Clinical Trial Summary

The goal of this multicenter randomized non-inferior study is to compare radiotherapy alone versus concurrent chemoradiotherapy in locally advanced nasopharyngeal carcinoma patients whose EBV DNA drop to undetectable level after one cycle neoadjuvant chemotherapy using GP regimen. The main question it aims to answer is: the omission of concurrent chemotherapy is safe in the relatively good prognostic patients identified by the response of EBV DNA. Participants will be randomized to either radiotherapy alone or the standard treatment concurrent chemoradiotherapy if their EBV DNA decrease to undetectable level post first cycle of neoadjuvant chemotherapy and don't rebound in the second and third cycle.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression-free survival	Defined from date of randomization to date of first documentation of progression or death due to any cause	2 years
Secondary	Overall survival	Defined from date of randomization to date of first documentation of death from any cause or censored at the date of the last follow-up.	2 years
Secondary	Toxicities	Analysis of acute and late adverse events (AEs) are evaluated. Numbers of patients of treatment-related adverse events(acute toxicity) as assessed by CTCAE v5.0.Numbers of patients of late radiation toxicities were assessed using the Radiation Therapy Oncology Group and European Organization for Research and Treatment of Cancer late radiation morbidity scoring scheme.	2 years
Secondary	change of quality of life	QoL scores were assessed for each scale by using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTCQLQ-C30) before induction chemotherapy, before radiotherapy, at the end of radiotherapy, at 3 months after radiotherapy, at 6 months after radiotherapy and 12 months after radiotherapy	1 year
