Comparing radiotherapy alone to concurrent chemoradiotherapy for nasopharyngeal carcinoma patients with undetectable EBV DNA after chemotherapy

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter randomized non-inferior study aims to evaluate the safety of omitting concurrent chemotherapy in patients with locally advanced nasopharyngeal carcinoma who have achieved undetectable levels of EBV DNA after one cycle of neoadjuvant chemotherapy. Participants will be randomly assigned to receive either radiotherapy alone or the standard concurrent chemoradiotherapy. The study focuses on patients whose EBV DNA levels do not rebound during subsequent cycles of chemotherapy, thereby identifying a potentially lower-risk group. The goal is to determine if radiotherapy alone is a safe and effective treatment option for these patients.

2. Suffered from other malignant tumors (except the cure of basal cell carcinoma or uterine cervical carcinoma in situ) previously.
3. Receiving radiotherapy or chemotherapy or targeted therapy previously
4. Women of child-bearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the preparative chemotherapy on the fetus or infant.
