Active clinical trials for "Stomach Neoplasms"

The objective of this Study is to collect, process, and transfer biologic samples such as blood and/or tissue biopsies to determine the concordance of detected alterations obtained through liquid biopsy analyses compared to next generation sequencing of time-matched or archival tissue specimens from individuals with advanced solid tumors. Examples of locally advanced and metastatic tumors include stage III and IV cancers (ex. lung, breast, all gastrointestinal malignancies, all gynecologic malignancies, prostate cancer, head and neck tumors, soft tissue cancers, and melanoma). These specimens will be analyzed for diagnostic purposes and research (either by Labcorp/OmniSeq or to a third-party recipient designated by Labcorp/OmniSeq). Labcorp/OmniSeq may transfer the specimens and data to its clients, including commercial, academic or non-profit research institutions; or alternatively, may retain the specimens in its repository for future research use at the sole discretion of Labcorp/OmniSeq and or assignees. Labcorp/OmniSeq will maintain all detailed clinical information including demographic data (de-identified), ethnicity, disease state, stage (radiological, pathological and clinical-whichever is relevant).

Peritoneal metastasis of gastric cancer is difficult to be detected in time, thus delaying treatment. Based on the conventional CT images of gastric cancer, this study plans to develop, improve and validate an intelligent analysis system based on radiomics. By extracting and combining the radiomics features related to peritoneal metastasis of gastric cancer, the intelligent analysis system could predict the risk of peritoneal metastasis, and provide personalized decision suggestions for the treatment of gastric cancer.

It is well known that the prevalence of malnutrition or risk of malnutrition in cancer patients is high, as well as its impact on different parameters such as hospitalization, survival or response to certain treatments. In patients with gastroenteropancreatic (GEP) neuroendocrine tumors (NET), due to their heterogeneity and longer survival, it is expected that the prevalence of malnutrition is probably underdiagnosed, as well as the existence of a negative impact on different parameters (quality of life, survival). So far, the studies carried out on nutrition and NET are very scarce and none has been carried out so far in Spain. Before being able to carry out nutritional intervention studies on these patients, it is necessary to know the reality of the nutritional status of patients with NETs in Spain. The main motivation for the NUTRIGETNE study is to evaluate the epidemiological status of nutrition in NETs in the spanish population. In addition to know the epidemiological picture, it is intended to study the nutritional status from different points of view: analytical, clinical, anthropometric, etc. Besides, the study of nutritional status will allow us to closely monitor the patients who have a higher risk of malnutrition and to propose early interventions for those, as well as the impact of their nutritional status on different parameters: survival, hospitalization, quality of life or responses to the treatments. NUTRIGETNE is a cross-sectional, open and multicenter study in which the nutritional status of patients with GEP NET in Spain will be evaluated.

Our research of the biology of upper gastrointestinal cancers involves the study of tissue samples and cells from biopsies of persons with gastric or esophageal cancer or blood samples from upper gastrointestinal cancer patients and persons at high inherited risk for these cancers. We hope to learn the role genes and proteins play in the development of gastric and esophageal cancer.

This is a multi-center prospective case control study aiming to compare different methods of risk stratification models in predicting the risk of gastric cancer development.

This protocol is a single-institution feasibility study to identify the molecular and epidemiological risk factors in the development of gastric cancer in high-risk predominantly Hispanic South Texas population. The study is broken down into two main parts: 1) To identify molecular differences in gastric adenocarcinoma (GAC) between Non-Hispanics and Hispanics, stratified by age, and in benign, pre-malignant, and malignant gastric lesions; and 2) To identify environmental and clinicopathological factors in Hispanics associated with specific molecular changes linked to the development of GAC.

The study is aimed to determine the potential of volatile marker testing for gastric cancer screening. The study will be addressing the role of confounding factors, including lifestyle factors, diet, smoking as well as addressing the potential role of microbiota in the composition of exhaled volatile markers.

Database of Institut Paoli-Calmettes patients diagnosed with cardia cancer

This was a case control, non-intervention study jointly developed by Fudan University Cancer Hospital and Shanghai Singlera Genomics Company. The enrolled population was screened by gastric surgery, including gastric cancer, precancerous lesions, benign lesions, and healthy control group. 10ml of whole blood of the enrolled subjects was collected for multi-target PCR detection of cfDNA methylation. The objective is to explore the clinical performance of polygene methylation (PCR-fluorescence probe) in the adjunctive diagnosis of gastric cancer, including the sensitivity of detection of various types and stages of gastric cancer, the specificity of detection of healthy controls, precancerous states, precancerous lesions, and the detection interference of other cancers. The diagnostic performance will be compared with CA199, CEA and CA724. The research data will provide a basis for screening targets for the development of detection kits.

This study collect the relevant data of local residents over 20 years old in 11 regions of Shaanxi Province, The basic information of the subjects was collected by filling in the questionnaire, and serum helicobacter pylori antibody detection was completed at the same time. The expert group determined the high-risk population of gastric cancer after comprehensive evaluation. All the high-risk population of gastric cancer without contraindications underwent electronic gastroscopy in the designated hospital after signing the informed consent. By collecting and analyzing data, early gastric cancer screening was completed and a new gastric cancer risk assessment model was established to evaluate the prevalence of dyspepsia, gastroesophageal reflux disease and precancerous lesions in the natural population of Shaanxi Province, as well as helicobacter pylori infection, radical treatment and recurrence rate.
