Active clinical trials for "Stomach Neoplasms"

The purpose of this study is to determine whether positive lifestyle interventions (diet modification and smoking cessation) are effective in the prevention of gastric pre-cancer and cancer occurrences and reccurence of gastric cancer after endoscopic resection.

Gastric cancer patients after total gastrectomy will be randomized to oral nutritional supplement group or control group at discharge. Patients will receive 6 months of oral nutritional supplement or normal diet after discharge. The primary and secondary outcomes will be collected.

Cachexia is a common complication of various advanced malignant tumors, which seriously affects the quality of life and survival time of patients. In view of the clinical problem of non-nutritional response in patients with cachexia, the investigators plan to carry out a clinical case-control study on the intervention of creatine combined with curcumin in participants with cachexia. On the whole, the investigators limited the study subjects to upper digestive tract tumors and diagnosed participants with early cachexia. The main purpose of this study is to determine whether the combination of the two can play a positive and stable role in inhibiting the inflammation of cachexia and improving metabolic status, so that basic nutrition can play a role, in order to reduce the level of skeletal muscle consumption, maintain weight, improve quality of life, save medical costs and extend survival time.

Recently, laparoscopic gastrectomy has been gradually accepted by surgeons worldwide for gastric cancer treatment. Complete dissection of the lymph nodes and the establishment of the surgical margin are the most important considerations for curative gastric cancer surgery. Previous studies have demonstrated that indocyanine green (ICG)-traced laparoscopic gastrectomy significantly improves the completeness of lymph node dissection. However, it remains difficult to identify the tumor location intraoperatively for gastric cancers that are staged ≤T3. Here, the investigatorsinvestigated the feasibility of ICG fluorescence for lymph node mapping and tumor localization during totally laparoscopic distal gastrectomy.Preoperative and perioperative data from consecutive patients with gastric cancer who underwent a laparoscopic proximal gastrectomy were collected and analyzed. The investigators want to know if near-infrared fluorescence imaging with ICG can be successfully used in laparoscopic proximal gastrectomy, and if it contributes to both the completeness of D2 lymph node dissection and confirmation of the gastric transection line. The application of ICG labeled near infrared imaging fluorescence laparoscopic technology is still in the stage of exploration and experience accumulation, and it needs to be comprehensively evaluated through a large number of prospective randomized controlled studies.

This study aims to explore the value of indocyanine green (ICG) in laparoscopic distal gastrectomy with lymph node dissection for early gastric cancer.The patients with early gastric adenocarcinoma (cT1, N-/+, M0) will be studied.

European clinical guidelines do not establish a clear recommendation neither for nor against omentectomy of this segment, the American clinical guidelines recommend omentectomy in view of its potential long-term oncological benefit, and Japanese clinical guidelines only recommend 2nd segment omentectomy in locally advanced gastric cancers (stage T3-T4) recommending omental preservation in early gastric cancers (stage T1-T2). Faced with this lack of consensus, we propose a randomized, prospective and multicentric study in patients with resectable gastric cancer in stage T3-4 N+/- M0. Patients will be randomized into two groups, one where omentectomy of the 2nd omental portion will be performed and another where omental preservation will be performed. The aim of our study is to analyze the disease-free interval and survival between both groups, also comparing postoperative complications and mortality.

SENORITA 1 trial showed laparoscopic sentinel lymph node biopsy and stomach preserving surgery in early gastric cancer can increase the quality of life. (Ryu KW et al. JCO 2022) The radioactive isotope is difficult to use because of the hazard of radiation and shortage of materials. The aim of this study is to investigate whether laparoscopic sentinel lymph node biopsy and stomach-preserving surgery using only fluorescence is feasible.

This randomized study examines how well zinc works in improving quality of life in patients with gastrointestinal cancer that cannot be removed by surgery who are receiving chemotherapy. Zinc may help to improve patient's quality of life by preventing zinc deficiency.

Recently, the use of mobile health is increasing for the purpose of managing prognosis such as recurrence, survival and quality of life by using a wearable smart band together with a smartphone application. In the era of the 4th revolution, mobile health for the purpose of comprehensive prognosis for cancer patients is becoming a very good tool. As a result of applying a mobile application for health management (nutrition, health education, exercise, etc.) to 203 gastric cancer or colon cancer patients undergoing chemotherapy in the previous study, gastric cancer patients are most interested in health-related education and information. As such, it was possible to confirm the clinical significance of short-term and temporary health care through mobile applications and smart bands during the treatment process for gastric cancer patients, but the study was insufficient to generalize the number of subjects. Therefore, until now, the results of a multicenter randomized-control study have not been found after long-term application as a supportive tool from immediately after surgery (before treatment) to during the treatment process. Therefore, in gastric cancer patients who need prognosis management after surgery, we will investigate the effect of mobile application with smart band which has a modular structure reflecting the treatment method and treatment process after surgery. This study targets patients who underwent gastric cancer surgery, an intervention group (App+IoT device) uses a smart care application tailored to gastric cancer patients created by reflecting the treatment process immediately after surgery and a wearable smart band for 12 months. Control group was provided general education through the hospital brochure. Evaluation will be conducted 2-3days after surgery (before discharge), and at 1, 3, 6, and 12 months after surgery.

This clinical trial test whether taking part in a diet support intervention will help with patients nutrition and quality of life after surgery for esophagus or stomach cancer. The information learned by doing this research study may help patients get more information and/or support on eating after esophagus and stomach cancer surgery.
