Surgical strategy for early gastric cancer

The diagnostic and therapeutic options in early gastric cancer are reviewed. In Japan, the rate of detection of early gastric cancers has increased so that minute gastric cancers can now be identified as a result of advances in diagnostic methods. The results of histopathological staging of a large number of resected specimens have led to three surgical options based on size and depth of the primary lesion, namely classical R2 resection, radical resection with limited lymphadenectomy and endoscopic surgery.
