Abstract
Background: Adjuvant therapy after surgery is effective for the treatment of advanced gastric cancer (GC), but the regimens are not uniform, resulting in imbalanced benefits.
Objectives: To compare the overall survival (OS), relapse-free survival (RFS) and disease-free survival (DFS) of patients with local-advanced GC (LAGC) after surgery plus adjuvant therapy and with surgery alone based on meta-analysis.
Material and methods: Literature search was performed among the articles published in the PubMed, Embase and Cochrane Library databases from January 2000 to December 2018. Study selection was conducted based on the following criteria: randomized clinical trials (RCTs) on surgery plus adjuvant therapy compared to surgery alone; studies compared OS and/or RFS/DFS; and cases medically confirmed with LAGC. Only articles in English were included.
Results: A total of 12 datasets from 11 randomized controlled trials (RCTs) involving 4606 patients were included in the meta-analysis. There was a significant improvement in OS of patients who underwent postoperative adjuvant therapy (HR 0.78; 95% CI: 0.72-0.84; p < 0.001). In the subgroup analysis, it showed a higher improvement in OS patients who received adjuvant chemotherapy plus immunotherapy or radiotherapy (HR 0.72; 95% CI: 0.61-0.85; p < 0.001).
Conclusion: Adjuvant therapy led to survival benefits in patients with LAGC.
期刊介绍：
Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly.
Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff.
Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj.

The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition.
In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus.
Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
