CT scan to predict liver failure after surgery
This trial uses special CT scans to create a map of your liver's blood vessels before surgery. The goal is to predict if your liver might fail after part of it is removed, so doctors can better plan your care.
Minya, Minya GovernorateAges 18 years+ - NCT07726446RecruitingPhase 2
Freezing, immunotherapy, and chemo for bile duct tumors
This study tests a new treatment approach for bile duct or gallbladder cancer that has not been treated before. It combines a freezing procedure (cryoablation) with an immunotherapy drug (Relaforp Alpha) and chemotherapy to see if it can shrink tumors or slow disease progression.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT07724496Recruiting
H. pylori and stomach growth features study
This study looks at whether having H. pylori infection (a common stomach bacteria) and certain features of stomach growth can predict how early stomach cancer or pre-cancerous changes will behave and what your long-term outlook might be. You may be eligible if you are being treated with a camera-based removal procedure called endoscopic submucosal dissection (ESD).
Beijing, Beijing MunicipalityAges 18–80 - NCT07723937Recruiting
