| Popis: | Hypofractionated radiation therapy is not commonly used in head and neck cancers (HNC) due to increased toxicity observed in historical cohorts. This study reviews our institutional experience using hypofractionated intensity modulated radiation therapy (H-IMRT) for HNC.A retrospective cohort study of 56 patients with HNC treated with H-IMRT with ≥50 Gy in 20 fractions was conducted. The primary outcomes were acute and late toxicity.Two-year locoregional control was 87% and median overall survival was 46 months. There were no acute or late grade 4 or 5 toxicities. Acute grade 2 and 3 toxicity was seen in 79% (N=44) and 25% (N=14), respectively. Late grade 2 toxicity was seen in 9% (N=5). No patients required the placement of a feeding tube or tracheostomy.H-IMRT for the definitive or post-operative treatment of HNC using ≥50 Gy in 20 fractions appears safe and well tolerated with modest toxicity. |
