Active clinical trials for "Prostatic Neoplasms"

No treatments have been shown to slow prostate cancer progression after radical prostatectomy. We hypothesize that a carbohydrate restricted diet will slow prostate cancer growth. A total of 60 men with a rising prostate-specific antigen (PSA) after failed primary treatment will be recruited and randomized to either a low-carbohydrate diet (<20 grams carbohydrates/day) or a no-diet control (standard of care) for 6 months. The primary outcome is PSA doubling time.

This study will evaluate the local control rate as well as acute and late toxicity rates of stereotactic body radiotherapy (SBRT) for the treatment of organ confined prostate cancer.

The purpose of this research study is to compare profiles in the blood and tears of patients with and without prostate cancer with the goal of developing a method of separating men with aggressive and non-aggressive disease.

Rationale: Dose escalation in external-beam irradiation has proven to benefit outcome in local prostate cancer. Randomized trials were performed up to doses of 78 Gy in 2 Gy fractions. Nevertheless, the five-year biochemical relapse rate still was approximately 35% in the high-dose arm. Therefore further dose escalation seems to be required. A feasibility study up to appr. 85 Gy on the entire prostate has already been performed and showed acceptable toxicity when combined with adequate position verification. Higher doses to the entire prostate are expected to increase severe toxicity. As local recurrences only occur at the site of the primary macroscopic tumour area the next step in increasing the dose should be an ablative boost to the macroscopic tumour alone, while electively irradiating the rest of the prostate to the current gold standard dose. Feasibility of this approach has been shown for an ablative dose of 95 Gy to the macroscopic tumour within the prostate.

Men treated with neoadjuvant luteinizing hormone-releasing hormone (LHRH)-agonists such as leuprolide and goserelin for prostate cancer will become hypogonadal due to hormonal suppression and demonstrate increased bone turnover and consequent bone loss at the hip and spine. This bone loss can be prevented by treatment with 35 mg/week of risedronate.

The aim of this study is to determine if 3 monthly infusions of zoledronic acid, given over one year, improves the bone mineral density in osteoporotic patients undergoing androgen deprivation therapy for prostate cancer

For patients with Prostate Cancer advances in medical technology have enabled us to identify "accessory" (additional) pudendal arteries (called APA) while performing a laparoscopic radical prostatectomy (a scope with a video camera is used during the surgery). APAs running near the prostate gland are identified in approximately 1 in 3 to 4 patients. However, large APAs, like the ones looked for in this study, are identified in 15-18% of all patients. These arteries are preserved more than 80% of the time, depending on their size and location.With this study, we plan to evaluate whether APAs supply blood to the penis and male erections, as well as the amount supplied.

To assess by MR Imaging the lesions induced by WST09-mediated photodynamic therapy (PDT) in patients with recurrent or persistent localized prostate cancer following definitive radiotherapy using different light doses and multiple illuminating fibres.

Phase IIIb, Open-label, randomized, controlled multi-centre study. Induction therapy phase for 6 months where all subjects receive 2 ELIGARD depot injections. Those subjects with hormone responsive prostate cancer will be randomized and will receive either intermittent or continuous ELIGARD treatment for 36 months. Following this treatment period, subjects will enter a long-term follow-up period for 48 months.

The purpose of this study is to determine the proportion of patients with a serological prostate specific antigen (PSA) by day 85.
