The Characteristics of Oral Microbiota in Chronic Pancreatitis and Autoimmune Pancreatitis
There are more than 700 different bacteria colonized in human oral cavity, which are collectively referred to as oral microbiota. Emerging evidence suggests that oral microbiota plays a series of important roles in human health, such as immune response, carcinogen metabolism and nutrient digestion. The changes of oral microbiota composition …
Real-World Study on Nano-Crystalline Megestrol Acetate for Cachexia in TKI-Treated Advanced Digestive Tumors
This study is a prospective, observational clinical study aimed at evaluating the efficacy of Megestrol Acetate for cachexia in patients with advanced digestive system tumors receiving TKI-based therapy.
Characteristics of Intestinal Microbiome Following Pancreatic Surgery
The goal of this observational study is to learn about intestinal microbiome structure and function in individuals who have undergone a pancreatoduodenectomy and compare to healthy matched controls. The primary objectives of the study are: To explore and describe any differences in the gut microbiota especially Shannon diversity index To …
Profiling the Intratumoral Microbiome of Pancreatic Ductal Adenocarcinoma Based on EUS-FNB Tissue Samples and Exploring Its Impact on Tumor Diagnosis and Prognosis.
The goal of this observational study is to use endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) to investigate the intratumoral microbiome profile in patients with pancreatic ductal adenocarcinoma (PDAC) and to evaluate its potential impact on tumor diagnosis and prognosis. PDAC is the most common and lethal type of pancreatic cancer, accounting …
Sarcopenia and Neuromuscular Block in Gastrointestinal Cancer Surgery
This prospective observational study aims to evaluate the effects of sarcopenia on intraoperative neuromuscular block (NMB) in patients undergoing gastrointestinal cancer surgery. Adult patients scheduled for elective gastrointestinal cancer surgery will be grouped as sarcopenic or non-sarcopenic based on preoperative abdominal CT scans. Neuromuscular block parameters, including onset time, depth, …
Radiographic Response to Chemotherapy in Unresected Localized Pancreatic Cancer
The goal of this observational study is to explore whether contrast-enhanced ultrasound (CEUS) can early predict and evaluate the treatment response of first-line chemotherapy in locally advanced and borderline resectable pancreatic cancers. The main questions it aims to answer are: Question 1: What quantitative parameters of CEUS performed before first-line …
PREOPANC-4 Implementation Program for Locally Advanced Pancreatic Cancer
A prospective, nationwide, implementation program of the international standard of excellence for locally advanced pancreatic cancer (LAPC) care in the Netherlands (2021[7]-2030[6]), including a multidisciplinary training program by the four leading international expert centers. The PREOPANC-4 project aims a safe and patient-centered implementation of the international standards of excellence for …
Disease Outcomes and Toxicities in Patients With Gastrointestinal and Sarcomatous Malignancies
This prospective, single-institution, observational study explores disease outcomes and toxicities in subjects with gastrointestinal malignancies and sarcoma (bone and soft tissue) who are being treated with standard-of-care therapies including radiotherapy. Recent advances in treatment approaches affected disease outcomes and toxicities. Prospective monitoring of disease outcomes and toxicities using standardized assessments …
Management of Malignant Gastric Outlet Obstruction Between Surgery and Endoscopy
The aim of this observational study is to compare the outcomes of three different procedures performed for the management of malignant Gastric Outlet Obstruction due to Pancreatic Cancer. Patients who undergo: Surgical gastroenterostomy Endoscopic placement of a self-expanding metallic stent EUS-guided gastroenterostomy in accordance with standard clinical practice, will be …
Bile Omics for Diagnosing Indeterminate Biliary Strictures
The diagnosis of malignant biliary strictures remains a challenging aspect of biliary endoscopy. Molecular biological testing techniques based on bile have been reported to improve detection rates. However, whether the combination of bile-based omics studies and biliary brush cytology/biopsy can enhance diagnostic sensitivity has not yet been reported. This study …
