Plasma Epstein-Barr virus DNA for the prediction of treatment response and disease progression in non-keratinizing differentiated nasopharyngeal carcinoma.
Purpose: To explore the failure patterns, outcomes, and treatment response of differentiated non-keratinizing nasopharyngeal carcinoma (DNKC) and to further investigate the role of plasma Epstein-Barr virus (EBV)-DNA in follow-up monitoring, prognostic prediction, and assessment of treatment efficacy in DNKC.
Methods: We retrospectively collected data from patients diagnosed with DNKC from January 2015 to February 2022. The life-table method, Kaplan-Meier survival, and Cox proportional hazards analysis were used for statistical analyses.
Results: A total of 102 patients were included. Of the 77 patients with available EBV-DNA levels, 61 patients (79.2%) had EBV-DNA detectable before treatment. Twenty-seven patients (26.5%) experienced disease recurrence, and 88.9% (24/27) relapsed in the first three years. There were 20 patients who experienced disease recurrence and had pre-treatment EBV-DNA status records. At the time of disease progression, 4 patients initially had undetectable EBV-DNA remained undetectable. Among the 16 patients with initially detectable EBV-DNA, 15 (93.8%) had detectable EBV-DNA. Nodal stage and EBV-DNA levels before treatment were found to be independent prognostic factors for distant metastasis-free survival (DMFS) and disease-free survival (DFS). Those with residual EBV-DNA after induction chemotherapy had significantly inferior DMFS (P = 0.003), DFS (P = 0.006), and overall survival (OS) (P = 0.006) than those without residual EBV-DNA after IC. Those with residual EBV-DNA after radiotherapy had significantly inferior local recurrence-free survival (P = 0.003), DMFS (P < 0.001), DFS (P < 0.001), OS (P < 0.006) than those without residual EBV-DNA after radiotherapy.
Conclusion: Our study highlights the aggressive nature of DNKC, characterized by early recurrence. EBV-DNA levels may serve as a biomarker to monitor treatment response, prognostic prediction, and recurrence surveillance.
期刊介绍：
Infectious Agents and Cancer is an open access, peer-reviewed online journal that encompasses all aspects of basic, clinical, epidemiological and translational research providing an insight into the association between chronic infections and cancer.
The journal welcomes submissions in the pathogen-related cancer areas and other related topics, in particular:
• HPV and anogenital cancers, as well as head and neck cancers;
• EBV and Burkitt lymphoma;
• HCV/HBV and hepatocellular carcinoma as well as lymphoproliferative diseases;
• HHV8 and Kaposi sarcoma;
• HTLV and leukemia;
• Cancers in Low- and Middle-income countries.
The link between infection and cancer has become well established over the past 50 years, and infection-associated cancer contribute up to 16% of cancers in developed countries and 33% in less developed countries.
Preventive vaccines have been developed for only two cancer-causing viruses, highlighting both the opportunity to prevent infection-associated cancers by vaccination and the gaps that remain before vaccines can be developed for other cancer-causing agents. These gaps are due to incomplete understanding of the basic biology, natural history, epidemiology of many of the pathogens that cause cancer, the mechanisms they exploit to cause cancer, and how to interrupt progression to cancer in human populations. Early diagnosis or identification of lesions at high risk of progression represent the current most critical research area of the field supported by recent advances in genomics and proteomics technologies.
