20200068 | Summary Stage 2018/Extension--Colon: Are colon primaries coded as local or regional (direct extension) on Summary Stage based on invasion into the pericolorectal tissues? For example, is a case with an ascending colon tumor that extends into the pericolorectal tissues, pT3, local or regional by direct extension? |
Code as Localized using the SEER Summary Stage Manual, Colon and Rectum, Note 6. Localized is for subsites that are not peritonealized, including the posterior side of the ascending colon, or when the pathologist does not further describe the "pericolic/perirectal tissues" as either "non-peritonealized pericolic/perirectal tissues" vs "peritonealized pericolic/perirectal tissues" fat and the gross description does not describe the tumor relation to the serosa/peritoneal surface, and it cannot be determined whether the tumor arises in a peritonealized portion of the colon. Refer to the coding instructions in both EOD and Summary Stage for a list of sites that are nonperitonealized or peritonealized. . |

20200031 | Histology/Behavior--Breast: How are histology and behavior coded for a case originally diagnosed as in situ and later an invasive tumor with a different histology is diagnosed but still a single primary using Breast Solid Tumor Rule M10? See Discussion. |
SINQ 20200022 indicates that cases originally diagnosed as in situ do not have a new primary when a new invasive tumor with a different histology is diagnosed within 5 years. Should histology and/or behavior get updated for the in situ breast primary? |
Update the histology and behavior based on the invasive tumor when an invasive tumor is diagnosed within 5 years of an in situ tumor in the same breast. This will be updated in the 2021 revisions of the Breast Solid Tumor Rules. |

20200049 | Summary Stage 2018/EOD 2018--Lymphoma Orbital Adnexa: What is the correct Summary Stage 2018 (SS2018) for the site/histology Orbit, NOS (C696), 9699/3? In SEER*RSA, Extent of Disease (EOD) Primary Tumor references code 7 (Distant), whereas SS2018 assigns code 2 (Regional)? See Discussion. |
We received an edit error in SEER*DMS on the following site/histology (Orbit, NOS (C696)/9699/3) that involved an incorrect staging code being assigned to SS2018. The staging language is identical in AJCC, EOD and SS2018. SEER*RSA notes that SS2018 should be coded distant, but in the SS2018 manual, this language is noted Regional. Staging language is: Orbital adnexal lymphoma AND extraorbital lymphoma extending beyond the orbit to adjacent structures--Bone, Brain, Maxillofacial sinuses |
To clear this edit of the derived Summary Stage (based on EOD) and the manually assigned Summary Stage (based on Summary Stage 2018), assign the manually assigned Summary Stage to 7. For this particular case, EOD Primary Tumor 700 (which is correct based on the information received) derives Distant; however, for Summary Stage 2018, this description is under Code 2 for Regional by direct extension. This is an error. For 2022, Summary Stage for Lymphoma Ocular Adnexa description under Code 2 (Regional by direct extension) will be moved to Distant. No changes will be done to EOD. |

20200069 | Solid Tumor Rules (2018)/Histology--Breast: What histology code is used for an in situ encapsulated papillary carcinoma with an invasive carcinoma, NST? See Discussion. |
In Table 3 (Specific Histologies, NOS/ NST, and Subtypes/Variants), the entry for papillary carcinoma, NOS includes a change in column 3 of the 2018 Breast Solid Tumor Rules that conflicts with the H Rules. It is not accounted for in the change log. No explanation is offered as to why this change was made. This is a major change because encapsulated papillary carcinoma is frequently associated with carcinoma NST, and we have not been collecting these as such. Encapsulated papillary carcinoma (8504) in column 3 now includes an indented entry, with invasive carcinoma, NST/invasive duct carcinoma 8504/3. However, most encapsulated papillary carcinomas are in situ or there is no definitive statement of invasive encapsulated papillary carcinoma, so when in situ and invasive tumors are present, we are instructed to code the invasive histology (which would be the invasive carcinoma (NST), 8500/3). How are registrars to arrive at the correct histology without a new H rule or a clarification regarding this update being documented in the change log? Does the same change/addition apply to solid papillary carcinoma? These are often also associated with carcinoma, NST. Again, without an explanation regarding the change mentioned above, it is difficult to understand why the change was made. This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
In situ encapsulated papillary arising in or with invasive carcinoma, NST (a single tumor) is a single invasive histology. Use rule H14 and code the histology per Table 3. A note as been added to the 2023 breast rule H8 instructing when there is a single tumor with histology of in situ encapsulated papillary with invasive carcinoma or solid papillary carcinoma with invasove, continue through the rules. See H14 and code the appropriate histology per Table 3. Histologic types are becoming more complex and often have both in situ and invasive components but have a single code to identify them. |

20200085 | Solid Tumor Rules (2018)/Histology--Head and Neck: What is the histology of paraganglioma, NOS arising outside of the adrenal gland (for example, in the bladder) for cases diagnosed 1/1/2021 and later? See Discussion. |
Should histology be coded as paraganglioma, NOS (8680/3) or as extra-adrenal paraganglioma, NOS (8693/3) for a diagnosis of paraganglioma in the bladder? Does the pathologist have to specifically diagnose the tumor as extra-adrenal paraganglioma, NOS to use histology code 8693/3? Or, does any diagnosis of paraganglioma (NOS) arising outside of the adrenal gland, carotid body, middle ear, or aortic body (the specified sites for other types of paragangliomas) qualify as an extra-adrenal paraganglioma, NOS? The ICD-O-3.2 Implementation Guidelines (Tables 6 and 7) provide an associated site of C755 for histology 8680/3 (paraganglioma, NOS), but no associated site code is provided for histology 8693/3 (extra-adrenal paraganglioma, NOS). If the preferred site for paraganglioma, NOS is the paraganglia, would a paraganglioma in the bladder be an extra-adrenal paraganglioma? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
Code the histology stated by the pathologist: paraganglioma, NOS 8680/3. |

20200058 | Surgery of Primary Site/Surgery Codes, NOS--Pancreas: What exactly is an extended pancreatoduodenectomy? Must the entire pancreas be resected in order to use code 70? What minimal requirements must be met to use code 70? How should a Whipple with cholecystectomy, partial omentectomy, common hepatic excision, portal vein resection, and lymphadenectomy be coded? |
According to our research, a pancreaticoduodenectomy (PD) includes an en bloc resection of the pancreatic head, the common bile duct, the gallbladder, the duodenum, the upper jejunum, the distal portion of the stomach and the adjacent lymph nodes. The extended PD procedure includes extended lymphadenectomy, extended organ resection, and extended vascular resection and reconstruction. Code 70 could be assigned without the entire pancreas being resected. A Whipple procedure removes the head of the pancreas, duodenum, stomach and gallbladder and part the common bile duct. The portal vein resection is probably part of the common bile duct excision. If the omentectomy was performed for treatment of this primary, record it in "Surgical Procedure of Other Site." Record the lymphadenectomy in the lymph node data items. |

20200007 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is simultaneously diagnosed with systemic mastocytosis and chronic myelomonocytic leukemia (CMML-0) on a single bone marrow biopsy? See Discussion. |
The Hematopoietic and Lymphoid Neoplasms Database (Heme DB) definition for systemic mastocytosis with an associated hematological neoplasm (SM-AHN, 9741/3) states SM-AHN is a variant of systemic mastocytosis that arises with a myeloid disease of non-mast cell lineage (e.g., MDS, MPN, etc.) and that, However, SINQ 20130172 conflicts with the Heme DB stating the systemic mastocytosis and the associated hematological neoplasm are a single primary coded to a single histology (9741/3) per Rule M2. |
Abstract a single primary when the diagnosis is systemic mastocytosis with an associated clonal hematogoical non-mast cell lineage disease (SM-AHNMD) (9741/3). However, if the patient has a previous history of myelodysplastic syndrome, myeloproliferative neoplasm, myelodysplastic/myeloproliferative neoplasm or acute leukemia, abstract the SM-AHNMD as a second primary as stated in the Heme DB. SINQ 20130172 represents a single primary as there is no mention of a prior history of myelodysplastic syndrome, myeloproliferative neoplasm, myelodysplastic/myeloproliferative neoplasm or acute leukemia. |

20200027 | Reportability--Ambiguous Terminology: Should either of the terms, strongly characteristic of or most certainly, be used to accession a case as reportable when they are used to describe a malignancy and no other information is available? See Discussion. |
SINQ 20130140 indicates a histologic diagnosis that is characteristic of a specified malignancy is reportable because this is equivalent to the term, diagnostic of. Does the same logic apply to a clinical diagnosis that is strongly characteristic of a malignancy on imaging? SINQ 20180104 indicates the term, almost certainly, is not a reportable ambiguous term. If a radiologist notes a mass was most certainly malignant, is this adequate to accession this as reportable? Is a clinically certain diagnosis equivalent to diagnostic of? Or are the modifiers almost and most irrelevant because the terms certainly and certain are not on the ambiguous terminology list? |
Look for more information. What is the plan for each of these patients? Consult with the physician and search for further information to assist with the decision. If no further information can be obtained, accession both of these cases based on the imaging reports. If more information becomes available later, review and revise as applicable. |

20200064 | Primary site--Heme &Lymphoid Neoplasms: What is the primary site of two extraosseous plasmacytomas, with positive pathology of right orbit and left lung. The patient's bone marrow biopsy, flow, and peripheral blood smear were negative. Is this coded as 9732/3, multiple myeloma (Primary Site and Histology Rule PH2) with the primary site as C809 (PH27)? Or is the primary site C421 since code 9732 says primary site is always C421, though bone marrow came back as negative? |
Assign the primary site to C421 since that is the only allowable primary site for plasma cell myeloma, even though the bone marrow was negative. According to the revised criteria from the WHO Blue Book for Hematopoietic and Lymphoid Neoplasms (2017), the presence of multiple plasmacytomas is plasma cell myeloma (9732/3). |

20200050 | Surgery of Primary Site/Multiple primaries--Breast: Should the Surgery of Primary Site for the 2020 diagnosis be coded 51 (Modified radical mastectomy without removal of uninvolved contralateral breast) when a partial mastectomy and axillary lymph node dissection are performed for a 2011 right breast primary and a subsequent 2020 right breast primary is treated with a total mastectomy only? See Discussion. |
The patient underwent a partial mastectomy and sentinel lymph node biopsy, followed by an axillary lymph node dissection for the first right breast primary in 2011. The separate 2020 right breast primary was treated with a total mastectomy and removal of one involved axillary lymph node. The operative report only refers to this as a non-sentinel lymph node, with no mention of other axillary findings. Cumulatively, this patient has undergone a modified radical mastectomy since there were likely no remaining axillary lymph nodes. If the Surgery of Primary Site data item is cumulative, does the order of surgeries matter? It is unclear whether this question should be directed to SINQ (for coding in a SEER registry) or to CAnswer Forum because both have addressed similar surgery related questions in the past and and there is no guidance regarding this specific situation. |
Yes, assign surgery of primary site code 51 for the 2020 diagnosis in this case. Code the cumulative effect of all surgeries to the primary site. This means that for the 2020 primary, code the cumulative effect of the surgery done in 2011 plus the surgery performed in 2020. Use text fields on both abstracts to record the details. |
