20210074 | Update to Current Manual/Neoadjuvant Therapy--Pancreas: How are the neoadjuvant items coded for a patient who has unresectable pancreatic cancer and starts chemotherapy but will be evaluated after X cycles to see if patient may become a surgical candidate? |
Assign the neoadjuvant therapy data items as if the patient had neoadjuvant therapy. Neoadjuvant Therapy data item would be coded either code 1 or 2 depending on whether the chemotherapy was completed or not. In this case, they are a surgical candidate by having the chemotherapy with the plan from the beginning to evaluate the chemotherapy after X cycles to see if surgery can be performed. After the patient is evaluated, update the abstract as needed. |

20210031 | Reportability--Brain and CNS: Are lipomas of the spinal column reportable as a benign tumor of the central nervous system (CNS)? This is seen occassionally at our pediatric facility. |
Spinal cord tumors (including lipomas) are reportable when they arise in the spinal dura or nerve root. The tumor must be of the spinal cord itself or within the spinal cord dura. Spinal cord tumors are reportable when they arise in the intradural space. A reportable intradural tumor can be either intramedullary or extramedullary. Extramedullary intradural spinal tumors are reportable. A spinal tumor originating in the extradural space is not reportable. If it is outside the dura, it is not reportable because it would be outside the CNS. They are not reportable when they arise in the peripheral nerves. |

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. |

20210039 | Multiple primaries/Heme & Lymphoid Neoplasms--Lymphoma: Is a 2021 right tongue base biopsy showing diffuse large B-cell lymphoma (DLBCL) (9680/3) a new primary following a prior history of hairy cell leukemia-variant (HCL-v) (9591/3) in 2011? See discussion. |
Patient was diagnosed with low-grade non-Hodgkin lymphoma in 2011, later classified as hairy cell leukemia-variant. Right cervical node biopsy in 2020 proved HCL-v and a subsequent 2021 right tongue base biopsy showed DLBCL. The tongue base biopsy path includes the comment, patient has history of HCL-v, but the morphology and flow cytology features are different from the patient's previous right cervical node biopsy. This DLBCL likely represents a second de novo lymphoma, but cannot exclude an unusual transformation of the prior HCL-v. Per Heme Rule M7, abstract a single primary when a more specific histology is diagnosed after an NOS if the Heme DB confirms the same primary. The histology code for HCL-v, 9591/3 is a non-specific code, but it seems like a specific histology. The Heme Calculator does say 9591 and 9680 are the same primary, but we are unsure if that is correct for this case of HCL-v followed by DLBCL. |
Abstract two primaries. This is a transformation from a chronic disease (the Hairy Cell Variant) to an acute disease (DLBCL). Although this rare situation is not clearly covered in the Hematopoietic rules, the fact that this was originally a Hairy Cell Leukemia variant means that the DLBCL is a new primary. |

20210022 | Solid Tumor Rules (2018/2021)/Multiple primaries--Prostate: Is basal cell carcinoma with focal squamous differentiation and a small focus of infiltrating prostatic adenocarcinoma one or two primaries and if one, is the histology 8147/3? See Discussion. |
Scenario: Patient had a transurethral resection of the prostate on 8-29-19, positive for basal cell carcinoma with focal squamous differentiation involving approximately 50% of tissue (determined not to be mets by consult). On 11-14-19, the patient had a prostatectomy positive for residual basal cell carcinoma and a small focus of infiltrating prostatic adenocarcinoma. According to AJCC, 8th edition, page 724, basal cell carcinoma of the prostate is 8147/3 and we ignored the small focus of adenocarcinoma. The above scenario was reported as two primaries (8090/3 and 8140/3), but we are thinking it is one. |
Abstract a single primary and code as 8147/3 using Rule M18 and Rule H17 of the 2018 Other Sites Solid Tumor Rules. This is based on the findings of basal cell carcinoma of the prostate (8147/3) and adenocarcinoma (8140/3). We consulted with the Subject Matter Expert who advises that basal cell carcinoma and basal cell adenocarcinoma can be used interchangeably. This updates previous consultation regarding this histology. The Other Sites rules will be updated for 2022 and include this information in the prostate histology table. |

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. |

20210078 | Solid Tumor Rules (2018/2021)/Multiple Primaries--Skin Cancer: How many primaries are assigned for sebaceous carcinomas using the Solid Tumor/Multiple Primaries/Histology Rules? Does this scenario represent eight separate primaries? See Discussion. |
Details 4/15/2018: Right abdominal wall mass excision: infiltrating sebaceous carcinoma. Noted to have a history of Muir-Torre/Lynch syndrome. 1/21/2019: Two left upper back mass excisions and two lower back (laterality not specified) mass excisions: infiltrating sebaceous carcinomas 8/7/2019: Excision of multiple sebaceous carcinomas from the right posterior back, left posterior thigh, left anterior abdominal wall, left anterior thigh, right scrotum, right lower abdominal fold, all positive for sebaceous carcinoma on pathology report 9/30/2020: Right gluteal mass, left gluteal mass, back (NOS) excisions: sebaceous carcinomas. 10/14/2020: Right back excision: sebaceous carcinoma. Op note: History of Lynch syndrome with multiple sebaceous carcinomas, recurrent back mass, site of prior mass resection. 10/18/2021: Right thigh excision: sebaceous carcinoma Proposed primaries using MP/H Other Sites Rules #1: 4/15/2018: C445-1 #2: 1/21/2019: C445-2, separate from #1 per M8, same as 1/21/19 C445-9 per M18 #3: 8/7/2019: C445-1, separate from #1 per M10, separate from #2 per M8 #4: 8/7/2019: C447-2, separate from #1 & #3 per M8, separate from #2 per M12 #5: 8/7/2019: C632, separate from #1 per M10, separate from #2-#4 per M11 #6: 9/30/2020: C445-2, separate from #1 & #3 per M8, separate from #2, #4 & #5 per M10 #7: 9/30/2020: C445-1, separate from #2, #4 & #6 per M8, separate from #1, #3 & #5 per M10; I do not think the back, NOS (C445-9) is a new primary per M18. #8: 10/18/2021: C447-1, separate from #2, #4 & #6 per M8, separate from #1, #3, #5 & #7 per M10 |
Assign the number of primaries following the Other Sites Solid Tumor Rules. Based on sites, laterality and or timing there are 8 primaries. This is similar to SINQ 20061112 that advised to follow the Multiple Primaries/Histology rules for sebaceous carcinoma. According to the WHO Classification of Skin Tumors, 5th edition, there is a 30-40% risk of local tumor recurrence, and 20-25% risk of distant metastasis. In only one instance did a physician refer this as a recurrence in the available notes. |

20210073 | Solid Tumor Rules (2018/2021)/Multiple Primaries--Corpus Uteri: How many primaries should be reported when a hysterectomy identifies primary endometrial carcinosarcoma (8980/3) and the endometrium has a background of endometrioid intraepithelial neoplasia (EIN) (8380/2)? A tumor size is provided for the carcinosarcoma, but not the background EIN. |
Patient was diagnosed with carcinosarcoma of Mullerian origin on omental/pelvic biopsies in March 2021. First course treatment was neoadjuvant chemotherapy followed by July 2021 resection showing residual primary endometrial carcinosarcoma with cervical stromal invasion and involvement of bilateral tubes/ovaries, omentum, and mesenteric nodule. Additional findings included endometrium with background endometroid intraepithelial neoplasia (EIN). |
Abstract this case as a single primary and code histology as carcinosarcoma (8980/3). The carcinosarcoma is intermixed with the EIN making this a single primary coded to the invasive histology. EIN is a precursor of endometrial carcinoma in the WHO Classification of Female Genital Tumors, 5th edition. Carcinosarcoma of the uterus is described in the literature as an aggressive variant of endometrial carcinoma characterized by unusual histologic features including discrete malignant epithelial and mesenchymal components (carcinoma and sarcoma). |

20210004 | Solid Tumor Rules (2018)/Histology--Colon: What is the histology for a 2020 pathology report final diagnosis showing invasive adenocarcinoma, poorly differentiated with signet ring cell features and signet-ring cell carcinoma in the synoptic report? See Discussion. |
Since the synoptic report and final diagnosis are equal in priority, and the Solid Tumor Rules tell us to code the more specific histology, would this be coded to signet ring cell adenocarcinoma, 8490/3, even though the pathologist used features in the final diagnosis? There is no histology adenocarcinoma with signet ring cell features on the CAP Protocol, so the pathologist may check off the next closest histology " signet ring cell carcinoma " which would not be truly representative of the actual histology. Final Diagnosis: Proximal colon, segmental resection: Invasive adenocarcinoma, poorly differentiated, with signet ring cell features. Synoptic Report A: Colon and Rectum - Resection Specimen Procedure: Right hemicolectomy, Tumor Site: Right (ascending) colon, Histologic Type: Signet-ring cell carcinoma, Histologic Grade: G3: Poorly differentiated. |
Code histology to 8490/3 per H6. The December 2020 Solid Tumor Update includes addition of the following instructions to the "Priority Order for Using Documentation to Code Histology" section. Which document to use when there is conflicting information between the final diagnosis, synoptic report, or CAP protocol: When there are discrepancies between the final diagnosis and synoptic report, use the document that provides the more specific histology. This will likely be found in the synoptic report. The CAP Protocol should be used only when a final diagnosis or synoptic report are not available. Definitions for CAP Protocol, final diagnosis, and synoptic report can be found in the Definitions section. |

20210037 | Reportability/Date of diagnosis--Thyroid: Is category Thyroid imaging reporting and data system (TI-RADS) 4 (4a/4b) or TI-RADS 5 on imaging diagnostic of thyroid cancer, and if so, can we use the date of the impression on the scan that states either of these categories as the diagnosis date? |
Answer revised 3/31/2022 Do not report cases based only on the TI-RADS category. The most recent information from ACR on TI-RADS indicates that neither TI-RADS 4 nor TI-RADS 5 is clearly defined as malignancy. TI-RADS 4 is "moderately suspicious" and TI-RADS 5 is "highly suspicious" but they do not specify what they are suspicious for. We need more information to determine reportability. |
