20091040 | MP/H Rules/Histology--Breast: How is histology coded for an "infiltrating papillary carcinoma" of the breast when there is no mention of ductal or adenocarcinoma in the pathology report? | For cases diagnosed 2007 or later, assign histology code 8503 [Papillary adenocarcinoma]. Rule H14 applies. ICD-O-3 code 8050 does not apply in this case. Refer to the numeric listing in ICD-O-3. 8050 is a squamous cell neoplasm. Papillary carcinoma of the breast is NOT a squamous cell neoplasm. It is a neoplasm of the breast parenchyma - ducts, lobules or connective tissue. 8503 is the correct code in this case. |

20091123 | Reportability: Is a tumor reportable if the pathology report indicates a non-reportable diagnosis at the time the specimen is removed but subsequent clinical statements state the patient had a reportable tumor? See Discussion. |
The 2007 SEER Manual (page 3) states that cases diagnosed clinically are reportable. Exception 2 states if enough time has passed that it is reasonable to assume the physician has seen the negative pathology report, but the clinician continues to call this a reportable disease, accession the case. SEER reporting guidelines state that severe dysplasia is not reportable, however, many clinicians regard it to be equivalent to carcinoma in situ. Example 1: In 09-2007 the pathology report for excisional biopsy of right floor of mouth states the final diagnosis is severe dysplasia. At the time, the case is not accessioned based on non-reportable pathology. Patient is subsequently admitted in 3-09. According to the clinical history the patient was diagnosed with squamous cell carcinoma in 2007 and treated with laser. Is this reportable? If yes, how is behavior to be coded? How is "Ambiguous Terminology at Diagnosis" to be coded? Example 2: In 2-08, the pathology report for a punch biopsy of a skin lesion states the final diagnosis is atypical melanocytic hyperplasia. In 3-08, patient is admitted for re-excision. The clinical diagnosis states re-excision being done for melanoma in situ. Reference: SINQ 20061123 |
A tumor that is non-reportable based on the pathology report diagnosis should not be accessioned if later clinician statements mistakenly refer to it as a reportable tumor. The exception in the 2007 SEER manual on page 3 is intended to allow the registrar to accession a case when the clinician actually disagrees with the pathology report and clinically diagnoses a reportable tumor. |

20091023 | Sugery of Primary Site--Breast: When a patient is simultaneously diagnosed with bilateral breast cancer and bilateral mastectomies are done, do you code the total mastectomies to 40 or 41 or 42? | Abstract cancer of the left breast and cancer of the right breast as separate primaries. Code the surgery for each primary independent of the other primary. For the first primary, assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast]. For the second primary, assign the code for the procedure performed on that site. |

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. |

20091072 | Histology--Brain and CNS: How is histology coded for a "rosette-forming glioneuronal tumor" of the fourth ventricle? | Assign histology code 9505/1 [Ganglioglioma, NOS].
Rosette-forming glioneuronal tumor of the 4th ventricle 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. |

20091084 | Primary site--Colon: How do you determine the correct subsite when there is conflicting information in different reports? Are there priority rules for coding subsite for sites other than Head and Neck? See Discussion. | The path report for a hemicolectomy says, " Specimen: left colon..." and the microscopic says, "...received in formalin designated left colon..." The Operative procedure report says, "Postoperative diagnosis - splenic flexure tumor." The text of this report says, "Mobilizing the splenic flexure mass was incredibly difficult..." and then goes on to describe exactly how and where it was resected. The discharge summary says adenosquamous carcinoma of the splenic flexure. SINQ20051010 says to use the pathology report first, but this was written before the new MP/H rules. | Use the operative report information to code primary site in this case. It is more accurate. The operative report is usually a better source of location information compared to the pathology report. The pathologist can only reiterate the location as it was reported to him/her. The 2007 SEER manual states "Unless otherwise instructed, use all available information to code the site," page 69. |

20091085 | MP/H Rules/Histology--Breast: How is histology coded for a breast primary with a final diagnosis of "infiltrating duct carcinoma with apocrine features"? See Discussion. | I & R has conflicting answers: #25719 (dated 3/17/2008) says per rule H12 this is 8401/3 but #23347 (dated 8/12/07) says per rule H16, this is 8523/3. | For cases diagnosed 2007 or later, assign histology code 8401/3 [apocrine adenocarcinoma] according to rule H12. Apocrine is a type of duct carcinoma, see table 1. Code 8401 should be listed in Rule H12. Apocrine should be removed from table 3. These corrections will appear in the revised version of the rules. |

20091090 | First course treatment--Leukemia: How should an allogeneic stem cell transplant for acute myeloid leukemia be coded in the Hematologic Transplant and Endocrine Procedures field? See Discussion. | There is debate as to whether this procedure should be coded as a 12 in order to capture the allogeneic part of the procedure. | Assign code 20 [Stem cell harvest (stem cell transplant) and infusion as first course therapy] for stem cell procedures, even allogeneic procedures. | N/A | First course treatment | 2009 |

20091094 | Reportability--Anal canal: Are squamous cell carcinomas arising in a condyloma of the rectum reportable or should we assume that the site is skin of anus or perianal area and not reportable? | Squamous cell carcinoma arising in a rectal condyloma is reportable. Do not assume the site is skin of anus or perianal. | N/A | N/A | 2009 | |

20091047 | MP/H Rules/Histology--Ovary: How is histology coded for "serous carcinoma, papillary invasive pattern"? | For cases diagnosed 2007 or later, code the histology 8441/3 [Serous carcinoma, NOS]. Use the Other Sites rules. Start with rule H8 and stop at rule H11. "Pattern" is not one of the terms used to identify a specific type (See H16), so papillary is ignored. | Ovary | Histology | 2009 |
