Is intensity-modulated radiotherapy better than conventional radiation treatment and three-dimensional conformal radiotherapy for mediastinal masses in patients with Hodgkin’s disease, and is there a role for beam orientation optimization and dose constraints assigned to virtual volumes?
30 Οκτ 2019 · Mediastinal radiotherapy with doses of around 40 Gy with the 2D-RT technique increases the risk of cardiovascular death roughly six fold. The risk is the highest ten years post-treatment and increases with heart-D mean, increasing inhomogeneity of the absorbed heart dose and depends on age at diagnosis.
18 Οκτ 2018 · Minimizing radiation to OARs in adults patients with Hodgkin and non-Hodgkin lymphomas involving the mediastinum is the deciding factor for the choice of treatment modality. Proton therapy may help to reduce the radiation dose to the OARs and reduce toxicities, especially the risks for cardiac morbidity and second cancers.
1 Ιουν 2016 · Radiation therapy is an important modality in the treatment of patients with malignant chest neoplasms. Radiologists need to be familiar with postradiotherapy imaging findings within the mediastinum and its surrounding organs, as well as be familiar with modern technologies of radiation delivery.
management often requires radiotherapy (RT) de-livered neoadjuvantly or adjuvantly to surgical in-tervention. Recent innovations in radiotherapy allow for improved tumor targeting and more pre-cise radiation dose delivery. This article describes diseases of the mediastinum commonly treated with RT, and how innovations in RT planning and
8 Απρ 2022 · The strongest risk factor for developing radiation-induced VHD is the total radiation dose delivered to the mediastinum, more specifically the total dose delivered to the heart valves.
1 Μαρ 2021 · Median SBRT dose was 35 Gy (range, 30-50 Gy) with a median biologically effective dose of 59.5 Gy (range, 48-100 Gy). All treatments were in 5 fractions. Seven grade ≥3 toxicities were experienced by 6 patients (11.5%) and were mostly transient (5/7; 71%). There was a single (1.9%) grade 5 toxicity (radiation pneumonitis).
