Primary Site--Breast: Is there a hierarchy for coding subsite for breast cases when there is conflicting information in the physical exam, mammogram, operative and pathology reports as to the exact location of the primary? See discussion.
Example: Two mammograms were performed. One report indicates the lesion is at 12:00 and the other indicates it is in the upper central quadrant. However, the pathology report from the modified radical mastectomy specimen indicates the mass is in the UIQ.
According to one of our physicians, when a pathologist has a mastectomy specimen with attached axillary contents, the location of the lesion (subsite) is very accurate.
Code the Primary Site field to C50.2 [upper inner quadrant]. In general, the priority for using information is pathologic, operative, and clinical findings. The pathology report would take precedence in this case.
The 2004 SEER Program Code manual will include the following instructions for determining breast subsite.
Priority Order for Coding Subsites
Use the information from reports in the following priority order to code a subsite when the medical record contains conflicting information:
1 Pathology report
2 Operative report
3 Physical examination
4 Mammogram, ultrasound
If the pathology proves invasive tumor in one subsite and insitu tumor in all other involved subsites, code to the subsite involved with invasive tumor.
EOD-Extension--Lung: If LUL mass "crosses the pleural surface" into the LLL, do we assume this represents extension to the pleura? See discussion.
9/22/93 Left upper lobe lobectomy: 3 x 3 cm mass in the periphery of the LUL near the LLL. Multiple enlarged nodes around the aortic arch and within the pulmonary fissure.
9/22/93 Pathology: Moderately differentiated Adenoca. The neoplasm does cross the pleural surface into the segment of the lower lobe. Lower margin of resection is free of neoplasm. Six lymph nodes negative for metastatic carcinoma. Tumor staged as T2N0M0 Stage Ib by physician.
Is tumor extension coded 10 [confined to one lung] or 40 [extension to pleura]?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 40 [extension to pleura]. The tumor has penetrated (extended to) the pleura.
Surgery of Primary Site--Cervix: How is this field coded for a cervix primary when a biopsy removes the entire tumor? See discussion.
Path from biopsy shows "severe dysplasia--CIN III" and the report from an endocervical curettage (ECC) is "chronic cervicitis"?
For cases diagnosed 1998 and later: Code the Surgery of Primary Site field to 25 [Dilatation and curettage; endocervical curettage (for in situ only)].
EOD-Extension--Lung: If a CT scan indicates that a patient has evidence of "long-standing pneumonia," is that synonymous with "pneumonitis" for the purposes of coding extension for lung primaries?
No. These terms are not synonymous. For cases diagnosed 1998-2003, disregard the pneumonia and use the other available information to code extension.
Surgery of Primary Site--Lung: What code is used to represent "photodynamic therapy" (PDT) for lung primaries? See Discussion.
PDT is not listed in the Surgery to Primary Site field codes for lung.
For cases diagnosed 2003 and later, code the Surgery of Primary Site field to 19 [Local destruction or excision, NOS] for lung primaries. Photodynamic therapy is a surgical procedure that results in the local destruction of tumor.
Grade, Differentiation--Brain and CNS: Can grade IV be implied for brain primaries with the histology of glioblastoma multiforme, even if there is no statement of grade in the path report? See discussion.
Dr. Platz has instructed the Iowa registry to code glioblastoma multiforme to grade IV, even when there is no corroborating statement of grade in the path report. This is also supported in some references.
Code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable] in the absence of a stated grade on the pathology report. If a grade is stated, code the stated grade. SEER does not recommend adopting the rule in the Discussion.
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.
Primary Site--Breast: What subsite code should be used for a diagnosis of "inflammatory carcinoma"?
Code the Primary Site field to C50.9 [Breast, NOS] for a breast primary presenting with inflammatory cancer unless there is a palpable mass within the breast. If there is a palpable mass, code the primary site to the position of the mass.
Date of Diagnosis: If a clinician states his current diagnosis of malignancy is based on a CT scan done at an early date that contained a diagnosis of only "neoplasm" or "worrisome for carcinoma" should the date of diagnosis be the date of the scan?
Yes. Code the Date of Diagnosis field to the date of the scan. The physician's clinical impression upon reviewing the earlier scan, is that the malignancy was confirmed by the scan. If there is a medical review of a previous scan that indicates the patient had a malignancy at an earlier date, then the earlier date is the date of diagnosis, i.e., the date is back-dated.
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.
