Question:

EOD-Size of Primary Tumor: Can size be coded from a needle bx that removes all of the invasive tumor and just leaves a "focus of in situ"? See Description.

Discussion:

For example: needle bx diagnosis is "tiny focus of tissue highly suspicious for tubular ca." The lumpectomy path states "single focus of low grade DCIS, no residual ductal ca." Can size be coded 001?

Answer:

Code tumor size to 001 [Microscopic focus or foci only] for the invasive component. Code the tumor size 990 for cases diagnosed in 2004 and forward. Disregard the microscopic tumor found at further resection.
