Active clinical trials for "Prostatic Neoplasms"

The objective of this project is to offer a very innovative solution for measuring temperature variations in MRI on the prostate. Multiparametric prostate MRI can detect target lesions, on which targeted biopsies are then performed. The use of a temperature mapping on the prostate in MRI would make it possible to evaluate a focal treatment of the prostate by laser under MRI guidance

The objectives of this study are to evaluate the feasibility and safety of [99mTc]Tc-PSMA-T4 in the diagnosis and treatment planning of prostate cancer.

A [18]F-PSMA-1007 PET/CT or PET/MRI scan are nuclear medicine tests used to create pictures of the whole body that may show where cells that express Prostate-Specific Membrane Antigen (PSMA) are found. PSMA is a transmembrane protein that is overexpressed in the majority of prostate cancers. PSMA imaging utilizes this overexpression, by binding on the transmembrane receptor and internalization in the cancer cells. The internalized isotope can then be imaged with the use of a PET/CT or PET/MRI scanner and show where cancer cells may be present in the body. This imaging modality has been shown to be superior to conventional imaging, such as bone scan and CT, in the detection of prostate cancer tumors. The purpose of this study is to: 1) assess the clinical impact of a [18]F-PSMA-1007 scan on patient management plans; 2) assess the diagnostic effectiveness of a [18]F-PSMA-1007 scan in participants with known or suspected metastatic prostate cancer, as compared to standard of care CT chest, abdomen, pelvis and bone scan; 3) evaluate the safety of [18]F-PSMA-1007; and 4) assess potential correlations of PSMA level of uptake in certain tumors with cancer biologic markers such as PSA and Gleason score.

This research study is designed to determine if targeted Magnetic Resonance Imaging (MRI) Ultrasound (US) fusion biopsy is better than the standard of care ultrasound guided biopsy alone in diagnosing subjects with clinically significant prostate cancer with MRI visible lesions. This study will consist of comparing the standard of care (ultrasound guided prostate biopsy) with the protocol biopsy which consists of an ultrasound guided prostate biopsy and a MRI/US fusion tracked prostate biopsy.

To investigate the radioactive uptake of [Al 18 F]PSMA137 in PCa patients, and evaluate the ability of [Al 18 F]PSMA137 to detect PSMA overexpression in PCa patients (especially those with recurrent or advanced PCa).To provide an approach for screening patients high expression of PSMA, efficacy monitoring, drug resistance and early warning of recurrence and metastasis to achieve the individualized antitumor treatment of targeted drugs.

Prostate-specific membrane antigen (PSMA)-targeted PET imaging with 68Ga-labeled compounds is able to provide superior sensitivity and specificity to detect primary prostate tumor and its metastases, like the widely studied 68Ga-PSMA-617. This pilot study was prospectively designed to evaluate the early dynamic distribution of 68Ga-P16-093, a novel radiopharmaceutical targeting PSMA, which was compared with 68Ga-PSMA-617 in the same group of prostate cancer patients.

The purpose of this study is to develop and evaluate a Magnetic Resonance (MR) fusion 3D Ultrasound (US) guided Low dose rate (LDR) brachytherapy technique that significantly spares prostatic neurovascular bundles (a bundle of nerves and vessels that run beside the prostate) and penile bulb (base of the penis), while still trying to effectively treat the prostate cancer.

The project aims at assessing the role of radio-guided surgery in the detection of lymph node invasion (LNI) in prostate cancer (PCa) patients undergoing radical prostatectomy (RP) by using an intraoperative gamma probe and a radioactive labelled PSMA ligand (99mTc-PSMA-I&S). We hypothesize that 99mTc-PSMA-I&S radio-guided surgery (99mTc-PSMA-RGS) might assist physicians in the identification of patients with LNI candidate for an extended pelvic lymph node dissection (ePLND). Overall, 100 men with a LNI risk >5% according to the Briganti nomogram will be submitted to 68Ga-PSMA PET/MRI followed by 99mTc-PSMA-RGS and ePLND. The aims are 1) to assess the safety and tolerability of 99mTc-PSMA-I&S; 2) to assess the accuracy of 99mTc-PSMA-RGS in the identification of LNI compared to available clinical tools and to molecular imaging (i.e., 68Ga-PSMA PET/MRI); 3) to assess whether 99mTc-PSMA-RGS would allow for the identification of positive nodes outside the standard ePLND template.

This prospective clinical trial (PRostate Imaging using Mri +/- contrast Enhancement (PRIME)) aims to assess whether biparametric MRI (bpMRI) is non-inferior to multiparametric mpMRI (mpMRI) in the detection of clinically significant prostate cancer. This means that we are comparing MRI scans that requires injection of IV contrast (the current standard practice) versus MRI scans that can be performed without IV contrast in the detection of prostate cancer.

Adult male patients with high-risk, localized prostate cancer and planning to undergo radiation therapy (RT) with androgen deprivation therapy (ADT) will undergo an advanced Magnetic Resonance Imaging (MRI) examination called Restriction Spectrum Imaging (RSI-MRI) to evaluate whether RSI-MRI can predict treatment response.
