Treatment of esophageal cancer: the continued need for surgical resection.

We conclude that preoperative radiotherapy and chemotherapy is very likely to improve the length of survival in patients with squamous cell carcinoma undergoing surgical resection and decreases the incidence of symptomatic local recurrence requiring additional palliative treatment. A favorable tumor response to adjuvant therapy, however, did not significantly improve the survival curves in our study, does not guarantee complete tumor regression, and should not be cited as a basis for elimination of esophagectomy in treatment protocols. Adenocarcinoma treated with surgical resection has a better prognosis than similarly treated squamous cell carcinoma, but has a poorer prognosis than squamous cell carcinoma treated with preoperative adjuvant therapy and surgical resection.
