BACKGROUND: A regimen of epirubicin, cisplatin, and infused fluorouracil (ECF) improves survival among patients with incurable locally advanced or metastatic gastric adenocarcinoma. We assessed whether the addition of a perioperative regimen of ECF to surgery improves outcomes among patients with potentially curable gastric cancer. METHODS: We randomly assigned patients with resectable adenocarcinoma of the stomach, esophagogastric junction, or lower esophagus to either perioperative chemotherapy and surgery (250 patients) or surgery alone (253 patients). Chemotherapy consisted of three preoperative and three postoperative cycles of intravenous epirubicin (50 mg per square meter of body-surface area) and cisplatin (60 mg per square meter) on day 1, and a continuous intravenous infusion of fluorouracil (200 mg per square meter per day) for 21 days. The primary end point was overall survival. RESULTS: ECF-related adverse effects were similar to those previously reported among patients with advanced gastric cancer. Rates of postoperative complications were similar in the perioperative-chemotherapy group and the surgery group (46 percent and 45 percent, respectively), as were the numbers of deaths within 30 days after surgery. The resected tumors were significantly smaller and less advanced in the perioperative-chemotherapy group. With a median follow-up of four years, 149 patients in the perioperative-chemotherapy group and 170 in the surgery group had died. As compared with the surgery group, the perioperative-chemotherapy group had a higher likelihood of overall survival (hazard ratio for death, 0.75; 95 percent confidence interval, 0.60 to 0.93; P=0.009; five-year survival rate, 36 percent vs. 23 percent) and of progression-free survival (hazard ratio for progression, 0.66; 95 percent confidence interval, 0.53 to 0.81; P<0.001). CONCLUSIONS: In patients with operable gastric or lower esophageal adenocarcinomas, a perioperative regimen of ECF decreased tumor size and stage and significantly improved progression-free and overall survival.

PURPOSE: OEO2 is a randomized, controlled trial of preoperative chemotherapy in patients undergoing radical surgery for esophageal cancer. Random assignment was to surgery alone (S) or to two cycles of combination cisplatin and fluorouracil before surgery (CS). Initial results reported in 2002 demonstrated an advantage for both disease-free and overall survival in the CS group. The analysis has now been updated after a median follow-up of 6 years. PATIENTS AND METHODS: OEO2 recruited 802 patients, 400 on CS and 402 on S. The nature of the first recurrence event and cause of death are detailed. Survival has been determined from Kaplan-Meier curves and treatment comparisons made with the log-rank test. Survival by extent of resection is presented. RESULTS: There were 655 deaths, 335 for S and 320 for CS. The survival benefit has been maintained with a hazard ratio (HR) of 0.84 (95% CI, 0.72 to 0.98; P = .03) which in absolute terms is a 5-year survival of 23.0% for CS compared with 17.1% for S. The treatment effect is consistent in both adenocarcinoma and squamous cell carcinoma. The first disease-free survival event was macroscopic residual disease from incomplete resection (R2) or no resection in 26.4% of the S group versus 14.3% of the CS P < .001. Three-year survival by type of resection was R0 42.4%, R1 was 18.0%, and R2 was 8.6%. CONCLUSION: Long-term follow-up confirms that preoperative chemotherapy improves survival in operable esophageal cancer and should be considered as a standard of care.

INTRODUCTION: Enhanced recovery after surgery (ERAS) programs provide a format for multidisciplinary care and has been shown to predictably improve short term outcomes associated with surgical procedures. Esophagectomy has historically been associated with significant levels of morbidity and mortality and as a result routine application and audit of ERAS guidelines specifically designed for esophageal resection has significant potential to improve outcomes associated with this complex procedure. METHODS: A team of international experts in the surgical management of esophageal cancer was assembled and the existing literature was identified and reviewed prior to the production of the guidelines. Well established procedure specific components of ERAS were reviewed and updated with changes relevant to esophagectomy. Procedure specific, operative and technical sections were produced utilizing the best current level of evidence. All sections were rated regarding the level of evidence and overall recommendation according to the evaluation (GRADE) system. RESULTS: Thirty-nine sections were ultimately produced and assessed for quality of evidence and recommendations. Some sections were completely new to ERAS programs due to the fact that esophagectomy is the first guideline with a thoracic component to the procedure. CONCLUSIONS: The current ERAS society guidelines should be reviewed and applied in all centers looking to improve outcomes and quality associated with esophageal resection.
