Impacts of complications after esophageal cancer surgery on health-related quality of life and nutritional status

The long-term impacts of post-operative complications, especially pulmonary complications and anastomotic leakage, on health-related quality of life (HRQoL), nutritional status and body composition remain to be fully addressed in patients undergoing esophageal cancer surgery. Patients who underwent esophagectomy between 2015 and 2019 and survived without recurrence were eligible. HRQoL (European Organization for Research and Treatment of Cancer QLQ-C30 and the QLQ-OES18 questionnaires), nutritional and body composition data were prospectively evaluated before and at 3, 6, 12 and 24 months after surgery. Collected data were compared between patients with post-operative complications and those without. In total, 88 patients were included. Overall complications, anastomotic leakage and pulmonary complications developed in 48 (54.5%), 20 (20.7%) and 18 (20.5%) patients, respectively. Patients with pulmonary complications had significantly more reflux-related symptoms (dry mouth; P = 0.03, coughing; P = 0.047), and more difficulties with eating at 24 months after surgery, as compared to those without such complications. Anastomotic leakage increased pain, speaking problems and dysphagia up to 6 months after surgery. Patients with pulmonary complications had significantly lower prealbumin levels (P = 0.01, 0.02 and 0.008 at 6, 12 and 24 months after surgery, respectively) and lower prognostic nutritional index values over time after surgery than those without these complications. In contrast, anastomotic leakage was not associated with poor nutritional status post-operatively. Body composition was not affected by the occurrence of complications. Patients who developed post-operative complications, especially pulmonary complications, had long-lasting negative HRQoL outcomes and poor nutritional status after esophagectomy.
