20091020 | MP/H Rules/Histology--Breast: How do you code histology for a breast tumor when the comment section of the pathology report compares the current resected specimen with a previous needle biopsy? See Discussion. | A single tumor is described on the breast needle biopsy as "infiltrating lobular carcinoma and ductal carcinoma in situ" and on the lumpectomy specimen as "infiltrating duct carcinoma." Per the COMMENT section on the pathology report: "Tumor resection was compared to previous needle biopsy. The appropriate designation is probably a terminal duct/lobular lesion." | For cases diagnosed 2007 or later, assign code 8522 [Infiltrating duct and lobular carcinoma] according to Breast MP/H rule H16. The comment on the lumpectomy pathology report takes both the lumpectomy information and the biopsy information into consideration. "Probable" is an ambiguous term used to code histology. | 2009 |
|
20091041 | CS Lymph Nodes--Ovary: Are positive lymph nodes removed from "colon tissue" during a modified posterior pelvic debulking regional or distant? If regional, what is the appropriate CS LN code? |
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Pericolonic lymph nodes are "regional" lymph nodes for an ovarian primary. If you do not have enough information to assign codes 12-30, assign code 50 [Regional lymph nodes, NOS]. |

20091051 | MP/H Rules/HistologyCorpus Uteri: How should histology be coded for a "carcinosarcoma with high grade sarcomatous component within a polyp, with greater component of endometrioid carcinoma and foci papillary serous carcinoma within polyp"? | For cases diagnosed 2007 or later, assign code 8980/3 [Carcinosarcoma] according to rule H17. Rule H12 does not apply since the final diagnosis is not "adenocarcinoma." | 2009 | |
|
20091102 | MP/H Rules/Histology--Thyroid: How should histology be coded for a diagnosis of "papillary sclerosing carcinoma" with an additional description of the tumor being "nonencapsulated"? See Discussion. | Pathology report reads, "Papillary sclerosing carcinoma." In one case, the results are in CAP protocol format and next to 'Encapsulation of tumor' it says 'No.' In the other case, it is not in CAP format, but the microscopic description says, 'encapsulation of tumor - no.' Is the correct code 8350? | For cases diagnosed 2007 or later, code 8350 [Nonencapsulated sclerosing carcinoma] per MP/H Other Sites Rule H11. The definition for 8350 in the Morphology section of ICD-O-3 includes nonencapsulated as well as diffuse sclerosing papillary carcinoma. When the pathologist states 'No' for encapsulated, that means nonencapsulated. | 2009 |

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. |

20091055 | Date therapy initiated/Systemic/Surgery Sequence--Breast: How are these fields coded when a patient has chemotherapy after a sentinel lymph node biopsy and has a lumpectomy after completing chemotherapy? See Discussion. | On 4-10-08 a patient underwent sentinel lymph node biopsies. This was followed by chemotherapy which started on 4-15-08. The patient subsequently underwent a lumpectomy on 11-10-2008. | For this case, code Date Therapy Initiated to the date of the sentinel lymph node biopsy [04102008]. Assign code 3 [Systemic therapy after surgery] in Systemic/Surgery Sequence. |

20091114 | MP/H Rules/Multiple primaries--Breast: Would a left chest wall mass excision stated to be ductal carcinoma consistent with a breast primary and, "compatible with either local recurrence or potentially a metastasis" be a new primary per the MP/H rules? See Discussion. | Patient underwent mastectomy in 1986 for infiltrating ductal carcinoma of left breast. Excision of left chest wall mass in March 2009 showed ductal carcinoma consistent with breast primary. The pathology report COMMENT stated it would be compatible with either local recurrence or a metastasis. The patient's primary breast carcinoma material is not available for direct comparison and the MP/H rules instruct us to ignore metastasis. | For cases diagnosed 2007 or later, the MP/H rules do not apply to metastasis. If there is no further information available for this case, the MP/H rules do not apply to the 2009 diagnosis. | 2009 |
|
20091007 | CS Extension--Lung: How is this field coded for a tumor in the right middle lobe with extension to the bronchus intermedius? | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2. Assign CS extension code 20 [Extension from other parts of lung to main stem bronchus, NOS (EXCLUDES superficial tumor as described in code 11) Tumor involving main stem bronchus greater than or equal to 2.0 cm from carina (primary in lung or main stem bronchus)].
A right middle lobe tumor that extends to the bronchus intermedius is one that is extending to the main stem bronchus from another part of the lung. The bronchus intermedius is the lower part of the main stem bronchus on the right. It is more than 2.0 cm away from the carina. |

20091101 | CS Reg LN Pos/Exam--Melanoma: How should these fields be coded for a case that is an unknown primary site melanoma with liver involvement and a positive axillary lymph node? | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code regional lymph nodes positive 01 [one positive lymph node] and regional lymph nodes examined 01 [one lymph node examined] (assuming the positive node was the only node examined). If the only lymph node involvement is the positive axillary lymph node, it is reasonable to conclude that this is a regional lymph node. When only one chain of lymph nodes is involved with metastatic melanoma, the metastatic cells had to come from skin with direct drainage to those lymph nodes. |

20091095 | CS Site Specific Factor--Prostate: Please clarify how SEER registries should use code 040 for Site-Specific Factor 3 on prostate cases. See Discussion. | The 6/11/09 NAACCR Webinar on prostate cancer pointed out that SSF 3 code 040 refers the registrar to Note 4, which states "when the apical, distal urethral, bladder base, or bladder neck margins are involved and there is no extracapsular extension, use code 040." The webinar went on to say that code 040 ONLY applies to these specific margins, and that if other margins are involved (for example, the 'right lateral margin'), we should not use code 040. Is this consistent with SEER's interpretation of Note 4? Are we to ignore involvement of margins other than those specified in Note 4, and consequently code SSF 3 within the 000-032 range? Would this also apply to code 048 (extracapsular extension and margins involved)? | Yes, SEER agrees. Code SSF3, code 040 per page C-740 of 2007 SEER manual exactly as stated in Note 4. According to the Inquiry and Response System of the CoC, Note 4 lists specific margins that were once thought to have a prognostic impact. Code 040 in SSF3 should be used only when those margins are involved.
Note 4 pertains to code 040, not to code 048. |
