Health-related quality of life assessment at presentation may predict complications and early relapse in patients with localized cancer of the esophagus

Health-related quality of life (HR-QOL) assessment in esophageal cancer is increasingly performed. However, the association of baseline HR-QOL in predicting outcome is unclear. This study aimed to assess the impact of HR-QOL scores at diagnosis with major morbidity, mortality, failure to progress to surgery, recurrence within 1 year, and survival in patients with localized esophageal cancer. The European Organization for Research and Treatment of Cancer's quality of life questionnaire was completed at diagnosis. Univariate and multivariate logistic regression were used to investigate the relationship between baseline HR-QOL and outcomes adjusting for confounding variables. A total of 185 patients with localized esophageal cancer were included, 89 undergoing multimodal therapy and 96 surgery alone. Global QOL scores were significantly associated with in-hospital mortality (P = 0.020) but not with major morbidity (P = 0.709) or 1-year survival (P = 0.247). Symptoms of fatigue and dyspnea at baseline were significantly (P < 0.05) associated with major morbidity, in-hospital mortality, and survival in univariate analysis. After adjusting for known confounding variables in multivariate analysis, only worse dyspnea score remained predictive of in-hospital mortality and a worse fatigue score remained predictive of 1-year survival. HR-QOL was of no benefit in predicting survival in multivariate analysis that identified pathological nodal status as the most significant factor. HR-QOL questionnaires may be helpful in preoperative assessment of risk. It is possible that patients with unrecognized micrometastatic disease at the time of surgery may report worse systemic symptoms at diagnosis, in particular fatigue and dyspnea, and these and global QOL scores may also identify poorer reserves that may increase in-hospital morbidity and mortality postoperatively.
