CS Extension--Bladder: How should this field be coded when the pathology states "papillary transitional cell carcinoma with no invasion into the submucosa or deep muscularis" but there is "focal extension of tumor into bladder diverticula"?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Code the CS Extension field to 01 [Papillary transitional cell carcinoma stated to be noninvasive]. Extension into bladder diverticula does not change the code. Diverticula are pouches in the mucosa (mucous membrane).
Reportability/Date of Diagnosis--Ovary: Is a patient SEER reportable in 2001 or 2003 if she presented with a diagnosis of papillary serous tumor of low malignant potential [borderline tumor] per the 5/2001 surgery but at the time of the planned second look laparoscopic surgery is stated to have Stage 3A ovarian cancer? See Discussion.
A patient was seen in 5/2001 for large pelvic mass growing from right ovary. After TAH and USO and partial omemtectomy, path diagnosis was papillary serous tumor of low malignant potential (borderline tumor), unruptured. Right ovary and omental implant have identical histologic appearance, except the psammoma body formation and the ovary does not.
Patient does not return for lap as planned in 6-12 months.
In 1/03 she returns to hospital with abdominal pain and has debulking, hemicolectomy and Hartmann's procedure. 1/03 Path report "metastatic papillary serous adenoca." Chart now says "History of stage 3A ovarian cancer."
Yes, this case is reportable in 2003. Malignancy was confirmed in 2003. The diagnosis made in 2001 is not reportable for that year, and was not reviewed or revised according to the information provided.
Primary Site/Histology (Pre-2007)--Mediastinum: How do we code these fields for a case described as a "neuroendocrine carcinoma" of the "anterior mediastinum" without failing the SEER "impossible" site/histology combination edit? See Discussion.
Two different facilities state that the patient has "neuroendocrine carcinoma of the anterior mediastinum." This coded combination failed SEER edit (SEERIF38). We can not correct it because that edit flag does not appear on our system. Both facilities indicate that the mediastinum is the primary. In addition, there is text to support both the histology and primary site codes.
For tumors diagnosed prior to 2007:
The combination of C381 [anterior mediastinum] and 8246 [neuroendocrine carcinoma] will be removed from the list of "impossible" site/histology combinations. There are rare cases of neuroendocrine carcinoma of the anterior mediastinum. As illustrated in the discussion, verify that the primary site is anterior mediastinum, the histology is neuroendocrine ca, and document those findings in the text.
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.
CS Tumor Size--Breast: How is this field coded when a core needle biopsy removes the majority of the tumor? See Discussion.
Rule 4.j on page 128 of the 2004 SEER Manual states "Do not code the tumor size from a needle biopsy unless no residual tumor is found on further resection".
Example: 3/04/04 core biopsy Rt breast grade 1 infiltrating ductal carcinoma tumor size 0.8cm. 3/10/04 Lumpectomy: 3mm focus of residual infiltrating ductal carcinoma. If we can not take the size of the core needle biopsy, do we use the residual size of 3mm or the clinical size which was 1cm on mammogram?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Code the tumor size from the mammogram. Do not code the tumor size from the needle biopsy because residual tumor was present in the lumpectomy specimen.
CS Extension/EOD Extension--Renal Pelvis: Primary site is renal pelvis with direct extension to the rt adrenal gland. What is the correct extension code?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Assign CS Extension code 67 [Adrenal gland from renal pelvis] for adrenal extension from renal pelvis -- T4 and regional direct extension.
CS Site Specific Factor 4--Prostate: If PAP is not mentioned in the chart, should Site Specific Factor 4 be coded to 999 [unknown or no information] or 000 [test not done]?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.For tumors diagnosed 2004 only:
Code the CS Site Specific Factor 4 to 999 [Unknown or no information; Not documented in patient record]. If there is no report of a lab test in the health record, code as 999.
Code this field to 000 [Test not done] when there is a statement in the record that a test was not performed.
Tumors diagnosed 1/1/2005 forward no longer have PAP coded in the Site Specific Factor 4 field.
Primary Site--Head & Neck: How is this field coded for a tongue primary described as "located on the lateral" or "left oral" tongue? See Discussion.
Case 1. Patient with squamous cell carcinoma, left oral tongue.
Case 2. Squamous cell carcinoma, left lateral tongue.
Case 3. Patient status post biopsy of lesion on tongue. Exam: healing left lateral tongue incision with sutures in place in underside of tongue.
Code Primary Site for cases 1 and 2 above to C023 [Anterior 2/3 of tongue, NOS]. Code lateral tongue without mention of dorsal or ventral surface to C023 [Anterior 2/3 of tongue, NOS].
Code Primary Site for case 3 to C022 [Ventral surface of tongue]. The underside of the tongue is specified as the site of the biopsy in case 3.
EOD-Extension--Breast: If the pathology report states "infiltrating duct carcinoma...measuring 7mm in diameter...focal areas of intraductal carcinoma," do we code this field to 14 [Invasive and in situ components present, size of entire tumor coded in Tumor Size and in situ described as minimal] or to 16 [Invasive and in situ components present, size of entire tumor coded in Tumor Size and proportions of in situ and invasive not known]?
For cases diagnosed 1998-2003: If 7mm is the measurement of the infiltrating duct portion of this cancer, assign extension code 13 [Invasive and in situ components present, size of invasive component stated and coded in Tumor Size].
If 7mm is the size of the whole malignancy and the size of the invasive portion cannot be determined, assign extension code 14 [Invasive and in situ components present, size of entire tumor coded in Tumor Size (size of invasive component not stated) and in situ described as minimal (less than 25%)]. "Focal areas of in situ carcinoma" qualifies as minimal.
