%X Gastric cancer is a disease with high incidence and mortality in our population. The prognosis of patients with this disease is closely related to the neoplasm stage at diagnosis, including the following characteristics of the tumor: extension into the gastric wall thickness, spread to locoregional lymph nodes and the ability to generate distant metastases, as described by the TNM classification. For localized tumors characterized only by invasion of mucosa or submucosa at diagnosis, survival at 5 years is between 70 and 95% with exclusive surgical management; however, when extension into the gastric wall is higher and/or there is locoregional nodal involvement, survival decreases to 20-30% at 5 years. Currently, at high-volume centers, the extent of gastrectomy is individualized based on several parameters, which in an increasing number of cases allows a total gastrectomy with D2 lymphadenectomy and preservation of the spleen and pancreas. This improved procedure increases the chance of R0 surgery and improves the relationship between resected and affected lymph nodes, resulting in a decreased risk of the long-term locoregional recurrence. To improve these results, different therapeutic strategies combining chemotherapy or chemoradiotherapy with surgery have been tested. Previously, the Intergroup 0116 clinical trial, published in 2001, which changed clinical practice in the United States, showed that adjuvant chemoradiotherapy improved survival (from 26 to 37 months overall survival) of these patients. In Europe, perioperative chemotherapy has been considered the standard treatment, since the publication of two randomized phase III trials showed an increase at 5 years survival in the group treated with chemotherapy.
