Reportability/Behavior--Thymus: Are "lymphocyte predominant thymoma with microscopic capsule invasion" and "Polygonal epithelial cell thymoma with invasion of the lung and pericardial fat" reportable?
Please see SINQ 20110038 for the most recent information on reporting thymoma.
Surgery of Primary Site--Skin: What surgery code is used to reflect the amputation of a finger for subungual melanoma?
47 [Wide excision or reexcision of lesion or minor (local) amputation with margins greater than 2cm] is the correct surgery code for amputation of a finger for melanoma.
Grade, Differentiation--Bladder: If the only indication of grade for a bladder primary is "grade 2, NOS," and we do not know the grading system being used by the pathologist, is the numeric grade 2 coded?
See the General Coding Rules on page 92 of the 2004 SEER Manual for instructions about coding grade.
If the only information available is "Grade 2," assign code 2 [Grade II].
Date of Diagnosis--Bladder: Should the date of diagnosis be based on the 1/7/04 urine cytology with low grade transitional cell carcinoma or the subsequent 1/27/04 pathology findings of papillary transitional cell carcinoma?
In this case, the date of the cytology is the date of diagnosis, 01-07-2004.
CS Eval--All Sites: If any of the CS fields (TS/Extension, LN, or Mets) are based on the TNM and there is no text documenting the basis for the evaluation, are the evaluation fields coded to 0 instead of 1?
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 code 0 [No surgical resection done...based on physical exam...or other non-invasive clinical evidence] to the corresponding eval fields when CS Extension, Lymph Nodes or Mets at Diagnosis are coded based only on the TNM and no further information is available.
Reportability/Behavior--Brain and CNS: How is a brain "neoplasm" diagnosed only by CT scan reported to SEER? See Discussion.
We have a significant number of patients who come into our emergency room and are diagnosed with a brain neoplasm by CT scan. They are transferred to another facility for further care. Some of those facilities will give us information - histology, treatment, etc. Some will not. How are we supposed to report these brain neoplasms if we don't know if they are benign or malignant? Can we report them as behavior code 9 or do we just report them as benign if we can't get any further information?
The case above is reportable and 8000/1 is the most appropriate histology/behavior code. A clinical diagnosis alone from diagnostic imaging reporting a brain 'neoplasm' (with a diagnosis date supporting the reportable case requirements) even with no other information available (from biopsy or resection) is reportable. Care should be taken when reviewing terms used by the radiologist on these reports, since some tumors exhibit defining characteristics that can be picked up on diagnostic imaging.
CS Site Specific Factor--Melanoma: What is the correct code for measured thickness in SSF 1 for a melanoma of the choroid without an enucleation? See Discussion.
CS Site Specific Factor 1 for melanoma of the choroid codes "Measured Thickness (Depth), Breslow's Measurement." The note for this field states "Record actual measurement in millimeters from the pathology report." For melanoma of the eye, there is often only an eye exam report stating the thickness. Can PE thickness (clinical statement only) be coded for SSF 1 or is this field coded only from pathology? (i.e., all cases treated without enucleation would have this field coded to 999)
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 SSF 1 999 [Unknown] when there is no enucleation, and therefore, no pathology report for a choroid melanoma.
Date Therapy Initiated/Reason no treatment--Lymphoma: Is the date of the lymph node biopsy used as the date of treatment if the lymph node biopsy is the first treatment or the only treatment performed? Is the reason for no surgery coded to 0 [Surgery of the primary site was performed]?
For cases diagnosed prior to January 1, 2008, enter the date of the lymph node biopsy (excisional biopsy or biopsy NOS) as the Date Therapy Initiated for a lymphoma when the biopsy is the first or only therapy performed.
Code Reason for No Surgery of Primary Site as 0 [Surgery of the primary site was performed] and the biopsy of a lymph node is coded to 25 in Surgery to Primary Site.
Do not code a fine needle aspiration or core needle biopsy in Surgery of Primary Site.
Reportability--Brain and CNS: Does a case of astrogliosis meet the criteria for gliomatosis cerebri? See Discussion.
Case clinically stated to be a glioma of the brain. Pathology from resection states astrogliosis.
Anderson's Pathology defines astrogliosis as astrocytic proliferations. Gliomatosis cerebri is defined as diffuse neoplastic transformation of poorly differentiated astrocytes over a wide area; predominantly invovles hemispheric white matter.
The pathologic diagnosis for this case, astrogliosis, is not reportable to SEER. Take the definitive diagnosis for this case from the pathology report from the resection. The pathology report takes precendence over the clinical diagnosis.
