EOD-Extension/SEER Summary Stage 2000--Kidney/Eye: What codes are used to represent these fields for simultaneous bilateral Wilms tumor or simultaneous bilateral retinoblastoma?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 85 [Metastasis] and the SEER Summary Stage 2000 field to 7 [Distant] for both types of tumor. Each kidney and each eye are staged separately in the AJCC, 6th ed., but for SEER we would abstract these diagnoses as one case and code the EOD and stage fields to distant to reflect the involvement of both eyes or both kidneys.
Histology (Pre-2007)--Colon: What code is used to represent histology when the surgeon describes a sessile polyp and the final path diagnosis is stated as: "Rectal sessile polyp: Invasive moderately differentiated adenocarcinoma" (pathologist does not state that it is "arising in a sessile polyp")?
For tumors diagnosed prior to 2007:
Code the Histology field to 8210/3 [adenocarcinoma arising in a polyp]. The structure in which this adenocarcinoma is arising, is a polyp.
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.
Date of Diagnosis--All Sites: Is it better to estimate the month in the date of diagnosis field using the re-excision pathology report date or code the month to unknown if the only available information is the re-excision date? See discussion.
The only available information is the following pathology report:
On 7/18/00 a wide excision of the primary lesion is done. The report reads, "Lesion approximately 1 cm. Residual superficial spreading malignant melanoma with deepest penetration 4 mm."
Code the Date of Diagnosis field to 07/2000 for this case. Estimate the month of diagnosis whenever possible.
Given the usual delay between the initial excision of the lesion and a wide excision for a melanoma, estimate the month of diagnosis as July.
EOD-Clinical Extension--Prostate: For prostate cancer, can an elevated PSA be used to code metastasis? See discussion.
5/31/98 PE: 30 gm prostate with nodularity, suspicious for CA.
Final diagnosis: Stage D Ca of prostate with mets, NOS
PTA IVP: Normal collecting system
5/11/98 CXR: NED
PSA 86.3 Suggestive of prostate Ca per MD
5/13/98 TURP and bilat. orchiectomy: Plan was to perform orchiectomy as treatment of choice if biopsy was positive. Appears MD feels that the patient has mets, NOS based on the elevated PSA.
5/13/98 TURP Adenocarcinoma, PD
For cases diagnosed 1998-2003, do not code the EOD-Clinical Extension field based on elevated PSA alone. If a recognized practitioner states that there is metastasis, then metastasis should be coded.
In this case, code the EOD-Clinical Extension field to 85 [Metastasis] because it is Stage D. But if you had D1 or D2 staging based on the involvement of lymph nodes, then that involvement would be coded under EOD lymph nodes and not under the clinical extension field.
EOD Fields--All Sites: Is EOD information limited to what is available exactly two months from the day of diagnosis?
For cases diagnosed 1998-2003:
EOD should include all information available within four months of diagnosis in the absence of disease progression or through completion of surgery(ies) in first course of treatment, whichever is longer.
Mets known to have developed after EOD was established should be excluded.
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.
EOD-Extension--Cervix: Should this field be coded to 11 [minimal microscopic stromal invasion] or 12 [microinvasion] when there is only a statement of "microinvasion" but no measurements describing the level of involvement given?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 12 [microinvasion] when there are no depth of invasion measurements given.
Code the EOD-Extension field to 11 [minimal microscopic stromal invasion] when there is a statement of "minimal STROMAL invasion."
Surgery of Primary Site/Date Therapy Initiated--Cervix: Should "negative endocervical curettings" be coded as surgical treatment for carcinoma in situ of the cervix primaries and should the date of the procedure ever be used in coding the Date Therapy Initiated field?
For cases diagnosed 1/1/2003 and later: Code Surgery of Primary Site to 25 [D&C endocervical curettage (for in situ only)]. If this is the first treatment given, the Date Therapy Initiated is coded to the date of the curettage.
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].
Extension/Ambiguous terminology: How should the terms "entrapped by tumor" and "encased by tumor" be interpreted when coding these fields?
Each case must be reviewed in its entirety to determine the appropriate coding of these fields. However, in general the terms "entrapped" and "encased" should NOT be interpreted as involvement unless there is other clinical or pathologic evidence to support involvement.
