Impact of amalgam dental filling on radiotherapy of head and neck cancer: In vivo dosimetry and dose calculation using AAA and Acuros algorithms

Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.
Abstract Introduction Dental restorations using high‐density materials can cause inaccuracies in target and organ‐at‐risk (OAR) delineation and dose calculations during radiotherapy. These materials, such as amalgam, lead to dose scattering, resulting in enhanced mucositis in adjacent tissues.

Enhancement of dose distribution using tissue compensators in boron neutron capture therapy

Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.
Abstract In BNCT for head and neck tumors delivered with a horizontal beam, the presence of missing tissue near the beam path can cause reduction in neutron fluence rate in adjacent tissue regions due to the loss of scattered neutrons. These regions are referred to as neutron depleted areas.

Second Primary Cancer After Bladder Cancer: A Comprehensive Analysis of a National Cancer Registry

Cancer Medicine, Volume 14, Issue 23, December 2025.
ABSTRACT Background Bladder cancer (BC) is one of the most common cancers and many patients will experience long‐term survival. Non‐urothelial second primary cancers (SPC) relatively frequently occur in the population of BC survivors. Methods Czech National Cancer Registry was the principal data source for this study.

A Pedunculated Uvular Tumor Highlighting the Decline of Oropharyngeal Examination Skills

Clinical Case Reports, Volume 13, Issue 12, December 2025.
Endoscopic view of a pedunculated uvular tumor shifting toward the airway during insufflation. ABSTRACT Pedunculated uvular tumors, though rare, may cause airway symptoms when enlarged or elongated. This case highlights how diminished attention to basic oropharyngeal inspection in routine care can lead to missed diagnoses with potentially serious ...
