This study from Japan reported clinical outcomes of patients with locally advanced nasal cavity and paranasal sinus (NPSCC) treated with postoperative PBT or definitive PBT. The median follow-up period was 4.4 years. The 4-year OS, PFS, and LC rates were 58%, 43% and 58% for all patients. The authors concluded that PBT gave favorable outcomes in multimodal treatment for resectable locally advanced NPSCC, including surgery followed by postoperative PBT and radical PBT with concurrent chemotherapy.
