Primary Site--Esophagus: What is the difference between C15.5 [Lower third of esophagus] and C15.2 [Abdominal esophagus]?
These descriptions represent the use of two different ways the esophagus can be divided anatomically. The two different systems used are illustrated in the SEER Self Instruction Manual for Tumor Registrars: Book 4. Assign the primary site code that describes the location of the tumor in the same way the tumor's location is described in the medical record.
Place of Birth: When there is conflicting information, which record takes precedence in coding this field, the medical record or the death certificate?
If there is a discrepancy, use the information from the medical record to code the Place of Birth field. The information from the medical record is provided by the patient, the information on the death certificate is provided by others. If the medical record does not contain birth information, use the information from the death certificate.
Primary Site: What site code is used to classify a femur biopsy with pathologic diagnosis of "Ewing sarcoma/primitive neuroectodermal tumor (PNET)"? See discussion.
ICD-O-3 lists PNET as being site specific to C71._. The pathology report states "some authors consider both Ewing sarcoma and PNET to be the same histologic entity given that they share the same translocation between chromosomes 11 and 23."
Code the Primary Site field to C40.2 [femur] based on Rule H in the ICD-O-3 that states, "Use the topography code provided when a topographic site is not listed in the diagnosis. This topography code should be disregarded if the tumor is known to arise at another site."
Histology (Pre-2007)--Colon: What code is used to represent the histology "adenocarcinoma arising in a papillary adenomatous polyp"? See discussion.
Is "adenocarcinoma arising in a papillary adenomatous polyp" equivalent to adenocarcinoma in a villous adenoma [8261/3] or adenocarcinoma in an adenomatous polyp [8210/3]?
For tumors diagnosed prior to 2007:
Code the Histology field to 8261/3 [adenocarcinoma in a villous adenoma]. In describing colon polyps, papillary and villous are equivalent terms.
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.
Surgery of Primary Site/Reconstruction-First Course--Breast: If the plan is to "reconstruct" the breast 6 months after an ipsilateral modified radical mastectomy, is the time span a problem or should it be coded in the Surgery of Primary Site field because it was planned?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 55 [Modified radical mastectomy WITHOUT removal of uninvolved contralateral breast, Implant]. The time span is not a problem as long as the reconstruction was planned as first course, which is indicated by tissue expander insertion at the time of the original surgery.
EOD-Pathologic Extension--Prostate: Can a pathological extension code be assigned when a retropubic prostatectomy is done? See discussion.
The TNM manual states, "Total prostatoseminalvesiculectomy and pelvic lymph node dissection are required for pathologic staging."
For cases diagnosed 1998-2003:
The pathology report from a retropubic prostatectomy should be used to code the Pathologic Extension field. This field is coded using pathology report information from the prostatectomy operation regardless of the surgical approach and regardless of whether or not a pelvic lymph node dissection was performed. This is one area in which TNM rules for pathologic staging and SEER rules for EOD are slightly different.
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.
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: How do you distinguish between clinical extension codes of 10, 13, 14, and 20 for cases with a benign prostate per digital rectal exam that appear localized after TURP/prostatectomy? Can the clinical extension code of 10 be used if the term "microscopic carcinoma" is noted in the pathology report without also mentioning "foci" or "Stage A" for clinically inapparent tumors?
For cases diagnosed 1998-2003:
When the prostate feels benign and the cancer is found incidentally at the time of the microscopic exam, code the EOD-Extension field to 10 [number of foci or % of involved tissue not specified]. Code as 13 (less than or equal to 5%) or 14 (greater than 5%) if percentage involved is given in the tissue resected. If the path report states "solitary focus of carcinoma" without mentioning the total amount of tissue resected, code extension to 13. If there is more than one focus, code extension to 10. Don't assign a code of 20 unless the tumor is clinically apparent.
