Filter by:As the number of obesity continues to increase, surgical oncologist pay more attention to the effect of obesity on surgical outcomes and survival of digestive systemin cancers. Body mass index(BMI) is one of the most widely used measurements of obesity. Abdominal fat area (AFA) calculated by computed tomography is popular because of its validity of fat distribution. There is still no consensus which of BMI and AFA could be the more effective measurement and more accurate to evaluate effect of obesity on surgical outcomes and survival. Gastric cancer is one of the most common digestive system cancers, and gastrectomy is the primary therapeutic options.It is important to compare the different measurements(BMI or AFA) to assess obesity and effect on surgical outcome and survival for gastric cancer patients.
The purpose of this study is to identify patients at risk for future heart failure using novel markers of early cardiac damage and determine if exercise training can improve these emerging markers as well as overall fitness and quality of life.
A clinical study of the efficacy of oral alpha-difluoromethylornithine (eflornithine or DFMO) in male and female subjects ages 30-60 with gastric premalignant lesions in two high risk regions of Latin America.
The aim of surgical procedures for resection of cancer stomach is to resection of the tumor mass with safety margin and its drainage lymph nodes (lymphadenectomy). There are two main types of techniques (open & laparoscopic) Many studies were done comparing these two techniques showed that Laparoscopic resection is superior in early postoperative recovery (less pain ,less bleeding and shorter hospital stay) but less radical than open resection (less safety margin & less lymphadenectomy) but because of the ongoing advances on laparoscopic surgery these results needs more and more revision. So the investigators conduct this randomized controlled trial aiming at comparing open and laparoscopic resection of cancer stomach to choose the best surgical procedure for resection of cancer stomach.
Helicobacter pylori is a common bacterial infection. It can lead to severe stomach problems, including stomach cancer. Researchers want to look at samples of the bacteria. These H. pylori strains will be taken from chronically infected people. They want to identify the genetic and epigenetic differences in H. pylori strains. This could help predict which people who get infected with the bacteria will get stomach cancer. This could lead to the cancer being detected earlier. It could also mean less people get stomach cancer. Objectives: To study genetic variations of H. pylori strains based on samples from chronically infected people. To identify the features of strains that might lead to severe stomach problems or stomach cancer. Eligibility: People ages 30-70 years who need an upper endoscopy or who were recently diagnosed with stomach cancer Design: Participants will be screened by the doctor who does their procedure and a study nurse. Participants who have endoscopy will have ~6 biopsies removed. These are tissue samples. They are about the size of a grain of rice. Participants will allow the study team to access reports from their stomach exam. Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care. They will allow the study team to access reports of their surgery. They will also allow them to access the microscope slides of their stomach.
Selection of the optimal treatment for gastric outlet obstruction in patients with radically unresectable gastric cancer remains controversial because previous studies comparing the two procedures had a small sample size as well as they included various etiologies such as gastrointestinal (GI) cancer, duodenal cancer and pancreaticobiliary cancer in selecting the patient population. Therefore, to establish the standard of care for patients with radically unresectable gastric cancer with gastric outlet obstruction, a larger prospective, randomized, controlled clinical trial using a single type of stent is warranted.
Perioperative chemotherapy is the gold standard treatment in the resectable and advanced gastroesophageal adenocarcinoma. The efficacy of this strategy has been demonstrated in two randomized studies (1,2). It reduces tumour size before surgery, treats micrometastases and evaluates chemosensitivity. Disease free and overall survival rates were significantly improved with perioperative chemotherapy compared to surgery alone. However, the limitation of these studies is that among all patients requiring chemotherapy, almost 70% of patients will not have the complete sequence. This sequence is defined by the administration of 2 to 4 cycles before and 2 to 4 cycles after the surgery, according to the protocol. The major cause of absence or impossibility of realization of postoperative chemotherapy was the presence of postoperative complication, postoperative serious asthenia and impaired nutritional and physical status (1,2). Poor physical condition assessed by cardiopulmonary exercise testing, reflecting a reduced physiological reserve, is predictive of postoperative complications (3,4). A physical training, even during a short period and on a various population, is beneficial in improving physical condition, cardiopulmonary function and muscular mass of the patient (5-8). A prehabilitation over a 6 week period between surgical consultation and surgery decreases postoperative morbidity and the hospital stay in cardiovascular surgery but no study has ever been performed in the gastric or oesophageal cancer (7,9). Prehabilitation revolves around three axes: 1) a physical training based on initial cardiopulmonary exercise testing (VO2peak, anaerobic threshold (AT) and 6-min walk test (6MWT)), 3 times by week, supervised by a physical therapist 2) a nutritional care to ensure the compliance of the nutrition program and adapt the nutritional management based on protein and energy needs and on the level of spontaneous oral intake and 2) a psychological treatment by a psychologist to reduce preoperative anxiety. To our knowledge, no study ever focused on the gastroesophageal cancer. The benefit of prehabilitation in this cancer may be particularly important because 1) this surgery is associated with a high postoperative morbidity (40%, especially respiratory) and mortality (5%) 2) the physical and nutritional status of these patients is often precarious (cancer cachexia, gastroesophageal obstruction), and 3) the need to preoperative chemotherapy declines physical reserves and is associated with a lengthening of the time between consultation and surgery of more than 3 months (10). Also, the investigators hypothesize that with a physical training, a personalized nutritional support and a psychologist management may decrease postoperative complications, increase postoperative nutritional status and so, would allow for more patients to receive their full cancer treatment. The aim of this study was to evaluate, in gastroesophageal adenocarcinoma, the effect of prehabilitation compared to conventional care, the percentage of patients reaching the complete oncological treatment decided in a multidisciplinary tumour board.
The main purpose of this study is to evaluate whether the Apatinib can improve the disease free survival (DFS) of gastric cancer patients in stage IIIB/IIIc, who had completed postoprative adjuvant chemotherapy. Meanwhile, the investigators also will evaluate whether the Apatinib can improve the overall survival (OS), estimate the quality of life of patients have taken the Apatinib and monitor the security of Apatinib.
Apatinib dose titration in Advanced or Metastatic Gastric Cancer
Background. Gastric cancer surgery is associated with high risk for postoperative morbidity and mortality. Anastomotic leak (AL) is one of the worst complications associated with relevant short and long-term sequelae. Procalcitonin (PCT) is a biomarker used to monitor bacterial infections and guide antibiotic therapy and has been shown to have better predictive value of AL after colorectal surgery than C-reactive protein (CRP) and white blood cell count (WBC). Purpose. Investigators designed a monocentric pilot study to test if PCT might be a sensitive and reliable marker of AL after gastric surgery
