Filter by:Background: - Blister fluid contains many of the same biomarkers (substances that can be used to determine the effects of certain kinds of treatments) as blood and urine samples, particularly regarding changes in the skin. - The Radiation Oncology Branch and others are conducting research studies that require blood and urine samples from healthy volunteers and from patients with cancer. In addition to these samples, researchers would like to collect the fluid from blisters to examine markers of inflammation in the skin. Objectives: - To compare blood, urine, and blister fluid samples of patients with cancer who are undergoing radiation therapy to that of volunteers without cancer who will not be receiving radiation therapy. - To gather more information about the effects of radiation therapy on the skin and body fluids of individuals. Eligibility: - Patients 18 years of age and older who will be receiving radiation therapy for either breast or prostate cancer. - A separate group of healthy volunteers will also participate in this study. Design: - Physical examination and blood samples to determine eligibility for the study. - Blister induction, conducted before the start of radiation treatment, at completion of radiotherapy (last day of treatment), and at a visit 12 months after the end of radiation treatment. - Blisters will be created through the use of a suction blister device on the hip (for patients with prostate cancer) or on the treated breast or location of removed breast (for patients with breast cancer). - Blisters will take approximately 30 minutes to form, and fluid will be removed with a needle and syringe. - Blood and urine samples will also be collected at this time. - Radiation treatment for breast or prostate cancer will be conducted according to standard procedures, or as directed by a separate research protocol. - Evaluations during the treatment period: - Physical examination, including vital signs and body weight checks, and pregnancy test for women who can become pregnant. - Blood and urine tests. - Disease evaluation. - Post-treatment evaluations: - Clinic visits at months 1, 3, 6, 9, and 12 after the end of radiation therapy for physical examination and disease assessment. - Study will end 1 year after the final radiation treatment, upon the collection of the final (third) blister fluid sample.
Our objective is to evaluate the clinical outcomes for the anatomic radical perineal prostatectomy (RPP) for the surgical management of prostate cancer. We will report the perioperative, oncologic, and functional outcomes in patients undergoing the radical perineal prostatectomy at our institution.
The purpose of this study is to evaluate the role and effectiveness of conversion to sirolimus versus CNI reduction in renal transplant patients with prostate cancer.
This study concern a prospective cohort pf patients with latent prostate cancer. We study the specific survival at 10 years of patients who accept an active control.Patients inclusion are realized in 2 stages: - patient with inclusion criteria (PSA < 10 ng/ml, clinical stage T1c or T2a, Gleason < or = 6) are registered if they accept a second prostate biopsy in a 3 months delay - after analyse of second biopsy in central laboratory and confirmation of latent prostate biopsy, patients are included if they accept active control Included patients will have 1 biopsy by years the first two years and then 1 biopsy each 2 years during 8 years. If progression of cancer happens during the 10 years control, active control will be stopped and patient will be treated by surgery and chemotherapy.
The study aims to evaluate the safety and performance of the RTPS in patients with localized prostate cancer.The RTPS is an investigational device and requires permanent implantation of a small radioactive fiducial, called the Blip, in the prostate.
To gather information on the safety of monotherapy of Casodex® tablets 80 mg, targeting prostate cancer patients who have no history of having received treatment by either endocrine therapy (including surgical castration).
This is a single institution, open label, phase II study in androgen-independent prostate cancer patients who are chemotherapy-naïve. Patients will receive Torisel® 25 mg weekly. Treatment continues until disease progression, patient's withdrawal, unacceptable toxicity or the investigator's discretion.
Cyproterone acetate (CPA) is a steroidal antiandrogen which has affinity with progesterone and with glucocorticoid receptors. Cyproterone acetate is long-term proven effective treatment of inoperable carcinoma of the prostate. Sexual functions remain very important in men with prostate cancer. However sexual functions are deteriorating fast with course of the disease. The influence of CPA on sexual functions remains controversial. IIEF-5 erectile dysfunction questionnaire is currently widely used validated simple scoring system for diagnosing of erectile dysfunction and belongs to most used systems in Czech Republic. At present there are no data on CPA influence on IIEF-5 scored erectile dysfunction within the use of its indication in prostate cancer.
RATIONALE: Diagnostic procedures, such as radionuclide imaging using calcium-41 (41Ca) chloride aqueous solution, may help predict progressive disease in patients with prostate cancer and bone metastasis. PURPOSE: This clinical trial is studying how well calcium-41 (41Ca) chloride aqueous solution works in diagnosing patients with prostate cancer and bone metastasis.
This is a phase II multi-center study to determine the clinical impact of using a patient-specific genomic expression signature of androgen receptor (AR) activity to determine therapy for patients with castration-resistant metastatic prostate cancer (CRPC). After patient eligibility is determined, the genomic signature will be applied to fresh frozen tissue harvested from a metastatic lesion during image-guided biopsy. After assessing for androgen receptor activity, the investigators will select patients for either continued androgen manipulation with nilutamide (high AR activity) or targeted therapy with dasatinib (low AR activity). Once patients develop a first progression on either arm, patients will receive combination therapy with dasatinib and nilutamide. The primary aim is to estimate the median progression free survival in men with CRPC treated according to tumor AR activity. The investigators hypothesize that by treating men based upon AR activity, median progression free survival (PFS) will improve from a historical median of 3.0 months to 6.0 months.
