The dosimetric and clinical comparison between helical tomotherapy and fixed-field intensity-modulated radiotherapy in radical irradiation for cervical cancer
MATERIALS AND METHODS
Patient's characteristicsFrom November 2016 to December 2018, 77 cervical cancer patients (Karnofsky performance status (KPS) ≥ 70) undergoing radical radiotherapy with HT or fixed-field intensity-modulated radiotherapy (f-IMRT) in Chongqing University Cancer Hospital were selected. All patients completed the following examinations: careful gynecological examination, tumor marker tests, chest X-ray or computed tomography (CT) scans, magnetic resonance imaging (MRI) scans or CT scans of the pelvic cavity. The staging of disease was according to the International Federation of Gynecology and Obstetrics (FIGO) criteria. This study was approved by the ethics committee of Chongqing University Cancer Hospital, and the informed consent was acquired from each enrolled patient.
