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.

Splenic hilum remains challenging during total gastrectomy with D2 lymphadenectomy.The application of minimally invasive surgery for advanced gastric cancer is gaining popularity. The investigators aim to compare the safety and feasibility of LTG and OTG for advanced proximal gastric cancer.

The investigators intend to conduct a randomized controlled study to find if combining HIPEC (hyperthermic intraperitoneal perfusion chemotherapy) with post-neoadjuvant chemotherapy D2 resection could improve survival for patients with advanced gastric cancer, while comparing with the traditional approach of D2 resection after neoadjuvant chemotherapy.

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.

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.

This is an open-label, Phase 1b study which will be conducted in two parts: part A is the dose escalation study while part B is dose expansion study. The purpose of the dose escalation part is to identify the maximum tolerated dose (MTD) and/or recommended phase II dose (RP2D) of CM082 combined with paclitaxel in patients with advanced gastric cancer who did not respond to first-line standard chemotherapy. In the subsequent dose expansion part, additional subjects will be enrolled to further explore the safety and preliminary clinical activity of CM082 and paclitaxel.

The purpose of this study is to explore the clinical outcomes of laparoscopic D1 lymphadenectomy for elderly patients with advanced gastric adenocarcinoma（cT2-4a, N-/+, M0）

Prospective observational trial. A full thickness resection of gastric subepithelial tumors is performed after application of full thickness sutures underneath the tumor with the GERDX(TM) device. Hypothesis: This endoscopic method is feasible, effective and safe.
