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.
CS Tumor Size--Breast: How is this field coded for a 1.5 cm clinically palpable tumor that appeared to be a cyst with a papilloma when the partial mastectomy Path Micro stated the lesion was an "intraductal papilloma with focal noninvasive papillary carcinoma"? See Discussion.
Should the size be coded to 999 [unknown] because the noninvasive papillary carcinoma is described only as "focal" and is not measured and it is not known how much of the tumor is benign and how much is in situ. Or would the size be coded to the size of the palpable mass, 1.5 cm?
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 CS tumor size as 999 [unknown]. Size of the focal noninvasive papillary carcinoma is not stated.
Recurrence/Multiple Primaries (Pre-2007)/Primary Site--Breast: Is a malignancy that occurs in 2005 in a mastectomy scar years following an original diagnosis of breast cancer in 1971 a recurrence (not reportable) or a new primary (breast or chest wall, NOS)? See Discussion.
The patient had a right mastectomy for breast carcinoma in 1971. In 2005, she came in with a mass in the right axilla and a right chest wall mass in the mastectomy scar. Excision of the axillary mass and biopsy of the chest wall mass revealed invasive adenocarcinoma with a similar histologic pattern. The axilla specimen contained no benign breast tissue. IHC stains exhibit strongly positive for ER, mildly positive for PR and negative for HER2/neu. The pathologist says "Although these findings are consistent with recurrent breast carcinoma, they are not specific for such. Recurrence after 34 yrs. is most unusual."
For tumors diagnosed prior to 2007:
The 2005 diagnosis is a new primary. The 1971 site differs from the 2005 site and there are more than two months between the two. Without further information, assign topography code C761 [chest wall]. The pattern of spread, including regional extension, is different for a primary of the chest wall compared to a primary in the breast. Coding the primary site to C761 will group this case with similar cases.
If further information can be obtained, look for old records that describe the extent of the 1971 mastectomy. It is possible that there was breast tissue left on the chest wall. Residual breast tissue is often present following mastectomy (simple, modified, or even radical). New carcinoma can develop in the remaining breast tissue.
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.
First Course Treatment--Unknown & ill-defined site: We have a case with an unknown primary site and the patient had chemoembolization into the hepatic artery. We don't know how to code this treatment. See Discussion.
We were told to code as surgery (10) and chemo (01). However an unknown primary automatically gets a (98) surgery code & the chemo is coded (01) but we can't code as systemic therapy. This is an edit. Chemo coded but no date of systemic therapy.
Effective for cases coded prior to the change in policy made on January 9, 2008, code chemoembolization of a metastatic site as 1 [nonprimary surgical procedure performed] in Surgical Procedure of Other Site.
Surgery of Primary Site code 98 is assigned to all cases with an unknown primary.
In the case of a liver primary, it would be coded 10 [local tumor destruction, NOS] in Surgical Procedure of Primary Site.
Date of Diagnosis--Sarcoma: Should the date of diagnosis be coded to the date of biopsy or the date of birth for an infant biopsied at 3 days of age and stated to have a diagnosis of congenital alveolar rhabdomyosarcoma, widely metastatic?
Code the date of the biopsy as the date of diagnosis. This is the date the cancer was first identified by a medical practitioner.
Note: SEER collects the Month and Year of diagnosis. The "day" of diagnosis is not collected by SEER.
CS Lymph Nodes/CS Site Specific Factor 3--Breast: How are positive intramammary lymph nodes reflected in these fields? See Discussion.
Patient with breast cancer underwent mastectomy. No axillary lymph nodes were positive, but 1 out of 2 intramammary lymph nodes were positive for mets (greater than 2 mm). CS Lymph node codes describe axillary and internal mammary nodes, but do not describe intramammary lymph nodes.
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.
Intramammary lymph nodes are coded as axillary lymph nodes for staging purposes. Intramammary node are nodes within the breast tissue. Both staging and treatment suggest these are equivalent to axillary nodes.
2004 SEER Manual Errata/Grade--Colon/Bones: Is the term "pleomorphic" used to code tumor grade to 3 for selected primaries?
Delete the row containing the word "pleomorphic" from the tables on pages 93, C-219 and C-411. This correction will be included in the next set of replacement pages for the 2004 SEER manual.
Primary Site/Priorities--Breast: When there are conflicting references to subsite in different reports, which report has priority? See Discussion.
The clinical site of the palpable mass is outer quadrant. The pathologist states inflammatory breast cancer located in the central breast. Should the site be coded to C501 for central breast, C509 for inflammatory breast ca, or C508 for outer quadrant?
Code the breast subsite from the pathology report (C501, central).
The priority order for coding subsite from conflicting reports is
1. Pathology report
2. Operative report
3. Physical examination
4. Mammogram, ultrasound
The primary site of inflammatory breast carcinoma is coded to C509 when there is no palpable tumor.
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.
