20170012 | Primary Site/Sarcoma--Breast: How should the primary site and stage be coded for osteosarcoma of breast? Is C509 correct or should the code be a different primary site? When assigning C509, the Collaborative Stage (CS) still pertains to breast cancer and AJCC stages it as a breast cancer and not as a sarcoma. |
Code primary osteosarcoma of the breast to breast, C500-C509. Not all site and histology combinations can be staged in CS or AJCC. 9180/3 of breast cannot be staged using the CS breast schema. Breast (C500-C509) cannot be staged using the CS soft tissue schema. The same is true for AJCC. You can stage this case using SEER Summary Stage. Important: Do NOT change the primary site or histology code based on whether or not the case can be CS or AJCC staged. We need to know how many cases are unable to be staged because of their primary site and histology combinations. |

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. |

20170045 | Reportability--Brain and CNS: Is meningioangiomatosis reportable as meningiomatosis (9530/1) or angiomatous meningioma (9534/0)? See Discussion. |
Pathology report: Brain tumor, left side: Gliotic cortex and subcortical white matter with meningioangiomatosis (see Comment). Comment This specimen represents a meningioangiomatous lesion located in the leptomeninges that projects along the Virchow-Robin spaces into the underlying cortex. The surrounding brain parenchyma demonstrates reactive changes with astrogliosis and microgliosis. An intraparenchymal neoplasm is not seen. Meningioangiomatosis is a rare benign meningovascular hamartomatous condition and usually appears in young patients. |
Meningioangiomatosis is not reportable. It is a cortical lesion which may occur sporadically or in NF2 (neurofibromatosis type 2). It is not listed in ICD-O-3. |

20170031 | MP/H Rules/Multiple primaries--Penis: How many primaries should be reported for a diagnosis of invasive squamous cell carcinoma (SCC) of the penis in 6/2011, treated with excision and fulguration followed by 10/2014 penile lesion found to be SCC with basaloid features focally highly suspicious for invasion? Clinically, the 2014 tumor is stated to be in situ and recurrent penile cancer and follow-up in 2/2015 indicates there was no evidence of tumor following treatment. Subsequently, in 3/2016 the patient has another penile lesion biopsy showing SCC in situ suspicious for invasion, clinically stated to be recurrent. See Discussion. |
At the central registry, we have accessioned this scenario as three primaries per Multiple Primaries/Histology (MP/H) Rule M10 (diagnosed more than 1 year apart), as the patient was stated to be disease free between each occurrence. However, the diagnosing/treating facility is not reporting these cases due to clinical statements of recurrent disease. This is an example of a case type identified on casefinding audits conducted by our central registry in which we have learned SEER's expectation of MP/H rule application does not match hospital reporting. Can the 2018 version of the MP/H rules more clearly address how this type of clinically recurrent (multiple times) case should be handled? |
Accession three tumors as the tumors were each diagnosed more than one year apart according to the MP/H Rule M10 for Other Sites. And, as you have noted, the patient was free of disease after each diagnosis. The MP/H rules have very clear instructions regarding the word "recurrence." See page 10, specifically A.7., https://seer.cancer.gov/tools/mphrules/2007_mphrules_manual_08242012.pdf SEER will evaluate the MP/H rules in the upcoming revision. |

20170042 | Reportability--Heme & Lymphoid Neoplasms: Is a diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) with large cell transformation equivalent to a diagnosis of diffuse large B-cell lymphoma (DLBCL) without mention of Richter transformation or Richter Syndrome? See Discussion. |
The patient has a history of CLL/SLL dating back to 2007, but has had progressive disease with development of a new left frontal brain tumor. The brain tumor resection proved CLL/SLL with large cell transformation, but neither the pathologist nor the managing physician called this a Richter transformation, Richter syndrome or provided a diagnosis of DLBCL. However, a large cell transformation of CLL/SLL is a Richter transformation. Can this be accessioned as a new acute neoplasm per Rule M10? |
Accession as multiple primaries according to Hematopoietic and Lymphoid Neoplasm Coding Manual Rule M10. Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) followed by CLL/SLL with large cell transformation is multiple primaries because it is a chronic neoplasm followed by an acute neoplasm, more than 21 days in this case. |

20170034 | Surgery of Primary Site--Breast: Would you code a unilateral breast simple mastectomy with tissue expanders and AlloDerm or an acellular dermal matrix as Code 45, Reconstruction with Implant, or Code 46, Reconstruction with Combined Tissue and Implant? See Discussion. |
Since acellular dermal matrix/AlloDerm comes from human tissue donors with cells removed and sterilized to promote regenesis and decrease rejection, is Alloderm coded as "Tissue' as it also "provides an additional layer of tissue between the skin and the implant? |
Assign code 43 for a simple mastectomy with tissue expanders and acellular dermal matrix/AlloDerm. The tissue expander indicates preparation for reconstruction. The acellular dermal matrix/AlloDerm is not coded because, while they often accompany an implant procedure, they are not the principle element of reconstructive procedures. The principle elements would be tissue from the patient and/or prosthetics (e.g., gel implants). |

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." |

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. |

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. |

20180101 | Histology--Kidney: What is the histology code for renal cell clear cell of the kidney with subsequent epithelioid angiomyolipoma PEComa of the liver stated to be metastatic? Case originaly diagnosed in 2016. See discussion. |
This patient was diagnosed in 2016 with renal cell clear cell and was coded to that. In 2018, the patient's liver lesion was resected and pathology revealed epithelioid angiomyolipoma perivascular epithelioid cell tumor (PEComa) (8714/3), a new term as of 2018. This was compared to the kidney slides and it was determined to be metastatic PEComa from the kidney. The physician's note states: The patient had a nephrectomy for a kidney tumor in 2016, excision of cutaneous melanomas, and resection of liver mass in 2018. These three cases were sent in consultation. The diagnosis of cutaneous melanoma was confirmed by a dermatopathologist of our department, (a separate report had been already issued). The kidney tumor is poorly differentiated composed of sheets of discohesive cells with markedly pleomorphic cells with frequent giant and bizarre cells. Most of the cells have abundant eosinophilic to clear cytoplasm. The nuclei are enlarged and pleomorphic. Multinucleated cells are numerous. Some cells have markedly enlarged nucleoli. Multifocal tumor necrosis is noted. Extensive lymphovascular invasion is observed. There are foci at the periphery of the tumor consisting of a proliferation of spindle cells with entrapped adipocytes consistent with minor element of unusual angiomyolipoma (see block A18). The liver tumor has histologic features that are similar to the poorly differentiated component of the kidney tumor. |
Revise the histology code for the 2016 diagnosis based on the review of slides performed in 2018. When new information becomes available, the information in the abstract can be updated. PEComa is a synonym for epithelioid angiomyolipoma (8860/1). These tumors can be malignant with local recurrence and or mets. For a pre-2018 diagnosis, code histology to 8860/3 using the ICD-O-3 Rule F, aka: Matrix principle. |
