20010122 | Primary Site/EOD-Extension/EOD-Lymph Nodes--All Sites: What codes are used to represent these fields for an "extramedullary myeloid tumor (granulocytic sarcoma)" of the colon with positive or negative lymph nodes? |
For cases diagnosed 1998-2003: If only the extramedullary site is involved, such as colon, code the Primary Site field to the site of origin. Granulocytic or myeloid sarcoma is an exception to the rule that all leukemias should be coded to bone marrow as the primary site. Granulocytic sarcoma is a deposit of malignant myeloid cells in a site other than bone marrow (extramedullary). For EOD staging, granulocytic sarcoma [9930/3] is included in the Hematopoietic, Reticuloendothelial, Immunoproliferative and Myeloproliferative Neoplasms scheme and the Extension field is coded to 10 when the lymph nodes are negative, since it (like solitary plasmacytoma) is a localized deposit of tumor. However, if the regional lymph nodes associated with the extramedullary primary site are involved, code the EOD-Extension field to 80 [Systemic disease] because the disease is no longer an isolated deposit of malignant granulocytes (in other words, it is not localized). The EOD-Lymph Nodes field is coded to 9 regardless of whether or not the lymph nodes are involved because that is the only allowable code for that field. |

20010118 | All Surgical Fields/Radiation Sequence with Surgery--Unknown Primaries: What codes are used to represent these fields for an unknown primary treated with a radical neck dissection followed by radiation therapy? | For unknown primaries treated with a lymph node dissection and diagnosed 1/1/2003 and after, code: 1) Surgery to Primary Site: 98 [All unknown and ill-defined disease sites, WITH or WITHOUT surgical treatment]. 2) Scope of Regional Lymph Node Surgery: 9 [Unknown or not applicable]. 3) Surgical Procedure of Other Site: 1 [Surgery to other site(s) or node(s), NOS; unknown if regional or distant]. 4) Radiation Sequence with Surgery: 3 [Radiation after surgery]. Any planned surgical treatment is used to code radiation/surgery sequence (per CoC I&R). |

20010092 | Scope of Regional Lymph Node Surgery/EOD-Number of Regional Nodes Examined: What codes is used to represent these fields when the surgeon states that a "lymph node dissection" was done, but no nodes are identified in the pathology report? | For cases diagnosed 1/1/2003 and after: Code the Scope of Regional Lymph Node Surgery field to 3 [Number of regional lymph nodes removed unknown or not stated; regional lymph nodes removed, NOS] and code the EOD-Number of Regional Nodes Examined field to 00 [No nodes examined].
The surgery fields reflect the procedures the physician performed. The EOD fields reflect the results of those procedures. |

20010124 | First Course Treatment: What code is used to represent each treatment modality field when there is no indication that a particular modality of treatment was recommended or started? | Code the individual treatment fields to 0 or 00 [None] when the modality is not addressed in the treatment plan (or when a treatment plan is lacking) and there is no indication that a particular modality of treatment was recommended or started. | 2001 | |

20010042 | Grade, Differentiation--Bone Marrow: Can we use the AJCC Cancer Staging Manual, which lists myeloma as a B cell neoplasm under non-Hodgkin lymphomas, to code Grade, Differentiation field for myeloma to B-cell (code 6)? | For cases diagnosed prior to 1/1/2010: No. Myeloma is a malignancy of plasma cells. Plasma cells are the daughters of B cells. So technically it would be correct to call them B cell, but that is not common usage.
Cell marker (phenotype) should be coded in the Grade, Differentiation field for only leukemias and lymphomas, as classified in the ICD-O-3. In the ICD-O-3, myeloma is listed under Plasma Cell Tumors, not Lymphomas. When a cell marker is coded for a leukemia/lymphoma it should be coded only from pathology and/or cytology reports.
For cases diagnosed 2010 forward, 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. |

20010036 | Histology (Pre-2007)--Breast: What code is used to represent the histology for a single lesion with "metaplastic carcinoma" and the majority of tumor has sarcomatoid appearance? Squamous cell carcinoma and high grade intraductal carcinoma are also present. Is the term "sarcomatoid" equivalent to sarcoma? | For tumors diagnosed prior to 2007:
For cases diagnosed on or after 1/1/2001: Code the Histology field to 8575/3 [metaplastic carcinoma]. Sarcomatoid is not coded as sarcoma.
The terms metaplastic carcinoma, squamous cell carcinoma and intraductal carcinoma are used, but only the metaplastic and squamous cell carcinomas are invasive. Metaplastic, loosely defined, means tissue that is not normal.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

20010132 | Histology (Pre-2007)--Kidney: What code is used to represent the histology "renal cell carcinoma with granular cell morphology"? Kidney primary with diagnosis of renal cell CA with granular cell morphology. Do we code as granular cell carcinoma? Is the term "morphology" synonymous with "type"? See discussion. | Do we code this type of tumor as a granular cell carcinoma [8580/3]? | For tumors diagnosed prior to 2007:
Code the Histology field to 8320/3 [granular cell carcinoma]. Renal cell carcinoma is a non-specific term that has several specific cellular subtypes, one of which is granular cell [8320/3].
Note: Do not code to granular cell tumor [9580/3], which is not a histology related to renal cell carcinoma.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

20010128 | Multiple Primaries (Pre-2007)--Bladder/Prostatic Urethra: When invasive TCC of the bladder and TCC in-situ of the prostatic urethra are diagnosed at the same time, are they reportable as two primaries? See discussion. | There is no direct extension of tumor from the bladder to the urethra. According to the SEER rules for determining separate primaries, bladder (C67) and urethra (C68) are separate sites. However, it seems that TCC in the bladder and urethra should be reported as a single primary. | For tumors diagnosed prior to 2007:
This is one primary. Mucosal spread of in situ cancer from a hollow organ (bladder) into another hollow organ (prostatic urethra) is coded as a single primary.
This type of mucosal spread of tumor is sometimes referred to as "intramucosal extension" or " in situ component extending to." Mucosal spread can also be expressed as a statement of an invasive component in one organ with adjacent or associated in situ carcinoma in a contiguous organ with the same type of epithelium.
This case represents an invasive bladder tumor with in situ extension to the prostatic urethra. A tumor that is breaking down can be invasive in the center with in situ cancer at its margins. Occasionally, the in situ margin can move into a contiguous organ with the same type of epithelium.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

20010005 | Grade, Differentiation--Lymphoma/Leukemia: What code is used to represent this field for a lymph node biopsy that reveals "well differentiated lymphocytic lymphoma" and a bone marrow biopsy that reveals "chronic lymphocytic leukemia/well differentiated lymphocytic lymphoma"? | For cases diagnosed prior to 1/1/2010:
Code the Grade, Differentiation field to 1 [Grade 1] for both of these cases because there is no mention of T-cell, B-cell, null cell, or NK cell involvement. Both cases have a pathologic description of well differentiated, not the descriptors "high grade," "low grade," or "intermediate grade" which must be ignored when coding grade for lymphomas.
For lymphomas, you cannot code the descriptions "high grade," "low grade," and "intermediate grade" in the Grade, Differentiation field because these terms refer to categories in the Working Formulation and not to histologic grade. However, you can code terms such as "well differentiated", "moderately differentiated" and "poorly differentiated" for lymphoma histologies.
For cases diagnosed 2010 forward, 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. |

20010158 | EOD-Pathologic Extension--Prostate: Does capsular invasion (code 32) take priority over apex extension (code 34) on prostate primaries? See discussion. | On prostatectomy, adenocarcinoma involves left apex and also left mid lobe where it focally invades capsule. Do we code extension to 34 - the highest numerical code, or to 32 to capture the capsular invasion? Do codes 33 and 34 represent a subset of code 31, and would code 32 represent greater tumor involvement? | For cases diagnosed 1998-2003:
Code the EOD-Pathologic Extension field to 32 [Invasion into (but not beyond)prostatic capsule] when there is both capsular and apex invasion of the prostate.
Although numerically lower, code 32 takes precedence over codes 33 [arising in the apex] and 34 [extending to the apex]. Codes 33 and 34 are "subsets" of code 31 [Into prostatic apex/arising in prostatic apex]. |
