Active clinical trials for "Stomach Neoplasms"

The purpose of this study is to evaluate the oncological feasibility of laparoscopy-assisted distal gastrectomy with D2 lymph node dissection for advanced gastric cancer.

Advanced gastric cancer combined with peritoneal seeind has dismal prognosis with poor response to systemic chemotherapy and with rapid aggravation of symptoms such as abdominal pain, ileus, and poor nutritional intake. Intraperitoneal (IP) chemotherapy through IP port or catheter has lower complication than HIPEC (hyperthermic intraperitoneal chemotherapy) and can deliver higher dose of chemotherapy with less systemic toxicity. IP chemotherapy combined with systemic chemotehrapy showed benefit in several clinical trials, despite lack of statistical significance in phase 3 clinical trial. Proper dose/combination of chemotherapeutic agents and indication of IP chemotherapy should be investigated through prospective, large-scale clinical trials. Conversion surgery after cytotoxic chemotherapy showed improved survival in retrospective studies. Our hypothesis is that IP chemotherapy combined with systemic chemotherpay (capecitabine + oxaliplatin) would improve success rate of conversion surgery with R0 resection. In the present study, the treatment regimen consists of intraperitoneal paclitaxel combined with oxaliplatin and capecitabine (XELOX), and will be performed following surgery.

Nefopam will be administered to the patients undergoing laparoscopic gastrectomy under the total intravenous anesthesia (TIVA). The investigators will evaluate whether the nefopam can decrease the total amount of remifentanil administered during the operation, which will reduce the acute opioid tolerance and following consumption of fentanyl during postoperative period.

The purpose of this study is to investigate the maximum tolerated dose and pharmacokinetics of liposomal paclitaxel with/without capecitabine in Chinese cancer patients with advanced gastric carcinoma.

The Advantages and Disadvantages Between Uncut Roux-en-Y Reconstruction and Billroth II Reconstruction After Laparoscopy-assisted Distal Gastrectomy for Gastric.

Many features of the metabolic syndrome are associated with insulin resistance. And, metabolic syndrome and insulin resistance are related to visceral obesity. Therefore, the investigators hypothesized that visceral fat removal (omentectomy) can make favorable results for the insulin resistance and metabolic syndrome. As the omentectomy is optional procedure during a surgery for early gastric cancer, the investigators will divide patients randomly into two groups, total omentectomy group and omentum preserving group.

Gastroenterologists often follow up second look endoscopy after endoscopic submucosal dissection(ESD) of gastric neoplasms because they want to prevent bleeding of procedure sites. But Goto suggested in his retrospective analysis that a second-look endoscopy after endoscopic submucosal dissection for gastric epithelial neoplasm may be unnecessary. So, the investigators try to identify the hypothesis prospectively in this study.

This study aim to assess quality of life of patients 0-5 years after oesophageal or gastric cancer surgery and to develop and test an information and support program aiming to enhance the patients quality of life (QOL) after surgery. The project contains 3 part-studies focusing on the patients life after surgery. Data will be collected through focus group interviews and a randomized controlled trial (RCT) study.

The aim of the study is to evaluate whether subtotal gastrectomy without post-operative nasogastric decompression is better in terms of early post-operative bowel function and chest complication.
