20160011 | Reportability--Stomach: Are microcarcinoid tumors reportable? See discussion. |
SINQ 20081076 states carcinoid tumorlets of the lung are not reportable and are defined as being less than 5 mm in diameter and benign. Per the WHO Classification of Digestive Tumours, microcarcinoid tumors are precursor lesions/nodules measuring greater than 0.5 mm, but less than 5 mm (0.5 cm). Is the term microcarcinoid tumor equivalent to carcinoid tumorlet, and therefore not reportable? Or is a microcarcinoid tumor a reportable type of neuroendocrine tumor (NET)? |
Microcarcinoid and carcinoid tumors are reportable. The ICD-O-3 histology code is 8240/3. Microcarcinoid is a designation for neuroendocrine tumors of the stomach when they are less than 0.5 cm. in size. Neuroendocrine tumors of the stomach are designated carcinoid when they are 0.5 cm or larger.
The term microcarcinoid tumor is not equivalent to carcinoid tumorlet. |

20130150 | MP/H Rules/Histology--Bladder: What is the histology code histology code for a bladder TUR that demonstrates mixed invasive urothelial and small cell carcinoma? See Discussion. |
SINQ 20041104 (prior to 2007 MP/H rules) states to code histology to 8045. The MP/H rules do not address this combination of urothelial and small cell carcinoma. The current MP/H rule that applies is Rule H8, code the higher histology (8120/3). However, if the histology is coded to 8120/3, the fact that small cell carcinoma exists will be lost. If the small cell carcinoma drives the treatment plan/prognosis, shouldn't this situation be reflected in the rules for coding histology? |
Code the histology to 8045/3 [mixed small cell carcinoma]. The presence of small cell carcinoma drives the treatment decisions for this case.
This issue will be addressed in the next revision of the MP/H rules. |

20240030 | Reportability/Primary Site--Skin: Is squamous cell carcinoma (SCC) that overlaps skin and the vermillion border reportable when the percent of overlap is unknown? See Discussion. |
SINQ 20031110 addresses an overlapping lip lesion between skin and the vermillion border. We were instructed to go with area of greatest involvement. Case would be reportable if >50% of tumor was on the vermillion border and site would be coded to vermillion border (C00._). Often times percentage of involvement is not stated and all that is known is that the lesion overlaps skin and mucosa. |
Determine whether the lesion is on the mucosa or skin based on the pathology report, history and physical, and operative notes when available. The gross description of the pathology report should include information to help in determining whether the site of origin is epithelium (skin) or mucosa (lip). Do not report the case when the site of origin cannot be determined between a reportable site and non-reportable site for this histology. This includes situations where the site of origin or the site with the greatest involvement is undetermined. In this case, you cannot confirm reportability. |

20100110 | Reportability--Esophagus/Stomach: Are the terms "high grade dysplasia" and "severe dysplasia" synonymous with in situ for tumors in the gastrointestinal tract? See Discussion. |
SINQ 20000245 states that high grade or severe dysplasia in not synonymous with in situ disease. However, per page 109 in the 7th edition of AJCC Cancer Staging Manual, high grade dysplasia is the only term listed under Tis. A note on that page explains that "high-grade dysplasia includes all noninvasive neoplastic epithelia that was formerly called carcinoma in situ, a diagnosis that is no longer used for columnar mucosae anywhere in the gastrointestinal tract."
There has been considerable pressure from registrars at larger reporting facilities to re-address this issue. The pathologists at these facilities state that they are correctly documenting the presence of in situ disease when they use the term high grade dysplasia for gastrointestinal tract tumors. In their opinion, it is not necessary to add the term in situ in parentheses following the use of the term high grade dysplasia to clarify the behavior of these lesions in their pathology reports. If the term "carcinoma in situ" is no longer being used by many pathologists for sites in the gastrointestinal tract, won't this lead to underreporting of in situ disease for these sites unless the reportability guidelines are changed? |
For cancer reporting purposes, the terms "high grade dysplasia" and "severe dysplasia" are not synonymous with in situ for tumors in the gastrointestinal tract. These cases are only reportable when the pathologist documents carcinoma in situ or intraepithelial neoplasia grade III, or when the registry includes in their policies and procedures the pathologist's statement that he/she uses HGD to mean the same as CIS.
Reportability laws are customarily based on ICD-O. Because "high grade dysplasia" and "severe dysplasia" are not designated as in situ in the ICD-O, there is no legal authority to report these cases in most states.
NAACCR is reviewing this issue. See #5 on page 11 of the December 1, 2013 NAACCR Implementation document, http://www.naaccr.org/LinkClick.aspx?fileticket=u7d3sB71t5w%3d&tabid=126&mid=466 |

20061009 | CS Site Specific Factor--Breast: If there are two ER/PR tests, one positive and one negative, which result should be coded in the SSF fields 1 and 2? See Discussion. | SINQ #20021074 states that for cases up to 2003, if there are differences in ER/PR results, to code the positive findings over the negative findings. Does this hold true for coding SSF1 & SSF2 for breast? Scenario: 10/19 Breast bx: ER + PR -; No date/specimen: ER/PR -; 12/3 Partial Mast: ER/PR + |
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2. For cases diagnosed prior to January 1, 2007, according to the CS Steering Committee, record the pathologist's interpretation of the assay value for the most representative tumor specimen. This may require conversation with the pathologist when specimen size is not specified. |

20210054 | Tumor Size--Clinical/EOD 2018--Prostate: How is Tumor Size--Clinical coded when there is an incidental finding of prostate cancer on prostatectomy for another reason? See Discussion. |
SEER*RSA states EOD Primary Tumor should be coded to 800 for an incidental finding of prostate cancer on prostatectomy for other reasons. The SEER Manual states to assign code 000 for Tumor Size--Clinical when EOD Primary Tumor is coded to 800; however, the definition for Tumor Size--Clinical indicates clinical classification is composed only of diagnostic workup prior to treatment. If there is no clinical workup for an incidental finding of prostate cancer, code 000 does not seem appropriate (does not meet criteria for clinical classification). Code 999 seems more appropriate for incidental findings during surgery for other reasons. The SEER Manual does not provide this exception in the current instruction. |
Assign code 000 for Tumor Size--Clinical when EOD Primary Tumor is coded 800 (No evidence of primary tumor). Code 000 indicates no tumor was found since there was no clinical workup to identify this incidentally found cancer. This is a special instruction for cases coded 800 in EOD Primary Tumor. Text fields can be used to record details. |

20021002 | Histology (Pre-2007)--Breast: What code is used to represent the histology "ductal carcinoma in situ with comedo necrosis"? See discussion. | SEER distributed breast questions to the Advisory Group made up of pathologists from different SEER regions. One question dealt with the terms comedo type, comedo necrosis and comedocarcinoma. Per the Advisory Group, "Do not code comedo necrosis. These three phrases each represent a different level of diagnosis and can't be compared. "Comedocarcinoma" is an established diagnosis of in situ carcinoma and should be coded as such. "Comedo type" refers to a type of intraductal cancer; whether it is considered to be a true diagnosis is probably still equivocal. "Comedo necrosis" refers to a description of cellular pathological events that occasionally occur within an intraductal tumor of comedo type, which should not be coded at all."
Per the SEER preferred answer: Comedo type = comedocarcinoma. Ignore comedo necrosis. |
For tumors diagnosed prior to 2007:
Code the Histology field to 8500/2 [ductal carcinoma in situ].
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

20160028 | MP/H/Histology--Sarcoma: How should Ewing Sarcoma/primitive neuroectodermal tumor (PNET) be coded for a 2012 case? See Discussion. |
SEER SINQ 20031051 applies to cases diagnosed before 2007 and advises: Code histology as 9260/3, Ewing sarcoma. Ewing sarcoma is a specific histology on the continuum of primitive neuroectodermal tumors. Code Ewing sarcoma as it is more specific than PNET, NOS.
For tumors diagnosed 2007 or later, refer to the MP/H rules. |
Apply 2007 MP/H rule H6 and assign the numerically higher ICD-O-3 code that reflects PNET (9364/3). According to the WHO Tumors of Soft Tissue and Bone, though Ewing sarcoma ICD-O-3 code is 9260/3, Ewing sarcoma with a higher degree of neuroectodermal differentiation present is classically termed peripheral neuroectodermal tumors (PNET). WHO does not offer guidance how to classify tumors stated to be Ewing sarcoma PNET.
Histology code 9364/3 is assigned for a Ewing/PNET that arises outside of the brain/CNS. Peripheral neuroectodermal tumor (PNET) and peripheral primitive neuroectodermal tumor (PPNET) are Ewing family tumors.
Histology code 9473/3 (PNET, primitive neuroectodermal tumor, central primitive neuroectodermal tumor, or supratentorial PNET) is only used for tumors arising inside the brain/CNS. |

20240026 | Update to Current Manual/Reportability--Pancreas: For cases diagnosed 2024+, is a diagnosis of pancreatic intraepithelial neoplasia II (PanIN II) reportable? If so, how should histology be coded? See Discussion. |
SEER Program Coding and Staging Manual: Reportability – Reportable Diagnosis List indicates pancreatic intraepithelial neoplasia (PanIN II) (C250-C259) is reportable. However, the ICD-O-3.2 lists “Glandular intraepithelial neoplasia, grade II” and “Glandular intraepithelial neoplasia, low grade” as histology code 8148 with behavior of /0 (benign). |
Do not report PanIN II. WHO Classification of Digestive Tumors, 5th edition, now categorizes PanIN into two categories, low grade (8148/0) and high grade (8148/2). PanIN grade I and PanIN grade II are categorized as PanIN low grade; PanIN grade III is categorized as PanIN high grade. We will update the Reportability section of the manual. |

20240021 | Solid Tumor Rules/Reportability/Histology--Digestive Sites: Is a diagnosis of “high grade dysplasia” (not specified to be squamous or glandular) reportable for esophagus, stomach, and small intestine for cases diagnosed beginning in 2024? If so, how should histology be coded? See Discussion. |
SEER Program Coding and Staging Manual indicates high grade dysplasia of esophagus, stomach, and small intestine are reportable. The ICD-O-3.2 does not include “high grade dysplasia” as equivalent to “high grade squamous dysplasia.” If reportable, would high grade dysplasia (NOS) that originates in the stomach and small intestine default to 8148/2, while esophageal high grade dysplasia (NOS) default to 8077/2? |
Report these high grade dysplasia of the following organs as stated below. Stomach: Assign code 8148/2 glandular intraepithelial neoplasia, high grade using the Other Sites Solid Tumor Rules, Table 6: Stomach Histologies and as described in the WHO Classification of Digestive Tumors, 5th edition. Small intestine and Esophagus: Assign code 8148/2 glandular intraepithelial neoplasia, high grade, using the Other Sites Solid Tumor Rules, Other Sites Histology Rules, Rule H4/H26. The following note is listed for both of these rules. Note: This list may not include all reportable neoplasms for 8148/2. See SEER Program Coding and Staging Manual or STORE manual for reportable neoplasms The Other Sites Solid Tumor Rules, Table 5: Esophagus Histologies and Table 7: Small Intestine and Ampulla of Vater Histologies will be updated to reflect this code as time permits. |
