Summary
Brief summary (as posted)
According to a previous study, a cell-free DNA (cfDNA) methylation-based model showed high sensitivity and specificity (80.6% and 98.3%) in blood-based multi-cancer detection. In this way, a multi-center, prospective, single-blind study (THUNDER study) is designed to further validate the performance of the cfDNA methylation-based model for early cancer detection. Blood RNA markers will also be evaluated. The study will enroll approximately 2508 participants, including participants with malignancies and healthy participants.
