Summary
Tactile resonance sensors can detect stiffer prostate cancer (PCa) tumors in whole removed prostates. This technology shows promise for improving intraoperative cancer detection during surgery.
Area of Science:
- Biomedical Engineering
- Surgical Technology
- Oncology
Background:
- Prostate tumors are typically stiffer than surrounding healthy tissue.
- Tactile resonance sensing offers a method for measuring tissue stiffness.
Purpose of the Study:
- To evaluate a tactile resonance sensor system for detecting prostate cancer (PCa) in ex vivo whole prostates.
- To assess the system's ability to identify tumors on and beneath the prostate surface.
Main Methods:
- A tactile resonance sensor system with a rotatable sample holder was employed.
- Studies were conducted using silicone and porcine tissue phantoms, followed by analysis of two resected human prostate glands.
Main Results:
- The sensor successfully detected embedded stiff silicone inclusions 4 mm beneath the surface in phantom models.
- Prostate cancer areas were distinguishable from normal tissue (p < 0.05) when tumors were anteriorly located.
- Small dorsal tumors were not detected.
Conclusions:
- The tactile resonance sensor system can detect prostate cancer in whole, ex vivo prostates, even through the capsule.
- This technology holds potential for intraoperative prostate cancer detection during surgery.
