Filter by:The TEMPOS-GEniToUrinary Group (GETUG) study is a multicenter, medico-economic study comparing brachytherapy to SBRT in low and intermediate risk prostate cancer, particularly focused on the issue of erectile dysfunction. A total of 240 potent patients are randomized in two arms. The experimental arm consists of SBRT delivering 7.25 Gy per fraction, in five fractions, corresponding to a total dose of 36.25 Gy to the prostate. The control arm consists of brachytherapy by Iodine 125 delivering 144 Gy to the prostate. The main objective of this health economics study is to perform a cost-utility analysis of SBRT compared to "standard" Iodine 125 brachytherapy in low-risk prostate cancer, 3 years after treatment. The endpoint is the Incremental Cost-Utility Ratio (ICUR) between SBRT and brachytherapy as primary criterion, expressed in cost per quality adjusted life year (QALY) gained. Cost-effectiveness analyses are performed as secondary objective with Incremental Cost-Effectiveness Ratios (ICERs) expressed as cost per erectile dysfunction avoided and cost per Life Year Gained. A long term evaluation is also performed, including a cost-utility, cost-effectiveness and budget impact analysis at 5 years, a comprehensive assessment of the erectile dysfunction up to 5 years after treatment, an evaluation of acute and late genito-urinary (GU) and Gastro-Intestinal (GI) toxicities, and of quality of life up to 5 years after treatment. Eight patients/year/center are expected to be recruited in 2 years in about twenty participating centers. In total, to our knowledge, this study will be the first health economic evaluation which compares SBRT versus Iodine 125 brachytherapy in low risk and intermediate risk prostate cancer. Both cost-utility and cost-effectiveness analyses will also provide useful and complementary information to decision makers in order (i) to recommend the best strategy to adopt; (ii) to estimate the budget impact on the French National Health Insurance of the generalization of the cost-effective strategy. Finally, this study will allow to assess and compare accurately the erectile dysfunction after both treatment modalities.
This is a randomized control trial testing the effect of walnut supplementation on prostate cancer progression in 50 men with biopsy confirmed prostate cancer and planning to undergo RP. Patients consented to the study will be randomly assigned to either continue their usual diets (control arm) or to the walnut arm for 4-10 weeks depending on the window between their consent date and the date for RP.
Stereotactic body radiation therapy (SBRT) has been employed in the treatment of prostate cancer. Multiple single institution experiences suggest high biochemical control rates with acceptable toxicity in low risk prostate cancer but efficacy data in unfavorable type prostate cancer is less convincing. CyberKnife-SBRT (CK-SBRT) can be used to escalate radiation dose delivery to the prostate while sparing normal tissue.
This phase II trial studies how well atezolizumab works alone or in combination with etrumadenant or tocilizumab in treating men with localized prostate cancer before radical prostatectomy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Androgens can cause the growth of prostate cancer cells. IL-6 is expressed by prostate cancer and within the tumor microenvironment and shown to enhance prostate cancer and disease progression. Treatment with an anti-IL-6 antibody such as tocilizumab may inhibit cancer progression. Giving atezolizumab in combination with etrumadenant or tocilizumab may work better in treating prostate cancer.
With the general acceptance of MRI and technical advances in biopsy technique of the prostate, new questions arise concerning the selection of patients, the approach, the appropriate technique, the lesions to target and the number of biopsies. The purpose of this study is to address these issues in men suspicious of having prostate cancer and without prior biopsies.
This is a 2x2 factorial randomized, multicenter, international, open phase III trial. The primary objective is to evaluate the benefit of acetylsalicylic acid and atorvastatin on overall survival (OS) (main endpoint) for patients with castrate-resistant prostate cancer starting first line treatment for CRPC
The purpose of this study is to determine if there is a difference in intra-abdominal pressure which surgeons use during surgery and post-surgery pain in men who undergo robotic prostate surgery with deep neuromuscular blockade (NMB), compared with moderate NMB.
To determine if holmium laser enucleation of the prostate (HoLEP) for the treatment of lower urinary tract symptoms (LUTS) and/or urinary retention alters the treatment course for patients concurrently diagnosed with prostate cancer.
Progastrin is a pro-hormone that, in physiological conditions, is maturated in gastrin in G cells of the stomach. The role of the gastrin is to stimulate the secretion of gastric acids during digestion. It is also important for the regulation of cell growth of the gastric mucosal. In a healthy person, progastrin is not detectable in the peripheral blood. However, progastrin is abnormally released in the blood of patients with different cancers (colorectal, gastric, ovarian, breast, cervix uterus, melanoma…) The gene GAST coding for progastrin is a direct target gene of the WNT/ß-catenin oncogenic pathway. The activation of this oncogenic pathway is an early event in cancer development. Chronic activation of the WNT/ß-catenin oncogenic pathway occurs in almost all human solid tumors and is a central mechanism in cancer biology that induces cellular proliferation, blocking of differentiation leading to primary tumor growth and metastasis formation. Progastrin measured in the peripheral blood of patients on treatments, could be a new powerful marker for diagnosis and prognosis at different stages.
The investigators intend to use the Second-generation sequencing（NGS）and MiniPDX drug sensitivity models to guide the treatment decision-making for patients who were resistant to abiraterone, enzalutamide or other new second-generation anti-androgenic drugs. In order to develop precise personalized treatment plans for patients and extent their lifetimes.
