A translation app on a media device to assist patients undergoing breast RT in DIBH was tested and trialled in order to review the use of non-intrusive live translation so DIBH can be offered to all patients.

Material/Methods: At referral, the clinician documented if a patient was a non-English speaker and would need DIBH translations. The pre-treatment team added required phrases to a media device in the patient’s spoken language. The phrases were verified by staff members who are fluent in the same language and they were recorded into the CT scanner. Translators were booked for the first pre-treatment and treatment appointments for information giving. At pre-treatment, patient suitability was assessed using specific verbal instructions testing the depth and consistency of breath and the patient’s ability to relax into the same position on exhale. They were coached by radiographers to achieve the required breath hold. If the patient was able to achieve DIBH using the translations, their treatment was planned in DIBH and the media device was used to translate instructions for treatment delivery. The pre-treatment and treatment teams worked collaboratively to ensure the instructions were available in both the CT scanner and linear accelerators. Continuous feedback between the teams was obtained to enable improvements to the technique for future patients. Results: Since April 2023, 22 patients have been successfully scanned and treated for breast and/or IMC cancer using this technique in 11 different languages. The translation app was utilized at pre-treatment for a further 8 patients but they were unable to achieve DIBH. Not all languages were available on the translation app. Conclusion: The department is now using this technique for non-English speaking breast and lymphoma DIBH patients as standard.

Digital Poster Comparison of Two Immobilization Systems in Thoracic Stereotactic Body Radiotherapy: Impact on Reproducibility and Immobilization Efficiency Cassandra VALENTA, Benjamin COLSON, Magalie MOLLET, Leila ETTALHAOUI, Felix FELICI, Camille INVERNIZZI, Sofiane GUENDOUZEN, Mauro RODRIGUES CARREIRA, Alexandre ROQUE, Philippe GUILBERT, Arnaurd BEDDOK radiation oncology, godinot institute, REIMS, France Purpose/Objective: The choice of immobilization system is critical in thoracic stereotactic body radiotherapy (SBRT), as it influences both patient comfort and workflow efficiency. The thermoformed mask requires additional setup time and greater expertise from radiation therapists, potentially increasing workflow complexity. This study aimed to compare the effectiveness and reproducibility of two immobilization systems used in thoracic SBRT to evaluate the utility of customized immobilization devices.
