The TruScreen™ device showed low sensitivity but high specificity for detecting cervical cancer precursors compared to conventional cytology. Conventional cytology demonstrated a high negative predictive value in this study.
Area of Science:
- Gynecology
- Oncology
- Medical Devices
Background:
- Cervical cancer (CC) is a significant global health issue, particularly affecting women.
- Advanced stages of CC are more prevalent in developing countries.
Purpose of the Study:
- To compare the diagnostic performance of the TruScreen™ opto-electronic device against conventional cytology for cervical cancer screening.
- To determine the sensitivity and specificity of TruScreen™ in identifying cervical intraepithelial lesions.
Main Methods:
- A prospective observational study involving 32 patients at a Dysplasia Clinic.
- Patients underwent evaluation with TruScreen™, conventional cytology, colposcopy, and biopsy if indicated.
- Statistical analysis included sensitivity, specificity, PPV, and NPV, with conventional cytology as the reference standard.
Main Results:
- TruScreen™ exhibited 43% sensitivity and 92% specificity for high-grade intraepithelial lesions.
- Conventional cytology showed a high negative predictive value (NPV) of 85% for the TruScreen™ device.
- The Kappa agreement index between TruScreen™ and colposcopy was 0.70.
Conclusions:
- TruScreen™ demonstrated lower sensitivity but higher specificity compared to conventional cytology.
- Conventional cytology maintained a high negative predictive value for cervical cancer screening.
