2018 SEER Manual, 107-109. Tumor Size--Clinical

Question:

Tumor Size/Bladder: The 2018 SEER Coding and Staging Manual says to use imaging over physical exam as priority for determining tumor size. If a bladder tumor is 4 cm visualized on cystoscopy, and is 2.8 cm on CT scan, which should be used as the clinical size? Is cystoscopy (endoscopy) a clinical exam or imaging?

Discussion:

Answer:

For the case described here, use the size from the CT scan. Physical exam includes what can be seen by a clinician either directly or through a scope. A tumor size obtained visually via cystoscopy is part of a physical exam. Therefore, the imaging (CT) tumor size is preferred. Use text fields to describe the details.
