Risk Factors and Screening Strategies for Early Detection of Esophageal Carcinoma

Abstract

spa:El cáncer de esófago es el octavo tipo de cáncer más frecuente en el mundo y el sexto causa de muerte por cáncer, con distribuciones variables según zonas geográficas región. Iniciativas para la detección precoz, tratamiento, control y seguimiento de diferentes patologías ha demostrado un impacto significativo en la reducción de la morbilidad y la mortalidad en diferentes patologías, aunque no existen protocolos establecidos para el esófago tamizaje de cáncer en población general, factores de riesgo asociados al desarrollo de esta condición están bien definidos, y esto permite identificar y priorizar la población con mayor riesgo.

eng:Esophageal cancer is the 8th most frequent type of cancer in the world and the 6th cause of death from cancer, with variable distributions according to geographic region, it ́s mortality rate remains high because is rarely diagnosed at early stages. It has been reported that nearly 40% of patients have metastasized at the time of diagnosis; this added to the special anatomical conditions of the mediastinum and the high recurrence rate, confers it a worse prognosis and 5-year survival rate close to 20%. Initiatives for early detection, treatment, control and monitoring of different pathologies has shown a significant impact on reduction of morbidity and mortality in different pathologies, although there are no established protocols for esophageal cancer screening in general population, risks factors associated with development of this condition are well defined, and this allows identify and prioritize population with highest risk
