View on ClinicalTrials.gov →
Summary
The above studies show that most of the supportive evidence for the reduction of toxicity and improvement of efficacy of proton therapy for recurrent Nasopharyngeal carcinoma(NPC) comes from various observational and retrospective studies, lacking high-level evidence-based medical evidence. The conduct of this study will explore the safety and efficacy of intensity-modulated proton radiotherapy for recurrent NPC and provide more high-quality evidence-based medical evidence for proton therapy of recurrent cancer.
