Characterisation of Prostate Lesions Using Transrectal Shear Wave Elastography (SWE) Ultrasound Imaging: A Systematic...

Area of Science:

• Medical Imaging
• Oncology
• Diagnostic Technology

Background:

• Ultrasound-based shear wave elastography (SWE) offers non-invasive assessment of prostate tissue stiffness.
• Prostate cancer (PCa) detection remains a critical area in urological diagnostics.
• Evaluating SWE's efficacy in PCa detection is essential for improving diagnostic strategies.

Purpose of the Study:

• To systematically review and evaluate the diagnostic performance of SWE for prostate cancer detection.
• To compare diagnostic estimates for all PCa versus clinically significant PCa (csPCa).

Main Methods:

• Comprehensive literature search across major medical databases (MEDLINE, EMBASE, Cochrane, etc.).
• Inclusion of studies using histopathology as the reference standard for PCa detection.
• Analysis of diagnostic estimates including sensitivity and specificity.

Main Results:

• 16 studies with 2277 patients were reviewed.
• Pooled sensitivity and specificity for SWE detection of PCa using systematic biopsy were 0.85 and 0.85.
• SWE demonstrated higher pooled sensitivity (0.77) and specificity (0.84) for csPCa detection compared to all PCa when using radical prostatectomy specimens.

Conclusions:

• Shear wave elastography (SWE) is a promising imaging modality for prostate cancer detection.
• SWE shows potential for differentiating clinically significant PCa.
• Further research may solidify SWE's role in routine PCa diagnostics.
