Filter by:This phase II trial studies how well antiandrogen therapy, abiraterone acetate, and prednisone with or without neutron radiation therapy work in treating patients with prostate cancer. Hormone therapy such as antiandrogen therapy may fight prostate cancer by blocking the production and interfering with the action of hormones. Abiraterone acetate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Neutron radiation therapy uses high energy neutrons to kill tumor cells and shrink tumors. It is not yet known whether antiandrogen therapy, abiraterone acetate, and prednisone with or without neutron radiation therapy may work better in treating patients with prostate cancer.
This phase II trial studies how well hyperpolarized carbon C 13 pyruvate magnetic resonance spectroscopic imaging works in predicting treatment response in patients with prostate cancer. Hyperpolarized carbon C 13 pyruvate magnetic resonance spectroscopic imaging may help to accurately predict how prostate cancer patients will respond to standard therapy (abiraterone and apalutamide).
This phase II trial studies how well hypofractionated radiation therapy works in treating participants with prostate cancer high-risk features following radical prostatectomy. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects.
Aim: The aim of the study is to compare the efficacy with SBRT and moderate hypo-fractionation in high risk and node positive prostate cancer PRIMARY STUDY OBJECTIVES: To assess whether extreme hypo-fractionation with SBRT in high risk prostate cancer is non inferior to moderately hypo-fractionated standard radiotherapy STUDY DESIGN: Two arm, Prospective Randomized Trial with a non-inferiority design TREATMENT REGIMEN: Arm 1-[standard arm] Moderate hypo-fractionated RT, total dose of 66-68 Gray(Gy) in 25# to the primary over 5 weeks, with treatment being delivered daily. All patients irrespective of nodal status will receive a dose of 50 Gy in 25# to the pelvic nodes.Boost to gross nodal disease will be considered based on the response to hormonal therapy to a dose of 60-66 Gy/25# as a simultaneous integrated boost (SIB). An option of equivalent biological dose using 60-62.5 Gy in 20# may be allowed for multi-centric accrual in the future. Arm 2 -[Experimental Arm] Extreme hypo-fractionation with SBRT,course of 5 fractions of radiation; each of size 7-7.25 Gy. The total dose will be 35-36.5 Gy. All patients irrespective of nodal status will receive a dose of 25 Gy in 5 # to the pelvic nodes. The 5 treatments will be scheduled to be delivered alternate day over approximately 7-10 days. An option of equivalent biological dose using 35-36.5 Gy in 5 weekly fractions may be allowed for multicentric accrual in the future. RECRUITMENT TARGET: 464 total (232 patients experimental arm and 232 patients standard arm) recruitment over 6 years, with a non-fixed follow up period and a uniform accrual rate. PRIMARY ENDPOINT To assess the 5 year Biochemical Failure free Survival (BFFS) between the two arms. Follow-up At 3-6 weeks from end of radiotherapy, followed by 3-6 monthly for the first two years and 6 monthly thereafter.
Feasibility trial of twice high dose radiotherapy using Tomotherapy in patients with organ confined Prostate Cancer histologically proven. The study involves 2 steps: A) Assessment of safety as proportion of patients with acute ≥G3 Genito-urinary (GU) and Gastro-intestinal (GI) side effects on the first 16 enrolled patients; B) evaluation of primary and secondary objectives on overall patients.
This phase II trial studies how well testosterone (enanthate or cypionate) and olaparib work in treating patients with prostate cancer that has progressed despite hormonal therapy. Hormonal therapy, such as leuprolide, may lessen the amount of male sex hormones made by the body. In patients that have developed progressive cancer in spite of standard hormonal treatment (i.e. castration-resistant prostate cancer), administering testosterone may result in regression of tumors by causing DNA damage in cancer cells that have adapted to low testosterone conditions. Olaparib may stop the growth of tumor cells by blocking some of the enzymes involved in repairing DNA damage. Therefore, giving testosterone and olaparib together may work better in treating castration-resistant prostate cancer by generating DNA damage that the cancer cell is unable to repair.
The purpose of this study is to evaluate safety and short-term oncological efficacy of the NanoKnife Irreversible Electroporation System for localised prostate cancer. Irreversible electroporation (IRE) is the method of focal treatment for prostate cancer, which is already proven by FDA as method of the surgical ablation of soft tissue. It has not received clearance for the therapy or treatment of any specific disease or condition.
This is a prospective data collection of men who are electing to undergo prostate hemi-gland cryoablation. The purpose of this observational research study is to investigate the localized treatment of prostate cancer using hemi-gland cryoablation. UCLA patients undergoing hemi-gland cryoablation are a unique cohort compared to prior research because all patients at UCLA have had a pre-treatment multi-parametric MRI and Ultrasound fusion targeted biopsy; they will be followed in a similar fashion. This results in more precise assessment of a target region of cancer for ablation which may, in turn, result in improved clinical outcomes.
This study provides fluorine F 18 DCFPyL positron emission tomography/computed tomography (PET/CT) to participants with prostate cancer that has come back. Diagnostic procedures, such as fluorine F 18 DCFPyL PET/CT, may help find and diagnose prostate cancer and find out how far the disease has spread.
