Liver cancer, often referred to as the “silent killer,” is frequently diagnosed at an advanced stage. Current screening methods such as alpha-fetoprotein (AFP) testing and ultrasound lack sufficient sensitivity and specificity. Therefore, there is an urgent need for more efficient, accurate, and cost-effective screening tools. At the 2024 ESMO conference, former President of the Korean Surgical Society and Professor at Inje University Haeundae Paik Hospital, Wang Hee-Jung, presented a novel method based on digital PCR detection of circulating tumor DNA methylation markers, demonstrating promising sensitivity and specificity results. Oncology Frontier invited Dr. Tian Yang from the Third Affiliated Hospital of Naval Medical University to provide insights on this study.
