20180002 | MP/H Rules/Multiple primaries--Urinary: Is a renal pelvis diagnosed 5/2016 a separate primary when the first invasive bladder was 12/2011? Per rule M7, the 5/2016 renal pelvis is more than 3 years later. Does Multiple Primary/Histology (MP/H) rule M7 refer back to the original diagnosis date or to the last occurrence? See Discussion. |
12/30/11 Bladder Biopsy: Diffuse carcinoma in situ of bladder, urothelial cancer at trigone (Stage T1) 1/30/2012 Transurethral resection of the bladder was non-papillary, urothelial carcinoma, focal invasion of lamina propria, staged T1 11/10/14, 9/28/15, 9/26/16, 10/19/17 all had positive bladder cytology of urothelial carcinoma 5/16/16 Left renal pelvis aspirate: positive for malignant cells, urothelial carcinoma 9/26/16 Left renal pelvis aspirate: positive for malignant cells, urothelial carcinoma 10/18/16-11/7/16 Bacillus Calmette-Guerin (BCG) x3 administered into the renal collecting system via ureteral catheter |
For cases diagnosed prior to 2018 This case is a single primary. This patient has not had a disease-free interval as demonstrated by the positive cytologies from 2014 through 2017. The MP/H rules cannot be applied in this case. To answer your question about the timing of rule M7, please see slide 6 in the Beyond the Basics MP/H advanced training, General Instructions, https://seer.cancer.gov/tools/mphrules/training_adv/SEER_MPH_Gen_Instruc_06152007.pdf |

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. |

20180031 | First Course of Treatment/Other Therapy: Where do you code Optune TTF therapy? What needs to be included in the text portion to document this treatment? |
Code OPTUNE in the Other Treatment field. See NovaTTF in SEER*Rx (http://seer.cancer.gov/seertools/seerrx/). NovaTTF is the pre-FDA approval name for OPTUNE. If OPTUNE was administered for recurrence, be sure NOT to record it in the first course of treatment fields. Check with CoC if you have questions about coding treatment for recurrence. |

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. |

20180092 | Reportability/Histology--Brain and CNS: Is diffuse intrinsic pontine glioma is reportable? If yes, what is the correct histology code? |
Diffuse intrinsic pontine glioma is reportable. For cases diagnosed in 2018, assign 9385/3. |

20180035 | Solid Tumor Rules (2018)/Multiple Primaries--Lung: How many primaries should be abstracted in this 2018 lung case? See Discussion. |
CT chest findings: 1. There is a dominant 1 cm. nodule in the left mid lung. 2. In addition, there is a new rather dominant bilobed nodule in the left lung base. 3. Distant metastases are not identified. Four months later, a doctor's note says routine follow-up visit status post Cyber Knife stereotactic body radiation therapy for synchronous early stage non-small cell carcinomas of the left upper and left lower lobes, both Stage IA. He is medically inoperable. This situation is described as a second primary tumor in AJCC8 page 438. However, by the 2018 Lung Solid Tumor rules, this would be a single primary, per rule M7. Is that correct? |
Abstract one primary per Rule M7. Follow the Lung Solid Tumor Rules to determine the number of primaries. The AJCC TNM manual is used for staging. Do not apply AJCC instructions to determine the number of primaries. |

20180054 | Solid Tumor Rules (2018)/Histology--Bladder: Under the Terms that are Not Equivalent or Equal section (Urinary Equivalent Terms and Definitions) it indicates noninvasive is not equivalent to papillary urothelial carcinoma and one should code the histology documented by the pathologist. However, many pathologists use Ta as both the description of the stage and the histology. Should this note be amended? See Discussion. |
The note in the Urinary Terms and Definition states, Both Ta and Tis tumors are technically noninvasive. Code the histology specified by the pathologist. While it is true that both Ta and Tis are technically noninvasive, the AJCC defines Ta specifically for, A pathologist's use of Ta does indicate the noninvasive carcinoma did arise from a papillary tumor. However, not all pathologists use terminology that, following the Urinary Solid Tumor Histology Coding Rules, will result in a histology coded to 8130, despite an AJCC-defined Ta (noninvasive papillary carcinoma) tumor having been diagnosed because the tumor projected from the wall on a stalk. In our region a number of pathologists provide the following types of diagnosis. Histologic type: Noninvasive. Histologic grade (WHO/ISUP 2016): High-grade. Tumor configuration: Papillary. The pathologist and/or physician may then stage this as Ta. How is the histology coded for these cases if the H Rules do not allow one to code the papillary and noninvasive Ta disease as not equivalent to noninvasive papillary carcinoma? Flat (in situ) urothelial carcinoma has an increased risk of invasive disease compared to the noninvasive papillary urothelial carcinomas. Will there be inconsistencies or a resulting impact to analysis of truly flat/in situ urothelial carcinoma vs. papillary urothelial carcinomas if the papillary tumors are not being coded as such? |
Per the April 2019 update: Noninvasive; papillary urothelial carcinoma; flat urothelial carcinoma Note: Noninvasive is not equivalent to either papillary urothelial or flat urothelial carcinoma. Both Ta and Tis tumors are technically noninvasive. Code the histology specified by the pathologist. |

20180008 | MP/H Rules/Multiple primaries--Thyroid: Is medullary carcinoma of the right lobe of the thyroid, with foci of papillary microcarcinoma in both lobes, one primary with mixed histology (8347/3) or two separate primaries? |
For cases diagnosed prior to 2018 Abstract two primaries, Medullary (8510/3) and papillary microcarcinoma (8260/3). Other sites rule M17 applies. |

20180015 | Histology--Ovary: What is the correct ICD-O-3 histology code for sertoliform endometrioid carcinoma of the ovary? |
Assign 8380/3. Sertoliform endometrioid carcinoma is a variant of endometrioid carcinoma according to the WHO Classification of Tumors of Female Reproductive Organs, 4th edition. There is no specific ICD-O-3 code for this variant. |

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. |
