CONVERTING FROM OPEN TO ROBOTIC PROSTATECTOMY: INSTITUTIONAL IMPACT ON NUMBER OF PELVIC LYMPHNODES RETRIEVED DURING ROBOTIC−ASSISTED LAPAROSCOPIC RADICAL PROSTATECTOMY (RALRP)Jennifer Yates *, Joseph Renzulli MD , Harry Iannotti MD , George E Haleblian MD and GyanPareek MD .
The mean number of lymph nodes obtained during robotic PLND was 3.2 and the mean number obtained by open PLND was 6.9 (p< 0.001).
Robot−assisted laparoscopic PLND yielded fewer lymph nodes compared to open PLND at the time of radical prostatectomy for organ confined disease.
In patients presenting with a high risk of lymph node involvement based on preoperative staging, open PLND yields a higher number of lymph nodes compared to robotic PLND and should be considered the gold standard.
PATHOLOGIC UPGRADING AND UPSTAGING WITH IMMEDIATE REPEAT BIOPSY FOR PATIENTS ELIGIBLE FORACTIVE SURVEILLANCERyan K Berglund MD *, Timothy A Masterson MD , Kinjal C Vora MD , Scott E Eggener MD , James A Eastham MD and Bertrand D Guillonneau MD .
A retrospective review of consecutive patients undergoing repeat biopsy within 3 months of a first positive biopsy
from March 2002 until June 2007 was analyzed. Patients were considered eligible if they had a PSA < 10 ng/ml, clinical stage <
T2b, Gleason pattern <4, <4 cores positive, and no single core with > 50% cancer involvement.
Of the repeat biopsies performed, 27/104 (26%) were negative,
58/104 (56%) had Gleason score = 6,
17/104 (16%) had Gleason score 7,
one patient had Gleason score 9,
10/104 (10%) of patients had > 3 cores involved on repeat biopsy,
12/104 (12%) had > 50% involvement of at least one core.
A total of 27/104 (26%) patients were upgraded or upstaged.
Immediate repeat biopsy in patients with prostate cancer being considered for AS resulted in more than one

421 consecutive patients treated with radical prostatectomy and bilateral PLND
Preoperative plasma levels of transforming growth factor−b1 (TGF−b1), interleukin−6 (IL−6), interleukin−6 soluble
receptor (IL−6sR), vascular endothelial growth factor (VEGF), vascular cell adhesion molecule−1 (VCAM1), Endoglin, urokinase
plasminogen activator (uPA) urokinase plasminogen inhibitor−1 (PAI−1), and urokinase plasminogen receptor (uPAR) were
measured using commercially available enzyme immunoassays in Multivariable models were used to explore the gain in the
predictive accuracy of the models. The accuracy was quantified by the c−index statistic and was validated with 200 bootstrap
In standard multivariable analyses that adjusted for the effects PSA, biopsy Gleason sum, and clinical stage,
TGF−b1 (p<0.001), IL−6sR (p<0.001), IL−6 (p<0.001), VCAM−1 (p<0.001), VEGF (p=0.008), Endoglin (p=0.002), and uPA (p<0.001)
were associated with biochemical recurrence.
The multivariable model containing standard clinical variables alone had an accuracy of 71.6%.
The addition of TGF−b1, IL−6sR, IL−6, VCAM1, VEGF, Endoglin, and uPA increased the predictive accuracy by 15% to
86.6% (p<0.001) and demonstrated virtually perfect calibration.
LONG−TERM SURVIVAL PROBABILITY IN A COHORT OF OVER 20,000 IN MEN WITH PROSTATE CANCER TREATED CONSERVATIVELY OR WITH DEFINITIVE TREATMENT (RADIOTHERAPY OR RADICAL PROSTATECTOMY)Robert A Leung *, Jay K Jhaveri , Rajiv Yadav , Sandhya Rao , Terry Field , Edward H Wagner , Mani Menon , E Darracott Vaughanand Ashutosh K Tewari MD .

IS DIABETES MELLITUS ASSOCIATED WITH POORLY DIFFERENTIATED PROSTATE CANCER (PCa)?Firas Abdollah *, Andrea Salonia , Andrea Gallina , Vincenzo Scattoni , Rayan Matloob , Patrizio Rigatti and Francesco Montorsi .
1874 consecutive radical prostatectomy between February 1997 and July 2007.
Six and a half percent (120/1874) of them were diabetic at the moment of PCa diagnosis.
No significant differences between diabetic and non diabetic men were observed regarding age (66±6 vs 65±7 years;
p=0.7), PSA level at diagnosis (9.5±9 vs 9.8±10 ng/ml; p=0.1), and pathological stage (pT2 67%, pT3 33%, pT4 0% vs pT2 71%,
pT3 28%, pT4 1%).
Significantly higher percentage of poorly differentiated PCa were found in diabetic patients
(pGS <6 : 12%, pGS 6: 21%, pGS 7: 55%, pGS >7: 12% vs pGS <6 : 16%, pGS 6: 26%, pGS 7: 52%, pGS >7: 6%; p=0.02).
Multivariate: significantly higher risk of having a poorly differentiated PCa in diabetic patients (OR: 2.4; P=0.05).
the other parameters included in the multivariate analysis (age, total PSA, and pathological stage) were
not significantly correlated to the presence or not of DM.
Diabetic patients have a higher risk of having a poorly differentiated PCa at final pathology following radical
prostatectomy than patients who are euglycemic.
HIGHER CHOLESTEROL INCREASES THE RISK OF BIOCHEMICAL FAILURE AFTER RADICAL PROSTATECTOMY:RESULTS FROM THE SEARCH DATABASE GROUPLionel L Banez MD *, Robert J Hamilton MD, MPH , William J Aronson MD , Martha K Terris MD , Joseph C Presti MD , Christopher J Kane , Christopher L Amling MD and Stephen J Freedland MD ..
471 men from the Shared Equal Access Regional Cancer Hospital (SEARCH) database who
underwent radical prostatectomy from 1998 to 2007 and had available cholesterol, low−density lipoprotein
(LDL) and high−density lipoprotein (HDL) levels and known statin medication use status prior to surgery.
increased serum cholesterol (p=0.001) and increased serum LDL (p=0.007) increased the risk for biochemical recurrence after surgery.
HDL was not associated with biochemical relapse (p=0.79).
Men in the highest quartile of serum cholesterol (³ 217 mg/dl) had 2.5 times higher risk for biochemical relapse
(HR 2.49, 95% CI 1.28 − 4.86, p=0.007) compared to men in the lowest quartile (<167 mg/dl).

The study population consisted of 10,333 men treated with radical prostatectomy (RP) (n=6196) or EBRT (n= 4137)
between 1983 and 2004 without neo− or adjuvant hormonal therapy.
The diagnosis of bladder, lung and colo−rectal cancer were established with the ICD−9 and surgery codes,
(cystectomy, lobectomy or pneumectomy and colectomy with or without rectal resection).
Overall, 92 (0.9%) cystectomies, 82 (0.8%) lung cancer surgeries and 228 (2.2%) surgeries for colo−rectal cancers
In univariable analyses, the rate of cystectomies (log−rank p=0.002), of treatments for lung cancer (log−rank
p<0.001) and for colo−rectal cancers (log−rank p<0.001) were higher in patients treated with EBRT relative to patients treated
At multivariable analyses, after adjusting for age, baseline comorbidities and year of treatment EBRT predisposed to a
3.0−fold higher rate of cystectomy for bladder cancer (p=0.04),

case−control study of aggressive prostate cancer of 1012 subjects
prostate cancer presenting with one or more of the following clinical criteria:
clinical T stage >T2b, initial PSA >10 ng/mL or biopsy Gleason score >6.
Controls had no diagnosis of prostate cancer, a serum PSA <4 ng/mL, and were frequency matched to cases for age, institution
Assessed food intake by a validated questionnaire and calculated nutrient intake.
Both EPA and DHA were associated with a dose−response reduction in prostate cancer risk (ps for trend £0.0001).
The Odds Ratios (95% Confidence Intervals) comparing the highest quartile of fatty acid intake to the lowest equaled 0.44 (0.30 −
0.65) and 0.37 (0.25 − 0.55) for DHA and EPA, respectively.
Intake of food containing the long−chain omega−3 fatty acids EPA and DHA is inversely associated with
aggressive, clinically significant, prostate cancer.
The potential protective effect of EPA appears to be stronger among men with
the rs274557 COX2 variant. This might be expected because COX2 is a key enzyme involved in the metabolism of fatty acids.
SERUM TESTOSTERONE IS ASSOCIATED WITH AGGRESSIVE PROSTATE CANCER: RESULTS FROM THE BALTIMORE LONGITUDINAL STUDY OF AGINGPhillip M Pierorazio MD *, Luigi Ferrucci , Anna E Kettermann , E Jeffrey Metter and H Ballentine Carter MD .
INTRODUCTION AND OBJECTIVE:
Evaluated the relationship between testosterone and the development of high−risk prostate cancer.
Prospectively evaluated serum androgen concentrations and the development of high risk prostate cancer.
Cohort was 729 male participants in the Baltimore Longitudinal Study of Aging who had sex steroid
measurements prior to a diagnosis of prostate cancer, or last visit for those without prostate cancer (no cancer,
n= 611; prostate cancer not high risk, n=83; prostate cancer high risk, n=35).
High risk cancer was defined as death from prostate cancer, or >20 at diagnosis, or Gleason score >8.
After adjusting for age and date of diagnosis, calculated free testosterone was significantly associated with high
risk prostate cancer (RR=1.25; 95% CI=1.03 to1.51, p=0.022).
Higher levels of calculated serum free testosterone are associated with an increased risk of aggressive prostate
OBESE MEN HAVE LARGER AND HIGHER−GRADE TUMORS: CANCER: RESULTS FROM THE BALTIMORE AN ANALYSIS OF THE DUKE PROSTATE CENTER DATABASENicholas J Fitzsimons MD *, Leon Sun MD, PhD , Judd W Moul MD , John F Madden MD and Stephen J Freedland
Retrospective analysis of 2,171 patients treated with radical prostatectomy
Association between BMI and tumor volume and high−grade disease (Gleason 4+3 or
greater) was assessed
Increased BMI was significantly associated with younger age (p<0.001), black race (p<0.001), more recent year
of surgery (p<0.001), positive surgical margins (p<0.001), higher−grade disease in the surgical specimen
(p=0.03), and larger tumor volumes (p=0.003).
Higher BMI was associated with increased tumor volume (p<0.001) and high−grade
Men with a BMI of 35 kg/m2 or greater had nearly 40% larger mean tumor volumes than normal weight men
(5.1 vs. 3.7 cc).

TESTOSTERONE (T) LEVEL CORRELATES WITH SURVIVAL IN PTS WITH ADVANCED PROSTATE CANCER (APC): THE LOWER IS REALLY THE BETTERMassimo Perachino MD * and Valerio Cavalli MD .
162 consecutive pts with diagnosis of PC treated with ADT
T and PSA were measured every 3 months
age, stage, Gleason Score (GS), basal PSA, basal T, PSA nadir, time to PSA nadir, T after 6 m, T nadir and time to T nadir. Multivariate analysis was performed
With a mean follow up of 52.3 ± 33.2 months, 97 pts are dead (59.9%) and 65 pts are alive (50.1%).
Statistical analysis using Cox's model shows that serum T at 6 m correlates with pts survival (HR=1.92, p<.05).
Death risk is directly correlated not only to GS (p<.01) and to basal PSA (p<.01), but also to 6 m serum T level (p=.0286).
The lower the T level after 6 m, the longer the survival.
pt with GS 7 and pretreatment PSA 50 ng/ml has 60% 5−yr probability of survival if 6m T is 10 ng/ml. 5−yr
probability of survival decreases to 54.3% if 6m T is 40 ng/ml.

Data were obtained from patients with bone metastases secondary to HRPC who had urinary NTX assessments at
baseline and month 3 (n = 314)
Patients were stratified by baseline NTX
(normal [N group], < 64 nmol/mmol creatinine; elevated [E group], ³ 64 nmol/mmol creatinine).
All patients received standard anticancer therapies in addition to zoledronic acid.
Baseline NTX was elevated in 193 (62%) patients (E group).
NTX levels normalized within 3 months of zoledronic acid therapy in ~70% of the E group.
NTX normalization was associated with a significant 59% decrease in relative risk
of death (relative risk = 0.410; P < .0001) compared with patients whose NTX levels remained elevated.
percentage decrease in NTX at 3 months correlated with a continuum of benefit, with the longest survival in patients whose NTX
levels decreased ³ 75% (P < .0001 for comparison between percentage−reduction quartiles).

The databases of (RP) from three different Urological Departments were retrospectively analyzed.
Center A performed only perinealprostatectomies (PP) with no PNLD in patients with PSA < 10.
Center B performed a standard PNLD
center C performed an extended PLND including internal and common iliac LN.
The median of LN removed was 0, 6 and 14 and LN+ 0%, 1.2% and 6% respectively.
the risk of PSAF was increased in patients with PP and no PLND (Group A) vs extended PLND (Group C) (HR=1.49; p=0.017) but not
vs standard PLND (Group B).
standard vs no PLND did not reduce the risk of PSAF
extended PLND was associated with a risk reduction of 64% (HR=0.36; p<.0001).
Standard PLND was associated with 2 times more risk of PSAF (HR 2.11 p<.0001) compared to extended PLND.
Type of PLND was a stronger independent predictor than pStage, Gleason >7 and positive margin.
The data suggest that the extent of PLND can reduce the risk of biochemical recurrence after RP.

1052 men with negative LN on final pathology and complete data on the following parameters: 12 months of
follow−up, a known number of nodes removed, preoperative prostate−specific antigen (PSA), biopsy Gleason
score, clinical stage, pathological stage, and surgical margin status. met these criteria.
The primary endpoint of the study was biochemical failure, defined as PSA >0.2 ng/mL.
The number of LN removed was assessed as both a continuous and categorical variable (0−2, 3−5, 6−8, and 9+).
The categorical LN breakdown was as follows:
0−2 nodes, n=69; 3−5 nodes, n=280; 6−8 nodes, n=255; 9 or more nodes, n=448.
On univariate analysis, BCFR was significantly influenced by preoperative PSA (P<0.001), Gleason grade
(p<0.001), and pathologic tumor stage (p=0.001).
There was no significant difference found in BCFR among all lymph node categories.
On multivariate analysis controlling for stage, grade, and preoperative PSA, there was no significant difference found

Since 2001, 111 patients with intermediate risk PC were treated with HDR−B plus H−EBRT, without ADT.
The median age was 69 years.
Radiotherapy consisted of a single HDR−B fraction of 10 Gy to the prostate surface followed by H−EBRT to a dose of 50 Gy in 20 fractions.
The first 73 consecutive patients with minimum follow−up of 2 years were assessed for toxicity and disease control.
Repeat prostate biopsies and PSA control (Phoenix definition), were used to assess local control.
Median follow−up was 50.6 months. No patient presented acute grade III or higher gastro−intestinal or genito−urinary
toxicities. Late rectal toxicity grade II was seen in 5 patients and grade III in one. Five patients presented intermittent gross
hematuria, and one patient developed urinary incontinence.
After a minimum follow−up of 2 years, 42 patients (57.5%) underwent
a repeat prostate biopsy; the remaining either refused or were never offered the procedure.
Negative biopsies were found in 39/42 patients (92.9%); among the 3 positive biopsies, only one patient has true biochemical failure, while
the other two have stable serum PSA levels below 0.1 ng/dL.
Overall, eight patients (10.9%) failed the treatment, 6 with metastatic disease and 2
with biochemical failure.

total of 1513 men underwent RP for high risk disease, with a median follow−up of 8.7 years.
858/1513 (56.7%) men were found to have organ−confined tumors at RP.
Ten year cancer−specific survival (CSS) was 95%, with 90% of patients without local recurrence (LR)
55% free from biochemical recurrence (BCR, defined as a PSA > 0.4 ng/mL) (figure).
On multivariate analysis, Gleason score on biopsy (HR 1.3, p=0.006) and at RP (HR1.4, p=0.006),
pathological tumor stage (HR 1.8, p=0.04), positive lymph nodes (HR 2.3, p=0.02), and positive surgical margins (HR 2.1,
p=0.008) predicted death from prostate cancer.
Age, year of surgery, preoperative PSA, clinical stage, and the number of high
risk features did not affect survival.
Adjuvant hormonal therapy (n=356) decreased the risk of BCR (HR 0.36, p<0.0001), LR (HR 0.26, p<0.0001), and systemic
progression (SP) (HR 0.49, p=0.006) but did not significantly impact the risk of CSS (HR 0.59, p=0.11) or (OS) (HR 0.87, p=0.39).
PROSTATE SPECIFIC ANTIGEN TESTING AMONG THE ELDERLY: WHEN TO STOP?H Ballentine Carter MD , Anna E Kettermann *, Luigi Ferrucci MD, PhD , Patricia Landis BS , Bruce J Trock and E Jeffrey MetterMD.
INTRODUCTION AND OBJECTIVE:
We determined the proportion of men who developed aggressive prostate cancer by PSA and age to evaluate
the safety of discontinuing PSA testing among older men.
METHODS: The probability of aggressive prostate cancer (death from prostate cancer) by PSA and age was determined from a
Cohort participating in the Baltimore Longitudinal Study of Aging (National Institute on Aging).
PSA of 3.0ng/ml and above at the age of 75−80 years had a probability of death from prostate cancer
afterwards that continued to increase;
no subject at the age of 75−80 years with a PSA below 3.0ng/ml died of prostate cancer afterwards (P<.001, Fisher's exact test).
aggressive prostate cancer was defined as death from prostate cancer, or Gleason score 8 or above at diagnosis, or PSA 20ng/ml or above at diagnosis.
Men who have a PSA level below 3ng/ml at age 75−80 years are unlikely to develop aggressive prostate
cancer during their remaining life and for these men PSA testing might be safely discontinued.

METHODS: 550 consecutive patients with PCA were retrospectively evaluated
108 (19.6%) patients were < 55 years (Group 1),
442 (80.4%) patients were > 55 years (Group 2).
There were no significant differences between both groups with regard to clinical stage, number of positive
Biopsies and preoperative PSA serum concentration.
RP specimens revealed more locally advanced PCA in group 1 as compared to group 2: pT3b/4 PCA (p=0.05);
positive lymph nodes were significantly more often diagnosed in men < 55 years (27.3% vs. 12.7%, p=0.005).
Gleason Score 8−10 (30% vs. 19%, p<0.05) and positive urethral surgical margins (42% vs. 26%, p<0.05).
The 5−year biochemical progression−free survival was significantly lower in the low age group (62% vs. 82%,
p<0.007), the PCA − specific mortality was significantly higher in the low age group (18% vs. 6%, p<0.003).
DETECTION OF TMPRSS2−ERG FUSION TRANSCRIPTS AND PCA3 IN URINARY SEDIMENTS MAY IMPROVEDIAGNOSIS OF PROSTATE CANCERDaphneHessels *, Frank P Smit , Gerald W Verhaegh , J Alfred Witjes , Erik B Cornel and Jack A Schalken .
78 men with prostate cancer−positive biopsies and 30 men with prostate cancer−negative biopsies were included in
After DRE, the first voided urine was collected and urinary sediments were obtained. We used semi−quantitative
RT−PCR analysis followed by Southern−blot hybridization with a radiolabeled probe for the detection TMPRSS2−ERG fusion
transcripts in these urinary sediments.
A quantitative RT−PCR assay for PCA3 was used to determine the PCA3 score in the same sediments.
TMPRSS2−ERG fusion transcripts were detected in the urine after DRE with a sensitivity of 37%. In this cohort of
patients the PCA3−based assay had a sensitivity of 62%. When both markers were combined the sensitivity increased to 73%.
In men with persistently elevated serum PSA levels and history of negative biopsies the positive predictive value of
TMPRSS2−ERG fusion transcripts was 94%, suggesting that detection of TMPRSS2−ERG fusion transcripts could give a better
indication which patients require repeat biopsies.
combination of TMPRSS2−ERG and PCA3, improve the sensitivity for prostate cancer diagnosis.
