EOD-Pathology Extension--Prostate: Is extracapsular extension implied by the phrase, "involvement of periurethral or urethral margins"? See Description.
The prostatectomy final pathology diagnosis states that the tumor involves the periurethral margin. The microscopic describes involvement of the urethral margin.
For cases diagnosed 1998-2003: Code the EOD-Extension field in the 20-34 range, which implies no extension beyond the prostate. Disregard involvement of periurethral margin or urethral margin, NOS, unless the pathologist or surgeon specifically mentions "extraprostatic urethra" involvement.
Surgery of Primary Site--Lung: Is a core-out of the main bronchus coded in this field? See Description.
Patient with right lung cancer was not a surgical candidate because of extent of disease. Prior to receiving radiation, patient underwent bronchoscopy, which revealed obstruction from right main bronchial tumor. Core-out of the tumor was undertaken, and a specimen was sent for path evaluation. The physician stated that this was a palliative procedure to relieve obstruction.
Do not code bronchoscopy to clear the airway as surgery of primary site. When combined with laser therapy, cryosurgery, or other tumor destruction, or when combined with excision of tumor, code as surgery of primary site.
For cases diagnosed 1998-2003: Code surgery of primary site for the case described above to 23 [Excision, NOS]. Tissue was excised and sent to pathology.
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.
Primary Site/Histology (Pre-2007)--Bone: How are these fields coded for a squamous cell carcinoma in bone? See Description.
The consult path report says "I believe that there is definitely high grade malignant tumor in this amputation specimen, and that this tumor represents an invasive squamous cell carcinoma, which is extending into the bone and permeating in between the bone trabeculae. ... The fact that squamous cell carcinoma can arise from the sinuses of chronic osteomyelitis is well recognized."
For tumors diagnosed prior to 2007:
Based on the information provided, code the primary site as C40._ or C41._ [bone] because the tumor originated in the sinuses of chronic osteomyelitis. Code to the site in which the tumor arises. Override the SEER site/histology edits to allow this rare combination of bone and squamous 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-Size of Primary Tumor/First Course Treatment--Breast: How is tumor size coded when preventative tamoxifen treatment precedes breast cancer diagnosis? Can we code the tumor size from the surgical specimen? Is tamoxifen treatment here? See Description.
What is the tumor size in this situation? Patient is on the STAR trial (preventative tamoxifen for women with high risk for breast cancer). Patient develops breast cancer and has surgery.
For cases diagnosed 1998-2003: Code EOD-Size of Primary Tumor from the surgical pathology report.
Do not code this preventative tamoxifen as first course cancer-directed treatment. This tamoxifen was part of a clinical trial intending to delay or prevent beast cancer from developing.
EOD-Extension--Lymphoma: How is the following guideline of "any mention of lymph nodes is considered indicative of involvement" applied for EOD-Extension of lymphoma cases when there is a discrepancy between physicians as to the stage at diagnosis? See discussion.
A biopsy of mesenteric nodes confirmed lymphoma. A bone marrow biopsy was negative. A CT of the chest indicates "small mediastinal and bilateral hilar nodes, but without convincing adenopathy." The case was Stage 2 per the oncologist and Stage 3 per the surgeon's TNM form.
For tumors diagnosed 1998-2003:
Based on the information provided for this example, the lymphoma involves one site, mesenteric nodes. Code EOD extension as 10 [Involvement of a single lymph node region].
The statement "For lymphomas, any mention of lymph nodes is indicative of involvement" refers to the terms in the paragraph above it on page 8 of the EOD manual: Palpable, enlarged, visible swelling, shotty, lymphadenopathy. While these terms are ignored for other malignancies, they should not be ignored for lymphomas. None of these terms apply to the example provided here. According to the CT, the mediastinal and hilar nodes are "small" "without convincing adenopathy." In other words, the mediastinal and hilar nodes are negative.
Reason for No Surgery of Primary Site: Does code 2 [Contraindicated due to other conditions; autopsy only case] or code 1 [ Cancer-directed surgery not recommended] have priority when coding this field for extensive tumors not surgically treated because of existing comorbidities? See discussion.
Example:
Patient has Stage IVA carcinoma of the tongue. The physician states that patient is not felt to be a good surgical candidate secondary to multiple medical frailties. Patient is treated with beam radiation.
In this case, how do we code Reason for No Site Specific Surgery? Do we use code 2 because surgery was contraindicated due to co-existing medical conditions or do we use code 1 because the tumor is very extensive and surgery would probably not be done anyway?
SEER has not established a priority for assigning the Reason for No Surgery of Primary Site codes. Assign the code which best describes the reason surgery was not performed.
Example: Assign code 2, Contraindicated due to patient risk factors. According to the physician, this is the reason that surgery was not performed.
EOD-Pathologic Extension--Prostate: Is extracapsular extension implied by the phrase "tumor invades the fibrous tissue of the capsule"? See Description.
The physician staged to a pathology stage of T3. It appears the physician regards the following pathology statement to be equivalent to capsular invasion on the right side: "Tumor invades the fibrous tissue of the capsule on the right side where it approaches to within 1 mm. of the surgical margin." Should pathologic extension be coded to 42[unilateral extracapsular extension]?
Use the best information available to stage the case. In this case, the best information is the pathologist's description of the tumor extension rather than the AJCC stage.
For cases diagnosed 1995-2003: Extracapsular extension is not implied by the phrase in the question. Code the capsular involvement described to 32 [invasion into but not beyond the prostatic capsule] on the basis of the pathology report.
Immunotherapy/Radiation Therapy: Is I-131 labeled immunoglobulin coded as immunotherapy or radiation therapy?
Code treatment with I-131 labeled immunoglobulin as radiotherapy. The primary action is radiotherapeutic. Radioimmunotherapy (RIT) uses antibodies to deliver the radiotherapy to the site of the tumor.
EOD-Lymph Nodes/EOD-Extension: Does extracapsular lymph node extension into adjacent tissue or organs affect EOD coding? See Description.
For a lung primary a PET scan showed marked uptake in the right hilum consistent with metastatic disease. A radical pneumonectomy was performed and the operative findings showed that the pulmonary artery was involved with a mass.
Pathology: Small cell carcinoma in the lung parenchyma. The distal bronchi showed obstructive pneumonitis. There were mets found on 02/05 on the hilar lymph nodes and 00/02 peribronchial nodes. The mets in the hilar nodes extended beyond the lymph node capsule into the pulmonary artery.
For cases diagnosed 1998-2003: Extracapsular lymph node extension does not affect the extent of disease. Code the extent of regional lymph node involvement in EOD lymph nodes.
