PURPOSE For select men with low risk prostate cancer active surveillance is more often being considered a management strategy. In a multicenter retrospective study we evaluated the actuarial rates and predictors of remaining on active surveillance, the incidence of cancer progression and the pathological findings of delayed radical prostatectomy.

Our radioimmunoassay for prostatic acid phosphatase was compared to commercial radioimmunoassay kits. A close correlation among all 3 assays was found in control groups, and in patients with benign prostatic hyperplasia and adenocarcinoma of the prostate. These results also were compared to recent reports from other centers using similar methodologies. In 7(More)
Registration of histological slices to volumetric imaging of the prostate is an important task that can be used to optimize imaging for cancer detection. Such registration is challenging due to physical changes of the specimen during excision and fixation, and misalignment of the histological slices during preparation and digital scanning. In this work, we(More)
Standardized and reproducible preclinical models that recapitulate the dynamics of prostate cancer are urgently needed. We established a bank of transplantable patient-derived prostate cancer xenografts that capture the biologic and molecular heterogeneity currently confounding prognostication and therapy development. Xenografts preserved the(More)
PURPOSE We determine if mapping of the cavernous nerve during radical prostatectomy using intraoperative cavernous nerve stimulation with tumescence monitoring results in improved erectile potency compared to conventional nerve sparing. MATERIALS AND METHODS A prospective, randomized, single blinded study was performed on 61 patients at 6 centers.(More)
The metabolic organization of both normal and malignant prostate cellular phenotypes involves some unusual and surprising features. In particular, both conditions exhibit ratios of NADH/NAD+ and NADPH/NADP+ characteristic of high oxidative states despite a chronic shortage of O2 in both conditions. In this paper, we observe that, in prostate cancer cells,(More)
PURPOSE We explored the efficacy of the ginsenoside Rh2 and examined its impact on the effective dose of paclitaxel and mitoxantrone in the LNCaP prostate tumor model. MATERIALS AND METHODS Cultured LNCaP cell viability was assessed following treatment (48 hours) with Rh2 (0 to 40 microM) alone or in combination with paclitaxel and mitoxantrone. Synergism(More)
UNLABELLED What's known on the subject? and What does the study add? Active surveillance for prostate cancer is gaining increasing acceptance for low risk prostate cancer. Focal therapy is an emerging tissue preservation strategy that aims for treat only areas of cancer. Early phase trials have shown that side-effects can be significantly reduced using(More)
4635 Background: Docetaxel is active for hormone refractory prostate cancer (HRPC) and may have additive effects if combined with androgen ablation in hormone naïve disease. Potential beneficial or adverse effects of combination vs sequential chemo-hormonal regimens are poorly defined. The objective of this trial was to assess the tolerability and(More)
OBJECTIVE To evaluate the safety and effectiveness of high-intensity focused ultrasound (HIFU) in patients with benign prostatic hypertrophy (BPH). PATIENTS AND METHODS The study comprised 25 patients (mean age 67 years: range 47-84) with BPH treated using the Sonoblate HIFU device. Patients were evaluated before and after one treatment of HIFU using the(More)
