Active clinical trials for "Stomach Neoplasms"

The purpose of this study is to evaluate the effect and safety of laparoscopy-assisted D2 radical surgery for distal advanced gastric cancer.

The purpose of this study is to compare the effects and safety of Anlotinib with placebo in patients with Gastric Cancer.

The purpose of this study is to determine whether raltitrexed concurrent with IMRT is safe, tolerable and effective in the treatment for patients with local-advanced gastric cancer after D0/D1 radical resection.

Using random case assignment to investigate the analgesic and sedative effect of intravenous dexmedetomidine and dexmedetomidine as a local anesthetic adjuvant in ultrasound-guided subcostal TAP block in gastric cancer patient undergoing gastrectomy or partial gastrectomy.

This study evaluate the safety and tolerance of MASCT-I(multiple-antigen specific cell therapy) combined with PD1 antibody in patients with advanced gastric cancer who failed in first-line chemotherapy. The study is divided into three stages: the first, second stage is the stage of the dose climbing, and the third stage is the dose expansion stage. The patients would be treated with MASCT-I single drug therapy, MASCT-I+ low dose PD1 antibody therapy, and MASCT-I+ high dose PD1 antibody therapy.

Evaluate the feasibility ,safety and efficacy of Surgery，Chemotherapy in Combination with Autologous T cells-Based Immunotherapy for Advanced Gastric Cancer.

This is an open label, multi-center, and randomized phase II trial designed to compare the safety and efficacy of direct oral anticoagulants and subcutaneous dalteparin in patients with acute venous thromboembolism and upper gastrointestinal, hepatobiliary, or pancreatic cancer, based on a group sequential design. Enrolled patients will be randomized in a 1:1 ratio. Patients will be stratified by performance status, type of cancer, chemotherapy and medical centers.

To assess the primary effects and safety of Anlotinib in patients with Gastroenteropancreatic Neuroendocrine Tumor G3.

This study aims to evaluate safety and efficacy of nivolumab (anti-PD-1 antibody), which is approved as tertiary therapy, and neoadjuvant short-term limited local radiotherapy in patients with unresectable recurrent gastric cancer who progressed (intolerance or PD) after standard treatment (primary and secondary chemotherapy) and have more than one lesion assessable in diagnostic imaging (one lesion must be >=2cm).

RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, S-1, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. It is not yet known whether giving oxaliplatin together with S-1 is more effective than giving oxaliplatin together with capecitabine. PURPOSE: This randomized phase II trial is studying how well giving oxaliplatin together with S-1 works compared to oxaliplatin given together with capecitabine in treating patients with recurrent, metastatic, or unresectable gastric cancer.
