Advances in Research and Clinical Application of Tumor Markers in Esophageal Cancer

Abstract

Esophageal cancer is a common malignant tumor of the upper gastrointestinal tract. Early symptoms of the disease are inconspicuous and the disease is often diagnosed at a later stage, leading to higher morbidity and mortality. Esophageal cancer morbidity and mortality in both genders ranks among the top 10 most common cancers. Early detection and early treatment are effective means to reduce the incidence and mortality of esophageal cancer. Tumor markers play an important role in early diagnosis, treatment monitoring and prognosis evaluation of esophageal cancer. This paper reviews the clinical application of tumor markers related to esophageal cancer and the exploration and application progress of new tumor markers for esophageal cancer.
