Purpose/Objective:

Adjuvant radiation therapy (RT) is the standard of care for patients with breast cancer, post breast-conserving surgery (BCS) and mastectomy 1 . However, there are associated radiation-induced toxicities, especially cardiac-related, that are concerning. The use of breath-hold (BH) techniques has the potential to reduce the dose to organs-at-risk (OARs). The most common approach is Deep Inspiration Breath-Hold (DIBH), which has been highly advantageous at reducing the cardiac dose associated with irradiating patients with left breast cancer. Patients who have substantial hearing impairments have difficulties hearing verbal prompts during DIBH. Thus, they are usually not considered candidates for DIBH. This study aims to establish a consensus on the ideal characteristics of a supportive device to enable patients with hearing impairments to undergo RT using DIBH.

Material/Methods:

A qualitative approach was utilised. Semi-structured interviews were conducted with major stakeholders from a range of backgrounds including radiation oncologists (ROs), (n=2), radiation therapists (RTTs) (n=2), medical physicists (MPs) (n=2), radiation therapy services managers (RTSMs) (n=2), an industry vendor (n=1), and deaf service users (SUs) (n=2). A sign language interpreter was present for the SUs interview. The interviews were semi-structured and included a set of predetermined questions. Data were analysed using thematic analysis applying Clarke and Braun’s six step data analysis process 2 .
