VIBE - Virtual Image Guided Brachytherapy Emulation for Locally Advanced Cervical Cancer (LACC)

Overview

This study will evaluate the role of SBRT with the aim to reproduce high dose rate brachytherapy (HDR BT) dose distribution by means of external beam radiotherapy in the radical treatment in patients with LACC. The study will employ devices to accurately reproduce pelvic anatomy and mitigate target motion and will make use of real-time online tracking.

This is a phase I/II feasibility study of hypofractionated, image-guided Volumetric Modulated Arc Therapy (VMAT) Stereotactic Body Radiotherapy (SBRT) to LACC with the aim to reproduce HDR BT dose distribution by means of external beam radiotherapy in the radical treatment in patients with LACC. The study will employ devices to accurately reproduce pelvic anatomy and mitigate target motion and will make use of real-time online tracking. Eligible patients who consent to participate in the current study will receive 4 image-guided SBRT sessions to a prescription of 7 Gray per fraction to the LACC (HR-CTV) following whole pelvis external beam radiotherapy. SBRT will start within one week after whole pelvis external beam radiotherapy. The study will enroll a total of 30 patients. After treatment, patients will be followed-up at 1 month, at 3 months (+/- 1 week), at 6 months (+/- 4 weeks), and then every 6 months (+/- 6 weeks) until the end of the 3rd year, then annually until the 5th year. The equivalence of outcome and toxicity will be measured by comparing the data obtained in the study to literature data regarding the standard modality of brachytherapy. Patients' oncological outcomes, toxicity and quality of life data will be reported.
