SEER EOD-88, 3rd Ed, 152
Question:
EOD-Size of Primary Tumor: Can the term "filling defect" be used to code tumor size? See Description.
Discussion:
Site: Bladder
CT abd/pelvis: 4 cm filling defect of the bladder encasing jetstream of distal ureter. 2-3 cm lesion may be extension to bladder. KUB: 3-4 cm filling defect within bladder.
Cystoscopy: large bladder tumor with small tumor extending out of the large tumor.
OP Findings: Large tumor on right of bladder extending from bladder neck lateral and posterior
Pathology: TURB: High grade TCC, Grade III with focal lamina propria invasion.
Answer:
For tumors diagnosed 1998-2003:
Information on size from imaging/radiographic techniques can be used to code size when there is no more specific size information from a pathology or operative report, but it should be taken as low priority, just above a physical exam.
The term "filling defect" from a CT or KUB may be used to code tumor size for bladder in the absence of more reliable size information from path, operative or endoscopic reports.
