20130156 | Other therapy--Heme and Lymphoid Neoplasms: Based on the hematopoietic manual instructions, is plasmapheresis coded as treatment for Waldenstrom macroglobulinemia? See Discussion. | A patient, who was diagnosed with Waldenstrom macroglobulinemia at another facility, presented to our facility for plasmapheresis on 12/27/2012. No other treatment was given.
How is the plasmapheresis coded for treatment? |
Do not code plasmapheresis as treatment. It does not modify the neoplasm. | 2013 |

20210027 | Reportability--Heme and Lympoid Neoplasms--Polycythemia vera: Is secondary polycythemia vera reportable? See Discussion. |
A physician stated the patient likely had secondary polycythemia vera due to cardiac and pulmonary conditions but that a polycythemia vera could not be ruled out. A JAK2 was ordered that was positive for JAK2 V617F mutation. The patient was treated with hydrea. According to SEER SINQ 20120049, secondary polycythemia vera is not reportable. However, in this case, the patient was positive for JAK2 V617F mutation. Therefore, is this reportable? We looked for guidance in the Hematopoietic and Lymphoid Neoplasms Database and found it confusing that secondary polycythemia vera was not mentioned or discussed under polycythemia vera in the database. The only thing we could find was secondary polycythemia NOS that was discussed under polycythemia. |
Abstract as a new primary for polycythemia vera, 9950/3. JAK2 is commonly used to assess suspected polycythemia vera and in this case, the mutation is positive for V617F. Based on the JAK2 results, this looks like a true polycythemia vera and not a secondary polycythemia. |

20180112 | Solid Tumor Rules (2018)/Histology--Lung: What is the histology code of a non-small cell lung cancer (NSCLC), NOS as this is not on the AJCC list of histologies? See Discussion. |
A question was posted to CAnswer forum 9/26/18 and answered stating that 8046 is not on the AJCC list of histologies for the lung chapter in the 8th edition. If the final diagnosis on the pathology report is just NSCLC, NOS with no subtype/variant, what histology/solid tumor rule would I use? In this situation, I am not able to query the pathologist. Would I code the histology to 8010 as per AJCC post? |
Code NSCLC to 8046/3. Do not change a histology code simply to assign TNM to the case. AJCC does not determine histology coding. While pathologists are no longer encouraged to use NSCLC, it does not mean the term and code are obsolete. NSCLC could be any number of histologies such as adenocarcinoma or squamous carcinoma. A diagnosis of NSCLC indicates that the initial exam of the tissue did not identify a more specific type of NSCLC. Additional immunohistochemical testing is needed to determine the histology. Update the case if better information becomes available from subsequent tests/review. When analyzing the data, researchers and physicians will be able to identify the cases where the pathologist was unable to or did not perform further testing to determine a specific histology which drives treatment and survival. |

20180102 | Solid Tumor Rules 2018/Histology--Brain and CNS: What code should be used for high grade neuroepithelial tumor with BCOR Alteration? See Discussion |
A recent molecular study of PNET tumors at NCI (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5139621) seems to indicate the discovery of four new CNS tumor entities, of which HGNET-BCOR is one. The article suggests that these are not primitive neuroectodermal tumors tumors (PNET), but something different. |
This question was reviewed by an expert neuropathologist. He recommends coding these tumors to malignant tumor, clear cell type 8005/3. He states: these tumors are extremely rare. In summary, CNS HGNET-BCOR represents a rare tumor occurring in young patients with dismal prognosis. Whether CNS HGNET-BCOR should be classified among the category of "embryonal tumors" or within the category of "mesenchymal, nonmeningothelial tumors" remains to be clarified. Because CNS HGNET-BCOR share pathologic features and characteristic BCOR-ITD with clear cell sarcoma of the kidney, these tumors may represent local variants of the same entity. |

20160061 | Reportability/Behavior--Small intestine: Is a carcinoid tumor, described as benign, reportable? See Discussion.
|
A segmental resection pathology report states "benign mucosal endocrine proliferation consistent with a 0.3 cm duodenal carcinoid tumor." The diagnosis comment further states, "the separate small endocrine lesion is histologically benign, consistent with a 3 mm carcinoid tumor." This seems to be an example of a description of a microcarcinoid tumor referenced in SINQ 20160011. However, in this new case the pathologist specifically states the tumor is benign.
The WHO definition of microcarcinoid indicates this is a precursor lesion, which seems to indicate it is not malignant. However, SEER's previous answer stated we should report these tumors because the ICD-O-3 definition of carcinoid is 8240/3. Do you think that the mention of the term "benign" in the pathology report is actually related to the size of this lesion? Is the reference to benign mucosal endocrine proliferation referring to the WHO classification (making the case reportable as stated in SINQ 20160011), or is this a situation in which we should apply the Matrix Rule and the case is nonreportable? |
This carcinoid tumor, described as benign, is not reportable. According to our expert pathologist consultant, this case is not reportable because the pathologist uses "benign" to describe the mucosal endocrine proliferation and based on that, the neuroendocrine cell proliferation is hyperplasia/benign - not reportable. |

20010094 | Reportability/Ambiguous Terminology--Breast: Should the American College of Radiology (ACR) BI-RADS assessment categories 4 [Suspicious Abnormality--biopsy should be considered] and 5 [Highly Suggestive of malignancy-appropriate action should be taken], impressions for mammograms and sonograms, be used as the sole basis for reportability? See discussion. |
ACR website: Category 4: Lesions that do not have the characteristic morphologies of breast cancer but have a definite probability of being malignant. Category 5: lesions have a high probability of being cancer. |

20170055 | First Course of Treatment/Surgery of Primary Site--Corpus uteri: Do you code total hysterectomy or radical hysterectomy when a specimen indicates the uterus, cervix, ovaries, fallopian tubes, and right and left parametrium were resected, but shows no portion of the vagina. See Discussion. |
AFS1-AFS2-frozen section control, endomyometrium; AFS3-frozen section control, subserosal intramural mass; A4-anterior cervix; A5-posterior cervix; A6-anterior cervical endometrial junction; A7-posterior cervical endometrial junction; A8-A10-anterior endomyometrium, including tumor; A11-A13-posterior endomyometrium, including tumor and adjacent mass; A14-random section subserosal mass; A15-left parametrium at margin of resection; A16-right parametrium at margin of resection; A17-A18-left ovary and fallopian tube; A19-A20-right ovary and fallopian tube. The final diagnosis includes Endometrial adenocarcinoma, favor serous carcinoma, with papillary and solid areas. Tumor involves: Cervix present, Right ovary, Left ovary, Right fallopian tube, Left fallopian tube, Right parametrium, Left parametrium. |
Assign code 50 for total hysterectomy. According to Appendix C Surgery Codes for Corpus Uteri of the 2016 SEER Coding and Staging Manual, total hysterectomy is surgery to remove the entire uterus, including the cervix; whereas, radical hysterectomy includes the vagina. |

20150037 | Reportablility--Breast: Is lobular neoplasia reportable as lobular carcinoma in situ? See Discussion. |
According to College of American Pathologists (CAP), lobular neoplasia is also known as lobular carcinoma in situ. In a previous SEER question 20041089, it was stated that they were not the same and should not be reported unless it was a Grade 3. I assume this has changed and we are to report lobular neoplasia as lobular carcinoma in situ, is this correct? |
For cases diagnosed 2021 or later Lobular neoplasia (LN II and LN III) and lobular intraepithelial neoplasia (LIN II and LIN III) are reportable and coded 8520/2. |

20021042 | Hormone Therapy--Breast: Should Zoladex (gosrelin) or Lupron (leuprolide acetate) be coded as treatment for breast cancer when the physician does not indicate whether or not these drugs are intended as cancer-directed therapy? See discussion. |
According to an oncologist at the research hospital in our region, these drugs are given in combination with chemotherapy for two reasons:
1) To preserve ovarian function. 2) The agents may be more effective in treating breast cancer when given in conjunction with chemotherapy than with chemotherapy alone. |
For cases diagnosed 1/1/2003 to 12/31/2010: Code Zoladex (gosrelin) and Lupron (leuprolide acetate) as 01 [Hormone therapy administered as first course therapy] only when stated to be given as part of the first course of cancer-directed therapy. If you do not know whether these drugs were given to preserve ovarian function or as an adjunct to chemotherapy (i.e, there is no treatment plan), do not code as Hormonal treatment given. |

20091021 | Behavior/Reportability--All sites: Would a GIST tumor stated to be "high risk for malignant behavior" be a reportable GIST? See Discussion. |
According to our pathologist and oncologist, the terms "malignant" and "benign" do not apply to GIST. Rather, the term "high risk for malignant behavior" is used. This is based on tumor size: greater than 5 cm and mitotic activity: greater than 5 mitoses/50 hpf. |
Do not report the case to SEER if it does not satisfy the criteria for reportability. According to the current reportability criteria, malignant GIST (8936/3) is reportable to SEER. GIST coded to 8936/0 or 8936/1 is not reportable. If your pathologist will not indicate "malignant" or "benign," code 8936/1 applies according to ICD-O-3 and, therefore, these are not reportable to SEER. |
