Factors associated with local-regional failure after definitive chemoradiation for locally advanced esophageal cancer

Background Locally advanced esophageal cancer is often treated with a trimodality approach. While a substantial proportion of such patients initially achieve a clinical complete response (cCR) after chemoradiation, only a small proportion achieve durable control. We analyzed patients who reached cCR after definitive chemoradiation for esophageal cancer to identify clinical predictors of local disease recurrence.
