Purpose: We developed software that can analyze central lung distance (CLD) and central skin distance (CSD) in deep inspiration breath hold (DIBH) irradiation and verified the reproducibility of the DIBH irradiation method in our hospital.
Methods: CLD and CSD were analyzed using In-house software using cine images acquired during treatment; intra- or inter-fractional motion was calculated from the obtained data and compared with other reports using systematic error (ΔΣ) and random error (Δσ).
Results: The ΔΣ and Δσ were 1.15 mm and 1.53 mm, respectively, which were the same as those reported in other reports.
Conclusion: The reproducibility of the irradiation method for left breast DIBH irradiation at our hospital is considered good. Due to its characteristics, regular and quantitative evaluation is required, and verification and evaluation are required at each facility.

To compare dosimetric outcomes between Free Breath (FB) and Deep Inspiration Breath Hold (DIBH) across different radiotherapy modalities, establish patient selection criteria for DIBH, and optimizing the setup margin (SM) in left breast cancer treatment. 26 patients with left breast cancer were studied at CRO, Aviano in Italy. FB and DIBH simulations were done using CT with a real-time position management system.

Objective: To analyse the dosimetric benefit achieved with Deep inspiratory breath hold (DIBH) for left sided breast irradiation and to identify the factors impacting it.
Methods: Between 1st January'2023 to 31st December' 2023, 100 consecutive patients with left sided breast cancer receiving adjuvant radiotherapy and fulfilling the inclusion/exclusion criteria were enrolled in a prospective study conducted at Rajiv Gandhi Cancer Institute and Research Centre, New Delhi. Two radiotherapy plans (DIBH/Free breathing (FB)) were generated and evaluated for each patient.

Background: To assess the dose-sparing capabilities of a yaw-limited volumetric modulated arc therapy (YL_VMAT) beam setup for adjacent organs at risk (OAR) in comparison with 3D-conventional radiation therapy (3D-CRT), intensity-modulated radiation therapy (IMRT) and conventional VMAT for radiation therapy in left-sided breast cancer patients.
Methods: In total, 80 treatment plans for 20 patients, of which 10 patients underwent CT-scans in deep inspiration breath-hold (DIBH) and 10 patients in free-breathing (FB) technique. Besides generally tangential-weighted static and IMRT beams, VMAT treatment plans with approximately 270° arc length have been compared and analyzed to a multi-field, yaw-adapted, unconventional partial VMAT technique retrospectively.

Background: Radiotherapy for left-sided breast cancer is associated with additional cardiac risks. Deep inspiration breath hold (DIBH) has emerged as the primary cardiac sparing technique, demonstrating significant reduction in mean heart dose (MHD) and left anterior descending coronary artery (LAD) dose. However, the issue of whether dosimetric advantages can be effectively translated into clinically measurable benefits for patients remains to be further elucidated.
