In this study, we evaluate nuclear reaction cross sections using Antisymmetrized Molecular Dynamics, a quantum-theoretical reaction model. These cross sections are introduced into transport calculations to improve dose-distribution evaluation in heavy-ion cancer therapy. Conventional transport codes mainly rely on semiclassical approaches for heavy-ion induced reactions. Such methods cannot fully reproduce fermionic properties, which limits the reproducibility of secondary-fragment production. In this work, we implement quantum-theoretical cross sections in PHITS and compare them with conventional settings. We investigate model and mean-field dependencies in the transport results. The analysis shows that mean-field effects appear even at the transport level and that improved cross sections can enhance the stability and reliability of dose evaluation.
