Neoadjuvant treatment for esophageal squamous cell carcinoma

Squamous cell carcinoma and adenocarcinoma are types of esophageal cancer, one of the most aggressive malignant diseases. Since both histological types present entirely different diseases with different epidemiology, pathogenesis and tumor biology, separate therapeutic strategies should be developed against each type. While surgical resection remains the dominant therapeutic intervention for patients with operable esophageal squamous cell carcinoma (ESCC), alternative strategies are actively sought to reduce the frequency of post-operative local or distant disease recurrence. Such strategies are particularly sought in the preoperative setting. Currently, the optimal management of resectable ESCC differs widely between Western and Asian countries (such as Japan). While Western countries focus on neoadjuvant or definitive chemoradiotherapy, neoadjuvant chemotherapy followed by surgery is the standard treatment in Japan. Importantly, each country and region has established its own therapeutic strategy from the results of local randomized control trials. This review discusses the current knowledge, available data and information regarding neoadjuvant treatment for operable ESCC. (C) 2014 Baishideng Publishing Group Inc. All rights reserved.
