Active clinical trials for "Stomach Neoplasms"

Incidence of positive surgical margins after curative gastrectomy ranges from 1% to 20%. It has been suggested that positive surgical margins is an adverse prognosis factor, with a higher local recurrence and worse overall survival (OS). However, the management of these patients remains unclear.

There are a lot of surgical techniques in minimally-invasive surgery to remove gastric subepithelium tumor. Surgical approach depend on location and size of tumor. Usefully used Endostapler to cut stomach include lesion. For tumors in difficult locations some surgeons prefer laparoscopic and endoscopic cooperation or use the intragastric port technique to identify and remove the mass. But in complex procedures, gastotomy and hand sawn to identify and remove gastric subepithelium tumor is a simple technique and easy to apply. This study demonstrates the safety and effectiveness of this technique.

Gastric cancer is the fifth most common cancer worldwide. Gastrectomy with lymphadenectomy is still the most effective treatment modality, depending on the stage and location. Despite many radiological, surgical and anesthetic innovations, serious complications such as anastomotic leakage, intra-abdominal abscesses, wound complications are seen secondary to gastrectomy. Many clinical studies have been conducted to prevent and predict these complications. The Model for End-Stage Liver Disease (MELD) score, in which bilirubin, international normalized ratio (INR) and serum creatinine values were used to determine surgical risks in patients scheduled for liver transplantation. Latter developed by adding serum sodium (Na) to the formula. The MELD-Na score is used to predict postoperative complications in non-cirrhotic patients because of its simple and easy calculation.Moreover, The Meld-Na score was later used to predict complications for surgical procedures other than liver surgery such as colorectal surgery. In this study, we aimed to investigate the importance of the Meld-Na score in predicting the perioperative and postoperative outcomes in patients with gastric cancer.

Adding the handgrip strength (HGS) asymmetry to the existing measurements of low HGS may improve the assessment of muscle function.

To prospectively evaluate the effect of the gastric cancer specialist training program of Fujian Medical University Union Hospital on laparoscopic gastric cancer surgery.

The purpose of this study is to determine whether detection of pepsinogen Ⅰand Ⅱ combined with Helicobacter pylori antibody, so-called ABC method , is fit on gastric cancer screening in community of Wuxi City.

As the number of obesity continues to increase, surgical oncologist pay more attention to the effect of obesity on surgical outcomes and survival of digestive systemin cancers. Body mass index(BMI) is one of the most widely used measurements of obesity. Abdominal fat area (AFA) calculated by computed tomography is popular because of its validity of fat distribution. There is still no consensus which of BMI and AFA could be the more effective measurement and more accurate to evaluate effect of obesity on surgical outcomes and survival. Gastric cancer is one of the most common digestive system cancers, and gastrectomy is the primary therapeutic options.It is important to compare the different measurements(BMI or AFA) to assess obesity and effect on surgical outcome and survival for gastric cancer patients.

Background: Stomach cancer is common around the world. The US is a low-risk region. But the 5-year survival rate in the US is low. This is because the cancer is usually in a late stage by the time it is diagnosed. One way to detect it earlier is to screen many people with a procedure called endoscopy. But this may not be feasible in low-risk or developing countries. Researchers want to find a biomarker for early-stage disease to help them create an effective way of screening. DNA methylation is a chemical modification of DNA. It generates a signal for certain cancers, including stomach cancer. Researchers want to find a blood-based DNA methylation marker for stomach cancer. Objective: To study plasma DNA methylation as a potential biomarker for detection of stomach cancer. Eligibility: Participants from 2 studies already done in China Design: Researchers will use blood samples from participants in the 2 studies. The blood was collected in 1999/2000. They will use samples from some who developed stomach cancer between those years and 2006. The other samples will be from some who stayed cancer free in that time. Participants already gave written informed consent. Researchers will take DNA from the samples. They will look for methylation.

This study will assess the efficacy and toxicity of perioperative chemotherapy with Epirubicin + Cisplatin + Capecitabine (ECX) in routine clinical practice in a network of public hospitals in Santiago, Chile.

Serum pepsinogen (PG) levels are considered reliable markers for progression of atrophic gastritis with a stepwise reduction in the serum PG I level or PG I/II ratio. A combination of serum PG levels and Helicobacter pylori serology are used as a biomarker strategy for detection of individuals at increased risk of gastric neoplasm based on Correa's hypothesis. The investigators aimed to uncover whether this combination method could predict the risk of gastric neoplasms and the progression of chronic atrophic gastritis after 3 years. All the participants will be followed for an expected average of 3 years.
