[Limitations of surgery for cancer of the upper gastrointestinal tract].

Cancer of the upper gastrointestinal tract is one of the leading causes for cancer related deaths worldwide. While the incidence of esophageal carcinoma is increasing, the incidence of gastric cancer has been continuously decreasing over the past decades. Most patients are often diagnosed with advanced stage disease and the prognosis is still dismal. For many patients surgery is the central part of the therapy; however, improvements in the diagnostic work-up, staging techniques and therapy concepts have led to a more individualized therapeutic approach. Endoscopic treatment of early cancer is well established with high cure rates. In advanced gastric cancer the implementation of multimodal therapies, standardized surgical techniques and optimized perioperative management has led to an improvement in prognosis and outcome. The limitations of surgery in esophagogastric cancer are defined by current scientific results, recent technical developments and patient-specific characteristics. These limitations are continuously changing and require an ongoing review.
