Filter by:Clinical Decision Support Systems (CDSSs) to augment clinical care and decision making. These are platforms which aim to improve healthcare delivery by enhancing medical decisions with targeted clinical knowledge, patient information, and other health information. In view of the benefit of developing a CDSS, we sought to develop an alternative CDSS for oncologic therapy selection through a partnership with Ping An Technology (Shenzhen, China), beginning with gastric and oesophagal cancer. This would be done in a piecemeal fashion, with the prototype platform utilizing only international guidelines and high-quality published evidence from journals to arrive at case-specific treatment recommendations. This platform would then be evaluated by comparing its recommendations with that from the multidisciplinary tumour boards of several tertiary care institutions to determine the concordance rate.
Because advanced gastric cancer shows poor prognosis, it is important to detect early gastric cancer or precancerous gastric adenoma patients who have a cure rate of 95% or more. Moreover, a large part of early gastric cancer can be completely resected by endoscopic resection, thus ensuring a very high quality of life for patients. However, there are currently no markers that can be used for diagnosis of early gastric cancer or gastric adenoma. In addition, the biggest problem after endoscopic resection of early gastric cancer is metachronous recurrence of the cancer, which requires repeated endoscopic resection or additional surgical gastrectomy. However, there are no discovered markers for prediction of recurrence. Liquid biopsy is a method of obtaining body fluids such as gastric juice or effusion through an endoscopic inlet during gastroscopy or colonoscopy and blood. Based on the advanced analysis method, liquid biopsy reveals more genetic information than tissue biopsy. Therefore, it is highly likely to become an essential factor in future personalized medicine. Therefore, this study was designed to identify whether tumor's molercular profiling based on tissue or blood could be used for prediction of prognosis and diagnosis of early gastric cancer and precancerous gastric adenoma.
This phase II trial studies the effect of the combination of ramucirumab and trifluridine/tipiracil or paclitaxel in treating patients with previously treated gastric or gastroesophageal junction cancer that has spread to other places in the body (advanced). Ramucirumab may damage tumor cells by targeting new blood vessel formation. Trifluridine/tipiracil is a chemotherapy pill and that may damage tumor cells by damaging their deoxyribonucleic acid (DNA). Paclitaxel may block cell growth by stopping cell division which may kill tumor cells. Giving ramucirumab and trifluridine/tipiracil will not be worse than ramucirumab and paclitaxel in treating gastric or gastroesophageal junction cancer.
A prospective study of the results of laparoscopic approach of gastric carcinoma in western patients is designed. The working hypothesis proposes obtaining similar results to those obtained in the series reported by eastern hospitals (Japan and Korea) and, at least, equivalent to those recorded in conventional surgery.
The study was designed to evaluate the effectiveness of the maximum dose of mucolytic solution used before upper endoscopy on the visibility of the gastric mucosa
In this clinical trial, we aim to explore the synergistic alteration of specific bacteria both in gastric mucosas and feces of gastric cancer patients for the method of non-invasive and cost-effective faecal marker detection. We aim to select and validate specific microbes as noninvasive, accurate, simple, sensitive and highly-accepted biomarkers that might assist to screen and diagnose gastric cancer, especially early gastric cancer patients.
1. Objective 1) Primary Objective: To estimate preliminary overall response rate (ORR) of combination therapy of Ramucirumab and Pembrolizumab in patients with metastatic gastric or GEJ adenocarcinoma 2)Secondary Objectives: To assess secondary measures of clinical efficacy - Best Overall Response Rate: BORR - Disease Control Rate: DCR - Progression-Free Survival:PFS - Overall Survival: OS - Duration of Overall Response: DOR & maximal tumor shrinkage 2. Subjects : Patients with metastatic gastric or GEJ adenocarcinoma 3. Study design(Dosage & Treatment) Patients will continue to receive study treatment, until they demonstrate objective disease progression (determined by modified RECIST 1.1) or until they meet any other discontinuation criteria. - Ramucirumab 8mg/kg on q2W - Pembrolizumab 200mg on q3W (pembrolizumab first followed by ramucirumab when concurrently administered on the same day) - If ramucirumab had to be stopped due to intolerable toxicity, pembrolizumab will be continued until unacceptable toxicity, disease progression or upto 35 cycles.
The pathogenetic mechanisms of chronic gastritis and gastric carcinoma are different. Whether metabonomics play a role in the development of chronic gastritis and gastric cancer is still a question. So the investigators want to clarify this question by this subject.
Subepithelial lesions (SEL) are incidentally observed in the stomach of about 0.3% of middle-aged men and women; half of these are neoplastic. The incidence of subepithelial tumors (SET) of gastrointestinal (GI) origin has risen twofold to fivefold within the past 30 years.The etiology of most SMTs cannot easily be determined by endoscopy. So, we aim to estimate the prevalence and types of sub-epithelial lesions among patients undergoing EGDs in Egypt.
The purpose of this study is to enhance the care of older metastatic gastric cancer (mGC) patients by increasing awareness among oncology providers of the unique aspects of care required for older patients. The goal of the study is to educate providers on the utility of geriatric assessment in guiding therapy of older mGC patients. The investigators will also assess the feasibility and benefit of incorporating geriatric self-assessments into clinical practice. The study will include four phases.
