Comparison of Multi-omics Models for Early Nasopharyngeal Carcinoma Screening: CfDNA Methylation, EBV DNA, and Serological Double-antibodies Detection

This study focus on nasopharyngeal carcinoma, a cancer type with Chinese characteristics, analyze the early screening detection performance of nasopharyngeal carcinoma in the multi-cancer early screening model, and compare the performance differences among multi-omics models such as nasopharyngeal carcinoma-specific DNA methylation and fragmentome in the multi-cancer early screening model and the clinically routinely conducted Epstein-Barr virus (EBV) nucleic acid quantification (EBV DNA) test and serological double antibody (double antibodies of EBNA1-IgA and VCA-IgA) test. It suggests that compared with EBV DNA quantification and double antibody tests, in patients with nasopharyngeal carcinoma, multi-omics models such as DNA methylation can avoid false negatives, improve sensitivity, and increase the detection rate of early-stage nasopharyngeal carcinoma; in patients without nasopharyngeal carcinoma, multi-omics models such as DNA methylation can avoid false positives, improve specificity, and avoid unnecessary over-diagnosis.
