20091031 | MP/H Rules/Histology--Thyroid: How is histology coded for a thyroid tumor described as "predominantly papillary carcinoma, tall cell variant, follicular type"? | For cases diagnosed 2007 or later, assign code 8340 [Papillary carcinoma, follicular variant] according to rule H15 for Other Sites. "Predominantly" and "type" indicate specific histologies. "Variant" does not. See rule H13. The histology in this case is papillary and follicular. Tall cell variant is ignored. |

20091068 | Primary site--Bladder: What is the appropriate subsite for "adjacent to the bladder neck"? | Assign code C679 [Bladder, NOS]. It is not possible to determine the location of the tumor from the description. A tumor that is "adjacent to bladder neck" could be located in the trigone or on the bladder wall (anterior, posterior or lateral). | 2009 | |
|
20091092 | MP/H Rules/Histology--Lung: How should Diagnosis Date, Diagnostic Confirmation and Histology be coded for the LEFT lung mass in the following case? PET shows a 3 cm mass in the left lung and a 2.9 cm mass in the right lung. No reportable terminology in PET. The right mass is biopsied and shows adenocarcinoma. The left mass is not biopsied. Based on rule M6, this should be reported as two primaries. No additional information in medical record. Patient expired. |
For cases diagnosed 2007 or later: For date of diagnosis, use the date of the PET scan for both primaries. For the left tumor, assign diagnostic confirmation code 8 [Clinical diagnosis only] and assign histology code 8000/3 [malignant neoplasm]. The left lung mass is reported as a separate primary because there is one tumor in each lung. According to Rule M6, when there is one tumor in the left lung and one tumor in the right lung, each tumor is a separate primary. Tumor and mass are equivalent terms for purposes of the multiple primary rules. |

20091010 | MP/H Rules/Histology--Breast: What histology is coded when a final diagnosis on a lumpectomy specimen states "adenocarcinoma" but the regional lymph nodes show "poorly differentiated adenocarcinoma with signet ring differentiation"? See Discussion. | 3/23 left breast mass bx: infiltrating lobular carcinoma. 6/22 left breast lumpectomy: infiltrating adenocarcinoma; sentinel lymph nodes with metastatic poorly differentiated adenocarcinoma with signet ring differentiation. Axillary resection with poorly differentiated metastasis in 8/9 nodes. The path micro states: tissue consists of sections of breast tissue having an infiltrating ca which in some areas infiltrates as small duct-like structures, and in other areas as small gland-like structures. In addition, there are foci in which the cells infiltrate in a single file fashion. In a few areas, cells having a signet ring appearance similar to those seen in the lymph nodes are encountered. In other areas, the signet ring appearance is not prominent. Areas of ductal or lobular ca in situ are not identified (the lymph node resection specimen shows 'signet ring appearance in some areas but no ductlike or tubular structures observed')
The comment on the lumpectomy path states: 'This is an unusual tumor in that it has histologic characteristics in varying areas, which would be consistent with infiltrating ductal carcinoma, infiltrating lobular carcinoma, tubular carcinoma or signet ring cell carcinoma. The metastatic material (8/9 total axillary lymph nodes) is most consistent with the poorly differentiated signet ring type portion of the tumor undergoing metastasis.' |
For cases diagnosed 2007 or later: Code the histology 8140 [Adenocarcinoma, NOS] using Breast rule H14. Code the histology from the final diagnosis on the pathology report of the most representative specimen (the lumpectomy in this case). Do not code histology from the microscopic description. Code the histology from the primary site whenever available, not the metastatic site.
Comments on pathology reports can be used to code histology. However, in this case the final diagnosis is more definitive than the comments. The comment provides several choices and none of these appear in the final diagnosis; an indication that the pathologist was not able to clearly identify a more specific type in this case. |

20091130 | MP/H Rules/Histology--Breast: What is the correct histology code and MP/H rule used for 1) infiltrating ductal carcinoma, mucinous type and 2) infiltrating ductal carcinoma with features of tubular carcinoma? See Discussion. |
There is confusion as to which rule applies. Should the histologies be coded to 8480/3 [mucinous adenocarcinoma] and 8211/3 [tubular adenocarcinoma] respectively per rule H12? Rule H12 states to code the most specific histologic term; "type" and "with features of" are used in the pathologic diagnosis and are both terms that can be used to code the specific histology. Or would the histology be coded 8523 for both examples per rule H17 because neither histologic codes 8480/3 or 8211/3 are included as examples of duct carcinomas, nor are they included in Table 2? |
For cases diagnosed 2007 or later, code 8523 [infiltrating duct mixed with other types of carcinoma] for
1. Infiltrating ductal carcinoma, mucinous type and 2. Infiltrating ductal carcinoma with features of tubular carcinoma
The infiltrating ductal types in Rule H12 are listed (8022, 8035, 8501-8508) and do not include mucinous or tubular. We cannot use this rule. The first rule that applies to these single tumors is H17, code to 8523. If you look up 8523 in the numerical morphology section of ICD-O-3, you will see similar examples included in the definition of this code. |

20091105 | Multiple Primaries--Hematopoietic: How many primaries and which histologies should be reported for a case presenting with a 2005 diagnosis of CLL/SLL, 2006 clinical diagnosis of MDS and a 2008 diagnosis of AML? See Discussion. |
2005 diagnosis of CLL/SLL (9670) with lymph node involvement, treated with FCR. 2006 clinical diagnosis of MDS secondary to chemo (9987) with CLL/SLL in remission. 2008 biopsy reveals AML (9861). Per Seer Hematopoietic Table, 9987 & 9861 are a single primary. In 6/2008 patient receives bone marrow transplant. 2009 status post BMT, BM biopsy reveals RAEB-1 (9983). Is this still the same disease process or a new primary (since status post BMT)? |
For cases diagnosed prior to 1/1/2010:Two primaries should be abstracted. Using the Definitions of Single and Subsequent Primaries for Hematologic Malignancies table, compare 9670 (SLL) in 2005 and 9987 (MDS secondary to chemo) in 2006. This is two primaries. MDS can transform to AML. On the Definitions of Single and Subsequent Primaries for Hematologic Malignancies table, 9987 (MDS) and 9861 (AML) are a single primary. The AML would be documented in follow-up. (While 9670/SLL and 9861/AML are two different primaries, the SLL has already been reported.) RAEB is a form of MDS. On the Definitions of Single and Subsequent Primaries for Hematologic Malignancies table, 9987 (MDS) and 9983 (RAEB) are a single primary. The RAEB would be documented in follow-up. (While 9670/SLL and 9983/RAEB are two different primaries, the SLL has already been reported.) For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20091088 | MP/H Rules/Histology--Breast: How is histology coded for a diagnosis of "metaplastic carcinoma with the sarcomatous component of high grade sarcoma with focal areas of osteoid formation"? See Discussion. | Right breast simple mastectomy, path: 2.5 x 1.5 x 1.5 cm metaplastic carcinoma with; the sarcomatous component is high grade sarcoma with focal areas of osteoid formation. The epithelial component is predominantly grade 2 DCIS. | For cases diagnosed 2007 or later, assign code 8575 [Metaplastic carcinoma, NOS]. Metaplastic carcinomas often include mixtures of epithelial carcinoma with sarcoma, for example. | 2009 |
|
20091093 | Race--How and when is Appendix D, Race and Nationality Descriptions from the 2000 Census and Bureau of Vital Statistics, to be used? See Discussion. |
For example, if race is recorded as unknown on the facesheet of a hardcopy medical record or in the race field of an electronic medical record, how should race be coded for the following descriptions found in the history and physical or consultation reports submitted by clinicians? 1) Patient is Czechoslovakian 2) Patient is born in Czechoslovakia 3) Patient is Ethiopian 4) Patient is born in Ethiopia 5) Patient is Japanese 6) Patient is born in Japan 7) Patient is Brazilian 8) Patient is born in Brazil Would you code these cases any differently if these descriptions were actually used in the race fields in the medical record or on a death certificate? |
Code the patient's stated race when possible. Refer to Appendix D, Race and Nationality Descriptions from the 2000 Census and Bureau of Vital Statistics, for guidance. Use the lists in Appendix D when race is not stated but other information is provided in the medical record. The cases you provide are good examples of the use of Appendix D. They would be coded the same if the descriptions were used in the medical record or death certificate race fields. |

20091037 | MP/H Rules/Histology--Brain: How is histology coded for a "low grade neuroglial tumor" of the fourth ventricle? | For cases diagnosed 2007 or later, assign histology code 9505/1 [Ganglioglioma, NOS].
According to our pathologist consultant, low grade neuroglial tumor of the fourth ventricle correlates best to the "rosette-forming glioneuronal tumor of the 4th ventricle" which is a new WHO entity. There is no current ICD-O-3 code for this. The best code available at this time is 9505/1. |

20091006 | Primary site--Lung: What primary site code is used for bronchus intermedius? |
Assign code C340 [main bronchus].
The bronchus intermedius is the lower part of the main bronchus on the right side. The bronchus intermedius begins just below the point where the upper lobe bronchus branches off from the main bronchus. The bronchus intermedius branches into the middle lobe bronchus and the lower lobe bronchus.
