What Researchers Did
Researchers described the protocol for the HOPON trial, a phase III, multi-centre randomized controlled trial designed to assess hyperbaric oxygen for preventing osteoradionecrosis during surgery on the irradiated mandible.
What They Found
This paper outlines the design for a trial where patients requiring high-risk dental procedures in the mandible after at least 50-Gy radiotherapy will be randomized 1:1 to either a hyperbaric oxygen arm or a control arm. The primary endpoint will be the presence of osteoradionecrosis at 6 months following surgery, with secondary endpoints including acute symptoms, pain, and quality of life.
What This Means for Canadian Patients
If the HOPON trial demonstrates efficacy, it could provide robust evidence for using hyperbaric oxygen to prevent osteoradionecrosis in Canadian patients undergoing dental procedures after head and neck radiotherapy. This evidence would help standardize care and potentially improve outcomes for those at high risk, as current clinical practice varies greatly.
Canadian Relevance
This study protocol does not have a direct Canadian connection as it describes a multi-centre trial conducted outside of Canada.
Study Limitations
A limitation of this paper is that it describes a study protocol and therefore does not present clinical results or definitive conclusions regarding treatment efficacy.
