Cohort Study of Neoadjuvant Treatment Modalities for Esophageal Cancer
Esophageal cancer is the most prevalent cancer globally with poor survival outcome. The prognosis with surgery alone is poor, accounting for 30-40% of overall survival at 5 year. Either neoadjuvant chemotherapy (nCT) or chemoradiotherapy (nCRT) has been shown as efficatious therapy to improve patients outcomes in esophageal or esophagogastric junction cancer as compared with surgery alone. The purpose of this study was to explore the optimal neoadjuvant treatment modalities including PD-1/PD-L1 antibody or targeted drug for patients with esophageal or esophagogastric junction cancer.
