: Radiotherapy represents the only treatment option for patients with inoperable endometrial cancer (EC). The aim of our study was to evaluate the efficacy and safety of brachytherapy (BT) in this selected patient population. : Between 1990 and 2019, 18 patients with inoperable EC in stage FIGO I-IV were treated with intracavitary brachytherapy using the "Heyman Packing technique".

Our study aimed to assess the impact of table movements and table sag on the breathing curves recorded in four-dimensional (4D) CT and deep-inspiration breath-hold (DIBH) CT.
Methods: For breathing curve measurements, static and dynamic phantom scenarios were used.
Article Synopsis
- The study investigates the effectiveness of modern cone-beam computed tomography (CBCT) imaging in brachytherapy compared to traditional computed tomography (CT) scans.
- Researchers conducted a phantom study to analyze CT numbers and electron densities for different materials and compared dose calculations for patients with cervical and breast cancer.
- Results showed no significant differences in dose parameters between planning CTs and control CBCTs, but highlighted the need for further investigation into dosimetric differences and emphasized the importance of treatment quality assurance due to larger interfractional variations.
Background/objectives: Advanced rectal cancer is one of the most common cancers worldwide and has a significant impact on public health. Because favorable and long-term survival has been achieved with multimodal therapy, patient quality of life is very important. The intention of this study was to assess patients' quality of life using various functioning and symptom scores from the years 2010 to 2022 and to examine changes over time.
