Executive summary
This study from China reported treatment results of 26 patients with nasopharyngeal adenoid cystic carcinoma (NACC) treated with IMPT. With a median follow-up of 46.95 months, this study reported a total of 91.3% of the patients achieved complete remission of gross tumors at 1 year after PBRT. The 3- and 4-year OS and LC rates were 100% and 91.7%, and 95.8% and 87.8%, respectively. A grade 4 decrease in visual acuity was observed in one patient with orbital apex invasion. No late grade 3 or 5 toxicity was observed.
