AIM:To compare neoadjuvant chemoradiotherapy and surgery with surgery alone for resectable esophageal carcinoma. METHODS:We used MEDLINE and EMBASE databases to identify eligible studies and manual searches were done to ensure no studies were missed.Trial validity assessment was performed and a trial quality score was assigned. RESULTS:Eleven randomized controlled trials(RCTs) including 1308 patients were selected.Neoadjuvant chemoradiotherapy significantly improved the overall survival compared with surgery alone.Odds ratio(OR) [95%confidence interval(CI),P value],expressed as neoadjuvant chemoradiotherapy and surgery vs surgery alone,was 1.28(1.01-1.64,P=0.05)for 1-year survival,1.78(1.20-2.66,P=0.004)for 3-year survival,and 1.46(1.07-1.99,P=0.02)for 5-year survival.Postoperative mortality increased in patients treated by neoadjuvant chemoradiotherapy(OR: 1.68,95%CI:1.03-2.73,P=0.04),but incidence of postoperative complications was similar in two groups (OR:1.14,95%CI:0.88-1.49,P=0.32).Neoadjuvant chemoradiotherapy lowered the local-regional cancer recurrence(OR:0.64,95%CI:0.41-0.99,P=0.04), but incidence of distant cancer recurrence was similar (OR:0.94,95%CI:0.68-1.31,P=0.73).Histological subgroup analysis indicated that esophageal squamous cell carcinoma did not benefit from neoadjuvantchemoradiotherapy,OR(95%CI,P value)was 1.16(0.85-1.57,P=0.34)for 1-year survival,1.34 (0.98-1.82,P=0.07)for 3-year survival and 1.41 (0.98-2.02,P=0.06)for 5-year survival. CONCLUSION:Neoadjuvant chemoradiotherapy can raise the survival rate of patients with esophageal adenocarcinoma.

Neoadjuvant chemoradiotherapy significantly improved the overall survival compared with surgery alone. Odds ratio (OR) [95% confidence interval (CI) neoadjuvant chemoradiotherapy and surgery vs surgery alone, was 1.28 (1.01-1.64, P = 0.05) for 1-year survival, 1.78 (1.20-2.66, P = 0.004) for 3-year survival, and 1.46 (1.07-1.99, 0.02) for 5-year survival. Postoperative mortality increased in patients treated by neoadjuvant chemoradiotherapy (OR: 1.68, 95% CI: 1.03-2.73, P = 0.04) 95% CI: 0.88-1.49, P = 0.3 2) .Neoadjuvant chemoradiotherapy lowered the local-regional cancer recurrence (OR: 0.64, 95% CI: 0.41-0.99, P = 0.04) but incidence of distant cancer was similar (OR: 0.94, 95% CI: 0.68-1.31 , P = 0.73) .Histological subgroup analysis indicated that esophageal squamous cell carcinoma did not benefit from neoadjuvant chemotherapy, OR (95% CI, P value) was 1.16 (0.85-1.57, P = 0.34) for 1-year survival, 1.34 -1.82, P = 0.07) for 3-year survival and 1.41 (0.98-2.02, P = 0.06) for 5-year survival.
