Endometrial sampling tests for the diagnosis of endometrial carcinoma: a protocol of a diagnostic test accuracy systematic review

Background: Endometrial cancer ranks as the most common gynecological cancer. An accurate detection can dramatically improve patient relevant outcomes.Objectives: To determine the diagnostic accuracy of different endometrial sampling methods for detecting endometrial carcinoma and its precursors.Search strategy: we will search the Cochrane library, Pubmed/MEDLINE, Web of Science, and Scopus. We will search references of relevant studies.Selection criteria: We will include diagnostic test accuracy studies if women had an endometrial sampling followed by verification with histopathology in hysterectomy specimens. The primary target is endometrial carcinoma.Data collection and analysis: Two authors will independently screen studies, extract data, and assess methodological quality. We will use bivariate diagnostic random-effects meta-analysis.Results: This is a protocol of a diagnostic test accuracy systematic review.Conclusions: Evidence will aid in making well-informed decisions for diagnosing endometrial carcinoma. Implications for research will be outlined for future studies.
