An article titled, “Prognostic values of HE4 expression in patients with cancer: a metaanalysis”, was recently published in the journal, Cancer Management and Research, detailing a study conducted by Dai et al.1 This study aims to validate and estimate the effectiveness of HE4 as a prognostic marker in cancer. We commend the authors for the study’s focus on all types of cancers, as well as the associated subgroup analysis detailing the results for individual cancer types and population groups. This study is valuable as a guidepost for informing future research on HE4 as a prognostic biomarker to predict the cancer patients’ clinical outcomes. However, there are a few points that require to be addressed regarding the study conducted.
