Patients' preferences for low rectal cancer surgery

AimTo elicit surgery preferences of patients who have experience with either low anterior resection (LAR) or abdominoperineal resection (APR) and its outcomes, to support decision-making in future patients with resectable rectal cancer.MethodsOne hundred and twenty-two patients were interviewed. Surgery preference was assessed in two ways. In the treatment trade-off method, the certainty of a stoma was hypothetically weighed against the risk of incontinence. In the time trade-off method, remaining life expectancy was traded off to avoid a permanent stoma or faecal incontinence.ResultsTo avoid APR, LAR patients accepted a much higher risk of incontinence than APR patients. In fact, 71% of the LAR patients chose LAR if they would certainly suffer monthly incontinence, and still 32% if they would certainly suffer daily incontinence. Nevertheless, APR patients would give up less remaining life years to be without a permanent stoma than LAR patients to be without monthly incontinence.ConclusionsMost patients preferred LAR above APR, even if LAR involved a risk of faecal incontinence. This seems to justify that LAR, if surgically possible, is performed in the first instance. However, since APR patients could live well with a permanent stoma, we recommend clearly informing patients before surgery about the surgical options and their potential outcomes.
