Active clinical trials for "Prostatic Neoplasms"

RATIONALE: Exercise may help improve mobility and relieve fatigue and/or weakness in cancer survivors. It is not yet known whether exercise is more effective than standard therapy in improving mobility and reducing fatigue and/or weakness in older cancer survivors. PURPOSE: This randomized clinical trial is studying exercise to see how well it works compared to standard therapy in improving mobility and reducing fatigue and/or weakness in older cancer survivors.

The researchers propose to investigate a relatively new anesthetic procedure, in order to maximize patient comfort and minimize the use of narcotics after a radical prostatectomy.

RATIONALE: Eating a diet low in residue (fiber, fat, and certain milk or vegetable products) may help prevent or reduce diarrhea caused by pelvic radiation therapy. PURPOSE: This randomized clinical trial is studying a low-residue diet to see how well it works compared to no dietary intervention in treating diarrhea in patients who are undergoing radiation therapy to the pelvis for uterine, cervical, or prostate cancer.

Web-Based Support for Informal Caregivers in Cancer Brief Summary (including hypothesis): Informal caregivers need information, skills and emotional support to address physical, spiritual, and emotional needs associated with chronic illnesses including late stage cancer. Unfortunately, current conditions force clinicians to reduce their interaction time with patients and informal caregivers. Complimentary methods must be developed to provide needed information and support to caregivers. The proposed research will measure and explain the impact of two computer-based support systems that meet caregiver needs and facilitate information exchange with clinicians. The system, CHESS (Comprehensive Health Enhancement Support System) is a non-commercial computer system that provides patients with disease specific information, emotional support and skill building tools. In the expanded form to be tested in this study, CHESS with Caregiver Support (CGCHESS) will also provide the caregiver with more information, support and skills training related to palliative care. CGCHESS will be further enhanced to communicate essential patient and caregiver information to clinicians prior to a scheduled clinic visit and when patient symptoms exceed a threshold. The investigators' primary hypothesis is that CGCHESS + Clinician Report (CR) will reduce caregiver burden more than CGCHESS because of the additional support caregivers and patients receive from clinicians who have access to the CHESS clinician report. Secondary analyses will study the mechanisms of the CHESS effect. Specifically the investigators anticipate that the CHESS effect on caregivers will be mediated by the CHESS effect on interaction patterns with clinicians, satisfaction with clinical visits and by the CHESS effect on four patient outcomes (quality of life, negative affect, average severity of nine common late-stage cancers).

The study populations consist of a sample of the patient population (men aged 40-79 years) of a large, group model HMO and a community sample of men age 50-79. Follow-up interviews of men randomly assigned to the intervention and control groups are being conducted by telephone to assess issues related to prostate cancer screening and the men's use of the CD-Rom educational intervention.

Randomized clinical study of two CAM therapies, 1) Reiki and 2) Relaxation Response Therapy with Cognitive Restructuring counseling (RRT with CR), compared to an education-only control arm in patients about to begin an eight-week course of external beam radiotherapy (EBRx) for prostate cancer. Generally, we would like to examine the feasibility of studying Reiki and RRT with CR in patients with prostate cancer, and to obtain preliminary results on the effectiveness of these treatments compared to controls. Specific objectives: Determine the proportion of eligible patients who agree to participate in the study Measure compliance with CAM therapy interventions Measure compliance with physiologic and psychological outcome measurement assessments Assess differences between experimental and control groups on measures on depression, anxiety, quality of life, salivary cortisol levels and an immunomarkers

Newly diagnosed localized prostate cancer patients face difficult decisions about treatment and management; including radiation therapy, radical prostatectomy, brachytherapy, and observation. Previous studies have cited patient preference and physician recommendation for treatment as major roles in treatment decisions.

RATIONALE: Telephone counseling by a nutritionist and a personal trainer may improve physical function and quality of life in patients who have early-stage breast cancer or prostate cancer. PURPOSE: Randomized clinical trial to compare the effectiveness of a home-based, diet and exercise-based counseling program with that of a standard home-based counseling program in promoting health in patients who have early-stage breast cancer or prostate cancer.

The hepatic enzyme, cytochrome P450 3A4 (CYP3A4) is important for the metabolism of many drugs including taxanes. Previous reported studies reported a decreases in docetaxel exposure in prostate cancer patients compared to patients with other solid tumours. The difference was 1.8-fold for intravenous administration and 2.8-fold for oral administration. The underlying mechanism for these observations remains to be elucidated. The lower docetaxel exposure with IV and oral docetaxel treatment might be related to a higher CYP3A4 activity in prostate cancer patients. Therefore, it is important to directly compare the CYP3A4 activity with a phenotyping test in prostate cancer patients and patients with other types of solid tumours. This is an in vivo phenotyping studying using midazolam as a probe for CYP3A4 activity in patients with prostate cancer and patients with other solid tumours. The primary objective is the comparison of CYP3A4 activity in prostate cancer patients versus male patients with other types of solid tumours by use of an oral midazolam phenotyping test. Secondary objectives are: (1) measurement of plasma concentrations of midazolam and it's two primary metabolites (1'-hydroxy midazolam and 4'-hydroxy midazolam), (2) determination of the metabolite pharmacokinetics of midazolam. (3) retrospective assessment of single nucleotide polymorphisms of CYP3A4. The exploratory objective is to differentiate between gastro-intestinal and hepatic CYP3A4 activity with oral and intravenous administration of midazolam.

A phase I, randomized, open-label and active-control study to assess the PK, PD and safety profiles of LY01005 versus goserelin comparator to be conducted in the USA.
