20210064 | Solid Tumor Rules (2018/2021)/Multiple primaries--Ovary: How many primaries should be reported when patient has right fallopian tube high-grade serous carcinoma and bilateral serous tubal intraepithelial carcinoma (STIC)? See Discussion. |
Patient is diagnosed March 2021, with malignant pleural effusion, clinical impression supports either endometrial or tubo-ovarian primary and neoadjuvant chemotherapy is given. Subsequent total abdominal hysterectomy/bilateral salpingo-oophorectomy (TAH/BSO) in July, shows high-grade serous carcinoma involving the right fallopian tube and bilateral ovaries, as well as bilateral STIC. Summary Stage lists tumor site as right fallopian tube, with the serous tubal intraepithelial carcinoma (STIC) noted under “additional findings.” Should the contralateral (left-sided) STIC be accessioned as an additional primary, per MP/H Rule M8, the since fallopian tubes are listed in Table 1 as Paired Organs with Laterality? |
Abstract as multiple primaries per rule M8. There are bilateral fallopian tube primaries. It sounds like the "primary" tumor was identified in the right fallopian tube with bilateral spread of disease. Incidental STIC was also identifed in the left fallopian tube. Do not record the STIC as another primary. |

20210045 | Update to Current Manual/Neoadjuvant Treatment: What codes should be used for Neoadjuvant Therapy--Clinical Response and Neoadjuvant Therapy--Treatment Effect when the neoadjuvant therapy is still in progress at the time the case is initially abstracted as with rapid reporting. There is no code for neoadjuvant therapy still in progress and code 9 generates an edit for Neoadjuvant Therapy--Clinical Response. |
Assign code 8 for Neoadjuvant Therapy--Clinical Response and assign a code 9 for Neoadjuvant Therapy--Treatment Effect when the treatment is still in progress. Revise these codes after the treatment has been completed. We will update the manual to include these instructions. |

20210008 | Solid Tumor Rules (2018, 2021)/Histology--Melanoma: In what situation will Rule H6 be used to code the histology to lentigo maligna melanoma? See Discussion. |
Rule H6 states: Code 8742/3 (Lentigo maligna melanoma) when the diagnosis is lentigo maligna melanoma with no other histologic types. However, if the diagnosis was strictly lentigo maligna or lentigo maligna melanoma, the first rule that applies is Rule H1 because lentigo maligna melanoma is a single, specific histologic type and Rule H1 states, Code the histology when only one histologic type is identified. Following the current rules, one would never arrive at Rule H6. Should the H Rules be reordered? Or should an example of when one would use Rule H6 be added to clarify when to use this rule? |
Solid Tumor rule H6 is the same as MP/H rule H8. We found registrars have problems understanding reportable terminology and the corresponding ICD-O-3 histology code for lentigo maligna melanoma. It is included in H6 to capture cases where the registrar may not stop at H1. We will add another note to H1 instructing users to continue through the rules if the diagnosis is lentigo maligna melanoma. |

20210018 | Reportability/Histology--Head & Neck: Is carcinoma cuniculatum of the hard palate diagnosed in 2017 reportable? Was this rare variant of squamous cell carcinoma (SCC) missed in Casefinding? If reportable, what is the histology code? |
Carcinoma cuniculatum of the hard palate is reportable. Code to SCC, NOS (8070/3). Use text fields to record the details. While WHO recognizes carcinoma cuniculatum to be a new variant of oral cancer, it has not proposed a new ICD-O code for this neoplasm. |

20210062 | Histology/Reportability--Heme and Lymphoid Neoplasms: Is a case that is compatible with low grade myelodysplastic syndrome with multilineage dysplasia (MDS-MLD) reportable, and if so, is the histology plasma cell myeloma or myelodysplastic syndrome (MDS)? See Discussion. |
HL-7 e-path report, Final Diagnosis High normocellular marrow with maturing trilineage hematopoiesis, multilineage dyspoiesis, compatible with MDS-MLD and involvement by plasma cell neoplasm/myeloma, IgA kappa positive, approximately 20-25% of total cellularity present. See comment. Comments Correlation with other relevant laboratory (amount and type of serum and urine paraprotein levels, renal function tests, serum calcium level, and anemia) and radiologic (lytic bone lesions) findings is recommended for complete interpretation. Dyspoiesis of all lineages is seen and the findings are compatible with low grade myelodysplastic syndrome (MDS-MLD), assuming that other possible causes are excluded. Correlation with cytogenetic and molecular studies is recommended for complete characterization |
This case is reportable. Assign MDS, NOS (9989/3) based on the information provided for this case. “Compatible with” can be used for reportability; however, it cannot be used for assigning histology. There is no confirmed diagnosis of plasma cell myeloma/neoplasm; the comment specifically addresses the need for further evaluation of this case. |

20210063 | Solid Tumor Rules (2018/2021)/Multiple primaries--Ovary: How many primaries should be reported and for which primary site(s) when pathologist identifies bilateral ovarian high-grade serous carcinoma with involvement of the left fallopian tube (also showing serous tubal intraepithelial carcinoma (STIC))? See Discussion. |
Patient is diagnosed July 2021 with high-grade serous carcinoma on ascites cytology. Tumor debulking total abdominal hysterectomy/bilateral salpingo-oophorectomy in August shows high-grade serous carcinoma involving the right ovary (capsule intact, right fallopian tube is negative), left ovary (capsule ruptured), and fallopian tube. Pathologist has chosen tumor site to be bilateral ovaries in the staging summary, with the left fallopian tube listed as “other tissue/organ involvement” along with uterus, peritoneum, and omentum. Additional findings in staging summary includes serous tubal intraepithelial carcinoma (STIC). Our interpretation of SINQ 20210025 is that any case with both ovarian and tubal involvement would be coded as a fallopian tube primary if STIC is present, even when the pathologist is clearly calling the case ovarian. If this is correct, then the previous SINQ 20120093 may need to be updated with a date restriction reference since it would be in disagreement with this instruction. If our interpretation is incorrect, then the STIC would be an additional primary per MP/H Rule M11. |
Bilateral ovarian tumors are a single primary per M7. Abstract the STIC as a second primary. SINQ 20210025 is intented to address situations with confliciting information about the primary site. The answers remain unchanged in 2012009 and 20210025. |

20210002 | Multiple Primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a patient diagnosed with therapy-related myelodysplastic syndrome (t-MDS) (9920/3) in 2015 followed by a 2020 diagnosis of myelodysplastic syndrome, NOS (MDS, NOS) (9989/3)? See Discussion. |
Patient has a history of B-cell lymphoma with multimodality treatment in 2002. Lab work in 2015 showed multilineage dysplasia leading to a diagnosis of therapy-related myelodysplastic syndrome. Patient presents in 2020 for a bone marrow biopsy now showing low-grade MDS. The MDS appears to have the same multilineage dysplasia previously identified. MDS, NOS is not listed in the Heme DB as a possible transformation of t-MDS, nor is it listed as a Same Primary for t-MDS. Likewise, t-MDS is not listed as a more specific myelodysplastic syndrome, a transformation of MDS NOS, or a Same Primary as MDS, NOS. The first M rule that applies to this case is M15, and the Multiple Primaries Calculator indicates that the MDS, NOS should be a new primary. |
Abstract separate primaries using Rule M15 of the Hematopoietic and Lymphoid Neoplasms (Heme) Manual. The Heme Database states: Excluded from this category are progression of myeloproliferative neoplasms (MPNs) and evolution of primary MDS or primary MDS/MPN to acute myeloid leukemia (AML); in each of these latter cases evolution to AML is part of the natural history of the primary disease and it may be impossible to distinguish natural progression from therapy-related changes. There is no indication of transformation. |

20210067 | First Course Treatment/Neoadjuvant Treatment: How is Neoadjuvant Therapy--Clinical Response (NAACCR #1633) coded if a physician documents excellent response to treatment and nothing further? |
Clarify the statement of "excellent" with the managing physician if possible. If no further information can be obtained, assign code 8 in Neoadjuvant Therapy–Clinical Response and document the details in text fields. |

20210056 | 2018 Solid Tumor Rules/Multiple Primaries--Breast: How many primaries should be reported when a left breast simple mastectomy identifies focal Paget disease of the nipple and 12 axillary nodes positive for metastatic lobular carcinoma (no primary lobular breast tumor identified)? |
Abstract two primaries, one lobular carcinoma (8520/3) and another one Paget disease of the breast (8540/3) using the 2018 Breast Solid Tumor Rules, Rule M9: Abstract multiple primaries when the diagnosis is Paget disease with underlying tumor which is NOT duct. Example: Paget disease of the nipple with underlying lobular carcinoma are multiple primaries. Additionally, Table 2, Histology Combination Codes, Note 2 states: Lobular carcinoma and Paget are separate primaries (see Lobular carcinoma and any histology in Table 3 with exception of duct carcinoma/carcinoma NST/DCIS (and subtypes/variants) 8500 and Paget disease, in situ and invasive). While not identified in the pathology of the mastectomy, the lobular carcinoma is likely underlying as it was identified in the axillary lymph nodes. The 2021 SEER Manual states: If the only pathologic specimen is from a metastatic site, code the appropriate histology code and the malignant behavior code (/3). The primary site and its metastatic site(s) have the same histology. |

20210038 | Update to current manual/First course treatment--Neoadjuvant treatment: How are the 2021 neoadjuvant therapy fields coded when neoadjuvant therapy and surgery were part of first course plans but treatment was never completed. See Discussion. |
Example: Breast case where first course treatment plan is neoadjuvant therapy and surgery after. The patient was hospitalized during neoadjuvant therapy, elected hospice, and later died, so the neoadjuvant therapy was never completed, surgery not done. How are the 2021 neoadjuvant therapy fields coded in this situation as neoadjuvant therapy and surgery were part of first course plans. I coded neoadjuvant therapy to 2 - started but not completed, but there are no codes to properly explain the clinical response and therapy treatment effect as the patient did not complete neoadjuvant therapy. Should I use code 9 for clinical response and treatment effect or should this be left blank for this particular case? |
Assign code 8 for Neoadjuvant Therapy--Clinical Response in this case. We will update the SEER manual to allow code 2, in addition to code 1, in Neoadjuvant therapy when Clinical Response is coded 8. We will also add instructions covering a case such as this one. Assign code 7 for Neoadjuvant Therapy--Treatment Effect and use text fields to record the details. We will add instructions to the manual for this scenario. |
