Objective: Reflux oesophagitis (RO) is one of the most common diseases encountered by gastroenterologists and primary care physicians. However, few epidemiological studies have investigated the association of medication use and RO. This study aimed to investigate the prevalence of RO and its risk factors, particularly with respect to medication use.

The neutron beam in boron neutron capture therapy (BNCT) exhibits poor directionality and significantly decreasing neutron flux with increasing distance. Therefore, the treatment site must be close to the irradiation aperture. Some patients with head and neck cancer may benefit from a sitting-position setup.

Background: Accelerator-based boron neutron capture therapy (AB-BNCT) systems are becoming commercially available and are expected to be widely used in hospitals. To ensure the safety of BNCT, establishing a quality assurance (QA) program and properly managing the stability of the system are necessary. In particular, a high level of beam output stability is required to avoid accidents because beam output is a major factor in patient dose.

Article Synopsis
  • The study investigated the operational times of image-guided brachytherapy for cervical cancer patients, focusing on different types of brachytherapy sessions conducted between 2020 and 2024.
  • A total of 126 sessions were analyzed, revealing that sessions with both intracavitary and interstitial brachytherapy (IC/ISBT) took significantly longer than those with only intracavitary brachytherapy (ICBT), especially when three or more interstitial needles were used.
  • The findings indicated that using one interstitial needle showed no significant difference in operation time compared to ICBT-only sessions, and that total operational time was similar across different imaging techniques (CBCT, CT, CT + MRI).

Purpose: In Japan, immunohistochemistry for mismatch repair (MMR) proteins targeted at stage II and III colorectal cancers (CRCs) has been covered by national insurance since October, 2022. This study aimed to clarify the long-term outcomes of patients with stage II and III CRCs receiving postoperative adjuvant chemotherapy based on their MMR status.

Methods: The outcomes of 640 patients who underwent radical surgery for stage II and III CRCs were analyzed retrospectively.
