Active clinical trials for "Stomach Neoplasms"

The purpose of this study is to determine the maximum tolerated dose and dose limiting toxicity of liposomal paclitaxel plus capecitabine in Chinese patients with advanced gastric carcinoma.

This is a randomized phase II multicenter controlled study of oxaliplatin, calcium folinate, and 5-fluorouracil (mFOLFOX7) as neoadjuvant chemotherapy for resectable advanced gastric cancer. Hypothesis: Neoadjuvant chemotherapy may improve 5 year overall survival compared with the control.

The purpose of this study is to compare the short- and long-term results between the laparoscopy-assisted gastrectomy and the open gastrectomy.

Title: A single-center, retrospective randomized controlled trial of artificial intelligence (AI) versus expert endoscopists for diagnosis of gastric cancer in patients who underwent upper gastrointestinal endoscopy. Précis: this single-center, retrospective randomized controlled trial will include 500 outpatients who underwent upper gastrointestinal endoscopy for gastric cancer screening and will compare the diagnostic detection rate for gastric cancer of AI and expert endoscopists. Objectives Primary Objective: to evaluate the diagnostic detection rate for gastric cancer of AI and expert endoscopists. Secondary Objectives: to determine whether AI is not inferior to expert endoscopists in terms of the number of images analyzed for diagnosis of gastric cancer and intersection over union (IOU), and the detection rate of diagnosis of early and advanced gastric cancer. Endpoints Primary Endpoint: diagnosis of gastric cancer. Secondary Endpoints: image based diagnosis of gastric cancer and IOU. Population: in total, 500 males and females aged ≥ 20 years who underwent upper gastrointestinal endoscopy for screening of gastric cancer at a single hospital in Japan. Describe the Intervention: AI-based diagnosis of gastric cancer based on upper gastrointestinal endoscopy images. Study Duration: 3 months.

The goals of this study were to investigate whether two anesthesia regimens, with and without N2O, and bacterial colonization influence respiratory complications after major abdominal surgery for cancer.

The purpose of this study is to determine if reduced port totally laparoscopic distal gastrectomy with complete D2 lymph node dissection for gastric cancer is safe and oncological feasible. 67 patients with gastric cancer with preoperative staging from T1 to T3 will undergo reduced port totally laparoscopic distal gastrectomy. The primary end point of this study is to measure compliance rate with pathology report and compare with previous compliance rate data.

Surgical site infections (SSIs) is one of the most common complications of upper abdominal surgery. Previous studies found that type of surgical incision, emergency operation or not, surgical duration, age of patient, body mass index, malignance duration, malnutrition, complications (diabetes, shock, anemia et al) and drug (Long-term use of corticosteroids) are closely associated with the incidence of SSIs. The general incidence rate of SSIs was about 5% to 40%, although using the preoperative skin disinfectant and other methods to prevent and reduce the SSIs. And for the gastrointestinal surgery, due to the potential risk of infection, SSIs is an important problem which cannot be ignored. On the other hand, gastric cancer is one of the most common digestive system tumors, and gastrectomy is the primary therapeutic options. Therefore, it is important to compare the whether the different liquid (1% povidone-iodine solution or the 0.9% normal saline) wash the incision can influent the incidence of the SSIs.

In oncological aspect, D1+ lymph node dissection would be enough for early stage gastric cancer in advanced gastric cancer (stage IB/IIA/IIB ).

The purpose of this study is to conduct a study on genetic pathology, obtaining of pure cancer tissues is mandatory. Although the endoscopy with biopsy has been a gold standard for diagnosing gastric cancer, percentage of cancer cells in biopsy samples is usually 30% or less. Recently, confocal laser endomicroscopy has been introduced for real-time histopathologic diagnosis in various cancers. The investigators aim to evaluate that biopsy using probe-based confocal laser endomicroscopy will increase the percentage of cancer cells in biopsy samples.

SinoFuan is a kind of Fluorouracil Implants for intraperitoneal chemotherapy during operation for treatment of gastric cancer. The indication has bee approved by Chinese FDA. The study is a post-marketing study. The subjects will be divided into two groups (Group A and Group B ). The subject in Group A will receive D2 radical gastrectomy(R0),Sinofuan during operation and 6 cycles of Xelox adjuvant chemotherapy.The subject in Group B will receive D2 radical gastrectomy(R0),and 6 cycles of Xelox adjuvant chemotherapy. The subject's benefits from SinoFuan will be analyzed through comparing 3 years DFS of two groups.
