Background: Apart from superior soft tissue contrast, MR-guided stereotactic body radiation therapy (SBRT) offers the chance for daily online plan adaptation. This study reports on the comparison of dose parameters before and after online plan adaptation in MR-guided SBRT of localized prostate cancer.
Materials And Methods: 32 consecutive patients treated with ultrahypofractionated SBRT for localized prostate cancer within the prospective SMILE trial underwent a planning process for MR-guided radiotherapy with 37.
Article Synopsis
- The study investigates risk factors and dosimetry characteristics linked to capsular contracture in women who had breast cancer and underwent reconstructive surgery with post-mastectomy radiation therapy (PMRT).
- A retrospective analysis of 118 women revealed that 22.9% experienced significant capsular contracture (Baker III-IV) after a median follow-up of 22 months, with an overall incidence of 47.5% for all levels of capsular contracture.
- Key findings indicate that postoperative complications and regional nodal involvement increased the risk of capsular contracture, while dosimetric factors and implant position did not show any significant association.
The field of radiotherapy is highly marked by the lack of datasets even with the availability of public datasets. Our study uses a very limited dataset to provide insights on essential parameters needed to automatically and accurately segment individual bones on planning CT images of head and neck cancer patients.The study was conducted using 30 planning CT images of real patients acquired from 5 different cohorts.

Methods: We retrospectively reviewed 10 consecutive patients undergoing PRT for advanced JNA in a definitive or postoperative setting with a relative biological effectiveness weighted dose of 45 Gy in 25 fractions between 2012 and 2022 at the Heidelberg Ion Beam Therapy Center. Furthermore, dosimetric comparisons and risk estimations for short- and long-term radiation-induced complications between PRT plans and helical XRT plans were conducted.
(1) Background: Magnetic-resonance (MR)-guided stereotactic body radiotherapy (SBRT) allows for ablative, non-invasive treatment of liver metastases. However, long-term clinical outcome data are missing. (2) Methods: Patients received MR-guided SBRT with a MRIdian Linac between January 2019 and October 2021 and were part of an ongoing prospective observational registry.
