One‐year follow‐up after fractionated ultra‐high‐dose‐rate FLASH radiotherapy in patient with extramammary Paget disease of the scrotum

Precision Radiation Oncology, EarlyView.
An elderly male patient with extramammary Paget disease of the scrotum and multiple metastases was treated with fractionated FLASH‐RT (40 Gy in 5 fractions) in the scrotal lesion. Abstract Objective Ultrahigh‐dose‐rate radiotherapy (FLASH‐RT) has been shown to reduce radiation‐induced normal tissue injury in preclinical studies.

Risk Factors and Predictive Model for Otitis Media With Effusion After Radiotherapy in Nasopharyngeal Carcinoma: A Retrospective Study

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To investigate the impact of different radiation fields on the risk of otitis media with effusion (OME) in nasopharyngeal carcinoma (NPC) patients and to develop a nomogram to identify high‐risk patients after radiotherapy. Methods Clinical data were collected from 170 NPC patients who underwent radiotherapy at Peking Union Medical ...

Dose‐Dependent Effects of Simulated Clinical Radiotherapy on the Structure and Properties of Root Dentine

Australian Endodontic Journal, EarlyView.
ABSTRACT Head and neck radiotherapy (HNRT) can expose teeth to moderate radiation doses, yet the effects on root dentine under clinically relevant conditions remain unclear. This in vitro study compared dentine subjected to 0, 30, or 50 Gy IMRT. Palatal roots from 35 maxillary molars were allocated to non‐irradiated, 30 Gy (oropharyngeal simulation ...
