Heart and lung sparing with isocentric lateral decubitus positioning compared with dorsal decubitus positioning during adjuvant localized breast cancer radiotherapy.

Objectives: The cardiac and pulmonary dosimetric benefit of alternative positioning in isocentric lateral decubitus compared with dorsal decubitus during adjuvant breast irradiation has yet to be proven, in spite of the relative long-standing use of isocentric lateral decubitus.

Methods: Eight consecutive patients with an indication for adjuvant breast irradiation without boost or lymph node irradiation were scanned in both isocentric lateral and dorsal decubitus positions. For each patient, a plan delivering 40.

Long-term cardiac mortality in patients treated with radiation for gastric mucosa-associated lymphoid tissue lymphoma.

Purpose: Limited-stage gastric mucosa-associated lymphoid tissue (MALT) lymphoma can be treated with radiation alone. Due to the immediate proximity of the stomach to the heart, there is a theoretical risk of radiation-induced cardiac toxicity, the incidence of which has never been precisely studied. The aim of this study was to assess cardiac-specific mortality in patients treated for gastric MALT lymphoma with radiation.

Long-Term Results of Intensity Modulated Radiotherapy (IMRT) with Helical Tomotherapy in Non-Metastatic Breast Cancer Patients: Final Analysis.

Intensity modulated radiotherapy with helical tomotherapy (IMRT-HT) is used in the breast cancer (BC) treatment for years now to obtain homogeneous dose distribution in the treated volumes and reduce the doses to organs at risk. The purpose of this study was to evaluate our experience in terms of local control, overall survival, progression free survival and adverse events in BC patients treated with IMRT-HT with long term follow-up. This study is a retrospective data analysis of patients irradiated with IMRT-HT.

Automated contouring for breast cancer radiotherapy in the isocentric lateral decubitus position: a neural network-based solution for enhanced precision and efficiency.

Background: Adjuvant radiotherapy is essential for reducing local recurrence and improving survival in breast cancer patients, but it carries a risk of ischemic cardiac toxicity, which increases with heart exposure. The isocentric lateral decubitus position, where the breast rests flat on a support, reduces heart exposure and leads to delivery of a more uniform dose. This position is particularly beneficial for patients with unique anatomies, such as those with pectus excavatum or larger breast sizes.
