Filter by:The study should evaluate the biological distribution of 99mTc-DB8 in patients with prostate cancer and breast cancer. The primary objective are: 1. To assess the distribution of [99mTc]Tc- DB8 in normal tissues and tumors at different time intervals. 2. To evaluate dosimetry of [99mTc]Tc- DB8. 3. To study the safety and tolerability of the drug [99mTc]Tc- DB8 after a single injection in a diagnostic dosage. The secondary objective are: 1. To compare the obtained [99mTc]Tc- DB8 SPECT imaging results with the data of CT and/or MRI and/or ultrasound examination and immunohistochemical (IHC) studies in prostate cancer and breast cancer patients.
A Study to Investigate the Biological Effects of Saruparib (AZD5305) Alone, Darolutamide Alone, and in Combination Given Prior to Radical Prostatectomy in Men with Newly Diagnosed Prostate Cancer (ASCERTAIN)
Prospective cohort study comparing robot-assisted radical prostatectomy and external beam radiotherapy combined with androgen deprivation therapy for high-risk non-metastatic prostate cancer in terms of health-related quality of life, functional outcomes, cost-effectiveness, progression-free survival and distant metastasis-free survival.
Prostate cancer is the most common non-skin cancer among Veterans and the second leading cause of male cancer death. Current methods of screening men for prostate cancer are inaccurate and cannot identify which men do not have prostate cancer or have low-grade cases that will not cause harm and which men have significant prostate cancer needing treatment. False-positive screening tests can result in unnecessary prostate biopsies for men who do not need them. However, new genetic testing might help identify which men are at highest risk for prostate cancer. This study will examine whether a genetic test helps identify men at risk for significant prostate cancer while helping men who are at low risk for prostate cancer avoid unnecessary biopsies. If this genetic test proves beneficial, it will improve the way that healthcare providers screen male Veterans for prostate cancer.
The purpose of this study is to determine whether a 16-week, home-based, virtually supervised exercise program will slow cancer progression of prostate cancer among Black men with prostate cancer undergoing active surveillance. The name of the study intervention involved in this study is: Aerobic high-intensity interval training (HIIT) (training exercise intervention)
Clinical studies have shown that magnetic resonance imaging-guided transurethral ultrasound ablation (TULSA) of the prostate is safe and effective. In the TULSA procedure, prostate tissue is killed by heating with ultrasound. This clinical trial explores if adding drug therapy with Degarelix before TULSA has the potential to improve further the effectiveness of TULSA in the treatment of localized prostate cancer, especially for patients with more aggressive diseases.
The goal of this clinical trial is to evaluate the impact of a phone call before the simulation CT scan in management of care of patients with prostate cancer.
This study aims to assess the value of ultra-fast MRI sequences in the assessment of prostate cancer, compared to the full multiparametric/biparametric protocol as the clinical standard.
Today, many centers still perform Magnetic Resonance Imaging (MRI) cognitive prostate biopsy. The efficacy of detecting clinically significant prostate cancer, which is thought to be due to the experience of the urologist who performed the sampling and the difference in experience of the radiologists who performed the Multiparametric Prostate Magnetic Resonance (MPMR) evaluation, has been reported between 25% and 34% in the literature. In order to eliminate this reporting and sampling difference, The goal of this interventional study is to compare the effectiveness of Multiparametric Prostate Magnetic Resonance (MPMR) Imaging routinely taken before biopsy with a single-center randomized and prospective study and prostate biopsies to be performed by the same urologist with the mapping technique created by a single genitourinary radiologist working in our center with standard cognitive prostate biopsy and to contribute to the literature Type of study: Clinical trial participant population: Male patients with elevated serum Prostate Specific Antigen (PSA) or indicated prostate biopsy by Magnetic Resonance Imaging (MRI) imaging and underwent Multiparametric Prostate Magnetic Resonance (MPMR) before the procedure Participants will undergo transrectal prostate biopsy with or without mapping, Researches will compare to see if the cancer detection rates differ
Prostate cancer is the second leading cause of cancer death in men. According to estimates by the American Cancer Society Prostate for 2022, about 268,490 men would be diagnosed with prostate cancer and 34,500 would die from the disease. Clinical evolution follows the clinical stages are: localized disease, biochemical recurrence after surgery or radiotherapy, and castration-sensitive or castration-resistant metastatic disease. Localized disease is often classified according to a risk stratification system, which includes assessment of the Gleason score, prostate-specific antigen (PSA) at diagnosis, number of involved fragments per disease at biopsy, and clinical T-staging. Gleason score greater than or equal to 8, PSA greater than or equal to 20 ng/dL at diagnosis, and/or involvement of the prostatic capsule or seminal vesicle are high-risk criteria for biochemical recurrence and later development of metastases, for which the standard treatment is radical prostatectomy or radiotherapy plus androgen deprivation therapy. Prostate-specific membrane antigen (PSMA) is highly expressed on the surface of prostate cancer cells, with relatively low expression in normal tissue. PSMA has been explored as a target in imaging studies using positron emission tomography (PSMA-PET) to reveal occult metastatic disease, as well as a target in the development of PSMA-based treatments with radioligands. According to Hoffman et al., performing PSMA-PET demonstrated greater sensitivity (85% vs. 38%) and specificity (98% vs. 91%), and determined more changes in patient management (28% vs. 15% ) compared to conventional images. Other studies have also demonstrated the greater accuracy of PSMA-based radiotracers compared to conventional images. Finding strategies that increase PSMA expression is a necessity for patients with prostate cancer. According to researchers, high SUVmax values are associated with better outcomes in patients treated with 177-lutetium-PSMA-617. PSMA expression can be rapidly modulated by androgen suppression. The investigators understand that there is great potential to evaluate darolutamide as a PSMA expression enhancer. However, to date there are no prospective data evaluating the effect of ARSI in increasing PSMA expression in localized disease. Here the investigators propose a phase 2 study to investigate the efficacy of a limited course of darolutamide as a PSMA expression enhancer in men with localized prostate cancer according to conventional imaging. PSMA-PET/CT scans will be acquired before and after treatment with darolutamide, as detailed in the protocol. Slides of prostate biopsies and prostatectomies stained with hematoxylin and eosin (H&E) will be reviewed by two pathologists to select the most representative tumor block. Immunohistochemical (IHC) reaction using standard protocols will be performed using an anti-PSMA antibody and intraprostatic anti-androgens. Gene expression analysis will be performed using RNA extracted from biopsies and prostatectomies and evaluated by a panel of over 300 transcripts. For methylation patterns, hematoxylin and eosin (H&E) slides from prostate biopsies and prostatectomies will undergo DNA extraction and evaluation of the methylation profile performed using a kit. It is expected to identify that treatment with darolutamide increases PSMA expression and that the biochemical mechanisms involved can be better evidenced.
