Xiujuan Zhao & Dongling Zou et al. · 2025-07-09

To investigate the ramifications of dose alterations and clinical outcomes linked to imperfect uterine tandem implantation within high dose rate brachytherapy (HDR-brachytherapy) for cervical cancer. A retrospective analysis was conducted on imperfect intrauterine insertion images from November 2020 to July 2021. The physicist reconfigured two-dimensions (2D) and three-dimensions (3D) plans based on prescription (6 Gy) for both the imperfection (IM) and perfect (PER) implantation. A paired t-test was employed to assess (reference volume of clinical target volume) CTV
