Filter by: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.
Introduction: Gastric atrophy and intestinal metaplasia are the principal precursors for gastric cancer and, therefore, are considered gastric premalignant conditions. Although current guidelines recommend surveillance of individuals with these conditions, the best method for its identification and staging (histological vs endoscopy) and the best time schedule for follow-up are still controversial. Aims: To describe for the first-time patients with premalignant conditions both clinically (familial history), histologically (OLGA/OLGIM; complete/incomplete metaplasia) and endoscopically (EGGIM) using validated scales and to describe evolution of these parameters through time. To estimate prospectively the gastric cancer risk according to EGGIM stages. To define the best endoscopic surveillance follow-up for the several stages considering clinical, histological and endoscopic factors. Methods: Multicenter study involving different gastroenterology departments from several countries. Consecutive patients older than 45 years scheduled for upper endoscopy in each of these centers will be evaluated by High-Resolution- endoscopy with virtual chromoendoscopy and EGGIM will be calculated. Guided biopsies (if areas suspicious of IM) and/or random biopsies (if no areas suspicious of IM) in antrum and corpus will be made and OLGA/OLGIM stages calculated. Patients will be evaluated in clinical consultation and database will be fulfilled. All patients will be eradicated for Helicobacter pylori infection if positive. At that occasion, all the patients with EGGIM>5 and/or OLGA III/IV and/or OLGIM III/IV will be randomized for yearly (12 to 16 months) or every three years (32-40 months) endoscopic follow-up during a period of 6 years (SUPREME I). Endoscopic observational follow-up will be scheduled for patients with EGGIM 1-4 and OLGIM I/II at 3 and 6 years (SUPREME II). For individuals with no evidence of IM (EGGIM 0 and OLGIM 0, OLGA 0-II) a follow-up endoscopy 6 years after will be proposed (SUPREME III).
Patients with locally advanced gastric adenocarcinoma (cT2-4a N-/+ M0) were selected as study subjects to investigate the safety, efficacy, and feasibility of ICG near-infrared imaging tracing in guiding laparoscopic D2 lymph node dissection for gastric cancer after neoadjuvant chemotherapy by comparing injection ICG group and non-injection ICG group
The purpose of this study is to learn about the feasibility and safety of using Peptide Receptor Radionuclide Therapy (PRRT) before and after surgical removal of a tumor. PRRT treatment is based on the administration of a radioactive product, 177-Lu DOTA-0-Tyr3-Octreotate (Lutathera®) and its use before and after surgery is thought to increase the overall survival benefit for patients with SSTR-positive gastroenteropancreatic neuroendocrine tumors GEP-NETs.
This is a study of Camrelizumab (SHR-1210) and Apatinb for unresectable Recurrent or metastatic alpha-fetoprotein (AFP)-producing gastric cancer or Gastroesophageal Junction Adenocarcinoma. Camrelizumab combined with Apatinib and standard chemotherapy will be given to treatment-naïve participants; Camrelizumab combined with Apatinib will also be evaluated in participants who have had ≥ 1 line of previous treatment. The primary endpoint is the Overall Response Rate (ORR).
- If a patient undergoes gastrectomy, which is a kind of major abdominal operation, he/she loses more than 5% of his/her body weight in 2 months after surgery. This point is one of the criteria of 'risk of malnutrition' according to Nutrition Risk Screening (NRS 2002) and the patient who corresponds to this criterion needs nutritional support. - According to Nutrition Risk Screening (NRS 2002), moderate malnutrition is defined as the state that the patient orally intakes 25~50% of recommended requirements; severe malnutrition is less than 25%. - Meanwhile, when oral nutrition support was provided to patients after gastric cancer surgery, the patients' average daily intake during the first three months was about a half of the recommended requirements. - Putting together the facts i) that the patient underwent major abdominal operation, ii) that the weight loss rate exceeded 5% for two months, iii) that the average daily intake of patients during the first three months was about half of the recommended amount, the patients are eligible to be classified as a group who require nutritional support according to NRS 2002. Therefore, it is intended to verify the efficacy and safety of supplemental parenteral nutrition by comparing Arm A, who are provided oral intake with supplemental parenteral nutrition, Arm B, who are provided oral intake only after curative gastric cancer surgery.
This trial studies how well a prehabilitation program works to improve patient outcomes after surgery compared to the normal standard of care prehabilitation in frail patients undergoing surgery for pancreatic, liver, or gastric cancer. Frailty is defined as the pathophysiology of aging or through the accumulation of physiologic and functional deficits. Prehabilitation programs seek to optimize the medical and physical state of patients prior to undergoing surgery with the goal of improving outcomes following surgery. Despite evidence for its importance in health outcomes for frail patients, prehabilitation programs have not been well studied in cancer surgery populations. This trial may provide researchers with more information on how to improve patient outcomes after cancer surgery through the use of prehabilitation programs.
A retrospective, multi-center, single-blind, pivotal trial to assess clinical equivalence with stage II and III advanced gastric cancer based on the 6th and 8th of the AJCC
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.
