20180082 | Summary Stage Manual 2018 "Lymphoma: SEER Summary Stage 2000 states: For lymphomas, any mention of lymph nodes is indicative of involvement and is used to determine the number and location of lymph node chains involved (see lymphoma scheme). This statement is not in SEER Summary Stage 2018. Does that mean we follow rules #4-7, pages 14-15, under Code 3: Regional Lymph Nodes only, for every site, including lymphoma? |
The following statement "Any mention of the terms including fixed, matted, mass in the hilum, mediastinum, retroperitoneum, and/or mesentery, palpable, enlarged, shotty, lymphadenopathy are all regarded as involvement for lymphomas when determining appropriate code," is included in EOD Primary Tumor and is applicable to Summary Stage 2018. The statement will be added as note 4 to the Lymphoma Summary Stage chapter. This will be included in the 2019 update (estimated release January 2019). |

20180093 | 2018 Solid Tumor Rules/Multiple primaries--Lung: What is the histology and number of primaries for a lung case diagnosed in 2018 with adenocarcinoma with acinar predominant pattern on biopsy, and subsequent lobectomy showing adenocarcinoma with solid growth pattern and separate adenocarcinoma with lepidic predominant pattern? Should this be coded as one primary with an adenocarcinoma, NOS (8140/3) histology since we cannot use pattern or predominant, based on the histologic type listed in the synoptic report, and the fact it states synchronous primary tumors in the same lobe. See Discussion. |
02/18 RUL biopsy: Moderatley differentiated adenocacarcinoma with acinar predominant pattern 04/18 RUL lobectomy: 6.5cm poorly differentiated adenocarcinoma with solid growth pattern and 1.1 cm separate adenocarcinoma with lepidic predominant pattern Synoptic report: Procedure: Lobectomy Specimen Laterality: Right Tumor Tumor Site: Upper lobe Histologic Type: Invasive adenocarcinoma, solid predominant Tumor Size: 6.5 Centimeters (cm) Tumor Focality: Synchronous primary tumors in same lobe Lymph Nodes Number of Lymph Nodes Involved: 0 Number of Lymph Nodes Examined: 12 Nodal Stations Examined: 4R: Lower paratracheal; 8R: Para-esophageal (below carina); 10R: Hilar; 7: Subcarinal Pathologic Stage Classification (pTNM, AJCC 8th Edition) Primary Tumor (pT): pT3 Regional Lymph Nodes (pN): pN0 |
This is a single primary per Lung rule M7. First determine the histology for each tumor. Both tumors are coded 8140/3 because the histologies are a PATTERN. Reference: Coding Multiple Histologies (precedes histology rules) Instruction 2 says do not code pattern . If the word pattern was not in the diagnosis, you would code the specific histology. |

20180026 | Solid Tumor Rules (2018)--Breast: How many primaries are accessioned when a prophylactic mastectomy reveals a final diagnosis of invasive tubular carcinoma, but the College of American Pathologists (CAP) Protocol includes ductal carcinoma in situ (DCIS) sized separately and it is not clear if these are different tumors? See Discussion. |
The patient was incidentally diagnosed with cancer on a prophylactic mastectomy, so there are no positive imaging findings to correlate the number of tumors/masses. The final diagnosis was invasive tubular carcinoma, and referred to the CAP Protocol. The CAP notes: However, it does not specify whether the single contiguous focus also includes the in situ component. The CAP goes on to note DCIS was present: The gross description does not provide any indication of either a single or multiple tumors/masses/lesions, though it was referred to as "Lesion 1" in the gross description with no indication of other lesions. The format of the CAP Protocol frequently does not specify whether the DCIS is a separate measured tumor, or if it is a component of the invasive tumor. This makes it difficult to determine whether the DCIS should be a separate primary when the invasive tumor is not also a type of ductal carcinoma. Per both the 2007 MP/H and 2018 Solid Tumor Rules, an invasive tubular carcinoma and a ductal carcinoma in situ would be multiple primaries if they were multiple tumors. Should we default to Rule M1: Abstract a single primary when it is not possible to determine if there is a single or multiple tumors? Or should we assume these are separate tumors because they were both sized, the focality only described a single invasive tumor, and the tumors are not both ductal carcinomas? |
Accession a single primary using Solid Tumor Rule M3. Based on the information provided, this was described as "Lesion 1' with no other lesions noted in the gross description. If the DCIS was a separate tumor, this would have been noted by the pathologist. Reminder, the breast CAP protocol is a checklist for pathologists to note their findings while reviewing the slides and/or specimen. The findings and notes should be consolidated into a final/synoptic report. |

20180107 | Solid Tumor Rules (2018)/Histology--Lung: If the pathology states non-small cell carcinoma of the lung (NSCLC), consistent with squamous cell carcinoma, is the code non-small cell carcinoma according to the Solid Tumor Rules? The Medical Oncologist states that the tumor is a squamous cell carcinoma. In these instances would you code the squamous cell carcinoma since you have a definite physician statement? |
Code the histology to SCC 8070/3. Based on registrar feedback on the NSCLC rule, we added a rule that specifically addresses when ambiguous terminology can be used to code histology other than NSCLC. The lung rules were update 10/12/2018 so please make sure you are using the currently posted rules. The new rule is: Rule H3-Code the specific histology when the diagnosis is non-small cell lung carcinoma (NSCLC) consistent with (or any other ambiguous term) a specific carcinoma (such as adenocarcinoma, squamous cell carcinoma, etc.) when: * Clinically confirmed by a physician (attending, pathologist, oncologist, pulmonologist, etc.) * Patient is treated for the histology described by an ambiguous term * The case is accessioned (added to your database) based on ambiguous terminology and no other histology information is available/documented Example 1: The pathology diagnosis is NSCLC consistent with adenocarcinoma. The oncology consult says the patient has adenocarcinoma of the right lung. This is clinical confirmation of the diagnosis, code adenocarcinoma. Your case meets the criteria in bullet 1. |

20180006 | MP/H Rules/Histology--Breast: Should encapsulated papillary carcinoma of the breast with a separate focus of ductal carcinoma in situ be coded as 8050/2 (papillary carcinoma) and staged as in situ? See Discussion. |
Pathology--Right breast, lumpectomy with needle localization: Encapsulated papillary carcinoma of the breast. A separate focus of ductal carcinoma in situ is present. Sentinel lymph node, right breast, biopsy: One lymph node, negative for malignancy. No metastatic carcinoma is seen on slides stained with immunostain for cytokeratin (AE1/AE3). Specimen laterality: Right. Tumor size: 1.2 cm. Histologic type: Encapsulated papillary carcinoma. Nuclear grade: Grade 1 (low). Mitotic rate: Score 1. Ductal carcinoma in situ (DCIS): DCIS is present. Estimated size (extent) of DCIS: 3 mm. Architectural patterns: Cribriform and papillary. Nuclear grade: grade 1 (low). Necrosis: Not identified. Margins: Margins uninvolved by encapsulated papillary carcinoma. Distance from closest margin: 8 mm, superior Margins uninvolved by DCIS. Distance from closest margin: 11 mm, superior Lymph nodes: Total number of lymph nodes examined (sentinel and nonsentinel): 1. Number of sentinel lymph nodes examined: 1. Number of lymph nodes with tumor cells: 0. Pathologic staging: Primary tumor: See comment. Regional lymph nodes: pN0(i-). Comment: In the WHO Classification of Tumours of the Breast (2012), it is stated that "there is no universal agreement on how to stage encapsulated papillary carcinomas. In the absence of conventional invasive carcinoma, the consensus of the WHO Working Group was that such lesions should be staged and managed as Tis disease." |
For cases diagnosed prior to 2018 Code as encapsulated papillary carcinoma, 8504/3; this is a synonym for intracystic carcinoma (WHO Classification of Tumors of the Breast). Stage this case as invasive. |

20180054 | Solid Tumor Rules (2018)/Histology--Bladder: Under the Terms that are Not Equivalent or Equal section (Urinary Equivalent Terms and Definitions) it indicates noninvasive is not equivalent to papillary urothelial carcinoma and one should code the histology documented by the pathologist. However, many pathologists use Ta as both the description of the stage and the histology. Should this note be amended? See Discussion. |
The note in the Urinary Terms and Definition states, Both Ta and Tis tumors are technically noninvasive. Code the histology specified by the pathologist. While it is true that both Ta and Tis are technically noninvasive, the AJCC defines Ta specifically for, A pathologist's use of Ta does indicate the noninvasive carcinoma did arise from a papillary tumor. However, not all pathologists use terminology that, following the Urinary Solid Tumor Histology Coding Rules, will result in a histology coded to 8130, despite an AJCC-defined Ta (noninvasive papillary carcinoma) tumor having been diagnosed because the tumor projected from the wall on a stalk. In our region a number of pathologists provide the following types of diagnosis. Histologic type: Noninvasive. Histologic grade (WHO/ISUP 2016): High-grade. Tumor configuration: Papillary. The pathologist and/or physician may then stage this as Ta. How is the histology coded for these cases if the H Rules do not allow one to code the papillary and noninvasive Ta disease as not equivalent to noninvasive papillary carcinoma? Flat (in situ) urothelial carcinoma has an increased risk of invasive disease compared to the noninvasive papillary urothelial carcinomas. Will there be inconsistencies or a resulting impact to analysis of truly flat/in situ urothelial carcinoma vs. papillary urothelial carcinomas if the papillary tumors are not being coded as such? |
Per the April 2019 update: Noninvasive; papillary urothelial carcinoma; flat urothelial carcinoma Note: Noninvasive is not equivalent to either papillary urothelial or flat urothelial carcinoma. Both Ta and Tis tumors are technically noninvasive. Code the histology specified by the pathologist. |

20190051 | Update to current manual/Solid Tumor Rules (2018)/Histology--Lung: What is the histology code and what M Rule applies when there are multiple specific subtypes identified using various equivalent lung terms but only one is stated to be predominant? See Discussion. |
Example: Lung resection final diagnosis is Lung adenocarcinoma, see Summary Cancer Data, and the Summary Cancer Data (CAP Synoptic Report) states Histologic type: Invasive adenocarcinoma, solid predominant. Other Subtypes Present: 20% acinar and <5% micropapillary components. Instruction 1B and Note 1 for Coding Multiple Histologies (Lung Histology Rules) indicates type, subtype, component, and predominantly are all terms that may be used to code the most specific histology. In this case, the multiple specific histologies were documented using all of those terms. Note 2 for instruction 1B states predominantly describes the greatest amount of tumor and when it is used for the listed subtypes of adenocarcinoma, that subtype should be coded. However, Note 2 does not indicate that the other subtypes are ignored when one is identified to be predominant and the others are identified as subtype or component only. |
Code to invasive adenocarcinoma, solid predominant (8230/3), based on the example, using Lung Solid Tumor Rules Coding Multiple Histologies instruction #1 that says to code the specific histology where the most specific histology may be described as component, majority/majority of, or predominantly, in this case, 75%. Apply Rule M2 as this appears to be a single tumor with multiple histologies based on the information provided. The rules will be updated to add a new H rule and to reviseTable 2 when two or more histologies described as predominant are present. |

20190047 | Reportability/Liver: If on imaging, there is no statement of the Liver Imaging Reporting and Data System (LI-RADS) score but there is reference that a lesion is in the Organ Procurement and Transplantation Network (OPTN) 5 category, is hepatocellular carcinoma (HCC) reportable based on the OPTN 5 classification? See Discussion. |
SINQ 20160008 discusses the reportabilty and diagnosis date for liver primaries where imaging references the LI-RADS category as LR-5 or LR-5V. The 2018 SEER Coding and Staging Manual, Appendix E Reportable Example #16, demonstrates this concept. According to the LI-RADS categories a value of 5 is "definitely HCC" and is concordant with OPTN 5. Often we see only the OPTN categorization. |
Report HCC based on the OPTN class of 5. OPTN class 5 indicates that a nodule meets radiologic criteria for HCC. Be sure to document in text fields. |

20190010 | Reportability/Histology--Bladder: Is papillary urothelial neoplasm of low malignant potential (PUNLMP) (8130/1) reportable when also referred to as papillary transitional cell carcinoma, grade 1, no invasion (8130/2) previously? See Discussion. |
The pathology report reads: Urinary bladder, tumor over right ureteral orifice, biopsy: Urinary bladder mucosa (urothelium) and submucosa (lamina propria), with papillary urothelial neoplasm of low malignant potential (previously known as papillary transitional cell carcinoma, grade 1 of 3), no invasion identified. |
This case is not reportable. PUNLMP (8130/1) is the diagnosis stated by the pathologist for this case and PUNLMP is not reportable. The information in parentheses is informational in this case and does not change the pathologist's diagnosis. According to WHO Classification of Tumors of the Urinary System and Male Genital Organs, 4th edition, there is variation of architectural and cytological features between PUNLMP and papillary urothelial carcinoma, low grade, reflecting grading changes from an older classification system. |

20190048 | Reportability/Histology--Skin: Is malignant hidroacanthoma simplex of the scalp reportable? If so, what is the histology? |
Malignant hidroacanthoma simplex of the scalp is reportable. Malignant hidroacanthoma simplex is a synonym for porocarcinoma, 8409/3. |
