216 Feasibility of Routine Symptom Monitoring in Oesophago-Gastric Cancer Patients: Looking Toward Routine Postoperative Monitoring

Abstract Aim Patients experience severe and life altering symptoms post oesophago-gastric cancer (OGC) surgery which can negatively affect quality-of-life. This study aims to assess the feasibility and usability of symptom monitoring post-OGC surgery at a tertiary OGC centre. Method Patients who attended OGC quality-of-life clinic or had surgery within last 2 years were eligible for inclusion. Participants completed a validated 40 item EORTC IL278 symptom questionnaire in paper (n=35) or electronic (n=42) format via emailed link to REDCAP. An evaluative questionnaire collected data on questionnaire usability and delivery method. Data was analysed on SPSS. Results Of the 77 participants, 64% had oesophagectomy and 27% had gastrectomy between 2018 and January 2025. Median age was 66.51. Most frequently reported symptoms were early satiety (77.9%) and tiredness (76.62%). 62% completed the questionnaire electronically, 45.4% on paper with completion rates of 71.2% and 100% respectively. Mean completion time was 7.8 minutes (SD 3.8), 90% reported no difficulty. 64% found the questionnaire helpful at describing their symptoms, 27.27% reported that completing the questionnaire itself improved their care. There was no significant difference in these results between those within or beyond 2 years of surgery (p .95, p.1). 76.6% supported future symptom monitoring intervals of 3 months and electronic questionnaire delivery (75%). Conclusions This study demonstrated the feasibility of symptom monitoring in patients post OGC surgery. Patients expressed a willingness to complete the questionnaire at 3 monthly intervals, further research will assess whether questionnaire completion would be maintained over time if used for long-term symptom monitoring.
