Abstract
Gastric cancer is one of the leading causes of death for cancer worldwide, although geographical variations in incidence exist. Over the last decades, its incidence and mortality have gradually decreased in Western countries, while these have increased, or remained stable, in the other world regions. Gastric cancer is often diagnosed at an advanced stage, with the only notable exception of Japan, where nationwide screening programs are enforced, due to local high incidence. Curative- intent surgery (i.e., gastrectomy, total or partial, and lymphadenectomy) remains the cornerstone of treatment of gastric cancer. Much has been debated about the extent of lymph node dissection and, although it is a valuable contribution to staging and cure, operative treatment only represents one aspect of overall effective management, as the risk of both locoregional and distant recurrences are high, and bear a poor prognosis. As a matter of fact, surgery, as a single modality treatment, has probably achieved its maximum efficacy for local control and survival, while other accompanying nonsurgical treatment modalities have to be taken into account, although their role is still the subject of considerable debate. The authors in this review present an update on the outcome of treatment of gastric cancer in relation to the extent of lymphadenectomy and of various nonsurgical preoperative, intraoperative, and postoperative strategies.
