Locally Advanced Cervical Cancer Treated with Online Adaptive Radiotherapy: A Case Report

Online adaptive radiotherapy(OART)is considered to be a revolutionary technology after intensity-modulated radiotherapy. The first Chinese OART platform based on iterative cone beam computed tomography (iCBCT)has been applied in clinical treatment in Peking Union Medical College Hospital. This article reports the workflow and efficacy of first case with cervical cancer who received radical OART. After treatment, the patient achieved clinical complete remission with only a grade 1 radiation toxicity in the lower gastrointestinal tract. This article analyzes and discusses the clinical treatment process and follow-up data of this patient, aiming to provide clinical evidence for the subsequent large-scale application of artificial intelligence-driven iCBCT-guided OART technology.
