EOD-Clinical Extension--Prostate: How is this field coded when biopsies of the prostatic apex are positive and the physician clinically stages the case as T1c?
For cases diagnosed 1998-2003:
Code clinical extension to 33 [arising in the prostatic apex] when a biopsy of the prostatic apex is positive for malignancy, with no further evidence of involvement. If biopsies of both the apex and another site within the prostate (for example right lobe) are positive and there is no mention that the malignancy arose in the apex, code extension to 34 [extending into the prostatic apex].
Tumor Markers--Breast: If the ERA/PRA results reported differ for separate breast specimens removed for a single primary, do we code the results as positive or negative?
For cases diagnosed 1998-2003:
Code both the Tumor Marker 1 and Tumor Marker 2 fields to 1 [positive] when a single primary breast tumor has both positive and negative ERA/PRA receptors.
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--Head & Neck (Tonsil): How should the EOD-Extension field be coded for bilateral tonsil involvement? See discussion.
Tonsillectomy and bilateral radical neck dissections were done. The path diagnosis was left and right tonsils: squamous cell carcinoma, bilateral tonsils with negative inked surgical margins of resection. Physical exam and operative findings did not mention any extension beyond the tonsils.
We originally coded the EOD-Extension field to 30 for a bilateral tonsil primary. The case failed the SEER Edit IF41 (Primary Site/Lat/EOD). According to that edit, if laterality is 4 then the EOD-Extension field must not be 00 through 30.
We recoded the EOD-Extension field to 99 in order to comply with the SEER edit.
For cases diagnosed 1998-2003:
Code EOD extension as 30 [Localized, NOS] and laterality as 4 [Bilateral involvement]. The next update to the SEER edits will allow this combination.
EOD-Size of Primary Tumor: 1) Can we add "Imaging studies" to those EOD schemes that currently do not include this on their priority list for coding size? 2) When an EOD scheme already lists specific types of imaging studies, are we limited to only those types of procedures or can any imaging study be used to code size? See discussion.
How do we determine where to add "imaging studies" to the priority listing? Currently the hierarchy differs for primaries that currently include imaging studies on their EOD schemes. For example, on the breast EOD imaging ranks lower than the physical exam while on the thyroid EOD imaging ranks higher than the physical exam.
For cases diagnosed 1998-2003:
1) You may add "Imaging" to the size priority list for all EOD schemes that currently do not include it. Prioritize it just above the physical exam for these sites.
2) You may use the information from any imaging technique to code tumor size, even for those sites such as breast and bladder where specific imaging tests are mentioned.
EOD-Size of Primary Tumor--Prostate: If you only have a biopsy and not a resection of the primary site, can you code the size of the prostate nodule demonstrated on digital rectal exam? See discussion.
Example 1: Digital rectal exam reveals 1 cm left side prostate nodule. TRUS-guided biopsy of left side of prostate shows adenocarcinoma. Right side biopsy is negative. Is size coded to 010 or 999?
Example 2: Digital rectal exam reveals 1 cm left side prostate nodule. Bone scan was positive for metastatic disease. Is size coded to 010 or 999?
For cases diagnosed 1998-2003:
You need path confirmation that a malignancy exists in the prostate before you can code the size of the nodule seen clinically.
Example 1: Code the EOD-Size of Primary Tumor to 010 [1 cm], because the nodule in the prostate is confirmed as cancer by needle biopsy.
Example 2: Code the EOD-Size of Primary Tumor to 999 because there was no pathologic confirmation of malignancy.
EOD-Extension/EOD-Lymph Nodes: Can the AJCC TNM/Stage be used to help code these fields when there is limited text information in the medical record that describes the tumor involvement?
For cases diagnosed 1998-2003:
Yes, this staging information can be used to help code the SEER EOD fields but only if a physician does the TNM/Stage at the time of diagnosis and there is limited text information that describes tumor involvement.
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: What codes are used to represent these fields when only a regional lymph node (positive) aspiration is performed?
For cases diagnosed 1998-2003:
With the exception of those sites/histologies that require 99 in these fields, code the Number of Regional Lymph Nodes Positive field to 97 [Positive nodes but number of positive nodes not specified]. Code the Number of Regional Lymph nodes Examined field to 95 [No regional Lymph nodes removed, but aspiration of regional Lymph nodes was performed].
EOD-Lymph Nodes/Extension: How does one code these fields if the clinical level of disease extension prior to neoadjuvant treatment is greater than demonstrated on pathology at time of resection? See discussion.
Breast case described clinically as a "breast mass and nodal metastases" which is treated with neoadjuvant chemotherapy and at surgery the lymph nodes are pathologically negative.
For cases diagnosed 1998-2003:
Use the combination of clinical and pathologic information to code EOD for primary site, extension and lymph nodes. Code the more extensive disease. If lymph nodes are positive clinically and not positive after neoadjuvant treatment, code lymph node involvement. If lymph nodes are negative clinically and positive on path, code lymph node involvement. When neoadjuvant treatment is administered because of a clinical statement of stage or involvement, code EOD based on this clinical information, even if later pathologic information would lead to a lesser EOD. General guideline number 6 (page 1 of SEER EOD-88 3rd ed.) points out that clinical information must be considered when coding EOD. However, do not code EOD based on clinical information disproved by pathologic findings in the absence of intervening treatment. The scenario above: The clinical involvement of the nodes justifies the neoadjuvant chemotherapy. Therefore, code EOD based on the clinical lymph node involvement.
EOD-Extension/EOD-Lymph Nodes--Rectosigmoid: How do you code these fields for a scan-based clinically staged T3 N1 rectosigmoid primary in a patient who received chemotherapy and radiation prior to a resection that demonstrated invasion only into the muscularis and no positive lymph nodes?
For cases diagnosed 1998-2003:
Use the best information available, in this case, the clinical staging, to code EOD. Code the EOD-Extension field to 40 [Invasion through muscularis propria or muscularis, NOS] and the EOD Lymph Node field to 3 [Regional lymph node(s) NOS] because the case had a clinical stage of T3 N1. EOD is coded using the most extensive clinical or pathologic stage.
