Accuracy of Transvaginal Ultrasonography for Staging of Cervical Cancer Patients: A Meta‐Analysis

ABSTRACT

This review aimed to evaluate accuracy of transvaginal ultrasonography (TVUS) in detecting parametrial invasion, stromal invasion, and metastasis of lymph nodes in patients with cervical cancer. We performed bivariate meta‐analysis using STATA 14.2, calculating pooled sensitivity, specificity, diagnostic odds ratio (DOR), and likelihood ratios (LR+ and LR−). In total, 18 studies were included. TVUS showed pooled sensitivities of 82%, 82%, and 75% and specificities of 92%, 78%, and 96% for detecting parametrial invasion, stromal invasion, and lymph node metastasis, respectively. TVUS is reliable tool for confirming parametrial invasion and lymph node metastasis in cervical cancer, particularly, in resource‐limited settings.
