The high cancer related mortality has remained a significant issue of health care in Poland, Europe and worldwide. The decreasing incidence rate for carcinoma of the distal stomach and a marked trend of increasing incidence for adenocarcinoma of the esophago-gastric junction and esophagus has been observed in the developed countries. The most eminent drawback of majority commonly cited randomized trials is heterogenicity of cancer patient population. The epidemiological, pathological, and clinical data clearly suggest that adenocarcinoma of the esophago-gastric junction is the entirety different both from adenocarcinoma of the esophagus and adenocarcinoma of the stomach. The experience in a combined modality therapy for adenocarcinoma of the esophago-gastric junction have been extrapolated from studies on esophageal or gastric cancer, where the investigated population involved in part patients with carcinoma of the esophago-gastric junction. The proposed study has been designed to achieve the following objectives:
