Active clinical trials for "Digestive System Neoplasms"

The purpose of this single center prospective study is to assess the value of FAPI PET imaging in predicting early postoperative recurrence of malignant tumor of digestive system and to evaluate the diagnostic performance of FAPI PET/CT in the detection of primary tumor and metastatic lesions.

Observational prospective cohort study designed for patients with gastrointestinal cancers receiving a fluoropyrimidine based chemotherapy regimen.

To establish combined gastroenteroscopy screening and follow-up management for gastrointestinal tumors, explore and evaluate the feasibility and health economic benefits of combined screening for esophagus, stomach and colorectal cancer

This study aims to validate and evaluate AI algorithms for detection and characterization of early GI neoplasia.

To evaluate clinical outcome for patients receiving treatment of suspected premalignant and malignant gastrointestinal lesions at Interventional Endoscopy Services. The primary outcome is curative endoscopic resection. Secondary outcomes include resection technique utilized, rates of en bloc resection and adverse event rates, including infection, bleeding, perforation and death, and one-year survival rates.

PET has an established role in the initial staging of patients with newly diagnosed lung and gastrointestinal tumors.PET avidity is described with both maximum and mean standardized uptake values.Malignant cells have increased activity on PET, defined as the standardized uptake value (SUV), with increased uptake of FDG in tumor due to elevated levels of GLUT receptors, elevated intracellular levels of hexokinase and increased rates of glycolysis. However, there is a subset of patients with lung and gastrointestinal tumors that are not PET avid.These patients may present with clinically and systemically aggressive disease with a declining performance status and/or weight loss.

Phase 3 placebo-controlled trial to determine efficacy of the probiotic LGG for reducing acute treatment related GI toxicity in patients with GI malignancy with phase 1 safety lead-in.

This study will include two parts: In the phase I part: safety will be assessed in consecutive cohorts of 3 to 6 patients at increasing doses of TG6002 in combination with oral flucytosine (5-FC) in patients with advanced gastro-intestinal (GI) tumors. In the phase IIa part: evaluation of efficacy and further evaluation of safety of multiple administrations of TG6002 in combination with flucytosine (5-FC) in patients with colorectal cancer and liver metastases. In both parts, tumor response will be evaluated on local assessment using RECIST 1.1. All patients will be followed up until disease progression or death due to any cause or the date of data cut-off, whichever occurs first.

The purpose of this study is to explore the efficacy and safety of everolimus administered as a first-line treatment in newly-diagnosed patients with advanced or inoperable Gastrointestinal (GI) or pancreatic neuroendocrine tumors.

Investigators intend to utilize clinical data from the Department of Oncology at Jiangsu Provincial People's Hospital to analyze changes in body composition in digestive system tumor patients before and after receiving anti-tumor drug treatment. Investigators aim to uncover the association between baseline body composition and overall/progression-free survival in patients with digestive system tumors. Additionally, Investigators plan to investigate the relationship between changes in body composition during anti-tumor drug treatment (chemotherapy and immunotherapy) and the prognosis of tumor patients.
