Postoperative pulmonary complications in patients with esophageal cancer.

There are recent reports on postoperative pulmonary complications in patients with esophageal cancer who were treated preoperatively with chemotherapy and irradiation. The Hamburg Esophageal Study Group is currently undertaking a prospective randomized study to evaluate the efficacy of preoperative treatment. Postoperative pulmonary complications and mortality in these patients with either a combined preoperative treatment (group 1, n = 11) or chemotherapy alone (group 2, n = 9) are evaluated in the present paper. Complete remission of the tumor was found more often in group 1 (54.6%) than in group 2 (22.2%). However, postoperatively the patients of group 1 developed adult respiratory distress syndrome (ARDS; 54.6%) more frequently than in group 2 (11.1%), and all patients with ARDS died. Thus, although the combined preoperative treatment is more effective in tumor remission, it is associated with a higher respiratory failure and postoperative mortality. Therefore, the preoperative regime has now been changed by the study group. Since after the clinical manifestation of ARDS no causative clinical therapy is available up to now, attention must be focused on the prevention of respiratory failure.
