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 ...

Investigation Into the Utility of 3D Speckle‐Tracking Echocardiography in Detecting Coronary Artery Microcirculation Dysfunction in Ischemia With Non‐Obstructive Coronary Artery Disease

Journal of Clinical Ultrasound, EarlyView.
By detecting the subtle regional contractile dysfunction, 3D‐STE can efficiently distinguish CMCD and present a novel strategy for diagnosing INOCA. ABSTRACT Aim To assess the utility of three‐dimensional speckle‐tracking echocardiography (3D‐STE) in detecting coronary artery microcirculation dysfunction (CMCD) with non‐obstructive coronary artery ...

Neoadjuvant Chemotherapy With Gemcitabine/Cisplatin/S‐1 for Resectable Biliary Tract Cancer With FDG‐PET‐Positive Lymph Node Metastasis (KHBO1201): A Multicenter Phase II Trial

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Purpose To evaluate the safety and efficacy of neoadjuvant gemcitabine, cisplatin, and S‐1 (GCS) chemotherapy for resectable biliary tract cancer (BTC) and FDG‐PET‐positive lymph nodes in a multicenter phase II study (KHBO1201). Methods Patients with resectable BTC (intrahepatic/extrahepatic bile duct, gallbladder, or ampullary cancers) and ...
