Filter by:The goal of this clinical trial is to compare two dose schedules of stereotactic radiation therapy in patients with localized prostate cancer. Historically, external beam radiation to treat localized prostate cancer was given in small treatments over a period of multiple weeks. Recent studies have shown that with newer technologies and better understanding of how prostate cancer responds to radiation, the same effective dose can be given in as few as 5 treatments. This study is comparing this newer standard course of 5 treatments with an even shorter course of just 2 treatments. The dose for the 2 treatments is based on a form of internal radiation called brachytherapy, but in this study, that dose will be given using external radiation, without the need for invasive procedures. In order to make sure that the radiation therapy is given in a way that minimizes the risk of side effects to the surrounding organs, including the rectum and bladder, prior to radiation a hydrogel material will be inserted behind the prostate in order to distance the rectum further from the prostate gland, and small gold markers will be inserted into the prostate to decrease any possible movement during treatment. The main questions are whether 2-treatment radiation is tolerated as well and is as effective at treating prostate cancer, compared to the standard 5-treatment course of radiation.
In this study, participants with different types of advanced solid tumors who failed standard treatments will be treated with XNW5004 in combination with KEYTRUDA® (pembrolizumab) .
The purpose of this study is to determine the feasibility and effects of an adapted Exercising Together, a partnered resistance training program, on the physical and mental health of prostate cancer survivors and their informal caregiver. The Exercising Together program is designed to promote teamwork during supervised group exercise classes delivered remotely through videoconferencing software. The intervention period will be 3-months with a 3-month follow-up.
This study evaluates the efficacy, anti-tumor effect, and immunogenicity of neoadjuvant enoblituzumab given before radical prostatectomy. Patients will be randomized to enoblituzumab for a total of 12 weeks beginning 84 days before radical prostatectomy or standard of care arms.
In this study, 18F-Florastamin PET/CT will be performed in patients with at least intermediate risk prostate cancer, to assess the diagnostic performance and safety of 18F-Florastamin PET/CT imaging. This study will first carry out the pilot study (including pharmacokinetics and radiation dosimetry).
The goal of this phase 2 multicenter randomized controlled trial is to study the accuracy of second generation prostate specific membrane antigen (PSMA) positron emission tomography (PET; utilizing 18F-PSMA-1007) compared to standard of care multiparametric MRI and MRI targeted-prostate biopsy for staging in patients diagnosed with unilateral prostate cancer who are eligible for focal therapy. The main question it aims to answer is: Can PSMA PET improve diagnostic accuracy for the primary staging of Prostate Cancer for patients undergoing focal therapy thereby reducing residual and recurrence disease? Participants who are eligible by current standard of care diagnostic workup will undergo 1:1 randomization to PSMA PET scan or no further imaging. Those diagnosed with bilateral disease by PSMA PET will be ineligible for focal therapy and be referred for radical therapy. Men with unilateral disease on PSMA PET and those randomized to no further imaging will then undergo focal therapy. All men undergoing focal therapy will receive PSMA PET, MRI, and combined targeted and systematic biopsy 12 months after ablation. The primary outcome will be the detection of Gleason Grade Group 2 or higher prostate cancer in men 12 months after hemigland ablation.
PROMED is a prospective, single center translational multiple cohort study to investigate the association of prostate medication and gut microbiota. The main aim is to investigate how prostate hormonal therapy (5-ARI, ADT) affects gut microbiota composition. Aalso study metabolic characteristics in the gut and systemic circulation in men with different medications will be studied. In addition, the effect of gut microbiota on patient's response to medications will be investigated. The medicines used in the study to treat benign prostate hyperplasia are dutasteride and finasteride and a combination of dutasteride and tamsulosin. LHRH antagonist degarelix is used as a medication to treat patients with cancer. The dosages of 5-ARI medication: dutasteride 0,5mg x1 or finasteride 5mg x1 or combination of dutasteride and tamsulosin 0,5/0,4mg x1. The starting dose of LHRH antagonist degarelix is 120mgx2 and the maintenance dose is 80mgx1. The medication for PCa is planned according to the protocol but so that each subject receives degarelix at the beginning of treatment and one month after initiation. Thereafter, the medication is continued according to the clinician's assessment. The study is carried out in Turku University Hospital and University of Turku.
Following the major technological and scientific advances in external radiotherapy in recent decades, thanks to the use of three-dimensional conformal techniques combined with intensity modulation, image-guided radiotherapy has enabled radiotherapists to increase doses without increasing sequelae and complications, giving rise to the term "dose escalation". Following multiple dose-escalation clinical trials showing better biological control of PSA, the results of the latest phase 3 FLAME trial incorporated the notion of intraprostatic boost in relation to the primary prostate lesion, considered to be the preferred site of neoplastic recurrence in prostate cancer. This leads to the first question, which concerns the identification of the dominant lesion and its precise delimitation. This last point is subject to variation between operators. A retrospective cohort from the Finistère region will therefore be used to develop a number of study points relating to : inter-operator contour variability - Factors influencing contour - Impact of contour variability on dosimetry - Automatic segmentation
This study is a single-center registry study collecting clinical data regarding the treatment of PSMA-positive metastatic castration-resistant prostate cancer treated with PSMA radionuclide therapy per the treating physician's discretion. Clinical data from candidates for or who undergo the PSMA procedure at Methodist Dallas Medical Center from August 2022 to August 2027 will be collected after discharge and patients will undergo clinical follow-up per the treating physician's discretion.
The purpose of the study is to evaluate the incidence of surgery-related complications between Day 0 and Day 30.
