Background: We investigated the efficacy and tolerability of cisplatin and 5-fluorouracil (5-FU) plus bevacizumab as neoadjuvant therapy for patients with locally advanced resectable esophageal cancer. Patients and Methods: In this prospective phase II study, 22 patients with adenocarcinoma and 6 with squamous cell carcinoma received 2 4-day cycles of bevacizumab 7.5 mg/kg followed by cisplatin 80 mg/m2 infusion on day 1 followed by 5-FU 1,000 mg/m2 as a 96-h continuous infusion on days 1–4, separated by a 3-week interval. Results: The response rate was 39%, the R0 resection rate was 43%, and the median overall survival (OS) was 17 months. The regimen was well tolerated, with the most common severe toxicities being venous thromboembolism (10%), nausea, and gastrointestinal bleeding (7% each). In 37 patients previously treated with cisplatin and 5-FU alone at our institution and thus serving as historical controls, the response rate was 30%, the R0 resection rate was 44%, and the median OS was 23 months. There was no statistically significant difference between the 2 groups of patients. Conclusion: Adding bevacizumab to cisplatin and 5-FU neoadjuvant chemotherapy was active and well tolerated but did not seem to improve the resection rate or OS compared with prior regimens, including the historical controls at our institution.
