20180047 | Reportability--Kidney: Is a hybrid oncocytic tumor reportable? See Discussion. |
10/27/2017 partial nephrectomy final path diagnosis: renal oncocytic neoplasm, favor hybrid oncocytic tumor. Comment: |
Do not report renal HTOC. According to our expert pathologist consultant, "the genetic studies seem to indicate that the chromosomal changes of chromophobe renal carcinoma are not found in the hybrid tumors." |

20180096 | Reportability/Histology--Small intestine: Is a neuroendocrine microtumor of the duodenum a reportable tumor? See Discussion. |
This comment was added to the pathology report by the pathologist: A focus of neuroendocrine microtumor measured 350 micrometers, qualifying as a neuroendocrine microtumor. Focus was immunohistochemically positive for chromogranin and synaptophysin and negative for gastrin. The Ki-67/CD45 immunostain showed <1% positivity in microtumor. |
Neuroendocrine microtumor of the duodenum is reportable as 8240/3. "Microtumor" pertains to the size/amount of NET and not to a histologic type. |

20180034 | Reportability--Vulva: Is a biopsy showing high grade squamous intraepithelial lesion (VIN II) in the vulva reportable for cases diagnosed in 2018? See Discussion. |
In comparison to SINQ 20180022, this case does not mention VIN III anywhere in the final diagnosis. Is any mention of HGSIL in the final diagnosis reportable, even if it is qualified with a non-reportable term in parenthesis or CAP protocol? |
Since this HSIL diagnosis is specified as VIN II, do not report it. WHO includes both VIN II and VIN III as synonyms for HSIL of the vulva. HSIL is reportable and VIN III is reportable. VIN II is not reportable. |

20180001 | Reportability/Date of diagnosis--Small intestine: Is this case reportable? Widely metastatic gastrointestinal stomal tumor (GIST) was diagnosed at an out-of-state facility in 2017 and referred back to a hospital in our state for chemotherapy where there is a history of a small bowel resection of GIST of uncertain malignant potential (8936/1) doneat the hospital in 2003. If so, is the diagnosis date 2003 or 2017? See Discussion. |
The hospital registrar reports that the case was identified at the hospital because of the referral for chemotherapy for the metastatic GIST. The records from the out-of-state hospital mentioned a history of a small bowel resection in 2003 for a borderline tumor. The registrar went back through the hospital's old records and found the surgery was done for GIST of low malignant potential at her facility. The question is whether to report the case or not, and if reported, is 2003 the diagnosis date. The rules say to change the behavior and backdate the diagnosiswhen a tumor is presumed benign and islater diagnosed as malignant. Another problem for this case is that the out-of-state hospital did not review the slides from the 2003 surgery. |
Report the case with a diagnosis date of 2017. The 2003 diagnosis was not reviewed, and there are no physician statements that cancer was present in 2003, or that the metastases are attributable to the 2003 diagnosis. Document the details of the case in text fields. |

20180012 | First course of treatment: What is the correct code to use for allogenic stem cell transplant? |
Code an allogenic stem cell transplant as 20 (Stem cell harvest (stem cell transplant) and infusion) in Hematologic Transplant and Endocrine Procedures in the 2016 SEER Manual. |

20180094 | Reportability--Prostate: According to the 2018 SEER Program Manual, a prostatic intraepithelial neoplasia (PIN) III is not reportable, but is an atypical small acinar proliferation (ASAP) PIN 4 reportable? |
ASAP is not reportable. Patients with ASAP found on needle biopsy will likely undergo another biopsy. |

20180057 | Solid Tumor Rules (2018)/Histology--Bladder: Which Solid Tumor H Rule applies when the patient has a single tumor removed by transurethral resection of bladder tumor and the final diagnosis is: Carcinoma of the bladder with the following features: Histologic type: Urothelial carcinoma? See Discussion. |
Instruction number 1 under the Coding Multiple Histologies instructions states to code histology when the histology is described as subtype, type or variant. The general rules do indicate we can code the histology identified as type, but when applying the H Rules, it seems an argument could be made for either H1 or H3. H1 applies if you ignore the diagnosis of carcinoma and only code the histologic type: urothelial carcinoma. However, the rules do seem to imply that you take all histologies into account (e.g., code the subtype/variant when there is a not otherwise specified (NOS) and single subtype/variant). Following this logic, Rule H3 seems to be the only rule that fits, and one would code the subtype/variant urothelial carcinoma when the diagnosis is carcinoma NOS, histologic type: urothelial carcinoma. The problem is that urothelial carcinoma is not a subtype/variant of carcinoma (NOS) per Table 2. The entry for Carcinoma NOS in Table 2 states, Subtypes of carcinoma NOS include adenocarcinoma and all subtypes/variants of adenocarcinoma. To some, urothelial carcinoma is a more specific type of carcinoma; however, urothelial carcinoma is not also listed as a subtype of carcinoma or of adenocarcinoma; only adenocarcinoma is categorized as a subtype of carcinoma. Consistently applying the rules becomes an issue when rules are interpreted in different ways. Should this Table be amended to include urothelial carcinoma as a subtype/variant of carcinoma NOS with the same caveat given to adenocarcinoma in Table 2? |
Code the most specific histology or subtype/variant. Urothelial carcinoma is more specific than carcinoma. See instruction #1 on page 29 of the April 2019 update. |

20180105 | 2018 Solid Tumor Rules/Histology--Lung: What is the appropriate histology code for the case below in the Discussion section? Is there a difference between adenocarcinoma in situ (bronchioloalveolar carcinoma), non-mucinous type (8252/2) and adenocarcinoma in-situ, mucinous? See Discussion. |
Procedure: Wedge, resection specimen, Laterality: Right, Tumor site: Right upper lobe, Tumor size: 1.0 cm in greatest dimension, Histologic type: Adenocarcinoma in-situ, mucinous, Histologic grade: N/A, Visceral pleura invasion: Not identified, Tumor extension: N/A, Margins: Uninvolved, Lymphocytosis. |
Assign 8253/2 for adenocarcinoma in situ, mucinous. New codes were added in 2018 for mucinous adenocarcinoma in situ for lung cancer only as all cases were not invasive. Pathologist are discouraged from using the term BAC. In-situ lung tumors can now be identified as either mucinous or non-mucinous and the appropriate ICD-O code should be assigned based on diagnosis. |

20180006 | MP/H Rules/Histology--Breast: Should encapsulated papillary carcinoma of the breast with a separate focus of ductal carcinoma in situ be coded as 8050/2 (papillary carcinoma) and staged as in situ? See Discussion. |
Pathology--Right breast, lumpectomy with needle localization: Encapsulated papillary carcinoma of the breast. A separate focus of ductal carcinoma in situ is present. Sentinel lymph node, right breast, biopsy: One lymph node, negative for malignancy. No metastatic carcinoma is seen on slides stained with immunostain for cytokeratin (AE1/AE3). Specimen laterality: Right. Tumor size: 1.2 cm. Histologic type: Encapsulated papillary carcinoma. Nuclear grade: Grade 1 (low). Mitotic rate: Score 1. Ductal carcinoma in situ (DCIS): DCIS is present. Estimated size (extent) of DCIS: 3 mm. Architectural patterns: Cribriform and papillary. Nuclear grade: grade 1 (low). Necrosis: Not identified. Margins: Margins uninvolved by encapsulated papillary carcinoma. Distance from closest margin: 8 mm, superior Margins uninvolved by DCIS. Distance from closest margin: 11 mm, superior Lymph nodes: Total number of lymph nodes examined (sentinel and nonsentinel): 1. Number of sentinel lymph nodes examined: 1. Number of lymph nodes with tumor cells: 0. Pathologic staging: Primary tumor: See comment. Regional lymph nodes: pN0(i-). Comment: In the WHO Classification of Tumours of the Breast (2012), it is stated that "there is no universal agreement on how to stage encapsulated papillary carcinomas. In the absence of conventional invasive carcinoma, the consensus of the WHO Working Group was that such lesions should be staged and managed as Tis disease." |
For cases diagnosed prior to 2018 Code as encapsulated papillary carcinoma, 8504/3; this is a synonym for intracystic carcinoma (WHO Classification of Tumors of the Breast). Stage this case as invasive. |

The Solid Tumor Rules for Lung rule H4 applies. Per Table 3, page 12, third column on adenocarcinoma row, adenocarcinoma, acinar predominant is coded to 8551/3. |
