Controversies in the multimodality management of locally advanced esophageal cancer: evidence-based review of surgery alone and combined-modality therapy.

Most patients with esophageal cancer present with locoregional disease, and the optimal initial management is controversial. The current National Comprehensive Cancer Network (NCCN) practice guidelines support diverse treatment options for locoregional disease, including surgical resection alone, definitive chemoradiation therapy, and preoperative combined-modality (neoadjuvant/trimodality) therapy. Many cancer centers worldwide favor a neoadjuvant approach, although the evidence supporting this practice is inconsistent. A concise review of the literature is presented. The topics discussed do not necessarily reflect each author's opinions or clinical practices.
