Brief Summary
Endemic nasopharyngeal carcinoma (NPC) is invariably associated with Epstein-barr virus (EBV) infection. Plasma EBV DAN detected by polymerase chain reaction (PCR)-based assays can provide important informations of disease screening, disease relapse, and risks classification. In this study, the investigators will explore the impact of serial plasma EBV DNA during chemotherapy and radiotherapy on initial tumor response and long-term survival in patients with non-metastatic nasopharyngeal carcinoma

Outcome Measures
Primary Outcomes (1)
Progression-free survival
Progression-free survival is calculated from the date of diagnosis of NPC to the date of progression of NPC or the date of death from any cause, whichever comes earlier.
3 years
Secondary Outcomes (4)
overall survival
3 years
Distant metastasis-free survival
3 years
locoregional failure-free survival
3 years
EBV DNA clearance rate
during the first month
Study Arms (1)
observational cohort
Patients enrolled in this observational cohort would have regular blood taking for EBV DNA examination at baseline, after every cycle of chemotherapy, every week during radiotherapy, and 1-3 months after chemo-radiotherapy until EBV DNA becomes undetectable for at least two times.
Interventions
Parameters analyzed will include (1) the changing pattern of plasma EBV DNA concentrations during chemotherapy and radiotherapy (2) half-life values (t1/2) of plasma EBV DNA clearance rate
Eligibility Criteria
Patients with histologically confirmed, non-metastatic, previously untreated nasopharyngeal carcinoma (NPC) will be invited to join this study.
You may qualify if:
- Patients with newly histologically confirmed non-keratinizing carcinoma (according to WHO histological type)
- No evidence of distant metastasis (M0)
- Receive standard radical treatment
- Not exhibiting overt psychopathology, and willing to participate and written informed consent was obtained
You may not qualify if:
- WHO type keratinizing squamous cell carcinoma or basaloid squamous cell carcinoma.
- Treatment with palliative intent
- Previous chemotherapy or radiotherapy (except non-melanomatous skin cancers outside the intended RT treatment volume)
- Severe intercurrent disease
