Question:

EOD-Pathologic Extension--Prostate: If there is residual tumor in the distal urethra on prostatectomy, does that mean there is distal urethral margin involvement? See discussion.

Discussion:

2/98 Prostate bx: Right apex, right mid and right base positive for adenocarcinoma.

6/1/98 Radical retropubic prostatectomy w/ bilateral pelvic lymph node dissection. Pathology: Residual adenocarcinoma in distal urethra, right lateral sections and posterior lobe. Right apical margin, other margins, seminal vesicles, and 7 pelvic LN negative for malignancy.

Answer:

For cases diagnosed 1998-2003:

For the example above, code the EOD-Pathologic Extension field to 34 [extending to apex] because most of the right side is involved.

The pathology report says all margins are free. The comment on residual tumor in the urethra, meant the first surgery did not completely remove tumor tissue from the urethra, it does not mean that tissue is at the margin.
