Multimodality therapy for esophageal cancer

Abstract

Esophageal cancer is undergoing a major shift in its epidemiology. Its incidence is dramatically growing and it more commonly affects younger and healthier patients. Based on the published data, there is no strong evidence to recommend routine preoperative chemotherapy for the treatment of surgically resectable esophageal carcinoma. It might be that a large-scale randomized study-which will be published in the near future-will shed some different light on this subject. The role of preoperative CRT remains undetermined. To settle this issue, larger, clinical, controlled trials are needed. Improvement in the preoperative regimen and use of new drugs should be evaluated. Concomitant CRT should be considered for potential benefit in survival and local control in patients who have localized disease and are candidates for radical non-surgical treatment. Patients with pCR following neoadjuvant therapy have a consistent, substantial survival benefit. Biologic markers can be used to predict response to therapy and might allow designation of treatment based on the individual tumor. Pretreatment staging is necessary for standardization of patients undergoing treatment protocols and for outcome evaluation. Pretreatment staging will be even more important in the future for adjusting treatment to individual patient. Video-assisted thoracoscopy and laparoscopy have been found to be the most accurate lymph node staging techniques.
