Urinary and Prostate Microbiotes and Prostate Cancer
Prostatic NeoplasmIn recent decades, the cancer process has been linked to microbial infections, particularly in gastric and Helicobacter pylori cancers, but also in cervical cancers promoted by exposure to Human papilloma virus (HPV). More recently, it has been shown that bacteria in the intestinal microbiota could promote the development of colorectal cancer by modulating the inflammatory response within the intestinal mucosa. Among male cancers, prostate cancer is the leading cause in France with 54,000 new cases per year. In addition, the dogma that urine is sterile has been broken and the notion of the presence of a "urinary microbiota" in asymptomatic patients is now accepted. While the risk factors associated with this cancer have not yet been clearly elucidated, recent evidence in the literature agrees that chronic inflammation associated with prostate infection plays a key role as a factor that may promote the development and/or progression of prostate cancer. Most recently, a study shows for the first time that a group of 6 bacteria is found significantly higher in the urine of patients with prostate cancer than in patients with prostate adenoma. Interestingly, clinical microbiology studies conducted at the bacteriology laboratory of the University Hospital of Nice on A. schaalii have shown that this species is also isolated in the urine of patients with bladder and prostate cancers. The investigators wish to study the association of the 6 bacterial species mentioned above with prostate cancer by directly analyzing the prostate tissue of patients with this condition. the staff will carry out a multicenter case-control study by recruiting a total of 260 patients in 4 centres (Nice coordinating centre, Marseille, Tours and Nîmes): 130 in the prostate cancer group and 130 in the prostate adenoma control group. This project is a research involving the human person of category 2. The innovative aspect of the work consists in detecting and quantifying in situ in the prostate tissue the presence of these 6 bacterial species per culture and per PCR in real time, comparing the prostate microbiota in terms of richness and diversity between cancer patients and those without cancer. Ultimately, this study opens up exciting prospects with the possibility of determining a microbial origin of prostate cancer and considering antibiotic therapy for anti-cancer purposes such as H. pylori and gastric cancer.
Molecular Stratification Profiling Protocol in Metastatic Castration Resistant Prostate Cancer (mCRPC)...
Metastatic Prostate CancerCastration-resistant Prostate CancerThis study is a prospective, observational, molecular stratification profiling study. Patients with mCRPC who have received at least one standard treatment for mCRPC will be approached to participate in MAESTRO. Patients must have archival tumour available and be willing to undergo a fresh tumour biopsy for molecular analyses. Tumour tissue (archival and fresh), research blood samples and saliva will be sent to the central laboratory for analysis to identify molecular aberrations through targeted or broader molecular analyses (e.g. exome, transcriptome) and orthogonal assays (e.g. immunohistochemistry; digital droplet PCR). When the results are available, depending on patients choice, the results will be discussed. If significant results are indicated, patients will be recommended to have follow up with a cancer geneticist to discuss the implications of these results for their personal and family's health. There is a safety follow up 30 days after collection of study biopsy or blood samples. Patients will also be followed up for overall survival and subsequent anticancer treatment every 6 monthly via medical notes or telephone calls.
Comparison H-FIRE and Laparoscopic RP in Treating Men With Localized Prostate Cancer
Prostate CancerTreatmentThis trial is comparing the functional and oncological outcomes in treating men with prostate cancer between high-frequency irreversible electroporation and laparoscopic radical prostatectomy.
Marker Driven Selection of Patients for Prostate Biopsy and Management
PSAElevated PSA1 moreThe purpose of this research study is to determine if the interpretation of multiparametric MRI (mpMRI) with an algorithm called habitat risk score (HRS) in combination with a panel of blood and urine biomarkers is more effective at detecting prostate cancer than standard of care interpretation of mpMRI with the Prostate Imaging Reporting and Data System (PIRADS).
Fostering Shared Decision-making About Prostate Cancer Screening Among Clinicians and African American...
Prostate CancerThis behavioral clinical trial assesses the efficacy of a educational intervention to increase shared decision making about prostate-specific antigen (PSA)-based screening for prostate cancer among African American males. Half of participants will receive a multimedia educational intervention, while the other half will receive usual care.
Serial MRI Scans During Radiation Therapy
GlioblastomaEsophageal Cancer6 moreThis is a phase 1 study to determine the feasibility and utility of using serial magnetic resonance imaging (MRI) to assess treatment response during and after radiation therapy (standard of care cancer treatment) for participants with advanced esophageal cancer, glioblastoma, prostate cancer, vulvar cancer or pediatric glioma. The research study procedures include three MRI scans (one before, one during, and one after standard of care cancer radiation therapy) for participants with advanced esophageal cancer, glioblastoma, prostate cancer, vulvar cancer or pediatric glioma. The research study procedures include: Screening for eligibility Three MRI scans
African Cancer Genome: GMD
Breast CancerProstate CancerThe goal of this study is to develop a comprehensive characterization of genetic and molecular drivers of breast and prostate cancer in individuals of African ancestry. The study is conducted by the African Caribbean Cancer Consortium (AC3) and involves the recruitment of patients from nine international AC3 research sites in the Bahamas, Barbados, Benin, Burkina Faso, Haiti, Jamaica, Kenya, Namibia, and Trinidad and Tobago, and the US. The main questions are to: molecularly characterize genomic changes in the African Cancer genomes of the breast and prostate and identify the effects of social determinants of health and lifestyle factors on mutational landscape. Black individuals that have been diagnosed with pathologically confirmed prostate or breast cancer will be included. Detailed social determinants of health survey, blood and archived FFPE tissues will be collected. (Tier 1) All patient tissues will be subject to IHC for receptor status (ER, AR, PR Her2/neu). All patients with available germline DNA from blood will receive genetic screening using a Commercial gene panel testing. (Tier 2) Patient samples with a negative genetic screening will be subject to whole exome sequencing or banked for later RNA or methylation sequencing.
A Study of Enzalutamide Plus the Glucocorticoid Receptor Antagonist Relacorilant Versus Placebo...
Prostate CancerProstate AdenocarcinomaResearchers 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.
SLPI for Prostate Cancer
Prostate CancerProstatic NeoplasmExploratory study of SLPI expression in human prostate cancer patients This is a no-profit exploratory study about the expression of SLPI in human prostate cancer patients that will enroll about 200 patients admitted for suspect prostate cancer to Careggi University Hospital. We will verify whether an increase SLPI levels in the sera may serve as biomarker of cancer progression.
