Analysis of dosimetric improvements using hydrogel spacer in high-dose-rate brachytherapy for prostate cancer
HS effectively reduced rectal doses and improved V<sub>100%</sub> and D<sub>90%</sub> in the dorsal apex and dorsal mid regions of the prostate. These regions are anatomically closer to the rectum and are often subject to dose constraints as well as critical areas for sufficient dose delivery because of the frequent localization of prostate cancer lesions. Therefore, HS is particularly beneficial for patients with dominant lesions in these regions.
