Although there has been an increasing trend of adenocarcinoma in Western populations, SCC still accounts for the majority of esophageal cancer cases globally. Cytotoxic chemotherapy has been the mainstay of treatment, however, targeted therapies including EGFR, FGFR, PI3K, or CDK4/6, despite showing preliminary efficacy signals, have not yet received regulatory approval.
