Conclusion:

Our comprehensive dosimetric analysis revealed that target volume coverage and adherence to dose constraints for heart and lung protection were generally satisfactory. Although a significant proportion of patients experienced acute skin-related effects, the majority achieved favorable aesthetic outcomes.

Notably, we identified significant differences in dosimetric parameters, particularly in the context of irradiation type (WBI vs. PBI) and the use of DIBH.

Remarkably, acute cutaneous effects did not exhibit significant disparities concerning dosimetric parameters. These findings underscore the imperative of meticulous radiation treatment planning and optimization to minimize risks and enhance therapeutic outcomes for breast cancer patients.

Ultrahypofractionation is a safe and feasible option even with locally advanced breast cancer and can be offered to older women.
