Author(s): Zhang L, Luo W, Cao A and Tan D*
Gastric cancer (GC) is the fifth most commonly diagnosed cancer worldwide and the second leading cause
of cancer-related deaths. Adenocarcinoma accounts for approximately 95% of all malignant gastric neoplasms.
Most localized GC (stages II and III) are best treated with multimodality therapy with a 5-year survival in
approximately 40% of patients; however, advanced GC only has limited treatment options with poor prognosis.
GC is a highly heterogenous disease. Historically, many classification systems have been proposed, including
anatomical classification (Borrmann classification, Siewert and Stein classification), histological classification (WHO
classification, Laurén’s classification), and extent of disease (early gastric cancer vs. advanced cancer). Originally
proposed in 1965, the Laurén’s classification divides GC into intest.. Read More»
