Active clinical trials for "Stomach Neoplasms"

There is no consensus on what type of function-preserving gastrectomy can provide the best patient quality of life (QOL). This study aims to evaluate the incidence of dumping syndrome after vagus nerve-preserving distal gastrectomy (VPNDG).

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

Gastric cancer is most frequent after the fifth decade of life. Surgical risk is higher in aged population because of general health condition may affect the postoperative result. Aim of the study was to identify risk factors for post-operative mortality in octogenarian patients who underwent surgery for gastric cancer.

An objective analysis of postoperative complications is vital to escort octogenarian for gastric cancer surgery. Investigator carefully collected clinical data prospectively to pave way for standard management in high risk patients.

The purpose of the study is to evaluate the diagnostic performance of a Raman spectroscopy analysis device - Spectra IMDx for the detection of gastric cancer and precancerous lesions in vivo.

To explore the associations among bile acid profile, bile acid-microbiota cross-talk and the development of gastric cancer, so as to better prevent the occurrence and development of gastric cancer

We investigate whether the intravenously administered human albumin is beneficial to prevent anastomotic leakage after gastric cancer surgery.

This was a retrospective case-control study designed and conducted under the approval of the ethic committee of Tehran University of Medical Sciences. All patients with gastric cancer referring to Cancer Institute, Tehran University of Medical Sciences, Tehran, Iran, during February 25th and December 25th 2020, were enrolled to the study.

Frailty is common in patients with gastric cancer undergoing surgical treatment. Preoperative frailty can lead to many adverse outcomes in patients after surgery. This study aims to comprehensively and systematically analyze the influencing factors of preoperative frailty in patients with gastric cancer based on the health ecology theory , to change some critical variable factors in the future, improving the overall prognosis of patients.

The primary objective is to evaluate the concordance between human epidermal growth factor receptor 2 (HER2) status determined by the participating laboratory and by the centralized laboratory. HER2 status of samples was tested by the participating laboratories (investigator's choice of immunohistochemistry [IHC] and in situ hybridization [ISH] methods) and by the centralized laboratories (IHC using the 4B5 anti-HER antibody and Silver ISH). Positive HER2 status was defined as a score of IHC3+ or IHC2+/ISH+.
