3 Clinical Trials for Various Conditions
Digital single-operator cholangioscopy (DSOC) findings achieve high diagnostic accuracy for neoplastic bile duct lesions. To date, there is not a universally accepted DSOC classification. Endoscopists' Intra and interobserver agreements vary widely. Cholangiocarcinoma (CCA) assessment through artificial intelligence (AI) tools is almost exclusively for intrahepatic CCA (iCCA). Therefore, more AI tools are necessary for assessing extrahepatic neoplastic bile duct lesions. In Ecuador, the investigators have recently proposed an AI model to classify bile duct lesions during real-time DSOC, which accurately detected malignancy patterns. This research pursues a clinical validation of our AI model for distinguishing between neoplastic and non-neoplastic bile duct lesions, compared with high DSOC experienced endoscopists.
The primary objective of this study is to assess the safety, tolerability and toxicity of preoperative HBOT in patients undergoing a pancreaticoduodenal resection for premalignant and malignant tumors of the common bile duct, periampullary and duodenum.
This study is for people with advanced cancer of the digestive tract and cancer that cannot be completely removed by surgery. Radiation therapy is commonly used in the treatment of these types of cancer in combination with a chemotherapy drug, called 5-fluorouracil (5-FU). In this study, doctors will administer the standard dose of radiation therapy in combination with an investigational chemotherapy drug, called irinotecan. Irinotecan can decrease the size of tumors and also appears to increase the effectiveness of radiation. The purpose of this study is to determine the highest dose of irinotecan that can be given safely in combination with radiation therapy, and to determine the side effects when these two treatments are given together. Irinotecan is approved by the Food and Drug Administration (FDA) for the treatment of colon cancer, but is not approved for cancers of the digestive tract. However, the FDA is allowing its use in this research study.
