20010123 | Scope of Regional Lymph Node Surgery/EOD-Lymph Node fields: How do you code these fields if a pt has multiple lymph nodes surgeries at different times? See discussion. | Example: 1/01/03 Biopsy of 1 sentinel lymph node: positive for metastasis. 1/10/03 Modified radical mastectomy and axillary lymph node dissection: ductal carcinoma with 8 neg lymph nodes. | For cases diagnosed 1/1/2003 and later: Code Scope of Reg LN Surgery to 7. Code EOD Lymph Nodes field to 6. Code EOD Pathologic Number of Reg LN Positive and Examined fields to 01 and 09 respectively.
For the Scope of Reg LN Surgery use the highest applicable code number if more than one Scope of Reg LN Surgery was performed. The EOD lymph node fields are cumulative and count all lymph nodes removed during the diagnostic and first course treatment procedures. |

20010100 | Grade, Differentiation--Lymphoma/Leukemia: What code is used to represent this field when the phenotype is combined B cell and T cell? | For cases diagnosed prior to 1/1/2010:Code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable]. There is no combination code for B cell and T cell. There is also no hierarchy established for choosing one code over the other. Therefore coding such a case as a pure B cell or a pure T cell would misrepresent the phenotype.
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. |

20010091 | Surgical Procedure of Other Site: Is the excision of a distant lymph node or a fine needle aspirate (FNA) of a distant lymph node coded as a Surgical Procedure of Other Site, even though they are performed for diagnostic purposes and not intended as treatment? | For cases diagnosed 1/1/2003 and after: Code the Surgical Procedure of Other Site field to 3 [Non-primary surgical procedure to distant lymph nodes] for an excision of a distant lymph node because it is a surgical procedure. However, if only a fine needle aspirate of a distant lymph node is done, code this field to 0 [None].
Fine needle aspirates of regional lymph nodes are the only FNA biopsies to be coded in a surgery field (Scope of Regional Lymph Node Surgery field). In addition, FNA biopsies of regional nodes are also included in the EOD-Number of Positive Regional and Examined Lymph Nodes fields. |

20010168 | Histology (Pre-2007): What code is used to represent the histology "adenocarcinoma, undifferentiated, with sarcomatoid features"? See discussion. |
Is the case more accurately coded with histology of adenosarcoma [8933/34] or adenocarcinoma, undifferentiated [8140/34]? Should "sarcomatoid" be interpreted as sarcoma? | For tumors diagnosed prior to 2007:
Code the Histology field to 8140/34 [adenocarcinoma, undifferentiated]. Sarcomatoid means sarcoma-like and should not be used in coding histology.
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. |

|
20010096 | Multiple Primaries (Pre-2007)--Bladder: Should an invasive malignancy following an in situ malignancy by more than two months be a new primary? Why? See discussion. |
Example: An in situ bladder case was diagnosed and treated. Three months later another TURB diagnosed an invasive bladder carcinoma. Is the invasive case reportable to SEER as a new primary? |
For tumors diagnosed prior to 2007: Yes. These are two primaries. In situ cancers are not included in SEER incidence rates. Incidence rates must correlate with mortality rates. 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. |

20010136 | Reason no treatment/Surgery of Primary Site: Does the "Reason for No Cancer-Directed Therapy" field only relate to the "Surgery of Primary Site" field? If so, for what diagnosis years is that effective? Have SEER's coding guidelines changed over time? See discussion. | Whenever a surgical procedure is performed that results in a non 0 or 9 code in any one of the Surgery fields, should the Reason for No Site-Specific Surgery field be coded to 0 [Cancer-directed surgery performed]? | For cases diagnosed 2003 and forward: The field "Reason for No Surgery of Primary Site" applies only to surgery of primary site. This is a change from the pre-2003 instructions. | 2001 |
|
20010148 | EOD-Extension--Lymphoma: Would a lymphoma involving mesenteric and retroperitoneal nodes (both site code C77.2) be coded to extension 10 [Involvement of a single lymph node region; Stage I], based on the fact that while more than one "chain" is involved only one "region" is involved? |
For cases diagnosed 1998-2003: Code the EOD-Extension field to 20 [Involvement of two or more lymph node regions on the same side of diaphram]. The AJCC lists mesenteric as a core nodal region, but does not list retroperitoneal lymph nodes as a part of this region, so retroperitoneal is a separate region. The EOD staging scheme for lymphoma uses lymph node REGIONS as the criteria for assigning the extension code. Use the AJCC Cancer Staging Manual as the definitive source for classifying lymph node regions, not the ICD-O-3. If it is a separate LN region per the AJCC, it is coded in the EOD as a separate region. According to the AJCC curator, the nodal regions are defined in Kaplan's book on Hodgkin disease. Bilateral cervical, or axillary, or hilar, or pelvic, or inguinal nodes count as two regions. Mediastinal and para-aortic lymph nodes count as one region regardless of laterality as they are centrally located. A large mediastinal mass constitutes one region involved regardless of the size. |

20010129 | Histology (Pre-2007)--Breast: What code is used to represent the histology "duct carcinoma, colloid type"? See discussion. | Do we use 8480/3 [colloid carcinoma] or 8523/3 [duct carcinoma] mixed with other types of carcinomas? | For tumors diagnosed prior to 2007:
Code the Histology field to 8480/3 [colloid carcinoma] per Rule 4. The lesion is colloid type of ductal carcinoma, not ductal carcinoma mixed with colloid 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. |

20010073 | EOD-Extension--Bladder: Both papillary transitional cell ca in situ and sessile (flat) transitional cell ca in situ are diagnosed simultaneously in the bladder. We code the higher histology (8130/2). For extension, do we use the code that corresponds to the histology (01), or to the higher extension code (06)? | For cases diagnosed between 1998-2003:
Code the EOD-Extension field to 06 [sessile (flat) (solid) carcinoma in situ], the higher extension code. |
