Active clinical trials for "Stomach Neoplasms"

Gastric cancer is the second cause of cancer related death and China has the most gastric cancer patients in the world. Although systemic strategies, including adjuvant chemotherapy, postoperative chemoradiotherapy, perioperative chemotherapy, have evolved and showed benefits these years, the prognosis of advanced gastric cancer is still not satisfactory. Optimal regimens and optimal method administration is still being found. Neoadjuvant chemotherapy has many advantages, including downstaging the tumor, increasing R0 rate, early eradicating of micrometastasis. In previous trials, combination of paclitaxel and s-1 has showed safety and tolerance in recurrent or metastatic gastric cancer. Using liposome as a carrier, paclitaxel has a better histocompatibility and cellular affinity, resulting a improved stability and reduced toxicity. In this phase II trial, we are going to study the safety and feasibility of paclitaxel liposome plus s-1 as neoadjuvant chemotherapy.

The purpose of this study is to determine efficacy of SB injection in Gastric Cancer.

The purpose of this study is to determine whether sequential chemotherapy with capecitabine plus oxaliplatin (Xelox) followed by docetaxel plus capecitabine (TX)in unresectable gastric cancer.

Cisplatin, an intravenously administered platinum agent, in combination with an intravenously administered taxane and capecitabine has been shown to improve time to disease progression and overall survival in previously untreated patients with gastric cancer. This study is being performed to evaluate an orally administered taxane (tesetaxel) in combination with cisplatin and capecitabine in previously untreated patients with gastric cancer.

This is a single arm phase 2 trial evaluating the efficacy and tolerability of intraperitoneal paclitaxel with oxaliplatin and capecitabine in advanced gastric cancer patients with peritoneal metastasis and/or cancer cells on peritoneal cytology. Twenty patients will be recruited into the study for an estimated period of two years. Paclitaxel will be administered intraperitoneally at 40mg/m2 on Day 1 and 8 in patients receiving standard intravenous oxaliplatin 130mg/m2 on Day 1 and capecitabine 1000mg/m2 on day 1-14. The study hypothesizes that the addition of intraperitoneal paclitaxel with chemotherapy will improve treatment efficacy.

Stage 1:First line therapy Sequential therapy of S1+Docetaxel followed by S1 is superior to concomitant S1+Docetaxel in the safety and clinical efficiency. Stage 2:Second line therapy To explore the feasibility of single drug(S1) maintenance treatment for advanced gastric cancer.

The class of proton pump inhibitor (PPI) medications such as omeprazole has proven extremely effective in the treatment and prevention of gastric and duodenal ulcers. Although the FDA approval for PPI therapy is limited to 6-8 weeks, many individuals remain on these agents for years, and human studies have suggested that long-term use of a PPI can result in enterochromaffin-like (ECL) cell hyperplasia, as well as being associated with the development of fundic-gland polyps of the stomach. These findings raise the concern of the possibility that long-term use of PPIs may predispose to the development of neuroendocrine tumors in patients. The investigators aim to examine clinical parameters, including history of PPI use and fasting gastrin levels, as well as histologic characteristics (particularly the presence of ECL-cell hyperplasia) of patients found to have fundic gland polyps during endoscopy. The investigators hypothesize that there is a correlation between fundic gland polyps of the stomach and the use of proton pump inhibiter medications.

The aim of this study is to elucidate the efficacy and safety of XP and SP for first-line treatment of Advanced Gastric Cancer.

The purpose of this study is to assess the safety and efficacy of S-1 plus oxaliplatin combination chemotherapy based on the adverse events and survival period by performing a phase I/II study of this combination in patients with D2 resection of gastric cancer.

Intraperitoneal chemotherapy as an adjuvant treatment modality is designed to eradicate intraperitoneal free tumor cells that can be a source of peritoneal carcinomatosis. Although we have not reached unanimous consensus, favorable reports on the outcome of intraperitoneal chemotherapy have been published. In this study, we review the clinicopathological characteristics of patients and effects of early postoperative intraperitoneal chemotherapy (EPIC) on overall and gastric cancer-specific survival and patterns of recurrence of gastric cancer patients with macroscopic serosal invasion. The aim of this study is to evaluate the impact of intraperitoneal chemotherapy on overall and disease free survival of advanced gastric cancer patients with serosal invasion after potentially curative surgery.
