Induction Chemotherapy Response-Guided Radiation for EBV-Associated Nasopharyngeal Carcinoma
This clinical trial tests the effect of induction chemotherapy response-guided radiation (de-escalated intensity-modulated radiation therapy \[IMRT\]) compared to standard IMRT in patients with Epstein-Barr virus (EBV)-associated nasopharyngeal cancer. Intensity-modulated radiation therapy (IMRT) is an advanced form of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles. This type of radiation therapy reduces the damage to healthy tissue near the tum
