NCT06733350
This phase IV trial studies the effects of testosterone replacement therapy (TRT) on treatment outcomes in hypogonadal men with prostate cancer that has not spread to other parts of the body (localized) and who are on active surveillance (AS). AS in prostate cancer involves closely watching the patient's condition through regular physical exams and blood tests, but not giving treatment unless there are changes in test results. It can be a practical alternative to treatment in localized prostate cancer. Hypogonadal men have low testosterone associated with symptoms such as low libido and erectile problems. TRT can be used to treat hypogonadism by increasing testosterone levels, which may improve associated symptoms. TRT is often not used in men with prostate cancer due to concerns it may lead to the cancer growing or spreading. This may lead hypogonadal men to have a poor quality of life or to discontinue AS. TRT may improve treatment and quality of life outcomes in hypogonadal men with localized prostate cancer on active surveillance.
NCT06200974
This is an observational single-center trial for patients with localized prostate cancer suitable for High Dose Rate (HDR) brachytherapy as monotherapy. This study takes a multi-omics approach to study the mechanism of action of HDR brachytherapy through metabolomics, immunological, transcriptomics, and spectroscopic profiling. The results of this study will clarify the optimal dose for HDR prostate brachytherapy by documenting the dose-response relationship seen in the changing tumor metabolites after HDR brachytherapy and investigate the immunogenicity of HDR brachytherapy.
NCT02600156
The primary purpose of this study is to evaluate the feasibility and safety of MRI-guided focal laser ablation (Laser-Induced Interstitial Thermal Therapy, LITT) to treat low-risk native prostate cancer.
NCT07054346
There is evidence that Actinium-225 Prostate-Specific Membrane Antigen (225Ac-PSMA) has a potentially higher level of efficacy than 177 Lutetium Prostate-Specific Membrane Antigen (177Lu-PSMA) as a radioligand therapy. This single center, pilot study will compare differences in the mechanisms of actinium-225 and lutetium-177 radioligand therapies (RLT) in participants with high or very high risk localized or locoregional prostate cancer planning on undergoing a prostatectomy.
NCT05877144
This phase I clinical trial studies how well low intensity shockwave therapy (LiSWT) improves erectile function in patients who have had nerve-sparing radical prostatectomy (NS-RP), a type of surgery that attempts to save the nerves near the tissues being removed, for prostate cancer. Erectile dysfunction (ED) is a known side effect of the radical prostatectomy procedure. The low intensity shockwave therapy delivers painless electrotherapy pulse to increase blood flow and supply, activation of tissues and wound healing. Using LiSWT after NS-PRP may improve erectile function in men with prostate cancer.
NCT05936736
Patients with prostate cancer who are candidates for stereotactic radiotherapy to the prostate and seminal vesicles will undergo staging exams, which will include prostate specific membrane antigen (PSMA) positron emission tomography-computed tomography (PET-CT). If the PET scan is negative and the uroflowmetry is acceptable, the patients will perform the treatment, after fiducial implantation, simulation CT and magnetic resonance (MR), in a single fraction, delivered with a high-dose-rate (HDR)-like urethral sparing technique. In 70 patients, acute and late toxicity, biochemical control, overall survival, cancer specific-survival, and quality of life (through specific questionnaires) will be evaluated.
NCT02526368
This pilot clinical trial studies how well magnetic resonance spectroscopic imaging (MRSI) with hyperpolarized carbon 13 (13C) pyruvate alone or in combination with 13C 15N2 Urea works in finding prostate cancer that exhibits poorly differentiated or undifferentiated cells (high-grade) and that is restricted to the site of origin, without evidence of spread (localized) in patients undergoing radical prostatectomy. Diagnostic procedures, such as MRSI with hyperpolarized carbon (13C) pyruvate, may aid in the diagnosis of prostate cancer and in discriminating high-grade from low-grade prostate cancer and benign adjacent prostate tissue
