Tree-based model for diffuse-type gastric cancer prognostication: a population study based on the Surveillance, Epidemiology, and End Results database

Diffuse-type gastric cancer (DGC), a subtype of the Lauren classification, is characterized by poor differentiation and a poor prognosis, and effective therapeutic options remain limited. This study aimed to explore the prognostic risk stratification of DGC and to evaluate the effects of various clinical factors on prognosis.
