A phase II trial of cisplatin and 5-fluorouracil in adenocarcinoma of the oesophagus.

The effect of brief neoadjuvant chemotherapy in patients with apparently operable adenocarcinoma of the oesophagus has been investigated. Two courses of cisplatin and 5-fluorouracil (CFu) were given, followed by evaluation of the response by barium swallow. Twenty-one of 23 patients completed both courses. Two showed a complete response and five a partial response. In only one patient was there a pathological complete response. Toxicity was mild and consisted principally of nausea and vomiting. All patients underwent surgical exploration; resection was completed in 17. There were three hospital deaths (18%). Although CFu has produced two complete responses (on barium swallow) and one complete pathological clearance of tumour, the disappointing total response rate of 7/21 (33%; 95% CI 13-53) or 7/23 (30%; 95% CI 12-49) leads us to believe that further Phase II trials are needed to identify more efficacious agents and regimens.
