Treatment With the Shaker Head‐Lift Exercise in Head and Neck Cancer Patients With Radiation‐Induced Dysphagia: 12‐Month Results on Swallowing Function From a Randomized, Controlled Trial

Head &Neck, EarlyView.
ABSTRACT Background Dysphagia is a common side‐effect after radiotherapy in head and neck cancer patients. This randomized study aimed to evaluate the effect of the shaker head‐lift exercise (HLE) after 12 months with flexible endoscopic evaluation of swallowing (FEES). Methods Patients were randomly assigned to the intervention (n = 30) or the control

Twelve‐Month Outcomes of a Preventive Dysphagia Intervention in Patients With Head and Neck Cancer—A Randomized Study

Head &Neck, EarlyView.
ABSTRACT Background Radiation‐associated dysphagia is common after radiotherapy for head and neck cancer and may occur early or years later. The effect of preventive exercises might be undermined by poor adherence. Aim To evaluate the effect of a simple preventive exercise protocol on swallowing function up to 12 months after radiotherapy.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...
