Filter by:This study collects urine and stool samples to determine the ability to identify changes in the microbiome (bacteria, fungi, and viruses that live in the gut and urine) of patients with prostate cancer during androgen deprivation therapy and radiation therapy. Radiation therapy has the potential to harm the genitourinary area or the bowel, causing a feeling of urgency or increased inflammation in the area. The radiation therapy is designed to not irradiate the bowel and bladder areas, but there is still some radiation exposure. The gut microbiome has been associated with differences in inflammation as well as producing molecules that influence healing. The purpose of this study is to see whether the microbiome may contribute to the healing of the organs exposed to radiation. Information learned from this study may help researchers discover a new risk factor that could be manipulated to improve the quality of life in patients with prostate cancer.
Radiotherapy has an important role in the treatment of prostate cancer both as curative treatment and postoperative or salvage ones. Several studies demonstrated a significant reduction of lymphocytes during RT but there are only a few studies monitoring these cells in the treatment of prostate cancer. This study will enroll 50 patients with hystologically proven prostate cancer who will undergo to radiotherapy according to Institutional protocols. This study aims to evaluate the effect of RT on immuno-regulatory B, NK, T, B and T lymphocyte subpopulations (Breg and Treg) and plasma cells, quantitative / qualitative changes,their correlations with the clinical course of the disease and acute and late toxicity. In parallel, using multicolor panels (12 colors) we will evaluate the expression of inhibitory checkpoints and TGFβ signaling. The final objective is to identify new therapeutic targets to be combined with RT.
The management of localized prostate cancer remains controversial because of a risk of over diagnosis and over treatment. Focal therapy represents an approach to improve the therapeutic ratio of prostate cancer treatments. Focal therapy has been developed as minimally invasive procedure with the aim of providing equivalent oncological safety, reduced toxicity and improved functional outcomes. Multiparametric (mp) MRI Imaging may provide a reliable mean of monitoring for disease recurrence, and has been suggested as the most accurate imaging tool currently available for systematic detection of recurrence, pre-biopsy and preoperative mapping for an eventual salvage therapy. However, question about the performance of MRI and targeted biopsy in monitoring and defining successful therapy and follow up has been poorly evaluated. Modalities (standard biopsy, ablation zone biopsy vs targeted biopsy) and number of biopsies to be performed, depending on the results of MRI, remains unanswered due to a lack of available data. We hypothesize that the combination of MpMRI of the prostate with subsequent targeted biopsy (TB) may improve detection of prostate cancer and may therefore improve the follow-up of men after focal therapy (FT) to better identify patients that need a salvage treatment and when.
This is a descriptive, observational, prospective, open-ended, registry utilising electronic data capture to collect information on the outcomes of men treated with prostate specific-membrane antigen (PSMA) theranostics.
This study evaluates how new magnetic resonance imaging (MRI) and artificial intelligence techniques improve the image quality and quantitative information for future prostate MRI exams in patients with suspicious of confirmed prostate cancer. The MRI and artificial intelligence techniques developed in this study may improve the accuracy in diagnosing prostate cancer in the future using less invasive techniques than what is currently used.
This study aims to evaluate the use of a prostate cancer specific predisposition genetic panel test in men with / at high risk of prostate cancer. The genetic test will analyse men's DNA samples for the presence of mutations in rare genes as well as common genetic variation to provide men with information about their risk of prostate cancer. This study will evaluate the clinical impact of the test on risk assessment and clinical management in terms of screening and treatment.
This is an open-label, phase II umbrella trial assessing the anti-tumor activity of enfortumab alone and in combination with other anti-cancer agents in subjects with metastatic castration-resistant prostate cancer. The trial will open to enrollment in Cohort A, enfortumab monotherapy. Additional cohorts may be added as new drug combinations are identified.
The purpose of this study is to assess the safety and effectiveness of radiation therapy with hormone therapy (ADT) and chemotherapy as an investigational study treatment for prostate cancer. This is a phase 2 study to deliver focal radiation with pulsed systemic therapy of Abiraterone, ADT and Lynparza (olaparib) in men with castration sensitive oligometastatic prostate cancer.
The PROMPT study aims to routinely implement genomic pre-sorting of metastatic castration-resistant prostate cancer (mCRPC) patients for personalized treatment (e.g. immuno-, PARP inhibitors, or platinum-therapy). The investigators hypothesize that, by doing this early in the disease course (before exhausting standard of care options), it will improve treatment planning, patient outcome, quality of life, and reduce costs.
In France, prostate cancer is the most common cancer in men over 50 years of age (nearly 50,000 new cases per year) and is the second most common cause of cancer death in men (approximately 9,000 deaths per year). Although mortality has been declining since the end of the 1990s (about 7%/year), about 30 to 35% of them will have a biological recurrence. Accurate assessment of local, regional and distant spread of the disease is therefore needed to design optimal personalised care for each patient, either curative or palliative. Currently, in France, recommended disease assessment includes bone scintigraphy and Abdomino-Pelvic Magnetic Resonance Imaging. However, conventional imaging has limited performance with regard to lymph node extension. Node dissection is the best way to assess node status. Currently, no imaging exam allows this level of accuracy. Recently, molecular imaging has emerged as a promising tool to improve the initial extensional assessment of prostate cancer. Prostate-specific membrane antigen (PSMA) is a transmembrane glycoprotein, specific to the prostate, which is over-expressed on the surface of prostate cancer cells. Recent studies of PSMA PET/CT as part of the initial extension assessment of prostate cancer report superior diagnostic performance in terms of sensitivity and specificity compared to conventional tests, as well as an impact of PSMA PET/CT on patient management.
