Clinical investigation of use of Episil® oral solution in oral mucositis during radiotherapy for head and neck cancer.

Objective: Episil® is a bio adhesive barrier-forming oral liquid gel that has been used in recent years to relieve pain of oral mucositis (OM) with radiotherapy (RT) or chemoradiotherapy (CRT) in head and neck cancer (HNC) patients. We conducted a retrospective analysis of the clinical effects of Episil® on OM in these patients.

Study Design: Between June 2018 and May 2020, 65 patients with HNC were treated with RT or CRT at our hospital.
