EOD-Extension--Ovary: What code is used to represent this field for an ovarian primary presenting with "spread to the omentum"?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 75 [Peritoneal implants, NOS] because the size of the implants on the omentum is not known.
Note 6 was added to the EOD scheme which states that both direct extension and discontinuous metastasis to the omentum are coded in the range 70-75 depending on how the peritoneal implants are described.
Ambiguous Terminology: Should SEER's lists of ambiguous terminology be modified to reflect how pathologists and radiologists actually use these terms? See discussion.
Pathologists and radiologists say the term "suggestive" is used to describe a lesion that may be malignant, and the term "suspicious" is not used to describe lesions that may be malignant. According to the physician director of our Breast Center the FDA governs the use of terminology, and the term "highly suggestive" instead of "highly suspicious" must be used if there is a greater chance that a mass is malignant.
We recognize that the way clinicians and registrars speak is often different, and that the differences vary from region to region.
Our Medical Advisory Board reviewed the lists of ambiguous terminology before they were included in the third edition of the SEER EOD and the SEER Program Coding and Staging Manual 2004. Since that time, specific terminology has been mandated for describing mammography results. We know some of these terms are discrepant with our ambiguous terminology list.
As of 2007, the standard setters (CoC, NPCR, SEER and CCCR) all use the same ambiguous terminology list. Changes to the list must be approved by the NAACCR Uniform Data Standards Committee.
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.
EOD-Lymph Nodes--Lung: What code is used to represent this field when the only information is a description of:
1. "hilar mass"
2. "mediastinal mass"
3. "enlarged" or "greater than 1 cm" used to describe any of the lymph nodes listed under code 2 in the EOD Lymph Nodes field?
For cases diagnosed 1998-2003:
Code EOD-Lymph Nodes fields as follows for the examples given:
1) 9 [Unknown; not stated] for a "hilar mass"
2) 2 [Mediastinal] for a "mediastinal mass"
3) 2 [Mediastinal] for "enlarged" or "greater than 1 cm," if used to describe any of the named lymph nodes listed under code 2 in the EOD-Lymph Nodes field.
EOD-Extension--Corpus Uteri: What code is used to represent this field for a corpus primary (sounding 8 cm or less in length) treated with radiation prior to a hysterectomy that pathologically showed superficial myometrial invasion? Is it possible that the invasion could have been more extensive prior to the radiation treatment?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 12 [Myometrium, inner half] which represents the extension you know. In this particular case, there was no clinical evidence of extension outside the corpus. As long as the surgery was not performed because of disease progression, use information from the surgery to code EOD extension.
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.
Histology (Pre-2007): What code is used to represent the histology for a "malignant invasive gastrointestinal stromal tumor (GIST)"?
For tumors diagnosed 2001-2006: Malignant GIST is coded 8936/3.
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.
Histology (Pre-2007): What code is used to represent the histology "non-small cell carcinoma, NOS"? See discussion.
Should a non-small cell carcinoma histology be assumed to be a large cell carcinoma [8031/3] or should the histology be coded to carcinoma, NOS [8010/3]?
For tumor diagnosed 2001-2006: Code the Histology field to 8046/3 [non-small 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.
EOD-Extension--Corpus Uteri: How do you code myometrial involvement described as 1) "to the level of the middle one-third" or 2) "superficial"?
For cases diagnosed 1998-2003:
Evaluate each case carefully.
1. Code the EOD-Extension field to 12 [Myometrium-inner half] because the pathology report indicates involvement of the myometrium "to the level of." However, if you feel that you cannot make that determination with certainty and you cannot ask a pathologist for clarification, then code the EOD-Extension field to 14 [Myometrium, NOS].
2. Code the EOD-Extension field to 12 [Myometrium-inner half] for cases with "superficial" myometrial invasion.
EOD-Extension--Lung: Should the phrase "some pleural fluid in both posterior gutters" be interpreted as pleural effusion for lung primaries? See discussion.
CT scan: "3 cm mass left upper lobe of lung. Some pleural fluid in both posterior gutters. Large matted hilar lymph nodes, left. Some narrowing left upper bronchus by this adenopathy. Squamous cell ca lung with mets to left hilar lymph nodes, most likely possibility." Would you code extension to 72 [malignant pleural effusion; pleural effusion, NOS]?
For cases diagnosed 1998-2003:
Yes. Code the EOD-Extension field to 72 [malignant pleural effusion, pleural effusion, NOS]. Pleural effusion is mentioned as being present.
