A narrative review on advances in neoadjuvant immunotherapy for esophageal cancer: Molecular biomarkers and future directions

Abstract

Esophageal cancer has a poor prognosis and survival rate due to its high incidence in Asia, lack of early symptoms and limited treatment options. In recent years, many clinical trials have demonstrated that immunotherapy has greatly improved the survival of patients with esophageal cancer. In addition, the combination of neoadjuvant immunotherapy with other popular therapeutic regimens has shown good efficacy and safety. In this review, we summarize the progress of clinical trials and some breakthroughs in neoadjuvant immunotherapy for esophageal cancer in recent years and suggest the possibility of multimodal neoadjuvant immunotherapy regimens, as well as directions for future development.
