Early diagnosis and treatment is the key to improving the prognosis of gastric cancer. The past decades have wimessed the rapid advances in the diagnosis and management of early gastric cancer (EGC): endoscopy has played an increasingly important role, whereas laparoscopic techniques have also been introduced for EGC treatment. In China, the proportion of EGC is gradually increasing, and this condition will soon become a hot research topic. In this article, we will elucidate some major controversies in the diagnosis and management of EGC. 展开更多

Since Murakami defined early gastric cancer(EGC) as a "carcinoma limited to the gastric mucosa and/or submucosa regardless of the lymph node status", several authors have focused on the most influential histopathological parameters for predicting the development of lymph node metastases by considering the lymph node status as an important prognostic factor. A few authors have also considered the depth of invasion as one of the keys to explaining the existence of subgroups of patients affected by EGC with poor prognoses. In any case, EGC is still considered an initial phase of tumor progression with good prognosis. The introduction of modern endoscopic devices has allowed a precise diagnosis of early lesions, which can lead to improved definitions of tumors that can be radically treated with endoscopic mucosal resection or endoscopic submucosal dissection(ESD). Given the widespread use of these techniques, the Japanese Gastric Cancer Association( JGCA) identified in 2011 the standard criteria that should exclude the presence of lymph node metastases. At that time, EGCs with nodal involvement should have been asserted as no longer fitting the definition of an early tumor. Some authors have also demonstrated that the morphological growth pattern of a tumor, according to Kodama's classification, is one of the most important prognostic factors, thereby suggesting the need to report it in histopathological drafts. Notwithstanding the acquired knowledge regarding the clinical behavior of EGC, Murakami's definition is still being used. This definition needs to be upgraded according to the modern staging of the disease so that the appropriate treatment would be selected. 展开更多
