Key Points

Upright positioning enhances organ sparing during carbon-ion radiotherapy and improves treatment effectiveness.
The preferred angle of 15° maximizes robustness while minimizing dose to organs at risk.
Analysis involves comparisons between upright and angled supine setups, assessing effectiveness and safety profiles.
Findings may guide clinical practice for optimizing radiotherapy techniques in head and neck cancers.

Implication

Upright positioning improves robustness and organ sparing in carbon-ion radiotherapy, indicating better treatment options.

Abstract

The anterior beams at 15°in the upright setup (U15) showed the best balance of robustness and OAR sparing, making it the preferred option. The 15°-angled supine setup (S15) is a practical alternative. S0 and U45 are not recommended due to inferior robustness and higher brainstem dose, respectively.
