AbstractA number of studies have been conducted to explore the survival of gastric cancer (GC) patients, while studies about non-cancer causes of death in patients with GC are not well-conducted. The aim of this study was to deeply investigate the causes of death (COD) in GC patients, especially non-cancer ones. The Surveillance, Epidemiology and End Results (SEER) database was used to extract information including demographics, tumor characteristics and causes of death of GC patients meeting the inclusion criteria. The patients were stratified by demographic and clinical parameters. Standardized mortality ratios (SMRs) were calculated for all causes of death at different follow-up periods. A total of 116,437 patients with GC diagnosed between 2000 and 2020 were retrieved from the SEER database. Of these, 85,827 deaths occurred during the follow-up period, most of which occurred within 1 year after GC diagnosis. GC (n = 49,746; 58%) was the leading COD, followed by other cancer (n = 21,135; 25%) and non-cancer causes (n = 14,946; 17%). Diseases of heart were the most common non-cancer cause of death, accounting for 30%, followed by cerebrovascular diseases (n = 917; 6%) and chronic obstructive pulmonary disease (n = 900; 6%). Although gastric cancer remains the most common cause of death in gastric cancer patients, it should not be ignored that the risk of non-cancer causes tends to increase with the length of the latency period. These findings may provide important insights into the healthcare management of gastric cancer patients at various follow-up intervals.Copyright © 2024 the Author(s).
