Active clinical trials for "Prostatic Neoplasms"

The purpose of this research study is to monitor the feasibility and outcome of the Active Surveillance Program for men with low risk prostate cancer.

In this study we are comparing two forms of radiotherapy. This study is being done because it is not clear at present time whether intensity modulated radiotherapy (IMRT) can reduce side effects of radiotherapy compared to standard radiotherapy (called 3D-Conformal Radiotherapy).

The purpose of this study is to monitor the safety of continued DN-101 and docetaxel treatment for subjects previously enrolled in DN101-002 (ASCENT) or DN101-004 (NSCLC) Studies.

RATIONALE: Learning about the long-term effects of chemoprevention drugs, such as finasteride, in patients with prostate cancer may help doctors plan better treatment and follow-up care. PURPOSE: This clinical trial is following patients who were diagnosed with prostate cancer while undergoing treatment with either finasteride or a placebo on the Prostate Cancer Prevention Trial (PCPT).

Surgery and irradiation for organ confined prostate cancer provide excellent long-term cancer control but they may be accompanied by a risk of side effects that decrease quality of life. Due to the stage migration of prostate cancer, the potential for patients to undergo unnecessary treatment and the risk of treatment related morbidity, has been increased.Alternative strategies that offer the possibility of delaying, obviating or minimizing the impact of treatment maintaining the same oncological long term results have been investigated. Despite pros and cons active surveillance has not gained popularity in men with low risk prostate cancer as only 7% of men with localized prostate cancer remain in active surveillance. Traditionally solid tumors have been treated with radical surgery but selective, organ sparing therapies are now common for tumors of the breast, skin and kidney, resulting in equivalent rates of cancer control, lower morbidity rates and less disfigurement. With this in mind the potential role of focal ablative therapy for localized prostate cancer might be considered. The researchers will investigate the feasibility and the efficacy in term of quality of life and oncologic results of focal therapy by a pilot not randomized prospective study in a patients with localized prostate cancer who meet low risk criteria based on clinical, biopsy and imaging data.

The investigators try to investigate the benefit of early administration (immediately after urethral catheter removal) of sildenafil after nerve-sparing RALP for 3 months. The investigators will compare the potency rates up to 2 years after nerve-sparing RALP in men with on- demand sildenafil 100mg dosing from the early postoperative period (immediately after urethral catheter removal) with from the delayed postoperative period (3 months after RP).

RATIONALE: Studying samples of blood and urine from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This laboratory study is measuring plasma and urine biomarkers in patients with advanced prostate cancer that did not respond to hormone therapy.

This is a phase II trial looking at the feasibility of HistoScanning- based dose-painting image- guided interstitial brachytherapy in non- metastatic prostate cancer Endpoints: Primary endpoint Evaluation of the feasibility of HistoScanning- based dose-painting image- guided interstitial brachytherapy Secondary endpoints Evaluating tumor response using HistoScanning Evaluating locoregional recurrence rates by measuring PSA Analysis of the correlation between tumor response as determined by HistoScanning and PSA response Evaluating the safety dose-painting image- guided interstitial brachytherapy by recording serious adverse events

The purpose of this trial is to compare two similar treatments for patients diagnosed with prostate cancer. The two treatment arms being compared are: (Standard Arm) hormone therapy, which will prevent the production of the male hormone, testosterone, by the testicles, and pelvic external beam radiation therapy (EBRT) followed by a high-dose, conformal EBRT boost versus (Investigational Arm) hormone therapy and pelvic EBRT followed by a brachytherapy boost (implantation of radioactive iodine sources or "seeds" into the prostate). The hypothesis of this trial is that more patients may experience 5 year actuarial freedom from biochemical recurrence of their prostate cancer following treatment with the investigational arm. Biochemical failure is declared on the date when the post treatment prostate specific antigen (PSA) is > 2 ng/mL above the lowest level previously recorded.

The purpose of this study is to investigate the safety, tolerability and anti-tumor effects of treatment with samarium Sm-153 lexidronam in combination with docetaxel in patients with castrate metastatic prostate cancer.
