Active clinical trials for "Stomach Neoplasms"

This phase II trial studies the side effects and response of pulsed low dose rate radiation therapy in treating gastric cancer patients with peritoneal metastasis.

Gastric cancer is one of the major health problems worldwide, and one of the leading cause of death especially in Asia. Though the cytotoxic chemotherapy is the main treatment option, newer and molecularly targeted agents are recently incorporated to improve the survival outcome. Human epidermal growth factor receptor 2 (HER2, ErbB2) is a transmembrane tyrosine kinase receptor and is overexpressed or amplified in 10-20% of gastric cancer. Recently, Trastuzumab for Gastric Cancer (ToGA) study reported the clinical benefit of trastuzumab for HER2 positive gastric cancer patients. However, because the majority of patients develop intrinsic or acquired resistance within 1 year, elucidating the molecular mechanisms for trastuzumab resistance is warranted to improve the survival outcome of HER2 positive gastric cancer patients. A growing body of preclinical and clinical evidence shows that the immune system contributes substantially to the therapeutic effects of "monoclonal antibody, trastuzumab" in solid tumors. Pembrolizumab is a potent and highly selective humanized monoclonal antibody designed to directly block the interaction between PD-1 and its ligands, PD-L1 and PD-L2. Based on strong rationale in exploring the impact of combining trastuzumab with anti-PD-1 inhibitor in HER2 positive cancer, we suggest multicenter phase IB/II study to determine antitumor activity and safety of pembrolizumab in combination with standard treatment (trastuzumab, capecitabine, and cisplatin) in patients with HER2 positive gastric cancer.

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).

This is a randomized, open-label, multicenter phase III trial of ramucirumab plus paclitaxel, given as switch maintenance, versus continuation of first-line chemotherapy, given as per standard clinical practice, in subjects with unresectable locally advanced or metastatic HER-2 negative gastric or GEJ cancer, without disease progression following 3 months of first-line doublet chemotherapy. The acceptable first-line or lead-in chemotherapy will be: FOLFOX4:Oxaliplatin 85 mg/m2. l-Leucovorin 100 mg/m2 5-fluorouracil 400/600 mg/m2. Cycle length is 2 weeks +/- 3 days. ModifiedFOLFOX6: Oxaliplatin a 85 mg/m2. l-Leucovorin 200 mg/m2. 5-fluorouracil 400 mg/m2 and 2400 mg/m2 46-hours continous infusion. Cycle length is 2 weeks +/- 3 days. XELOX:Oxaliplatin130 mg/m2.Capecitabine will be 2000 mg/m2 for 14 days. Cycle length is 3 weeks +/- 3 days.

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.

Gastric cancer is one of the most common malignant tumors worldwide. With the rapid aging of global population, the number of elderly patients with local advanced gastric cancer is increasing. Surgery is the essential treatment for local advanced gastric cancer. However, because of the degeneration of physiological organs, cell functions, compensatory ability, immunity, and physiological reserve ability, elderly patients often face great safety issues when having surgery. Therefore, how to treat the elderly patients with local advanced gastric cancer with safe and effective surgery is one of the important problems in the field of gastric cancer treatment. With the introduction of minimally invasive treatment concepts and techniques, the role of laparoscopic radical gastrectomy in the treatment of early gastric cancer, as well as the advantages of trauma control and postoperative accelerated rehabilitation have been confirmed, however, there is still a lack of sufficient high-level clinical evidence in the elderly patients with advanced gastric cancer. The current study therefore aims to evaluate the safety and efficacy of laparoscopic versus open gastrectomy for advanced gastric cancer in elderly patients, using a randomized parallel controlled study design. The investigators hypothesized that laparoscopic gastrectomy is superior to open gastrectomy in terms of perioperative safety for local advanced gastric cancer patients aged 70 and above.

At present, apatinib was approved for the treatment of advanced gastric cancer after second-line or gastroesophageal junction adenocarcinoma, is in the second one, experience of medication, clinical data, no chemotherapy so now intends to carry out 40 cases of small sample exploratory research, in the conventional chemotherapy after the onset, with APA for Nigeria maintenance treatment, with a preliminary understanding of apatinib in first-line advanced gastric cancer to maintain the efficacy and safety of the treatment, and explore the feasibility of anti generate small molecule targeted therapy in advanced gastric cancer vascular pattern.
