Filter by: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.
This study is being proposed to evaluate the use of moderate hypofractionated proton therapy in low and intermediate risk prostate cancer patients. Quality of life outcomes as well as gastrointestinal and genitourinary early and late toxicities will be analyzed and compared to conventional proton therapy regimens. It is thought that this regimen will produce comparable findings and would result in substantial health care cost savings, as well as, be more convenient for patients.
The purpose of this study is to determine the side effects and how effective CyberKnife stereotactic ablative body radiation (SABR) is in patients with prostate cancer. The CyberKnife system is a new type of radiation machine that uses a special system to precisely focus large doses of x-rays on the tumor. The device is designed to concentrate large doses of radiation onto the tumor so that injury from radiation to the nearby normal tissue will be minimal. The purpose of this evaluation is to see if this treatment will help patients with your condition and to evaluate the effect of this treatment on your quality of life over time.
The iCaRe2 is a multi-institutional resource created and maintained by the Fred & Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies.
Men with a BRCA1 or BRCA2 mutation are at increased risk for early onset, aggressive prostate cancer compared to men in the general population. Standard of care screening for men with a BRCA mutation includes PSA testing and digital rectal examination (DRE), the same as with men in the general population. This study is being done to assess whether there is value in using MRI as a screening tool to detect prostate cancer at an earlier stage than may otherwise be detected using standard of care screening (PSA, DRE). It is unclear whether MRI has utility as a screening tool in this specific population at high risk for aggressive disease.
This clinical trial is designed on the basis of an unmet clinical need, as well as other factors including: 1) the ability to identify subjects at high risk of dying early from their disease, 2) the fact that hormonal therapy has already been shown to improve survival when applied early in the natural history, 3) the availability of chemotherapy such as cabazitaxel that can improve survival in subjects with advanced disease and 4) that chemotherapy (docetaxel) given concomitant with hormone treatment has proven to prolong time to progression. It is the investigators hypothesis that a more appropriate group of patients who may benefit from the curative potential of systemic chemo-hormonal modality is that with minimal, but detectable disease who have a high probability of developing metastatic disease, clinical symptoms and eventually death from prostate cancer in a defined time frame. The investigators hypothesize further that the approach is likely to be more effective at a time of minimal tumour burden, resulting in minimization of the overall burden of therapy and better quality of life while on treatment. This trial will determine whether any benefit is gained by adding chemotherapy before hormonal therapy to hormonal therapy alone in the population of subjects with metastatic or high risk disease.
This study will evaluate a method to detect tumor cells that are circulating in the blood without getting a biopsy. The investigators already know from other studies that cancer tumors shed a small number of cells into the bloodstream every day. These are called circulating tumor cells (CTCs). Some early studies indicate the amount and type of CTCs in the blood can help determine the status of the tumor itself and the way it is responding to treatment. In this study, the investigators will compare the number of CTCs in the blood at different time frames before and after surgery to remove the prostate.
The Magnetic Resonance (MR) provides high resolution of soft tissue images allowing an appropriate assessment of the local extent of the disease. Recent studies have shown an increase in sensitivity and specificity for the detection of Dominant intraprostatic lesions when using multiparametric MRI as a diagnostic tool in the staging of the disease. Among the various irradiation techniques currently available for prostate cancer, Brachytherapy is the superior in terms of dose conformation; this conformation allows greater dose escalation, adjusting the isodoses to the prostate with exquisite accuracy, keeping healthy adjacent organs, such as the urethra and rectum, in a tolerable dose range Brachytherapy companies have recently developed software allowing for TRUS-MR image fusion. The purpose of this study is to demonstrate the feasibility of the delivery of a higher than prescription dose to the dominant intra-prostatic nodule as defined on multiparametric MRI. Dose to prostate, and adjacent structure will remain the same as the current treatment practice. Timing and the delivery of brachytherapy will not change from our current practice
The biological effects of castration on prostate cancers will be studies by administration of degarelix prior to radical prostatectomy. The effects will be studied by analysis of gene expression and immunohistochemistry focusing on markers of proliferation and apoptosis of samples taken at the time of radical prostatectomy (7 days after administration of degarelix). Tumours from patients treated with neo-adjuvant degarelix will be compared with tumours from patients who have not been medically castrated.
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.
