20170026 | Multiple Primaries/Histology Rules/Multiple primaries--Kidney, renal pelvis: Are tumors diagnosed more than three years apart multiple primaries according to Rule M7 in a case with metastasis? See Discussion. |
5/27/02 Transurethral resection of bladder tumor (TURBT)--papillary transitional cell carcinoma, +lamina propria, no muscle invasion. All urine cytologies in 2011 and 2012 (only follow up received) show no malignancy. 3/11/15 Lung fine needle aspirate--poorly differentiated carcinoma consistent with urothelial carcinoma. 4/30/15 Renal pelvis biopsy--low grade papillary urothelial carcinoma, no lamina propria invasion, no muscularis propria invasion. |
Rule M7 applies. Abstract the bladder diagnosis and the renal pelvis diagnosis as separate primaries. The lung diagnosis is metastatic. The MP/H rules do not apply to metastatic tumors. |

20170073 | Histology/Behavior--Brain and CNS: How are histology and behavior coded for a diagnosis of pineal anlage tumor in an infant? See Discussion. |
Patient is an 11 month old with brain biopsy showing final diagnosis of pineal anlage tumor. How are behavior and histology coded for this rare tumor? |
Assign 9362/3 for pineal anlage tumors. According to the WHO Classification of Tumors of the Central Nervous System, 4th edition, pineal anlage tumors, while extremely rare, share features with pineoblastoma. Although they have a distinct morphology, there is no other ICD-O-3 code for pineal anlage tumors. |

20170060 | MP/H Rules/Histology/Grade--Unknown & ill-defined sites: What is the correct histology and grade of a liver biopsy with metastatic neuroendocrine carcinoma low to intermediate grade if primary site is unknown? See Discussion. |
CT-guided liver biopsy, diagnosis: Metastatic neuroendocrine carcinoma. Diagnosis Comment: Cytology of the tumor appears to be low to intermediate grade. Would this case be coded as an atypical carcinoid tumor (8249/3) based on SINQ 20170033 and the statement of intermediate grade; or should this be 8240/3 (neuroendocrine tumor) per SINQ 20160023 because it is a metastatic site? More clarification is needed on when to code 8249/3 or 8240/3 for a neuroendocrine carcinoma or neoplasm seen in a metastatic specimen only when there is specified grade. |
Assign histology code 8246/3 and assign code 9 for grade. Since the primary is unknown and the type of NEC is not definitively stated, code neuroendocrine carcinoma, NOS based on the diagnosis. Code grade from primary tumor only. Assign grade code 9 when the primary site is unknown. See instruction 2.b. in the Grade Coding Instructions for 2014+. SINQ 20170033 and SINQ 20160023 provide instructions for coding the grade/differentiation field. Using these SINQ questions to code histology could lead to errors. |

20170076 | MP/H Rules/Histology--Brain and CNS: Is meningioma with atypical features coded as meningioma (9530/0) or atypical meningioma (9539/1)? See Discussion. |
Pathology report microscopic description: The tumor is a meningothelial neoplasm (EMA+; BCL-2 and CD34 negative) with prominent collagen deposition. Necrosis and prominent nucleoli are present; no other atypical features are seen. Mitoses are present, up to 2 per 10 high-powered fields. Final Diagnosis: Dura, bicoronal craniotomy (specimen A): Meningioma with atypical features. There is no rule in benign brain and CNS section of Multiple Primary/Histology (MP/H) Rules stating to code the most specific histologic term when the diagnosis is (something less specific, i.e., adenocarcinoma). This rule is in other site chapters of MP/H but appears missing in the benign brain and CNS section. |
Code as meningioma, NOS (9530/0). This lesion has some of the features of an atypical meningioma (necrosis and prominent nucleoli), but it does not fit the definition of atypical meningioma in WHO Classification of Tumors of the Central Nervous System. Use text fields to document the details. |

20170057 | Grade: If the biopsy site is a higher grade, is the grade of the biopsy used over the grade of the surgical resection? See Discussion. |
When coding tumor grade, our pathologists have told us to code grade based on the specimen from the most definitive surgery or with the most amount of tissue, and that coding grade from the biopsy would not be appropriate even if it is a higher grade than from the surgical resection. Coding of solid tumors Instruction 5 states: If there is more than one grade, code the highest grade within the applicable system. Code the highest grade even if it is only a focus. Code grade in the following priority order using the first applicable system. |
For cases diagnosed prior to 2018: Use the Grade Coding Instructions to code grade. The instructions are intended to standardize coding of grade across the U.S. and to eliminate differences in opinion between pathologists. Standardized coding ensures that data can be combined and used for statistical analysis. You may code grade based on the biopsy when following the grade coding instructions. |

20170011 | MP/H Rules/Multiple primaries--Breast: Can we accession two breast primaries when imaging is "suspicious for malignancy" on both breasts but only one biopsy is taken and is histologically confirmed, and assume bilateral complete response to neoadjuvant chemotherapy with bilateral mastectomies negative for residual cancer? See Discussion. |
The patient is diagnosed by bilateral mammograms suspicious for malignancy in both breasts. A biopsy is done on one breast and is positive. The physician states that he will not biopsy the contralateral breast, as the patient has consented to bilateral mastectomy. The patient receives neoadjuvant chemo, follow by bilateral mastectomies. Both breasts are negative for residual cancer, stated as a complete response. Based on "suspicious for malignancy" can we accession two primaries and assume bilateral complete response? |
Accession two breast primaries, one right and one left, rule M7. "Suspicious" is reportable ambiguous terminology. |

20170078 | Scope of Regional Lymph Node Surgery--Lung: How do you code Regional Nodes Positive, Regional Nodes Examined, and Scope of Regional Lymph Node Surgery when a fine needle aspirate (FNA) or biopsy of supraclavicular lymph nodes is positive for a lung cancer primary? Supraclavicular lymph nodes are distant in SEER Summary Stage and regional by AJCC. See Discussion. |
There is a discrepancy in regional lymph nodes for lung between SEER and AJCC. Supraclavicular lymph nodes/cervical lymph nodes are distant for SEER but regional for AJCC. For SEER states, when there is an FNA or biopsy of a supraclavicular lymph node performed and it is positive for a lung primary and no other lymph nodes are examined, do you code 95 in Regional Nodes Positive/Regional Nodes Examined and code "1" for Scope of Regional Lymph Node Surgery or do you not count the FNA/biopsy of the supraclavicular lymph node since it is distant? |
For cases diagnosed through 2017, use the Collaborative Staging (CS) system to determine regional versus distant lymph nodes. Supraclavicular lymph nodes are regional for lung in CS. Please note that Summary Stage is not the same as EOD, CS, or AJCC staging. Registrars should not use Summary Stage definitions for anything other than directly assigning the Summary Stage field. |

20170019 | MP/H Rules/Histology--Testis: How should histology be coded for a mixed germ cell tumor that also includes choriocarcinoma now that non-seminomatous mixed germ cell tumors (9065) and seminomatous mixed germ cell tumors (9085) are collapsed for analysis? See Discussion. |
The MP/H Rules (Other Sites Terms and Definitions, Table 2) currently lists a separate mixed germ cell tumor code (9101) for germ cell tumors with choriocarcinoma plus teratoma, seminoma or embryonal carcinoma. Is this separate mixed germ cell tumor code still to be used now that all mixed germ cell tumors (9065 and 9085) have been collapsed into code 9085 for analysis per SINQs 20160056 and 20110013? The current WHO Classification for testis tumors does not list code 9101, but also collapses all seminomatous and nonseminomatous mixed germ cell tumors of more than one histologic type under code 9085. |
While WHO 4th Ed Tumors of Urinary and Male Genital System does not include 9101/3, this code has not been made obsolete. Follow the 2007 MP/H rules and code histology to 9101/3 per Other sites rule H16, Table 2. |

20170027 | MP/H Rules/Multiple primaries--Melanoma: Is a melanoma with an unknown laterality a different laterality for the purposes of applying Multiple Primaries/Histology Rule M4? See Discussion. |
8/1/2016 Left Abdomen biopsy: Early melanoma in situ (C445-2, 8720/2). 9/2/2016 Upper back: Superficially invasive malignant melanoma (C445-9, 8720/3). Does rule M4 apply and multiple primaries should be reported or does rule M8 apply and a single primary should be reported? |
Abstract multiple primaries following Multiple Primary Rule M4. Unknown laterality is a different laterality for the purposes of applying the MP/H rules for melanoma. NOTE: This answer applies to cases diagnosed prior to 2018. As of 1/1/2018, early melanoma is not reportable. |

20170075 | MP/H Rules/Behavior--Breast: How many primaries are to be abstracted for a patient with a history of left breast ductal carcinoma in situ (DCIS) diagnosed in 2014 and bone lesions showing metastatic carcinoma consistent with a breast primary in 2017? See Discussion. |
Patient was diagnosed with DCIS of the left breast in June 2014. The patient had a simple mastectomy with 2 axillary lymph nodes removed. The final diagnosis was intermediate to high grade ductal carcinoma in situ, predominantly micropapillary type, forming a 1.4 cm mass. No invasive carcinoma identified. Margins negative. In April 2017, the patient was found to have parietoccipital bone lesions, which were resected. The resulting diagnosis was metastatic carcinoma, morphologically consistent with breast primary " See Comment: The previous breast lesion is not available for review at the time of signout. However, the tumor is morphologically compatible with a breast primary. SINQ 20110111 would not make this is new primary. However, it seems that rule M8 might apply. An invasive tumor following an in situ tumor more than 60 days after diagnosis is a multiple primary. See Note 2: Abstract as multiple primaries even if the medical record/physician states it is recurrence or progression of disease. |
Assuming there were no other breast or any other tumors for this patient, change the behavior code to /3 on the original abstract for the 2014 breast primary. Similar to SINQ 20110111, there was likely a focus of invasion present in the original tumor that was not identified by the pathologist. The behavior code on the original abstract must be changed from a /2 to a /3 and the stage must be changed from in situ to localized. The MP/H rules do not apply to metastases. Therefore, rule M8 cannot be used. |
