Key Points

To compare dosimetry and radiation pneumonitis outcomes between tomotherapy and IMRT in thoracic cancer patients.
Conducted a controlled trial.
Compared dosimetry between tomotherapy and IMRT.
Monitored incidence of radiation pneumonitis in both treatment groups.
Tomotherapy provided superior dose distribution to planning target volumes (PTVs).
Both treatment methods had comparable rates of radiation pneumonitis.

Abstract

Compared with fixed-field IMRT, HT provided superior dose distribution to the PTVs while maintaining a comparable incidence of RP in patients undergoing thoracic radiotherapy.
