Active clinical trials for "Prostatic Neoplasms"

Adherence (or compliance with) a medication regimen is generally defined as the extent to which patients take medication as prescribed by their health care providers. The adherence to medications has close relation to effectiveness of the therapy. The primary objective of this study is to observe the adherence to treatment with oral clodronate (PDC, proportion of days covered, number of days in which clodronate is taken according to treating physician recommendation) in patients with malignancy. The secondary "hypothesis generating" objective is to describe the relation between adherence to treatment with oral clodronate and efficacy of the therapy (skeletal events, pain).

Patients with advanced prostate cancer usually receive some kind of pharmaceutical castration or undergo surgical castration. At the investigators department the pharmaceutical treatment is most often given with a 3 month interval. Over the last few years new drugs, which allow for lees frequent treatment, have been developed. The purpose of this study is to assess how the treatment affects patients and if our current patients would prefer to receive treatment at different intervals than they do at the present time. At the same time the investigators will assess how surgical treatment affects our patients. This will be assessed by patient questionnaires administered at our clinic.

The objective of this study was to describe treatment patterns of leuprorelin over 2 years using an intermittent, adjuvant regimen in participants with advanced prostate cancer (PCa)

RATIONALE: Diagnostic procedures, such as magnetic resonance imaging (MRI), may help find prostate cancer and learn the extent of disease. PURPOSE: This clinical trial is studying the safety of MRI and to see how well it works in diagnosing prostate cancer.

In this study the investigators want to determine if the detection of lymph node is applicable in prostatectomy by laparoscopy.

This study will primarily compare the effectiveness of surgery and radiation for localized prostate cancer, the most common male cancer. It will focus on modern technologies and control for differences in patients and treatments that may affect both cancer-related and patient-reported outcomes (such as impotence and incontinence). By figuring out what treatments "work best, in which patients and in whose hands", it will help men with prostate cancer make better decisions regarding their care.

The purpose of the protocol is to assess the rate of castration resistance, disease progression and overall survival over a 3-year period post-androgen deprivation therapy (ADT) induction in a study cohort of patients with advanced disease.

RATIONALE: Screening may help doctors find prostate cancer sooner, when it may be easier to treat. PURPOSE: This research study is looking at whether patients who are being screened for prostate cancer have been previously screened.

RATIONALE: Gathering information about how often osteonecrosis of the jaw occurs in patients receiving zoledronic acid for bone metastases may help doctors learn more about the disease and provide the best follow-up care. PURPOSE: This clinical trial is studying osteonecrosis of the jaw in patients with cancer who are receiving zoledronic acid for bone metastases.

RATIONALE: Collecting and storing samples of bone marrow and tissue from patients to test in the laboratory may help the study of cancer. PURPOSE: This laboratory study is comparing proteases (enzymes that break down protein) in patients with prostate cancer that has spread to the bone with patients who do not have cancer that has spread to the bone.
