[Research progress of identifying predictive biomarkers for induction therapy in esophageal cancer]

Surgery is still the major treatment for esophageal cancer. It remains controversial, whether induction radiochemotherapy before resection can improve long-term survival for esophageal cancer patients. Researches have found that preoperative treatment only increases survival rates for patients who respond to induction therapy, but not for non-responders. Therefore, to identify the predictive biomarkers for induction therapy draw much attention. Although still far from satisfactory results, some have been obtained. Here, we summarize the potential biomarker candidates for reference.
