The blind brush sampling does not require the guidance of endoscopy, which is favorable for implementation and dissemination in the community. This study explored methylation markers for nasopharyngeal carcinoma (NPC) at both Epstein\u2013Barr virus (EBV) and its host genome levels, aiming to construct a blind brushing diagnostic method.\n            <jats:bold>Methods:<\/jats:bold>\n            EBV DNA capture and methylation sequencing and GEO Illumina 450K methylation array data were used respectively for the discovery of EBV and host methylation markers. The diagnostic method was built in training cohort (\n            <jats:italic>n<\/jats:italic>\n            = 347) and validated in an independent validation cohort (\n            <jats:italic>n<\/jats:italic>\n            = 155).\n            <jats:bold>Results:<\/jats:bold>\n            A total of 1 EBV methylation marker (BILF2) and 6 host methylation markers (ITGA4, IMPA2, ITPKB, PI9, AMIGO2, and VAV3) were identified. Both EBV and host methylation markers were almost exclusively detected in NPC samples, with negligible detection in control samples. In validation cohort, the diagnostic method that included only the EBV BILF2 marker showed a sensitivity and specificity of 80.22% and 98.44%, respectively. When combining the EBV-derived marker BILF2 with the host-derived marker IMPA2, the diagnostic method\u2019s sensitivity increased to 84.62%, while the specificity remained unchanged (IDI = 4.4%,\n            <jats:italic>P<\/jats:italic>\n            = 0.0419).\n            <jats:bold>Conclusion:<\/jats:bold>\n            Overall, the blind nasopharyngeal brushing diagnostic method, combining EBV and host methylation markers, showed great potential in NPC detection and could promote its application in nonclinical screening of NPC.\n          <\/jats:p>","DOI":"10.34133\/research.0475","type":"journal-article","created":{"date-parts":[[2024,8,28]],"date-time":"2024-08-28T15:43:29Z","timestamp":1724859809000},"update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark_01","source":"Crossref","is-referenced-by-count":6,"title":["Blind Brush Biopsy: Quantification of Epstein\u2013Barr Virus and Its Host DNA Methylation in the Detection of Nasopharyngeal Carcinoma"],"prefix":"10.34133","volume":"7","author":[{"given":"Caoli","family":"Tang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Oncology in South China, Guangdong Key Laboratory of Nasopharyngeal Carcinoma Diagnosis and Therapy, Guangdong Provincial Clinical Research Center for Cancer, Sun Yat-sen University Cancer Center, Guangzhou 510060, P.
