[Esophagectomy as therapeutic principle for squamous cell esophageal cancer]

The fatalistic approach towards surgical therapy of esophageal squamous cell cancer has been replaced in recent years by a more differentiated view. This was triggered by the establishment of individualized therapeutic modalities based on tumor stage, tumor location, general patient status, and comorbidity. Despite advances in nonsurgical therapy of squamous cell esophageal cancer, esophagectomy remains the central therapeutic modality. Primary subtotal en-bloc esophagectomy with lymphadenectomy is the only curative option with a high likelihood of success for resectable tumors (uT1-3 categories) located below the level of the tracheal bifurcation and for early more proximal tumors. In patients with locally advanced tumors at or above the level of the tracheal bifurcation, surgical resection can still cure those who respond to neoadjuvant radiochemotherapy. Preoperative "conditioning" of risk patients, surgical safety strategies in risk situations, and standardization of both the operative procedure and the perioperative management have resulted in a marked reduction of the previously substantial postoperative mortality to below 3% in experienced centers. In our own experience of 900 esophagectomies for squamous cell esophageal cancer, the 5-year survival rate rose from about 20% to more than 50% in the last two decades. Esophagectomy thus has become a safe operation and remains the only therapeutic option offering cure for a substantial proportion of patients with squamous cell cancer of the esophagus.
