Our aim was to evaluate the prevalence and bother of major LARS after one and two years, identify possible risk factors and relate the bowel function to a reference population. METHOD The QoLiRECT (Quality of Life in RECTal cancer) study is a Scandinavian prospective multicentre study including 1248 patients with rectal cancer of whom 552 had an anterior resection. Patient questionnaires were distributed at diagnosis and after one, two and five years. Data from the baseline, and at one and two years follow-up were included in this study. RESULTS LARS score was calculated for 309 patients at one year and 334 patients at two years. Prevalence was assessed by a generalised linear mixed effect model. Major LARS was 63% at one year and 56% at two years. Bother was 55% at one year and decreased to 46% at two years. Major LARS was most common among younger women (69%). Among younger patients, only marginal improvement was seen over time (63-59%), for older patients there was more improvement (62-52%). In the reference population, the highest prevalence of major LARS-like symptoms was noted in older women (12%). Preoperative radiotherapy, defunctioning stoma and tumour height were found to be associated with major LARS. CONCLUSION Major LARS is common and possibly persistent over time. Younger patients, especially women, are more affected and perhaps these patients should be prioritised for early stoma closure to improve the chance of a more normal bowel function.
