Translating Liquid Biopsy into Practice- The Promise and Challenges of Circulating Tumor Cells in Ovarian and Lung Cancer Management.
Review in Biomarker insights, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The increasing mortality from ovarian and lung cancers worldwide is largely due to late diagnosis and therapeutic resistance. Conventional biomarkers such as CA125 and CYFRA 21-1 lack the sensitivity or the specificity for monitoring real time disease progression or therapeutic response. This has prompted researchers to work on the development of relevant biomarkers that are minimally invasive for cancer diagnosis, prognosis and for therapeutic stratification. As such, liquid biopsies, which analyze tumor-derived components circulating in the blood including circulating tumor cells (CTCs), which are shed from primary or metastatic tumors into the bloodstream have emerged as a promising approach for detecting such cancers. This review critically analyzes the diagnostic and prognostic significance of CTCs in ovarian and lung cancers, highlighting technological advances, molecular characterization, and translational challenges associated with their clinical application. It briefly discusses the clinical utility of some biomarkers from liquid biopsies used in the diagnosis, prognosis as well as monitoring of ovarian and lung cancers with their detection methods. It highlights some of the relevant studies conducted in the field and finally it provides insights on the future of liquid biopsies. An extensive literature review analyzing papers between 2008 and 2026 was conducted using PubMed, Scopus, and Web of Science databases, that evaluated CTC detection methods, molecular profiling, and clinical outcomes in ovarian and lung cancer patients. Current literature reports that CTC enumeration and molecular characterization can provide significant insights into disease progression, therapeutic resistance and predict survival outcomes.
