Active clinical trials for "Prostatic Neoplasms"

Robot assisted prostatectomy reduces the patients' postoperative pain and leads to rapid rehabilitation. But pneumoperitoneum affects the kidney. The increase of stress hormone reduces the glomerular filtration and the vaso-contraction of renal vessels leads the renal ischemia. Remifentanil is analgesics coupled with μ opioid receptor. In high dose of remifentanil, it is associated with κ and δ receptors, which leads to renal protection effect in animal study. Also, remifentanil infusion during anesthesia showed a diuretic effect. The purpose of this study is to investigate the remifentanil effect on renal function during robot assisted prostatectomy.

The purpose of this study is to evaluate the number of circulating tumor cells (CTC) before and after treatment using an experimental method for detecting CTC, compared to commercial CTC assay results, in patients with prostate, breast or colorectal cancers. Experiments will be done to develop a new assay technique and also test how CTC react to commonly used drugs. This information will be analyzed to determine if the experimental assays can be helpful in the future to predict how a patient's cancer may react to certain treatments. The research experiments will also attempt to grow CTC for long-term or "immortal" cell lines that can be further studied for proteins and gene mutations related to the specific tumor (not familial), and testing for sensitivity to drugs. Blood samples will be collected at specific time points during routine medical care from patients with prostate, breast, colorectal or other solid tumor cancer. Samples will also be collected from patients with no cancer for comparison purposes. Samples for the experimental tests will be identified only by codes and results will not be shared with participants. Patients with prostate, breast or colorectal cancer will also have blood samples drawn for commercial CTC assays as part of their standard care.

This is a prospective study in which patients with castrate-resistant prostate cancer and bone metastases will undergo imaging, donate blood, bone marrow and urine samples, and where possible primary tumour and bone metastatic tissue, before and during treatment with ZD4054, an orally active specific endothelin-A antagonist. The samples will be used primarily for biomarker studies, and it is hypothesized that these will inform on the mechanism of action of this drug. Magnetic Resonance Imaging (MRI) will be performed to evaluate emerging functional imaging endpoints as markers of early response in bone metastatic prostate cancer.

RATIONALE: Studying samples of tissue, blood, and urine from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors find better ways to treat the cancer. PURPOSE: This research study is looking at tissue, blood, and urine samples from patients with advanced prostate cancer.

The goal of this behavioral research study is to look at patients' quality of life after treatment or management for prostate cancer.

The goal of this research study is to collect information on the side effects of proton radiation therapy given for the treatment of prostate cancer as well as the effect of proton therapy on quality of life. Information on your treatment and how you react to the treatment will be collected. Researchers will use this information to try to understand how people tolerate proton radiation therapy for prostate cancer.

This study aimed to evaluate the correlation of change in body composition and oncological outcomes of prostate cancer patients under androgen deprivation therapy(ADT).

Androgen deprivation therapy (ADT) by surgical castration or administration of LHRH agonists or antagonists is the gold-standard systemic treatment of Prostate Cancer. The efficacy, severity and frequency of side effects of ADT vary from a patient to another. The exact cause of this variability is not known, however certain genetic polymorphisms affecting enzymes implicated in the synthesis and metabolism of sex-steroids seem to be involved in these processes. To perform a longitudinal study to evaluate the prevalence of various genetic polymorphisms affecting genes in the sex-steroid synthesis and metabolism pathway (CYP1A1, CYP1B1, CYP19A1, 17HSD, HSD3B1, AR, ESR1, ESRRG, IL6, TNF-alpha) in men with Prostate Cancer receiving ADT and the possible association between polymorphisms and frequency and severity of side-effects of ADT.

Background: Prostate cancer (PCa) is the most common cancer for men. When treated early enough it is typically curable. However, common treatments, such as radical prostatectomy and radiation therapy, often result in significant negative outcomes with regard to sexual, psychological and social function. Both men and partners have identified the need for more information and support to address sexual health concerns after treatment. However, very few sexual rehabilitation interventions have been developed and rigorously assessed. Purpose: The investigators propose to develop and pilot test a new program to meet the sexual health needs of men with PCa and their partners using an online, professionally facilitated education/support program. The goals of the program are to improve sexual function, intimacy and mood for men and their partners after treatment for localized PCa. The program will be offered through Cancer Chat Canada, an existing and well-tested Canadian platform for professionally facilitated support group programs. What Participants Can Expect: A total of 24 men and their female partners (48 individuals) will be recruited and assigned to one of two groups. The first group will participate in the program immediately; the second group will be offered the program after a 5-month delay. The decision about which group will start immediately and which later will be made randomly (by chance). Both groups of men and partners will be asked to complete questionnaires three times and, at the end of the program, to provide the researchers feedback about how satisfied they were with the program, the changes they made, things they learned as a result of the program, and suggestions for improving the program. Participants must have access to a computer, an Internet connection and be willing to attend online, chat room meetings each week for 1.5 hours for 6 weeks. Implications: Sexual rehabilitation is a high need for men affected by PCa, but is difficult to access. The investigators hope to improve access to sexual health care through this study.

This trial is an interrogation of patients with prostate cancer to evaluate socioeconomic effects of radiotherapy. Patients with percutaneous or interstitial or combined percutaneous and interstitial radiotherapy are included. Beside medical effects and adverse events, it's prospectively needed to extensively inform patients about socioeconomic aspects associated with radiotherapy. The interrogation comprises to collect possible costs and expenditures during and after therapy. Aspects especially concerning post therapy period include additional consultations, individual applied alternative medical care, need for additional medical aids (salves, medicine, bandages) and changes in professional and social situation. It's figured out in what extend costs are absorbed by health insurance coverage. In Germany there is no appropriate trial with respective patient population and respective therapy. Primary endpoint is the evaluation of therapy concerning and follow-up costs as well as changes in social and professional situation. Secondary endpoints are quality of life, adverse events of therapy and the correlation of quality of life, adverse events and economic aspects for the patient and the health insurance coverage.
