Filter by:This study collects information about the safety and effect of portal vein stenting in gastrointestinal cancer patients with portal vein stenosis. This study may help researchers learn how long the portal vein stays open and free from blockage and the effects of portal vein stenting on patients' overall well-being.
The objective of the study is to constrcut a noninvasive approach WL12 PET/CT to detect the PD-L1 expression of tumor lesions in patients with gastrointestinal tumors and to identify patients benefiting from anti-PD-1/L1 treatment.
This is a single-center, open-label, single-arm phase I clinical study to exploratory observe and evaluate the efficacy and safety of anti-PD-1 antibody (Camrelizumab for Injection) combined with multisite stereotactic ablative radiotherapy (SABR) in patients with oligometastatic gastrointestinal cancer. According to the origin site of metastases, this study will consist of three subgroups, including gastric carcinoma group, colorectal carcinoma group and hepatocellular carcinoma group. For each of the subgroup, seven eligible patients with oligometastatic cancer originating from stomach, colon and liver, respectively will be recruited. All patients will receive multisite SABR followed by immunotherapy of Camrelizumab within one week from completion. Camrelizumab will be administered at a fixed dose of 200 mg intravenously (iv) on D1 in a 14-day cycle. The treatment will continue for up to two years until disease progression, unacceptable toxicity or patient withdrawal. Tumor tissue samples, sections, paraffin blocks or biopsy blocks, and biomarkers, including but not limited to PD-L1 expression level and the proportion of positive cells, TMB level and MMR status, will be collected from subjects.
This is a prospective, open, phase I clinical study to evaluate the safety and tolerability of a CDK4 / 6 inhibitor and a MEK inhibitor in the treatment of metastatic digestive system tumors
This study is an open, multi-center clinical trial, the purpose is to study the safety and preliminary efficacy of Donafenib combined with KN046 in subjects with Advanced Gastrointestinal Tumors.
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.
This is a multi-cohort proof of concept study involving patients with metastatic gastrointestinal cancers. In the first cohort of treatment-naïve patients, the investigators intend to create cancer organoids for 100 subjects. Then, the investigators intend to evaluate ex-vivo prediction of treatment outcomes using QPOP (see section 4.0 for detailed sample size calculation). Patients enrolled on study will undergo a fresh biopsy of tumour lesion to obtain cells that will be used to generate patient-derived tumour organoids. These patients will go on to receive standard of care first-line chemotherapy +/- targeted therapy. Organoids will then be subjected to up to a 14-drug panel screening. The drugs in the respective drug panel have been shown to have activity in the respective cancers and would be used in the standard-of-care setting by treating physicians.
The purpose of this study is to learn about the impact of the Oncology Nurse Navigation program on the frequency of Emergency Department, urgent care visits and inpatient hospital admissions; and overall survival rate at 6 months. The investigators aim to understand if prompt and effective coordination of care provided by Oncology Nurse Navigation (ONN) service will reduce the number of avoidable, unplanned ED visits and hospitalizations, as well as adding measurable value to cancer care, and improve patient overall survival.
This multicenter, prospective, interventional study aims to include 2000 gastroscopic procedures and investigate the relationship between procedure time and lesion detection rate in tertiary endoscopic centers in China. At the first stage, the researchers observe the actual procedure time of gastroscopies without affecting the natural behavior of endoscopists. At the second stage, a minimal time limit will be set for each procedure based on the observational results of the first stage. The primary study outcome is focal lesion detection rate. Secondary outcomes include detection rate of early upper GI cancer, biopsy rate and adverse event rate.
The study is going to recruit patients with gastrointestinal cancer, collect clinical data and peripheral blood sample and possible fat samples. The expression of SIRT-6 in peripheral blood will be tested and connect with different status of cachexia of the patients. A mathematical model of the relationship between cachexia classification and SIRT-6 expression is going to constructed as anticipated.
