  Objective: To retrospectively evaluate the effectiveness of cone-beam computed tomography (CBCT)-based repositioning during prostate radiotherapy and to assess its impact on treatment accuracy and safety margins. Methods: This retrospective study included a cohort of patients with prostate cancer treated with external beam radiotherapy at Casablanca General Hospital. For each treatment session, a CBCT scan was acquired to quantify interfractional setup deviations along the left-right (LR), anterior-posterior (AP), and superior-inferior (SI) axes. Statistical analyses were performed to determine the mean displacements and the probability of exceeding conventional safety margins. Results: Overall, several hundred CBCT scans were analyzed. The mean displacements were 0.31 cm along the LR axis, 0.21 cm along the SI axis, and less than 0.5 cm along the AP axis. The probabil.. Read More»
