The exact [[incidence]] and [[prevalence]] for linitis plastica is unknown, however, linitis plastica is estimated to account for almost 30% of gastric cancers (previously thought to be 10%) with a declining [[incidence]]. There is a particularly high [[incidence]] rate in those individuals belonging to the Korean, Chinese and Japanese races.

Overview

The exact incidence and prevalence for linitis plastica is unknown, however, linitis plastica is estimated to account for almost 30% of gastric cancers (previously thought to be 10%) with a declining incidence. There is a particularly high incidence rate in those individuals belonging to the Korean, Chinese and Japanese races.

Epidemiology and Demographics
