摘要：

Background/Aim: The purpose of this study was to determine whether a semi-cylindrical beam spoiler (sCBS) developed herein effectively increases the skin dose in patients with early-stage glottic cancer. Patients and Methods: We measured the surface doses for 26 patients who used the sCBS during treatment of early-stage glottic cancer through a parallel-opposed lateral two-field 6 MV photon beam. Measurements were performed by attaching optically stimulated luminescent dosimeters to the left, right, anterior (in-field), inferior, and superior (out-field) sides of the patient. Results: The measured results were 81.8 +/- 2.1% (left), 81.0 +/- 1.7% (right), and 76.8 +/- 2.7% (anterior) in the in-field region compared to prescription doses, with 5.7 +/- 1.7% (superior) and 2.7 +/- 0.7% (inferior) in the out-field region. Conclusion: sCBS can deliver a suitably ideal surface dose for treatment of early-stage glottic cancer.
