(Nasdaq: GH), a leading precision oncology company, will present a total of 14 abstracts with its research collaborators from multiple studies demonstrating the value of its tissue-free liquid biopsy tests at the 2025 San Antonio Breast Cancer Symposium (SABCS), taking place Dec. 9–12, 2025.\n\nOral presentations will highlight results generated with Guardant Reveal, the company’s tissue-free test for detecting minimal residual disease (MRD) and Guardant360 Liquid, the company’s comprehensive multiomic profiling test, both leveraging Guardant’s proprietary epigenomic technology powered by the Guardant Infinity Smart Platform. Collectively, these studies demonstrate how blood-based testing can uncover risk, guide treatment selection, and influence long-term patient management across the breast cancer continuum, from early-stage disease through metastatic settings.\n\nGuardant’s MRD presentations reinforce the value of tissue-free circulating tumor DNA (ctDNA) testing for both neoadjuvant treatment response assessment and post-treatment surveillance in early-stage breast cancer. In a retrospective analysis of HER2-positive patients, ctDNA measured with Guardant Reveal demonstrated strong prognostic significance in the neoadjuvant setting, showing a correlation with pathological complete response and three-year invasive disease-free survival. In an independent study of triple-negative breast cancer patients, Guardant Reveal accurately predicted relapse risk and detected ctDNA more frequently and earlier than orthogonal methods.\n\nTogether, these findings demonstrate the validity of Guardant Reveal as a reliable approach for ctDNA detection and monitoring in both neoadjuvant and surveillance settings.\n\n“Breast cancer care increasingly depends on understanding tumor biology at every stage of disease, and Guardant’s data continues to reaffirm the growing value of multiomic liquid biopsy as a powerful, non-invasive tool to equip providers with the data necessary to tailor therapy and treatment,” said Dr. Craig Eagle, Chief Medical Officer at Guardant Health. “We look forward to sharing our findings demonstrati...
