Current approaches to gastric cancer in Peru and Mexico

Survival and adequate preoperative staging in patients undergoing gastric cancer surgery at a Peruvian Police Hospital

“…Gastric cancer is one of the most frequent neoplasms in the world, with recognized areas of comparable high incidence in countries in Asia and some regions of Latin America, but with a much lower overall survival rate in countries such as Peru 4,17,18 . The low survival rate in Peru is due to a series of factors including social conditions, geographical area, and access to basic services that interact and generate an environment conducive to the development of a high incidence of this neoplasm in our population.…”

“…In Peru, the incidence of the disease has been described as close to 15.8 per 100,000 inhabitants. Likewise, gastric cancer has been associated with high mortality rates in Peru related to Andean geographical areas with a low socioeconomic level, especially in the departments of Cusco, Pasco and Huanuco 3–5 …”

“…Likewise, gastric cancer has been associated with high mortality rates in Peru related to Andean geographical areas with a low socioeconomic level, especially in the departments of Cusco, Pasco and Huanuco. [3][4][5] Five-year survival rates of 90% have been described in countries such as Japan, while despite medical advances in diagnosis and treatment, in some European and American countries, these figures range from 10% to 30% for all stages of the disease. 6,7 The management of gastric adenocarcinoma requires a multidisciplinary approach as optimal preoperative assessment involves establishing an accurate diagnosis, evaluation of the extent of the disease, and stratification of the patient's general medical condition against the proposed therapy.…”
