NCT07588854
The goal of this clinical study is to learn whether the Olympus EU-ME3 endoscopic ultrasound shear wave quantification (EUS-SWQ) function can accurately diagnose and grade liver fibrosis in patients with chronic liver disease. It will also learn about the safety and measurement success rate of EUS-SWQ. The main questions it aims to answer are: How closely do EUS-SWQ measurements match liver fibrosis stages determined by liver biopsy (the reference standard)? Does EUS-SWQ correlate better with liver biopsy results than FibroScan? How safe is EUS-SWQ and how often can successful measurements be obtained? Researchers will compare EUS-SWQ results with liver biopsy pathology (METAVIR F0-F4) and with FibroScan results to evaluate its diagnostic value. Participants will: Be adults with chronic liver disease who are scheduled to undergo a clinically indicated liver biopsy Undergo an EUS-SWQ examination as part of the study Have their liver stiffness measured by both EUS-SWQ and FibroScan for comparison Be monitored for any discomfort or adverse events related to the procedures A total of 65 participants will take part in this prospective, single-center, post-market clinical study.
NCT06868394
Cancer survivors are at a high risk to develop second primary malignancy (SPM) which constitutes a serious threat for them. Radiotherapy is the cornerstone for the management of many cancers as a locoregional treatment modality. Due to the low liver tolerance, cirrhotic patients are at a high risk of developing radiation-induced liver toxicities despite the modern safe radiation delivery techniques. Radiation damages cells through direct energy deposition and reactive free radical generation. Recent studies demonstrated a potential risk of SPMs following radiotherapy with further investigations for strategies to decrease radiation-induced SPMs. However, it is insufficiently addressed if developing liver SPMs is a serious adverse event following radiotherapy for cirrhotic patients. The aim of this study was to quantitatively assess the risk of gastrointestinal (GI) and liver SPMs following radiotherapy in patients with chronic liver disease.
