20120039 | Primary site--Heme & Lymphoid Neoplasms: What primary site and heme rule applies when a PET scan shows bilateral renal masses, hypermetabolic liver lesions and retroperitoneal lymphadenopathy, a right kidney biopsy was positive for diffuse large B-cell lymphoma, and the bone marrow biopsy was negative? See Discussion. |
Patient has a history of chronic lymphocytic leukemia (CLL). February 2011 abdomen/pelvis x-ray showed development of bilateral renal masses. April 2011 PET scan showed intense areas of hypermetabolic activity corresponding to known bilateral renal masses, new hypermetabolic liver lesions, as well as left upper retroperitoneal lymphadenopathy. All findings are worrisome for malignancy. March 2011 right kidney mass biopsy was positive for diffuse large B-cell lymphoma (DLBCL). Bone marrow biopsy was negative for lymphoma. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Per Rule PH25, code the primary site of the diffuse large B-cell lymphoma to C649 (kidneys) and laterality to 4 (bilateral). Per PH25, code the primary site to the organ when a lymphoma is present in an and that . This patient had involvement of an organ (bilateral kidneys) as well as regional lymph nodes for that organ. The retroperitoneal lymph nodes are regional for the kidney. The diffuse large B-cell lymphoma is an acute transformation of the chronic lymphocytic leukemia. Because the DLBCL occurred more than 21 days after the CLL, it is a new primary per Rule M10. SEER*Educate provides training on how to use the Heme Manual and DB.

20190064 | Multiple Primaries--Heme & Lymphoid Neoplasms: Patient is diagnosed with myelodysplastic syndrome (MDS) with an early/evolving acute myeloid leukemia (AML) thought to be treatment related. Does rule M11 apply since there are two biopsies within 21 days, and therefore, two primaries, or one primary (9920/3)? See Discussion. |
Patient has a history of breast cancer and diffuse large B-cell lymphoma (DLBCL), both treated with chemotherapy and radiation. On 6/26/19, bone marrow biopsy: MDS with excess blasts-2 (18% dysplastic blasts) in a normocellular marrow (overall 40% cellularity) with trilineage dysplasia. Comment: least myelodysplastic syndrome with excess blasts-2. However, an early/evolving AML cannot be completely excluded. The findings likely represent therapy-related myeloid neoplasm. MD note on 7/15/19: Diagnosis: MDS, high grade borderline AML with complex karyotype secondary disease. Patient has high grade MDS which is bordering on AML transformation with 20% blasts by IHC and areas higher than this. This is likely secondary to the treatment she has received for her other cancers particularly pelvic radiation for her DLBCL. Given her very high IPSS score, it is likely she will eventually develop AML. No treatment given. On 7/15/19, bone marrow biopsy: Persistent acute leukemia in a marrow with trilineage dyspoiesis and 23% blasts. |
Code as one primary (9920/3). This case does not fit the rules very well, since it is a treatment-related neoplasm and involves a transformation of MDS to AML during the clinical workup. Per the abstractor notes for 9920/3, code 9920/3 when the physician comments that the neoplasm is treatment related. This can be for the MDS or the AML. Use text fields to document that it was first referred to as MDS and then transformed to AML. If you followed the rules strictly and coded this as two primaries (the MDS and AML), you would lose the information that this was treatment related, which is more important. |

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. |

20220003 | Reportability/Histology--Anus: Are 2021 diagnoses of anal intraepithelial neoplasia (AIN) II or AIN II-III reportable in patients with a known history of AIN II or AIN II-III diagnosed prior to 2021? See Discussion. |
Patient has a history of AIN I/low-grade squamous intraepithelial lesion (LSIL) dating back to at least 2015, was diagnosed with AIN II-III in 12/2019, and then diagnosed again with AIN II-III in 08/2021. There is no indication of treatment or a disease-free interval for this patient. SINQ 20210015, while not an exact match to this case, implies there is no clear disease-free interval for these AIN diagnoses, so it is the same non-reportable neoplasm diagnosed prior to reportability (12/2019). However, there was a diagnosis of a reportable neoplasm in 2021, so it also seems possible this would be accessioned as a reportable tumor based on a diagnosis of reportable tumor diagnosis in 2021. With the reportability changes for these intraepithelial neoplasia II/II-III tumors, these situations will arise more frequently. |
Report AIN II and AIN II-III cases when initially diagnosed in 2021 or later. Do not report retrospective cases; that is, cases with diagnoses prior to 2021 with continuation of AIN II or AIN II-III extending into the reportable period. |

20160075 | MP/H Rules/Histology--Breast: What histology code(s) and MP/H rule applies for a breast resection final diagnosis of "undifferentiated sarcoma associated with a malignant phyllodes tumor and a tumor size of approximately 7 x 6.5 x 4 cm"? (The tumor is primarily sarcoma, with the phyllodes tumor measuring 2.8 cm)? See Discussion. |
Patient has a diagnosis of undifferentiated sarcoma with an associated malignant phyllodes tumor in a single mass. Should this be abstracted as two primaries, one for an undifferentiated sarcoma and the other for a malignant phyllodes tumor? Which MP/H rule applies? |
Abstract a single primary. Based on the information provided, this is a single tumor, and therefore a single primary, Rule M3. Code the histology to malignant phyllodes tumor. According to our expert pathologist consultant, "The presence of a phyllodes tumor component identifies the whole thing as such. Stromal overgrowth/sarcoma is the usual identifier of malignancy in a phyllodes tumor. (If there were no phyllodes component we would be left with undifferentiated sarcoma, but that is not the case here. The diagnosis of malignancy in phyllodes tumor may be difficult/problematic when there is no overt stromal/sarcoma overgrowth as in this case.) As an aside, the behaviors of pure sarcoma and a phyllodes tumor such as we have here are similar, but we would lose the primary diagnosis if we just called this sarcoma." |

20220010 | EOD 2018/Heme & Lymphoid Neoplasms--Myeloid Sarcoma: How is Extent of Disease (EOD) Primary Tumor coded for a myeloid sarcoma with multifocal skin involvement? See Discussion. |
Patient has a diagnosis of myeloid sarcoma presenting as multiple erythematous papules and nodules on back, chest, right arm & shoulder. Oncologist did not mention any evidence or suspicion of an associated AML diagnosis. HemeRetic schema EOD Primary Tumor Note 1 states that myeloid sarcoma can be coded as localized (code 100) or systemic (code 700). It is not clear what would qualify as systemic disease for myeloid sarcoma. |
Assign code 100, localized, using the 2018 EOD Primary Tumor, HemeRetic schema, for the myeloid sarcoma with skin involvement since only the skin is involved. Use code 700, distant or disseminated, when multiple organs are involved. |

20230067 | First Course Treatment/Scope of Regional Lymph Node Surgery--Breast: How is Scope of Regional Lymph Node Surgery coded when initially there is a sentinel lymph node biopsy (SLNBx) and an intramammary node removed followed a month later by an axillary dissection for a right breast primary? See Discussion. |
Patient has a diagnosis of invasive carcinoma of the right breast from a core biopsy on 04/2023. Subsequent bilateral mastectomy and sentinel node biopsy proves one positive sentinel node and one negative intramammary node. One month later there is a completion axillary node dissection with 15 nodes negative for malignancy. Per previous SINQ 20190074, the initial mastectomy and sentinel node excision with intramammary node removal should be coded as Scope of Regional Lymph Node Surgery 6. It is unclear how the resulting axillary dissection should be recorded in Scope of Regional Lymph Node Surgery. There is no code for sentinel node biopsy and 3, 4, or 5 at same time (code 6) PLUS an additional subsequent axillary dissection. Please provide coding instructions for Sentinel Lymph Nodes Positive, Sentinel Lymph Nodes Examined, and Scope of Regional Lymph Node Surgery in this scenario. |
Scope of Regional Lymph Node Surgery: Assign code 7, Sentinel node biopsy and code 3, 4, or 5 at different times. In this case, the SLNBx (code 2) preceded the regional node dissection (code 5: 4 or more regional lymph nodes removed), i.e., procedures performed in separate surgical events. Sentinel Lymph Nodes Examined: Assign code 98, Sentinel lymph nodes were biopsied, but the number is unknown. In this case, only the results were provided. Sentinel Lymph Nodes Positive: Assign code 01, Sentinel nodes are positive (code exact number of nodes positive). In this case, there was one positive sentinel node. |

20130160 | Histology--Heme & Lymphoid Neoplasms: Should the histology be coded to a therapy-related myeloid neoplasm when the physician states the diagnosis of acute myeloid leukemia is secondary to treatment with Imuran? See Discussion. | Patient has a diagnosis of AML for which the physician recommends a bone marrow transplant. The physician indicated the diagnosis is actually a secondary AML due to treatment with Imuran for polymyalgia rheumatica. The physician also stated this is a high risk type of AML. Imuran is not a chemotherapy agent per SEER*Rx. Can the histology be coded as 9920/3 (e.g., Therapy-related acute myeloid leukemia, NOS) when the patient has not been treated with chemotherapy for a reportable disease? The physician is a bone marrow transplant expert who states the AML is therapy-related disease. Bone marrow disease is a listed as a risk for treatment with Imuran. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code this histology to 9920/3 [therapy-related myeloid neoplasm] when the physician states the acute myeloid leukemia is therapy-related.
Therapy-related AML can result from any systemic therapy for benign or malignant diseases. In this case, AML resulted from immune system-suppressing therapy with Imuran for a benign disease, polymyalgia rheumatica. The drugs that induced the AML do not have to be listed in the SEER*Rx database.

20230080 | Solid Tumor Rules/Histology--Brain and CNS: What is the histology code for low grade glioma? See Discussion. |
Patient has a 3 cm tumor in the temporal lobe of the brain. This was noted on MRI 12/2022. The radiologist states this is a low-grade glioma and recommends following with routine scans. No pathology or resection performed or planned. Patient has been followed with imaging every six months with stable disease. Low grade glioma is not currently listed in ICD-O-3.2 or the current Solid Tumor Rules. What histology should be assigned to the case? |
Assign 9380/1 for low grade glioma diagnosed 1/1/2018 forward and for low grade glioma diagnosed prior to 1/1/2018 assign code 8000/1 on the advice of our expert neuropathologists. The site/type combination of C71 _ and 9380/1 will flag histology/site/behavior edits which should be overridden. Low grade glioma is an umbrella term or non-specific diagnosis, primarily seen on radiologic reports such as CT scans and MRIs. Often, the patient is actively followed with scans and surgical intervention delayed or not recommended. WHO Classification of Central Nervous System Tumors, 5th edition, does not recognize this term and indicates that tissue diagnosis (including genetic testing) is needed to provide a specific diagnosis. Since biopsy of these “neoplasms” is not routinely done, a definitive diagnosis is not available. Literature searches yielded conflicting information with some stating low grade gliomas are malignant with an indolent clinical course while others felt they were benign. Until such time as WHO proposes a code for this neoplasm, our expert neuropathologists recommend coding glioma, NOS with borderline behavior 9380/1. |

20210046 | Reportability--Skin: Is dermatofibrosarcoma protuberans (DFSP) with fibrosarcomatous transformation synonymous with dermatofibrosarcoma protuberans, fibrosarcomatous, and therefore reportable for diagnosis year 2021 and forward? See Discussion. |
Patient has a 2021 skin excision showing an atypical spindle cell neoplasm, most consistent with dermatofibrosarcoma protuberans (DFSP) with fibrosarcomatous transformation. Per the ICD-O-3.2 Coding Table, DFSP, NOS has a behavior code of /1, and DFSP, fibrosarcomatous has a behavior code of /3. There is no code listed for DFSP with fibrosarcomatous transformation. Transformation is not included as a term that can/cannot be used for the Other Sites Schema, but this type of DFSP is often described as DFSP with fibrosarcomatous transformation. How do we code DFSP when transformation is used to describe fibrosarcomatous? |
Report DFSP with fibrosarcomatous transformation as it is synonymous with fibrosarcomatous DFSP (8832/3). According to the WHO Classification of Skin Tumors, 4th edition, fibrosarcomatous DFSP is a variant of DFSP and that fibrosarcomatous transformation is seen in approximately 10% of DFSP cases. It is characterized by an often abrupt transition of DFSP. |
