SEER EOD-88, 3rd Ed, 110. January 1998

Question:

EOD-Size of Primary Tumor--Breast: The path report provides a size for both the Paget disease and the underlying intraductal component in the breast. Should we assume the Paget disease to be invasive and code the size of the primary tumor to that invasive component? See discussion.

Discussion:

For example, path diagnosis for resection gave the size of the Paget disease as 1 mm and the size of the underlying intraductal tumor as 4 cm. Should size for this breast case be coded to 040 or 003, less than 3 mm.

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Size of Primary Tumor field to 040 [4 cm], the size of the larger underlying intraductal tumor. Paget disease is classified according to the size of the underlying in situ or invasive tumor. Paget with an underlying in situ tumor is staged as in situ to match the AJCC classification of this disease process.
