Question:

CS Tumor Size--Breast: How is this field coded when a core needle biopsy removes the majority of the tumor? See Discussion.

Discussion:

Rule 4.j on page 128 of the 2004 SEER Manual states "Do not code the tumor size from a needle biopsy unless no residual tumor is found on further resection".

Example: 3/04/04 core biopsy Rt breast grade 1 infiltrating ductal carcinoma tumor size 0.8cm. 3/10/04 Lumpectomy: 3mm focus of residual infiltrating ductal carcinoma. If we can not take the size of the core needle biopsy, do we use the residual size of 3mm or the clinical size which was 1cm on mammogram?

Answer:

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 the tumor size from the mammogram. Do not code the tumor size from the needle biopsy because residual tumor was present in the lumpectomy specimen.
