  Gastric malignancies are currently the third leading cause of cancer-related deaths worldwide. Several classification proposals have been made, initially morphological and currently molecular, with the latter aiming to integrate neoplasms with specific molecular and prognostic characteristics. The most recent and widely disseminated one subdivides them into 4 groups: EBV-positive adenocarcinomas; adenocarcinomas with high microsatellite instability; adenocarcinomas with chromosomal instability; and genomically stable adenocarcinomas. The objective is to achieve better classification and consequently greater definition in risk stratification, treatment, and prognosis. The high costs involved in the genomic and molecular analyses necessary for complete molecular classification, especially for chromosome instability and genomically stable subtypes, are certa..
