20130100 | Multiple primaries/Primary site--Heme & Lymphoid Neoplasms: How many primaries are there and how should I code the primary site(s)? See discussion. |
Patient had a hemicolectomy and a salpingo-oophorectomy and was found to have diffuse large B cell lymphoma in the colon (10 cm cecal mass), 3/16 regional lymph nodes involved with lymphoma. Fallopian tube showed involvement with diffuse large B Cell lymphoma.
Multiple primaries - Colon and fallopian tube?
One primary - Colon? Stage IV, or lymphoma from an unknown primary? Note: There were no other lymph nodes involved. |
Use Rule M2. Abstract as a single primary when there is a single histology.
When you have questions about how to code the primary site, start with the abstractor notes. If the answer isn't found there go to Module 7 (a specific module to help code primary site for lymphomas).
The abstractor notes for DLBCL in this case do not provide information you can use for this case. Go to Module 7 in the PH rules.
Use Rule PH25 Code the primary site to the organ when lymphoma is present in an organ and that organ’s regional lymph nodes. Code the primary site to colon (organ and regional lymph nodes involved). The fallopian tube is secondary involvement. As is common with lymphomas, there can be more than one organ involved. You can differentiate the primary site from the secondary site(s) because of the large colon mass with regional lymph node involvement. |

20130216 | Primary site--Heme & Lymphoid Neoplasms: Need help determining primary site for Diffuse Large B-Cell Lymphoma 9680/3 confirmed pathologically in right ovary and soft tissue left adnexa. No lymph nodes examined pathologically. Patient treated outside and no access to notes. See discussion. |
CT A/P massively enlarged uterus with no distention between the vagina, cervix or proximal to mid uterus identified. Highly concerning for malignancy though distinct etiology not clear. Ovarian not favored though not excluded given lack of clearly defined fat planes between uterus and either ovary. Extensive bilateral iliac chain and periaortic/pericaval lymphadenopathy.
Trying to work through Module 7 in the Hem DB. According to the ovary site, regional lymph nodes include the iliac and the para-aortic lymph nodes. This makes me think I should use Rule PH35 (organ and regional nodes). However, using Appendix C in the Hem DB, the iliac lymph nodes are part of the pelvic C775 while the para-aortic (periaortic) are intra-abdominal C772. This makes me wonder if I should go with rule PH36 present in organ and nodes that are not regional. |
Use Rule PH25 and code primary site to C569.
First determine if the iliac and para-aortic lymph nodes are regional for Ovary. Use AJCC TNM or Collaborative Stage. Per AJCC 7th edition, regional lymph nodes for ovary include iliac and para-aortic (pg. 419). Therefore, this case involves an organ and its regional lymph nodes. Use appendix C to determine how to code a lymph node primary. It should not be used to determine whether lymph nodes are regional for a specific organ. |

20240054 | EOD 2018/Primary Tumor--Breast: We are having difficulty deciding when we can or cannot use physician-assigned TNM staging to code EOD data items if the medical record or hospital abstract documentation is unclear. As a central registry, we are unable to query physicians for clarification. Please advise what is a “discrepancy” in the EOD General Instructions to “Use the medical record documentation to assign EOD when there is a discrepancy between the T, N, M information and the documentation in the medical record.” See Discussion. |
We know that physician TNM staging is not always accurate, and we also know that doctors sometimes use information in assigning their TNM which may not be available to registrars. Is it a discrepancy when the documentation in the chart is unclear or not definitive, yet the physician assigns a TNM that seems to incorporate that documentation? Or is a discrepancy an obvious conflict between chart documentation and the doctor’s staging – such as a mis-assignment of TNM category that doesn’t at all match with clear and complete medical record documentation, or the physician’s use of criteria that should be excluded from the TNM assignment per AJCC guidelines? A real case example is a patient with breast carcinoma, imaging states 12 cm tumor with thickening of dermis, and thickening of morphologically suspicious internal mammary and level 1-2 axillary lymph nodes. Medical oncologist states locally advanced breast cancer with extensive changes involving skin thickening associated with the mass, at least stage IIIC based on imaging and exam findings, cT4 N3b. Only axillary nodes were sampled and found to be positive. Post-neoadjuvant therapy resection showed only focal DCIS. Per EOD guidelines, would the oncologist’s staging be a discrepancy with the chart documentation and therefore ignored, with EOD-Primary Tumor coded 200 for skin thickening, and EOD-Lymph Nodes 200 for involvement of axillary nodes only? Or would the doctor’s TNM be a clarification/confirmation of documentation terms that we otherwise would not code, with EOD-PT coded 400 for extensive skin involvement and EOD-LNs 600 for internal mammary + axillary nodes? |
Use all information available in the medical record. EOD is a combination of the most precise clinical and pathological documentation of the extent of disease as instructed in the EOD 2018 General Instructions, Extent of Disease section. EOD 2018 General Instructions, General Coding Instructions section advises to use the medical record documentation to assign EOD when there is a discrepancy between the T, N, M information and the documentation in the medical record. When there is doubt that the documentation in the medical record is complete, code the EOD corresponding to the physician staging. A discrepancy can exist within the medical record when the information in the chart is unclear, incomplete, or conflicting, for example, the TNM staging from pathology differs from the medical oncologist’s TNM staging. In the scenario provided, use the medical oncologist stage information that takes into account imaging and exam findings. Based on the stage cT4 N3b, assign EOD Primary Tumor: 400 Extensive skin involvement WITHOUT a stated diagnosis of inflammatory carcinoma WITH or WITHOUT dermal lymphatic filtration EOD Regional Nodes: 600 Internal mammary node(s), ipsilateral, clinically apparent (On imaging or clinical exam) WITH axillary (level I, II, or III) lymph node(s), ipsilateral including infraclavicular |

20140066 | First course treatment: When a patient has a Haplo bone marrow transplant, is this coded as an allogenic bone marrow transplant since part of his marrow was used in addition to a donor? |
Use code 12 in the Hematologic Transplant & Endocrine Procedures data field. Per the NCI, this procedure is an allogeneic transplant.
Rather than wiping out a patient’s immune system before transplanting donor bone marrow, doctors administer just enough chemotherapy to suppress the immune system, which keeps patients from rejecting the donated marrow without harming their organs. The procedure requires just a half-match, meaning that a patient’s parents or children could be suitable donors. AKA: Half-match transplants. |

20200011 | Race: How should race information from linkages be incorporated into the coding of Race? See Discussion. |
Race information is provided in the Centers for Medicare and Medicaid Services (CMS) linkage results. Oftentimes it matches what is coded in the database, but other times it does not. In situations where the CMS (or other) linkage provides a race value that differs from the coded Patient set, are we to ignore the CMS stated race given the SEER Manual instructions indicating self-reported race has priority or should we add the different Race values from linkages as an additional race (ex. Race 02)? |
Use self-reported race as the priority when information on race is available. Use the associated text field to document why a particular race code was chosen when there are discrepancies in race information. Generally, race information is used from linkages when race data is missing or unknown, or to enhance data. We will add clarification on linkages in the next SEER Manual update. |

20110027 | MP/H Rules/Multiple primaries/Histology--Thyroid: How many primaries and what histology(ies) are coded when a patient is diagnosed with a single papillary carcinoma in the left thyroid lobe and multiple foci of papillary microcarcinoma in the right thyroid lobe? See Discussion. | Is the term papillary microcarcinoma being used to describe the size of the foci only, or are the right thyroid lobe lesions a different histologic type? Does rule M6 apply (single primary)? Or does rule M11 apply (multiple primaries)?
Case summary: Left thyroid with 2.2 cm papillary carcinoma and right thyroid with "multiple microscopic foci of papillary carcinoma (papillary microcarcinoma) ranging from less than 1 mm to 2 mm in greatest dimension." |
Use the Multiple Primary and Histology Coding Rules Manual for cases diagnosed 2007 or later to determine the number of primaries. This is a single primary.
For thyroid cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult. The histology is the same in both lobes of the thyroid.
The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules manual. For a thyroid primary, use the Other Sites MP rules under one of the three formats (i.e., flowchart, matrix or text) to determine the number of primaries because the thyroid does not have site specific rules.
Start with the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within the module from Rule M3 to Rule M18. You stop at the first rule that applies to the case you are processing.
. This patient has multiple papillary carcinomas of the thyroid diagnosed simultaneously; no other rule applies, so this is a single primary. Abstract a single primary for this patient.
Determine the histology code. For a thyroid, use one of the three formats (i.e., flowchart, matrix or text) under the Other Sites Histo rules to determine histology because thyroid primaries do not have site specific rules.
Start with the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY module, Rule H18. The rules are intended to be reviewed in consecutive order within the module from Rule H18 to Rule H31. You stop at the first rule that applies to the case you are processing.
. Code papillary carcinoma of the thyroid to papillary adenocarcinoma, NOS [8260]. |

20110028 | MP/H Rules/Histology--Thyroid: How many primaries and what histology(ies) are coded when the pathology report shows a, 1.9 cm Hurthle cell carcinoma, probable follicular variant of papillary carcinoma, with Hurthle cell features and a 2 mm focus of follicular variant, papillary carcinoma? See Discussion. | Right lobectomy pathology report final diagnosis states: 1.9 cm Hurthle cell carcinoma (see comment). Comment: histologic diagnosis Hurthle cell carcinoma, probable follicular variant of papillary carcinoma with Hurthle cell features. Subsequent left lobectomy one week later showed a 2 mm microscopic focus of follicular variant of papillary carcinoma, encapsulated.
None of the rules seems to fit this scenario. The number of primaries reported for this case depends on the histology coded for each tumor. Does Rule M6 (Follicular and papillary tumors in the thyroid within 60 days of diagnosis are a single primary.) or M17 (Tumors with ICD-O-3 histology codes that are at the first (xxx), second (xxx) or third (xxx) number are multiple primaries.) apply? Does the case represent a single primary because both are papillary/follicular tumors or two primaries because one is Hurthle cell carcinoma, and one is papillary/follicular carcinoma (different histology at second digit)?
To code the histology for the larger tumor in the right lobe, which rule do we apply? Rule H11 (single histology of Hurthle cell carcinoma [8290] per path final diagnosis), H15 (tumor has both follicular and papillary carcinoma [8340], per path comment), or H17 (numerically higher code for 8340 because there is both Hurthle cell and papillary/follicular carcinoma)? |
Use the Multiple Primary and Histology Coding Rules Manual for cases diagnosed 2007 or later to determine the number of primaries. This is a single primary.
The Hurthle cell carcinoma is a synonym for follicular carcinoma according to the WHO. See page 67 of the 2004 WHO Classification of Tumours of Endocrine Organs. The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules manual. For a thyroid primary, use the Other Sites MP rules under one of the three formats (i.e., flowchart, matrix or text) to determine the number of primaries because the thyroid does not have site specific rules.
Start with the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within the module from Rule M3 to Rule M18. You stop at the first rule that applies to the case you are processing.
. Follicular and papillary tumors in the thyroid within 60 days of diagnosis are a single primary. The patient has a tumor in each lobe of the thyroid with the same histology. Abstract a single primary for this patient.
Determine the histology code. For a thyroid, use one of the three formats (i.e., flowchart, matrix or text) under the Other Sites Histo rules to determine histology because thyroid primaries do not have site specific rules.
Start with the SINGLE TUMOR: INVASIVE ONLY module, Rule H8. The rules are intended to be reviewed in consecutive order within the module from Rule H8 to Rule H18. You stop at the first rule that applies to the case you are processing.
. Code follicular and papillary carcinoma of the thyroid to papillary carcinoma, follicular variant (8340). Use the comment to code the histology for the right lobectomy. "Probable" is an acceptable ambiguous term to use for coding histology. (See the Ambiguous Terms Used to Code Histology section of the General Instructions in the MP/H manual.) |

20110068 | MP/H Rules/Multiple primaries--Bladder: Which multiple primary rule is used to determine the number of primaries to accession when a patient has a papillary transitional cell carcinoma of the bladder diagnosed in 2009 followed by a high grade invasive urothelial carcinoma with neuroendocrine features per immunohistochemistry diagnosed in 2010? See Discussion. | A patient has papillary transitional cell carcinoma of the bladder in March of 2009. In June of 2010 the patient has another TURBT that demonstrates a flat in situ and invasive high grade urothelial carcinoma. The path addendum indicates, "Genzyme IHC show results consistent with high grade invasive urothelial carcinoma with neuroendocrine features." Two months later a liver biopsy shows poorly differentiated malignant tumor. The path addendum indicates, "Genzyme IHC results show metastatic poorly differentiated carcinoma with neuroendocrine features, favor bladder primary."
Is the latter a second bladder primary with histology code 8246/3 [neuroendocrine carcinoma]?
NOTE: Neuroendocrine is not listed as an urothelial tumor in Table 1 of MP/H Rules. |
Use the Multiple Primary and Histology Coding Rules Manual for cases diagnosed 2007 or later to determine the number of primaries. This is a single primary. The 2010 diagnosis is urothelial carcinoma. The presence of "neuroendocrine features" does not change the histologic category.
The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules manual. Once in the manual, locate the Urinary MP rules under one of the three formats (i.e., flowchart, matrix or text). The rules are intended to be reviewed in consecutive order within the module. You stop at the first rule that applies to the case you are processing.
Start at the MULTIPLE TUMORS module start at rule M3.
. Bladder tumors with any combination of transitional cell carcinoma and papillary transitional carcinoma are a single primary. |

20210001 | SEER*RSA/Required data items--Melanoma: The site-specific data item, Ulceration, states it is required by "All" in SEER*RSA but in the NAACCR Data Dictionary table it states is it required by SEER, Commission on Cancer (CoC), and Canadian Cancer Registry (CCCR), not the National Program of Cancer Registries (NPCR). Does the definition of "All" in SEER*RSA not include NPCR? Also, please explain the difference between Required by: "All" and "Required by CCCR/Canada, COC, NPCR, SEER" (all listed out). |
Use the NAACCR Data Dictionary Required Status Table or refer to standard setter requirements. Do not use SEER*RSA to determine which data items are required to be collected or transmitted. Though "All" in SEER*RSA generally refers to the standard setters including CoC, NPCR, CCCR, and SEER, some items in SEER*RSA need updating; this is planned for 2022. |

20180104 | Reportability--Ambiguous terminology: Are the following terms reportable: almost certainly and until proven otherwise? See Discussion. |
Example 1: Physician states patient has an almost certain melanoma. Due to the patient's age, there is no plan to for any treatment or further workup. Almost certain is not listed as a reportable phrase, so typically we would not accession this case. Example 2: Imaging states a diagnosis of renal cell carcinoma until proven otherwise. No additional workup is available at this facility. This terminology is also not seen on the ambiguous reportable terminology list but we are seeing it more often and wanted confirmation. |
Use the ambiguous terminology list as a last resort. Consult with the physician and search for further information to assist with the decision. If no further information can be obtained, use the ambiguous terms list to decide; in this case, the terms are not on the list and these examples would not be reportable. |
