Active clinical trials for "Prostatic Neoplasms"

RATIONALE: Studying samples of blood in the laboratory from patients before and after treatment may help doctors learn more about the effects of the treatment on cells. PURPOSE: This clinical trial is studying samples collected from patients with localized prostate cancer who received treatment on clinical trial NCI-00-C-0154.

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.

RATIONALE: Chemotherapy may cause blood clots to form in the thigh, leg, and lung. This study may help doctors understand how often blood clots occur in patients undergoing chemotherapy. PURPOSE: This clinical trial is studying how often blood clots occur in patients undergoing chemotherapy for solid tumors, including colorectal cancer, stomach cancer, lung cancer, ovarian cancer, pancreatic cancer, prostate cancer, or metastatic breast cancer

The goal of this clinical research study is to find out if men who have a type of prostate cancer that has been classified as "low risk" can safely not be treated for the disease. Doctors want to know if patients with "low risk" cancer can avoid or postpone therapy and the related side effects and still live as long as patients who immediately receive therapy. This is an investigational study. There are no medications used in this trial. About 1,000 patients will take part in this study. All will be enrolled at MD Anderson.

ARI103094 is a follow-up study in adult male subjects who have received investigational product (either dutasteride or placebo) in the REDUCE Study (REduction by DUasteride of prostate Cancer Events), ARI40006, A Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study of the Efficacy and Safety of Dutasteride 0.5mg Administered Orally Once Daily for Four Years to Reduce the Risk of Biopsy-Detectable Prostate Cancer. There are 2 parts to this REDUCE Follow-Up Study, Part A and Part B: REDUCE Follow-Up Study, Part A, is a 2 year observational study which will follow eligible subjects for 2 years after completion of the 4 Contact in the REDUCE study. Eligible subjects for Part A, the 2 Year Observational Study fall into 3 groups as follows: (1) REDUCE subjects who completed treatment with investigational product (dutasteride or placebo) through the REDUCE 4 Year study visit [Visit 10], (2) REDUCE subjects who developed prostate cancer, were withdrawn from investigational product and participated in Prostate Cancer follow-up until the REDUCE 4 Year study visit [Visit 10P] or (3) REDUCE subjects who were withdrawn from investigational product and participated in observational phone follow up until the REDUCE 4 Year phone call after withdrawing from IP (expected Visit 10). The objective of this observational study for eligible REDUCE subjects is to collect and summarize data on prostate cancer (the incidence of newly diagnosed prostate cancers and changes in prostate cancer diagnosed during the REDUCE study) and serious adverse events (SAEs) for 2 years beyond the prospectively planned 4 year double blind, placebo-controlled study, REDUCE. REDUCE Follow-Up Study, Part B, is for collection of cancer positive prostate biopsy tissue blocks/slides from subjects who were diagnosed with prostate cancer in the REDUCE study.

Prospective, non-comparative, non-interventional, observational study to collect and analyse real life environment data on advanced prostate cancer patients receiving combination treatment of medical or surgical castration and bicalutamide according to routine medical practice in Croatia. The main aim is to evaluate change of PSA level and prescribing practices based on prostate cancer stage.

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

RATIONALE: Measuring levels of transforming growth factor-beta (TGF-beta) in the blood of patients with epithelial cancers (head and neck, lung, breast, colorectal, and prostate) may help doctors predict how patients will respond to treatment with radiation therapy. PURPOSE: This research study is measuring levels of TGF-beta in patients with epithelial cancers who are undergoing radiation therapy.

The male sex-hormone called testosterone is known to play a key role in the growth of prostate cancer. The usual treatment for the disease involves suppression of hormones (testosterone) by anti-hormonal treatment for an unknown period of time until the cancer progresses. This anti-hormonal treatment usually consists of injections every three months with an LHRH(Leutinizing Hormone-Releasing Hormone) agonist and a short course of anti-androgen pills, which together help to lower the production of testosterone. Long-term hormonal treatment has potentially serious side effects and is expensive. In this study, hormonal treatments will be with held from those patients eligible and willing to participate. The aim of this study is to see if we can decrease the amount of hormone injections that patients require. This might lead to a decreased side effects(such as decrease in bone health, cardiovascular problems and metabolic syndrome which occurs when several health conditions happen at the same time and can lead to an increased risk of heart disease, stroke and diabetes) as well as to decrease the cost of hormonal therapy to treat prostate cancer.
