Active clinical trials for "Prostatic Neoplasms"

This study will observe patients who receive external beam radiation for prostate cancer. These patients will be localized and tracked (targeted) with the Calypso 4D Localization System. These patients will have a uniform treatment plan with reduced PTVs (prostate treatment volume) and will be assessed at multiple time points for quality of life and side effects related to radiation therapy.

The purpose of this study is to assess the effect of palliative pelvic radiation on symptoms and quality of life among patients with incurable prostate and rectal cancer.

Androcur is an antiandrogenic drug, which blocks the action of male sex hormones. Androcur is used for treatment of advanced prostate cancer. This study investigates the effect of Androcur on quality of life of prostate cancer patients who are taking the drug for 12 months

In the past ten years, newer drugs with more selective affinity for the alpha-receptor have been introduced. Alfuzosin (Uroxatral) and Tamulosin(Flomax are two second generation alpha-blockers. In the course of our clinical proctice, both drugs have been used routinely. This retrospective comparison is intended to be a priliminary comparison of their effectiveness and side effects.

The ability of sildenafil to aid in the return of erections after nerve-sparing radical prostatectomy has been established. Patients who had either one or both neurovascular bundles spared demonstrated dramatically better responses to "as needed" sildenafil than those that did not, and a positive erectile response to sildenafil was only seen in patients in whom at least one NVB was spared. This study has been designed to determine if sildenafil taken nightly works better than sildenafil on as "as needed" basis for the return of erectile function. The investigators hypothesis is that sildenafil taken nightly promotes a more rapid return of erectile function after nerve-sparing laparoscopic radical prostatectomy.

The objective of this study is to investigate possible factors that will affect the choice of androgen deprivation therapy in prostate cancer patients. This is a cross-sectional study performed in Prince of Wales Hospital in Hong Kong. One hundred patients will be recruited for this study.

The purpose of this study is to evaluate the yearly conditional prostate-specific antigen (PSA) progression-free survival (PFS) probabilities in high-risk localized prostate cancer (HR LPC) participants following radical prostatectomy (RP) and perioperative hormonal therapies (that is, hormonal treatment before RP and / or after RP) over 5 years.

Dosimetry efficacy evaluation of the hydrogel spacer

This is an open-label positron emission tomography/computed tomography (PET/CT) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-NOTA-BBN-RGD in prostate cancer patients. A single dose of 111-148 Mega-Becquerel (MBq) 68Ga-NOTA-BBN-RGD will be injected intravenously. Visual and semiquantitative method will be used to assess the PET/CT images.

The intention of this study is to investigate how many patients with prostate cancer, planned to be treated with LHRH analogues without history of surgery or radiotherapy, are suffering from LUTS. In addition the effect of LHRH analogues on the improvement of theses primary LUTS symptoms over time will be investigated.
