Diagnostic accuracy of transvaginal ultrasound examination for local staging of cervical cancer: a systematic review and meta-analysis

Yu Tian, Hong Luo


Aim: Transvaginal ultrasonography (TVUS) has shown varying results in the staging of cervical cancer patients around the world. Hence, the current review was done to assess the diagnostic accuracy of TVUS for identifying parametrial, stromal invasion and lymph node metastasis among cervical cancer patients.

Material and methods: We conducted a systematic search for all studies reporting the diagnostic accuracy of TVUS for staging of cervical cancer in the databases of PubMed Central, MEDLINE, EMBASE, MEDLINE, SCOPUS and Cochrane library from inception till March 2021. Meta-analysis was performed using STATA software “midas” package.

Results: Eleven studies with 760 patients were included. The pooled sensitivity and specificity of TVUS for diagnosing parametrial invasion were 62% (95% CI, 40-80) and 91% (95% CI, 79-97), for stromal invasion were 84% (95% CI, 77-90) and 80% (95% CI, 61-91), for lymph node metastasis were 52% (95% CI, 8-93) and 95% (95% CI, 68-99). There was significant heterogeneity found with all the outcomes with significant chi-square test and I2 statistic >75%.

Conclusion: TVUS has limited applicability and use as a screening or diagnostic tool for local staging of cervical cancer patients. Further reviews comparing multiple non-invasive imaging modalities are required to pick the best tool for local staging of cervical cancer.
