Nutrition Impact Symptoms Are Prognostic of Quality of Life and Mortality after Surgery for Oesophageal Cancer.

We aimed to clarify the influence of nutritional problems after surgery for oesophageal cancer on functional health related quality of life (HRQOL) and survival. A prospective nationwide cohort of oesophageal cancer patients operated 2001-2005 in Sweden with 6 months postoperative follow up was used. Nutritional problems were categorized as low/moderate/severe/very severe based on weight loss and nutrition impact symptoms. An ANCOVA model calculated mean score differences (MD) with 95% confidence intervals (CI) of global quality of life (QOL), social and physical function scores, stratified by preoperative body mass index (BMI) <25 and >= 25. A Cox proportional hazards model produced hazard ratios (HR) with 95% CI for overall 5-year survival. Of 358 patients, 196 (55%) had preoperative BMI >= 25. Very severe and severe nutritional problems were associated with worse HRQOL in both BMI groups. E.g. MD's for global QOL among 'very severe' group was -29 (95% CI -39 - -19) and -20 (95% CI -29 - -11) for <25 and >= 25 BMI, respectively, compared to the 'low' group. Overall 5-year survival among 'very severe' and BMI >= 25 was worse; HR 4.6 (95% CI 1.4-15.6). Intense nutritional problems negatively impact postoperative HRQOL and combined with preoperative BMI >= 25 are associated with poorer 5-year overall survival representing a group needing greater clinical attention.
