Filter by:This clinical trial studies the effect of cancer directed therapy given at-home versus in the clinic for patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Currently most drug-related cancer care is conducted in infusion centers or specialty hospitals, where patients spend many hours a day isolated from family, friends, and familiar surroundings. This separation adds to the physical, emotional, social, and financial burden for patients and their families. The logistics and costs of navigating cancer treatments have become a principal contributor to patients' reduced quality of life. It is therefore important to reduce the burden of cancer in the lives of patients and their caregivers, and a vital aspect of this involves moving beyond traditional hospital and clinic-based care and evaluate innovative care delivery models with virtual capabilities. Providing cancer treatment at-home, versus in the clinic, may help reduce psychological and financial distress and increase treatment compliance, especially for marginalized patients and communities.
To provide preventive and therapeutic strategies for participants with gallstones after gastric cancer by comparing the risk of postoperative gallbladder stone formation with two different resection ranges using the Roux-en-Y reconstruction modality in radical gastric cancer surgery.
ECDNA is almost non-existent in normal cells, but exists in nearly half of human cancer cells, indicating that studying such abnormal DNA is of great significance for our understanding of tumor formation and evolution. The changes in ecDNA expression in intestinal type gastric cancer may be closely related to the occurrence and development of gastric cancer. Dynamic monitoring of changes in ecDNA expression in the gastric mucosa may help predict the occurrence of gastric cancer and guide subsequent treatment. By collaborating with multiple endoscopic centers to conduct gastroscopy biopsies on patients with gastric precancerous lesions, we aim to further explore the role of ecDNA in the occurrence and development of gastric cancer through continuous follow-up.
The goal of this clinical trial is to test a new PET tracer in patients with HER2-positive breast or gastric cancer. This tracer is made of radioactively labeled trastuzumab, and can show where HER2 is present in the body using a PET-scan. For this research, the investigators make PET-scans in people with HER2-positive, metastasized breast- or gastric cancer. The investigators will investigate if the new HER2-tracer correctly shows all tumor lesions. In the future, this method may be useful to help predict who will benefit from certain HER2-directed therapies. Participants will be injected with the radioactive tracer once. After injection, participants will undergo 3 PET-scans. Each PET-scan will take a maximum of 60 minutes. The PET-scans are on separate days within a week after injection of the tracer (e.g. 1 day, 2 days and 4 days after injection). Furthermore, the investigators will take 7 blood samples (5 mL each). Participants are not required to stay at the hospital. The first 3 participants will undergo an extra PET-scan 1 - 2 hours after injection. The amount of radioactivity injected will be 37 MBq (± 10%).
The purpose of this trial is to evaluate a new drug, HTL0039732, that will be administered on its own (as a monotherapy) and in combination with atezolizumab or with other approved anti-cancer therapies, in participants with advanced solid tumours.
Endoscopic submucosal dissection (ESD) is the technique that has replaced surgery in the treatment of early neoplastic lesions of the stomach (LNPS). ESD of LNPS allows: a) less invasiveness compared to surgery; b) greater chances of "en bloc" resection and R0 resection compared to mucosectomy for lesions larger than 15 mm. Recent 2015 ESGE guidelines provide precise recommendations for the use of ESD in the treatment of LNPS, but Italy lacks prospective data on the efficacy and safety of ESD in a large sample of patients. A multicenter prospective observational study to create a database on the use of ESD in LNPS is essential to provide information regarding the efficacy and safety of ESD in Italy. This database would also provide information regarding the criteria applied in the use of ESD in the treatment of early gastric neoplasia
Upper gastrointestinal (GI) cancers are one of the most common cancers worldwide. Except for cardia cancers, the incidence of gastric cancer has decreased consistently since 1980, but remains at a high level. In France, gastric cancers are the 6th most common cause of cancer-related mortality. The risk factors of upper GI cancers are well known and their control could prevent the development of cancers: smoking cessation, reduction of obesity, alcohol, eradication of Helicobacter pylori. But late presentation with upper GI cancer results in a poorer prognosis. Patients with advanced (Stage IV) gastric cancer have a five-year survival rate of 3.7% whereas patients whose gastric cancer is discovered in its early stage (Stage I) have a significantly higher five-year survival rate of 88.4%. Therefore, endoscopic detection of upper GI lesions at an earlier stage is the single most effective measure for reducing cancer mortality. But upper GI cancer is also often missed during examinations, and some studies demonstrated a missed cancer rate of 2.3-13.9% in Western populations. In the past decade, accurate diagnosis during endoscopy has become particularly important as dysplastic lesions and early gastric cancers can be treated effectively with both endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), avoiding the morbidity and mortality associated with gastrectomy. However, these early neoplastic lesions can be sometimes difficult to distinguish from background mucosa, even with advanced imaging techniques (high definition, chromoendoscopy). In recent years, image recognition using artificial intelligence (AI) with deep learning has dramatically improved and opened the door to more detailed image analysis and real time application in various medical field, including endoscopy. For example, in the colorectal cancer screening area, real time computer-aided detection systems (CADe) can lead to significant increases in both polyp and adenoma detection rates. CADe has also shown good performance in detection of Barrett's neoplasia during live endoscopic procedures in order to more accurately locate the area to be biopsied. Recently, a Chinese study showed that CADe achieved high diagnostic accuracy in detecting upper GI cancers, with sensitivity similar to that of expert endoscopists and superior to that of non-experts. This system could support non-experts by improving their diagnostic accuracy to a level similar to that of experts and provide assistance for improving the effectiveness of upper GI cancer diagnosis and screening. Although encouraging results have been published regarding the use of AI in the diagnosis of upper GI cancers, the clinical applicability of such systems in a European population has yet to be investigated. Therefore, we want to evaluate the diagnostic capability of a recent CADx compared to endoscopists in order to improve the real-time detection of early gastric cancers in our European center Edouard Herriot Hospital, Lyon, France, as well as 3 other tertiary centers in France (Limoges, Rennes and Nancy University Hospitals). With a high prevalence of stomach cancer, Japan is a world leader in high-quality diagnostic upper GI endoscopy, and the clinical routine in this country differs substantially from Western practice, with population-based screening programs. We will use for our study a CADx developed by AI medical service Inc. (1-18-1, Higashiikebukuro, Toshima-ku, Tokyo 170-0013, Japan), a Japanese company developing AI systems that supports endoscopist's diagnosis for the digestive tract. A recent study involving AI medical service system showed good results in the diagnosis of early gastric cancer compared to endoscopists, with a significantly higher sensitivity.
The goal of this clinical trial is to determine if FOG-001 is safe and effective in participants with locally advanced or metastatic cancer.
This is a randomized, controlled, multicenter phase Ⅲ study to evaluate the therapeutic efficacy of modified XELOX plus sintilimab versus standard XELOX plus sintilimab in subjects with advanced HER2-negative gastric or gastroesophageal adenocarcinoma in the first-line treatment. The primary outcome is the progression-free survival (PFS), with a planned enrollment of 540 subjects.
This clinical trial evaluates the feasibility and acceptability of acupressure to the ear (auricular) to address appetite and weight in patients with stage II-IV gastric, esophageal, or pancreatic cancer. Cancer anorexia, the abnormal loss of appetite, directly leads to cancer-associated weight loss (cachexia) through malnourishment, reduced caloric intake, treatment side-effects, and other modifiable risk factors. Cachexia prolongs length of hospital stay for patients, negatively impacts treatment tolerance and adherence, and reduces overall patient quality of life. Auricular acupressure is a form of micro-acupuncture that exerts its effect by stimulating the central nervous system using adhesive taped pellets applied to specific locations on the external ear. The use of these pellets to deliver auricular acupressure has been shown to improve pain, fatigue, insomnia, nausea and vomiting, depression, and quality of life in both cancer and non-cancer settings. Auricular acupressure is a safe, inexpensive, and non-invasive approach to addressing cancer-related symptoms and treatment side-effects and may be effective at improving appetite and weight loss in stage II-IV gastric, esophageal, and pancreatic cancer patients.
