NCT ID: NCT03486574 Completed - Gastric Cancer Clinical Trials

Research for Associated Genes for Gastric Cancer in Family Member With Affected First-Degree Relatives

Start date: December 7, 2016
Phase:
Study type: Observational

Familial gastric cancer accounts for 10% of all cases, but predisposing genetic variations is unknown except for CDH1 mutation. Because Germline mutation is believed to be a key aspect of cancer predisposition, we plan to recruit persons with 2 or more affected family members in three-generation pedigree. The investigators will perform a whole-exome sequencing using DNA from blood samples of families including gastric cancer patients and non-gastric cancer patients

NCT ID: NCT03486379 Completed - Gastric Cancer Clinical Trials

Start date: April 2, 2018
Phase: Phase 2
Study type: Interventional

GlobalSurg 3: Quality and Outcomes in Global Cancer Surgery

GS3
Start date: April 1, 2018
Phase:
Study type: Observational

Aim The aim is to determine the variation in quality of cancer surgery worldwide. Quality will be determined using measures covering infrastructure, care processes, and outcomes. The study will concentrate on the most common surgically treated cancers worldwide: breast, gastric and colorectal cancer. The primary aim focusses on 30-day mortality and complication rates after cancer surgery. The secondary aim is to characterise infrastructure and care processes in the treatment of these cancers worldwide. Primary outcome measure 30-day mortality and complication rates after cancer surgery. Primary comparison Between country groups defined by human development index. Hospital eligibility Any hospital in the world performing surgery for breast, gastric or colorectal cancer. Patient eligibility Consecutive patients undergoing surgery for breast, gastric, or colorectal cancer. Surgery can be with palliative or curative intent. Team Individual hospital teams with up to three people, collecting data for four weeks. Several teams collecting data over multiple four-week periods is encouraged. Time period Patients will be identified, and data collected on all patients during the time-period with follow-up to 30-days. The study will run from 1st April 2018 to 31st October 2018 (with follow-up of the last period to 30th November 2018). Validation Data validation will be in two parts. First, centres will self-report the key processes used to identify and follow-up patients. Second, independent validators will quantitatively report case ascertainment and sampled data accuracy.

NCT ID: NCT03430778 Completed - Gastric Cancer Clinical Trials

Effect of Pneumoperitoneum on the Continuous and Non-invasive Hemoglobin Monitoring

Start date: January 1, 2019
Phase: N/A
Study type: Interventional

The primary purpose of this study is to investigate the effect of pneumoperitoneum on the continuous and non-invasive hemoglobin monitoring during laparoscopic gastrectomy

NCT ID: NCT03425058 Completed - Gastric Cancer Clinical Trials

Molecular Evaluation of Neoadjuvant Chemotherapy for Locally Advanced Gastric Cancer

MENCA-GC
Start date: November 22, 2017
Phase:
Study type: Observational

Gastric cancer (GC) is a leading global health problem and is the third most common cause of cancer related death. Neoadjuvant chemoradiotherapy (nCRT) followed by surgery is the mainstay treatment for locally advanced gastric cancer, and variable degrees of tumor regression are observed after nCRT. Treatment strategies, including close surveillance without immediate surgery, have been investigated to spare patients with complete tumor regression from potentially adverse outcomes of radical surgery. However, clinical and radiological assessment of treatment response does not deliver an ideal accuracy of patients identification with complete response. In the present study, we focused on the clinical courses of patients who have developed locally advanced gastric cancer, and investigated the potential clinical utility of the detection of deficient MMR(dMMR), microsatellite instability(MSI) status and the decreasing level of circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) as promising biomarkers for the diagnosis and prediction of GC during treatment progress. Twenty milliliters of plasma were collected at 3 time points: before nCRT; after 2 cycles of nCRT; and after surgery. Firefly ctDNA NGS assays were used to track ctDNA mutations previously characterized in paired tumor tissue by massively parallel sequencing (MPS). We investigated whether circulating tumor DNA (ctDNA) detection can reflect tumor response to nCRT and detect minimal residual disease(MRD) after surgery. We compared CTC and ctDNA levels to clinical, radiological and pathological assessment modalities for nCRT response. The results will provide lots of information which may contribute to promote the treatment of GC patients. We want to introduce these strategies into clinical practice if possible.

NCT ID: NCT03419663 Completed - Gastric Cancer Clinical Trials

Systematic Review and Meta-analysis of Cereal or Grain Consumption and Gastric Cancer

GC
Start date: September 12, 2017
Phase: N/A
Study type: Observational

This project involved a systematic literature review of published trials of cereal or grain in relation to the risk of gastric cancer. Data was extracted from the publications on PubMed, EMBASE, Cochrane Library.A traditional meta-analysis, subgroup analysis, and heterogeneity was conducted on the extracted data.

NCT ID: NCT03418428 Completed - Gastric Cancer Clinical Trials

Intestinal Microbiome After Gastrectomy

DiGMA
Start date: April 1, 2018
Phase:
Study type: Observational

The gastric barrier plays a major role in the maintanance of the distal intestinal microbiome composition. It has been shown before that the use of gastric acid suppression medication, such as proton pump inhibitors, are associated with distinctive alterations of the intestinal microbiome. Foremost, the invasion of predominantly oral bacteria, like Veillonella and Streptococcus species, were a resurring finding in previous reports. Gastric cancer treatment includes the total or subtotal resection of the stomach which can influence the gastric acid production. However, the influence by alterations in gastric milieu after this treatment on the composition of the intestinal microbiome is not well studied. Therefore, the intestinal microbiome of patients after total or subtotal gastrectomy and its influence on intestinal inflammation and gut permeability will be studied.

NCT ID: NCT03418298 Completed - Gastric Cancer Clinical Trials

Prehabilitation in Patients With Esophageal or Gastric Cancers

Start date: February 27, 2018
Phase: N/A
Study type: Interventional

Objectives: The primary objective of this study is to assess the feasibility of a internet-based preoperative exercise program in patients with esophageal or gastric cancers. Secondary objectives are to evaluate the effects of this preoperative program on functional capacity, anxiety and depression, quality of life and fatigue Methods: This feasibility study will be conduct at University Hospital Saint-Luc in Brussels. Twenty patients with esophageal or gastric cancers will participate in internet-based program 3 sessions per week. Each session will combine aerobic and resistance training. Moreover, inspiratory muscle strengthening (IMT) will be performed daily. The researcher will conduct weekly telephone calls to educate and motivate subjects. Assessments will be performed at baseline, one day before surgery, 1 month and 3 months after surgery. The following parameters will be measured: functional capacity, quality of life, fatigue, anxiety and depression.
