To evaluate the role of transvaginal ultrasound (TVUS) for diagnosing cervical invasion in the preoperative assessment of endometrial carcinoma.
A search for studies evaluating the role of TVUS for assessing cervical invasion in endometrial carcinoma from January 1990 to December 2016 was performed in the PubMed/MEDLINE, Web of Science, www.ClinicalTrials.gov, and www.who.int/trialsearchdatabases. The quality of the studies was evaluated by the Quality Assessment of Diagnostic Accuracy Studies 2.
We identified 211 citations. Ultimately, 17 studies comprising 1751 women were included. The mean prevalence of cervical invasion was 16.3%. The risk of bias was high in 7 studies for the domains "patient selection" and "index test," whereas it was considered low for the "reference test" domain.
Overall, the pooled estimated sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio of TVUS for detecting cervical invasion were 63% (95% confidence interval [CI], 51%-74%), 91% (95% CI, 87%-94%), 10.2 (95% CI, 5.7-18.3), and 0.38 (95% CI, 0.28-0.53), respectively. Heterogeneity was high for both sensitivity and specificity.
Transvaginal ultrasound has acceptable diagnostic performance for detecting cervical invasion in women with endometrial carcinoma.
