Virtual RealiTy and mUsic in the Oncology SEtting - Phase 1

VRtuose (phase 1) is a non-randomized, single-centre, prospective, feasibility study conducted in the day patient chemotherapy unit of the Centre Léon Bérard in Lyon. This study will include women diagnosed with breast cancer who are receiving or are planned to receive any chemotherapy regimen. As this is a feasibility study, there will be no control group and all participants will be offered the intervention.

The intervention will be implemented from the first chemotherapy session onwards until it has been offered at four distinct chemotherapy sessions or until the end of patients' chemotherapy course if it is ended earlier. The intervention will be offered in addition to the standard of care at the study hospital.

All women with breast cancer who are about to start or who have started chemotherapy will be considered for inclusion in the study. All participants will be offered the distraction strategy for four consecutive chemotherapy sessions spanning over their chemotherapy course (i.e., from the first session onwards) whenever the strategy is available for use.

The intervention will be characterised by a strategy combining immersive virtual reality and music delivered during chemotherapy sessions to breast cancer patients by trained oncology nurses. Different immersive environments and of music will be available to the choice of the patient. From the first chemotherapy session onwards, patients will be offered by oncology nurses to use the distraction strategy during their chemotherapy session. Patients who are willing to use the strategy will have the possibility to choose the content of the strategy and to use it for the duration of their choice. Patients will be followed up from recruitment until they have been offered four times to use the strategy (or until the end of their chemotherapy course if it ends earlier).

This study will assess the feasibility to implement such a strategy into a day-hospital chemotherapy unit at a major oncology centre, and will therefore collect information on feasibility, acceptability and tolerability outcomes of using the strategy in this context. The efficacy of the strategy to improve patients' quality of life will not be evaluated in this study.
