TORPEdO: IMPT vs IMRT chemoRT in locally advanced OPSCC, 12-mo tube dependence/severe weight loss 18% vs 7% (p=0.079), UW-QoL 78.3 vs 77.1 (p=0.56), no functional gain.
The one head-neck readout: TORPEdO, a phase 3 RCT of IMPT vs IMRT (N=205, 70 Gy/33 fx + cisplatin). Protons lowered OAR doses but gave no 12-mo functional gain. Tube dependence/severe weight loss was 18% vs 7% (p=0.079) and UW-QoL 78.3 vs 77.1 (p=0.56). Weigh this against missed fractions in 49% of IMPT pts and a two-centre pathway confound.
