Executive summary

This study by the researchers from Taiwan compared the incidence and severity of chronic rhinosinusitis (CRS) in NPC patients who were treated with IMPT (n=53) or VMAT (n=54). Sinus mucosal changes were assessed by MRI and CT imaging and endoscopic scoring system. All patients were followed up for 2 years or more, this study reported that patients in the IMPT group had a significantly lower incidence and decreased severity of sinus mucosa abnormality than those with VMAT. Better and faster recovery of sinonasal function after radiotherapy in the IMPT group was also observed. The authors stated that the clinical benefits of PBT for patients with NPC are becoming increasingly apparent.
