In this editorial, we comment on the article entitled “Advances and key focus areas in gastric cancer immunotherapy: A comprehensive scientometric and clinical trial review (1999-2023),” which was published in the recent issue of the World Journal of Gastroenterology. We focused on the results of the authors’ bibliometric analysis concerning gastric cancer immunotherapy, which they analyzed in depth by compiling the relevant publications of the last 20 years. Before that, we briefly describe the most recent data concerning the epidemiological parameters of gastric cancer (GC) in different countries, attempting to give an interpretation based on the etiological factors involved in the etiopathogenesis of the neoplasm. We then briefly discuss the conservative treatment (chemotherapy) of the various forms of this malignant neoplasm. We describe the treatment of resectable tumors, locally advanced neoplasms, and unresectable (advanced) cases. Special attention is given to modern therapeutic approaches with emphasis on immunotherapy, which seems to be the future of GC treatment, especially in combination with chemotherapy. There is also a thorough analysis of the results of the study under review in terms of the number of scientific publications, the countries in which the studies were conducted, the authors, and the scientific centers of origin, as well as the clinical studies in progress. Finally, an attempt is made to draw some con-clusions and to point out possible future directions.
Core Tip: Gastric cancer (GC) remains a major cause of morbidity and mortality worldwide. Conservative treatment in the form of chemotherapy has recently made remarkable advances, particularly in the field of immunotherapy. Immunotherapy of GC represents one of the most important fields of research worldwide today, particularly in China, the United States, and Japan, as well as in some Western European countries. Several treatment regimens have been approved and are being implemented with satisfactory results. Also, several treatment regimens are currently under investigation, which are expected to improve the disappointing prognosis of this malignant neoplasm.
