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. |

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]. |

20091045 | CS Tumor Size/CS Site Specific Factor--Breast: When tumor size is unknown, but it is known that both in situ and invasive components are present, how should CS Tumor Size and SSF6 be coded? See Discussion. | We coded CS Tumor Size 990 and SSF 6 to 060 for a case in which no tumor size was mentioned and the breast core biopsy identified microinvasive infiltrating lobular carcinoma and lobular carcinoma insitu. The lumpectomy identified no residual tumor. SEER edit 218 states we must have CS Tumor Size as 999 if the CS SSF 6 is 060. Yet the tumor size code of 990 (Microinvasion; microscopic focus or foci only, no size given; described as less than 1 mm) would more accurately reflect this case. Even in a situation where there was microinvasion described as less than 1mm, the edit will not allow one to code CS Tumor Size to 990 with the CS SSF 6 as 060. Should these types of cases have CS Tumor Size coded 999 or should the edit be adjusted to allow for this combination? | 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 CS tumor size 990 [Microinvasion; microscopic focus or foci only, no size given; described as less than 1 mm] and CS SSF6 050 [Invasive and in situ components present, size of entire tumor coded in CS Tumor Size because size of invasive component not stated AND proportions of in situ and invasive not known].
This combination of codes captures the information available for this case. |

20091018 | MP/H Rules/Multiple Primaries/CS Extension: How many primaries are to be accessioned when tumors are present bilaterally in the pleura and fallopian tubes? See Discussion. | For both pleura and fallopian tube, the MP/H rules indicate that bilateral involvement of these sites should be coded as multiple primaries. However, both of these sites have CS extension codes that classify the contralateral disease as regional extension. Is a case described as a left sided pleural mesothelioma that has right sided pleural disease coded as one or two primaries? How is CS coded? |
For cases diagnosed 2007 or later: For a pleural or fallopian tube primary, if there is tumor(s) on the left and separate tumor(s) on the right and neither is stated to be metastatic from the other, abstract as multiple primaries according to rule M8 for other sites. If both sides are involved, but there is only one tumor, rule M2 for other sites applies and this is a single primary. Code each primary separately in CS. |

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. |

20091014 | MP/H Rules/Histology--Melanoma: Please clarify what we should code when we see the term 'spitz or spitzoid' in association with melanomas. See Discussion. |
Path reports often diagnose "melanoma with spitzoid features." There is no code for this in ICD-O-3. Would it be melanoma NOS with a specific type for MP/H rule H9 (with features of...), or would we stop at H3? Could the matrix principle apply, changing 8770/0 (one of the synonyms is Spitz nevus) to 8770/3 (although no Spitz synonyms are specifically listed under this code)? What if the path report says "melanoma arising in a Spitz nevus"? |
For cases diagnosed 2007 - 2020 Assign code 8720/3 [Malignant melanoma] for melanoma with Spitzoid features, Spitzoid variant of nevoid melanoma, melanoma arising in Spitz nevus, or Spitzoid melanoma. The WHO Classification of Tumors groups these with Nevoid melanomas and codes them to 8720/3. According to WHO, "Nevoid melanoma is a subtype of malignant melanoma of the skin that is distinctive in that the primary lesion mimics many of the architectural features of a common compound or intradermal nevus ... or a Spitz nevus... These lesions are defined not as atypical nevi, but as melanomas because they involve the dermis and have the potential for metastasis." |

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.

20091107 | CS Extension--Lymphoma: Does peripheral blood involvement affect the stage for lymphoma? See Discussion. |
2009 Diagnostic Year Lymph node bx is positive for Mantle Cell lymphoma. Flow cytometry on lymph node tissue shows CD+ pos B cell lymphoproliferative disorder. IHC findings support Mantle Cell lymphoma. Flow cytometry on peripheral blood shows CD+ B cell lymphoproliferative disorder. Because the lymph node is positive for Mantle Cell lymphoma and the flow cytometry findings are the same on the lymph node tissue and peripheral blood, is the peripheral blood involved (Stage IV disease)? |
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.No. Peripheral blood is not the same as bone marrow involvement which is what would be required for stage IV. Lymphomas can arise in lymph nodes which are connected by lymphatic vessels. Both lymphatic vessels and blood vessels travel through lymph nodes and malignant cells can travel between the vessels. Cells in peripheral blood do not prove Stage IV. |

20091065 | Primary Site/CS Extension--Lymphoma: How are these fields coded for a non-Hodgkins lymphoma case with scans that show non-specific parenchymal lung nodules and a large mediastinal mass? See Discussion. |
Patient presented with large bulky mediastinal mass. CT showed no pleural effusion. Findings also show non-specific parenchymal lung nodules. Biopsy of mediastinal mass showed malignant B-cell lymphoma of follicle center cell origin. Abdomen /Pelvis CT showed borderline lymph nodes in bifurcation. Clinical diagnosis was probable stage 3 if not 4 lymphoma. Per lymphoma guidelines, if extra-nodal primary site is assigned to the extranodal site if an extra-nodal site and its regional lymph nodes are involved. Would the parenchymal lung nodules be indicative of pulmonary involvement? If so, would primary site be lung? Or, would the parenchymal nodules be stage 4 disease and primary site be assigned to lymph nodes? |
For cases diagnosed prior to 1/1/2010, 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 Primary Site to C779 [Lymph node, NOS]. In this case, there is no statement that lymphoma involves the lung. "Nonspecific parenchymal lung nodules" are not indicative of lymphoma involvement. Consequently, this cannot be assumed to be an extra-nodal lymphoma. Additionally, it is not clear whether or not the "borderline" pelvic lymph nodes are involved. If the physician cannot provide more information, follow instruction 4.e in the SEER manual on page 72. 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. |

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. |
