ABSTRACT
Purpose: To determine the initial oncologic results (pathology) of specimens removed by laparoscopic radical
prostatectomy (LRP) by examining the surgical margins.
Patients and Methods: The 70 consecutive LRP procedures performed for clinically localized prostate can-
cer at Eastern Virginia Medical School from April 2001 to November 2002 were reviewed for preoperative
and important intraoperative variables. The initial histopathology report and a prospective review by a sin-
gle genitourinary pathologist for margin status as well parenchymal exposure of benign glands were assessed.
Postoperative prostate specific antigen (PSA) levels were noted.
Results: The clinical stage distribution was as follows: T1
c
59, T2
a
10, and T2
b
1. The preoperative
median PSA value was 6.96 ng/mL. The mean operative time was 307 minutes. The mean estimated blood
loss was 298 mL. The prospective pathologic review results were as follows: 1 pT
0
(1.4%), 60 pT
2
(85.7%),
and 9 pT
3
(12.8%). The overall positive surgical-margin rate was 15.7%. Of those patients with pT2 disease;
8 specimens (13.3%) had a positive margin, whereas 33% of patients with pT
3
disease had a positive surgi-
cal margin. Parenchymal exposure of benign glands on the inked surface was recognized in 8 patients (13.3%).
Data from PSA assays 1 month postoperatively were available in 69 patients. Serum PSA was undetectable
(0.1 ng/mL) in 67 men (97%).
Conclusion: An LRP can offer surgical margins comparable to those of open procedures series reported in
the literature. Long-term progression and survival outcome data are necessary before this procedure should
be offered as a replacement for open prostatectomy.
INTRODUCTION
T
HE GROWING APPEAL of minimally invasive surgery
has prompted urologists to adapt these techniques for var-
ious procedures. Such operations are gradually becoming the
standard of care for such operations as live donor nephrec-
tomies, radical nephrectomies, and pyeloplasties. Radical
retropubic prostatectomy (RRP) and perineal prostatectomy
(PP) are established approaches for the surgical removal of the
malignant prostate. Laparoscopic radical prostatectomy (LRP)
is a new operative procedure that must be compared with the
standard approach before it is widely applied. Intraoperative
and postoperative data are essential to making these compar-
isons.

Intact surgical removal by assessment of margin status
addresses the critical issue of cancer control. The steep learn-
ing curve is also a practical resource-centered issue. The Euro-
pean experience with LRP has demonstrated promising results.
Certainly, to have any parity with RRP, the laparoscopic ap-
proach must be successful in removing the entire prostate with-
out capsular intrusion. The inability to grasp the organ manu-
ally and the necessity of working without tactile feedback might
intuitively appear to be disadvantages of the procedure. How-
