Filter by:The purpose of the present study is to investigate if endurance training can be used as a therapeutic action against the adverse metabolic disturbances and unfavourable changes in body composition that accompany the androgen deprivation therapy (ADT) treatment in prostate cancer patients.
To assess the effect of neo-adjuvant GnRH antagonist, degarelix, versus LHRH agonist on intratumoral levels of androgens.
RATIONALE: Studying samples of blood or tumor tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. PURPOSE: This clinical trial studies prostate-specific antigen (PSA) antibody levels in samples from patients treated for prostate cancer on trial ECOG-E9802.
In Europe, prostate cancer (PCa) is the most common solid neoplasm, with an incidence rate of 214 cases per 1000 men, outnumbering lung and colorectal cancer. Early detection tests have been developed in order to identify PCa while it is still confined to the prostate gland. The two most commonly used tests are digital rectal examination and serum prostate-specific antigen (PSA) level: however, most of cases is detected in the so called T1c stage, i.e. for PSA increasing only. As marker, PSA is organ-specific but not cancer-specific, and its levels may change as result of physical activity, sexual activity, in the presence of benign prostatic hyperplasia (BPH), acute and chronic prostatitis, as well as in the presence of PCa. A total serum PSA of 4.0 ng/ml has traditionally been used as threshold for considering prostate biopsy and large programs for the early detection of prostate cancer have shown that almost 70% of cancer cases can be detected using a PSA cutoff of 4.0 ng/ml. However, using a PSA threshold of 4.0 ng/ml 20% to 25% of prostate cancer cases are not detected (false-negative) and the false-positive rate is 65%. To improve the usefulness of PSA for identifying patients who require biopsy, the PSA threshold has been lowered at 2 ng/ml; moreover, the levels of free and bound PSA have been assessed, together with PSA density (the rate of PSA over the prostate volume) and PSA velocity (the rate of PSA increase), which seem to have some validity for detecting prostate cancer. Recent studies have shown that other new biomarkers could be used in the diagnosis of early prostate cancer as they showed a higher sensitivity and specificity. In the last two years, several investigators showed that PSA isoform [−2] proPSA (p2PSA) and its derivatives, namely, percentage of p2PSA to free PSA (%p2PSA) and the Prostate Health Index [PHI; (p2PSA / free PSA) × √tPSA)] improve the accuracy of total PSA (tPSA) and percentage of free PSA (%fPSA) in predicting the presence of PCa at prostate biopsy and they are also related to PCa aggressiveness at biopsy. The aim of this study is to confirm the diagnostic and prognostic predictive value of prostate-specific antigen isoform p2psa and its derivates, %p2psa and prostate health index in the detection of prostate cancer in patients with a PSA 2-10 ng/ml and/or suspicious DRE.
Investigators will perform a study with 162 patients in whom there is a strong suspicion of prostate cancer that has returned to the body after having a prostatectomy. Half of these patients will have radiotherapy decision-making and delivery per the usual routine, and half of these patients will have the radiotherapy decision and volumes guided by the FACBC test (anti-1-amino-3-[18F]fluorocyclobutane-1-carboxylic acid (anti-3- [18F]FACBC). The major goal of the investigation is to see whether the FACBC improves the selection and the cancer control rates of post-surgery patients with a rising PSA who undergo radiotherapy.
This is a double-blind, placebo-controlled, multiregional Phase1/2 study to characterize the pharmacokinetic and pharmacodynamic responses to orteronel when administered concomitantly with prednisone in Chemotherapy-Naive Participants With Castration-Resistant Prostate Cancer
The purpose of this study is to determine the safety and efficacy of enzalutamide vs bicalutamide in asymptomatic or mildly symptomatic patients with prostate cancer who have disease progression despite primary androgen deprivation therapy.
The purpose of this study is to provide access to abiraterone acetate for patients who have completed 12 cycles of abiraterone acetate treatment in Clinical Study COU-AA-001 and continue to receive clinical benefit from this treatment.
This clinical trial studies high-dose stereotactic body radiation therapy (SBRT) in treating patients with low-, intermediate-, or high-risk localized prostate cancer. SBRT may be able to send x-rays directly to the tumor and cause less damage to normal tissue
The purpose of this study is to determine which technique in using a vacuum erection device (VED) is best. Erectile dysfunction (ED) after robotic prostate cancer surgery is a concern for both the surgeon and the patient. Recent studies have shown that beginning to use the vacuum pump on a daily basis starting with in 2-8 weeks may help prevent the start of penile shrinkage. This is a potential issue that can occur because of decreased blood flow after prostate cancer surgery. This study will allow researchers to determine and compare vacuum therapy techniques and erectile function outcomes of patients who have prostate cancer surgery
