary site--Breast: how is subsite coded for a breast cancer when it is described as central portion between 1-3:00 or central portion at 12:00? |
See the SEER coding guidelines for breast, https://seer.cancer.gov/manuals/2018/AppendixC/Coding_Guidelines_Breast_2018.pdf Generally, codes C502 - C505 are preferred over C501. C501 would be preferred over C508. Apply these general guidelines when there is no other way to determine the subsite using the available medical documentation. Table 1, Primary Site codes, in the breast solid tumor rules also provide helpful information for coding site. |
