Locally advanced esophageal cancer is usually dealt with multimodal therapies. The current treatment of choice is neoadjuvant chemoradiation with surgery, but several other choices are also available for adenocarcinoma. For example, adjuvant therapy can be added to the patients received upfront surgery or neoadjuvant therapy in certain conditions. However, squamous cell carcinoma has no such flexibility. This article will address the reason to this remarkable difference, also the current evidence and perspective of adjuvant therapy for esophageal squamous cell carcinoma...
