Report Question ID Question Discussion Answer (Ascending)
20031013 EOD-Extension--Pleura: How do you code this field for a pleural mesothelioma with negative pleural effusion? For cases diagnosed 1998-2003: Pleural effusion is disregarded if it is unknown, NOS or benign. Use other information on the case to stage.
20031206 EOD-Extension: How is this field coded for synchronous primaries when metastatic disease is found and there is no statement to indicate which primary is the source of the metastases? See Description. Patient was diagnosed with both esophageal and pancreatic cancer. Liver metastases were also identified. The source of the liver mets is unknown. For cases diagnosed 1998-2003: Search the record for information about the source of the metastasis. If no such information can be found, code the metastasis to both primaries. Update the abstracts when information becomes available confirming the primary site responsible for the metastasis. Assuming the liver metastases in the example above are distant (i.e. not contiguous) code extension as 85 [Metastasis].
20031087 EOD-Extension--Lymphoma/Brain and CNS: How is this field coded for a primary brain lymphoma that is described as multi-focal? For cases diagnosed 1998-2003: Since brain is the only site involved in this example, assign code 11 [Localized involvement of a single extralymphatic organ or site].
20031075 EOD-Extension--Colon: How should this field be coded for "adenocarcinoma penetrating through bowel wall into adjacent adipose tissue? For cases diagnosed 1998-2003: The difference between EOD-extension codes 40 and 45 is the level of the fat involved. Code 40 is subserosal fat immediately adjacent to the muscular wall of the colon inside the serosa/visceral peritoneum. Code 45 is pericolic fat in areas where there is a serosal surface or in the retroperitoneal areas of the ascending and descending colon where there is no serosa. Code 42 was added for use when it is not possible to determine whether subserosal fat or pericolic fat is involved. Code 42 should be used only when there is a reference to 'fat' (NOS) The answer for the case example above depends on the location of the primary and whether the fat referred to is within or outside the entire thickness of the colon wall. If no additional information is available, use code 42 [Fat, NOS].
20031141 Priorities/EOD-Lymph Nodes--Breast: Which part of the pathology report takes precedence when there is a discrepancy between the final path diagnosis and the CAP summary? See Description. For example, breast primary: Final path states "14/18 nodes (+) for tumor & separate matted aggregate of axillary nodes (+) for tumor. Subpectoral lymph node (+) for mets ca. Path Gross states "18 separate lymph nodes identified...many (+) for tumor grossly. Aggregate of matted lymph nodes within axillary tissue (+) for tumor. Multiple separate lymph nodes submitted." CAP Micro Summary lists "20/16 nodes examined/positive." What is correct number of nodes positive & nodes examined in this case? For cases diagnosed 1998-2003: The final pathology diagnosis has highest priority. The CAP summary is second priority. However, you always use the best information available. If the final path diagnosis is vague or unclear, information from the CAP summary can be used. In the case example, the total lymph node count from the final path diagnosis is unclear and the CAP summary provides clarification. Code the number of lymph nodes positive as 16 and the number examined 20. Subpectoral lymph nodes are regional nodes for breast primaries.
20031076 EOD-Size of Primary Tumor--Prostate: Is this field coded to the size of a hypoechoic mass identified on a TRUS when there is no tumor size from the prostatectomy specimen? For cases diagnosed 1998-2003: Ultrasound measurement of a malignancy can be used to code EOD-Size of Primary Tumor. Information on tumor size taken from imaging/radiographic techniques has low priority, just above physical examination.
20031006 EOD/Surgery of Primary Site--Melanoma: If a melanoma primary site is other than skin, vulva, penis, or scrotum should these fields be coded using melanoma schemes? See discussion. Should a melanoma of the cervix be coded using the melanoma or the cervix schemes for these fields? For cases diagnosed 1998-2003: Use the EOD and surgery code schemes for cervix uteri. The EOD scheme for melanoma excludes melanoma of the cervix uteri. The surgery code scheme for skin excludes cervix uteri.
20041003 EOD-Size of Tumor: How is this field coded when the only description is "greater then 10 cm?" For cases diagnosed 1998-2003: When the only information available is a statement such as "Greater than 10 cm," code tumor size 101 [10.1 cm].
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.
20000243 Surgery of Primary Site--Lung: What code is used to represent "photodynamic therapy" (PDT) for lung primaries? See Discussion. PDT is not listed in the Surgery to Primary Site field codes for lung. For cases diagnosed 2003 and later, code the Surgery of Primary Site field to 19 [Local destruction or excision, NOS] for lung primaries. Photodynamic therapy is a surgical procedure that results in the local destruction of tumor.
