Learning curve on prostate fusion biopsies: key insights

Area of Science:

• Urology
• Radiology
• Oncology

Background:

• MRI-guided prostate biopsies enhance cancer detection accuracy.
• Image fusion (IF) techniques show promise but have a learning curve.
• Evaluating operator experience is key to optimizing IF biopsy outcomes.

Purpose of the Study:

• Assess the impact of operator experience on prostate biopsy outcomes.
• Analyze cancer detection rates, procedure times, and accuracy using the HITACHI ultrasound system.
• Determine the learning curve associated with MRI-guided fusion biopsies.

Main Methods:

• 148 patients underwent mpMRI and targeted biopsies (Sept 2016 - Mar 2020).
• Patients grouped into Early (1-50), Intermediate (51-100), and Late (101-148) experience phases.
• Biopsy outcomes analyzed across phases to evaluate learning curve effects.

Main Results:

• Clinically significant cancer detection rate increased from 12% (Early) to 25% (Late).
• Overall positivity rose from 30% to 45%; procedure time decreased from 45 to 30 minutes.
• Sensitivity for detecting significant cancer improved from 60% to 85% with experience.

Conclusions:

• Operator experience is critical for improving prostate biopsy outcomes with IF techniques.
• Increased proficiency leads to higher cancer detection rates and procedural efficiency.
• Adequate training is essential to maximize the benefits of fusion biopsy for prostate cancer diagnosis.
