Filter by:The clinical study of modern therapies on flora changing in blood, oral cavity, urethra and intestinal tract of patients with malignant tumors. The study is observational. Patients are diagnosed cancer based on pathology or cell biology. The sample of flora will be obtained from their blood, oral cavity, urethra and intestinal tract, mainly to study what modern therapies lead to the influence of microecological environment including diversity and abundance of bacteria in patients who received malignant tumors. Immunological examination and Blood biochemistry evaluation include the number ratio, activity and function of immune cell, the immune cell marker(CD3, CD4, CD8, etc), C-reactive protein(CRP), tumor necrosis factor(TNF), Inflammatory stimulant factor(IL-2, IL-6, etc), tumor marker(CEA, AFP, etc),etc. Clinical evaluation includes image data(CT/MRI), quality of life(QOL), no disease progression survival, total survival, objective disease remission rate, etc.
The MA-PPING is a multicenter prospective observational study that includes patients undergoing surgery for gastrointestinal cancer. The study aims to map the oral and gut microbiome of patients diagnosed with pancreatic, esophageal or colorectal cancer during their surgical patient journey from the moment of diagnosis until full recovery (three months after surgery).
The research studies patients with advanced gastrointestinal cancer who receive chemotherapy in the medical oncology department of the First Affiliated Hospital of Xian Jiaotong University. All patients receive the nutritional risk assessment by the nutritional support team first, and patients with nutritional risk or malnutrition are randomly assigned to the study group and the control group. The study group receive nutritional intervention from the nutritional support team during the period of chemotherapy, while the control group receive routine nutritional support from their clinicians. In the control group, nurses execute the doctors' advice on nutrition, and the nutrition support team does not actively communicate with doctors about the nutritional risk of patients or interfere with it. The baseline characteristics, chemotherapy efficacy, adverse events and prognosis are collected in both groups. At last, data are analyzed to clarify the nutritional status and related factors of patients with advanced gastrointestinal cancer in our hospital, and most important to explore the effect of nutrition-support-team intervention on nutritional status, chemotherapy tolerance and prognosis of patients with advanced gastrointestinal cancer.
Liquid biopsy has been successfully applied to the treatment and diagnosis of cancer. cfDNA has been paid more and more attention in liquid biopsy. Previous studies have shown that cfDNA can be used for predicting the efficacy of radiotherapy or chemotherapy for lung cancer, rectal cancer and esophageal cancer. It is also reported that cfDNA can be used for the evaluation of postoperative recurrence of advanced gastric cancer. However, the use of NGS to detect cfDNA in gastrointestinal tumors has not been reported. The purpose of this study is to investigate the correlation between cfDNA, cfDNA tumor buden with advanced gastrointestinal tract tumor patients, and find out prognosis gene of advanced gastrointestinal tract tumor.
This is an open-label study to evaluate the safety and efficacy of an anticancer medication (A01) combined with immune cells (IC01) in subjects with advanced Gastrointestinal cancer.
To research the effect of propranolol on the proliferation and apoptosis of gastrointestinal cancer.
