Abstract
Evaluation of: Clavier JB, Antoni D, Atlani D et al. Baseline nutritional status is prognostic factor after definitive radiochemotherapy for esophageal cancer. Dis. Esoph. doi:10.1111/j.1442-2050.2012.01441.x (2012) (Epub ahead of print).
The influence of nutritional status of patients with esophageal cancer on the effect of chemoradiation is not well studied. In a retrospective study of 143 patients with definitive chemoradiation, the authors show that malnutrition is a negative prognostic factor. In the Western industrial world, the incidence of high BMI has greatly increased over the past few decades, together with the incidence of esophageal adenocarcinoma. Studies analyzing the influence of being overweight on the outcome after esophagectomy showed that a very high BMI has a negative impact on a patient’s survival. The interpretation of results from prognostic studies will be more complicated if several therapeutic procedures are combined, for example, neoadjuvant or adjuvant therapies combining chemoradiation or chemotherapy and esophagectomy. Prospective randomized studies including the nutritional status and immune competence for patients with advanced cancer of the esophagus are necessary.
