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.
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.
Surgery of Primary Site--Ovary: What code is used to represent this field when a patient has a history of a previous organ removal and has additional surgery/organ removal for a present cancer (e.g., History of a 1984 hysterectomy and in 2003 has ovarian primary treated with BSO)?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 52 [Bilateral salpingo-oophorectomy WITH hysterectomy].
Date of Diagnosis: When doing follow-back at nursing homes on DCO cases, we find it difficult to code diagnosis date because the nursing home records are often vague or incomplete. Should the diagnosis date be coded as unknown (excluded from SEER database), the date of death, or the approximate date of diagnosis as reported on the death certificate?
If the nursing home record indicates that the patient had cancer, use the best approximation for date of diagnosis.
If the record says the patient had cancer when admitted, but it does not provide a date of diagnosis, use the date of admission as the date of diagnosis.
If there is no mention of cancer in the nursing home record and/or all work-up in the record is negative, assume the cancer was discovered at autopsy. Use the date of death as the date of diagnosis, and leave as a Death Certificate Only case.
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 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.
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Colon: What codes are used to represent these fields when the pathology from a colon cancer resection describes 2/16 positive pericolonic lymph nodes and a "metastatic nodule in the pericolonic fat"?
For cases diagnosed 1998-2003:
Code the Number of Regional Lymph Nodes Positive field to 03 and the Number of Regional Lymph Nodes Examined field to 17. Each grossly detectable nodule in the pericolonic fat is counted as one regional lymph node.
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-Pathologic Extension--Prostate: If there is residual tumor in the distal urethra on prostatectomy, does that mean there is distal urethral margin involvement? See discussion.
2/98 Prostate bx: Right apex, right mid and right base positive for adenocarcinoma.
6/1/98 Radical retropubic prostatectomy w/ bilateral pelvic lymph node dissection. Pathology: Residual adenocarcinoma in distal urethra, right lateral sections and posterior lobe. Right apical margin, other margins, seminal vesicles, and 7 pelvic LN negative for malignancy.
For cases diagnosed 1998-2003:
For the example above, code the EOD-Pathologic Extension field to 34 [extending to apex] because most of the right side is involved.
The pathology report says all margins are free. The comment on residual tumor in the urethra, meant the first surgery did not completely remove tumor tissue from the urethra, it does not mean that tissue is at the margin.
