Brief Summary

Recently developed hybrid machines (MRidian®-CE approval since 2016), consisting of a linear accelerator and an integrated low-field MRI, could allow better visualization of tumor and organs at risk during patient positioning and daily treatment finally repetitive adaptation of target volumes according to changes in patient weight and tumor anatomy during the radiotherapy course. These procedures would facilitate a high-precision treatment and help reduce dose exposure of critical structures.

EXPERIMENTAL

Radiation: Radiotherapy

Interventions

Radiotherapy RADIATION

Radiotherapy: All patients were treated with Unity MRI Linac intensity modulated radiation therapy, daily imaging of MRI-IGRT and online target delineation, redesign, and total radiation dose: GTV 70Gy/33f, GTVLN 70Gy/33f, CTV 60Gy/33f, CTVLN 54Gy/33f, 5 days per week. Dose limit: The average dose to the upper, middle, and lower pharyngeal constrictor muscles is ≤ 40-50Gy, with oropharyngeal cancer requiring an average dose to the upper, middle, and lower pharyngeal constrictor muscles to be ≤ 50Gy and ≤ 20Gy; Lower pharyngeal cancer requires an average dose of ≤ 40Gy for the upper and middle pharyngeal constrictor muscles, and ≤ 50Gy for the lower pharyngeal constrictor muscles. chemotherapy: cisplatin 75mg/m2, 21 days per cycle, a total of 3 cycles.
