Survival and Incidence of Gastric Neuroendocrine Tumors: A Surveillance, Epidemiology, and End Results (SEER) Database Analysis

The findings show GNET incidence has continued to increase over the past two decades. Additionally, clinical factors including stage, extent of metastasis, tumor size and socioeconomic factors like age, gender, and race were associated with changes in GNET survival. In the context of the increasing incidence of GNET, these findings describe factors associated with lower- and higher-risk tumors. Further assessment of these risk factors can benefit future research to better understand why GNET incidence is increasing, aid in risk stratification of GNET patients, and improve the prognosis of GNET.
