Filter by:The purpose of this study is to find out the effects of exercise therapy on indicators of prostate cancer in people with low-risk prostate cancer who are on active surveillance. The exercise therapy in this study will be regular home-based walking sessions on a treadmill, and that therapy will be assigned by an exercise physiologist (a medical professional who studies how exercise affects the human body). Some participants in this study will have the assigned exercise therapy, and some participants will participate in their usual exercise routines. Researchers will compare how the assigned exercise therapy and the usual exercise routines affect indicators of prostate cancer in participants. This study will not provide treatment for prostate cancer.
Researchers conducting this study hope to learn about the safety and effectiveness of combining two study drugs, relacorilant and enzalutamide, plus androgen deprivation therapy (ADT), also known as hormone therapy. This study is for individuals who have been diagnosed with advanced, high-risk prostate cancer and standard therapies available to treat your disease have not been effective. Participation in this research will last about 3 years and 9 months.
Doctors leading this study hope to learn about a software that researchers at the University of Chicago have developed to help analyze radiographic images (different techniques for taking images that allow doctors to visualize the body's internal structures) of the prostate. Participation in this research will last about 12 months. There is a one-time MRI and 1-2 biopsies and then the investigator would like to follow the participant's progress.
The goal of this feasibility study is to learn about dose de-escalation in the treatment of men with intermediate risk prostate cancer. The main question it aims to answer is the technical feasibility of treating prostate cancer with toxicity-minimising radiotherapy on an Magnetic Resonance Linear Accelerator (MR-linac). It will also examine gastrointestinal and genitourinary toxicity in the acute and late setting post radiotherapy as well as Prostate-Specific antigen (PSA) control up until 2 years post treatment. Participants will be treated with radiotherapy to the prostate with which will be given in 30Gy in 5 fractions to the whole prostate and 45Gy in 5 fractions to the dominant lesion.
The goal of this research study is to determine whether hormonal therapies used early in the course of prostate cancer could increase the amount of Prostate-Specific Membrane Antigen (PSMA) as detected by PET/CT scans for participants with recurrent prostate cancer. This study will measure PSMA levels using standard PET/CT scans and participants will receive standard-of-care androgen receptor antagonist monotherapy. The names of the treatment interventions involved in this study are: - Androgen receptor antagonist monotherapy. - PSMA PET/CT scan It is expected that about 15 people will take part in this research study. Participation in this research study is expected to last about 4 weeks.
Researchers leading this study hope to learn about the safety of combining the study drug relugolix with another study drug called itraconazole or ritonavir in prostate cancer. This study is for individuals who have advanced prostate cancer and plans to have medical castration (the use of medications or chemicals to lower hormone production in the testicles). Your participation in this research will last up to 1 month. The purpose of this research is to gather information on the safety and effectiveness of relugolix in combination with ritonavir or itraconazole. The goal of this research is to find out if combining two medications (relugolix and itraconazole or relugolix and ritonavir) could possibly lead to using less relugolix, which is an expensive drug.
Background: The current standard treatment of prostate cancer is either surgery or radiation. Typically, this includes either the removal or radiation of the whole prostate gland. Many people now seek out focal therapy options to decrease the side effects of treatment. Until now, several forms of physical destruction with heat (thermal ablation), cold (cryotherapy), sound waves (HIFU), laser (FLA), and electrical energy (IRE). A new type of radiation (SBRT) may be an effective way to cure men of early-stage prostate cancer with fewer side effects than standard treatments. Objective: To see how people with untreated localized prostate cancer will respond to focal therapy with SBRT. Eligibility: People aged 18 years and older with untreated localized prostate cancer (prostate cancer which has not spread outside of the prostate gland). Design: - Participants will undergo screening including blood tests, an MRI, a PSMA PET/CT (18F-DCFPyL), and a biopsy. - Small, non-radioactive, gold seeds about the size of a grain of rice will be placed in and/or around the tumor to help target the radiation treatment. - Radiation (SBRT) will occur in 2 separate sessions about 1 week apart. No sedation is used, these sessions are painless. Each session will take about 1-2 hours. Participants can go home afterwards. - Follow-up will continue for 2 years with repeat scans (MRI and PSMA PET/CT) and blood (PSA) tests. - After two years, a biopsy will be done to understand the impact of this new treatment on prostate cancer.
Prostate Stereotactic ablative body radiotherapy (SABR) is an established technique that delivers radiation in a non-invasive approach for men with prostate cancer. The treatment regimen is given in total of 5 fractions with one treatment per day at every other day or weekly sessions. Ultra-hypofractionated radiotherapy (UHRT) is an emerging monotherapy for localized prostate cancer however, several trials have observed demonstrating superior biochemical control of a two-fraction (HDR) over single-fraction approach. The study aims to compare an experimental shorter course of prostate ultra-hypofractionated radiotherapy (UHRT) that will deliver what is expected to be an equivalent amount of radiation as given in the standard 5 treatment regimen. UHRT is given in 2 treatments with one treatment a week for 2 consecutive weeks.
In localized intermediate- and high-risk prostate cancers (according to the NCCN classification), external radiotherapy delivering a "high" dose (dose equivalent 78-80Gy EQD2, α/ß=1.5) to the entire prostate volume combined with hormonal treatment, if necessary, has shown its benefit in terms of recurrence-free survival and is considered a standard treatment for this indication. Two fractionation modalities (number of sessions) are considered as therapeutic standards, conventional fractionation (39 to 40 sessions of 2 Gy in 8 weeks) and moderate hypo-fractionation (20 sessions of 3 Gy). More recently, phase II and two phase III studies have shown equivalence in terms of safety and efficacy of "extreme hypofractionation" (5 or 6 sessions) for these localized cancers, using stereotactic-type techniques. In view of the current data, this fractionation is considered a therapeutic standard in some countries (notably the USA) and an option in France. Delivering higher doses, beyond 80 GyEQD2 would improve tumor control, as demonstrated by randomized studies using brachytherapy, but at the cost of an increased risk of urinary toxicity. As an alternative to this combination of external radiotherapy and brachytherapy, an innovative approach of external radiotherapy has been developed to increase the therapeutic ratio of patients with localized prostate cancer, based on an escalation of the radiation dose (> 95 GyEQD2) focused on the macroscopic tumor or "dominant intra-prostatic lesion" (DIPL), the area most at risk of local recurrence after conventional dose radiotherapy (3). This external radiotherapy technique consists in performing a conventional dose irradiation on the whole prostate, with at the same time (at each session) a higher dose ("Boost") on the DIPL. This is a modality known as "simultaneous integrated boost" (SIB). The feasibility of simultaneous integrated boost (SIB) on the DIPL has been proven in external radiotherapy using conventional fractionation in the phase III FLAME study and the results in terms of long-term tumor control of this study showed a benefit in terms of biological recurrence-free survival. Feasibility in terms of tolerance has also been established for very hypofractionated regimens (5 sessions), in particular in the HypoFLAME study that followed the above-mentioned study . Multiparametric MRI (mpMRI) is used to identify and delineate the "dominant intra-prostatic lesion" (DIPL), and is the most commonly used modality in clinical studies that have evaluated SIB techniques. However, several studies show that PET imaging, particularly 68Ga-PSMA PET, significantly improves the correlation between the image-defined DIPL and histological data and may improve the likelihood of tumor control. A dosimetric simulation study also showed that dose escalation based on 68Ga-PSMA PET could improve local tumor control with an acceptable level of toxicity . Moreover, 68Ga-PSMA PET could be used to select the patients who could benefit most from this dose escalation, by excluding patients with lymph node or distant metastases.
The objective of this study is to compare the short-term and 1-yr follow-up functional outcomes of retzius-repairing robot-assisted radical prostatectomy (RR-RARP) with retzius-sparing (RS) RARP. This study is a single-centre, single-surgeon and a prospective randomized study.
