BackgroundObesity and overweight are risk factors for developing an oesophageal cancer, especially the adenocarcinoma in the distal oesophagus or at the gastroesophageal junction, and many patients still are overweight at the clinical presentation even if they are losing weight. Main mechanisms involved in weight loss are a decreased nutrients' intake and an alteration in metabolism due to a cytokine-driven inflammatory status. Malnutrition is a risk factor for a poor compliance to chemotherapy and radiation therapy and finally for the oncologic outcome. There is scientific evidence that frequently both conditions exist but in the advanced stages of disease metabolic alterations play a major role and are responsible for the poor response to nutritional support.MethodsThe literature about the nutritional support in patients with cancer of the oesophagus has been reviewed with special emphasis on randomised clinical trials whenever available. In surgical patients, both overweight and weight loss increase the risk of postoperative complications.ResultsIn non-dysphagic patients receiving a neo-adjuvant oncologic treatment, the simple use of oral nutritional supplements is little effective in ameliorating the nutritional status, in contrast, an intensive dietetic surveillance associated with oral supplements can lead to better nutritional status, improved quality of life and better compliance with therapy. In dysphagic patients, many comparative non-randomised clinical studies have shown clinical benefits from tube feeding on the nutritional status and compliance with therapy. There is no apparent difference on the metabolic efficacy of the enteral versus parenteral nutrition. Studies on peri-operative nutrition in oesophagectomy patients were often underpowered and, hence, inconclusive, but the large experience on the nutritional support in patients with gastrointestinal cancer undergoing major abdominal surgery has clearly shown the benefits of the enteral nutrition. Both the American and the European Society for Parenteral and Enteral Nutrition have recognised a grade A recommendation for the nutritional support of malnourished gastrointestinal cancer patients undergoing major surgery.ConclusionsIn patients with oesophageal cancer on chemotherapy and/or radiation therapy, enteral nutrition (oral supplements +/- intensive counselling or tube feeding) is nutritionally and clinically beneficial. In surgical patients, a broad experience in major abdominal surgery supports the peri-operative use of enteral nutrition and especially of immune-enteral nutrition.
