Perioperative versus Preoperative Chemotherapy with Surgery in Patients with Resectable Squamous Cell Carcinoma of Esophagus: A Phase III Randomized Trial
2015
Background Perioperative chemotherapy for resectable squamous cell carcinoma of esophagus remains elusive. Thus, we assessed whether a perioperative regimen of paclitaxel, cisplatin, and 5-fluorouracil (PCF) improved outcomes among patients with curable squamous cell carcinoma of esophagus comparing with preoperative chemotherapy alone. Methods Overall, 346 patients with resectable squamous cell carcinoma of esophagus were randomly assigned to receive surgery plus perioperative chemotherapy (175, arm A) or preoperative chemotherapy (171, arm B). Both arms received two preoperative cycles of PCF: intravenous paclitaxel (100 mg per square meter of body surface area) and cisplatin (60 mg per square meter of body surface area) on day 1, and a continuous intravenous infusion of 5-fluorouracil (700 mg per square meter of body surface area per day) for 5 days. Arm A received two added postoperative cycles of PCF. The primary end point was relapse-free survival, and the secondary end point was overall survival. Results Compared with preoperative chemotherapy group, perioperative chemotherapy group had a greater likelihood of 5-year relapse-free survival (hazard ratio for relapse, 0.62; 95% confidence interval, 0.49–0.73; 31% versus 17 %, p p Conclusion In patients with operable esophageal squamous cell carcinoma, perioperative regimen of PCF can significantly improve 5-year relapse-free and overall survival comparing with preoperative chemotherapy alone.
