20200058 | Surgery of Primary Site/Surgery Codes, NOS--Pancreas: What exactly is an extended pancreatoduodenectomy? Must the entire pancreas be resected in order to use code 70? What minimal requirements must be met to use code 70? How should a Whipple with cholecystectomy, partial omentectomy, common hepatic excision, portal vein resection, and lymphadenectomy be coded? |
According to our research, a pancreaticoduodenectomy (PD) includes an en bloc resection of the pancreatic head, the common bile duct, the gallbladder, the duodenum, the upper jejunum, the distal portion of the stomach and the adjacent lymph nodes. The extended PD procedure includes extended lymphadenectomy, extended organ resection, and extended vascular resection and reconstruction. Code 70 could be assigned without the entire pancreas being resected. A Whipple procedure removes the head of the pancreas, duodenum, stomach and gallbladder and part the common bile duct. The portal vein resection is probably part of the common bile duct excision. If the omentectomy was performed for treatment of this primary, record it in "Surgical Procedure of Other Site." Record the lymphadenectomy in the lymph node data items. |

20200054 | Solid Tumor Rules (2018)/Multiple primaries--Liver: When does a hepatocellular carcinoma (HCC) recurrence in the same area of the liver get accessioned as a new tumor following TACE/Y90/RFA? If there is a new HCC in the same area as previously treated but it is stated to be recurrent and/or progressive disease, is that evidence of a disease-free interval? If the tumor area is stated to be LR-TR and non-viable, but then a new HCC in that area is diagnosed, does that count as a disease-free interval? See Discussion. |
Example 1: 5/2013 diagnosis of HCC in segment 4B (single tumor), treated with microwave ablation in 7/2013. CT scan in 11/2017 with new 23mm hypodensity in liver segment 4 suspicious for recurrent disease. Clinical assessment in 1/2018: New enlarging lesion in liver most consistent with progression of HCC. Treated with RFA in 2/2018. Is the 2018 occurrence a new primary as imaging stated this was a new lesion? Example 2: 7/2017 diagnosis of HCC in right liver; 2.5 cm lesion in segment 5/6 with a couple of satellites and 12mm lesion in segment 6, treated with Y90 radioembolization. Follow-up note in 11/2017: complete response of treated cluster of lesions in segment 5/6 and lesion in segment 6, increase in size of caudate lesion not amenable for treatment (this lesion was stated to be indeterminate on 7/2017 imaging). Caudate lesion finally stated as LI-RADS5 on 3/2018 imaging and was treated with chemoembolization 6/2018. 7/2018 and 10/2018 Follow-up imaging states LR-TR nonviable lesion in caudate lobe. 8/2019 CT shows caudate lobe with arterial enhancement, new compared to prior imaging, LR-TR viable. MD note states patient has small local HCC recurrence in segment 1 (caudate lobe) with plan to repeat TACE. Is this 8/2019 HCC a new primary as the patient was disease free for greater than 1 year, or is it the same tumor and a single primary? |
Both examples are multiple primaries. Example 1: The 2018 lesion is a new tumor. Abstract multiple primaries based on 2018 Other Sites Solid Tumor Rules, Rule M10, when tumors are diagnosed more than one year apart. Example 2: 2017 diagnosis showed complete response to treatment. 2019 lesion is a new primary based on timing. The General Instructions of the Solid Tumor Rules instruct: Do not use a physician's statement to decide whether the patient has a recurrence of a previous cancer or a new primary. Each scenario should be evaluated separately using the rules as a guide. |

20200052 | Solid Tumor Rules (2018)/Histology--Prostate: How is the histology coded for a diagnosis of mixed prostatic adenocarcinoma (5%) and small cell neuroendocrine carcinoma (95%) from a transurethral resection of the prostate? See Discussion. |
Following the existing Solid Tumor Rules Histology Rules, it would seem this is a single primary with histology 8045 (Combined small cell carcinoma) because there is no indication there are multiple prostate tumors and Table 2 states combined adenocarcinoma and small cell carcinoma is Combined small cell carcinoma (8045). Conversely, while not an exact match to this case, SINQ 20190083 implies small cell carcinoma and adenocarcinoma of the prostate are separate primaries. In that SINQ case, the patient was simultaneously diagnosed with metastatic small cell carcinoma of the prostate on a liver biopsy and prostate adenocarcinoma on a prostate biopsy. There is no indication that patient had separate tumors in the prostate, however the SINQ instructs to code as separate primaries. Would the previous SINQ logic apply to synchronous diagnoses in the prostate as well? Or does code 8045 apply to this situation? |
Assign histology code 8045 for combined small cell carcinoma as this represents one tumor with mixed histologies using the 2018 Other Sites Solid Tumor Rules, Rule H16. |

20200009 | First course treatment/Surgery of Primary Site--Corpus uteri: Is an omentectomy performed with a hysterectomy for an endometrial primary site recorded under Surgery of Other Site? See Discussion. |
Per SEER 20140003, an omentectomy is not recorded under Surgery of Other Site when performed with a hysterectomy for an endometrial primary. Is this still correct? CoC appears to have different guidelines stating in a forum that an omentectomy is coded in data item Surgical Procedure to Other Site. I would like to confirm SEER guidelines. Is this one of those unique situations that SEER and STORE differ? Our state follows SEER guidelines and would like to communicate the appropriate rules to our facilities. |
Continue to record an omentectomy performed with a hysterectomy under Surgery of Primary Site and not as a separate procedure under Surgical Procedure of Other Site. The guidance In SINQ 2014003 and 20091118 is unchanged. |

20200060 | First Course Treatment/Reportability: Are there situations for which a case with a class-of-case code in the 30's should be reported to the central registry? We know these are not reportable to the CoC, but should they be reported to the central registry? See Discussion. |
Example: 3/22/2017-26 year old white female seen in the emergency room with abdominal pain. Patient was diagnosed about a month ago with breast cancer. Impression: menstrual pain. In this example the patient is newly diagnosed with breast cancer, but the second hospital does not treat or diagnose the patient; pain management for a separate condition is received only. Is this patient reported due to the history of active disease? |
Work with your central registry to determine which cases they require you to report. In general, any case still undergoing first course of treatment, even if not given at your facility, should be reported to the central registry. Many central registries will appreciate knowing that the patient was seen at your facility to update date last seen and other data items. |

20200080 | Reportability/Histology--Pancreas: Is a diagnosis of insulin-producing (insulinoma) epithelioid neoplasm reportable if made 2021 and later? If so, is the histology coded as 8151/3 per the ICD-O-3.2 Coding Table? See Discussion. |
The ICD-O-3.2 Implementation Guidelines and ICD-O-3.2 Coding Table indicate that insulinoma, NOS has changed behavior from /0 to /3 for cases diagnosed 2021 and later. However, the ICD-O-3.2 Implementation Guidelines do not indicate whether this change applies to tumors described as above. Insulinomas are generally neuroendocrine tumors/neoplasms, so it seems any neuroendocrine tumor described as an insulinoma should be collected as 8151/3, but does that apply to an epithelioid tumor/neoplasm also described as insulinoma? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
If the diagnosis includes insulinoma, it is reportable and coded 8151/3. Insulin-producing epithelioid neoplasm alone, without mention of insulinoma, is not reportable. |

20200041 | Reportability--Brain and CNS: Is an intradural T12/L1 capillary hemangioma reportable? See Discussion. |
Example: MRI found an intradural, extra-axial mass at T12/L1 with possible intramedullary component. Resection of the intradural intramedullary and extramedullary spinal cord tumor found a capillary hemangioma pathologically. The microscopic description on the path report describes a tumor with extensive vascularity involving the dura. Should we equate the statement of capillary to mean the tumor is arising in a blood vessel as we do for venous hemangioma (non-reportable per SINQ 20130001)? Or should it be reportable as C700, 9131/0 because it is described as involving the dura (intradural, intramedullary and extramedullary)? |
Reportability of capillary hemangioma depends on the site of origin. If it originates in the dura, it is reportable. If it originates in a blood vessel, it is not reportable. The site of origin is not clear in the information provided. Sites of involvement are mentioned, but not the site of origin. Capillary could refer to the site of origin or to the propensity of this tumor to form tiny blood vessels. If the site of origin cannot be confirmed as dura, do not report this neoplasm. |

20200066 | Reportability--Skin: Effective 2021, a cutaneous leiomyosarcoma is a related term for smooth muscle tumor, NOS (8897/1) in ICD-O-3.2. Currently, we have been capturing these as a C44_ (leiomyosarcoma, 8890/3) but the 2019 SEER inquiry states that atypical intradermal smooth muscle neoplasm (AISMN) was previously termed cutaneous leiomyosarcoma. This is not documented on the 2018 ICD-O-3 updates. Should this 2019 case be 8897/1 or 8890/3? |
Cutaneous leiomyosarcoma is reportable for 2019. Code histology to leiomyosarcoma 8890/3. As of cases diagnosed 1/1/2021, it is no longer reportable based on assignment to 8897/1 in ICD-O-3.2. |

|
20200056 | Reportability--Gallbladder: Is Intracholecystic papillary neoplasm (ICPN) with low-grade intraepithelial neoplasia reportable? The primary site is gallbladder. |
Intracholecystic papillary neoplasm (ICPN) with low-grade intraepithelial neoplasia is not reportable. The WHO assigns a behavior of 0 to these neoplasms. |

20200079 | Solid Tumor Rules (2018)/Primary Site--Brain and CNS: Should the updated note for optic nerve glioma be included in both the 2018 Solid Tumor Rules for Malignant Central Nervous System (CNS) and Peripheral Nerves, Note 6, and the Non-Malignant CNS Tumors, Note 5? See Discussion. |
Should the updated Note 5 from the Non-malignant CNS regarding optic nerve glioma also be incorporated into Note 6 for Malignant CNS rules (the pilocytic astrocytoma note)? This was one of the major issues identified in the SEER*Educate Workshop. Registrars have demonstrated they do not consistently think to look at the Non-malignant CNS schema when they see the term glioma and continue to misclassify optic nerve gliomas as malignant. This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
The 2022 Solid Tumor Update will include a new note in the Terms & Definitions, Introduction section that will state: See the Non-malignant CNS rules when the primary site is optic nerve and the diagnosis is either optic glioma or pilocytic astrocytoma. The behavior is non-malignant and coded 9421/1. |
