Quantification of head and neck cancer patients' anatomical changes during radiotherapy: Toward the prediction of replanning need

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Head and neck cancer (HNC) patients undergoing radiotherapy (RT) may experience anatomical changes during treatment, which can compromise the validity of the initial treatment plan, necessitating replanning. However, ad hoc replanning disrupts clinical workflows and increases workload.

Expert Perspective: Diagnosis and Treatment of Castleman Disease

open access: yesArthritis &Rheumatology, Volume 78, Issue 1, Page 12-25, January 2026.
Castleman disease (CD) is a major diagnostic challenge for rheumatologists.
