Active clinical trials for "Stomach Neoplasms"

Gastric cancer is one of the most common malignant tumors of the digestive tract. Gastric cancer patients diagnosed for the first time in China have a higher proportion of advanced stages and a higher postoperative metastasis rate.Studies have shown that patients with good pathological response after preoperative neoadjuvant therapy (such as tumor regression grade, TRG0 or 1) have a better prognosis.The purpose of this study is to treat patients with advanced gastric cancer who are difficult to perform R0 surgery with chemotherapy combined with immunotherapy. At the same time as the primary cancerous lesions are reduced, the distant metastatic lesions are effectively controlled in order to perform R0 surgery and to improve the survival rate of patients with advanced gastric cancer.

This study is a phase II study, to evaluate the effectiveness and safety of Camrelizumab combined with apatinib for advanced gastric or esophagogastric adenocarcinoma progressed after immune checkpoint inhibitors.

In this study, patients with advanced gastric adenocarcinoma whose peritoneal metastasis and peritoneal nodule pathologically confirmed metastasis and/or exfoliative cytology were confirmed as the clinical stage of peritoneal metastasis, who had not received treatment before, were invited to participate in the study.To evaluate the surgical conversion rate and tumor regression grade (TRG grade) of patients with stage gastric cancer with peritoneal metastasis using docetaxel, oxaliplatin, fluorouracil (FLOT regimen) combined with teriprizumab (PD-1).

This study is to evaluate the efficacy and safety of domestic programmed death 1（ PD-1） antibody (Camrelizumab for injection) combined with fluorouracil plus leucovorin, oxaliplatin, and albumin bound paclitaxel (modified FLOT, mFLOT) regimen in the treatment of patients with unresectable locally advanced or limited metastatic gastric cancer. The primary efficacy endpoint is R0 resection rate.

The investigators assessed whether the addition of a preoperative regimen of Bevacizumab regimen to improves R0 resection rate and survival among patients with potentially resectable gastric cancer with liver metastasis.

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

To confirm the efficacy and safety of XELOX with capecitabine maintenance in treatment of advanced gastric cancer (AGC)

Safety and Efficacy of Ginsenoside Rg3 in Combination with First-line Chemotherapy in Advanced Gastric Cancer.The purpose of this study is to assess the safety of Ginsenoside Rg3 in advanced gastric cancer, and whether it improves the efficacy of first-line chemotherapy.

Gastric cancer remains a major health issue and a leading cause of cancer death worldwide, although the prevalence and mortality of the disease have gradually decreased. The investigators have very few options for patients with advanced disease. The trastuzumab for Gastric Cancer (ToGA) trial, a pivotal randomized clinical trial of patients with HER-2 positive advanced, mostly metastatic, gastric cancer, proved the efficacy of trastuzumab (anti-Her 2 therapy) in combination with chemotherapy. The median overall survival was significantly prolonged in the trastuzumab-containing arm (13.8 vs. 11.1 months; HR 0.74; p=0.0046) without unexpected toxicity including cardiac events. The survival benefit was most pronounced in the subgroup of high HER-2/neu protein overexpression (median overall survival of 16 months). Only 20% of the patients screened and subsequently enrolled for this study were found to be HER2-positive when utilizing both immunohistochemistry and FISH. Her2 testing is recommended for all patients with advanced gastric cancers and type III oesophageal adenocarcinomas. Data on Indian patients is lacking. Hence, the investigators plan to test for Her 2 in 100 patients with IHC and FISH in 2+ and 3+ patients.

Gastric bypass improves glycemic levels in type 2 diabetes. However, the efficacy may be varied by different gastric-small intestine reconstruction used in the procedure. There are reports that Roux en Y reconstruction may give a better result. The purpose of this study is to compare Roux en Y and Billroth II reconstruction in patients with gastric cancer comorbid with type 2 diabetes.
