The primary objective of this study is to evaluate the performance of HR-TRUS in detection of prostate cancer lesions relative to whole mount section after radical prostatectomy as the reference.
This phase 2 waitlist-controlled, randomized trial is designed to compare the difference in proliferative index (Ki67) between carbohydrate restricted diet and usual care over a 6 month period in men with prostate cancer who have been placed on Active Surveillance. Eligible patients include men over 18 years old, BMI >25, with their most recently performed biopsy pathologically confirming prostate adenocarcinoma who have been placed on AS. Arms of the trial will be randomized 1:1 in a crossover approach, with Arm A receiving a carb restricted diet over 6 months then SOC and Arm B receiving the waitlist control arm (i.e. SOC then allowed to go on diet after 6 months). Ki67 will be performed on tissue from the most recent biopsy at the beginning of the study and again on tissue obtained in the 6 month SOC biopsy. Every patient will be on the study for 12 months, and the study will continue for approximately 3.5 years.
This study is for patients with metastatic prostate cancer receiving radium-223 as their standard of care therapy. The researchers will collect blood and urine samples from patients before, during and after the radium-223 therapy. The researchers will compare these samples to observe how the treatment has affected different cancer markers.
Background and purpose: The purpose of this study is to investigate the effect of one acute exercise bout on tumor hypoxia in patients with localized prostate cancer undergoing radical prostatectomy. The primary hypothesis is that exercise reduces tumor hypoxia and that the reduction is greater in patients performing one acute high intensity exercise bout compared to no training controls. The investigators have not been able to identify any prior or current randomized trials investigating exercise and tumor hypoxia, and believe that such research is warranted and would be of great importance. Moreover there is a need for studies including biological measurements to allow a full assessment of the effect of exercise on diverse biomarkers and mechanistic pathways, which may influence cancer survival. Subjects: Patients with histologically verified prostate adenocarcinoma scheduled for radical prostatectomy at Urologic Department, Rigshospitalet, Copenhagen, Denmark. Methods: In this randomized controlled pilot study 30 patients with localized prostate cancer undergoing radical prostatectomy will be included and randomized 2:1 to either one single acute High Intensity Interval Training bout or usual care and no training the day prior to radical prostatectomy. All patients will undergo assessment at inclusion (baseline) and the day prior to surgery. Assessment includes: anthropometrics; blood pressure; resting hearth rate; hip and waist circumference, ECG, quality of life by self-report questionnaires; fasting blood sample measuring PSA (prostate specific antigen), cholesterol, triglycerides, insulin, c-peptide, HbA1c, glucose and inflammatory markers. All patients will receive one infusion of pimonidazole hydrochloride (500 mg per m2 body surface in 100 ml 0,9% NaCl intravenously over 20 min) in order to quantify tumor hypoxia by pathological analyses after removal of the prostate. Biological tissue from tumor (primary prostate biopsies) will also be retrieved from the respective local pathological departments and from the perioperative prostate specimen and sent to protocol analyses.
The present study is a phase II, open label, single-center, non-randomized, single-dose study. Twenty subjects in total will be enrolled at Weill Cornell Medical College (WCMC)/ NYPH. The primary objective is to evaluate the ability of 89Zr-Df-IAB2M to detect localized, clinically significant (defined as: ≥ 0.5 cm3 with Gleason pattern ≥ 4) prostate cancer (PCa). After the screening period (up to 28 days), each subject will be scheduled to receive 10 mg infusion of IAB2M conjugated with 2.5 mCi 89Zr-Df. 48-72 hours post-infusion, subjects will undergo a 89Zr-Df-IAB2M PET/CT scan. Images read by a Nuc Med MD reporting: location, SUV and, if possible, size of all areas with abnormal uptake. (they will also undergo a pelvic MRI if they have not obtained an MR image during the screening period or on day of infusion) Patient will undergo radical prostatectomy (1-72 hours after completion of above imaging procedures)
This project aims to evaluate safety and security of patients submitted to minimally invasive radical prostatectomy, who received discharge from hospital in the same day of the surgery (Group I), on the 1st post-surgery day (Group II) and in the 2nd post-surgery day (Group III - control). The specific aims are the evaluation of fail index and factors that influence the permanence in the hospital, the satisfaction of patients, the perception of security of patient, the index of post-discharge complications and the costs related to different times of hospitalization. On randomization, those patients in Group I must match the early hospital discharge criteria defined in the study. Thus, they will be forwarded to "Casa de Apoio Madre Paulina", where will receive nursing care until the next day when, in the morning, will be reevaluated in the ambulatory of urology from Barretos Cancer Hospital. The patients of Group II will be evaluated in the ambulatory in the 2nd post-surgery day, before the discharge. In the Group III (control), the patients will be discharged in the 2nd post-surgery day (routine of Barretos Cancer Hospital). All patients who accept to be enrolled in the study will sign the Consent Term previously the surgery. At the 10th post-surgery day, in the follow-up, it will be applied the Patients' Satisfaction with Mental Health Services Scale (SATIS-BR) questionnaire and an inventory. The data will be descriptive considering average, standard deviation, minimum and maximum value and quartile to the quantitative variables and frequency tables to the qualitative variables. In order to determine the groups' homogeneity, some sociodemographic and clinical characteristics will be compared. To the qualitative variables, it will be used chi-squared test (of Fishers exact test), and to the quantitative variables it will be used variance analysis (or Kruskal-Wallis test). The patients' satisfaction will be measured using SATIS-BR, which consists in three numeric domains (ranging from 1 to 5). The comparison of each domain among the groups will be performed using ANOVA. Then, linear regression will be performed in order to analyze the relationship of the patients' characteristics influencing the satisfaction. The rates of fail, clinical security, security perception and post-discharge complications will be compared among the groups using chi-squared test (of Fisher's exact test). There will be considered the significance level of 5%.
The study is an open-label Phase 1 study of the combination of relacorilant with enzalutamide in patients with metastatic castration resistant prostate cancer (mCRPC).
This study aims to compare the treatment results of HIFU and Radical prosatectomy
This study will test whether oral intake of a dietary supplement called BroccoMax®, which is a special blend of broccoli extract containing a chemical called sulforaphane (hereafter abbreviated as SFN), may result in changes in chemicals that feed prostate cancer. BroccoMax® is available over the counter.
Prostate SBRT is a standard of care treatment for prostate cancer that has not spread to distant metastatic sites. Radiation is delivered to the prostate and seminal vesicles in 5 treatment sessions (fractions). Doses ranging from 35-45 Gy in 5 fractions have demonstrated good outcomes with acceptable toxicity. In this initial study, MRI guided treatment planning and delivery will be used to deliver 7 Gy to the entire prostate and seminal vesicles, with a selective boost of additional 0.5, 1.0, 1.5 or 2 Gy per fraction for total dose of 37.5, 40, 42.5 or 45 Gy to biopsy proven lesions, defined using MRI.
