20110020 | Heme & Lymphoid Neoplasms: How is cancer status to be coded when a patient diagnosed with MDS, undergoes treatment, but the MDS subsequently transforms to AML? | If the bone marrow no longer shows evidence of MDS, the cancer status for the MDS is disease-free. When cancer status is coded as disease-free (NED), it means that currently there is no clinical evidence of this disease (MDS). | 2011 | |

20110019 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when bilateral testes are involved with lymphoma? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This is a single primary per Rule M2 which indicates to abstract a single primary when there is a single histology. Code the histology to 9590/3 [lymphoma] and the primary site to C629 [testes. Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal lymphomas occur in multiple sites, particularly in paired sites.

20110018 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted for a case with a history of follicular lymphoma, grade 2 and a subsequent splenectomy diagnosis of diffuse large B-cell lymphoma? See Discussion. |
The patient was treated over a period of time for follicular lymphoma, grade 2. The oncologist thought the spleen was congested and removed it. The diagnosis was DLBCL. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.. This case is accessioned as two primaries per Rule M10 which states to abstract multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm and there is a second diagnosis of an acute neoplasm more than 21 days after the chronic diagnosis. The first primary is follicular lymphoma, grade 2 [9691/3] and it is a chronic neoplasm. The second primary is diffuse large B-cell lymphoma (DLBCL) [9680/3] and it is an acute neoplasm.

20110017 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported if a patient originally diagnosed with CLL is subsequently diagnosed several months later on a bone marrow biopsy with Richter's syndrome that transformed into a large cell lymphoma? See Discussion. |
Per reviewed resources, the described condition is rare. Should the histology remain CLL or be changed to large cell lymphoma? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. This case is accessioned as two primaries per Rule M10 which states to abstract multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm and there is a second diagnosis of an acute neoplasm more than 21 days after the chronic diagnosis. The first primary is CLL [9823/3] and it is a chronic neoplasm. The second primary is diffuse large B-cell lymphoma (DLBCL) [9680/3] and it is an acute neoplasm. Richter syndrome (RS) is a complication of B cell chronic lymphocytic leukemia (CLL) or hairy cell leukemia (HCL) in which the leukemia changes into DLBCL. There is also a less common variant in which the CLL changes into a Hodgkin lymphoma. Richter's transformation affects about 5% of CLL patients. Richter syndrome is listed under the Alternate Names section in the Heme DB for diffuse large B-cell lymphoma [9680/3]. SEER*Educate provides training on how to use the Heme Manual and DB.

20110016 | Behavior--Brain and CNS: Can hemangioblastomas occurring in the CNS be coded as /3 (malignant) based on a radiologic or clinical diagnosis by the physician? See Discussion. | Hemangioblastomas are borderline (/1) according to ICD-O. The standard matrix rule in ICD-O directs registrars to change the behavior code to malignant when a malignant (/3) behavior is stated by a physician for a morphology code that appears in ICD-O with a non-malignant behavior code. The "malignant" hemangioblastomas we see are not pathologically confirmed; they are radiological or clinical diagnoses confirmed when renal cell carcinoma is a disease process listed in the malignant differential diagnoses. | The behavior code for hemangioblastoma can be coded to /3 when a pathologist indicates that the behavior is malignant. The behavior code should be based on a pathologist's opinion. It is usually not possible for a radiologist or patient care physician to make this determination clinically.
The histologic appearance of hemangioblastoma may resemble metastatic renal cell carcinoma; therefore, one will often see renal cell carcinoma listed as a possible diagnosis. This does not indicate that the hemangioblastoma is malignant. Do not code the behavior as /3 based on a differential diagnosis of renal cell carcinoma. |

20110015 | Primary site/Histology: Do the 4/1/09 changes in the ICD-O-3 Site/Type Validation table regarding the coding of primary site for intestinal type adenocarcinoma mean that the former valid site/histology combinations are now impossible and require review from a given diagnosis date forward? See Discussion. | Per the SEER Errata for ICD-O-3 Site/Type Validation List, April 1, 2009, adenocarcinoma, intestinal type, was removed as a valid site/histology combination for the following primary sites: C150-C155, C158-C159, C170-C173, C178-C179, C180-C189, C199, C209, C210-C212, C218. |
The site/type edit identifies unlikely combinations of primary site and histologic type. |

20110014 | MP/H Rules/Histology--Corpus Uteri: Which MP/H rule applies in coding histology for a "high grade endometrioid adenocarcinoma with squamous differentiation (adenosquamous carcinoma)"? See Discussion. | Is the pathology describing a specific histology, adenosquamous carcinoma [8560/3]? Or is this a combination/mixed histology code per rule H16? The Rule H16 instruction is to code a mixed histology code, 8323/3 [mixed cell adenocarcinoma] from Table 2 when two or more of the histologies are present (i.e., endometrioid and squamous in this case). | For cases diagnosed 2007 or later: Endometrioid adenocarcinoma with squamous differentiation is coded to 8570 [Adenocarcinoma with squamous metaplasia].
The following row needs to be added to Table 2 in order to be able to correctly use the MP/H rules to reach this conclusion.
Column 1: Endometrioid adenocarcinoma Column 2: Squamous metaplasia Squamous differentiation Column 3: Adenocarcinoma with squamous metaplasia Column 4: 8570
The change will be made in the next revision of the rules. |

20110013 | MP/H Rules/Histology--Testis: Which MP/H rule applies in coding the histology described as a "malignant mixed germ cell tumor with the following features: Histologic type: embryonal carcinoma (97%) and yolk sac tumor (3%)"? See Discussion. |
Per MP/H rule H16, code the appropriate combination/mixed code (Table 2) when there are multiple specific histologies or when there is a non-specific histology with multiple specific histologies. The combination embryonal carcinoma and yolk sac tumor is not listed in Table 2, even though the pathology report indicates this is a mixed germ cell tumor.
Should rule H17 be applied and the numerically higher histology code be used? |
As of 2016: Code histology to 9085/3 [mixed germ cell tumor]. Combine 9065 and 9085 for analysis purposes. |

20110012 | Reportability--Sarcoma: Is "atypical lipomatous tumor/well-differentiated liposarcoma" reportable? See Discussion. | The final diagnosis for a soft tissue excision is, "atypical lipomatous tumor/well-differentiated liposarcoma". The Comment section states, "Atypical lipomatous tumor/well differentiated liposarcoma has a significant risk for local recurrence, but no metastatic potential."
Per the 2010 SEER Manual, page 3, example 4: The pathologist makes the final decision about the behavior for a particular case. In this case, the pathologist uses both a reportable and a non-reportable term in the final diagnosis and in the comment section of the pathology report. Does the pathologist's comment impact the behavior and reportability of this tumor? |
For cases diagnosed 1/1/2014 and later: Atypical lipomatous tumor (8850/1) is not reportable. If the pathologist uses the term "well-differentiated liposarcoma" (8851/3) report the case. Use of this terminology indicates a less favorable prognosis. | 2011 |

20110011 | Reportability--Heme & Lymphoid Neoplasms: Is a 2010 diagnosis of "thrombocytopenia of unknown etiology" reportable? See Discussion. | No exact match returned after entering the term "thrombocytopenia of unknown etiology" in the Heme DB. However, the program does indicate there are 17 results that could be displayed that show any of the 4 terms entered. Clicking on the search label indicates there are no matches either.
The only result returned after entering "thrombocytopenia" into the search box is "refractory thrombocytopenia." |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
"Thrombocytopenia of unknown etiology" is not reportable. Thrombocytopenia refers to a low platelet count which causes bleeding. Thrombocytopenia can be caused by viral infections, excessive alcohol usage, HIV, and other causes (including chemotherapy). If the diagnosis is not "refractory thrombocytopenia" the case is not reportable. Appendix F lists this term as non-reportable.
If you do not see the term in the Heme DB under either the Name column or the Alternative Names section for the results returned, it is not reportable. The only reportable term that contains the word thrombocytopenia is refractory thrombocytopenia. Therefore, thrombocytopenia of unknown etiology is not reportable.
