Quality of life after surgical treatment of early Barrett's cancer: a prospective comparison of the Ivor-Lewis resection versus the modified Merendino resection.

ABSTRACT

INTRODUCTION: The Merendino (MER) procedure has been evaluated as an alternative to transthoracic esophageal resection (TER) for early stage Barrett's carcinoma. Apart from reducing morbidity and mortality, improvements concerning postoperative health-related quality of life (HRQL) have been postulated. The aim of our study was to compare HRQL between these procedures. MATERIALS AND METHODS: Between July 2000 and July 2007, 117 patients with early Barrett's carcinoma underwent surgery. Patients with tumor recurrence were excluded from the study. HRQL was assessed 1 and 2 years after surgery using the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Core Questionnaire (EORTC-QLQ-C30) and the QLQ-OES18 module. Patients recently diagnosed with early Barrett's carcinoma served as controls. Symptoms that showed a difference of more than ten between the control and the study groups were considered clinically relevant and were tested for significant differences between the study groups using the Mann-Whitney U test (p < 0.05). RESULTS: The response rates for the questionnaires ranged between 70 and 93 %. In the MER group, more items reflected a clinical relevant impairment of HRQL than in the TER group. Significant complaints in the MER group included nausea/vomiting, appetite loss, local pain, difficulties with social eating, and choking. Moreover, we found a significant restriction concerning global health and emotional and social functioning in this group 1 year after surgery. 2 years postoperatively, hardly any differences between the operative techniques could be detected. The only symptom in favor of the MER procedure was a better dysphagia score postoperatively. CONCLUSION: Our study suggests that MER procedure is not superior to subtotal esophagectomy with regard to HRQL.
