20091069 | CS Extension--Bladder: How should this field be coded for a high grade urothelial carcinoma with "focal micropapillary features and invasion of lamina propria, with a note stating there is invasive carcinoma focally involving thin muscle bundles...difficult to distinguish whether muscularis propria or muscularis mucosae"? | 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 15 [Invasive tumor confined to subepithelial connective tissue (tunica propria, lamina propria, submucosa, stroma)]. The information provided confirms invasion of the lamina propria (code 15) but is not definitive enough to assign a code higher than 15. |

20091059 | CS Tumor Size--Breast: How is this field coded for DCIS that is present in scattered small foci over five of eight slides, and the greatest aggregate dimension measures 0.5 cm? See Discussion. | Breast biopsy was prompted by abnormality seen on mammography. Would this be an example of when to code 996 (mammographic/xerographic diagnosis only, no size given; clinically not palpable) applies for the CS Tumor Size field? | 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 code 005 [0.5 cm] in this case. According to the General Instructions for CS tumor size, it is acceptable to code an aggregate size stated by the pathologist (see instruction 4.i). |

20091122 | MP/H Rules/Multiple primaries-Brain: Does a glioblastoma multiforme following a low grade glioma (oligodendroglioma) represent a new primary? See Discussion. | In 2/08 patient underwent resection of tumor of right frontal lobe. Path diagnosis showed a low grade glioma, favor low grade oligodendroglioma (WHO grade II). In 02/09 biopsy of a left thalamic mass showed glioblastoma mutiforme. Per rule M6 glioblastoma multiforme following a glial tumor is a single primary. Per path diagnosis, the first tumor represented a low grade glioma. However, oligodendroglioma is not on the glial branch of chart 1 in the MP/H rules. |
For cases diagnosed 2007 or later, glioblastoma multiforme following oligodendroglioma are multiple primaries according to rule M8. Rule M6 does not apply. M6 applies only to glial tumors as listed in chart 1. Chart 1 is based on the WHO classification. The WHO classification separates oligodendroglial tumors from glial tumors. | 2009 |

20091063 | CS Lymph Nodes--Head and Neck: How is this field coded when a positive neck FNA is followed by a neck dissection that contains one of seventeen positive lymph nodes? See Discussion. | The primary site is the right tongue. The patient underwent FNA of a right neck mass that was positive for squamous cell carcinoma. Subsequent right modified radical neck dissection showed one out of seventeen nodes positive for metastatic carcinoma. For head and neck primaries, the CS LN codes 10-19 represent a single positive ipsilateral regional node. Codes 20-29 represent multiple positive ipsilateral nodes. | 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.If the neck dissection included the area of the positive FNA, count only the positive nodes from the dissection. Avoid double-counting a positive node for both an FNA and a dissection. In the unlikely event that the dissection did not include the area of the positive FNA, add one positive node to the count from the dissection. This instruction supersedes previous instructions. |

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 |

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. |

20091073 | Grade: Can FIGO grade be used to code Grade/Differentiation? See Discussion. | SINQ 20020059 says not to use FIGO grade to code differentiation. It also says SEER is evaluating whether the ICD-O-3 sixth digit differentiation codes accurately represent the FIGO grade. For the time being, do not code FIGO grade. What is the result of the evaluation? Any new information regarding FIGO grade? | 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.Do not code FIGO grade in the grade field. The conversion from a three-grade system to a four-grade system does not work for FIGO grade three. Since FIGO G3 includes both Poorly differentiated and undifferentiated, it cannot be converted. FIGO grade may be captured in a CS site specific factor in the future. |

20091046 | CS Lymph Nodes/CS Site Specific Factor--Melanoma: When CS Lymph Nodes is coded 13, 14 or 15 (codes used when satellite nodule(s) or in-transit metastases are present), why must CS SSF 3 be coded 000 (No lymph node metastasis)? See Discussion. | 3/11/05 Consult - PE: huge exophytic lesion right lower leg (mushroom-type lesion), 6cm. Below that lesion is another ulcerative lesion 2cm. Right upper arm lesion w/ satellite nodule. Note from physician states malignant melanoma on right lower leg metastatic to the left arm/shoulder. No scans done so there is no assessment of the lymph nodes. We coded CS LNS to 13, which captures the satellite nodule, CS SSF3 = 999 and CS Reg Nodes Eval = 0. SEER Edit 216 requires the SSF3 to be 000. SSF 3 is coded 999 as there is no information about the clinical status of lymph nodes. |
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.When CS lymph nodes is coded 13-15, SSF 3 must be coded 000. Follow the instruction in the SSF 3 Note: Use code 000, No lymph node metastases, if ... there are satellite nodules or in-transit metastases, but no regional lymph node metastases, i.e., CS Lymph Nodes is coded 13-15.
For this case, assign CS lymph node code 15 [Satellite nodule(s) or in-transit metastases greater than 2cm from primary tumor WITHOUT regional lymph node involvement or involvement of regional nodes not stated]. The arm lesion is more than 2cm from the leg lesion. |

20091104 | MP/H Rules/Histology--Esophagus: How is histology coded for a biopsy of the esophagus with a pathologic diagnosis of "adenocarcinoma, intestinal type" when there is no evidence of a gastric tumor in scans or EDG? See Discussion. | There is a rule for colon to disregard "intestinal type" and code to adenocarcinoma (8140) but no rule for esophagus. How should histology for this esophageal case be coded? | For cases diagnosed 2007 or later: Follow MP/H Other Sites Rule H11 and code 8144/3 [Adenocarcinoma, intestinal type]. Adenocarcinoma, intestinal type, is called that because it resembles the normal pattern of adenocarcinoma seen in the large intestines. It is not an indication of the location of the adenocarcinoma. We find that it is not uncommon in the sinuses, stomach, lungs, cervix, and many other organs. |

20091128 | MP/H Rules/Multiple primaries--Breast: How many primaries are to be accessioned when a patient was diagnosed with breast carcinoma in 2001 and was subsequently diagnosed with a mammary carcinoma in a chest wall mass in 2008? See Discussion. |
Patient was diagnosed with invasive lobular carcinoma of the right breast in April 2001. Following modified radical mastectomy in May 2001, the patient was disease free. In December 2008 the patient was diagnosed with a right chest wall mass, invasive poorly differentiated mammary carcinoma with lobular origin. If this is a new primary in 2008, would we code the primary site to breast or chest wall? Please see I&R answers 25924, 22163 and 26155 with similar case scenarios that give two different answers. One response indicates coding this type of scenario as new primary to chest wall and the other two responses indicate this should not be a new primary because the chest wall is a metastatic site. The pathology report does not state that this is metastatic and it is unknown if there is breast tissue left behind at the chest wall. |
For cases diagnosed 2007 or later, this case is a single primary. The chest wall (NOS) is a metastatic site for breast cancer. There is no mention of residual breast tissue, so the 2008 diagnosis cannot be a new primary. "Chest wall" is an ambiguous term. It can mean the internal chest wall or the external chest wall. When the path report states that the "recurrence" is in residual breast tissue, this is most likely the external chest wall and the residual breast tissue is part of the breast not removed by the MRM. In contrast, skin or the chest wall, NOS, are regional metastases. |
