Anatomy of the lymphatics in normal stomach and gastric carcinomas.

The lymphatic system is composed of lymphoid organs/tissues and a complex network of lymphatic vessels that transport interstitial fluid, antigens, lipids, immune cells, and other materials in the body. There is growing evidence that lymphatic vasculature is associated with many pathological conditions such as lymphedema and cancer progression and metastasis. Thus, improved understanding of the anatomical features, the molecular profile and the function of the lymphatic vasculature may provide innovative approaches for disease prevention and treatment. This article aims to present a comprehensive review of the gastric lymphatic anatomy and its importance in the pathology, treatment and prognosis of gastric carcinomas.
