Neoadjuvant chemotherapy and surgery of cancer of the esophagus.

Overview

Neoadjuvant, or preoperative, chemotherapy for esophageal cancer has become an area of increasing interest because of the failure of conventional therapy (surgery or radiation) to improve disease-free or overall survival. Several autopsy series have demonstrated that, in many symptomatic western patients, esophageal cancer is a systemic disease. Neoadjuvant chemotherapy thus, in theory, allows a simultaneous attack on both the primary and metastatic disease. A number of single-arm, phase II multimodality trials have been completed. Toxicities of chemotherapy, while substantial, have been tolerable. With careful attention to detail, operative morbidity and mortality has not been increased. Large-scale randomized trials are needed to evaluate the impact of this technique on disease-free and overall survival.
