Helical tomotherapy for head and neck squamous cell carcinoma: Dosimetric comparison with linear accelerator-based step-and-shoot IMRT

Abstract

Helical Tomotherapy achieved better target coverage with improved OAR sparing as compared to SS IMRT. The significant reduction in mean parotid doses translated into meaningful reduction in NTCP, with potential clinical implications in terms of reduction in Xerostomia and improved quality of life in patients with HNSCC.
