Combining High-frequency Micro-ultrasound and Multiparametric MRI Target Biopsy for Detecting Prostate Cancer

Официальное название

Combining High-frequency Micro-ultrasound Target Biopsy and Multiparametric MRI Target Biopsy - Does it Increase the Detection Rate of Clinically Significant Prostate Cancer? A Prospective, Interventional, Single Centre, Randomized Controlled Trial

Обзор

\*\*Study Goal:\*\* The purpose of this clinical trial is to determine if combining high-frequency micro-ultrasound with multiparametric MRI biopsy and a systematic biopsy can better detect clinically significant prostate cancer compared to current standard methods. This study is aimed at men who may have prostate cancer. \*\*Main Questions the Study Aims to Answer:\*\* 1. Does the combination of new biopsy methods detect more clinically significant prostate cancers than the current standard method? 2. Does the new method not increase the detection of less serious forms of cancer beyond what the standard method detects? \*\*Participation in the Study:\*\* Participants in this study will undergo the following procedures: * A high-frequency micro-ultrasound examination of the prostate. * A multiparametric MRI-targeted biopsy of the prostate. * A systematic biopsy of the prostate. \*\*Comparison Group:\*\* Researchers will compare the new combination method with the current standard method to see if the new approach is more effective. \*\*Participants will:\*\* * Undergo several exams and biopsies depending on the results of previous tests. * Attend regular follow-up appointments to monitor potential side effects and evaluate prostate health. * Record their experiences and any symptoms in a diary.

Подробное описание

The primary objective of this study is (i) to demonstrate that the combination of highfrequency micro-ultrasound target biopsy, multiparametric MRI target biopsy, and systematic biopsy detects more clinically significant prostate cancer (\>= ISUP 2) than multiparametric MRI target biopsy and systematic biopsy alone (current standard of care).

The secondary objective of this study is (ii) to demonstrate that the combination of high frequency micro-ultrasound target biopsy, multiparametric MRI target biopsy, and systematic biopsy does not detect more clinically insignificant prostate cancer (ISUP 1) than multiparametric MRI target biopsy and systematic biopsy alone (current standard of care).

The third objective of this study is (iii) to demonstrate that the combination of highfrequency micro-ultrasound target biopsy and multiparametric MRI target biopsy does not detect less clinically significant prostate cancer (\>= ISUP 2) than multiparametric MRI target biopsy and systematic biopsy (current standard of care).

The fourth objective of this study is (iv) to demonstrate that the combination of highfrequency micro-ultrasound target biopsy and multiparametric MRI target biopsy detects less clinically insignificant prostate cancer (ISUP 1) than the combination of multiparametric MRI target biopsy and systematic biopsy (current standard of care).

Вмешательства

• Устройство High-frequency micro-ultrasound target biopsy
  1. High-frequency micro-ultrasound (transrectal ultrasound, 29 Hz, ExactVu) of the prostate. If suspicious lesions (PRIMUS \>= 3) other than those already detected in multiparametric MRI are found, target biopsy will be performed. Maximum of four cores per lesion. 2. Multiparametric MRI target biopsy (PI-RADS \>= 3) of the prostate (transrectal ultrasound, 29 Hz, ExactVu). Maximum of four cores per lesion. 3. Systematic biopsy (twelve cores) of the prostate
• Устройство conventional Multiparametric MRT target biopsy
  1. Multiparametric MRT target biopsy (PI-RADS \>= 3) of the prostate (conventional transrectal ultrasound, 8-10 Hz). Maximum of four cores per lesion. 2. Systematic biopsy (twelve cores) of the prostate
