title: Neoadjuvant chemotherapy before surgery for resectable carcinoma of the lower esophagus.
abstract: Neoadjuvant chemotherapy before surgery has been proposed to improve the outcome in patients with early lower esophageal cancer. To evaluate its effectiveness, we performed a systematic retrospective analysis of consecutive patients treated at the Ottawa Regional Cancer Center with prospective inclusion criteria. Between 1988 and 1992 patients were treated with surgery alone. From 1992 until 1997, patients were uniformly treated with neoadjuvant chemotherapy consisting of cisplatin and 5-fluorouracil. Surgical resection was then performed. Nineteen patients received neoadjuvant chemotherapy and 15 received surgery alone. Although the two arms of the study were balanced for age and sex, there were more patients in the neoadjuvant arm with squamous histology, weight loss and regional nodes at diagnosis. In the neoadjuvant arm, two patients did not have surgery because of progression or toxicity. However, complete resection rates were similar. There was no difference in overall survival or disease-free survival between the two arms (p > 0.4). Multivariate analysis revealed that only the nodal status at diagnosis was predictive of outcome. Neoadjuvant chemotherapy with this regimen does not result in improved survival over surgery alone.
