Perioperative Chemotherapy Compared With Surgery Alone for Resectable Gastroesophageal Adenocarcinoma: An FNCLCC and FFCD Multicenter Phase III Trial

Purpose After curative resection, the prognosis of gastroesophageal adenocarcinoma is poor. This phase III trial was designed to evaluate the benefit in overall survival (OS) of perioperative fluorouracil plus cisplatin in resectable gastroesophageal adenocarcinoma. Patients and Methods Overall, 224 patients with resectable adenocarcinoma of the lower esophagus, gastroesophageal junction (GEJ), or stomach were randomly assigned to either perioperative chemotherapy and surgery (CS group; n = 113) or surgery alone (S group; n = 111). Chemotherapy consisted of two or three preoperative cycles of intravenous cisplatin (100 mg/m(2)) on day 1, and a continuous intravenous infusion of fluorouracil (800 mg/m(2)/d) for 5 consecutive days (days 1 to 5) every 28 days and three or four postoperative cycles of the same regimen. The primary end point was OS. Results Compared with the S group, the CS group had a better OS (5-year rate 38% v 24%; hazard ratio [HR] for death: 0.69; 95% CI, 0.5
