Intensity‐modulated radiation therapy for nasal cavity and paranasal sinus tumors: Experience from a single institute

xlomafota13 shared this article with you from Inoreader Intensity‐modulated radiation therapy for nasal cavity and paranasal sinus tumors: Experience from a single institute Via Head & Neck Abstract Background To assess the efficacy of intensity‐modulated radiation therapy (IMRT) for tumors of the nasal cavity and paranasal sinus (PNS) region. Materials and Methods Two hundred fourteen patients with tumors of the nasal cavity and PNS region treated with curative intent IMRT between 2007 and 2019 were included in this retrospective analysis. Results Fifty‐one (24.1%) received definitive RT/CTRT and 163 (75.9%) received adjuvant RT. Most common histology was squamous cell carcinoma (26.1%) followed by adenoid cystic carcinoma (21.5%). The median follow‐up was 43.5 months. The 5‐year local control (LC), event‐free survival (EFS), and overall survival (OS) for the entire cohort was 66.9%, 59%, and 73.9%, respectively. On univariate analysis treatment with nonsurgical modality, T classification and undifferentiated/poorly differentiated histology were associated with inferior 5‐year LC, EFS, and OS. Four patients had late Grade 3/Grade 4 ocular toxicity. Conclusions IMRT should be the standard of care for tumors of PNS region across all histologies and treatment setting.
