The ESMO Annual Meeting 2024, held from September 13 to 17 in Barcelona, Spain, showcased the latest breakthroughs in oncology. Among them was a new study from the team led by Academician Jia Fan, Dr. Jian Zhou, and Dr. Xinrong Yang from Zhongshan Hospital, Fudan University, in collaboration with Burning Rock Biotech. The research, which was presented as a poster at the conference, provided preliminary evidence that the methylation and mutation of circulating tumor DNA (ctDNA) play a crucial role in assessing minimal residual disease (MRD) status and predicting recurrence after curative liver cancer surgery. This study offers new strategies and tools for postoperative management of early-stage liver cancer patients. With further refinement and large-scale clinical validation, this method could become an important adjunct in postoperative monitoring, potentially improving patient survival outcomes.
