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

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.
