  • Apologies to those authors whose good work is not mentioned due to time constraints;

  • Abstract Book number indicated in parentheses;

  • RCT = Randomised Controlled Trial

  • IHC = Immunohistochemistry

  • RALP = Robot-assisted Radical Prostatectomy

  • BCR = Biochemical Recurrence

  • CSS = Cancer-specific survival

Bph basic science

BPH: Basic Science

  • Ückert (549) showed with IHC PDE5 co-localises with key mediators of the Nitric Oxide pathway in human prostate TZ smooth muscle

Bph medical

BPH: Medical

  • Gacci (334) RCT: following 2 weeks Tam alone, 60 patients randomised to combination Vardenafil 10mg + Tamsulosin vs. placebo + Tam 12 weeks improved erectile function and storage LUTS;

  • Hamidi Madani (335) and Roerhborn (336) demonstrated in RCTs (n=132 & n=606) daily Tadalafil improves IPSS (= to alpha-blockers), ED and QoL

Bph medical1

BPH: Medical

  • Van Kerrebroeck (327): Tamsulosin OCAS + Solifenacin RCT (n=930): IPSS improved for patients with BOO and “substantial” storage LUTS using combination;

  • Roerhborn (329) COMBAT RCT (n=4844) subgroup analysis by prostate volume (PV), demonstrated that after 4 years treatment combination Tamsulosin + Dutasteride significantly improved IPSS, QoL, Qmax at all PV >30cc, except in glands >58cc treated with Dutasteride alone.

Bph injection therapy

BPH: Injection Therapy

  • Marberger (325) reported RCT (n=380), 47% failing tamsulosin for LUTS/BOO. Intraprostatic injection of BotoxA significantly reduced IPSS vs. placebo in failed Tam cases;

  • Mirkin (440) mean PSA reduced by 40% 6 months after intraprostatic injection of BotoxA

Bph surgery

BPH: surgery

  • Chandrasekar (114), Geavlete (115), Neyer (116), Mamoulakis (117) & Yip (118) conducted small RCTs of monopolar TURP vs bipolar or plasmakinetic vaporisation: short-term results - complications, catheter time - favoured the newer technologies;



  • Abughosh (587) studied 500 Canadian men undergoing TRUS & biopsy: 21 % rectal swabs grew ciprofloxacin-resistant bacteria, mostly E. coli; Trend towards less sepsis in patients given iodine rectal wall cleaning;

  • Lee (589) reviewed 52 patients with prostatic abscess 2000-2010 in Seoul. TUR drainage resulted in shorter hospital stay & less risk of recurrence vs. TRUS-guided needle drainage.

Cancer basic science translational

Cancer: Basic science/translational:

  • Angulo (401), Ropero (512) & Stadler (510) performed DNA hypermethylation profiling of tumor /benign samples; each identified a panel of genes frequently methylated in high-grade & stage disease and in RP patients experiencing BCR, including tumor suppressor gene APC;

  • Boormans (406) Gene fusions & Erg expression using IHC may aid PIN and cancer diagnosis within prostate biopsies;

Cancer basic science translational1

Cancer: Basic science/translational

  • Dahlman (526) & Hoogland (746) reported IHC for β-microseminoprotein (MSMB) is predictive for BCR in RP specimens, but not in needle-biopsies of RP patients;

  • Morgan (123) evaluated urinary transcription factor EN2 in 190 PC patients / controls, concluding it is a highly specific and sensitive candidate biomarker of prostate cancer.

Cancer basic science translational2

Cancer: Basic science/translational

  • Brown (620) & Yokomizo (833) Statins reduce: Invasive behaviour & colony morphology;

    AR sensitivity & amplification;

  • Fankhauser (631) studying CRPC cultures, adrenal androstenedione is major precursor for intraprostatic testosterone synthesis;

  • Donovan (643) ProTect study: serum IGF-I does not correlate with screen-detected cancer risk, unlike IGFII, -BP2 & 3.

Cancer psa screening

Cancer: PSA Screening

Schröeder (15) ERSPC Rotterdam (n=35150): Screening reduced metastatic disease by 30% over a median 11 year follow-up, becoming obvious after 5 years: NNT=23

Cancer psa screening1

Cancer: PSA Screening

  • Frånlund (23) & Roobol (24) reported the presence of LUTS to reduce risk of cancer diagnosis in screened Swedish & Dutch populations;

  • Zhu (20) Bul (419) & Santti (25): Interval cancers in ERSPC were significantly more aggressive and lethal than screen-detected cancers; could shortening the screening interval below 4-years improve CSS?

Cancer screening diagnosis

Cancer: Screening & Diagnosis

Roobol (16) & Van Vugt (17): ERSPC Risk Calculator was upgraded to predict high-grade and advanced disease; it outperforms PSA alone in both screened and clinically-referred men

Cancer diagnostics

Cancer: Diagnostics

  • Miyakubo, Stephan, Semjonow, Lazzeri, Bektic & Nava (128-131, 635,636) studied serum

    pro-PSA & “prostate health index” ([phi=[-2]proPSA/fPSA)x√tPSA] Beckmann Coulter combined assay): more accurate than total PSA and predicts aggressive disease features;

  • Arumainayagam (133) evaluated Multi-parametric MRI using TPB reference in 65 patients, finding >85% NPV for significant PC.

Cancer biopsy

Cancer: Biopsy

  • Roy (307) correlated multiple biopsy procedures to worse potency after NS-RALP;

  • Ahmed (528), Lecornet (533) & Hameed (313) conducted studies suggesting that men considering repeat biopsy or undergoing Active Surveillance should be evaluated with Transperineal template biopsy after initial TRUS-guided biopsy to reduce risk of under-diagnosis

Radical prostatectomy

Radical Prostatectomy

  • Calza (456) RCT LRP vs RARP (n=100) less opiate and “rescue” analgesia required for robotic cases;

  • Videos: Trinh (V22), Wagner (V24) & Srivastava (V27) demonstrated the V-Loc™ polyglyconate absorbable barbed suture RCT in posterior reconstruction & vesico-urethral anastomosis, saving 2 - 8 minutes per case

Cancer node staging

Cancer: Node Staging

Joniau (568) LN mapping in 65 RPs using a “super-extended” template: only 39% correctly staged by obt. LND; standard ePLND missed 21% N+ cancer

Cancer node staging1

Cancer: Node Staging

  • Schiavina (562) & Briganti (567): ePLND improved BCR-free survival regardless of nodal status;

  • Joniau (563) conducted multivariate analysis of 781 high-risk RP, concluding number of LN removed did NOT correlate with CSS;

  • Briganti (566) correlated number +ve nodes, regardless of location, with CSS in 372 N+ patients following RP/ePLND

Cancer node staging2

Cancer: Node Staging

  • Schiavina (565) A monolateral LN dissection on the side of unilateral positive biopsy missed 20-35% contralateral N+

Adjuvant radiation therapy

Adjuvant Radiation Therapy

  • Bolla (218, 227) presented 10-year results of EORTC 22911 Adjuvant RT vs Wait & See (n=1005); No difference in overall survival; Conflicting results of SWOG S8794 possibly explained by > risk factors in SWOG patients;

  • Gallina (674) reviewed 1123 RP patients, presenting data suggesting full continence recovery may be delayed or prevented by adjuvant RT
