Active clinical trials for "Stomach Neoplasms"

The purpose of this study is to determine the maximum tolerated dose and dose limiting toxicity of liposomal paclitaxel plus capecitabine in Chinese patients with advanced gastric carcinoma.

This is a randomized phase II multicenter controlled study of oxaliplatin, calcium folinate, and 5-fluorouracil (mFOLFOX7) as neoadjuvant chemotherapy for resectable advanced gastric cancer. Hypothesis: Neoadjuvant chemotherapy may improve 5 year overall survival compared with the control.

The purpose of this study is to compare the short- and long-term results between the laparoscopy-assisted gastrectomy and the open gastrectomy.

The goals of this study were to investigate whether two anesthesia regimens, with and without N2O, and bacterial colonization influence respiratory complications after major abdominal surgery for cancer.

In oncological aspect, D1+ lymph node dissection would be enough for early stage gastric cancer in advanced gastric cancer (stage IB/IIA/IIB ).

Surgical site infections (SSIs) is one of the most common complications of upper abdominal surgery. Previous studies found that type of surgical incision, emergency operation or not, surgical duration, age of patient, body mass index, malignance duration, malnutrition, complications (diabetes, shock, anemia et al) and drug (Long-term use of corticosteroids) are closely associated with the incidence of SSIs. The general incidence rate of SSIs was about 5% to 40%, although using the preoperative skin disinfectant and other methods to prevent and reduce the SSIs. And for the gastrointestinal surgery, due to the potential risk of infection, SSIs is an important problem which cannot be ignored. On the other hand, gastric cancer is one of the most common digestive system tumors, and gastrectomy is the primary therapeutic options. Therefore, it is important to compare the whether the different liquid (1% povidone-iodine solution or the 0.9% normal saline) wash the incision can influent the incidence of the SSIs.

The purpose of this study is to determine if reduced port totally laparoscopic distal gastrectomy with complete D2 lymph node dissection for gastric cancer is safe and oncological feasible. 67 patients with gastric cancer with preoperative staging from T1 to T3 will undergo reduced port totally laparoscopic distal gastrectomy. The primary end point of this study is to measure compliance rate with pathology report and compare with previous compliance rate data.

SinoFuan is a kind of Fluorouracil Implants for intraperitoneal chemotherapy during operation for treatment of gastric cancer. The indication has bee approved by Chinese FDA. The study is a post-marketing study. The subjects will be divided into two groups (Group A and Group B ). The subject in Group A will receive D2 radical gastrectomy(R0),Sinofuan during operation and 6 cycles of Xelox adjuvant chemotherapy.The subject in Group B will receive D2 radical gastrectomy(R0),and 6 cycles of Xelox adjuvant chemotherapy. The subject's benefits from SinoFuan will be analyzed through comparing 3 years DFS of two groups.

The incidence of cancer of the esophagogastric junction has rapidly risen in recent three decades, and surgery still remains the optimum therapy. For Siewert's type II and III cancer, esophagojejunostomy after total gastrectomy and Roux-en-Y gastrojejunostomy after subtotal gastrectomy are regarded as the two main surgical approaches. Esophagojejunostomy after total gastrectomy brings high survival rate and low local recurrence rate which may also induces pulmonary infection or regurgitation. Roux-en-Y gastrojejunostomy after subtotal gastrectomy needs reconstruction of the gastric tube and the width of reconstruction tube was a key factor to predicate prognosis. However, no evidence supplies a comprehensive standard on the width of reconstruction tube which often ranges from 3 cm to 6 cm. Both narrow and wide reconstruction tubes have their own advantages and disadvantages. So the prospective trail recruits patients into three groups: total gastrostomy group (TG group), wide gastric tube group (WG group) and narrow gastric tube group (NG group). And the investigators compare the quality of life using integrated questionnaire of QLQ-STO22 and QLQ-C30 and related symptom relief as main endpoints.

The purpose of this study is to conduct a study on genetic pathology, obtaining of pure cancer tissues is mandatory. Although the endoscopy with biopsy has been a gold standard for diagnosing gastric cancer, percentage of cancer cells in biopsy samples is usually 30% or less. Recently, confocal laser endomicroscopy has been introduced for real-time histopathologic diagnosis in various cancers. The investigators aim to evaluate that biopsy using probe-based confocal laser endomicroscopy will increase the percentage of cancer cells in biopsy samples.
