Summary: The study investigated the dose reductions in individual cardiac segments from using the DIBH technique in left-sided breast cancer patients. It found that DIBH effectively reduced doses to the heart, left lung, left anterior descending coronary artery, and left ventricle, with the greatest absolute dose reductions seen in the distal LAD and apical LV segments. Lung expansion was significantly correlated with dose reductions in the LAD and LV segments.

Summary: This study compared the effects of mechanically-induced DIBH and SGRT-guided voluntary DIBH in breast radiotherapy. The results showed that mechanically-induced DIBH performed better in protecting and repositioning critical organs while achieving similar target irradiation accuracy as SGRT.

Summary: Deep Bidirectional Long Short-Term Memory (BLSTM) recurrent neural networks were used to predict eligibility for deep inspiration breath-hold (DIBH) radiotherapy treatment in patients with left breast cancer based on analysis of respiratory signals. The BLSTM-RNN accurately classified patients eligible for DIBH, achieving high accuracy, specificity, sensitivity, F1 score, and AUC in the test dataset. This provides promising results for the development of an accurate and robust decision system to assist the radiotherapy team in assigning patients to DIBH.

Summary: This retrospective study involving 2022 breast cancer patients treated with radiotherapy at West Pomeranian Oncology Center in Szczecin from January 1, 2014 through December 31, 2017, found that the use of deep inspiration breath hold (DIBH) significantly reduces the mean heart dose in patients with left breast cancer.

Summary: DIBH has shown significant advantages over FB in patients with left-sided breast cancer receiving radiotherapy, reducing heart, left anterior descending branch, and ipsilateral lung doses and volumes, while increasing ipsilateral lung volume.

Summary: This study compared the dosimetry and treatment efficiency of continuous semi-arc and tangent-arc plans in radiotherapy for breast cancer. The results showed that the tangent-arc plan had lower doses in the lung and spinal cord compared to the continuous semi-arc plan, and it also had a shorter treatment time, which greatly improved treatment efficiency.

Summary: ExacTrac Dynamic (ETD) provides a Deep Inspiration Breath Hold (DIBH) workflow for breast patients. The study aimed to determine appropriate imaging parameters, optimal Hounsfield Unit (HU) threshold, and workflow evaluation for DIBH breast treatments using a custom breast DIBH phantom. Parameters of 60 kV and 25mAs were determined appropriate for patient imaging and HU thresholds between -600 HU and -200 HU enabled adequate prepositioning. The study showed that ETD is suitable for clinical implementation during DIBH breast treatments.

Summary: This study evaluates the reproducibility and variability of breath-hold level (BHL) in left breast cancer patients using v-DIBH technique. The results show good reproducibility of BHL in different treatment fractions, but poor variability between planning and measured fractions.

Summary: This study compared the treatment delivery time and dosimetric differences between 8 partial arcs VMAT and 4 partial arcs VMAT for left-sided breast cancer patients using deep-inspiration breath hold technique. The results showed that 4 partial arcs VMAT significantly reduced treatment delivery time without compromising the treatment efficacy.

Summary: The use of deep inspiration breath hold and shallow breathing in the prone crawl position significantly reduces doses to the heart and lungs, leading to a decrease in mortality risk for different risk profiles of patients. Deep inspiration breath hold results in significant dose reductions for other organs-at-risk with photon radiotherapy, while minor differences are observed with proton radiotherapy.

Summary: The study involved ten left-sided breast cancer patients receiving DIBH radiotherapy, using SGRT to guide breath-hold and align chest wall position. Further integration of SGRT with image-guidance may improve treatment accuracy and workflow, although no significant accuracy improvements were shown in scenarios B and C compared to scenario A.

Summary: Adjuvant radiotherapy may harm the heart in left-sided breast cancer patients. The deep-inspiration-breath-hold technique can limit heart exposure to radiation. Anatomical predictors may aid insiders in treatment decisions and improving practitioner efficiency.

Summary: The study aims to evaluate the accuracy and agreement of a three-camera Catalyst Surface Guided radiation therapy system on a closed-gantry Halcyon for breast-only treatments under free-breathing and deep inspiration breath hold conditions. The agreement of SGRT positioning with the Halcyon couch and cone-beam computed tomography (CBCT) was evaluated and compared with the CBCT positioning. The results showed good agreement between SGRT and Halcyon couch, while some systematic differences were observed between SGRT and CBCT positioning.
