P14 THE IMPACT OF TRANSTHORACIC AND TRANSHIATAL ESOPHAGECTOMY ON LONG-TERM QUALITY OF LIFE ACCORDING TO EORTC QLQ-C30 AND EORTC QLQ-OG25 QUESTIONNAIRES

Abstract Aim The aim of this study was to evaluate long-term HR-QoL in patients undergoing transhiatal versus transthoracic esophagectomy in a tertiary referral center. Background & Methods Treatment of esophageal cancers is challenging. Besides (neo)adjuvant chemo(radio)therapy different surgical approaches are possible such as transhiatal (THE) or transthoracic esophagectomy (TTE) with a cervical or intrathoracic anastomosis. Studies have been performed to establish evidence which is the preferred procedure in terms of postoperative morbidity, survival and short- and long-term health-related quality of life (HR-QoL). All patients after THE or TTE for distal esophageal or gastroesophageal junction carcinoma performed between 2003 and 2016 received EORTC QLQ-C30 and EORTC QLQ-OG25 questionnaires. All questionnaires with a follow-up of more than two years after surgery were analysed. Three HR-QoL domains were chosen as primary endpoints: problems with eating, reflux and nausea and vomiting. The secondary endpoints were the remaining HR-QoL domains, postoperative complications and pathology results. The results were corrected for possible confounders such as age and gender. Results The questionnaire response rate was 47.6%, with 56 patients in the THE group and 134 in the TTE group. The mean age was 63.5 years and a median follow-up of 3.7 years (range 24-137 months) was reached. No significant difference was found in any of the HR-QoL domains or postoperative complications between the two groups. Significantly more lymph nodes were resected in the TTE group (p
