Place of Birth: When there is conflicting information, which record takes precedence in coding this field, the medical record or the death certificate?
If there is a discrepancy, use the information from the medical record to code the Place of Birth field. The information from the medical record is provided by the patient, the information on the death certificate is provided by others. If the medical record does not contain birth information, use the information from the death certificate.
EOD-Pathologic Extension--Prostate: Can a pathological extension code be assigned when a retropubic prostatectomy is done? See discussion.
The TNM manual states, "Total prostatoseminalvesiculectomy and pelvic lymph node dissection are required for pathologic staging."
For cases diagnosed 1998-2003:
The pathology report from a retropubic prostatectomy should be used to code the Pathologic Extension field. This field is coded using pathology report information from the prostatectomy operation regardless of the surgical approach and regardless of whether or not a pelvic lymph node dissection was performed. This is one area in which TNM rules for pathologic staging and SEER rules for EOD are slightly different.
EOD-Extension: General instructions, page 7, note 3 states: " Extent of disease information obtained after treatment with neoadjuvant chemotherapy, hormone or immunotherapy has begun may be included." Because the SEER manual does not mention radiation treatment, can we use information from a lobectomy to code EOD if a patient has neoadjuvant radiation therapy?
Radiation therapy was inadvertently omitted from the list. Please see SINQ 20031012 answer as to when the surgical information can be used to stage the case.
EOD-Extension/EOD-Lymph Nodes--Kaposi Sarcoma: What code is used to represent this field for a Kaposi sarcoma with no skin lesions but positive lymph node and bone marrow biopsies?
Code the EOD-Extension field to 13 [Visceral (e.g., pulmonary, gastrointestinal tract, spleen, other)], because of the positive bone marrow. Code the EOD-Lymph Nodes field to 3 [Both clinically enlarged palpable lymph nodes (adenopathy) and pathologically positive lymph nodes], for the pathologically positive node.
Note: Potential revision of the extension scheme will be referred to SEER Medical Advisory Group (SMAG).
EOD-Extension--Mycosis Fungoides: Explain the difference between extension codes 25 [% of body surface not stated, no tumors] and 30 [skin involvement, NOS; extent not stated, no tumors. Localized, NOS]?
For cases diagnosed 1998-2003:
For mycosis fungoides: Use code 25 when skin involvement is present but only a general location/site is mentioned (i.e., face, legs, torso, arms).
Use code 30 when there is skin involvement but there is no mention of location/site.
EOD-Extension--Small Intestine: How do we interpret a pathology description of "extending through serosa and forming masses in the periserosal tissue" for a jejunum primary?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 55 [Invasion of/through serosa and adjacent connective tissue]. The description states the tumor extended through the serosa into periserosal tissue. The periserosal tissue in this case refers to adjacent connective tissue lying exterior to the intestinal wall and not the (sub)serosal tissue that lies exterior to the muscularis but inferior to the serosa. Analyze each case individually since pathologists are not consistent when using the above terminology.
EOD-Extension/EOD-Lymph Nodes--Bladder: Are "perivesical nodules" coded in the EOD-Lymph Nodes field or are they discontinuous extension and coded in the EOD-Extension field?
For cases diagnosed 1998-2003:
Code "perivesical nodules" in the EOD-Lymph Nodes field as involvement of regional lymph nodes. Each gross nodule of metastatic carcinoma in the fat surrounding an organ is counted as one positive regional lymph node.
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined/Surgical Procedure of Other Site--Kaposi Sarcoma: How do you code these fields for a groin mass excision containing 4 lymph nodes for a Kaposi sarcoma case that presented with multiple skin lesions?
Code the EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined fields to 99 99 for Kaposi cases that present systemically and for those that present in more than one site (which includes cases with more than one skin subsite involved at diagnosis). There are no "regional" lymph nodes for such cases. This represents a majority of currently diagnosed Kaposi cases. However, for localized Kaposi cases, you can count the number of regional lymph nodes positive and examined if the primary site selected has a regional lymph node chain(s) associated with it (e.g., soft palate, hard palate, or a skin subsite).
For cases diagnosed 1/1/2003 and after: Code the groin mass excision in the Surgical Procedure of Other Site field to 1 [Non-primary surgical procedure performed; Non-primary surgical resection to other site(s), unknown if whether the site(s) is regional or distant].
EOD-Extension--Stomach: What code is used to represent this field for a stomach primary described as linitis plastica?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 30 [Localized, NOS], unless more information is known about the extent of tumor involvement. Coding the Histology field to 8142/3 [Linitis plastica] and the Size of Primary Tumor field to 998 [Diffuse; widespread; 3/4 or more: Linitis plastica] identifies this diagnosis.
In the EOD-Extension field, the depth of invasion is the important characteristic to be coded. The 10 digit EOD corresponds to the AJCC Staging Manual in which the "T" is based on level of invasion. While a diagnosis of linitis plastica indicates a worse prognosis, it does not define the extent of infiltration. There is no luminal mass with linitis plastica. Instead, the entire gastric wall is thickened by tumor.
EOD-Lymph Nodes/TNM--Breast: Do we code these lymph nodes fields for a breast primary that describes ipsilateral axillary lymph node involvement as "extending through the lymph node capsule and into perinodal soft tissue/fat" as "fixed/matted"?
For cases diagnosed 1998-2003:
Code the EOD-Lymph Nodes field to 6 [Axillary regional lymph nodes, NOS], if the size of the metastasis within the lymph node is not known. "Extension into perinodal soft tissue" does not imply that the lymph nodes are fixed to one another or to other structures. AJCC stage for lymph nodes is coded to N1 [Metastasis to moveable ipsilateral axillary lymph nodes].
In order to code the EOD-Lymph Nodes field to 5 [Fixed/matted ipsilateral axillary nodes] which is the equivalent to AJCC equivalent N2, there must be some clinical or pathologic statement of fixation or matting. There can be extension through the capsule without fixation or matting. "Fixation" is a clinical term and "matting" can be either clinical or pathologic. A pathologist can recognize two or more lymph nodes stuck together by tumor.
