20160022 | MP/H/Histology--Breast: What MP/H Rule, histology, and behavior code for a breast primary apply to the following?
2 foci DCIS, solid, high grade (Grade 3) w/microca++ |
Apply the Multiple Primaries/Histology, Breast Rule H3: DCIS and a more specific in situ are coded to the more specific histology term which in this case is solid. Code the histology to ductal carcinoma in situ, solid type (8230/2). Based on the information provided, there is no invasive component. The term "microca ++" means micro-calcifications are present, not micro carcinoma. |

20160065 | MP/H Rules/Histology--Lung: What histology code and MP/H Rule applies to the Histologic Type described as adenocarcinoma, mixed invasive mucinous and non-mucinous which involves multiple lung tumors present in a single lobe? See Discussion. |
The patient had a lower lobectomy with final diagnosis of adenocarcinoma with the following features: Tumor Focality: Multiple separate tumor nodules in same lobe; Tumor Size: 2.6 cm, 0.7 cm, 0.3 cm and 0.1 cm in greatest dimension; Histologic Type: Adenocarcinoma, mixed invasive mucinous and non-mucinous adenocarcinoma; Histologic Grade: Moderately differentiated. |
Assign histology code 8254/3.
The 2007 MP/H Lung rules do not include coding guidelines for mixed mucinous and non-mucinous tumors. Lung Table 1 (in the Terms and Definitions, pages 37-38, http://seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf ) is very specific about which histologies can be coded to mixed adenocarcinoma (8255/3). Mucinous is not included per the note at the end of Table 1. Per WHO 3rd and 4th Ed Tumors of the Lung, mixed mucinous and non-mucinous tumors of the lung are classified as 8254/3. Mixed invasive mucinous and non-mucinous adenocarcinoma is a synonym for BAC, mucinous and non-mucinous. |

20160058 | First course treatment--Heme & Lymphoid Neoplasms: Are blood thinners, e.g., warfarin, coded as treatment in the Other Therapy data item for polycythemia vera and myelodysplastic syndrome? See Discussion. |
Under the hematopoietic data base, treatment for polycythemia vera shows chemotherapy, immunotherapy, and phlebotomy. Essential thrombocytopenia shows blood thinners, anti-clotting medications, aspirin, chemotherapy, immunotherapy, and other therapy (Anagrelide) (for essential thrombocythemia only) and watchful waiting (for asymptomatic patients). Myelodysplastic syndrome shows bone marrow transplant, chemotherapy, immunotherapy, and stem cell transplant.
SEER*RX under warfarin says: Per the 2012 Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual (page 10), blood thinners and/or anti-clotting agents are to be coded as treatment (Other Therapy) for the following histologies: 9740/4 Mast cell sarcoma 9741/3 Systemic mastocytosis 9742/3 Mast cell leukemia 9875/3 Chronic myelogenous leukemia BCR/ABL 1 positive 9950/3 Polycythemia vera 9961/3 Primary myelofibrosis 9962/3 Essential thrombocythemia 9963/3 Chronic neutrophilic leukemia 9975/3 Myelodysplastic/myeloproliferative neoplasm, unclassifiable. |
Based on information from the National Cancer Institute and the Food and Drug Administration, aspirin and/or other blood thinners are not valid treatment for polycythemia vera and myelodysplastic syndrome. These drugs are often given to relieve symptoms of the disease such as bone pain or side-effects of standard treatments including blood clots. The treatment information found on page 22 (2015 Hematopoietic & Lymphoid Neoplasms coding manual) will be updated and ICD-O-3 codes 9950/3 and 9975/3 will be removed from the list. SEER*RX has been updated to reflect this change. |

20160038 | Birthplace/Place of birth, country: For patients originally born in a country that is currently listed as "historic only", where the original birth country now has a one-to-many relationship with the current country, how should the reported original birthplace be coded? (Example: Yugoslavia) |
Assign code for Europe, NOS (ZZE) for Yugoslavia, NOS, without further information. |

20160033 | First course teatment/Surgery of Primary Site: Is microwave ablation (using heat not alcohol) coded to a surgery code? See Discussion. |
As of 2013, radiofrequency ablation is coded to "radiation therapy," chemoembolization is coded to "chemotherapy," and microwave ablation code to "other." Or, is coding microwave ablation (using heat not alcohol) coded to surgical code "16"? The latest documentation year that I could find in the SEER website regarding the above was 2013. I would appreciate clarification/confirmation of correct coding especially for microwave ablation. |
According to a consensus answer of the technical advisory group, a small group of representatives from each standard setter that meets periodically, microwave tumor ablation should be coded as surgery. For liver, assign code 16 (Heat-Radio-Frequency ablation (RFA); for kidney, assign code 15 (Thermal ablation). |

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. |

20170041 | MP/H Rules/Histology--Thyroid: How should histology be coded for a thyroidectomy final diagnosis of papillary thyroid carcinoma, favor cribriform-morula variant? See Discussion. |
This specific histology (cribriform-morula variant of papillary thyroid carcinoma) is not found in the ICD-O and is not mentioned in the 2007 MP/H Manual. However, per a web search it appears that this is a distinct type of papillary thyroid carcinoma (http://erc.endocrinology-journals.org/content/24/4/R109.full). Example: Right lobectomy shows thyroid epithelial neoplasm, pending consultation. Consultation: Thyroid gland, right lobe: papillary thyroid carcinoma, favor cribriform-morula variant. Consultation Comment: IHC stains argue against medullary carcinoma. The histologic features of growth patterns and cytologic atypia (with rare grooves and pseudoinclusions) and the immunohistochemical profile support a diagnosis of papillary thyroid carcinoma, favoring the cribriform-morula variant. It is important to note that a significant number of patients with this variant of papillary thyroid carcinoma have been associated with familial adenomatous polyposis syndrome. |
Assign code 8260/3 for papillary carcinoma of thyroid. Cribriform-morula variant is not listed in ICD-O-3 for papillary carcinoma. Multiple Primaries/Histology Rule H14 states to code papillary carcinoma of the thyroid to papillary adenocarcinoma, NOS (8260). |

20170005 | Reportability/Histology--Testis: Is neoplasm consistent with carcinoid type of monodermal teratoma reportable as a teratoma, NOS, and if yes, what is the histology code? |
Carcinoid type of monodermal teratoma or well differentiated neuroendocrine tumor (carcinoid), monodermal teratoma of the testis is reportable. Assign 8240/3 according to the WHO classification for this neoplasm. |

20170063 | Reportability/Behavior--Ovary: Is adult granulosa cell tumor a reportable malignant tumor if the primary ovarian tumor ruptured intraoperatively, the peritoneum was contaminated, and the patient underwent adjuvant treatment with chemotherapy given the increased risk of recurrence due to intraoperative tumor spill? See Discussion. |
Per SINQ 20130176 and 20140034, adult granulosa cell tumors of the ovary are reportable malignant tumors when there are peritoneal implants or metastases. The SINQ responses describe how these adult granulosa cell tumors are different from low malignant potential (LMP) epithelial ovarian tumors. Would these SINQ scenarios apply to a case with intraoperative tumor rupture that resulted in peritoneal tumor? In this case, the pathologist indicated these excised peritoneal specimens were favored to be intraoperative contamination with adult granulosa cell tumor. However, the oncologist went on to treat this patient as high risk with chemotherapy. The oncologist only described one of the pelvic peritoneal implants as possibly contamination due to the rupture. The oncologist never indicated the tumors were definitely peritoneal implants. Should the behavior of this tumor be /1 because the peritoneal tumor appears to be contamination, or /3 because the oncologist treated this patient as high risk? |
If the "implants" were due to intraoperative contamination and were not present prior to surgery, do not interpret them as indicative of malignancy. The behavior of this tumor is /1. |

20170029 | Reportability--Bone: Are giant cell tumors (GCT) of the bone that metastasize to the lung reportable? See Discussion. |
Patient had radical resection of pelvic giant cell tumor of bone in August 2012. Final diagnosis clarified that no features to suggest a frankly malignant giant cell tumor were identified. July 2013 left upper lobe nodules were removed and found to be consistent with multifocal metastatic lung involvement with a previous pelvic giant cell tumor of bone. However, the pathology report comment specifies there are no histological high-grade features to suggest a malignancy: While SINQ 20091087 may apply, these metastases clearly arrived in the lung by hematogenous spread. The previous SINQ note refers to a case where the implants/metastases can seed the surrounding pelvic and abdominal structures by rupture of the tumor or intraoperative tumor spillage. That type of spread is not quite the same as the current case showing tumor cells leaving the primary tumor/site and travelling through the blood to implant in the lungs. |
This case is not reportable. According to the WHO Classification of Bone Tumors, pulmonary metastases from GCTs are "very slow-growing and are thought to represent pulmonary implants that result from embolization of intravascular growths of GCT. Some of these benign pulmonary implants can regress spontaneously. A small number, however, exhibit progressive enlargement and can lead to the death of the patient." The pathologist for this case is very clear that no malignancy was found in the lung or in the bone. |
