The most eminent drawback of majority commonly cited randomized trials is heterogenicity of cancer patients population. Most of them overlap between esophageal adenocarcinoma and squamous cell carcinoma or between adenocarcinoma of the esophagus, esophagogastric junction and the stomach. When the investigators reviewed the composition of the most prominent 10 studies population including 3171 patients with easophageal and gastric cancer the investigators identified 911 (28.7%) patients with AEG. The remaining pooled population involved 1173 (36.9%) patients with adenocarcinoma of the esophagus, 598 (18.9%) patients with squamous cell carcinoma of the esophagus and 775 (24.4%) patients with adenocarcinoma of the stomach. Only 1 randomized controlled trial concerned exclusively patients with AEG. In this study preoperative chemoradiotherapy resulted in a 16% increase of 3-year survival. Although its superiority was not proven (p=0.07), these data provide evidence that preoperative chemoradiotherapy may improve survival and should be further investigated. Interestingly, the survival benefit was evident although the postoperative mortality was more than doubled (10.2% versus 3.8%) by adding chemotherapy. Although this study did not meet its accrual goals and could not provide statistical significance, the improvement in both local cancer free and overall survival suggest that preoperative chemoradiotherapy appears most valuable modality treatment to cure patients with localized AEG. As it is more than evident that major response to preoperative treatment is an important prognostic factor future trials should aim to optimize preoperative treatment by combining all treatment modalities.
