Active clinical trials for "Prostatic Neoplasms"

Prostate cancer is the third most common cause of cancer death in men. Most patients with localized prostate cancer will be cured with surgery or radiation therapy, but up to 35% of patients will have their prostate cancer return.Current conventional imaging modalities have limitations particularly at low prostate specific antigen levels. This study proposes to use 68Ga-HTK03149 Dynamic Whole Body (DWB) Positron Emission Tomography / Magnetic Resonance Imaging (PET/MRI) scans which targets prostate-specific membrane antigens (PSMA) to detect where in the body the prostate cancer has recurred.

The main purpose of this study is to reveal the effectiveness of the Knack maneuver and lifestyle recommendations program to be given in addition to the pelvic floor muscle training (PFMT) program, which has been proven to be effective in individuals with urinary incontinence symptoms after prostatectomy. This study is a prospective, controlled, randomized clinical trial. The study includes an 8-week pelvic floor muscle training, Knack maneuver and lifestyle recommendations. In summary, it is stated in the literature that PFMT and lifestyle recommendations are beneficial in the treatment of urinary incontinence (UI). However, although there is evidence of the effectiveness of the Knack maneuver in stress UI in women, there is no evidence of the Knack maneuver in urinary incontinence after prostatectomy. On the other hand, the literature on the effect of lifestyle recommendations after prostatectomy is very limited. Therefore, the aim of this study is to reveal the effectiveness of the Knack maneuver and lifestyle recommendations program, which will be given in addition to the PFMT program, which has been demonstrated in individuals with UI complaints after radical prostatectomy, in a randomized controlled design.

To evaluate whether the efficacy of the abiraterone acetate tablets (I) is comparable to that of the ZYTIGA®) by comparing the serum testosterone concentrations on Day 9 and/or Day 10 after oral administration of the two formulations in patients with metastatic castration-resistant prostate cancer (mCRPC).

The aim of this study is to provide clinical evidence to determine if Whole Body Magnetic Resonance Imaging (WBMRI) with a novel technique called diffusion-weighted imaging (DWI) can improve current treatment for APC patients, allowing for early identification of disease progression or treatment response, hence facilitating clinical decision-making and leading to improvement in patient care. The IDT study includes two retrospective analyses and a single centre prospective observational study for APC patients.

This is an open-label, multicenter, dose escalation and expansion Phase 1 study of SHR7280 in adult patients with hormone sensitive prostate cancer.

Robotic assisted laparoscopic prostatectomy (RALP) is the standard treatment for prostate cancer, due to the benefits of decreased blood loss and length of stay.The procedure involves removing a man's prostate using a minimally invasive robotic approach under the guidance of a surgeon. In order to gain sufficient access, carbon dioxide (CO2) is used to fill the surgical space in a process termed insufflation. Carbon dioxide is a mainstay in laparoscopic procedures because it is cost-effective, noncombustible and readily excreted via the respiratory system in healthy patients. Insufflation with CO2, however, has been linked to post-operative referred pain secondary to peritoneal acidosis.This acidosis is suspected to be due to the formation of carbonic acid from the CO2 insufflation.Peritoneal acidosis, and its associated post-operative referred pain, may not be adequately treated with the current standard pain control regimen.

The primary aim of this large prospective study consists of exploring the correlation among Volumetric and Radiomic parameters extracted from staging PSMA PET/CT Imaging versus conventional baseline clinical biochemical data, conventional imaging and the aggressiveness of the tumor based on the post-surgical-Gleason Score (GS) in patients with intermediate/high risk prostate cancer (PCa). Secondarily, Volumetric and Radiomic features extracted from the same PET images will be compared with the amount of the Circulating Tumor Cells (CTCs), with the expression of specific receptors on CTCs surface, Possible mutations encoding androgen receptors (AR) on CTCs surface, and with PSMA density on primary tumor cells provided by the Immunohistochemistry method (IHC) applied on post-surgical histological samples. According to PET images, Volumes of interest (VOI) encompassing the whole prostate with foci of PSMA uptake suspected for PCa will be drawn to extract semiquantitative and radiomic PET features. The association between PSMA PET radiomics and CTCs molecular and genomic panel at staging could potentially lead to a more personalized and more effective therapeutic chances.

In recent years, the clinical research of immunotherapy including PD-1 antibody and CD3 bispecific antibody in prostate cancer has been increasing day by day. The comparison with the analysis results of cancer tissues of advanced patients has important guiding significance for the application of these new treatment methods. In a retrospective study, investigators plan to perform multi-omics analysis (including whole exome, RNAseq), immune cell characterization, and biopsy samples from prostate cancer primary biopsy, ADT neoadjuvant, and CRPC biopsy samples in the biobank. Protein and prostate cancer-specific antigen expression were analyzed by immunohistochemistry. The following questions are answered by comparing samples from different treatment stages in early and advanced stages: 1. Whether the immune environment becomes "cold" in the advanced stage; 2. Which immune cell populations have changed significantly; 3. Is the inhibitory immune microenvironment related to genes Mutations or suppressive immune cell populations.

This research will study a custom device developed to detect if any prostate cancer tissue is left behind when the prostate is removed. This device is called an Electrical Impedance Imaging (EII) probe.

This is an observational, open, single-arm, prospective, staged entry（based on Fleming's Group-Sequential Design） clinical study The Goal is to evaluate the feasibility and clinical value of direct robot assisted laparoscopic radical prostatectomy without prostate biopsy in patients with high clinical suspicion of prostate cancer based on a prostate MRI PI-RADS score of ≥4 and the PSMA PET/CT positive criteria. The Primary endpoint is positive pathological diagnosis of prostate cancer after direct radical prostatectomy without prostate biopsy. The question addressed is whether the feasibility of biopsy-free radical prostatectomy could be scientifically and rationally derived based on Fleming's Group-Sequential design.
