NCT ID: NCT04510285 Terminated - Gastric Cancer Clinical Trials

A Single-Arm Pilot Study of Adjuvant Pembrolizumab Plus Trastuzumab in HER2+ Esophagogastric Tumors With Persistent Circulating Tumor DNA Following Curative Resection

Start date: August 10, 2020
Phase: Phase 2
Study type: Interventional

The purpose of this study is to find out whether treatment with trastuzumab combined with pembrolizumab will improve the clearance of tumor DNA from participants' bodies after surgery.

NCT ID: NCT02161029 Completed - Gastric Tumor Clinical Trials

Flexible Endoscopy Biopsies for Submucous Tumors With a New Drill Instrument

Start date: July 2, 2014
Phase: N/A
Study type: Interventional

The purpose of this study is to determine whether the newly constructed CE (Conformité Européenne) marked drill biopsy instrument for flexible endoscopes can make possible representative biopsies of the increasing numbers of submucosal tumours in the gastrointestinal tract. The amount of submucous tissue ( micrograms and in % of all the biopsy) harvested with the new drill biopsy instrument used in flexible endoscopy investigations is measured in the study and compared to the amount of submucous tissue harvested with the existing biopsy forceps.

NCT ID: NCT01832246 Not yet recruiting - Clinical trials for Early Gastric Cancer

Endoscopic Ultrasonographic Staging and Conventional Endoscopic Staging for Depth of Invasion for Early Gastric Cancer

Start date: December 2014
Phase: N/A
Study type: Observational

The accurate prediction of depth of tumor invasion in early gastric cancer is essential for the proper selection of candidates for endoscopic resection. Conventional endoscopy and endoscopic ultrasonography have been useful diagnostic method for depth of invasion in early gastric cancer. However, there has been no prospective comparative study on the accuracy between the 2 methods. Therefore, the investigators prospectively compare the accuracy between the 2 methods regarding prediction of depth of invasion.

NCT ID: NCT01819961 Not yet recruiting - Liver Tumor Clinical Trials

Parenteral Fish Oil in Major Laparoscopic Abdominal Surgery

Start date: April 2013
Phase: Phase 4
Study type: Interventional

The aim of this study is to assess the effect of postoperative parenteral fish oil on clinical outcome and immune function after major laparoscopic abdominal surgery.

NCT ID: NCT01698190 Recruiting - Lymphadenopathy Clinical Trials

Comparing the Efficacy of Endoscopic FNA vs FNB in Diagnosing Solid Gastrointestinal Lesions

Start date: December 2011
Phase: N/A
Study type: Interventional

The purpose of this study is to determine if fine needle aspiration or fine needle biopsy is more efficacious and cost-effective than the other while maintaining diagnostic accuracy in the setting of solid gastrointestinal lesions.

NCT ID: NCT01697943 Recruiting - Gastric Tumor Clinical Trials

Impact of Roux-En-Y Pouch Reconstruction Compared With Conventional Roux-En-Y Reconstruction on Quality of Life in Patients Undergoing Total Gastrectomy

GCQOL02
Start date: May 2012
Phase: Phase 3
Study type: Interventional

The purpose of this study is to find out more about differences of the quality of life in patients undergoing Roux-En-Y pouch reconstruction and conventional Roux-En-Y reconstruction. To find a better reconstruction for patients who received total gastrectomy.

NCT ID: NCT01579071 Completed - Gastric Tumor Clinical Trials

Efficacy and Safety of CO2 vs Room Air Insufflation During ESD for Gastric Tumor

Start date: April 2012
Phase: Phase 4
Study type: Interventional

Insufflation is essential procedure to observe the lumen of gastrointestinal tract in gastroscopy or colonoscopy Currently, most of hospital in Korea are using room air for insufflation According to recent clinical studies have shown that carbon dioxide have better safe and reduce stomachache than room air when endoscopy and endoscopic procedure is performed. However, there was still no research data or study in Korea. In this study, the investigators will try to make comparison between Carbon dioxide and room air insufflation for endoscopic submucosal dissection for Gastric Tumor and investigate the efficacy and safety

NCT ID: NCT01510730 Completed - Helicobacter Pylori Clinical Trials

Helicobacter Pylori Eradication After Endoscopic Resection of Gastric Tumors

Start date: January 2005
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine whether Helicobacter pylori eradication could reduce the new tumor development after endoscopic resection of gastric tumor.
