Cancer in a drop: Liquid biopsy highlights from the American Society of Clinical Oncology (ASCO) 2025 annual congress

Over the past decade, liquid biopsy has progressively expanded its role in oncology, supported by mounting evidence demonstrating an increasing number of clinical applications. At the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, liquid biopsy emerged as a central theme across multiple sessions, with more than 700 abstracts, investigating the clinical utility of liquid biopsy across a wide range of tumor types and disease stages. Applications presented included cancer screening, minimal residual disease (MRD) detection, management of metastatic disease, and potential use for matching patients to clinical trials. This editorial, authored on the behalf of the Young Committee of the International Society of Liquid Biopsy (ISLB) highlights the result of selected studies, grouped by tumor type.
