Filter by:The purpose of this study is to determine the safety, tolerability, and preliminary efficacy of INCAGN02390 in participants with select advanced malignancies.
A Phase 1b, open-label, dose escalation study of PRS-343 in combination with atezolizumab in patients with HER2-positive advanced or metastatic solid tumors.
Background: People with hereditary gastric cancer syndrome are at increased risk of getting cancer in their stomach. These people should have regular endoscopies and biopsies to check for cancer if they are choosing to keep their stomach. Researchers want to see if they can improve the detection of cancer by endoscopy. Improved endoscopies could better detect early signs of cancer in people with this syndrome. Objective: To see if a small microscope attached to an endoscope to inspect the stomach lining is better than regular endoscopy to find the first signs of cancer in the stomach. Eligibility: People ages 18 and older who have a personal or family history of a hereditary gastric cancer syndrome or have a mutation that is known to lead to gastric cancer Design: Participants will be screened over the phone or in person with: - Personal and family medical history - Review of their medical records Participants will have a physical exam. Then they will be put under general anesthesia. They will have an endoscopy. A lighted tube will be inserted into the mouth and go down to the stomach. First, the standard device will be used. Then participants will be injected with fluorescein. This is a contrast agent. Then the microscope will be added to the tube and the endoscopic evaluation of the stomach will be repeated. During the procedure, biopsies will be taken from different areas of the stomach. Participants will be observed for a few hours after the procedure. About 14 days after the endoscopy, participants will be asked to return to the clinic for a follow-up visit. This visit can also be conducted over the phone.
Neoadjuvant chemotherapy for advanced-stage gastric cancer is justified by various studies, however, there was not any large scale randomized controlled trial (RCT) to support it until German oncologist introduced a novel regimen(FLOT regimen) in 2017. Investigator assessed the FLOT regimen for safety and feasibility in Chinese gastric cancer patients.
The purpose of this study is evaluate the pharmacokinetics, pharmacodynamics, immunogenicity and anti-tumor effect of of fully human anti - VEGF monoclonal antibody LY00101 and explore the potential prognostic and predictive biomarkers. This study will not take into account the results of molecular-genetic tests of patients enrolled in the study
A one-group prospective cohort study design with measures collected pre- and post-intervention. The primary goal of this study is to evaluate the effect of a multimodal prehabilitation preoperative program on changes in frailty in upper gastrointestinal surgical oncology patients.
This phase II trial studies the how well berzosertib and irinotecan work in treating patients with gastric or gastroesophageal junction cancer that is growing, spreading or getting worse (progressive), has spread to other places in the body (metastatic), or cannot be removed by surgery (unresectable). Berzosertib may stop the growth of tumor cells by blocking some of the enzymes needed for growth. Chemotherapy drugs, such as irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving berzosertib and irinotecan may work better than irinotecan alone in treating patients with gastric and gastroesophageal junction cancer.
An objective analysis of postoperative complications is vital to escort octogenarian for gastric cancer surgery. Investigator carefully collected clinical data prospectively to pave way for standard management in high risk patients.
Safety and efficacy study of neoadjuvant chemotherapy (FLOT versus SOX) for gastric cancer patients in high volume center of China
Early gastric cancer is defined as gastric cancer that only invades mucosal or submucosal layer. The 5-year survival rate of gastric cancer can exceed 90% due to appropriate treatment. The most important consideration is whether there is lymph node metastasis. Preoperative examination including gastroscopy, endoscopic ultrasonography (EUS) and CT are not accurate enough to predict lymph node metastasis in early gastric cancer. In a retrospective study, we created a nomogram to predict lymph node metastasis in early gastric cancer. In prospective validation, the sensitivity and specificity of the nomogram was 75% and 91%, respectively. Sentinel lymph node is a promising concept in early gastric cancer. Using carbon nanoparticles as tracer, the sensitivity and specificity of sentinel lymph node predicting lymph node metastasis in early gastric cancer were 90% and 100%. Based on these results, we proposed a new method that combines the Nomogram and sentinel lymph node to predict lymph node metastasis in early gastric cancer. First, the probability of lymph node metastasis of early gastric cancer patients is calculated by the Nomogram. Those with low incidence of lymph node metastasis continue to the sentinel lymph node procedure. A patient will be considered non lymph node metastasis if his/her frozen pathology of the sentinel lymph nodes is negative during the surgery. Then the standard radical gastrectomy is performed with lymphadenectomy. By comparing postoperative pathology and sentinel lymph node frozen pathology, the specificity of Nomogram combining sentinel lymph node predicting lymph node metastasis in early gastric patients is calculated. The primary endpoint of this research is that the specificity of the above-mentioned method is over 95%.
