Filter by:To explore the effect of different doses of vitamin D drugs on gastrointestinal cancer cancer-related cognitive impairment, so as to provide reference and basis for the clinical use of our cognitive function surgery nursing plan for patients with gastrointestinal cancer.
Postoperative cognitive dysfunction(POCD). is a central nervous system complication in cancer patients with a 8.9-46.1% incidence. It is mainly manifested as impaired memory, descending information handling ability and decline or damage of attention, perception, abstract thinking, executive, language, and body movement. However, it is difficult to identify and it can last for months or years or even become a dementia state, which can severely affect patients' postoperative recovery, prolong the hospitalization time, reduce the quality of life, increase the mortality and the consumption of family and social medical resources, and intensifies the national economic and social burden. Transcutaneous electrical acupoint stimulation (TEAS) is a new type of acupoint stimulation therapy that inputs low-frequency pulse current into human acupoints through electrodes pasted on the skin surface to achieve therapeutic purposes, which combined the preponderances of both acupuncture and transcutaneous electrical nerve stimulation (TENS). TEAS is non-invasive, easy to operate and acceptable to patients. Study showed that TEAS treatment can reduce the consumption of intraoperative anesthetic and improve postoperative nausea and vomiting (PONV) and postoperative recovery. Also, studies have shown that TEAS treatment may improve the cognitive function of geriatric patients. Most studies have shown that TEAS treatment 10~30 minutes before operation or from entering the operating room to the end of operation can reduce the incidence of POCD in elderly patients. Some studies showed that preoperative combined with postoperative or simple postoperative TEAS treatment can significantly improve patients' postoperative cognitive function. Our previous research showed that perioperative TEAS treatment can reduce the postoperative inflammatory response and increased the postoperative cognitive function score and decrease the incidence of POCD in geriatric patients with gastrointestinal tumor. Moreover, studies showed that long-term electroacupuncture treatment is easy to cause "tolerance effect', leading to the activation of the negative feedback mechanism of the body, and reduction of the number of receptors, and the weakening of the treatment effect. So, what is the best time period for TEAS to improve POCD and reduce the use of resources? Therefore, the objective of this study is to discuss different time of TEAS on POCD in geriatric patients with gastrointestinal tumor.
This is a prospective, open, single-arm Phase II clinical study to evaluate the efficacy and safety of anti-PD-1 antibody combined with autologous DC and NK cells in the treatment of digestive carcinoma.
The purpose of this study is to compare the similarities and differences of 99mTc-FAPI quantitative SPECT/CT and 68Ga-FAPI PET/CT in the diagnosis and staging of gastrointestinal tumors, and clinical diagnosis and economic value of 99mTc-FAPI quantitative SPECT/CT for the gastrointestinal tumors.
To explore the value of PTC drug screening technique in selecting neoadjuvant therapy for advanced gastrointestinal cancer.
This study intends to explore the effectiveness and safety of CDK4/6 inhibitor (TQB3616) combined with PD-L1 monoclonal antibody (TQB2450) in the treatment of PD-1/PD-L1 monoclonal antibody resistance and abnormal cell cycle digestive system tumors, through prospective Explore to provide more evidence-based medical evidence for precision immunotherapy for patients with digestive system tumors.
This is an open-label，multi-center ，non-randomized ，single arm exploratory study . This clinical study is an investigator-initiated clinical trial（IIT ）. The objective of this study is to evaluate if the addition of hepatic artery infusion chemotherapy (HAIC) and Donafenib after curative resection for hepatocellular carcinoma patients with a solitary tumor≥5 cm and microvascular invasion （MVI） will prevent or delay the recurrence of the disease.
Chimeric Antigen Receptor T Cells (CART) Therapy in GUYC2C postive Digestive system tumors, include colorectal cancer, gastric cancer, liver cancer, pancreatic cancer, adenocarcinoma of esophagus, cancer of the esophagogastric junction. Ict-gc is an open, single-center study to evaluate the safety and efficacy of CAR-T-targeted therapy in patients with advanced gastrointestinal tumors.
Gastrointestinal cancer like Gastric cancer and colorectal cancer are high-incidence tumors worldwide. Surgery is the only curable way. Perioperative treatment can improve the survival of patients. Microsatellite instability-high（MSI-H）are a special subtype of gastrointestinal tumors, accounting for about 15-22%. According to current research, patients with this type of gastrointestinal tumors cannot benefit from traditional perioperative chemotherapy, which directly affects the long-term survival of patients. Because patients with MSI-H have a unique tumor immune microenvironment, thus they are more likely to benefit from immunotherapy. Current studies have confirmed that the use of immunotherapy during palliative care can prolong the survival of patients with MSI-H. In the neoadjuvant treatment stage, according to the previous clinical practice of our center, the use of immunotherapy can make some patients achieve complete postoperative pathological remission. However, in the perioperative treatment stage, the value of immunotherapy is still lack of powerful clinical evidence. Based on this, our group intends to start an observational study to prospectively enroll patients with MSI-H gastrointestinal tumor using immunotherapy during the perioperative period.The primary endpoint is safety while survival outcomes as secondary endpoints. In order to evaluate the safety and effectiveness of immunotherapy during the perioperative treatment stage in MSI-H gastrointestinal cancer
This clinical study focused on patients with digestive system tumors resistant to PD-1 inhibitors, and explored the reversal resistance of epigenetic drugs (decitabine) and TKI drugs (anlotinib) in this part of patients.
