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." |

20180037 | Date of Diagnosis--Colon: If a patient has a positive Cologuard test, is the date of diagnosis the date of the cologuard test or the date of the biopsy? |
Do not use the date of a positive Cologuard test as the date of diagnosis. |

20180079 | Solid Tumor Rules/Multiple primaries--Breast: How many primaries should be abstracted when papillary carcinoma is identified in two biopsies and a subsequent lumpectomy identified invasive ductal carcinoma with multifocal ductal carcinoma in situ (DCIS)? See Discussion. |
The right breast ultrasound shows a 1.4 cm mass at 8 o'clock and a separate mass .6 cm at 7 o'clock (site code for both C50.5). Pathology report: Right 8 o'clock core needle biopsy fragments of intracystic noninvasive papillary carcinoma (8504/2), right 7 o'clock core needle biopsy fragments of intracystic noninvasive papillary carcinoma (8504/2). Then, another facility performs a right breast lumpectomy (operative note not available). Outside Facility: Right breast lumpectomy pathology shows invasive ductal carcinoma .6cm (8500/3) multifocal DCIS .5cm greatest dimension tumor site right breast NOS. Should we use Rule M12-Abstract multiple primaries when separate/non-contiguous tumors are on different rows in Table 3 in the Equivalent Terms and Definitions. Timing is irrelevant. Note: Each row in the table is a distinctly different histology. So would this be two primaries C50.5 (8504/2) and C50.9 (8500/3)? |
Abstract as multiple primaries using Breast Solid Tumor Rule M12 as these are separate, non-contiguous tumors on different rows in Table 3. |

20180066 | Solid Tumor Rules (2018)/Laterality--Brain and CNS: How is laterality coded for bilateral non-malignant central nervous system (CNS) or malignant CNS tumors now that laterality is no longer used to identify these tumors as multiple primaries? See Discussion. |
The Equivalent Terms and Definitions sections in the Solid Tumor Rules for these schemas identify which sites must have laterality coded, but there is no instruction for coding laterality when bilateral tumors are a single primary. The SEER Manual currently only indicates code 4 (bilateral) is seldom used (e.g., bilateral ovarian tumors, Wilms tumors, etc.) but does not indicate laterality code 4 should be used for CNS tumors. Is this note going to be updated or should a non-bilateral code be applied? Example: MRI demonstrates multiple left-sided dural-based meningiomas including a 4.4 cm left posterior fossa meningioma, a 0.8 cm left frontal-parietal meningioma and a right posterior frontal meningioma. The large left posterior fossa meningioma was resected and proved atypical meningioma. Should the laterality be 4 (bilateral) as the patient had both left and right-sided meningiomas confirmed to be a single primary? Or should the laterality be coded as 2 (left) since only the large left-sided meningioma was proven to be a borderline tumor (atypical meningioma, 9539/1) and the others were benign? |
Determine whether the CNS tumors are single or multiple primaries. Multiple cerebral meningiomas are a single primary according to the non-malignant CNS Solid Tumor Rules. Assign laterality using the 2018 SEER Manual for select invasive, benign, and borderline primary intracranial and CNS tumors using codes 1-9 for all sites listed in the Sites for Which Laterality Codes Must Be Recorded table. In the example, assign code 4, bilateral involvement at time of diagnosis, lateral origin unknown for a single primary. The solid tumor rules are not a one-stop-shop for all coding. Refer to the appropriate coding manual for laterality. We removed laterality for determining multiple primaries in meningiomas as they were being over-reported according to CBTRUS. |

20180069 | Solid Tumor Rules (2018)/Behavior--Brain and CNS: The Behavior coding instructions in the Non-Malignant Central Nervous System (CNS) Equivalent Terms and Definitions section refer to Table 1 for help coding behavior when the other priority order instructions do not apply; however, the behavior cannot be reasonably determined using Table 1 alone for all WHO Grade I neoplasms. Should an additional default, such as the ICD-O-3 or Tables 5 and 6, be used to determine behavior? See Discussion. |
Similar to an issue previously submitted SINQ 20180063, Table 1 (WHO Grades of Select CNS Neoplasms) in the Non-Malignant CNS Equivalent Terms and Definitions section states WHO Grade I tumors are always non-malignant. However, this does not mean that the tumors listed in Table 1 as WHO Grade I are always benign (/0). Some tumors listed with a WHO Grade I have a behavior of /1 (borderline) per the ICD-O-3 and/or Tables 5 and 6. The Behavior coding instructions do not currently indicate these are the appropriate sources to use when the pathologist and/or physician do not comment on the behavior of these tumors. In our area, pathologists do not explicitly state the behavior for these tumors; the pathologist only assigns the WHO Grade. |
There is no way for us to know what behavior to assign WHO grade II tumors when the pathologist does not provide that information. Defaulting to either benign or malignant is incorrect. Please follow back with the pathologist to determine behavior. The behavior must be non-malignant, meaning /0 or /1, or the tumor is a WHO Grade 1, to be reportable as non-malignant CNS tumor. Refer to Table Instructions under Table 1, WHO Grades of Select CNS Neoplasms that says to use non-malignant CNS rules for all WHO Grade 1 tumors and to use the appropriate rules for WHO Grade 2 tumors Use ICD-O and all updates if not listed in Table 6 according to non-malignant CNS Histology Rule H3 (for single tumor) and Rule H8 (for multiple tumors) when only one histology is present. |

20180050 | Reportability/Heme & Lymphoid Neoplasms: Is monoclonal B-cell lymphocytosis reportable? See Discussion. |
We noticed this term was added to the most recent version of the Heme Database (DB) as an alternate name for chronic lymphocytic leukemia/small lymphocytic lymphoma; however we do not recall being notified that this was a new reportable term for code 9823 and the term was not included in the 2018 ICD-O-3 Histology updates. The Definition in the Heme DB for Chronic lymphocytic leukemia/small lymphocytic leukemia (CLL/SLL) includes information that the term was added in the 2016 WHO revision, thus would be reportable back to 2016, is that correct? In addition, the Definition seems to be describing it as a precursor condition to CLL and may never actually evolve into CLL, so it is unclear if this term should really be reportable. Example: 09/08/2016 Onc Note: A/P: monoclonal B-cell lymphocytosis of undetermined significance (MBL): I reviewed with him the results of the bone marrow biopsy. Interestingly, there is no evidence of abnormal plasma cell population by flow cytometry and immunohistochemistry. Nevertheless, flow cytometry does demonstrate a very small population of abnormal and monoclonal B-cell lymphocyte population with immunophenotype consistent with CLL/SLL. Given the very low number of the abnormal B cells, this can be categorized as monoclonal B-cell lymphocytosis (MBL). I recommend surveillance visit in one year. 9/12/2017 Onc note: A/P: Monoclonal B-cell lymphocytosis of undetermined significance (MBL) and IgM MGUS. No symptoms concerning for active disease or progression. Explained that MBL is a very indolent process. Patients with CLL-phenotype MBL progress to CLL at a rate of ~1-2 percent per year. Follow-up in 1 year. Is this case reportable? |
Monoclonal B-cell lymphocytosis is not a reportable condition. This term will be removed from 9823/3 since it is a /1 (has it's own code). This will become much more clear once we get the new WHO Heme terms into the database. |

20180076 | Solid Tumor Rules (2018)/Histology--Head & Neck: Where does cytology rank on the Priority Order for Using Documentation to Identify Histology for Head and Neck primaries? See Discussion. |
Cytology is not listed in the Priority Order for Using Documentation to Identify Histology (Histology Coding Rules) in the Head and Neck schema. Other schemas do include cytology in the hierarchy below tissue from a biopsy or resection. Cytology is often less specific than histology, so one would expect cytology to be listed below tissue in this hierarchy. Was this an oversight? Or would cytology be equivalent to histology if it provided the most specific histology for the case? |
Instruction #5 in the Priority Order for Using Documentation to Identify Histology of the Head and Neck Solid Tumor Rules, Item 5.B., refers to cytology in the documentation though cytology is not listed before this. In H&N tumors, cytology is usually performed on lymph nodes and seldom on a primary tumor. Cytology will be added to H&N in the next 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. |

20180013 | Reportability--Brain and CNS: Are tuberous sclerosis cancers found in the brain reportable? See Discussion. |
I have searched ICD-O-3 for a histology listing but could not locate. I also searched the SEER Inquiry database for possible answers, but none were found. The patient underwent a pediatric MRI of the brain of which final impression was: 1) Subependymoma nodules, cortical tubers, and SEGAs are seen bilaterally consistent with tuberous sclerosis. |
SEGA (Subependymal giant cell astrocytoma) is reportable if diagnosed in 2004 or later. Tuberous sclerosis complex (TSC) is not a neoplasm and is not reportable. SEGA is a neoplasm that commonly occurs in TSC patients. Refer to the reportability instructions on pages 5-7 in the SEER manual, https://seer.cancer.gov/manuals/2016/SPCSM_2016_maindoc.pdf |

20180018 | MP/H Rules/Histology--Brain and CNS: How should histology be coded for the following 2017 cases (pituitary adenoma vs. prolactinoma)? See Discussion. |
1. (2017) Pituitary mass resection with a path diagnosis of Do we code as prolactinoma when the tumor is immunoreactive for prolactin or must there be a definitive statement of ? 2. (2017) Pituitary lesion on imaging, MD diagnosis of Current (2007) MP/H rule H9 states when there are multiple histologies in the same branch in Chart 1, code the more specific histology. These histologies are NOT in Chart 1, but prolactinoma seems to be a more specific type of pituitary adenoma. The next rule, H10 states to code the numerically higher code, 8272/0 (pituitary adenoma)? 3. (2017) Imaging diagnosis of pituitary macroadenoma with clinical diagnosis by MD of macroprolactinoma. Current rules indicate when there is no path specimen that physician reference to type of tumor has priority over imaging. Will these answers/histologies change with the upcoming 2018 Solid Tumor rules? |
Code each of these 2017 cases as prolactinoma (8271/0), the more specific histology. If these cases were diagnosed in 2018, the answer would be the same: code as prolactinoma. |
