Cover Story: Ovarian cancer (OC) remains one of the most lethal cancers among women due to the lack of accurate and sensitive screening tools, combined with ambiguous symptoms. Such a tool exists for cervical cancer in the Papanicolaou (Pap) test, which greatly reduces this cancer’s mortality rates. Due to the frequency and non-invasive nature of this test, as well as previous evidence of OC cells in Pap tests, this study aims to evaluate the practicality of using such tests as biospecimens for OC screening-related metabolomics. This feasibility study includes the analysis of 29 Pap test samples via mass spectrometry analysis, with the goal of establishing a relative metabolomic profile for healthy women over the age of 50, rendering it the first investigation to utilize residual Pap test samples as biospecimens in a metabolomics workflow.
