Diagnostic Accuracy of EBV C Promoter Methylation Kit in Nasopharyngeal Carcinoma

June 24, 2024 updated by: Hai-Qiang Mai,MD,PhD, Sun Yat-sen University

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sensitivity of Epstein-Barr Virus C Promoter Methylation in Diagnosing Nasopharyngeal Carcinoma
Time Frame: From enrollment to final diagnosis, up to 4 weeks
Measure the sensitivity of Epstein-Barr Virus (EBV) C Promoter Methylation as a diagnostic marker for Nasopharyngeal Carcinoma (NPC). Sensitivity will be calculated as the proportion of true positive cases (patients correctly identified with NPC) out of the total number of actual NPC cases.
From enrollment to final diagnosis, up to 4 weeks
Specificity of Epstein-Barr Virus C Promoter Methylation in Diagnosing Nasopharyngeal Carcinoma
Time Frame: From enrollment to final diagnosis, up to 4 weeks
Measure the specificity of Epstein-Barr Virus (EBV) C Promoter Methylation as a diagnostic marker for Nasopharyngeal Carcinoma (NPC). Specificity will be calculated as the proportion of true negative cases (patients correctly identified without NPC) out of the total number of actual non-NPC cases.
From enrollment to final diagnosis, up to 4 weeks
Kappa Value of Epstein-Barr Virus C Promoter Methylation in Diagnosing Nasopharyngeal Carcinoma
Time Frame: From enrollment to final diagnosis, up to 4 weeks
Evaluate the agreement between Epstein-Barr Virus (EBV) C Promoter Methylation and the gold standard diagnostic methods for Nasopharyngeal Carcinoma (NPC) using the Kappa statistic. The Kappa value will indicate the consistency and reliability of EBV C Promoter Methylation as a diagnostic tool compared to established diagnostic criteria.
From enrollment to final diagnosis, up to 4 weeks
Concordance Analysis of Test Reagents and Sequencing Methods in EBV C Promoter Methylation Detection
Time Frame: From enrollment to final diagnosis, up to 4 weeks
This measure evaluates the positive, negative, and total concordance rates, as well as the Kappa Value, between test reagents and two established sequencing techniques-Sanger sequencing and pyrosequencing-for detecting Epstein-Barr virus C promoter methylation. The accuracy of these detection methods is assessed by comparing their results to those obtained through the widely used and mature technologies of Sanger dideoxy chain termination and pyrosequencing, often considered the "gold standards" for gene sequence analysis. This study aims to evaluate the reliability and accuracy of the test reagents in identifying methylation of the EBV C promoter, using these established sequencing benchmarks.
From enrollment to final diagnosis, up to 4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Concordance Rates between EBV-Related Antibodies and EBV C Promoter Methylation
Time Frame: From enrollment to final diagnosis, up to 4 weeks
This outcome measures the agreement rates between EBV C promoter methylation and EBV-related antibodies in the diagnosis of nasopharyngeal carcinoma without a gold standard for comparison. It includes an evaluation of the positive concordance rates, negative concordance rates, and Kappa value, which might reflect limited conclusiveness but offer insight into the relative alignment of these diagnostic tests. This will help ascertain their comparative reliability and diagnostic utility in a real-world setting.
From enrollment to final diagnosis, up to 4 weeks
Concordance Rates between EBV-DNA and EBV C Promoter Methylation
Time Frame: From enrollment to final diagnosis, up to 4 weeks
This outcome measures the agreement rates between EBV C promoter methylation and EBV-DNA in the diagnosis of nasopharyngeal carcinoma without a gold standard for comparison. It includes an evaluation of the positive concordance rates, negative concordance rates, and Kappa value, which might reflect limited conclusiveness but offer insight into the relative alignment of these diagnostic tests. This will help ascertain their comparative reliability and diagnostic utility in a real-world setting.
From enrollment to final diagnosis, up to 4 weeks

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Dynamics of EBV C Promoter Methylation Before and After Nasopharyngeal Carcinoma Treatment
Time Frame: From enrollment to the end of treatment at 6 months, up to 1 years
During follow-up consultations 1 to 6 months post-discharge, nasopharyngeal swabs will be collected to observe the dynamics of EBV C promoter methylation before and after treatment for nasopharyngeal carcinoma
From enrollment to the end of treatment at 6 months, up to 1 years
