Evaluation of Diagnostic Performance of a Detection Kit for Epstein-Barr Virus C Promoter Methylation in Nasopharyngeal Carcinoma
This clinical study aims to evaluate the diagnostic performance of a new Epstein-Barr virus (EBV) C promoter methylation detection kit. All participants will undergo a series of diagnostic tests including VCA-IgA, EBNA1-IgA, and EBV-DNA assays. Additionally, nasopharyngeal swabs will be analyzed for EBV C promoter methylation. Confirmatory biopsy will be performed on all patients to establish a definitive diagnosis. This comprehensive approach seeks to assess the effectiveness of the methylation detection kit in a clinical setting.
⁃ Participants who meet the following Article 1 and also meet one of Articles 2 to 6 can be enrolled:
• Understand, sign, and date the informed consent document to participate in the study
• Display one or more symptoms or signs indicative of nasopharyngeal carcinoma
• Test positive for EBV antibodies or EBV DNA
• Be diagnosed with other head and neck carcinomas
• Be diagnosed with malignancies associated with EBV infection
• Require differential diagnosis from nasopharyngeal carcinoma during endoscopic or other imaging examinations
• Fulfill any additional conditions deemed appropriate by the investigator for inclusion in this study
