Active clinical trials for "Prostatic Neoplasms"

Adrenal androgens are serum biomarkers of interest that may help guide abiraterone acetate treatment, particularly at the time of progression. Biomarkers may also help identify pathways to resistance of abiraterone acetate treatment. The most practical way of approaching this question is to explore surrogate biomarkers of prostate cancer including quantification of pharmacodynamic endocrine biomarkers.

This study will enroll 200 men with clinical suspicion of prostate cancer due to higher serum level of PSA than 2.5 ng/ml or abnormal digital rectal examination. Anatomical magnetic resonance imaging (MRI) and diffusion weighted imaging (DWI) at 3 Tesla (T) magnetic field using surface coils will be used to non-invasively predict the presence or absence of prostate cancer. Targeted TRUS guided biopsy based on MRI findings will be performed in addition to routine twelve core TRUS biopsy. Moreover, selected serum and urine biomarkers as well as biomarkers extracted from fresh biopsy sample will be collected and correlated with the presence or absence of prostate cancer.

The purpose of this study is to detect factors influencing decision making for treatment pathways of hormone-naïve prostate cancer patients with and without comorbidities receiving medicinal androgen deprivation therapy (Degarelix or LHRH agonists).

The purpose of this study is to collect some parameters which may help to provide guidance on how Androgen Deprivation Therapy (ADT) drugs are renewed and physician satisfaction.

Biomarkers of bone resorption will be measured in the blood of patients with bone metastases from prostate cancer during the course of their illness. Changes in these biomarkers will be correlated with the patient's treatment with antiandrogen therapy and bisphosphonates and the response and/or progression of their cancer. It is hoped that serial measurement of these biomarkers may allow therapeutic monitoring in the future with successful individualisation of bisphosphonate therapy for metastatic prostate cancer.

The purpose of this study is to evaluate an imaging capability Prostate Mechanical Imager (PMI), a PC-based device utilizing a transrectal probe with pressure sensor arrays and motion tracking system, aimed at providing composite elasticity images of the prostate.

This research study is being done to collect regular and routine follow-up information related to the outcome of treatment for prostate cancer. This study is also being done to relate treatment outcome to measurement of substances in the blood such as prostate-specific antigen (PSA) and other markers. Also environmental and genetic factors that might be responsible for prostate cancer are being investigated.

The goal of this study is to learn more about how we measure depression in elderly cancer patients (patients aged 70 and older). Depression is one of the most common causes of emotional distress in the elderly and continues to be under-recognized. This is a problem because depression can have a negative impact on quality of life. The symptoms of depression are linked to poor health outcomes and higher costs of health care. In fact, depression is one of the top five concerns facing the elderly today.

For primary surgical treatment of prostate cancer the investigators compare the classic open surgery (radical retropubic prostatectomy, RRP) versus robot-assisted laparoscopic surgery (RALP). Oncological results are obtained at standard follow-up consultations through Prostate-Specific Antigen (PSA) measurement to detect biochemical recurrence. Functional results (continence, potency, quality of life) are obtained through standardised questionnaires. Currently the investigators perform all of their prostatectomies in a robot-assisted manner. For results of the open surgery the investigators send questionnaires to patients who had the operation in the past.
