Plain English Summary

Background and study aims
The aim of this study is to investigate the relationship between human epidermal growth factor receptor 2 (HER2) overexpression and clinicopathologic factors and survival rate in patients who underwent curative gastrectomy (removal of part or all of the stomach) as treatment for gastric adenocarcinoma (stomach cancer).

Who can participate?
Patients who underwent curative gastrectomy to treat gastric adenocarcinoma at Inje University Paik Hospital over four years, from January 2012 to December 2015

What does the study involve?
HER2 expression levels measured and clinicopathologic records are collected from a gastric cancer database to identify clinicopathologic features and survival rates of the patients.

What are the possible benefits and risks of participating?
Not provided at time of registration

Where is the study run from?
Inje University Busan Paik Hospital (China)

When is the study starting and how long is it expected to run for?
March 2017 to January 2018

Who is funding the study?
Investigator initiated and funded

Who is the main contact?

Scientific title

Prognostic significance of HER2 expression in patients with resectable gastric adenocarcinoma

Acronym

Study hypothesis

The purpose of this study was to investigate HER2 overexpression by immunohistochemical (IHC) analysis in gastric adenocarcinoma tissues that were obtained by curative gastrectomy. In addition, the trialists compared clinicopathologic factors and survival rates according to HER2 expression level to identify factors associated with HER2 overexpression. Furthermore, HER2 overexpression was examined to determine its value as an independent prognostic factor.

Gastric adenocarcinoma

Intervention

Among patients who underwent curative gastrectomy to treat gastric adenocarcinoma at Inje University Paik Hospital over four years, from January 2012 to December 2015, 782 patients underwent an immunohistochemical analysis to evaluate HER2 expression levels. Clinicopathologic records that were collected from a gastric cancer database were retrospectively reviewed to identify clinicopathologic features and survival rates of the patients.

Primary outcome measure

HER2 overexpression measured by immunohistochemical (IHC) analysis in gastric adenocarcinoma tissues obtained by curative gastrectomy at baseline

Secondary outcome measures

Clinicopathologic factors and survival rates collected from a gastric cancer database at August 2017

IPD sharing plan

The datasets generated during and/or analysed during the current study are/will be available upon request from Prof. Kwang-Hee Kim. Surgeons perform gastricectomy and collect personal data. Then, if necessary, manually extract and use the data. So when you ask for data, it is possible to verify that the patient is not identified. The individual has all the data but there is no formalized program. Data is stored on a personal computer. It may be disclosed on demand. However, it is not considered easy to use the data as it is not intended to identify the patient.
