Article Synopsis
- This study explored how the spinal cord and canal moved during real-time adaptive radiotherapy for kidney cancer, focusing on MR-guided treatments from February 2022 to February 2024.
- The research involved 22 patients receiving precise doses of radiation, with MRI scans taken at three different points during treatment to assess movement.
- Findings showed minimal movement of the spinal cord, but emphasized that specific margins are needed in treatment planning to ensure patient safety amidst these movements.
Background: There have been several reports showing that heart-related deaths are common in long-term survivors of esophageal cancer after radiation therapy; however, radiotherapy technology is evolving year by year. This study was carried out using the SEER database to determine whether the frequency of mortality from heart disease after radiotherapy has improved over time in patients with esophageal cancer.
Methods: SEER*Stat statistical software version 8.
Article Synopsis
- - The study assessed the CARE-Radiology checklist's reliability and usability for evaluating radiological case reports, aiming to encourage its wider use and improvement.
- - Ten case reports from 2020 were reviewed by 26 experts from 10 different countries, measuring the checklist's effectiveness using statistical methods like Fleiss' Kappa and Cronbach's alpha.
- - Results showed moderate reliability, with a mean compliance rate of 61.8% for checklist items, and while most evaluators found it easy to use, certain areas need feedback for future enhancements.
Introduction: Patients with esophageal cancer who are in a poor general condition receive radiotherapy alone, but outcomes are often unsatisfactory. The aim of this study was to clarify recent outcomes of radiotherapy alone for esophageal cancer.
Methods: Patients who underwent 50 Gy or more of radiotherapy without chemotherapy were retrospectively reviewed.
Background: There has been no study in which the correlation between clinical results and dosimetry based on a 3D treatment planning system in patients with Au grains for head and neck cancer was evaluated.
Methods: Thirty-two patients who were treated with Au grains for head and neck cancer were reviewed. Twenty-five patients were treated with brachytherapy alone and seven patients were treated with a combination of brachytherapy and neoadjuvant external beam radiation therapy.
