    Setup errors significantly impact dose distribution in hypofractionated radiotherapy for left-sided radical breast cancer.

  • 2

    CTVsc and CTVcw are most sensitive to setup errors in the superior and anterior directions, respectively.

  • 3

    Increased positioning errors from 3 mm to 9 mm lead to substantial decreases in D95% for both CTVsc and CTVcw.

  • 4

    The esophagus and thyroid are particularly sensitive to setup errors in the right direction, while the heart and LAD are sensitive in the posterior direction.

  • 5

    A setup error tolerance of 3 mm is recommended for CTVcw and OARs, while a tolerance of 5 mm may be acceptable for CTVsc.
