Active clinical trials for "Prostatic Neoplasms"

The purpose of this trial with Zometa is to investigate the effect ZOMETA 4 mg (zoledronic acid for injection in 100mg solution ) has in preventing associated bone loss in prostate cancer patients with bone metastasis when administered in conjunction with hormonal cancer therapy. This trial will seek to determine the effect of ZOMETA in stabilizing and increasing bone mineral density in these patients. This prospective, open-label, single arm, multicenter study will enroll approximately 200 prostate cancer patients with a history of at least one documented bone lesion documented by bone scan or radiograph. Patients must already be receiving hormone therapy and meet the following additional criteria: 18 years of age or older Histologically confirmed diagnoses of prostate cancer Confirmed objective evidence of metastatic bone disease as evidenced by bone scan or radiograph Received or will receive hormonal treatment also know as androgen deprivation therapy with an LHRH agonist or other hormonal treatments Throughout the course of this 12-month trial, patients will be identified based on the duration of established hormonal treatment at the time of enrollment. Each patients duration of participation will be up to 56 weeks including a 4 week screening, 48 week treatment and a 4 week follow up.

Phase I: The goal of this clinical research study is to find the highest dose of estramustine phosphate administered intravenously in combination with a fixed dose of Taxol (paclitaxel) that can be given safely to participants with prostate cancer who have failed to further benefit from hormone treatment. Phase II: The goal of this clinical research study is to find out if the combination of the drugs estramustine phosphate and paclitaxel will shrink or control prostate cancer that has not responded to hormone treatment. A second goal is to find out if the side effects of these drugs can be reversed. The safety of these drugs will also be studied.

RATIONALE: Testosterone can stimulate the growth of prostate cancer cells. Hormone therapy may be effective treatment for prostate cancer. It is not yet known which regimen of hormone therapy is most effective for stage IV prostate cancer. PURPOSE: This randomized phase III trial is studying two different regimens of hormone therapy and comparing how well they work in treating men with stage IV prostate cancer.

RATIONALE: Radiation therapy (RT) uses high-energy x-rays to damage tumor cells. Androgens can stimulate the growth of prostate cancer cells. Hormone therapy using flutamide, goserelin, and leuprolide may fight prostate cancer by reducing the production of androgens. It is not yet known which regimen of antiandrogen therapy is most effective for prostate cancer. PURPOSE: Randomized phase III trial to study the effectiveness of radiation therapy with or without antiandrogen therapy in treating patients who have stage I or stage II prostate cancer.

RATIONALE: Hormones can stimulate the growth of prostate cancer cells. Hormone therapy may fight prostate cancer by reducing the production of androgens. Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known whether hormone therapy plus surgery is more effective than hormone therapy plus radiation therapy for prostate cancer. PURPOSE: This randomized phase III trial is studying giving hormone therapy alone to see how well it works compared to giving hormone therapy together with bilateral orchiectomy or radiation therapy in treating patients with stage III or stage IV prostate cancer.

This phase II trial studies how well lapatinib ditosylate works in treating patients with a rising prostate-specific antigen (PSA), a protein made by the prostate gland, indicating that prostate cancer has come back after previous treatment. Lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and may delay or prevent the progression of prostate cancer.

Radical prostatectomy provides potentially curative removal of the cancer. However, it subjects patients to the morbidity and mortality of the surgery and may be neither necessary nor effective. Expectant management does not offer potential cure. However, it provides palliative therapy for symptomatic or metastatic disease progression, avoids potentially excessive and morbid interventions in asymptomatic patients, and emphasizes management approaches for focus on relieving symptoms while minimizing therapeutic complications. The primary objective of this study is to determine which of two strategies is superior for the management of clinically localized CAP: 1) radical prostatectomy with early aggressive intervention for disease persistence or recurrence, 2) expectant management with reservation of therapy for palliative treatment of symptomatic or metastatic disease progression. Outcomes include total mortality, CAP mortality, disease free and progression free survival, morbidity, quality of life, and cost effectiveness.

RATIONALE: Combining calcitriol with dexamethasone may increase the effectiveness of therapy by making cancer cells more sensitive to dexamethasone. PURPOSE: Phase I trial to study the effectiveness of calcitriol combined with dexamethasone in treating patients who have prostate cancer that has not responded to previous hormone therapy.

VA Cooperative Study #553 is designed to prospectively evaluate the efficacy of early adjuvant chemotherapy using docetaxel and prednisone added to the standard of care for patients who are potentially cured by radical prostatectomy but who are at high risk for relapse. The standard of care is surveillance, with the addition of androgen deprivation at the time of biochemical relapse. This study will assess the effect of adding early chemotherapy to the standard of care on progression free survival in Veterans at high risk for progression after prostatectomy.

RATIONALE: Green tea extract contains substances that may slow the growth of certain cancers and may prevent the development of new cancers. PURPOSE: Phase II trial to determine the effectiveness of green tea extract in treating patients who have metastatic prostate cancer that has not responded to hormone therapy.
