OGC SO05 - Prevalence of Malabsorption and Impact on Quality of Life After Oesophago-Gastric Cancer Surgery

Abstract Background Recent Cancer Research UK data highlights a concerning rise in oesophago-gastric cancers, with 9,200 new cases of oesophageal cancer cases and 7,000 new cases of gastric cancer annually, ranking them the 13th and 17th most prevalent cancers, respectively. Surgery offers potential cure, but survival rates remain modest. Procedures include oesophagectomy and gastrectomy with Roux-en-Y reconstruction. Patients frequently experience nutrition-impact symptoms (NIS) associated with malabsorption post-surgery, however limited data exits on how this malabsorption affects their quality of life (QoL). This study aimed to investigate the prevalence of malabsorption and its correlation with QoL following oesophago-gastric cancer surgery. Method A cross-sectional cohort observational study was conducted on 98 cancer-free patients aged 18 or older following oesophagectomy (57%, including 1% with colonic interposition), subtotal gastrectomy (21.4%), or total gastrectomy (20.4%) with curative intent at the Northern Oesophago-Gastric Unit in Newcastle Upon Tyne from January 2013 to December 2023. Data collection utilised a modified Gastrointestinal Symptom Rating Scale (mGSRS) and QoL questionnaire distributed via post or email. Participants assessed their QoL on a self-reported Likert-scale (0-10) for their own subjective QoL perception. SPSS statistical software was employed to explore correlations between post-surgery malabsorption and QoL outcomes within this patient cohort. Results Post-surgery, 44.3% of patients encountered weight management challenges, notably within the first year. Malabsorption was prevalent in 69.9% of patients, with common symptoms such as flatulence and reduced appetite. Steatorrhoea, experienced by 47.3% of patients, also commonly caused flatulence and urgent bowel movements. NIS prevalence varied among surgical procedures, with 64.1% post-oesophagectomy and 78% post-gastrectomy, particularly after total gastrectomy. Pancreatic enzyme replacement therapy remained underused at 9.4%. Malabsorption strongly correlated with reduced QoL scores (r=-0.583, p<0.001), regardless of the time elapsed since surgery. Patients with steatorrhoea reported significantly lower QoL scores compared to those without (MD:-1.874, 95% CI, p<0.001). Conclusion The study highlights a significant prevalence of malabsorption and impaired QoL among patients following oesophago-gastric surgery, particularly notable in those experiencing steatorrhoea. Despite medical advancements, these issues often go unrecognized. The multifaceted nature of NIS and their impact on QoL necessitate a multidisciplinary approach involving gastroenterologists, dietitians, and other healthcare professionals. This collaborative effort aims to identify underlying factors contributing to malabsorption, provide consistent dietetics support, and manage symptoms effectively throughout the patient's recovery. Standardised guidelines are essential for ensuring comprehensive care and addressing both physical and psychosocial aspects, thereby enhancing overall postoperative QoL and long-term health outcomes.
