20210075 | Reportability: What American College of Radiology Reporting and Data Systems (RADS) can be used to determine reportability? See Discussion. |
LI-RADS (liver), PI-RADS (prostate), and TI-RADS (thyroid) can be used to determine reportability. BI-RADS (breast) and Lung-RADS cannot be used to determine reportability. Can these systems below to determine reportability? C-RADS (from CT colonography) NI-RADS (head & neck) O-RADS (ovarian-adnexal) |
The following cancer cases are reportable unless there is information to the contrary. –Liver cases with an LI-RADS category LR-4 (reportable since 2021) or LR-5 (reportable since 2016) –Prostate cases with a PI-RADS category 4 or 5 (reportable since 2017) The following are not reportable without additional information. –Breast cases designated BI-RADS 4, 4A, 4B, 4C or BI-RADS 5 –Lung cases designated Lung-RADS 4A," 4B, or 4X –Liver cases based only on an LI-RADS category of LR-3 –Colon cases with only C-RADS information (C-RADS category C4 is not reportable by itself) –Head and Neck cases with only NI-RADS information (NI-RADS category 3 is not reportable by itself) –Ovarian or fallopian tube cases with only O-RADS information (none of the O-RADS categories are reportable without additional information) –Thyroid cases with only TI-RADS information (none of the TI-RADS categories are reportable without additional information) |

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. |

20210006 | Behavior/Summary Stage 2018--Colon: What is the correct behavior and Summary Stage for a case of intramucosal adenocarcinoma arising in tubular adenoma? AJCC states this is Tis, though SEER Summary Stagie states this is Localized (code 1). The histology is 8140/2 (adenocarcinoma in situ), but the SEER Summary Stage is Locallized. |
Intramucosal carcinoma of the colon is assigned behavior code of /3. Intramucosal is not the same as in situ in terms of behavior. Behavior and staging are separate concepts, although there is some overlap. Use the instructions for coding behavior to code this field. Do not use stage to determine behavior in this case. For purposes of Summary Stage, intramucosal carcinoma is a localized lesion; however, for purposes of AJCC staging, assign Tis for the stage. |

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. |

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. |

20210057 | Reportability/Histology--Kidney: Is an oncocytic renal neoplasm of low malignant potential (ORNLMP) reportable? See Discussion. |
Kidney, right interpolar neoplasm, partial nephrectomy: Oncocytic renal neoplasm of low malignant potential (ORNLMP). Within part B, right interpolar kidney neoplasm, the neoplasm shows oncocytic features, with abundant granular eosinophilic cytoplasm and enlarged vesicular nuclei with prominent central nucleoli. The cells are arranged in small nests and tubules with hypocellular fibrous stroma identified within the background. Scattered binucleated cells are present, and rare cells with irregular nuclear membranes are present. No perinuclear halos or prominent cell membranes are present. Given the histologic features, the neoplasm is best classified as an oncocytic renal neoplasm of low malignant potential (ORNLMP). |
Oncocytic renal neoplasm of low malignant potential is not reportable. |

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). |

20210030 | Primary site--Breast: Patient was diagnosed with invasive ductal carcinoma of the left breast. Site of mass is 2:00 to 3:00. What is the correct site code, C504 upper outer quadrant (UOQ) or C50.8 (overlapping)? |
Assign C504, UOQ, for a left breast primary mass at 2:00 to 3:00. See the illustration in the SEER Coding Guidelines for breast, https://seer.cancer.gov/manuals/2021/AppendixC/Coding_Guidelines_Breast_2021.pdf |

20210051 | Primary site/Biliary tract--Ampulla of Vater: What is the correct primary site code for intra-ampullary and periampullary adenocarcinoma, C241 (8144/3) or C249? See Discussion. |
Ampulla, biopsy: High grade dysplasia with focal intramucosal carcinoma in a background of ulceration with acute and chronic inflammation. Surgery pathology: Head of pancreas, duodenum, and distal stomach, pancreaticoduodenectomy-Ampulla, Adenocarcinoma, intestinal type, intra-ampullary and peri-ampullary (mixed type). Grade moderately differentiated, 1.5cm. Tumor invades into duodenal submucosa. Lymphovascular Invasion: Foci suspicious for lymphovascular invasion identified. Perineural Invasion: Present. Synoptic report: Tumor Site Intra-ampullary and peri-ampullary (mixed type). Histologic Type Adenocarcinoma, intestinal type. There is not enough information regarding site in radiology reports or operative report. CT-A/P/C:The patient's known ampullary mass is not well visualized on this exam. No significant intrahepatic or extrahepatic biliary ductal dilation is identified. The pancreatic duct is normal caliber. |
Assign C241. Ampulla (C241) includes both periampullary and intra-ampullary. |

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. |
