Code tumor size as 100 [10 cm]. Size from pathology or operative report is preferred over size from imaging.

Code SSF6 as 050 [Invasive and in situ components present, size of entire tumor coded in CS Tumor Size because size of invasive component not stated and proportions of in situ and invasive not known.]

There is invasive tumor present (as proven by the bone metastasis), but the size and proportion of the invasive component is unknown.

Please note: Extension must be coded at least to 10 [Confined to the breast tissue and fat including nipple and areola; Localized, NOS] in this case. Do not assign extension code 00 [in situ].

We recommend that you contact the pathologist for further information. If no further information is available, do not accession this case based on the information provided. There is no definitive statement of malignancy.

If the case was sent to a consultant, there may be another opinion available. If there is information in the record, or the treating physician can be contacted, find out whether the tumor was benign or malignant and whether there was any further treatment.

According to our pathologist consultant, based only on the information above and nothing else, do not report since there is no diagnosis of malignancy.

For tumors diagnosed prior to 2007:

Assign code 8001/3 [Tumor cells, malignant] when the only information available is a cytology report stating "malignant cells."

Assign code 8000/3 [Neoplasm, malignant] when then only information available is a CT report stating "probable malignancy."

See ICD-O-3 page 27 for an explanation of "cancer" [8000] and "carcinoma" [8010].

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 Extension code is 10 [confined to cerebral hemisphere]. Record the size of the largest lesion in CS Tumor Size. Both the occipital and parietal lobes are supratentorial and confined to the cerebral hemisphere with no mention of crossing midline or involvement of ventricles.

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.

For tumors diagnosed prior to 2007:

The ICD-O-3 histology code is 8811/3 [Fibromyxosarcoma] according to the WHO Classification of Tumours of Soft Tissue and Bone. WHO defines myxoinflammatory fibroblastic sarcoma (MIFS) as "a unique low grade sarcoma with myxoid stroma, inflammatory infiltrate and virocyte-like cells that predominantly involves the hands and feet."

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.

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.

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.

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.Based on the information provided:

Code primary site C349 [Lung]. Code laterality 1 [Right]. Code CS Tumor Size 999 [Unknown]. Code CS Extension 65 [Separate tumor nodules, same lobe]. Code CS Mets at Dx 39 [Separate tumor nodule in contralateral lung].

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].
