Question:

EOD-Size of Primary Tumor/EOD-Extension--Breast: How do you code extension when the tumor in the breast is in situ and the regional axillary lymph nodes are positive? See discussion.

Discussion:

For example, what extension code is used for a 4.5 cm DCIS (no invasive ca found in excisional biopsy or mastectomy specimen) with mets to 01/07 LNs?

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Size of Primary Tumor field to 045 [4.5 cm]. Document how the size was determined in the EOD-Extension field.

Code the EOD-Extension field to 16 [Invasive and in situ components present, size of entire tumor coded in Tumor Size (size of invasive component not stated) AND proportions of in situ and invasive not known]. By virtue of the lymph node metastasis, this must be an invasive breast carcinoma. The size of the invasive component is unknown.
